INTRODUCTION
This document describes, in conceptual terms, the fire protection features of the Four
Seasons Hotel project in Vail, Colorado.
This package intends to describe, in performance-based language, the overall approach
to active and passive fire protection features in the facility, whether required by Code,
the Authority Having Jurisdictions, or as a result of an Owner request. It also describes
the interaction of these systems in providing an overall coordinated fire protection
package.
FACILITY DESCRIPTION
The Four Seasons Hotel project includes a residential hotel and condominium building
of 10 stories. The building includes hotel guest rooms, fractional ownership residential
units (timeshare), whole ownership residential units (condominiums), employee housing
units, meeting and banquet facilities, a spa, restaurants and associated kitchens, retail,
kids center, and back-of-house support. Two enclosed parking garage levels are also
located at the base of the building.
The building will be situated on a sloping site. The site slopes from the north to the
south, so that portions of Level 2 are exposed to grade on the south side. The main
entrance to the faciliry is on the north side and is accessed from Level 5. Although
Level 2 is at elevation 142', the street on the south side of the property (West Meadow
Drive) is at elevation 152'. The elevation of Level 10 (the highest occupied floor) is
222'. The overall facility is considered a low-rise structure, as the highest occupied floor
(Level 10) is less than 75-feet from the lowest level of Fire Department vehicle access.
The building will be constructed under the provisions of the 2003 editions of the
International Codes. The building will be treated as one overall building and will have
non-separated uses as allowed by code. The building will be constructed of Type 1 B
non-combustible materials. Wood trim and fascia is proposed for placement on the
exterior walls of the building. These elements will not be considered building
construction materials, rather they will be considered exterior wall treatment and
finishes. Where large wood members are used, they will comply with the requirements
for heavy timber.

APPLICABLE CODES
This outline documents general fire protection features based upon the requirements of
the Town of Vail Building and Fire Departments. The applicable codes for this project
include:
1. International Building Code (IBC) - 2003 Edition.
2. International Fire Code (IFC) - 2003 Edition
3. International Mechanical Code (IMC) - 2003 Edition
4. International Plumbing Code (IPC) - 2003 Edition
5. National Electric Code (NEC) - 2002 Edition
6. Town of Vail Local Amendments
This report addresses the key features of these Codes and Guidelines. The primary
intent of this document is to coordinate the fire protection approach between all design
disciplines. Details of compliance are left to the construction documents and the
contractors.
KEYISSUES
The building will be constructed of non-combustible materials as required by Section
602 for Type 1 B construction. Wood may be used as part of decorative trim and other
elements within and on the building as allowed by Section 603 of the code. Wood may
be used on the exterior walls of the building as outlined in Section 1405.4. Where wood
is placed more than 3 stories above grade, the wood will be fire retardant treated.
Wood materials may also be used on the exterior walls to form balconies and eaves.
These materials will not be part of the structural elements of the balconies or roof and
will comply with the requirements for heavy timber materials.

The toilet exhaust shafts for the residential units will be provided with 22-inch sub-ducts and will have the exhaust fans continuously operating. While the code specifically
allows the fire damper to be eliminated with the sub-duct, the code does not specifically
address the elimination of the smoke damper for this occupancy. The code does allow
the smoke damper to be eliminated in other occupancies (Group B) when the fan is
continuously operating. This report requests elimination of the smoke damper on the
toilet exhaust shafts for the residential units as an alternate approach to meeting the
intent of code. Protection of the shaft is provided by means of constant airflow from the
exhaust fan, which will be protected using the requirements for smoke control fans as
outlined in Section 909 of the Code. Refer to Appendix C for a copy of this Request.
FIRE PROTECTION OUTLINE
This outline presents conceptual information regarding the proposed fire protection
systems and their performance. This report is intended to be coordinated with the permit
drawings for the facility. Where there are conflicts, this report will take precedence.

TOILET EXHAUST FIRE AND SMOKE DAMPER ELIMINATION
Introduction: Shaft enclosures for the purpose of air transfer create a
passage for the accumulation and spread of hot smoke and
gases from a fire to upper stories of a building (chimney
effect). As such, the 2003 International Building Code (IBC)
recognizes this and is very cautious in protecting
penetrations of such shaft enclosures by requiring fire
dampers and smoke dampers in locations where these
products of fire can escape the shaft and travel into the
building at other floor levels. The majority of deaths in fires
are a result of smoke and proper design and construction
can help minimize the travel of smoke into occupied fiioor
areas.
Code Section: Section 716.5.3.1 of the 2003 IBC, establishes the
requirements for penetration of shaft enclosures by ducts
and air transfer openings, when the shaft enclosure is
permitted to be penetrated. '
Code Requirement: Section 716.5.3.1 of the 2003 IBC requires penetrations of
shaft enclosures by ducts and air transfer openings to be
protected with approved fire dampers and smoke dampers
installed in accordance to their listing.

Exception 1.1 of this section allows the elimination of fire
dampers at penetration of shaft enclosures by steel exhaust
sub-ducts that extend at least 22 inches vertically in exhaust
shafts provided there is a continuous airflow upward to the
outside.
Exception 2.1 of this section also allows the elimination of
smoke dampers on shafts serving bathroom and toilet
exhaust openings in Group B occupancies; provided the
building is equipped throughout by an automatic sprinkler
systern, the shaft is equipped with steel exhaust sub-ducts ,
extending at least 22-inches vertically, the exhaust fan is at
the upper terminus, the fan is powered continuously with the
provisions of Section 909.11, and maintains airtlow upward
to the outside.
Code Intent: Section 716.5.3.1 requires both fire and smoke dampers at
duct and air transfer openings in the shaft wall. The fire
damper is required due to the penetration of a fire-resistance
rated shaft, and to limit the migration of smoke to other parts
of the building via the shaft and the chimney effect.
The code recognizes that a continuous airflow upward will
create a negative pressure in the shaft as compared to
adjacent spaces, thereby minimizing the spread of hot gases
and smoke from the shaft.
The code also recognizes that the likelihood of smoke being
capable of spreading to spaces adjacent to the shaft is
increased if the steel exhaust duct is not in a building
equipped throughout with automatic sprinkler protection, the
exhaust is something greater than that expected of a
bathroom and toilet room exhaust, the exhaust duct wall
thickness is less than 0.019 inches, and the exhaust fan is
not treated as a life safety component by powering the
exhaust fan continuously just like the power for smoke
control systems in Section 909.11, 2003 IBC.

Request: To allow the elimination of smoke dampers for toilet exhaust
shafts for the Four Seasons Hotel as allowed for Group B
building occupancies by Section 716.5.3.1, Exception 2.1,
2003 I BC. Justification: Regardless of the building occupancy classification, the
physics of establishing a continuous exhaust in a shaft to
create a negative pressure relative to adjacent spaces to the
shaft will still exist. The only difference in a Group B versus a
Group R occupancy is the potential for familiarity with the
surroundings in an office environment as opposed to a hotel.
However, the intent of the code for protection of the shaft is
still maintained using the provisions of this exception.
The negative pressure created within the shaft by the
continuously operating fan provides for protection of the
shaft from smoke as it is unlikely that smoke will spread to
other floors once it enters the shaft. The upward flow of air
will create a condition that effectively provides the same
level of protection as the installation of a smoke damper.
The continuously operating fan in accordance with Section
909.11 will provide for reliability of the fan as would be
required for smoke control systems. This provides a level of
, protection consistent with the code for protection of the shaft.
Summary: This request provides a level of protection and life safety that
meets the intent required by Code. Regardless of the
building occupancy classification, when built in accordance
with code exception requirements, the elimination of the
smoke damper at the penetration of the exhaust shaft
enclosure by a bathroom or toilet exhaust sub-duct that
extends at least 22 inches vertically and has a minimum wall
thickness of 0.019 inches in an exhaust shaft with
continuously powered fans equivalent to continuous power
for smoke control exhaust fans; the level of protection for life
safety afforded by the code is met.

Exterior Combustible Siding & Materials
Introduction: The Four Seasons Resort in Vail, Colorado will be `constructed as a Type IB building. As such, the International
Building Code (16C) 2003 edition defines this building as
non-combustible. This requires the building to be ~
constructed of materials that are non-combustible and the .f
use of combustible materials in finish and exterior
applications is restricted. This is to reduce the potential for ~
fires to spread in non-combustible construction. The Four
Seasons Resort proposes to use wood trim on the exterior
walls as part of the decorative materials.
Code Section: Section 603 of the 2003 IBC, establishes the requirements
for use of combustible material in Type I and 11 construction.
~Chapter 14 also regulates the use of combustible materials
on exterior walls.
Code Requirement: Section 603 of the 2003 IBC allows the use of combustible
materials within and on the exterior of the building in certain
conditions. Where not installed over 15 feet from grade, the
use of wood products of any dimension may be used as trim
and similar applications. Section 1405.4 also allows the use
of wood veneers on exterior walls when not less than 1-inch
for hardwood and 3/8-inch for structural panels or
particleboard. These veneers can be used on the exterior
walls up to three stories from grade and up to four stories
when fire retardant treated. The Code also allows the use of
heavy timber for combustible projections regardless of height
above grade.

EXTERIOR COMBUSTIBLE MATERIALS - DRAFT-
Code Intent: The intent of the Code to limit combustible materials within
and on non-cambustible buildings is to reduce the fuel loads
associated with these combustible materials. The Code
allows non-combustible buildings to be af larger size and
greater area than combustible type construction. This is due
to the inherent benefit of non-combustible construction in
reducing the potential for fires and to also control the spread
of fires. Therefore, the use of combustible materials as
finish and siding is regulated for these types of buildings.
Request: To allow the use of wood trim and decorative elements on
the exterior of the building including those areas that will
exceed three stories above grade. ~
i'
Justification: The Code recognizes that the use of wood veneers and
siding is acceptable for non-combustible construction as long
as the height above grade is limited. This restriction is
intended to reduce the potential for fire spread on the
exterior of the building to areas above effective hose
streams from responding personnel and to limit the spread of
fire to the upper floors of a building. The Code allows
materials to be provided that are of minimal size or thickness
in these applicatians.
The proposed use of wood trim for the Four Seasons Resorf
does not reduce the level of protection regulated by these
sections, as the potential for fire spread is minimized due to
the size, location, and application of the wood elements.
It is proposed to provide wood as decorative elements only
and it will not be part of the structural elements of the
building. This will include door and window trim (2-inch
nominal thickness), fascia boards, balcony posts, brackets,
and "trusses". All of these elements, with the exception of
the two inch door and window trim, wiN have a minimum
nominal dimension of no less than 3-inches, so as to
conform to heavy timber material classifications.
The use of wood on the exterior walls is limited for this
project. The primary exterior materials are all non-
combustible stone, plaster and fiber-cement siding. The use
of wood is limited, including the areas of the building that
exceed three stories. The potential for fire spread in the
wood elements is limited, since they are mostly heavy
timber. This is also recognized by the IBC in Section 704.2

that allows balconies or similar projections to be of heavy
timber construction when installed on buildings of Type I or II
construction, without limitation to the height above grade.
The use of heavy timber products in the proposed
application for this project meets the intent of these sections.
Summary: This request provides a level of protection and life safety that
meets the intent required by Code. Although the use of
combustible materials on the exterior walls for this project
exceed the height allowed by Code, the type and application
of the wood material reduces the impact for fire spread. The
majority of the exterior materials are fully non-combustible.
It is either cement board or stone products. The combustible
materials are used for trim and decorative framing. The
decorative framing members are of substantial thickness
meeting heavy timber criteria. The potential for fire spread in
these elements is minimal. It is unlikely that fire will spread
up the exterior wall through the heavy timber materials. In
addition, the amount of combustible materials used
throughout the entire exterior wall under the proposed
application is less than would be allowed if used throughout
the three stories allowed by Code.

Toilet Exhaust Fire and Smoke Damper Elimination
{ntroduction: Shafts within a building provide a means for vertical transfer
of fire and products of combustion if not properly protected.
The International Building Code (IBC) 2003 edition requires
protection of shafts with fire-resistive construction based on
the building construction type and the amount of floors being
served. For this project, 2-hour fire-resistive construction of
vertical shafts is required. Openings in shafts are also
required to be protected to prevent migration of smoke and
products of combustion from transferring to upper floors:
Where ductwork penetrate shafts, fire and smoke dampers
are typically required. However, the IBC recognizes
alternative means to protect these penetrations. These
include metal sub-ducts and continuously operating exhaust
fans.
Code Section: Section 716.5.3.1 of the 2003 IBC, establishes the
requirements for penetration of shaft enclosures by ducts
and air transfer openings, when the shaft enclosure is
permitted to be penetrated.
Code Requirement: Section 716.5.3.1 of the 2003 IBC requires penetrations of
shaft enclosures by ducts and air transfer openings to be

Exception 1.1 of this section allows the elimination of fire
dampers at penetration of shaft enclosures by steei exhaust

building is equipped throughout by an automatic sprinkler
system, the shaft is equipped with steel exhaust sub-ducts
extending at least 22-inches vertically, the exhaust fan is at
the upper terminus, the fan is powered continuously with the
provisions of Section 909.11, and maintains airflow upward

Code Intent: Section 716.5.3.1 requires both fire and smoke dampers at
duct and air transfer openings in the shaft wall. The fire
damper is required due to the penetration of a fire-resistance

shafts serving hotel guest rooms and residential units for the
Four Seasons Hotel as allowed for Group B building
occupancies by Section 716.5.3.1, Exception 2.1, 2003 IBC.
Justification: The Code recognizes the elimination of smoke dampers in
continuously operating exhaust shafts for Group B
occupancies. This is due to the ability of the continuous
exhaust system to create a negative pressure within the duct
which will limit the migration of smoke outside the shaft on
upper floors. It also recognizes that Group B occupancies
do not contain s{eeping areas where people are not able to
immediately detect a fire, should they be asleep.

TOILET EXHAUST FIRE AND SMOKE DAMPER ELIMINATION - DRAFT-
Regardless of the building occupancy classification,
establishing a continuous exhaust in a shaft to create a
negative pressure relative to adjacent spaces to the shaft will
still limit the migration of smoke outside the shaft on upper
floors. The intent of the code for protection of the shaft is
still maintained using the provisions of this exception for
Group R occupancies.
The negative pressure created within the shaft by the continuously operating fan provides for protection of the
shaft from smoke as it is unlikely that smoke will spread to
other floors once it enters the shaft. The upward flow of air
will create a condition that effectively provides the same
level of protection as the installation of a smoke damper.
The sub-duct provided to eliminate the fire damper also
provides additional protection for smoke migration from the
shaft to the room, as smoke would need to travel out of the
negatively pressurized shaft down through the sub-duct to
enter the room.
The continuously operating fan in accordance with Section
909.11 will provide for reliability of the fan as would be
required for smoke control systems. This provides a fevel of
protection consistent with the code for protection of the shaft.
The use of this exception on the residential unit toilet
exhaust systems does not reduce the level of protection to
the building occupants, even though they may not be readily
able to detect a fire condition. Each residential unit will be
equipped with monitored smoke detectors so that a fire
within a guest room or residential unit will report on the fire
alarm system. This will allow in-house personnel to
investigate the situation should the fire not be of sufficient
size to activate the automatic sprinkler system within the
room. Monitored detection within each room provides early
warning not only to the occupants of the room, but also to in-
house staff who can investigate the cause of the alarm.
The residential areas of the hotel are also provided with
automatic sprinkler protection throughout as required by
Code. Quick response sprinklers are required within each
residential unit, including the condominiums, timeshares,
employee housing and hotel guest rooms and suites. The
quick response sprinklers will also provide ear{y detection
ADMINISTRATIVE MODIFICATION REQUEST V31063 - Page 4
FOUR SEASONS HOTEL March 17, 2006
TOILET EXHAUST FIRE AND SMOKE DAMPER ELIMINATION - DRAFT-
and suppression of a fire that may occur within a residential
unit. This will assist in evacuation of floors that may be
affected by a fire within a residential unit, whether it is not
occupied or if the occupants are asleep.
In addition to the monitored residential unit detectors, some
of the stairs that serve the residential and hotel guest room
wings will be pressurized. These include stairs A, B and C.
These stairs will assist in evacuation of the building under
fire alarm conditions within the building. They will also allow
for fire department responding personnel to assist in the
evacuation of the building, since they will provide access to
all levels of the residential unit floors.
The configuration of the building also allows for two sets of
elevators to serve each of the residential floors. These
elevators essentially serve each of the two wings where
residential units (condominium units, timeshares and
employee housing) and hotel guest rooms and suites occur.
The elevators are of sufficient size to allow for fire
department staging and will assist in emergency operations.
These elevators will have pressurized hoistways to reduce
the impact of smoke that may migrate into the shaft and
transfer to other floors.
Summary: This request provides a level of protection and life safety that
meets the intent required by Code. Regardless of the
building occupancy classification, when built in accordance
with code exception requirements, the elimination of the
smoke damper at the penetration of the exhaust shaft
enclosure the level of protection for life safety afforded by
the code is met. Since the toilet exhaust shafts will serve
residential unit floors, upgraded protection of the stairs and
elevators will allow for safe evacuation and emergency
staging operations. Monitored detection within each room
also provides for early warning in the event a fire occurs
within a residential unit or hotel guest room when it is not
occupied or the occupants are asleep. This early warning
helps mitigate the concerns of the model code in the
elimination of smoke dampers for residential occupancies.

Vail Viltage and LionsHead Viliage Construction Hours
~ Information liandout
~ Problem Statement
~ The Vail Village and LionsHead Village are invaluable assets to the community. Thousands of people come to Vail each year to
sightsee, recreate, shop and to enjoy everything the Vail Valley has to offer. The communlty and merchants rely upon our guests to
~ generate revenue. Our summer/winter guests expect a pleasant experience while in Vail.
~ To insure that a!I of the proposed construction has as little negative impact on the community and on our guest as possible, the Town
of Vail finds it imperative to create and implement the Vail Village and LionsHead Village Construction Hours Handout.
~
It would be irresponsibte for the Town of Vail, the construction contractors and the merchants, to not actively participate to minimize
~ the impact of construction in the Vail and LionsHead Village areas.
¦ The Vail Viliage Streetscape Project wil6 continue through 2006. Improvements scheduied for
~ 2006 wBil be concentrated along Gore Creek Drive west of the Children's Fountain, Gore Creek
Promenade and around the frontage of the Nlill Creek Court Builtiing. Additaonal streetscape
~ improvements are scheduled to begin along East Meadow Drive.
AlA construction projects and/or remodels anrithin the Vail Village Core Area should contact
¦ Scott Bluhon, Town of Vail Streetscape Coordinator, at 970-477-3418 for further information.
¦ Givens
~ The foilowing givens are intended to provide the basic foundation by which construction will be completed in
~ the villages:
~ The public's health, safety and welfare shall be honored at all times.
~ Adequate pedestrian, load i ng/del ivery, vehicle, and emergency vehicle access and circulation shall be
~ maintained.
~ Roadways and pedestrian walkways shall be kept clean and free of dirt and debris.
¦ All construction deliveries, equipment, tools and materials entering the Vail Village and pedestrian areas
~ must go through CheckPoint Charlie. All LionsHead construction activity must go to the Vail Police
Department for a parking permit. Do not use delivery zones for construction parking; refer to approved
~ staging plan or make other arrangements for parking.
¦ The hours of outside construction activity shall be as follows:
~ - April 15 - June 23 & September 5- November 17, 7:00 a.m. until 7:00 p.m., seven days a week.

INTRODUCTION
This Memorandum of Understanding (MOU) request is the documentation of several
meetings and discussions with the Town of Vail Building and Fire Department. The
intent of this correspondence is to "document" how the design team will comply with the
requirements of the adopted building and fire codes as adopted by the Town of Vail.
This document differs from the Request for Administrative Modification in that we are
not requesting any variance from the adopted building and fire codes. This document
should be a,reference to and complement the Life Safety Report and Construction
Documents prepared by the design team. Once siqned bv all parties (signature page),
the described qortions of the Fire Protection and Life Safetv code repuirement are
considered to be clarification of the buildinq or fire code for the desi4n and construction
of The Four Seasons Hotel in Vail.
1. SMOKE MANAGEMENT SYSTEM (STAIRS AND ELEVATOR HOISTWAYS)
The building is not considered a high-rise structure, however, at the August 24,
2005 meeting with the TOV Fire Department; RJA presented the fire department
~ access and the location of the fire command center. The TOV fire department
agreed the building was not a high-rise but requested that a"performance
approach" be taken for the building and that the design team provide a smoke
management system in designated stair enclosures and elevator hoist-ways. It
was determined that the designated stairs and elevator hoist-ways would serve
all levels of the building and be accessible from the main entrance near the fire
command center. The following stair enclosures and elevator hoist-ways will be

provided with a smoke management system via smoke pressurization:
• Stair Enclosure A
• Elevator Hoist-way directly south of Stair Enclosure A(Elevators RS1 and
RS2)
0 Stair Enclosures B and C
• Elevator Hoist-way south of Stair Enclosure C, east of Stair Enclosure B
(Elevators HS1 and HS2)
The stair and hoist-way enclosures will be provided with a smoke management
or pressurization system designed to meet the following criteria:
• Stairwell Enclosures - The smoke management system for the
designated stairwell enclosures will consist of a pressurization fan for the
designated stairnrell activated automatically upon fire alarm activation
(water-flow or detection). The system will be designed such that during ~
operation the doors into the stairwell will not require more than 30-pounds ~
of force to open, regardless of the barometric pressures of the
~ environment. We discussed that the system will r`~t need to be designed
to any minimum pressure differential such as 0.05 inches of water column
but it would be enough to keep the stairwell positive in relation to adjacent
spaces. A smoke management system will to be designed by a fire
protection engineer and submitted to the fire department for their review
and approval.
• Elevator Hoist-way - The smoke management system for the designated
elevator hoist-ways will consist of a pressurization fan for the elevator
shafts activated upon fire alarm activation (water-flow or detection). The
smoke management system will not need to be designed to any minimum
pressure differential. However, the system will be designed to keep the
% elevator positive in relation to the adjacent spaces or elevator lobbies.
' The positive pressure will extend beyond the hoist-way into the elevator
lobbies or adjacent corridors. It is intended that the smoke management
system will prevent smoke from migrating from floor to floor via the
/ identified elevator hoist-way or stair enclosure.
~ Emergency Power and Control - The smoke management system will be
connected to the building emergency power system since this is a life
safety system. The smoke management system will also be manually
controlled from the fire command center utilizing an approved smoke
control panel.

2. FIRE COMMAND ROOM
At numerous meetings with the TOV fire department, RJA and the design team
presented the fire department access and the location of the fire command room.
The TOV fire department agreed the building was not a high-rise but requested
that a fire command be provided. It was agreed to by the team that the fire
command center would be located near the entrance of the building near the
"valet office". Further clarification from the fire department also required that the
fire command room would not be shared with any other hotel function and would
require direct access to the exterior. The currently approved location provides a
central response point for the fire department with access to stairs serving the
building and an elevator serving all levels of the building. The fire command room
location has been approved under separate signature by the fire department '
(attached). Listed below are the components that will be included in the fire
command room:
• Annunciators for the fire alarm system.
• Standby and emergency power status.
• Public address, voice communication system status and controls.
• A direct dial telephone.
• A table for reviewing building plans and schematic diagrams.
• Schematic building plans, including typical floor plans, egress drawings,
fire protection systems, smoke control diagrams, fire-fighting equipment
and fire department access.
• Keys to access all portions of the building.
3. EXTERIOR COMBUSTIBLE SIDING AND MATERIALS
The building will be constructed of non-combustible materials as required by
Section 602 for Type 1 B construction. As described in the Life Safety Report
wood or combustible material will be used as part of decorative trim and other
elements within and on the building as allowed by Section 603 of the code.
Wood will be used on the exterior walls of the building as outlined in Section
ROLF JENSEN 8 ASSOCIATES, INC
THE FOUR SEASONS HOTEL PAGE 4
MEMORANDUM OF UNDERSTANDING January 17, 2006
VAIL, COLORADO
1405.4. Exterior wood elements will be located so as to avoid vertical fuel chains
on the building. This will limit the ability of a fire to spread through these areas.
On October 27, 2005 Mike McGee, Fire Marshal with TOVFD met with members
of the design team and provided guidance for the use of combustible material on
the exterior of the building. This MOU documents those permitted combustible
materials on the exterior of the building will be permitted if they meet the
following:
• Wood materials used on the exterior walls to form balconies and eaves
will not be part of the structural elements supporting the balconies or roof.
If such and will comply with the requirements for heavy timber materials,
as outlined in Section 602.4 of the Code.
• Fascia boards and "belly bands" will be made of 3x timber material.
~ • Wood trim around doors and windows would be Permitted. (2x timber
~
material)
~ Currently the design team is proceeding utilizing these assumptions and will
comply with the provisions identified above.
4. GRAND STAIR in COMMUNICATING SPACE at HOTEL LOBBY
C
The Hotel Lobby by definition is considered to be an atrium. The grand stair
connects levels 3 and 5. It is the intent of this design to communicate through
only 2 floors. As we've discussed in previous meetings it is our interpretatfon and
intent that a smoke control system would not be required as guided by the
exceptions in the building code. Adjacent to the communicating space is a
mechanical mezzanine on Level 04 that will be separated by a 2 hour fire barrier.
At a meeting with the TOV building and fire department on August 24, 2005 it
was concurred by those in attendance that the atrium does not communicate
through more than 2 floors by its adjacency to the mechanical mezzanine space.
This interpretation was supported by TOV building and fire department and
Colorado Inspection Agency (TOV Plan Review Consultant). The current Life
Safety Report and Life Safery Drawings indicate a 2 hour fire barrier separating
the mechanical mezzanine from the adjoining spaces. Based on this MOU the
design team is not intending to provide a smoke control system in this grand stair
location. The TOV Fire Department also requested that sprinkler protection be
provided under the slope of the grand stair and that a draft stop or partial barrier
be provided to help prevent smoke from migrating up the grand stair to the
communicating floor above the lobby. This draft stop will consist of a ceiling soffit

VAIL, COLORADO
that is 12 inches deep,
5. TOILET EXHAUST and FIRE DAMPER REQUIREMENT
The design team has had discussions related to the providing fire dampers in the
residential unit toilet exhaust shafts. The toilet exhaust shafts for the residential
units will be provided with 22-inch sub-ducts and will have the exhaust fans
continuously operating. While the code allows the fire damper to be eliminated,
the code does not address the elimination of the smoke damper in a residential
occupancy. The code does allow the smoke damper to be eliminated in Group B
occupancies when the fan is continuously operating. This MOU requests
elimination of the smoke damper on the toilet exhaust shafts for the residential
units as an alternate approach.
~ ~
6. EMERGENCY GENERATOR - NAAS~ Vd~'
There has been discussion with the fire department regarding the use of natural
gas in lieu of diesel fuel as the fuel source for the emergency generator. The
design team has decided to proceed with the design and installation of an
emergency generator powered by natural gas. The electrical engineer (RYBKA)
has indicated that the National Electrical Code has a provision (attached) that
would require that an alternate fuel source would be required if natural gas is
utilized for powering the emergency generator. There is an exception to this
requirement that allows the use of natural gas only if approved by the authority
having jurisdiction (TOV Fire Department). Based on the numerous discussions
we've had with the fire marshal and his support for the use of natural gas and
understanding that natural gas is a very reliable fuel source for emergency
generators, this MOU would document that a dual fuel source would not be
required for this emergency generator. The design team is proceeding with the
design and installation of the emergency generator utilizing a primary fuel source
of natural gas only.
RECOMMENDATION
This MOU in conjunction with the current design documents provides a level of
protection and life safety that meets the intent and spirit of the Code and therefore does
not create a hazardous condition to the occupants of the building.

FIRE & LIFE SAFETY REPORT V31063 - Page 1
FOUR SEASONS HOTEL April 28, 2006
VAIL, COLORADO
INTRODUCTION
~ This document describes, in conceptual terms, the fire protection features of the Four
Seasons Hotel project in Vail, Colorado.
This package intends to describe, in performance-based language, the overall approach
to active. and passive _fire pcotection featuces. in. the facility.,_ whether required by Code, .
the Authority Having Jurisdictions, or as a result of an Owner request. It also describes
~ the interaction of these systems in providing an overall coordinated fire protection
package, This Life Safety Report has been modified based on additional meetings with
the Town of Vail (TOV) Building and Fire Departments and the TOV plan review and
inspection contractor, Colorado Inspection Agency.
FACILITY DESCRIPTION
~
The Four Seasons Hotel project includes a residential hotel and condominium building
of 10 stories. The building includes hotel guest rooms, fractional ownership residential
units (timeshare), whole ownership residential units (condominiums), employee housing
units, meeting and banquet facilities, a spa, restaurants and associated kitchens, retail,
kids center, and back-of-house support. Two enclosed parking garage levels are also
~r located at the base of the building.
~ The building will be situated on a sloping site. The site slopes from the north to the `
south, so that portions of Level 2 are exposed to grade on the south side. The main
entrance to the facility is on the north side and is accessed from Level 5. Although
~ Level 2 is at elevation 142', the street on the south side of the property (West Meadow
Drive) is at elevation 152'. The elevation of Level 10 (the highest occupied floor) is
222'. The overall facility is considered a low-rise structure, as the highest occupied floor
(Level 10) is less than 75-feet from the lowest level of Fire Department vehicle access.
The building will be constructed under the provisions of the 2003 editions of the
~ International Codes. The building will be treated as one overall building and will have
, non-separated uses as allowed by code. The building will be constructed of Type 1 B
non-combustible materials. Wood trim and fascia is proposed for placement on the
exterior walls of the building. Please refer to the Administrative Modification Request
No. 2 in the Appendix of this report.

Except for.the parking garage and storage_ areas, which will be_.
separated from the remainder of the building as required for
~ incidental use, all other uses have unlimited area requirements
, based on Table 503. With the overall area of the garage and
storage uses being within the allowable area requirements, the
building will be treated as a non-separated mixed use occupancy as
outlined in IBC Section 302.3. Therefore, fire-separation
assemblies will not be provided between use groups. Fire rated
~ assemblies will be provided for incidental use areas as noted
below.
~ 2. The lower two floors contain garage and storage occupancies
which have maximum allowable areas per Table 503 of the Code,

and storage uses. The garage represents approximately
~ 52,235 square feet. The remainder of the space includes
mechanical, storage and electrical type rooms, some of
which do not have maximum allowable areas per Table 503.
~ However, even with these uses included in the area
calculations for S-1 occupancies, the ratio of actual use to
allowable use is 0.834. For Level 2, the overall area is
~ 36,500 square feet for the garage and storage areas, with
the garage representing approximately 33,600 square feet.
Based on these areas, the ratio of actual use to allowable
~ use is 0.485.

~ D. Non-simultaneous uses.
~ 1. Public area rest rooms, and the Pre-Function areas within the
Ballroom areas, will be considered non-simultaneously occupied
within the area they serve. These areas will be provided with
sufficient exiting based on the use of the area, however their loads
_ will not be included in_the_overall_loads for the building._ RJA has--
evaluated the egress of the current design with respect to the pre-
~ function area and assembly area being used simultaneously.
Currently there is adequate egress capacity for the Ballroom and
Conference Areas.
~ 2. The exit diagrams submitted for this project will include an analysis
of the expected uses of the Ballroom and Pre-Function spaces. It
~ is anticipated that the Ballroom will be used for concentrated and
non-concentrated uses. When the Ballroom is being used for
concentrated use (occupant load factor of 1 person per 7 square
~ feet), it is expected that the Pre-Function areas will be used as
circulation and that the use will be non-simultaneous. When the
Ballroom is being used for non-concentrated use (1 person per 15
square feet), it is expected that the Pre-Function areas will be
simultaneously occupied at the same use. This allows for exhibit
shows within the Ballroom areas to have setup and booths in the
~ Pre-Function spaces as well. 'Under these two scenarios, the
heaviest occupant load is when the Ballroom has concentrated use.
RJA has evaluated the egress of the current design with respect to
~ the pre-function area and assembly area being used
simultaneously. Currently there is adequate egress capacity for the
Ballroom and Conference Areas.
~ E. Exit routes from building.
I 1. Above-grade levels.
a. Exits will be into enclosed stairwells.
~ b. Stairwefls will discharge directly to the exterior at grade
levels.

' INTRODUCTION
This Memorandum of Understanding (MOU) request is the documentation of several
' meetings and discussions with the Town of Vail Building and Fire Department. The
intent of this correspondence is to "document" how the design team will comply with the
requirements of the Building and Fire Codes as adopted by the Town of Vail. This
' document differs from the Request for Administrative Modification in that we are not
requesting any variance from the adopted Building and Fire Codes. This document
should be a reference to and complement the Life Safety Report and Construction
' Documents prepared by the design team. Once signed by all parties (signature page),
the described portions of the Fire Protection and Life Safety code requirement are
considered to be clarification of the building or fire code for the design and construction
' of The Four Seasons Hotel in Vail.
, 1. SMOKE MANAGEMENT SYSTEM (STAIRS AND ELEVATOR HOISTWAYS)
The building is not considered a high-rise structure, however, at the August 24,
, 2005 meeting with the TOV Fire Department; RJA presented the Fire Department
access and the location of the fire command center. The TOV fire department
agreed the building was not a high-rise but requested that a"performance
, approach" be taken for the building and that the design team provide a smoke
management system in designated stair enclosures and elevator hoist-ways. It

' was determined that the designated stairs and elevator hoist-ways would serve
all levels of the building and be accessibte from the main entrance near the fire
, command center. The foflowing stair enclosures and elevator hoist-ways will be
provided with a smoke management system via smoke pressurization:
~ .
• Stair Enclosure A
• Elevator Hoist-way directly south of Stair Enclosure A(Elevators RS1 and
~ RS2)
• Stair Enclosures B and C
• Elevator Hoist-way south of Stair Enclosure C, east of Stair Enclosure B
' (Elevators HS1 and HS2)
The stair and hoist-way enclosures will be provided with a smoke management
, or pressurization system designed to meet the following criteria:
• Stairwell Enclosures - The smoke management system for the designated
, stairwell enclosures will consist of a pressurization fan for the designated
stairwell activated automatically upon fire alarm activation (water-flow or
detection). The system will be designed such that during operation the
, doors into the stairwell will not require more than 30-pounds of force to
open, regardless of the barometric pressures of the environment. We
discussed that the system will not need to be designed to any minimum
' pressure differential such as 0.05 inches of water column but it would be .
enough to keep the stairwell positive in relation to adjacent spaces. A
smoke management system will to be designed and submitted to the fire
' department for their review and approval.
• Elevator Hoist-way - The smoke management system for the designated
, elevator hoist-ways will consist of a pressurization fan for the elevator
shafts activated upon fire alarm activation (water-flow or detection). The
smoke management system will not need to be designed to any minimum
' pressure differential. However, the system will be designed to keep the
elevator positive in relation to the adjacent spaces or elevator {obbies. The
positive pressure will extend beyond the hoist-way into the elevator lobbies
, or adjacent corridors. It is intended that the smoke management system
will prevent smoke from migrating from floor to floor via the identified
elevator hoist-way or stair enclosure.

• Emergency Power and Control - The smoke management system will be
, connected to the building emergency power system since this is a life
safety system. The smoke management system will also be manually
controlled form the fire command center utilizing an approved smoke
' control panel.
' 2. FIRE COMMAND ROOM
At numerous meeting with the TOV Fire Department, RJA and the design team
~ presented the Fire Department access and the location of the fire command
room. The TOV Fire Department agreed the building was not a high-rise but
requested that a fire command room be provided. It was agreed to by the team
that the fire command center would be located near the entrance of the building
~ near the "valet office". Further clarification from the Fire Department also required
that the fire command room would not be shared with any other hotel function and
would require direct access to the exterior. The currently approved location
' provides a central response point for the Fire Department with access to stairs
serving the building and an elevator serving all levels of the building. The fire
command room location has been approved under separate signature by the Fire
, Department. Listed below are the components that will be included in the fire
command room:
' • Annunciators for the fire alarm system.
• Standby and emergency power status.
' • Public address, voice communication s stem status an
y d controls.
, • A direct dial telephone.
• A table for reviewing building plans and schematic diagrams.
~ • Schematic buildin lans includin typi
g p , g cal floor plans, egress drawings,
, fire protection systems, smoke control diagrams, fire-fighting equipment
and fire department access.
• Keys to access all portions of the building.

' 3. GRAND STAIR in COMMUNICATING SPACE at HOTEL LOBBY
t The Hotel Lobby by definition is considered to be an atrium. The grand stair
connects levels 3 and 5. It is the intent of this design to communicate through
only 2 floors. As discussed in previous meetings it is our interpretation and intent
, that a smoke control system would not be required as guided by the exceptions in_ _
the building code. Adjacent to the communicating space is a mechanical
mezzanine on Level 04 that will be separated by a 2 hour fire barrier. At a
, meeting with the TOV Building and Fire Departments on August 24, 2005 it was
concurred by those in attendance that the atrium does not communicate through
more than 2 ftoors by its adjacency to the mechanical mezzanine space. This
' interpretation was supported by TOV Building and Fire Departments and
Cotorado Inspection Agency (TOV Plan Review Consultant). The current Life
Safety Report and Life Safety Drawings indicate a 2 hour fire barrier separating
, the mechanicat mezzanine from the adjoining spaces. Based on this MOU the
design team is not intending to provide a smoke control system in this grand stair
location. The TOV Fire Department afso requested that sprinkler protection be
' provided under the sfope of the grand stair and that a draft stop or partial barrier
be provided to help prevent smoke from migrating up the grand stair to the
communicating floor above the lobby. This draft stop will consist of ceiling soffits
' that are 12 inches deep.
' 4. EMERGENCY GENERATOR - DIESEL POWER
There has been discussion with the Fire Department regarding the use of natural
' gas in lieu of diesef fuel as the fuel source for the emergency generator. The
design team has decided to proceed with the design and installation of an
emergency generator powered by diesel fuel. The electrical engineer (RYBKA)
' has indicated that the National Electrical Code has a provision that would require
that an alternate fuel source would be required if natural gas is utilized for
powering the emergency generator. The design team is proceeding with the
' design and installation of the emergency generator utifizirig a primary fuel source
of diesel fuel. Fuel storage within the generator room will comply with code and
be within exempt amounts as allowed by Chapter 3 of the IBC.
~
RECOMMENDATION
' This MOU in conjunction with the current design documents provides a level of
protection and life safety that meets the intent and spirit of the Code and therefore does
' not create a hazardous condition to the occupants of the building.

' Toilet Exhaust Fire and Smoke Damper Elimination
' Introduction: Shafts within a building provide a means for vertica{ transfer
of fire and products of combustion if not properly protected.
The International Building Code (IBC) 2003 edition requires
, protection of shafts with fire-resistive construction based on
the building construction type and the amount of floors being
served. For this project, 2-hour fire-resistive construction of
1 vertical shafts is required. Openings in shafts are also
required to be protected to prevent migration of smoke and
products of combustion from transferring to upper floors.
, Where ductwork penetrate shafts, fire and smoke dampers
are typically required. However, the fBC recognizes
alternative means to protect these penetrations. These
' include metal sub-ducts and continuously operating exhaust
fans.
' Code Section: Section 716.5.3.1 of the 2003 IBC, establishes the
requirements for penetration of shaft enclosures by ducts
and air transfer openings, when the shaft enclosure is
, permitted to be penetrated.
Code Requirement: Section 716.5.3.1 of the 2003 16C requires penetrations of
shaft enclosures by ducts and air transfer openings to be
~ protected with approved fire dampers and smoke dampers
installed in accordance to their listing.

TOILET EXHAUST FIRE AND SMOKE DAMPER ELIMINATION - DRAFT-.
' Exception 1.1 of this section allows the elimination of fire
dampers at penetration of shaft enclosures by steel exhaust
' sub-ducts that extend at least 22 inches vertically in exhaust
shafts provided there is a continuous airflow upward to the
outside.
Exception 2.1 of this section also allows the elimination of
smoke dampers on shafts serving bathroom and toilet
, exhaust openings in Group B occupancies; provided the
building is equipped throughout by an automatic sprinkler
system, the shaft is equipped with steel exhaust sub-ducts
, extending at least 22-inches vertically, the exhaust fan is at
the upper terminus, the fan is powered continuously with the
provisions of Section 909.11, and maintains airflow upward
~ to the outside.
Code Intent: Section 716.5.3.1 requires both fire and smoke dampers at
1 duct and air transfer openings in the shaft wall. The fire
damper is required due to the penetration of a fire-resistance
rated shaft, and to limit the migration of smoke to other parts
~ of the building via the shaft.
The code recognizes that a continuous airFlow upward will
~ create a negative pressure in the shaft as compared to
adjacent spaces, thereby minimizing the spread of hot gases
and smoke from the shaft.
' Request: To allow the elimination of smoke dampers for toilet exhaust
shafts serving hotei guest rooms and residential units for the
Four Seasons Hotel as allowed for Group B building
' occupancies by Section 716.5.3.1, Exception 2.1, 2003 IBC.
, Justification: The Code recognizes the elimination of smoke dampers in
continuously operating exhaust shafts for Group B
occupancies. This is due to the ability of the continuous
~ exhaust system to create a negative pressure within the duct
which will limit the migration of smoke outside the shaft on
upper floors. It also recognizes that Group B occupancies
' do not contain sleeping areas where people are not able to
immediately detect a fire, should they be asleep.

' Re9ardless of the building occupancy classification,
establishing a continuous exhaust in a shaft to create a
' negative pressure relative to adjacent spaces to the shaft will
still limit the migration of smoke outside the shaft on upper
floors. The intent of the code for protection of the shaft is
~ still maintained using the provisions of this exception for_
- Group R occupancies.
, The negative pressure created within the shaft by the
continuously operating fan provides for protection of the
shaft from smoke as it is unlikely that smoke will spread to
' other floors once it enters the shaft. The upward flow of air
will create a condition that effectively provides the same
_ level of protection as the installation of a smoke damper.
The sub-duct provided to eliminate the fire damper also
provides additional protection for smoke migration from the
shaft to the room, as smoke would need to travel out of the
~ negatively pressurized shaft down through the sub-duct to
enter the room.
' The continuously operating fan in accordance with Section
909.11 will provide for reliability of the fan as would be
required for smoke control systems. These fans will be
~ connected to the buildings emergency generator to provide
the required secondary power supply. This provides a level
of protection consistent with the code for protection of the
~ shaft.
The use of this exception on the residential unit toilet
~ exhaust systems does not reduce the level of protection to
the building occupants, even though they may not be readily
able to detect a fire condition. Each residential unit will be
' equipped with monitored smoke detectors so that a fire
within a guest room or residential unit will report on the fire
alarm system. This will allow in-house personnel to
' investigate the situation should the fire nat be of sufficient
size to activate the automatic sprinkler system within the
room. Monitored detection within each room provides early
~ warning not only to the occupants of the room, but also to in-
house staff who can investigate the cause of the alarm.

' The residential areas of the hotel are also provided with
automatic sprinkler protection throughout as required by
~ Code. Quick response sprinklers are required within each
residential unit, including the condominiums, timeshares,
employee housing and hotel guest rooms and suites. The
~ quick_response sprinklers will also provide early_ detection
- and suppression of a fre that may occur within a residential
unit. This will assist in evacuation of floors that may be
~ affected by a fire within a residential unit, whether it is not
occupied or if the occupants are asleep.
' In addition to the monitored residential unit detectors, some
of the stairs that serve the residential and hotel guest room
wings will be pressurized. These include stairs A, B and C.
~ These stairs will assist in evacuation of the building under
fire alarm conditions within the building. They will also allow
for fire department responding personnel to assist in the
~ evacuation of the building, since they will provide access to
al{ levels of the residential unit floors.
~ The configuration of the building also allows for two sets of
elevators to serve each of the residentiaf floors. These
elevators essentially serve each of the two wings where
' residential units (condominium units, timeshares and
employee housing) and hotel guest rooms and suites occur.
The elevators are of sufficient size to allow for fire
~ department staging and will assist in emergency operations.
These efevators will have pressurized hoistways to reduce
the impact of smoke that may migrate into the shaft and
, transfer to other floors.

building occupancy classification, when built in accordance
with code exception requirements, the elimination of the
smoke damper at the penetration of the exhaust shaft
enclosure the level of protection for.life safety_ afforded by_

staging operations. Monitored detection within each room
~ also provides for early warning in the event a fire occurs
within a residential unit or hotel guest room when it is not
occupied or the occupants are asleep. This early warning
~ helps mitigate the concerns of the model code in the
elimination of smoke dampers for residential occupancies.

' Exterior Combustible Siding & Materials
~ Introduction: The Four Seasons Resort in Vail, Colorado will be
constructed as a Type IB building. As such, the International
Building Code (IBC) 2003 edition defines this buiiding as
' non-combustible. This requires the building to be
constructed of materials that are nan-combustible and the
use of combustible materials in finish and exterior
1 applications is restricted. This is to reduce the potential for
fires to spread in non-combustible construction. The Four
Seasons Resort proposes to use wood trim on the exterior
' walls as part of the decorative materials.
Code Section: Section 603 of the 2003 IBC, establishes the requirements
~ for use of combustible material in Type I and II construction.
Chapter 14 also regulates the use of combustible materials
on exterior walls.
, Code Requirement: Section 603 of the 2003 IBC allows the use of combustible
materials within and on the exterior of the building in certain
~ conditions. Where not installed over 15 feet from grade, the
use of wood products of any dimension may be used as trim
and similar applications. Section 1405.4 also allows the use
' of wood veneers on exterior walls when not less than 1-inch
for hardwood and 3/8-inch for structural panels or
particleboard. These veneers can be used on the exterior
' walls up to three stories from grade and up to four stories
when fire retardant treated. The Code also allows the use of
heavy timber for combustible projections regardless of height
1 above grade.

EXTERIOR COMBUSTIBLE MATERIALS - DRAFT-
~ Code lntent: The intent of the Code to limit combustible materials within
and on non-combustible buildings is to reduce the fuel loads
, associated with these combustible materials. The Code
allows non-combustible buildings to be of larger size and
greater area than combustible type construction. This is due
, to the inherent bene_ft_of non-combustible construction in .
reducing the potential for fires and to also control the spread
of fires. Therefore, the use of combustible materials as
~ finish and siding is regulated for these types of buildings.
Request: To allow the use of wood trim and decorative elements on
~ the exterior of the building including those areas that will
exceed three stories above grade. Please refer to the small-
scale drawings attached to this request.
' Justification: The Code recognizes that the use of wood veneers and
siding is acceptable for non-combustible construction as long
, as the height above grade is limited. This restriction is
intended to reduce the potential for fire spread on the
exterior of the building to areas above effective hose
~ streams from responding personnel and to limit the spread of
fire to the upper floors of a building. The Code allows
materials to be provided that are of minimal size or thickness
' in these applications.
The proposed use of wood trim for the Four Seasons Resort
' does not reduce the level of protection regulated by these
sections, as the potential for fire spread is minimized due to
the size, location, and application of the wood elements.
~ It is proposed to provide wood as decorative elements only
and it will not be part of the structural elements of the
~ building. This will include door and window trim (2-inch
nominal thickness), fascia boards, balcony posts, brackets,
and "trusses". All of these elements, with the exception of
, the two inch door and window trim, will have a minimum
nominal dimension of no less than 3-inches, so as to
conform to heavy timber material classifications.

EXTERIOR COMBUSTIBLE MATERIALS - DRAFT-
'
The use of wood on the exterior walls is limited for this
~ project. The primary exterior materials are all non-
combustible stone, plaster and fiber-cement siding. The use
of wood is limited, including the areas of the building that
exceed three stories. The potential for fire spread in the
wood _elements is limited,. since they are_mostly. heavy_ _
r
timber. This is also recognized by the IBC in Section 704.2
~ that allows balconies or similar projections to be of heavy
timber construction when installed on buildings of Type I or 11
construction, without limitation to the height above grade.
~ The use of heavy timber products in the proposed
application for this project meets the intent of these sections.
~ Summary: This request provides a levet of protection and life safety that
meets the intent required by Code. Although the use of
combustible materials on the exterior walls for this project
, exceed the height allowed by Code, the type and application
of the wood material reduces the impact for fire spread. The
majority of the exterior materials are fully non-combustible.
, It is either cement board or stone products. The combustible
materials are used for trim and decorative framing. The
decorative framing members are of substantial thickness
meeting heavy timber criteria. The potential for fire spread in
~ these elements is minimal. It is unlikely that fire will spread
up the exterior wall through the heavy timber materials. In
addition, the amount of combustible materials used
' throughout the entire exterior wall under the proposed
application is less than would be allowed if used throughout
the three stories allowed by Code.
