MEMORANDUM
To: Mike Ortizllrv Gladstone Vail Recreation District. Stan Zemler Town of Vail
From: Charlie Davis, Chief Building Offrcial
Date: December 12,2003
RX: Oggupant Load Requirements for Dobson Ice Arena
During the 1999 World Alpine Ski Championships, Dobson Ice Arena was evaluated by the Town of Vail's
Building Inspection and Safety Services for use of special events other than an a ice arena. When this
evaluation was completed it was noted that the use ofDobson Ice Arena for special events consistently
exceeded exit capacity for the structure. During the 2001 season the arena was expanded to increase storage
capacity and add additional offrce and bathroom facilities. During that building pennit plan review it was
determined to increase exit widths to allow nore occupants and a performance based approach was
suggested to allow for more occupants to use the arena. While the additional exit width was added, the
smoke-control system required to complete the performaace based approach has yet to be installed.
Because this has not work has not been conpleted, The Town's Building department with agrcement from,
the Town's Fire Department shall require the maximum occupant load for Dobson Ice Arena to be held to a
maximum of 1500 occupants/people. We shall also require that any special event other that ice related
events to be submitted for review and approval, a minimum of l0 business days prior to the event being
held. This is being done to provide a minimum level of safety for occupants attending events at the ice
at€na.
Please make note of the additional attachment recently provided to the Vail Town Council, and the
DepartrDent's position. Please do hesitate to call me if any questions arise

MEMORANDUM
TO: Pam Brandemeyer Interim Town Managerly'ail Town Council
FROM: Charlie Davis Chief Building Official, Michael McGee Fire Marshal/Deputy
Chief
DATE: May 15,2003
SUBJECT: Status of Life Safety lmprovements, John R. Dobson lce Arena
I. DESCRIPTION OF THE REQUEST
This is a synopsis of the status of the life safety improvements to Dobson lce
Arena. The primary purpose of this memo is to pass on information regarding
the project since the status of Dobson lce Arena's occupant load is still in
question.
II. BACKGROUND
We became aware of the nonconforming status of Dobson at the time of the
1999 World Alpine Skiing Championships. lt became apparent that the
maximum permissible occupant load under the 1997 UBC, as adopted by the
Town of Vail, is 1000 persons. The primary reason for the 1,OO0-person cap is
the lack of a fourth (4h) separate exit. There are or were multiple nonconforming
features, including the combustible cedar shake roof, inadequate width of exit
aisles and stairs, lack of a second exit from the refrigeration room, failure to
maintain occupancy separations, questionable operating procedures, etc. The
management for Dobson lce Arena, basically the staff of the Vail Recreation
District (VRD), is regularly booking and holding events, such as rock concerts, in
ihe facility, with 2,500 or more persons in attendance.
The Town Manager directed staff to hire an independent contractor to review
Dobson lce arena for occupancy and apply a performance-based approaches to
resolve building code non-conformities relating to the uses of Dobson lce Arena.
Staff hired ARUP who is considered a leading code consultant in this field in the
counlry.
ARUP's recommendations for life safety improvemenls are contained in their
'Final Report" dated May 2001 (a copy is available if needed). The
recommendations are based, generally, upon the following assumptions:
1) Maximum allowable occupant load, depending upon event scenario, of from
800 to 3,000 persons.
2) A number of set "scenarios" for different types of events, including occupant
loads, layouts of tables, chairs, stages, etc., as applicable to various types of
events that are held in the lacility. The scenarios include hockey games, dinner
dances, open floor concerts, concerts with chairs and the annual ski swap.
1)
3) That the primary goal of the improvements is to safely evacuate occupants
from the building before they are overcome by smoke, heat or other impacts from
a fire in the facility.
4) The knowledge that a fire might partially or completely destroy the building
and might threaten other nearby buildings. The recommended life safety
improvements are not intended to save the slructure, i.e., provide property
protection, or prevent the spread of fire from the structure.
It appears that all of the recommended life safety improvements, wilh the
exception of the recommended smoke management system and approved
management plans wiih fuel load analysis are completed. The approach to
Dobson's non-conformance is a performance-based system. All the pieces to
the puzzle must be completed lo assure the Town that minimum life-safety
issues are addressed.
ACTIONS COMPLETED TO DATE TO IMPROVE BUILDING SAFETY
Additional Egress Widlh. Installtwo (2) additional exit doors at lhe main
entrance (in additional to making sure that the existing pair of 4'-wide doors is
available for egress during events) and two (2) additional exit doors at each of
the upper level side entrances. Two exit doors at the main entrance are added
and simply fill an additional "bay" of curtain wall ("storefront") at each of the upper
side exits with additional exit doors, which would exceed the recommendations
for the side exits which is completed.
Additional Egress Aisles. Add two additional3'-wide stair aisles at each end of
the existing bleacher seating. This improvement has been completed.
Flame Retardant Treatment. Treat the existing wooden ceiling materials above
the paths of egress with an approved flame retardant. I have been told this has
been completed but did not witness the treatment being applied.
lce Rink Barrier Openings. Make additional egress width available through the
barrier around the ice rink for non-ice events such as concerts, etc. Jim Heber,
the manager for the facility, has indicated that this is available through the
installation of the new ice rink barrier, which has much more flexibility than the
old barrier in terms of removing panels to add additional egress width during non-
ice events. Also additional stair width is added to the north side by the use of
movable stairs that are placed during events hosted on the ice surface.
Occupancy Separations. Maintain existing fire-resistive construction and
improve separation of refrigeration room from main public space. This includes
making sure that any storage or mechanical areas are separated from the main
assembly space by 1-hour fire-resistive construction, self-closing-and-latching 1-
hour door assemblies and sealing of penetrations. In addition, the refrigeration
room is to be separated from the main assembly space by 4-hour fire-resistive
walls and two sets of 9O-minute-rated self-closing doors. This was actually to be
accomplished as part of the construction for the addition and remodel project and
should, at this point, be completed.
See ARUP Final Report. This is a very brief summary of some of the
assumptions and recommendations contained in the ARUP Final Report. Please
consult the repon tor more detailed information.

IV. STAFF RECOMMENDATION
ARUP Statf Recommendation:
The ARUP final report actually indicated that, if fuel loads were controlled as
noted in the first section of 'Table | - Summary of Proposed Fire Safety
Measures," up to 3,000 occupants could be accommodated under the usage
scenarios described in the final report. For various reasons, I cannot recommend
that up to 3,000 occupants be permitted at this time. The reasons are described
as follows:
1) The VRD does not have the expertise on their staff to complete a fuel load
assessment or create a management plan in the level of detail required to assure
public safety.
2) There is no assurance that the Town of Vail Fire Department and/or Town of Vail
Building Safety & lnspection Services will have the staffing levels and/or the
expertise to monitor and control fuel load package types and arrangements as
recommended in the ARUP report.
3) lt does not appear that the smoke management system component of the lire
safety improvements, which could be used to provide an additional level of
protection that would offset the deficiencies described above, will be able to be
implemented any time soon.
4) A 4^ exit could be added however the access to this 4th exit would be located on
the mezzanine level thus requiring the occupants to exit through the upper level
located within the smoke-zone. With the addition of a 4tn exit, a smoke-
management system will still be required to maintain an attainable atmosphere
Staff Recommendation:
It is my recommendation that:
1) The maximum occupant load permitted under any conditions, after all fire safety
improvements except the smoke management system and fuel loads
packs/management plans are salisfactorily completed, is limited to no more than
1,500 persons. My professional opinion, in the absence of the smoke
management syslem, a number of .l ,500 persons is appropriate. The staff at
VRD would like to have more than 1,500 people attend events at Dobson. Vail
Fire Department has documentation as to flagrant violations occurring at
Dobson this past winter season
2) Ongoing approvals for "standard" events to occur are based upon standard
layouts and procedures, i.e., the scenarios in the ARUP report. Any departure
from slandard scenarios will require prior case by case reviews and approvals
by the Town of Vail prior to holding events. See attached email from the Vail
Fire Department regarding staff levels. This will also require that VRD staff work
with Town of Vail staff to generate the standard layouts, procedures,
precautions and safeguards ('Tire safety management plans") for each of the
approved scenarios. This has not been done and my recommendation is that
event staff at the VRD does not have the expertise to generate these
management plans.
3) My final recommendation with input from Mr. Michael McGee, Fire Marshall is to
allow a maximum occupant load of 1,500 people, until such time that a smoke-
management system is installed, a complete management plan prepared by
certified event professionals are submitted and approved by the Town including
fuel load pack evaluations. More detailed parameters for fuel loads are
recommended and we should retain either ARUP or another qualified fire
protection engineering firm lo assist.

RE: The Dobson Ice Arena Construction Project - Pedestrian Walk Way, Loading Dock Ramp and Bus
Route Area.
Dear Rory,
The Town of Vail Public Works Department is requiring that the grade between the Bus Route
and the Loading Dock Ramp be corrected to comply with the approved set of building plans. As it exists
today, the grade does not meet the approved plans.
This issue was brought up in late September and a letter was sent to Odell Architects and R.A.
Nelson on October 4, 2001 . Nothing has been done to conect this issue.
The Town of Vail is requiring that all work involved to make the repair must be completed and operational
by December 10,2001 or at TCO, which ever come first
Repair of the brick pavers in this weather may bring up a lot of issu3s and problems in the spring
of 2002. The General Contractor will be responsible for all repairs.
I have included a copy of the letter given to Odell Architects and R.A. Nelson on October 4, 200l.
Ifyou should have any questions, please don't hesitate to call me at 970479-2118
Thank you,

Stanley B. Tumer
Mr. Stanley:
While observing the construction site at the Dobson lce Arena, I have came up with some
concems that I feel are an issue and your attention in solving the matter is required. Keep in mind that no
inspections of the site have been called regarding the Public Works Department, so there is a good chance
that more issues will come up.
l. The Loading Dock area: The grade as it exists today exceeds the Town of Vail of requirements and does
not comply with the approved set ofplans, The issued is from the proposed gate to the edge ofasphalt.
2. I have questioned R.A. Nelson about the new boiler system, and mentioned how it was working and if
the heated portion ofthe bus ramp was operational and working. They referred me to the plumber at the site
where I found out that the bus ramp would not be heated because the new system was design to do that.
I know this issue was brought up in the design stage and the Town of Vail was concemed and addressed
that whatever system was used it must be adapted to melt the roadway and remain operational.
The Town ofVail suggest that Dennis Beaudin, Beaudin-Ganz Mechanical Engineers, review the situation
at the VRD expense.
The Town of Vail will require that Odell Architects and the VRD resolve these issues before any TCO
inspection is issued.
ffyou have any questions, please feel free to me at970479-2198
Thank you,
Leonard Sandoval
