Description of Project
The Sebastian Vail Penthouse Unit 507 (Project) is located within the existing development known as “The
Sebastian” in Vail Colorado. Initial project development of the unfinished unit was mostly completed
around 2006. The proposed building work consists of expansion and completion of the currently
unfinished existing 2-level penthouse unit. This is the top two floors of the 5-story building. New
construction will include, but not be limited to installation of new building and roof structure, new exterior
balconies, exterior envelope and finish materials, interior walls and finishes, mechanical, plumbing and
electrical systems. Site preparation includes removal of existing roof structure in the penthouse area and
modification of some lower level structural elements, which would require a boom crane on private
property adjacent to the ROW, and a construction staging area in the I-70 Right of Way (ROW). The
overall construction duration would be approximately 4-6 months, and it is desirable to begin construction
by May 1, 2014

Analysis of Alternatives
Please see attached options 1, 2a, and 2b
The contractor evaluated several types of cranes to find an option that did not encroach into the ROW at
ground level, and was able to identify an option that keeps the crane base on private property. All options
presented show this. The contractor evaluated several types of crane boom configurations to minimize the
area of boom overhang the ROW. Option 1 shows a full 360-degree free-swinging boom. Option 2a
shows a restricted boom that greatly reduces ROW overhang.
The contractor also evaluated several options for staging of materials transfer to/from the site and trucks.
The contractor will likely utilize a self-erecting tower crane and will either use the existing Sebastian
loading dock, a temporary service drive or temporary 1-lane diversions along S Frontage Road E for
staging/deliveries.
• Option 1 keeps the existing sidewalk in place, but would require closure on the outside eastbound
through lane of the South Frontage Road in order to provide the materials transfer area. If this
option is used, the contractor will arrange on time deliveries with roughly 1-3 hour windows.
• Option 2a and 2b show the materials transfer area close to the building in the location of existing
sidewalk. This would need to be restored near the end of construction. There would not be any
lane closures on the South Frontage Road.
