The project consisted of the construction of a 27-ft by 25-ft precast concrete building to house an existing generator, battery backup system and various other critical communications equipment at the top of Buffalo Pass, a remote mountain location at 10,600’ elevation near Steamboat Springs, Colorado. The building was fabricated offsite in three separate concrete building modules with a two-story sheltered entry. The three segments were delivered and set into place on the new reinforced concrete foundation with a large mobile crane. In order to prepare for the delivery of the building, other work on the project included installation of a new building grounding system, trenching and grading, replacement of the existing liquid petroleum gas system, and installation of a new waveguide medium voltage cable bridge. Once the buildings modules were set in place and anchored, finishing details included installation of miscellaneous metalwork, insulation and finishes, hollow metal doors and frames, overhead cable ladder, single-ply membrane roofing, HVAC and electrical systems. Coordinating the delivery and installation of all of the many components of this project presented a unique challenge due to the fact that the jobsite and access roads are covered with up to 15’ of snow approximately 10 months each year.
