The project scope includes removal of the existing 5,250 square foot hot asphalt membrane roof down to the light weight insulation over steel deck and replacing it with a cold process built up asphalt roof. The station was built in 1981 and received roof rehabilitation in 2005, but its overall condition is poor due to holes in the membrane, pitch pan mastic deterioration, and areas where water is ponding. Leakage is also occurring throughout the facility.
The project scope includes removal of the existing 2,460 square foot Ethylene Propylene Diene Monomer (EPDM) membrane roof on the truck bay area down to the wooden deck and replacing it with a white single ply roof. The roofs over the station and training facility are metal roofs and are not included in this contract. The station was built in 2001, but the roof over the truck bay has visible defects where fasteners have penetrated through the roofing membrane. Leakage is occurring in this area. The masonry was not sealed when the building was constructed and it is beginning to leach calcium deteriorating the concrete block and mortar. The bid included an alternate to seal the masonry and staff is recommending Council include the alternate in this contract to avoid further deterioration.

Leakage is also occurring throughout the gym.
The project scope includes removal of the existing 15,246 square foot two-ply bitumen membrane in hot asphalt roof down to the light weight insulation over concrete (LWIC) roof and replacing it with a cold process built up asphalt roof. The current roof was severely damaged during the April 13th tornado peeling back the membrane allowing water to pool in the layer between the roof deck and the membrane. Leakage is also occurring in the facility.
Santa Fe Depot (flat roof portions) - $48,405
The project scope includes removal of the existing 936 square foot 3 ply hot felt membrane with gravel roof down to the deck and replacing it with a cold process built up asphalt roof.

The current roof is over 20 years old and the overall condition of the roof is poor showing visible defects including deteriorated mastic in pitch pans, weathered and cracked caulk on counter flashing, and open lap seams.
The project scope includes removal of the existing 7,264 square foot Ethylene Propylene Diene Monomer (EPDM) membrane roof down to the concrete and wood deck and replacing it with a white single ply roof. The current roof is over 10 years old and the overall condition of the roof is showing visible defects including holes in the membrane, deteriorated sealant at termination bar, and areas where a wooden block was nailed directly through the membrane. The contractor will coordinate the replacement of this roof with the Director of Sooner Theatre so as not to interfere with the theatre play schedule. The bid also included an alternate to add a 90 foot walkway and guard rail to he east side of the roof and a steel ladder leading to the upper level of the building to meet current Building Code requirements. The alternate also includes reconstructing the roof hatch to accommodate access. Staff is recommending Council include the alternate in this contract to comply with current Building Code requirements and ensure the safety of employees working on the roof.
