1.2 OBJECTIVES

The primary objective is to ensure the delivery of fully operational vehicle access door systems that meet all safety, accessibility, and performance criteria. This includes:

• Removing and disposing of the six existing, failed door systems, six (6) overhead doors Thermacore® Sectional Steel Door – 592 with LiftMaster H5011L4L.

• Installing six (6) new doors that have a wind rating of at least 95mph/50PSF and an insulation value of R18, white in color.

• Providing automatic openers/lifts, sensors, control units, weather seals, and safety devices for six doors.

• Ensuring all systems are compliant with OSHA, ANSI/DASMA, NFPA 80/105, and ABA/ADA where applicable.

• Door number 101A listed below must have a standard pedestrian door.

• Replacement doors shall match or exceed the insulation and durability rating, with fewer or reconfigured windows (e.g., one row, smaller panes, or insulated glass), using high-performance glazing (e.g., tinted or low-e) to reduce afternoon heat gain—prioritizing energy efficiency while balancing natural light and exterior aesthetics.

• Replacement doors shall not require structural modification to install. Direct replacement only.
