The project at ZDV ARTCC (Denver) involves installing a new 18-inch high raised access floor system and a Signal Reference Grid (SRG) in the Control Wing Basement, covering approximately 2,982 square feet. The scope includes constructing ADA-compliant ramps and stairs, a new 9-foot-6-inch partition, and a 2-hour rated alcove with a new east door. Extensive demolition of existing ramps, stairs, electrical components, fire alarms, and partitions is required. New installations will include fire stopping, wall-mounted handrails, floor-mounted handrails, new doors and hardware, and various finishes such as rubber wall base, static dissipative rubber tiles, and carpet tiles. Electrical work involves relocating outlets, light switches, and fixtures, as well as providing new wall-mounted light fixtures and exit signs. A crucial aspect is the provision of an SRG under the new raised floor, with all components welded using smokeless exothermic welds, ensuring proper grounding. The project also entails installing a new fire detection alarm and strobe, and reconnecting the key card reader system at the new east door. Pre-construction requirements include stakeholder coordination, compliance with FAA regulations, Work Request Review submission, phased workplan approval, material submittals, and system component verification. Construction activities demand personnel vetting, FAA notification, use of low VOC materials, weekly progress meetings, operational impact mitigation, FAA personnel coordination for electrical work, and strict protection of government property. Waste management, including disposal of asbestos-containing materials and lead, must adhere to state and EOSH procedures. Compliance with EPA, OSHA, Fire Marshal, NFPA, ADA, and all applicable building and electrical codes, including FAA standards, is mandatory.
