The Terminal 1 Paging System Upgrade project perfectly illustrates MHC’s ability to deliver an massive square footage renovation project, within an occupied facility, for a Nevada Public Works agency, under the CMAR delivery method.
The original scope of work for the construction phase included: Installing a new paging system throughout the Terminal 1 and Main-Terminal that integrated with a previously installed paging system at Terminal 3 and D-Gates; Removing paging system from existing Life-Safety devices; Installing Security Cameras throughout Terminal 1, Central Terminal, Control Towers, and select Airside Locations; and Installing Access-Control Devices throughout Terminal 1 & Central Terminal. The project was broken up into five (5) phases starting at A-Gates’ Cluster Building 4 (CB4), and finishing at C-Gates with 350 calendar days allowed for project completion.
Starting the project in the unoccupied CB4 gave the field crews and project team time to evaluate and refine execution of work before proceeding into occupied areas of the airport where access and work would be restricted. Crews developed efficient work processes whereas ceiling components were removed, new paging system speakers installed, speakers and ambient noise sensors wired, ceiling components reinstalled, conduit and data wire installed with home-runs back to assigned IDF/MDF closets, installing head-end equipment in the IDF/MDF closets, testing and commissioning the system, and training personnel for immediate use. Ancillary work also included installing AC split units in the new paging system equipment rooms, access-control devices (door card readers), and security cameras.
The installation of the paging system in B-Gates required other means to hang speakers in the cluster building due to test results showing levels of asbestos in the ceiling. This required a high-level of planning and coordination with the Airport Central Command, since Airlines had to be moved to non-occupied gates while crews in scissor-lifts on the Tarmac removed glazing and drilled holes through the mullions to route conduit for new speakers. This work required careful consideration, planning, and execution to ensure that plane traffic was not hindered and all debris (metal shavings) were removed from the Tarmac to prevent any damage to aircraft.
Martin-Harris Construction was the AGC Safe Site Award in August 2013 for the $7.5 million upgrade to McCarran International Airport’s Terminal One. Completed in September, the project improved the airport paging system over a 5 million square foot area while also enhancing security cameras and access door controls. The work additionally entailed miscellaneous tenant improvements. Martin-Harris had 50 people on site during the peak of construction activity, recording 34,000 man-hours without a lost-time incident. Construction took place inside a highly restricted and controlled area with 24-hour operations.
