Ted Stevens Anchorage International Airport, Seismic and Security Upgrades PDC provided mechanical and electrical design services for the $145 million multi-phased renovation to the South Terminal facility. The project was constructed under a Construction Management at Risk delivery method allowing PDC and design team working with the General and Sub Contractors to bring the project within budgets. The mechanical and electrical systems were part of a comprehensive commissioning process. Owner requested additions to the project, including interior remodel of A Concourse, were handled efficiently during construction in conjunction with the subcontractors to maintain overall project completion dates. The mechanical portion of the project includes extensive upgrades to the heating, cooling, ventilation, and control systems including the replacement of six mechanical rooms and significant renovations in three more. Modifications were made to the central heating and chiller plants, including a new boiler and cooling tower. Worked closely with Airport Facilities throughout project to understand existing systems as well as review and approval of proposed new systems. A study was completed early in the project that looked into the use of well water cooling but was not implemented due to first cost. Fire suppression systems included an electric fire pump and wet, and dry and dry pendant on wet sprinkler protection systems.
