The precast panels and related components are being produced at High
Concrete’s Denver, Pa., flagship plant. The cladding will feature a utility-size brick veneer finish in two colors. About one third of the panels will be innovative CarbonCast insulated sandwich designs that provide continuous insulation for thermal efficiency. Made with C-GRID carbon fiber shear trusses, the sandwich panels provide fully structural composite action and high insulation value by sandwiching a layer of rigid extruded polystyrene foam.
High Concrete was awarded the $20 million-plus contract by Dulles Transit Partners, LLC of Vienna, Va., project designer, engineer and general contractor. The contract is part of the first phase of the Metropolitan Washington Airports Authority’s (MWAA’s) two-phase, 23-mile extension of the existing Metrorail system from East Falls Church, Va., to Washington Dulles International Airport west to Ashburn, Va. The first phase is underway with efforts concentrated in Tysons Corner, Va., and is scheduled for 2013 completion.
