TMG Construction provided the design-build upgrade of Access Control Points 3 and 4 at a secure facility in New Cumberland, Pennsylvania. The project involves the design and construction of an integrated system of active and passive vehicle barriers at two entry control points to prevent threat vehicles from breaching a secured compound perimeter.
The overall project is being performed in two phases, one for each of the two Access Control Points (ACPs), which are roughly a mile apart. ACP 3 is further divided into six phases, while ACP 4 is divided into three phases. Mobilization for each point is dependent on approval of environmental permits from the local regulator jurisdictions. The scope for both points includes new drainage structures, asphalt pavement, canopies over truck and automobile entrance and inspection facilities, traffic control buildings, fencing lighting, communications, new prefabricated guard booths, intrusion detection and closed circuit television systems, and under-vehicle surveillance systems, in addition to electrical service upgrades, emergency generators and control systems to activate and monitor the new vehicle barriers.
To accelerate the submittal process, the project team segregated the civil scope as a separate submittal package. This allowed the team to submit an early 100% design to regulatory agencies to obtain permits at the same time the architectural and MEP permits are expected to be issued – lopping as much as three months off the schedule.
