P-603 Maritime Surveillance System Facility

The high security P-603 project consisted of two new building additions to existing facilities which remained in full operational status and continuing to perform their mission without any unscheduled interruption throughout the construction period while maintaining redundancy of N+1 for critical support systems.

One is a two story building, P-603, with a structural steel frame, split-face CMU / precast concrete exterior wall system, steel H-piles, micro piles, grade beam foundation, on-grade and elevated concrete slabs, pile supported concrete equipment pads and modified bitumen roofing system. The second building is a one-story Central Utility Plant (CUP) of similar construction which houses the mechanical and electrical equipment with the capacity to support the facility completely independent of public utilities. Construction was completed to meet LEED for New Construction 2009.

The new facility includes NOPF training, operations, computer data center, Watch Floor with complex integrated multi-media/LAN control center audio-visual wall system, administrative, maintenance, and watch stander support spaces (toilets, showers and sleeping areas). Specialty systems or equipment include two 2 Mkw emergency generators, uninterruptable power supply (UPS), reconditioned switchgear, two 1500kw substations, fire protection system, raised access flooring, computer room air handlers (CRAH units), and lightning protection. Also included was the design and installation of the audio-visual (A/V) systems, furniture, fixture and equipment (FF&E) package and security (access control and video surveillance) system. The project included the integration of mechanical, data, audio / visual and electrical systems with the existing facility to ensure the new facility and the existing facility operate seamlessly as one facility to complete the mission. Critical to the success of this project was close coordination between SBBCC, NAVFAC, CUS and NOPF during construction.  The new facilities were constructed and turned over in phases on an active site without impacting the critical mission being carried out in the existing facility or new facilities.

The ground floor of this facility and the mechanical and electrical equipment are constructed at elevations of ten feet or greater above mean sea level to keep them above the 100-year flood zone high-water level. Paving and site improvements included parking spaces, loading/unloading and dumpster pads, access road, curbs, sidewalks, landscaping, fencing, signs and demolition of security fence. Electrical utilities include primary and secondary distribution systems, lighting, transformers, and telecommunications infrastructure.

Critical to the success of this project was close coordination with CUS’ and NOPF during construction.  Specifically, the seamless integration of the addition and modifications to the B-469 central plant.  The existing Central Utility Plant (CUP), Building 469, was renovated and enlarged to support of the new addition and serve B-470.  Per the project specifications, N+1 redundancy of all mission critical system was to be maintained during construction to ensure zero impact to the National Security Mission, which was being performed 24/7.

The central heating and cooling plant contain energy efficient equipment (water-cooled heat pump chiller, water-cooled centrifugal chillers, premium efficiency pump/fan motors, etc.) that exceed the ASHRAE 90.1-2010 requirements.  The project required an extension of the existing Direct Digital Control system including a new DDC server.  The DDC network connects B-479, B-469, P-603, and B-464.  All energy systems were commissioned by the contractor’s commissioning authority and performance was verified by the Owner’s acceptance engineer.

Operations and maintenance support information (OMSI) is included in this project. Department of Defense and Department of the Navy principles for high performance and sustainable building requirements were included in the design and construction of this project in accordance with federal laws and Executive Orders. Site preparation included sites clearing, tree removal, import fill, grading and preparation for construction. Special foundation features include piling. The ground floor of this facility and the mechanical and electrical equipment are constructed at elevations of ten feet or greater above mean sea level to keep them above the 100-year flood zone high-water level. Paving and site improvements included parking spaces, loading/unloading and dumpster pads, access road, curbs, sidewalks, landscaping, fencing, signs and demolition of security fence. Electrical utilities include primary and secondary distribution systems, lighting, transformers, and telecommunications infrastructure. Mechanical utilities include water lines, plumbing and plumbing fixtures, sanitary sewer lines, fire protection systems and supply lines. Mechanical utilities include water lines, plumbing and plumbing fixtures, sanitary sewer lines, fire protection systems and supply lines. Facilities are designed to meet the useful service life specified in DoD Unified Facility Criteria. Facilities incorporate features that provide the lowest practical life cycle cost solutions satisfying the facility requirements with the goal of maximizing energy efficiency.
