FIRE SUPPRESSION UPGRADES
The Numismatic Gallery, a Design/Bid/Build Project, entailed the Fit Out of a vanilla space to create this new Gallery/Exhibit. The project included fire suppression, electrical, mechanical, drywall, paint, suspended ceiling and carpentry trades. The project was performed at the Museum of American History on the National Mall. The gallery that was renovated is used for a historic coin (numismatic) collection. The coin collection is priceless. The fire suppression system installed was designed with the preservation of the coin collection as a top priority should there be an event. Coordination with the museum curators, as well as museum security, was critical, given the nature of the work, and the fact the that the remainder of the museum remained operational during construction.
ENERGY MANAGEMENT SYSTEMS REPLACEMENT
This Design/Build Project involved replacing the existing proprietary Siemens Energy Manage-ment System at the NAC DHS Complex with an Open LonWorks EMS with LNS Web Based Graphical User Interface. We are replacing the Siemens Control network with new Open Lon standard CEA-079 TP/FT-10 network through an IP network. This includes all wiring, routers and panels, a new EMS Server with LNS enterprise Web Based Graphical User Interface, and LNS Web Based Graphical (Web Alliance) User Interface in each building, these will include graphic pages, alarms, trending and Scheduling. We are also providing design of OSP optical fiber cable to support 9 buildings, and installing the Network Switch to support those buildings, and installing the fiber switches, fiber, fiber connections, patch panels, and racks for each building.
National Building Museum - Condenser
Water Pumps & Filter
In this Design/Bid/Build Project, Severn Associates replaced the existing condenser water system with six new condenser water pumps. The work required the electrical disconnect of each existing pump, and cleaning of sediment out of the basin, while allowing for the continuous operation of the condenser water system. Concurrently, with the pump work, we replaced the filter with a new Vortisand filter unit.
