News from the BGCAPP Construction Site, April 2015

Published: April 14, 2015 | Category: BGCAPP News, Construction
A Blue Grass worker grinds the edge of a plenum, a pressurized steel housing that acts as a transition point between Munitions Demilitarization Building blast valves and ductwork. An installed plenum can be seen above his head.

A Blue Grass worker grinds the edge of a plenum, a pressurized steel housing that acts as a transition point between Munitions Demilitarization Building blast valves and ductwork. An installed plenum can be seen above his head.

This month’s project update focuses on the plenums currently under construction in the Munitions Demilitarization Building (MDB) at the Blue Grass plant. Plenums are pressurized steel housings that act as the transition point between blast valves and the heating, ventilation and air conditioning (HVAC) ductwork.

In the unlikely event of an explosion, blast valves are designed to contain pressure change. Once complete, plenums will house the blast valves in an airtight cube. This safety precaution is important because the MDB is the plant’s main processing building, which houses the equipment and systems that will disassemble the munitions and remove and neutralize the energetics and chemical agent.

A total of 21 plenums with an average measurement of 6.5 feet and an average weight of two tons each will be installed at the Blue Grass plant.

Assembling, welding and placement of the plenums requires a combined effort from iron workers, who will perform more than 6,100 inches of welding work for each plenum; sheet-metal workers who will connect the plenums to the HVAC ductwork; and painters who will apply protective coatings and fire-proofing material. Next steps for the plenums include balancing the HVAC system to ensure proper air flow throughout the MDB.

Site Construction Progress

Construction: 93 percent complete Systemization: 30 percent complete Construction Turnover: 410 of 585 Quality Data Packages Around the site, ongoing work includes:

  • Interior finish-out of the Entry Control Facility
  • Arrival and installation of Medical Facility and Personnel Maintenance Building modules
  • Systemization efforts focused in Utility, Control and Support and Munitions Demilitarization Buildings
  • Infrastructure work at the Explosive Destruction Technology facility site
  • Continued construction of Supercritical Water Oxidation Processing Building Control Room
  • Installation of commodities such as piping, wiring and cable in most of the main buildings
