HERBERT C. HOOVER BUILDING MODERNIZATION (PHASE 2)
Facade cleaning and restoration
By: Chris Chacey, Grunley Assistant Superintendent
The Gilbane/Grunley Joint Venture (GGJV) is in the midst of the largest phase – Phase 2 - of construction of the multi-phased, multi-year modernization of the Herbert C. Hoover Building.
Current Status
On the interior of the building, ceiling grid is going up and walls are being framed. New door frames are being set and masonry walls and repairs are wrapping up, allowing plaster repairs to shift into high gear. Approximately 75% of the new MEP systems are roughed-in. Historic window restoration and operability work is wrapping up as new windows are being installed. The basement ground works are approximately 50% complete and new sump pits are being set in the southern corners of the building.
Construction of the new Electrical Equipment Enclosure (EEE) is 95% complete. With all of the floor slabs placed and main equipment set, interior block walls are built and spray-on intumescent fireproofing has been applied. In the chiller plant, the chillers were craned over the building and have been set on their pads. The plant’s steel structure and concrete roof slab have been completed and the roof has been dried in.
On the exterior of the building, GGJV is continuing with the cleaning and restoration on the 14th Street facade as well as in Courtyards 5 and 6. Installation of the new exterior fuel tank is about to start, with the tank to be set in the next two to three weeks.
What's Next?
Over the next few months GGJV is expecting to start wall close-ins and floor leveling. We anticipate having PEPCO pull their new power lines to the EEE, supplying the jobsite with a new power source. The piping for the new chiller plant’s motor control centers and vertical fan drives will also be completed. The new site wet utilities are on hold and are anticipated to start next spring. Exterior cleaning and point-up will continue progressing north along 14th Street towards Pennsylvania Avenue with completion estimated for September of 2012. Date Posted: October 26, 2011
