Buzzard Point HAZMAT/Demolition (DC United Stadium Site)
The District of Columbia government and the owners of the D.C. United Soccer franchise recently entered into an agreement to build a new stadium for the team in the Buzzard Point area of Southwest DC. The new stadium will be completed by 2018.
The site contains four structures along First Street, SW. A previous HAZMAT survey identified asbestos-containing materials, lead paint contamination, and traces of other hazardous material including PCB’s, mercury, lead-acid batteries, as well as Freon and other refrigerants.
Under the agreement between the City and the developers, the City is required to clear the site and remove any and all hazardous materials. The City contracted with a firm to abate the asbestos during demolition of existing buildings and the Department of General Services hired DMY Capitol to monitor the abatement and perform clearance testing to get close outs to obtain the raze permits necessary to demolish the buildings and get the site ready for construction.
DMY’s contract required the services of an Industrial Hygienist to perform the following:
- Daily verification of all workers and supervisor documentation
- Ambient air sampling inside all regulated work areas
- Air sampling when lead-containing components are disturbed
- Documentation via digital photos of work areas, containments and work progress during the project
- Final visual inspections of all abatement areas
- Sampling and testing of any suspect asbestos-containing materials
- Issuing a reports at the conclusion of the abatement and demolition phases.
The Equitable Building
The equitable building was an existing historically protected two-story commercial building with an entry atrium space located in the Chinatown district, between 9th and 10th on F Street NW. The project proposed demolition of the rear tow story structure to make way for a seven-story office tower addition with mechanical penthouse. Three levels of retail were proposed for the basement to second floor levels, while the remaining floors were designated for office use. The building is 100’ tall with a total area of 23,609 GSF. Structural steel framing and concrete metal deck were used for the rear structure. The north and south facades consisted of aluminum curtain wall and insulated metal panels, while the east and west party walls were of masonry construction with a metal panel rain screen.
DMY Capitol engineers performed a series of geotechnical work including concrete field testing, soils compaction testing, foundation testing, reinforcing steel observation as well as masonry observation. DMY issues daily field reports and laboratory testing reports as part of our services. The reports of our services are reviewed by the Professional Engineer and then distribute electronically to all pertinent parties. All the data are managed through our proprietary web-based system DMY Manger®. The electronic system has improved our efficiency significantly and our clients
The project consisted of a renovation of the Hotel Hive, located at 2224 F. Street, NW in Washington, DC. The hotel is a five-level development with four levels about grade.
DMY Capitol, LLC provided Third Party Inspections on this project and offered inspection during the construction of the following:
- New enclosed exit stairs
- New guest room bathrooms in existing sleeping units
- Existing open exit stairs enclosure
- New lounge/bar and food service area
- New accessible entrance
DMY provided Third Party Code Compliance Inspections for building, plumbing, mechanical, electrical, fire protection and elevators.
Trapese School Of New York
This project consisted of two trapeze facilities, located within 15 feet of each other. The largest of the two facilities covered an area of approximately 12,000 square feet and was proposed be an open trapeze facility. The smaller facility located immediately east of the larger one, covered an area of approximately 6,600 square feet and was proposed to be a covered metal-framed structure that would have allowed use during inclement weather. Two potential infiltration systems were proposed be developed on the site. We understood that the new facility will use shallow concrete piers below grade to anchor the guy wires for the new trapeze structure. DMY performed a geotechnical investigation which include borings and laboratory testing. In addition, DMY performed infiltration testing for the new stormwater management facilities.
