Marvin Gaye Recreation Center
On behalf of the Department of Parks and Recreation, the Department of General Services ordered this project which included the demolition of the existing single-story recreation center and construction of a new recreation center with approximately 10,000 gross square feet.
The new structure was proposed to be located along the south side of Watts Branch Creek and to include a large community room, multi-purpose room, game room, media and reading room, senior room, fitness room and computer lab. The new structure proposed two (2) stories above grade. The main level was proposed to be supported on grade. The second (upper) level (east wing) was proposed to be partially supported on grade and partially supported on columns that make the second floor appear to cantilever out over Watts Branch Creek. Additional improvements were proposed to include shade structures, new lighting facilities, basketball courts, football fields and a baseball field. DMY performed a geotechnical investigation for the new structure and infiltration testing for the planned stormwater management facilities. Due to the potential for significant scour from the 100-year flooding of Watts Branch, a deep foundation system of driven concrete piles was recommended.
Ferebee Hope Recreation Center
The project is located at 3999 8th Street, SE Washington, DC and involved the renovation of an existing playground. The project included the renovation of new playground equipment and furnishing and all the associated work. Storm water management retention was provided using permeable playground surface and underlying gravel layer. The geotechnical information indicated soils with a good infiltration rate.
DMY provided Construction, Electrical and Plumbing inspections to document compliance with local jurisdiction. DMY also performed appropriate laboratory testing on materials proposed for use as fill and backfill. Mr. Abebe Mandefro coordinated technicians and engineers’ efforts under tight schedule constraints to help project completion on time.
Twin Oaks Community Garden
The project is located at 14th Street NW and Upshur Street NW, Washington, D.C. It is bordered by 14th Street NW to the west, Upshur Street NW to the south, recreation center buildings and pool to the north, and multi-level residential buildings to the east. The site slopes downward to the south and west from a topographic high of approximate EL 180 feet to a topographic low of approximate EL 155 feet. The east side of the site is mostly open and vegetated with grass. Wooded areas and dense ground cover are present at the south and west sides of the site. DMY’s specific area of investigation within the park was located on the hill adjacent to the recreation center.
DMY’s scope of services included reviewing the project information provided to us, Drilling SPT borings at five (5) locations to evaluate the subsurface soil and groundwater conditions for the proposed construction, drilling auger probes at five (5) locations to conduct field infiltration testing for potential rain garden locations, evaluating field and laboratory data as well as Performing engineering calculations and analyses and preparing this geotechnical engineering report. DMY also assisted the design team with local engineering requirements as well as concerns unique to the site, which the client was not aware of. This early and active involvement in the project beyond just the geotechnical engineering scope ensured a smooth project design and development process.
