The Crossing at Jamaica Station
Challenges Solved
The Crossing at Jamaica is a large scale mixed-used development which includes a 30-story high-rise tower, 14-story mid-rise tower, parking for 200 vehicles and 45,000 square feet of community and retail space at the ground floor podium level. It was one of the first major developments in the downtown Jamaica area and was a catalyst for the current real estate boom in the area. The site is conveniently located directly across from the LIRR Jamaica Terminal as well as the AirTrain Terminal linking directly to JFK Airport. The site is also sandwiched between the elevated LIRR railway tracks at Jamaica Station south and MTA subway station and tunnel on the west and north.
MRCE performed geotechnical and structural engineering services, including geotechnical investigations, design of micropile foundation, as well as the design of the secant pile and soil mix wall on the north and south side of the site adjacent to the NYCT subway tunnel and LIRR railway. During foundation construction, MRCE developed and implemented an instrumentation construction monitoring program to monitor movement and vibrations at adjacent buildings, LIRR retaining walls, NYCT subway entrance/vents structure and support of excavation systems. MRCE provided resident engineering services that included inspection of the installation of pressure grouted mini-piles, support of excavation systems, and waterproofing for two mixed use towers.
