Queens Plaza Redevelopment
In addition to temporary excavation support, foundation design, and construction inspection services for three new high-rise buildings, MRCE provided instrumentation and monitoring of sensitive NYC Transit structures including a substation, a tunnel, an elevated viaduct, and a bridge abutment. MRCE designed and installed automated instrumentation to monitor vibrations and movement of adjacent structures during installation of soldier and secant piles at the site perimeter. Due to the size of the development and the presence of the substation building, several automated motorized total stations were utilized to monitor deformations continuously. All instruments had remote communication for automated “real time” data uploads to the MRCE Instrumentation website. The instrumentation portal was viewed on mobile devices by the owner, contractor, and site project personnel.
