Newark Prudential Office Complex Construction
Site remediation and LSRP services for fast-track construction of a 26-story office building and parking garage on a 2.7-acre downtown Newark city block.
Project Overview
Envicon's team provided site remediation and LSRP services to support the fast-track construction of a new 26-story office building and parking garage for SJP Properties. The 2.7-acre project site encompasses an entire city block located within the downtown section of Newark. The task was to provide site remediation and geotechnical monitoring services synchronized with an expedited construction schedule.
The Challenge
The project site was conflicted by immediately adjacent structures, very old utilities, and neighboring land uses. Three on-site buildings required demolition and contained hazardous materials. Initial site studies indicated several zones of contaminated materials and free product as deep as 32 feet below the existing ground surface.
Our Solution
Working with the project developer and construction manager, Envicon's team performed and submitted expedited remedial investigations and remedial action work plans. The remedial work was divided into phases keyed to the demolition of on-site buildings. Nine underground storage tanks were removed. A GPS-enabled Fuel Fluorescence Detection (FFD) technique was used to specifically delineate the limits of floating product and contaminated soil layers. A 3D model was constructed using FFD and other site investigation results, enabling removal of floating product before excavation and minimizing the volume of soils requiring remediation, resulting in significant cost savings. Envicon's team provided an on-site environmental monitor who operated a perimeter air monitoring system and worked with the contractor and construction manager during remedial construction.
