As a subconsultant, SI Engineering, P.C. (SIE) provided construction inspection services for this FEMA-funded contract for the Passaic Valley Sewerage Commission (PVSC). The goal of the project was to restore the Newark Bay Wastewater Treatment Plant to a reliable state of operation and improve resiliency following damage from Superstorm Sandy. The scope involved restoring equipment and systems while ensuring maintenance of plant operations, as well as making the plant resilient to future storm surges and power disruptions. Key infrastructure elements included the power plant, floodwall at the plant’s perimeter, and pumping stations.
SIE’s responsibilities on this project included observing steel pipe piling operations, structural reinforced concrete construction, and installation of storm sewer systems. Specific tasks included inspection of pile driving operations, including steel pipe piles, rock socketed caisson piles, and sheet piles. SIE inspected the installation of pile rebar cage and pouring of 5,000 PSI concrete / grout into piles, ensuring that the concrete meets required air, temperature, and slump specifications. The work also included inspection of pile cap steel reinforcements and pouring of pile cap for the floodwall foundation, as well as inspecting the reinforcement and pouring of the concrete floodwall and piers. SIE’s staff read and interpreted project drawings, specifications, and shop drawings and provided daily reports of activities.
