Passaic Valley Sewerage Commission – Final Clarifier Walkway PV System
- Owner: Passaic Valley Sewerage Commission (PVSC)
- Client: Advanced Solar Products
- Services: Structural Engineering
MFS Engineers & Surveyors provided professional special inspection services in support of the Final Clarifier Walkway Photovoltaic (PV) Module Ground Mount System project located at the Passaic Valley Sewerage Commission wastewater treatment facility in Newark, New Jersey. Services were performed on behalf of Advanced Solar Products and were based on MFS’ review of project documentation supplied by the client. Project understanding included the construction of a PV ground mount system installed above and along approximately 3,250 linear feet of existing concrete walkways situated between exterior clarifier tanks across the facility site. Construction activities followed design documents prepared by Terrasmart, and special inspections were conducted in accordance with the Statement of Special Inspections.
MFS provided a qualified inspector to perform special inspection services associated structural and aluminum steel erection, and concrete construction components related to installation of the PV ground mount system over the existing walkways. Inspection services were executed in alignment with construction progress to verify compliance with the contract documents and applicable codes and standards. The MFS inspector documented daily field observations through detailed inspection reports that included photographic records of ongoing and completed work activities. Instances of non-conformance identified during inspection activities were recorded and tracked in separate documentation noting the date observed and closure date once corrective actions were completed.
Inspection scheduling was coordinated with the client through preparation of recurring two-week lookahead inspection schedules derived from construction sequencing information provided by others. Inspection frequency varied based on active construction operations throughout the estimated eight- to twelve-month construction duration, with MFS scheduling site presence in response to construction progress updates and photographic documentation furnished by the contractor. Prior to each site visit, MFS obtained Owner authorization and provided advance notice outlining planned inspection activities. Supplemental office-based support was also provided as needed to participate in project meetings, and coordinate with client representatives and facility personnel to support overall project execution.
