As the prime consultant for NYCDDC, SI Engineering, P.C. (SIE) provided resident engineering inspection services for the construction of storm and sanitary sewers on 204th Street in Queens to help prevent chronic flooding. The area of work stretched between the Dead End and 42nd Avenue to 42nd Avenue between 204th Street and Clearview Expressway.
Our team inspected the installation of two 24” Reinforced Concrete Pipe (RCP), 18”, 15”, and 10” Extra Strength Vitrified Pipes (ESVP), and 13 total catch basins and connecting an existing 8” sanitary sewer to a new manhole and a new 24” storm sewer to an existing drop pipe. Project work also included curbs, manholes, roadway resurfacing, and tree planting.
The plan’s original design had an incorrect slope for an elevation on 42nd Avenue and Clearview Expressway, which was corrected after our REI team instructed the contractor to survey the slope, preventing any delays to the project’s completion.
SIE was involved in all construction operations of the contractor for conformance with the contract plans, specifications, and proposals. SIE’s staff was responsible for the review of the contractor’s daily maintenance and protection of traffic set ups, measuring the quantities of the contractor’s daily activities, tracking equipment utilization and workers by job classification, preparing daily inspector reports, and reviewing overall job site safety as per NYCDDC standards and methodology. Seamless coordination with agencies and the stakeholder was in constant practice by SIE’s team to successfully complete the project on time and within budget.
