Keller Engineers’ responsibilities included providing design, post design (including shop drawing/catalog cut reviews), and construction inspection support to the County.
This project addressed multiple site conditions, including:
- Tree and debris removal from spillway boxes, stream bed, sidewalks, sheet pile wall, and embankments.
- Erosion control measures through the use of grouted and ungrouped riprap, fill, matting, topsoil, and seed mixes.
- Water seepage by pressure injection of concrete cracks.
- Repairs to deteriorating or damaged gabion baskets.
- Coordination with NJDOT for lane closures along Route 30.
- Address deterioration and erosion of Dam structures following submission of PS&E documents; Atco Lake Dam required a Change of Plan to stabilize advanced deterioration.
Project Uniqueness/Challenges:
- The delivery of the contract documents, including plans, details, specifications/ bid documents, and Engineers Estimate was accelerated so the project could be advertised for construction two months after we received Notice to Proceed.
- Extensive coordination with NJDEP’s Dam Safety & Flood Control group was necessary in order to obtain their “buy-in” and project sign off.
- The pressure injection grout operation at the Evans Pond Dam required unique expertise.
- The grouted rip rap operations conducted at Evans Pond and Haddon Lake Dams followed a thoroughly orchestrated work plan.
