Deerfield Road Bridge (CR 540) over the Cohansey River
Services:
- Survey & Wetlands Delineation
- Bridge Alternative Analysis
- Permitting
- Hydrology/Hydraulic Analysis
- Preliminary & Final Plans
- Cost Estimate
- ROW Plans & Legal Descriptions
The project included widening to 40 feet by replacement of the existing 2-span reinforced concrete rigid frame structure. The bridge was constructed in 1924, and the existing deck geometry was inadequate per previous studies. The existing approach guiderail and concrete barrier curb across the bridge was also substandard.
CES was chosen by Cumberland County to provide services for the project that included surveying, preliminary design, alternative studies, final design, permitting, and bid documents for the bridge replacement.
Tomlinson-Mill Dam, NJ Dam #31-87
Township of Evesham, Burlington County, NJ – CES preformed an analysis to determine existing runoff, inundation mapping, and appropriate spillway design storm. The project included preparation of inundation maps suitable for inclusion to the dam’s Emergency Action Plan, and performing bathymetric cross sections of each existing pond to estimate storage volumes of the reservoir’s NJDEP/Dam Safety Flood Control (DSFC) coordination. CES coordinated initial versions of the H&H analysis through NJDEP/DSFC for confirmation of completeness and adequateness of the study and reports, and all review comments were addressed for final NJDEP approval. CES also developed an Operation and Maintenance Manual for the dam.
Cumberland County Multiple Dam Inspections
Dam structures undergo routine inspections as required by the State of New Jersey. CES was chosen by Cumberland County to provide Formal Inspection Reports for several County-owned dams.
These studies included inspection of existing bank slopes and crests, surface erosion, vegetative intrusion, and review of abutments, spillway structures, and exit channel conditions.
Most dams are older and come with culvert or bridge structured roads above. CES documented pavement conditions in these cases.
CES reviewed the latest Emergency Action Plans and Operation and Maintenance manuals to ensure compliance with the latest safety requirements.

Wadsworth Lake Dam Removal Permit
Washington Township, Gloucester County, NJ – CES provided engineering services to prepare a New Jersey Dam Safety Permit Application and supporting documents for the removal (breach) of the Wadsworth Dam, currently listed with the NJDEP Dam Safety Section as an ‘unsafe’ high hazard dam.
A previously prepared Hydrologic Analysis for upstream Kandle Lake Dam was used to obtain inflow hydrographs and routings to show the downstream impact of the Wadsworth Dam removal. Also, the Gloucester and Camden County Soil Conservation Districts previously performed an assessment and characterization of the Upper Mantua Creek, which was used to develop inflow data from the watershed. This analysis also included information on the Wadsworth Dam and will also be used to develop downstream information and modeling of the dam removal. Last, NJDOT recently performing road improvements to the Delsea Drive and East Holly intersection area. As part of its design and permitting process, a hydrologic and hydraulic analysis was performed to size the bridge replacements under Delsea Drive and East Holly. All of these studies will be included in the Wadsworth Dam removal calculations and stabilization design.

Kennedy Health – Cherry Hill Replacement Hospital
Cherry Hill Township, Camden County, NJ – In 2017, Kennedy Health’s Cherry Hill Division completed a magnificent Atrium Entrance and five-story medical office building (MOB) at the Cherry Hill Hospital Campus. Phase II of the plan recently received preliminary and final planning board approval.
CES was honored to design, provide permitting services and Planning Board testimony for a six-story replacement hospital building that will join the new Atrium/MOB. The project is approximately 250,000 square feet with a helicopter pad on the roof. It will include a new surgical suite, medical lab and support facilities, and move to a private hospital bed model. New cherry trees were added to the site and County Road landscaping plans to reflect Cherry Hill Townships tradition.

Scotland Run Golf Course
Client: Scotland Run Golf Course
Services:
- Surveying
- Site Planning using Stephen Kay’s Design
- Storm Drainage
- Clubhouse Site Plan and Parking
- County Road Widening
- Water and Sewer Main Extensions
Monroe Township, Gloucester County, NJ – Designed by Golf Course Architect Stephen Kay, Scotland Run is one of the premier golf courses in New Jersey. This course was reclaimed from a past gravel pit and transformed into a unique course with three different looks: wooded, open field (a former farm field), and links (former gravel pit).
The 26,000 square feet clubhouse has one of the nicest restaurants and banquet facilities in the region. CES designed a storm water management system that avoided long and costly environmental permits, provided site planning for the clubhouse, and obtained County road permits for over a half mile of County road.
North Camden Water Pump Station
- Design, Specification
- Bidding Assistance
- Construction Surveillance
- Construction Management and Administration
Mechanical improvements included replacement of split case centrifugal pumps. Old valves and pneumatically operated switches were replaced with new solid state electric operators. Additionally, CES professionals upgraded the adjacent five million gallon at-grade storage tank’s cathodic protection system, monitoring system, and the City’s SCADA system.
Electrical improvements included retrofitting the entire interior electrical system, including MCC, control panel and telemetering, replacing interior wiring, conduits and grounding, design of a new 480V – 3 phase natural gas standby generator with an automatic transfer switch, and replacement of all interior and exterior lighting.
Radium Removal Treatment Wells #14 & #15
Services:
- Survey
- Site Plan
- Building Layout
- Approvals
- Soil Erosion Permitting
- System Design
- Construction Management
- Contract Administration
CES coordinated and designed the necessary treatment, electrical, and instrumentation systems. CES and WRT coordinated with Aqua NJ the exact SCADA system requirements. The design included hardware requirements for the SCADA system as well as the I/O wiring required to and from the various field devices.
CES performed an hydraulic review of the well pumps and the pressure drops from each system and recommended pump upgrades accordingly. We also provided all contract documentation and drawings for bidding purposes, and provided construction management services for both treatment plants. The building design consisted of a split faced masonry wall with masonry “A” frame wood roof construction.
Painting and Upgrades to Three Municipal Water Storage Tanks
Services:
- Engineering Design and Specifications
- Bidding Assistance

CES provided construction management services for the sand blasting and painting of the three city-owned potable water storage tanks. The storage facilities consist of two two-million gallon hydropillars and a five-million gallon ground level tank. Services included field observation of the blasting and painting activities, conducting the pre-construction meeting, review of shop drawings and contractor payment requests, issuing clarifications during construction, coordination with the client and contractor, conducting wage rate interviews, and more.
The City also awarded two change orders to CES’s contract to perform engineering design and construction management services for the rehabilitation of the altitude valves at the two hydropillars and the replacement/upgrade of the city’s SCADA data collection system for both the potable water and sanitary sewer facilities.
