Trinity utilizes the latest technologies including Real Time Kinematic GPS (RTK-GPS) and Robotic Total Stations to provide Topographic Surveys, Flood Elevation Certificates and GIS Mapping.

Construction Services

Because there is more to a project than simply obtaining the necessary permits, Trinity provides Construction Services to our clients. Trinity can help our clients prepare bid documents, solicit Request for Proposals (RFPs) and Request for Information (RFIs), provide engineering estimates, assist in pre-qualifying bidders, and review proposals. Trinity also offers engineering services to contractors who may need to supplement their resources.

Erosion Control – Civil Engineering

Erosion Control is a key component to all projects and is vital to the protection of water quality. All projects that disturb in excess of 1 acre are required to have permit coverage for stormwater discharges from their sites. Other industrial sectors such as gravel pit operation, are required to have coverage under the MSGP program.

Material Testing Services

Trinity provides Material Testing Services. Gravel pit and aggregate suppliers require periodic testing for quality control and to meet project specifications. Contractors may require testing of source materials to meet project specifications. Trinity can sample stockpiles at the source or perform sieve analysis of samples delivered to our testing facility.
