Our Approach
Integrated Design
Our Civil Engineering team collaborates closely with Diamond’s Structural, Architectural, and Project Management divisions to provide unified design solutions that address site conditions, regulatory requirements, and client goals from day one.
Regulatory Expertise
We maintain strong working relationships with municipal, county, and state authorities, allowing us to navigate permitting efficiently. Our designs comply with all applicable codes, including DEP, DOT, DEC, EPA, and local zoning regulations.
Sustainability in Practice
Every project incorporates sustainable civil design principles from green infrastructure and stormwater reuse to materials efficiency and reduced carbon impact. We believe infrastructure should protect both communities and the environment.
Quality Assurance
Our ISO-aligned Quality Management System ensures that every design package undergoes thorough internal review. QA/QC checkpoints at each design milestone protect clients from costly rework and delays.
