Project Experience

Civil Engineering Projects

Apex Grid's civil engineers have supported site development across commercial, industrial, and government applications — from small parking lot improvements to full site development packages for new construction.

Scope of Work

Civil scope starts with the site as it is: existing grades, drainage patterns, utilities, easements, and access. We establish what the jurisdiction will ask about — floodplain, setbacks, frontage improvements — then design the grading, stormwater, and utility systems that let the building program work on that ground, whether it is a greenfield pad, an infill redevelopment, or an expansion of an operating site.

Typical Deliverables

A civil package typically includes a grading and drainage plan, stormwater management and detention design with supporting hydrology calculations, water and sewer utility plans, erosion and sediment control, and paving and ADA-accessible route details. Deliverables are sealed by a licensed civil PE and formatted to the jurisdiction's civil plan checklist, so the first submittal is complete.

Codes and Standards

Civil design answers to the local stormwater manual and public works standards first — detention, water quality, and discharge rules are municipal, not national. Layered on those are the building code and local amendments for site work, AASHTO guidance where roadway or turn-lane improvements are involved, ADA and PROWAG criteria for accessible routes, and FEMA floodplain rules where the site touches a mapped flood hazard area.

Coordination and Permitting

Civil sits between everyone: the architect's building footprint, the structural engineer's foundation elevations, the MEP engineer's utility demands, and the utility providers who must accept the connections. We coordinate tap approvals, easement questions, and off-site improvement requirements with the jurisdiction early, because a utility conflict found at plan check is a redesign — and found at construction, it is a delay claim.

Design Risks We Manage

The recurring civil risks are drainage that works on paper but ponds in the field, detention sized for the wrong storm event, and utility inverts that do not clear each other. We manage them with conservative hydrology, invert checks at every crossing, and finished-floor elevations set with freeboard above the design storm — cheap decisions at design time, expensive ones after paving.

Common Questions

Do you design stormwater detention for small sites?
Yes — and small sites are where detention is hardest, because the required volume competes with parking and building area. We use underground detention, oversized pipe storage, and other approaches the jurisdiction allows, sized from the local stormwater manual's release-rate rules.
What does the jurisdiction review in a civil plan set?
Grading, drainage, stormwater calculations, utility connections, erosion control, and accessible routes — usually against a published civil checklist. Our sets are assembled to that checklist, with the hydrology report and utility information included in the first submittal.
