Apex Grid provides full multi-discipline engineering for multifamily developments — structural framing, MEP systems, civil site development, and geotechnical investigations — as a coordinated package or as individual disciplines.
Discuss Your ProjectThis project category involves: Structural Engineering, MEP Engineering, Civil Engineering. Apex Grid provides these as coordinated multi-discipline services or as individual discipline engagements depending on project scope.
Send Us Your ProjectMultifamily scope is repetition with variation: the same unit types stacked and repeated, but every stack carries structure, plumbing, ventilation, and egress that must land in the same place on every floor. We engineer the full package — wood-frame or podium structure, unit and common-area MEP, site civil, and the geotechnical basis — as one coordinated set, because a shaft moved on floor three is a change on every floor.
Deliverables include structural framing plans and calculations for the wood, steel, or concrete podium system; MEP plans covering unit HVAC, plumbing risers, and electrical distribution and service sizing; amenity and common-area systems; and the civil and geotechnical packages for the site. Sets are sealed per discipline and coordinated so unit layouts, shafts, and structure agree across the whole building.
Multifamily design works under the IBC for the building and the energy and ventilation codes that govern the units: the IECC or the adopted state energy code, ASHRAE 62.2 for dwelling-unit ventilation, NFPA 13 or 13R sprinkler criteria, and accessibility under the Fair Housing Act and local amendments. Sound and fire separation between units — rated assemblies and corridor requirements — shape the details from the first floor plan.
The architect's unit plans drive everything, and our coordination job is keeping structure, shafts, and systems inside them as the design develops. We coordinate early on podium drainage and utility entries, on meter banks and EV charging counts for the electrical service, and on the accessibility and energy documentation the permit set must carry — the items plan reviewers ask for first.
The classic multifamily risks are plumbing risers that miss their stacks, dryer and bath exhaust routes that cannot be built as drawn, and podium transfer conditions discovered late. We manage them with stacked wet-wall discipline from schematic design, exhaust routing checked against the framing direction, and the podium transfer structure designed before the framing above it is detailed.
We respond within one business day with a fee proposal. No project too large or too small.
