Change of Occupancy / Use
Retail to assembly, office to medical, warehouse to manufacturing. Use changes can shift the risk category and trigger structural upgrades — we identify the trigger and scope the upgrade.
PE-stamped structural design for tenant improvement projects — change of use, openings in shear and bearing walls, mezzanines, rooftop equipment, and demolition coordination. Engineer-led, contractor-friendly.
Most tenant improvements are architectural — but the few that touch structure are where engineering judgment matters most.
Retail to assembly, office to medical, warehouse to manufacturing. Use changes can shift the risk category and trigger structural upgrades — we identify the trigger and scope the upgrade.
New doors, windows, or openings cut into shear walls, bearing walls, or wood-frame diaphragms. Header design, drag-strut continuity, and shear-wall capacity re-checked.
New mezzanines for retail, warehouse, and office TI. Foundation impact, column loads, lateral system, and code-compliance review — including mezzanine area limits.
Added HVAC, solar, kitchen exhaust, or telecom equipment. Roof framing capacity, anchorage design, and structural support pad design.
TI schedules are tight. We turn structural reviews quickly and stay reachable for RFIs during construction.
Review the architect's TI plans against the existing structural drawings. Identify scope items that need engineering attention.
Confirm the items in scope, propose any additional investigation (e.g. measured documentation of unrecorded walls), and lock in fee. One-business-day turnaround.
Structural sheets coordinated with the architect's plans. Includes headers, posts, drag-strut details, anchorage, and any retrofit triggered by use change.
Plan-check responses, contractor RFIs, and field clarifications. Site visits when the structural scope warrants it.
Use changes that increase risk category, significant alterations to the lateral system, or expansion above the CBC alteration thresholds can trigger evaluation under existing-building provisions. We flag triggers early so they don't derail the schedule.
Yes. Most TI projects involve direct coordination with the architect of record and the GC. Issue tracking and RFI response stay with us so the design intent is preserved.
Simple TI structural scopes: 1–2 weeks. Mezzanines and major openings: 2–4 weeks.
We handle the structural scope. Energy code (Title 24 Part 6) is the architect's scope; we coordinate where structural and Title 24 interact (insulation, openings).
