Commercial tenant improvements (TIs) modify an interior to fit your operations without changing the building shell. ISG handles demolition, layout and framing, drywall and acoustic assemblies, doors and hardware, millwork coordination, flooring, paint, and specialties. We coordinate MEP trades (mechanical, electrical, plumbing), relocate diffusers, add lighting and power, and address life safety: fire separation, firestopping, exit signage, and device locations. We work from stamped drawings, manage permits and inspections, and stay aligned with landlord criteria and timelines. Whether it’s reconfiguring an office, building exam rooms, or refreshing retail, we sequence work to minimize downtime and deliver a clean, ready-for-furniture space.
