Office Construction Overview
An office build-out lives or dies on schedule certainty. Every day past your lease commencement date is rent you pay on space you can't occupy, so we build the construction schedule backward from your move-in date and hold it with fixed pricing, a single point of contact and daily on-site supervision.
Our office construction teams handle full interior fit-outs: demolition, metal stud framing and drywall partitions, glass front offices, acoustic and open ceilings, electrical and data rough-in, HVAC distribution and rebalancing, sprinkler relocation, millwork, flooring, paint and final furniture coordination. We manage landlord approvals, building department filings, COI requirements, freight elevator scheduling and after-hours work rules in Class-A buildings.
We work directly with owners, tenants, brokers, architects and workplace strategists — from a 2,500 SF suite refresh to a 60,000 SF multi-floor headquarters relocation.

How We Deliver Office Projects
The steps below are specific to office work — the details that keep these projects on schedule and out of trouble.
Landlord & Building Review
We pull the building's alteration rules, tenant design criteria and insurance requirements first, so filings and COIs never stall your start date.
Test Fit & Fixed Budget
Test fit, finish selections and a line-item budget locked before demo — priced against the actual base-building conditions, not assumptions.
Filing & After-Hours Plan
DOB/permit filings plus an after-hours demolition and noisy-work schedule agreed with building management and neighboring tenants.
MEP-First Sequencing
Ceiling MEP, sprinkler relocation, low-voltage and HVAC distribution roughed and inspected before drywall closes.
Furniture, IT & Move-In
We coordinate the furniture, AV and IT vendors into the final two weeks and hand over a punched, cleaned suite ready for day-one occupancy.

Office Construction FAQs
How long does an office build-out take?
Most 5,000–15,000 SF office build-outs run 10–16 weeks from permit, depending on long-lead MEP equipment and landlord approvals. We give you a locked schedule before we mobilize.
Do you work in occupied office space?
Yes. We phase work floor by floor or zone by zone, run noisy trades after hours, and maintain negative-air dust control so your team keeps working.
Do you handle permits and landlord approvals?
We manage the full filing process, landlord design review, COIs and building rules compliance as part of the contract.
