We handle commercial and light industrial construction.

Building-level construction in existing commercial and light industrial properties. Office build-outs inside warehouses, restroom additions, production floor reconfigurations, structural openings, and the layout and MEP changes that go with serious building modifications. From single buildings up to programmatic work across multiple properties.

When the work goes deeper than finishes

Building-level construction is its own category of work, requiring a GC who can coordinate permits and engineers, manage structural trades, and keep it all going on a real schedule.

We’ve been running this kind of work for over a decade, with concrete and structural construction at the core of what Ironstone does. The work shows up as office build-outs cut into warehouse shells, restroom additions tied into existing plumbing, production floor reconfigurations that involve rerouting conduit and modifying slabs, and structural openings that change how the space lays out.

You bring us the building and the change you need. We bring the trades, the engineering coordination, the permitting, and the discipline to run it as the construction project it is.

We Know the Challenges Well

Existing buildings keep their secrets. The MEP run that doesn’t match the as-builts, the structural member nobody documented, the conduit that runs where the drawings show open space. The default response is an RFI and a waiting period while the schedule slips. We work the problem on the ground, with our own engineering relationships and trade depth, to keep the schedule moving while the unknowns get resolved.
Building-level work calls on a deep trade bench, including structural steel, concrete cutting and patching, MEP design-assist, fire suppression rerouting, and code-driven life-safety retrofits.
Structural work and MEP changes mean stamped drawings, structural calculations, and permit reviews that can hold a job up for weeks if they’re not actively managed. The contractor has to keep the design team and the building department in motion alongside the build. We coordinate directly with structural engineers, MEP engineers, and the local building department, with the documentation and revision cycle as a planned part of the work.

Common questions on commercial and light industrial work

Do you do ground-up construction?
Generally no. Most commercial ground-up work falls outside what we’re built for, and we’ll be straight with you about that up front. The exception is small industrial buildings, the 10,000 square foot demised shells you see on light industrial parcels. Our concrete and structural background runs deep enough that we can take on ground-up work at that scale. For anything bigger or outside that scope, we’ll point you toward a firm better suited to it.
Opening roofs for new HVAC bays, adding structural walls inside existing shells, cutting load-bearing walls for new circulation, mezzanines and structural steel additions, slab modifications for production floor reconfigurations. We bring structural engineers into the project team early when the work calls for it.
We coordinate directly with structural and MEP engineers from the planning stage forward, and we manage the building department relationship through the permit and inspection cycle. For projects where the design team isn’t already in place, we can bring our regular engineering partners in. The permitting and revision work runs alongside the build as part of the schedule.
Yes. Most building-level work happens in spaces that are still active in some way: tenants in adjacent suites, operations running on different shifts, customers on the ground floor. We scope and sequence around those constraints, with off-hours work and phased construction zones planned into the schedule from the start. If your operation has hard windows or compliance requirements (production downtime limits, specific access patterns), we plan against those before mobilization.
