Shell scope

One sub. Full shell scope. Zero surprises.

Hand us the shell scope and we handle it start to finish — coordinated, inspected, and turned over clean so your next trade walks onto a ready site. No delays, no surprises.

CMU / Block Walls

Stem walls, block walls by floor, elevator shafts, lintels — laid plumb, straight, and ready for inspection. We coordinate with your structural drawings and flag RFIs before they cost you time.

Concrete Foundations & Footings

Footings, foundations, slab on grade, tie-beams, and elevated decks — formed, poured, and finished to your structural specs. We coordinate inspections so your schedule doesn't slip waiting on the county.

Structural Framing & Rough Carpentry

Floor-by-floor wood framing, trusses, blocking, sheathing, roof decking, and structural connections — built to your drawings and sequenced to your schedule. Turned over square, plumb, and ready for the next trade with no delays.

How we work with GCs

A process built to protect your schedule.

We're built to integrate cleanly into your project — no hand-holding, no schedule surprises. Here's how a typical engagement runs.

STEP 01

Scope Review

Send us your drawings. We review the shell scope, flag any coordination items, and come back with questions — not surprises on site.

STEP 02

Bid Package

You get a clean, itemized bid with scope breakdown and milestone dates tied to your master schedule.

STEP 03

Execute

We mobilize on your start date, work to your schedule, coordinate inspections, and keep the site clean. You'll hear from us — not about problems, about progress.

STEP 04

Turnover

We walk the completed shell with your super, close out our scope, and hand it over ready for the next trade — on the date we committed to.

What GCs tell us matters

No rework. No schedule slippage.

The things that create problems for GCs — failed inspections, messy sites, safety incidents, rework — are the things we've built our operation to eliminate.

We Show Up — Every Day

The crew is on-site when we say we'll be there, working full days start to finish. No no-shows, no ghosting, no chasing us down. When your schedule depends on the shell, showing up isn't optional — it's the whole job.

Zero Incidents Policy

OSHA-compliant practices, proper PPE, and safe rigging on every site. A safety incident on your job is your problem too — we make sure it doesn't happen.

Daily Housekeeping

Materials staged and stacked, debris cleared daily, access paths kept open for other trades. A clean site is a coordinated site — and it reflects on you as the GC.

First-Time Inspection Pass

A civil engineer (EIT) reviews the work against structural drawings at every stage before we call the inspector. Failed inspections cost you days — we don't fail inspections.

Always Responsive & Communicating

We're on-site daily, respond to questions same-day, and keep your team looped in on progress without you asking. No surprises, no radio silence.

Schedule discipline

We run to your schedule — not ours.

Every shell scope we take on gets broken into a detailed activity schedule tied directly to your milestone dates — slab pours, deck dates, inspection holds. As a civil engineer (EIT) and PMP®-certified builder with 20 years in the field, I sequence every pour, inspection, and material delivery so your critical path never waits on us. Every phase of the structural shell gets civil engineer supervision — the block, concrete, and framing are checked against your structural drawings before we call the inspector, not after.
