What actually sets the date

Build-outs rarely open late because of construction.

When a build-out misses its opening date, the cause is usually one of three things, and construction speed is almost never the one. Commercial plan review takes weeks that nobody put on the calendar. A long-lead item, mechanical equipment or casework, was ordered after pricing instead of during. Or the lease turned out to deliver less than everyone assumed, and the scope grew after the schedule was set.

We plan against all three. The review window goes into the schedule from day one, the long-lead items get identified during pricing, and we read your lease before we price so the scope reflects what the landlord is actually giving you. Casework comes out of our own Wichita shop, which takes one of the worst lead times off the critical path entirely.

If your project is ground-up rather than a build-out, that is a different timeline and a different conversation; see our commercial construction services. And if someone else is building it, we also serve as owner's representative.

Who we build for

Spaces we build out.

Office and professional
Open plans, private offices, conference rooms, and breakrooms, with casework from our own shop so the reception desk is not a six week lead item.
Retail and showroom
Storefronts, fixtures, flooring, and lighting built around an opening date that is usually already advertised.
Medical and dental
Build-outs with the plumbing, power, and finish requirements clinical space demands, sequenced so inspections do not stall the schedule.
Restaurant and food service
Kitchens, hoods, grease interceptors, and dining rooms, where the mechanical and health requirements drive everything else.
Occupied space renovation
Reworking space while your people keep working in it, phased around your hours instead of ours.

Why JAKS

What one contractor gets you.

Casework from our own shop
Reception desks, breakroom cabinetry, and built-in casework are among the longest-lead items in a build-out. Ours come off our own floor, so they land when the schedule needs them.
The plan review window is planned for
Commercial plan review is the single most common reason a build-out opens late. We schedule around it from day one instead of treating it as a surprise.
One contract, every trade
Mechanical, electrical, plumbing, framing, finishes, doors, and hardware under one general contractor. You are not refereeing between subs while trying to open a business.
We work around your operations
For occupied renovations, the phasing and the hours are part of the plan, not something worked out after the noise starts.

How it works

Lease walk to open doors.

01
Walk the space with your lease
What the landlord is delivering, what the allowance covers, and what the space actually needs are three different things. We reconcile them before pricing.
02
Pricing and scope
A written scope with real numbers, so you can hold it against your allowance and against other bids without guessing what was excluded.
03
Permits and plan review
Commercial work goes through formal plan review, which takes time. We build that window into the schedule up front rather than discovering it.
04
Build
One project manager coordinating every trade, reporting on a set cadence. You hear about problems from us, early.
05
Inspection and turnover
Final inspections, certificate of occupancy, punch list closed, and a team that answers the phone after you open.

Frequently Asked Questions

What is a tenant improvement?

A tenant improvement, or TI, is the work that turns a leased shell or an existing space into the space your business actually needs: framing, mechanical, electrical, plumbing, finishes, and casework. It is distinct from ground-up construction, which starts at sitework and foundations and runs on a much longer timeline.

How long does a commercial build-out take in Wichita?

Construction is often the shorter half. Commercial plan review through the building department takes real time, and long-lead items like mechanical equipment and casework drive the rest. We give you a schedule that shows both, so your opening date is based on the whole process rather than just the construction weeks.

Who pays for the build-out, me or the landlord?

It depends entirely on your lease. Most commercial leases include a tenant improvement allowance, and what that allowance covers varies widely. Bring us the lease when we walk the space; knowing what the landlord is delivering changes the scope and sometimes changes what is worth negotiating.

Can you work while we stay open?

Yes, and for occupied renovations that is usually the requirement rather than the exception. We phase the work, seal off active areas, and schedule the disruptive parts around your operating hours. It costs some efficiency and we will be straight with you about that tradeoff.

Do you handle the permits and inspections?

Yes, including submitting to the correct jurisdiction, which in this metro is not always the county office. Wichita, Derby, Bel Aire, and Park City all run different desks. We handle submittals, corrections, and inspection scheduling as part of the contract.

Can you do the millwork and casework too?

Yes, and it is one of the main reasons to hire us for a build-out. Reception desks, transaction counters, breakroom cabinetry, and built-ins come out of our own Wichita shop, which removes one of the longest lead times in the job and keeps the quality under our control.
