Construction at Lawton-Fort Sill Regional Airport

Work next to an active runway starts with a rule that does not bend: nothing on the job may interfere with an aircraft. We build terminal, hangar, apron and landside projects for owners at Lawton-Fort Sill Regional Airport with that rule at the front of the safety plan, the schedule and every subcontract. The airport sits in south Lawton, and its project list is shaped by federal grants, airline and military use, and a small staff that has to run an airfield while a contractor builds on it.

The airfield is more capable than many visitors assume. The Oklahoma Aerospace Commission lists Runway 17/35 at 8,599 feet by 150 feet of concrete with an instrument landing system, a primary role in the national airport system, a control tower, and fuel in both 100LL and Jet A1+. Its based aircraft include 42 single-engine airplanes, 4 multi-engine airplanes, 4 jets and 3 helicopters. That mix covers general aviation, charter and heavier operations, and each type brings different needs for hangar width, door height and apron strength.

Terminal, apron and taxiway projects

The airport's recent projects show how the work is funded and phased. In September 2021 a $1.1 million FAA Airport Improvement grant started the next terminal phases, including a third boarding gate, a renovated security checkpoint and a first official baggage claim, in a terminal project the director estimated at about $9 million. In September 2024 the City Council accepted a $270,000 FAA grant, on a project total of $300,000, for a preliminary engineering report on relocating Taxiway F, which does not meet FAA standards, and on expanding or repairing the terminal apron for military and other large aircraft.

Notice the sequence. A grant pays for a report, the report defines the design, and the design is bid later. A builder who gets involved at the report stage can help the airport test constructability, staging and cost before the numbers are fixed. We are glad to review preliminary scopes with an airport sponsor. For landside buildings and aprons, our page on truck courts and dock aprons shows how we think about heavy concrete pavement, and design-build delivery suits tenant hangars well.

Airside safety, access and construction phasing

A construction safety and phasing plan is a requirement of federally funded airport work, and it is the document that decides how the job actually runs. It identifies the work area, the haul routes, the hours, the barricades and lighting, the equipment height limits, the contact with the control tower, and who can enter the movement area and under what escort. We write our part of it so the superintendent, the foremen and every driver can read it in a few minutes.

Foreign object debris is the daily hazard. A stray bolt or a chunk of gravel on a taxiway can damage an engine, so we sweep, inspect and keep construction material away from the movement area. Cranes and tall equipment need approval because they can penetrate protected airspace. Vehicles in the work area carry the required marking and lighting. Airport security rules apply to workers as well, so we plan badging time with the airport office the same way we would plan it at the Fort Sill gate.

Hangars, terminal space and airside support buildings

The most common privately funded project at a general aviation airport is a hangar. Our page on the aircraft hangar covers clear spans, door systems and fire protection in detail. The short version is that a hangar is a large clear-span metal or steel building with a heavy, flat concrete floor, an oversized door, foam or sprinkler fire suppression sized to the aircraft inside, and a pavement apron in front that matches what the airport will allow.

Terminal and support buildings are a different task. They are small, finish-intensive and security-sensitive, and they bring airline, concession and screening requirements to a site with limited lay-down space. Owners comparing structural systems for a larger shell can read about clear-span rigid frame buildings.

The industrial park next door

The Lawton-Fort Sill Economic Development Corporation describes its Airport Industrial Park, in south Lawton at Highway 277 and I-44, as certified site ready, with a 43-acre site and a 71-acre site plus parcels of 40, 25 and 75 acres owned by the Commissioners of the Land Office. The park's secure access to airport facilities is aimed at aerospace users. Our page on the Airport Industrial Park covers building on those parcels.

An aerospace tenant often wants a building that combines production or maintenance space with ramp access. That combination puts a hangar-like door, a heavy slab and apron paving in one project, with airport approval layered over city permits. Our page on manufacturing facility construction describes the process side, and we coordinate the two.

Owners who hold land near the field should think about what a future tenant will ask for. Commercial real estate developers can build a shell with a heavy slab, generous clear height and utilities stubbed to the property line, and let the tenant add the airside door and apron once the use is known. That keeps the first-phase cost down and keeps the building marketable to more than one kind of user. We help price that shell, including the pavement and drainage that a later apron will need, so the second phase does not tear up the first.

Grant calendars and construction seasons

Grant-funded airport work runs on federal calendars. Funds are awarded, bids are advertised, contracts are signed and the work must be finished within the grant's period. Paving needs warm and dry weather, so the practical window for runway, taxiway and apron concrete is the late spring through early fall. We plan procurement so that joint material, dowels, reinforcing and mix designs are approved before the paving crew mobilizes.

Closures are the other constraint. A runway or taxiway closure must be coordinated with the airlines, the tower and the military users, and it is announced in advance. We build a schedule around the approved closure window and hold the crews, the equipment and the material ready. Anything we can build off the movement area, such as precast, joint sealing prep and utility work, is done outside the closure so the closed hours are used for paving alone.

Common Questions

Can a hangar be built while the airport stays open?

Yes. The work area is separated from the movement area, haul routes avoid taxiways, and the airport approves the plan. Cranes and tall equipment require review for height.

What does an FAA grant mean for a contractor?

Federally funded work follows federal bidding, wage and documentation rules, and the airport sponsor administers the contract. We prepare submittals and pay records to the standard those rules require.

What size aircraft does the runway support?

The runway is listed at 8,599 feet by 150 feet of concrete with an instrument landing system. For aircraft-specific questions about weight or approach, we refer owners to the airport and its engineer.

How do you handle security and badging?

Airport security rules set who may enter and how. We submit names early, assign escorts when required and keep a log of every person and vehicle entering the work area.

Is the taxiway project designed?

A 2024 grant funded a preliminary engineering report on relocating a taxiway that does not meet FAA standards and on the terminal apron. A design and bid would follow that report, so the scope is not final.
