Commercial General Contractor
Langston Construction Company is a commercial general contractor and industrial construction firm delivering heavy civil construction since 1969. We hold the prime contract, build with our own crews, and coordinate every trade to one schedule and one standard.
What general contracting means at Langston Construction Company
General contracting is one of four delivery methods Langston Construction Company offers, alongside construction management, design-build, and EPC. Every one of them starts with our preconstruction service. Under general contracting, the owner and the design team finish the drawings first. Langston Construction Company then bids or negotiates a single contract for the completed design, holds that contract as the prime, and delivers the finished project.
The difference from the other methods is where the risk and the design responsibility sit. Under design-build, we carry the design. Under construction management at-risk, we join before the design is complete and hold a guaranteed maximum price. Under EPC, we deliver engineering, procurement, and construction as one package. Under general contracting, the design is the owner's, the price is fixed to that design, and our job is to build it exactly as the engineer of record drew it, on the schedule we committed to.
What Langston Construction Company executes as your general contractor
As a commercial general contractor, we build the highest-risk civil and structural scope with our own crews and manage the trades. Industrial construction, heavy civil construction, and site work delivered to engineer-of-record drawings.
Prime contract and trade management
We hold the prime contract and manage every subcontractor and trade to one schedule, one budget, and one standard. Mechanical, electrical, plumbing, roofing, and specialty trades are procured, scheduled, and inspected by our project team, so the owner has one point of accountability.
Heavy civil and site work
Mass earthwork, grading, drainage, and site development to AASHTO and SCDOT, built by our own crews as the backbone of the project. The three-acre Anderson County Recycling Center site in Powdersville, SC (earthwork, paving, and washdown utilities under SCDHEC) is the kind of scope we self-perform.
Concrete and foundations
Cast-in-place foundations, equipment pads, and structural concrete to ACI 318. On the 92,000 SF Station Support Complex in Seneca, SC, that meant a five-story pre-stressed concrete structure on soil nails and micropiles.
Structural steel and pre-engineered buildings
Structural steel erection and connection welding to AISC 360 and AWS D1.1, plus pre-engineered metal buildings from foundation through envelope, such as the 57,000 SF T&S Brass warehouse in Travelers Rest, SC and the 58,437 SF Stevens Aerospace maintenance facility in Smyrna, TN.
Physical security
Perimeter fencing, walls, gates, and NERC CIP-014 hardening for critical-infrastructure and utility sites, delivered under the same prime contract as the civil work. See physical security construction.
Schedule and cost control
Field-driven scheduling and cost control from our preconstruction team, so the project stays on time and on budget. Because our own crews build the critical path, we control the float instead of negotiating for it.
Self-performed scope inside a general contract
Most general contractors broker the entire job. Langston Construction Company self-performs a substantial portion of every project: site civil, structural concrete, structural steel, and physical security. Engineering and the electrical scope are always delivered by qualified partners. Self-performing the civil and structural work does three things for an owner under a general contract.
Schedule certainty
The trades that set the critical path (earthwork, foundations, and steel) are our crews, so the schedule is a commitment we control rather than a promise we relay.
Quality control
The scope with the highest cost of rework is built to our standard and inspected by our superintendents before the trades build on top of it.
Safety
Our crews work under one safety program, backed by the 2026 AGC Construction Safety Excellence Award, 1st Place in the Utility Division. See safety at Langston Construction Company.
General contracting across the five core industries
One construction discipline, delivered across the five core industries Langston Construction Company serves. Heavy civil construction runs under all five.
Critical infrastructure
Site civil, foundations, and protection systems for energy and power owners, including grid protection and energy storage sites.
Physical security
Perimeter systems, access control, and ballistic walls for utilities and secured facilities, the company's primary differentiator.
Environmental
Water and wastewater treatment plants, pump stations, and municipal systems.
Industrial
Manufacturing, distribution, and data-center facilities, such as the 240,000 SF Southwark Metal manufacturing and distribution facility in Piedmont, SC and the 63,000 SF industrial renovation in Duncan, SC, delivered while the plant stayed in operation.
Commercial
Fire stations, training centers, office buildings, and retail facilities, such as the 9,235 SF four-bay Hobbysville Fire Station in Enoree, SC, the 14,000 SF Oconee Technical Training Center addition in Seneca, SC, and the 15,000 SF GBS Fletcher retail showroom renovation in Fletcher, NC.
How a general contract runs at Langston Construction Company
1. Bid or negotiated proposal
We price the completed drawings, qualify every assumption in writing, and flag constructability issues before award.
2. Buyout
Subcontracts and long-lead materials are bought against the estimate with named alternates, so scope gaps surface before mobilization.
3. Mobilization and self-performed civil
Our crews open the site, build the foundations and structure, and hand a finished substrate to the trades.
4. Trade coordination
One superintendent, one schedule, weekly look-ahead planning, and owner reporting against milestones.
5. Close-out
Punch list, commissioning support, as-builts, and warranty handover.
Why owners hire Langston Construction Company as general contractor
One construction discipline, delivered four ways. Owners hire Langston Construction Company as their commercial general contractor because our own crews have built a continuous industrial and heavy civil project record since 1969, backed by the 2026 AGC CSEA 1st Place award in the Utility Division.

Frequently asked questions
What does a general contractor do?
A general contractor holds the prime construction contract, builds the core scope, and manages every subcontractor and trade to deliver the project on one schedule and one budget.
How is general contracting different from design-build?
Under general contracting, the owner's design team completes the drawings first and Langston Construction Company builds to them under a fixed contract. Under design-build, Langston Construction Company carries the design and the construction under one contract from concept forward.
When should an owner choose general contracting over construction management at-risk?
General contracting fits a project whose design is complete and whose scope is stable, where a competitive fixed price is the priority. Construction management at-risk fits a project that needs the builder in the room during design, with a guaranteed maximum price set before the drawings are finished.
Does Langston Construction Company build with its own crews?
Yes. Langston Construction Company builds the highest-risk civil, concrete, and structural scope with our own crews, and manages the specialty trades around it. Engineering and the electrical scope are delivered by qualified partners.
What is heavy civil construction?
Heavy civil construction is the large-scale site, earthwork, concrete, and infrastructure work that forms the foundation of industrial and utility projects. It is the work Langston Construction Company builds in-house.
What industries does Langston Construction Company general contract in?
Five core industries: critical infrastructure (grid protection, energy storage, utility sites), physical security (perimeter systems, access control, ballistic walls), environmental (water and wastewater treatment), industrial (manufacturing, distribution, data centers), and commercial (fire stations, training centers, office buildings). Heavy civil construction runs under all five.
Does Langston Construction Company take bid work?
Yes. Langston Construction Company bids completed drawings for public and private owners and also negotiates general contracts directly. Owners and design teams can start through the request for bid page.
Where does Langston Construction Company work?
From our Southeast base, on utility, industrial, commercial, and infrastructure projects since 1969.
