SECTOR EXPERIENCE
TEXAS INDUSTRIES WE SERVE
UPSTREAM OIL & GAS
Production facility construction and expansion across the Permian Basin and Eagle Ford — wellhead tie-ins, separation trains, produced water handling, compression stations, and saltwater disposal facilities. Full EPC delivery for both greenfield and brownfield upstream assets, with direct field presence in Midland/Odessa and Kermit operating areas.
PLC’s founding, self-performed I&E capability is particularly valued on upstream projects, where instrumentation and electrical scope often drives the critical path.
MIDSTREAM
Gathering system construction, gas processing facilities, NGL fractionation, metering and custody transfer stations, and compressor stations. PLC has delivered complete EPC scopes for cryogenic gas processing plants — an area requiring integrated engineering with material specifications for low-temperature service, modular construction sequencing, and SCADA integration that generalist contractors routinely underestimate.
Cryogenic service demands EPC delivery: when design, procurement, and installation sit with different firms, material and interface mismatches surface only at startup — after weeks of cold-down and commissioning. PLC eliminates that exposure.
PETROCHEMICAL & REFINING
Process unit construction and revamps at Gulf Coast petrochemical complexes and refineries — instrumentation and control system upgrades, piping modifications, structural steel, and full EPC delivery of new process units. Direct experience with TCEQ permitting, OSHA PSM requirements, and the hot-work and turnaround protocols of operating facilities along the Houston Ship Channel.
INDUSTRIAL & POWER
Power generation facility construction, industrial plant I&E and mechanical projects, and custom automation integration for manufacturing and process industries. PLC’s control systems engineering team assesses, designs, engineers, and procures both PLC-based and DCS-based control systems for any facility type — delivering automation scope that most EPC firms subcontract out.
PIPELINE INFRASTRUCTURE
Pipeline construction and integrity projects across Texas — from new transmission line construction through inspection, ILI dig verifications, hydrotesting, and cathodic protection surveys. In-house pipeline engineers handle routing studies, Texas Railroad Commission regulatory filings, environmental compliance documentation, and construction management across Texas and adjacent states.

QUESTIONS & ANSWERS
WHAT IS AN EPC COMPANY AND WHAT DOES AN EPC CONTRACTOR DO?
An EPC company — Engineering, Procurement, and Construction — is a contractor that assumes single-point responsibility for delivering a complete, operational facility under one contract. The EPC contractor manages all engineering and design work, procures all materials and equipment (typically representing 40–60% of total project cost), and executes all construction activities. The project owner receives a turnkey, commissioned facility ready for operation.
WHAT IS THE DIFFERENCE BETWEEN AN EPC CONTRACT AND AN EPCH CONTRACT?
Under an EPC contract, the contractor takes on responsibility for delivering the completed facility and absorbs cost and schedule risk — delivering a turnkey solution at a fixed price. Under an EPCM (Engineering, Procurement, and Construction Management) contract, the contractor manages the process but the owner retains direct contracts with vendors and subcontractors — transferring more risk back to the owner in exchange for greater control. EPC is typically preferred when the owner wants fixed-price certainty and single-source accountability; EPCM suits owners with significant in-house project management capability who prefer direct vendor relationships.
HOW DO I SELECT AN EPC CONTRACTOR FOR AN OIL AND GAS PROJECT IN TEXAS?
Key evaluation criteria include: (1) self-perform capability across all required disciplines to avoid subcontractor coordination risk; (2) demonstrated experience in the specific project type and Texas operating environment; (3) in-house engineering staff with registered Professional Engineers and automation/SCADA depth; (4) safety record including TRIR, EMR, and compliance with operator prequalification platforms such as ISNetworld, Veriforce, or Avetta; and (5) financial stability and bonding capacity appropriate to the contract value.
WHAT INDUSTRIES DO EPC COMPANIES SERVE IN TEXAS?
Texas EPC contractors primarily serve upstream oil and gas (production facilities, compression, saltwater disposal), midstream (gathering systems, gas processing, NGL fractionation, pipeline), petrochemical and refining (Gulf Coast process units, I&E projects, turnarounds), and industrial/power generation sectors. PLC Construction operates across all of these sectors from its Texas base, with particular depth in Permian Basin upstream and midstream, Gulf Coast petrochemical, and statewide automation and control systems projects.
CAN PLC CONSTRUCTION HANDLE CRYOGENIC GAS PROCESSING PROJECTS?
Yes, PLC can provide complete EPC delivery for cryogenic gas processing facilities — including FEED, detailed engineering with material specifications for low-temperature service, vendor procurement and shop inspection of cold boxes and cryogenic equipment, modularized skid construction, and startup commissioning. Cryogenic service requires integrated EPC delivery. When design, procurement, and installation sit with different contractors, material and interface mismatches consistently surface at startup — after the project has already consumed cold-down time and schedule float. PLC’s integrated approach eliminates that exposure by design.
DOES PLC CONSTRUCTION OPERATE THROUGHOUT TEXAS OR ONLY SPECIFIC REGIONS?
PLC Construction is headquartered in Liberty, Texas, with a dedicated field office in Kermit, TX for Permian Basin operations. The firm operates throughout Texas and holds installation licenses in eight Midwestern and Southern U.S. states. Project teams have delivered work across Texas, including the Permian Basin, Eagle Ford Shale, Gulf Coast, Houston Ship Channel, and East Texas, to name a few. For projects outside Texas, PLC also provides engineering and construction management services internationally.
WHAT IS THE DIFFERENCE BETWEEN EPC AND DESIGN-BUILD FOR INDUSTRIAL PROJECTS?
EPC provides single-point responsibility with a fixed-price, lump-sum contract structure — the EPC contractor absorbs cost and schedule risks and delivers a turnkey operational facility. Design-Build combines design and construction under one contract but typically involves more owner participation, shared risk, and variable pricing. For large-scale projects in oil and gas, EPC is the preferred model because it aligns contractor incentive with the owner’s core objective: a completed, operational facility at a predictable cost. Design-Build is more common in commercial construction where scope is less technically complex and owner involvement in design is higher.
