BEYOND CORE EPC
Additional Specialized Services
PLC Construction’s capabilities extend well beyond the three EPC pillars. Through our in-house fabrication shop, to advanced automation engineering and comprehensive pressure relief studies, we deliver a wide range of specialized services – delivering the full breadth of support Houston’s industrial operators need through a single, trusted firm.
Fabrication Shop Services
PLC Construction operates a Houston-area fabrication shop equipped to support structural steel, pipe spool, skid, and module fabrication for capital projects across the Gulf Coast. Our in-house fabrication capabilities eliminate the interface risk and procurement lead times associated with third-party fabricators, allowing us to maintain direct control over quality, schedule, and cost. The shop supports both standalone fabrication contracts and fully integrated EPC project delivery.
Control Panel Fabrication
PLC Construction provides in-house design and fabrication of custom industrial control panels, MCC lineups, and electrical enclosures. All panels are engineered to project-specific loop diagrams and instrument schedules and fully factory-tested prior to site delivery. This approach reduces field installation time and minimizes commissioning risk for projects throughout the Houston area and the Gulf Coast.
Construction Project Management
PLC Construction provides standalone construction project management services for clients seeking an experienced construction management (CM) team without full EPC delivery. Our project managers are deeply embedded in Houston’s industrial market, overseeing multi-contractor scopes, owner interfaces, schedule, project controls, and safety programs across the petrochemical and midstream sectors.
Design-Build Services
Industrial Automation & Control Systems Engineering
SCADA Systems
PLC Construction provides the design, programming, integration, and commissioning of PLC-based control systems and SCADA platforms for industrial facilities across the Greater Houston area. Our integrators have experience across major platforms—including Allen‑Bradley, Siemens, ABB, and Emerson—and develop SCADA solutions tailored to operator requirements, ranging from single-unit control applications to multi-site supervisory systems.
Commissioning Services
Systematic pre-commissioning, commissioning, and startup services that get Houston-area industrial facilities to safe, reliable operations. Our commissioning team develops and executes mechanical completion check-sheets, loop checks, functional tests, and performance testing protocols, working closely with owner operations teams to ensure smooth handover and fully documented startup readiness.
Pressure Relief & Flare System Studies
Process safety engineering studies for Pressure Safety Valves (PSVs) & pressure relief valve (PRV) sizing, relief system design, and flare system capacity analysis — critical compliance deliverables for Houston’s refining and petrochemical facilities operating under API 520/521 and OSHA PSM requirements. Studies support both greenfield design and relief system validation for existing units undergoing modification or regulatory review.
Field Service Engineering
On-site technical support from PLC Construction’s experienced field engineers for installation oversight, technical issue resolution, and construction quality verification. Field service personnel are deployed to Gulf Coast facilities to support turnarounds, capital projects, and maintenance programs — providing the engineering judgment in the field that prevents costly rework and keeps projects moving.
LOCAL MARKET EXPERTISE
Embedded in Houston's
Industrial Construction Market for Over Two Decades
The Greater Houston area represents one of the world’s most concentrated clusters of petrochemical, refining, and midstream infrastructure. The Ship Channel corridor alone accounts for a significant share of U.S. refining and chemical processing capacity.
Working in this environment requires more than general EPC capability. Our project managers have pull permits in Harris, Galveston, and Brazoria counties. Our supervisors know turnaround schedules at facilities from Baytown to Freeport. Our procurement team maintains active relationships with Houston-area distributors, fabricators, and specialty suppliers.
PLC Construction is not a national contractor with a Houston satellite office — we are a Houston Construction & Engineering Firm with national capability.

FAQ
Common Questions About EPC
Contracting in Houston
What does an EPC company do? What industries does PLC Construction serve in Houston?
An EPC company — short for Engineering, Procurement, and Construction — provides a single-contract delivery model for industrial capital projects. Instead of managing three separate contractors, owners work with one firm responsible for designing the facility, sourcing all equipment and materials, and completing construction. This reduces interface risk, simplifies contracting, and gives owners a single point of accountability from project kickoff through commissioning.
What industries does PLC Construction serve in Houston?
PLC Construction serves the oil & gas, renewables/municipal, and water treatment sectors across the Greater Houston area. Our project history spans petrochemical plant expansions, refinery capital projects and turnarounds, natural gas compressor stations, renewable energy facilities, and municipal water/wastewater treatment plant — working with major integrated operators and independent owner-operators across Harris, Galveston, and Brazoria counties.
How is an EPC contract different from EPCM?
Under an EPC contract, the contractor holds full responsibility for engineering, procurement, and construction — including cost and schedule risk. Under an EPCM (Engineering, Procurement, and Construction Management) model, the contractor manages the work on behalf of the owner but does not hold subcontracts or carry the same level of risk. EPC is typically preferred for owners seeking maximum schedule certainty and a fixed lump-sum price.
What geographic area does PLC Construction cover?
From our Houston base, PLC Construction self-performs work across the Gulf Coast region, including the Ship Channel industrial corridor, Pasadena, Deer Park, Baytown, Texas City, Freeport, and into Southeast Texas markets including Beaumont and Port Arthur. For the right project, we also operate in the Lake Charles, Louisiana corridor and other Gulf Coast locations.
How do I select the right EPC company for my Houston project?
Evaluate EPC contractors on four dimensions: technical capability in your specific process sector, local market knowledge (permitting, craft labor, vendor relationships), demonstrated safety performance (TRIR, man-hours), and financial capacity to carry the project scope. Request references from recent projects of similar scale and complexity. Lowest price does not equal best value on capital projects; delays and rework introduce significant operational costs.
Does PLC Construction self-perform construction work?
PLC Construction is a self-perform contractor. Our core craft labor — pipefitters, ironworkers, electricians, and instrumentation technicians — are direct employees or long-term craft partners, not subcontractors layered beneath us. This gives us direct control over quality, safety, schedule and procurement standards. For specialty scopes, we maintain a vetted local subcontractor network that have similar if not the same core values as PLC.
What certifications and safety standards does PLC Construction maintain?
PLC Construction maintains an OSHA-compliant safety management system, NCCER-certified craft workforce, and ongoing participation in ISNetworld, Veriforce and Avetta — the contractor qualification platforms commonly required by major Gulf Coast operators. Our safety record reflects a culture built around daily toolbox talks, behavior-based safety observation programs, and zero-tolerance policies for at-risk behavior.
