Construction Engineering

Innovative Engineering & Design Solutions – From Concept to Construction

PLC Engineering Services delivers comprehensive, multi-disciplinary EPC solutions.

Our team of licensed civil, process, mechanical, electrical, and instrumentation engineers brings deep expertise across every stage of a project—from early conceptual studies through detailed design and field engineering support during construction.

We serve both greenfield and brownfield projects, delivering reliable, cost-effective designs for production facilities, site expansions, and natural gas facilities. With experience in multi-well pad developments, our scopes include civil, structural, mechanical, process, electrical, and instrumentation engineering—ensuring fully integrated solutions that support safe, efficient, and sustainable operations.

Integrated In-House Engineering Services

Civil Engineering Services

Site development design, including grading, drainage, and utility layouts, in compliance with local and state regulations.
Preparation and coordination of construction documents for permitting and regulatory approvals.
Stormwater management design, including detention and retention systems and hydraulic calculations.
Utility infrastructure design, including water, sanitary sewer, and storm sewer systems.
Due diligence studies, feasibility analyses, and agency coordination to support site development projects.

PLC delivers integrated civil and structural engineering solutions backed by multi‑state licensure and extensive expertise in foundation systems, structural analysis, and land development. Our team provides comprehensive site development services, including site planning, grading and drainage design, and utility coordination, ensuring projects move efficiently from concept through permitting and construction.

We specialize in the design of reinforced concrete foundations for buildings and heavy industrial equipment, as well as engineered pipe supports, structural steel platforms, and access systems. Our foundation solutions include helical piles, drilled piers, and other deep foundation systems, developed in coordination with geotechnical data to ensure performance, constructability, and long‑term reliability.

We design containment structures and heavy‑duty foundation systems tailored to demanding operational environments. Our team performs detailed soil–structure interaction analyses to determine the most efficient and cost‑effective foundation approach for each project.

Through advanced structural modeling and stress analysis using RISA‑3D, we deliver precise structural steel designs and fabrication details. Our fully integrated 3D site models provide clients with clear visualization of foundations and structural systems, improving coordination, minimizing field conflicts, and enhancing overall project execution.

Structural Engineering Services

Design and analysis of reinforced concrete foundations for equipment and heavy industrial structures.
Structural design of steel platforms, access structures, and maintenance walkways for industrial facilities.
Pipe rack and pipe support structural design considering thermal loads, wind, and seismic forces.
Foundation systems for rotating and static equipment, including anchor bolt design and vibration considerations.
Structural assessments and retrofit design for existing industrial structures and foundations, in refineries or plants.

PLC’s Process & Mechanical Engineering team delivers high-value solutions backed by decades of experience in designing and building some of the nation’s largest facilities.

Our team has served a wide range of industries, including upstream and midstream oil and gas, agricultural processing, refining, chemical production, water treatment, and heavy industrial plants. From concept through startup, we provide full lifecycle support—feasibility studies, cost estimating, detailed design, and commissioning—to ensure your project is efficient, reliable, and built for the future.

Our Process & Mechanical Engineering teams work closely with PLC’s construction division to ensure designs align seamlessly with practical field implementation.

Our recent Projects

Featured Case Study

Condensate Stabilization Upgrade

Gas Plant Upgrade

PLC’s Engineering Services division deployed a multidisciplinary team comprised of process/mechanical, structural, electrical, instrumentation, and control systems engineering and design professionals to complete the list of deliverables for this project.

We provide our clients with solutions. We use the latest technologies in our detailed multidisciplinary designs. Our drawing package included foundations, structural steel, pipe routing and connections, and electrical power and control systems.

In parallel, PLC developed work plans and HAZID reviews, supporting proper shut-down planning activities. As detailed engineering nears completion, PLC supports our client in its construction efforts by providing IFC packages and scope of work descriptions for each major construction trade (i.e. foundations, mechanical, electrical & controls).

Project alignment and collaboration are key in any project PLC oversees; weekly communication with our clients is a priority, as well as scheduled design reviews. (i.e. 30%, 60%, 90% design reviews). An added benefit is our laser scan technology; PLC can lead a virtual version of the plant working areas during such reviews.

Vendor Document Reviews were also included in our execution strategy for this project. PLC successfully coordinated the review of all vendor documentation, soliciting our client’s input, and returned all comments to various vendors in a timely manner.

We are happy to discuss our past experiences further and take a deep dive into the details.
