Since 1973, PEC has been providing geotechnical engineering services for projects including buildings, local streets, state and interstate highways, airports, bridges, transmission lines, utilities, and other types of infrastructure. We recognize the benefits of digging deeper into the data we obtain from our subsurface explorations to provide you high quality, less costly construction solutions.

Empowered by our own nationally accredited materials testing laboratory, rotary drill rigs, truck-mounted Mobile B-31 and track-mounted Mobile B-57, we are flexible and can go through all terrains.

With the ability to drill 250′ below the surface, PEC’s geotechnical team applies established technologies and testing procedures to investigate, analyze, and develop geotechnical engineering recommendations and design. PEC drilling crews have performed subsurface explorations, rock coring, and monitor well installation or abandonment throughout the region.

Services We Offer:

• Foundation soil evaluation
• Monitor well installation and abandonment
• Pavement design
• Remedial foundation design and construction recommendations
• Rock coring
• Settlement analysis
• Shallow and deep foundation design
• Site preparation and earthwork construction
• Slope stability analysis
• Subsurface explorations

Intentional and quality inspection services throughout the course of a project is vital to its success. PEC knows the importance of quality control and what is essential for a successful project. Our inspection services will ensure project compliance with contract documents and applicable regulations and codes during construction. Our inspectors will verify materials prior to being installed, monitor contract progress versus construction schedule, keep accurate and clear project records, and will services as a critical communication link.

We interact with the Owner, Architect, Engineer, Contractor, and project stakeholders by sending construction progress updates, upcoming project needs, project non-compliance, and any other pertinent information. Our integrity and work ethic drives us to work hard for you every day. By providing open and timely communications, thorough inspections, and accurate project documentation during construction, PEC gives you confidence that your project will be built and delivered successfully.

Materials used to create your project can literally determine success or failure. Knowing what comprises those materials is vital when making decisions for design and construction. You need to be confident in the foundations, structures, and terrains with which you are working. Our expertise can bring peace of mind through every step of the project.

PEC has provided quality construction materials testing and special inspections for over 40 years. Our team of engineers and technicians are highly trained to provide quality services to our clients, and we know what is important to assure quality control. Attention to detail, careful processes, and accurate reporting are all top priorities for our teams.

Successful projects begin with accurate information. Surveying is not about the process, it’s about the flawless interpretation of information. That’s where our expertise and training benefits you the most. Whether surveying for private companies, federal agencies or local public authorities, PEC surveyors’ precise instrumentation and experienced crews supply the digital data necessary for seamless design. PEC crews are equipped with the latest technology in automated data collection and measurement systems, including 3D laser scanning for immediate transfer.

Our staff uses global positioning satellite (GPS) receivers to coordinate calculations and employs the latest robotic survey equipment. Where appropriate, rapid data collection methods such as airborne LiDAR or photogrammetry/aerial mapping is completed using drones. All our drone pilots are FAA Part 107 certified to meet the requirements for commercial UAS operations. No matter the project, our survey team will use experience and capabilities to provide you an efficient and accurate solution.
