Services

You need a partner with a long-term lens, and experience accounting for the unexpected.  We’re experts at solving complex problems and finding solutions that stem from rapid growth and/or outdated systems.

Problems we solve

Growth is inevitable. Ensuring infrastructure needs and critical systems like basic utilities and wastewater facilities are capable of handling increased capacity and designed in such a way that not only meets current demand, but accounts for projected future capacity is vital to efficient planning. Improper planning or poor execution can result in millions of dollars in damages, extended disruption to occupants, and significant environmental hazards.

Water Sewer Pipeline Construction

We deliver expert construction of water distribution and sanitary sewer systems for commercial, industrial, and municipal infrastructure. Our work includes open-cut installation of gravity sewers, force mains, and water transmission mains, utilizing materials such as ductile iron, PVC, HDPE, and concrete pipe. Projects are executed to meet engineered specifications and regulatory standards, with attention to hydraulic performance, structural reliability, and long-term operational efficiency.

Pump Station Rehab/
New Construction

We provide comprehensive rehabilitation and new construction services for clean and wastewater pump stations in municipal and industrial water systems. Our capabilities include structural modifications, pump replacements, and the installation of suction and discharge piping across all pump styles, including submersible, suction lift, split-case, and vertical turbine configurations. Each project features detailed construction sequencing and bypass pumping plans to ensure uninterrupted system operation. All work complies with AWWA and state regulatory standards, with a focus on hydraulic efficiency, long-term reliability, and minimal operational impact.

Water and Wastewater Plant Rehab/New Construction

We provide full-service rehabilitation and new construction for water and wastewater treatment facilities, supporting municipal and industrial clients. Our expertise spans structural improvements, process equipment installation, piping and valve systems, and integration of all major treatment components. We work across all process types—from conventional activated sludge and membrane systems to chemical treatment and filtration—delivering solutions tailored to plant capacity and compliance requirements. Each project includes comprehensive phasing, bypassing, and construction sequencing to maintain operational continuity while meeting all regulatory and performance standards.

Mechanical Equipment Install and Processes

We specialize in the installation of mechanical process equipment for water and wastewater treatment facilities, pump stations, and related infrastructure. Our experience includes a wide range of systems such as pumps, blowers, mixers, clarifiers, aeration systems, chemical feed equipment, and sludge handling components. Installations are executed with precision alignment, anchoring, and system integration to ensure optimal performance and longevity. All work is performed in coordination with process requirements, construction sequencing, and startup testing, in full compliance with design specifications and regulatory standards.

Industrial Construction

We provide industrial construction services for water, wastewater, utility, energy, and warehouse facility projects. Our capabilities include structural concrete, equipment setting, process piping, heavy civil construction, and warehouse upfits. Whether supporting infrastructure upgrades or interior buildouts, we prioritize safety, schedule control, and compliance with project specifications and regulatory standards. Projects are executed with detailed construction sequencing and coordination with ongoing operations to minimize disruption and ensure long-term facility performance.

I have been working with Gilbert Engineering in the Charlotte Metro area since 2021. Throughout our collaboration on various projects, I have been consistently impressed with their honesty, integrity, and their no-conflict approach. Their commitment to delivering high-quality work is truly commendable. Gilbert Engineering has proven to be a reliable partner, and I have no reservations in highly recommending them for any future projects.
