Construction Services

What We Do

ESI provides industry-leading electrical construction services across Ohio and the surrounding region. Our expertise in design-assist and preconstruction helps us exceed our customers’ expectations by safely completing projects on time and within budget. We have deep experience in a variety of markets, including commercial, government, health care, education and sustainable construction.

Our industrial division performs commercial and industrial electrical construction for a variety of customers, including automotive manufacturers and energy generation facilities.

Electric Vehicle Charging Stations

ESI provides electric vehicle charging station installation services. Our capabilities include all underground conduit, wiring, switchgear and hardware installation.

Our team includes several EVITP-certified electricians. Contact us today for more information on installing EV chargers at your business or facility.


Long before work begins at a project site, ESI’s team is planning and preparing for a safe, efficient and quality outcome. Our preconstruction team collaborates with owners, general contractors and other trades to identify and resolve challenges. Working through challenges during preconstruction allows us to execute our work as efficiently as possible.

Our estimators collaborate with numerous stakeholders, making real-time changes and analyzing a variety of cost impacts, such as feeder routing and adjusted fixture and device counts. We use current market prices during the estimating process, increasing the accuracy of our estimates.

ESI’s prefabrication shop, The Innovation Center, offers hundreds of electrical assembly and kitting options.

BIM and 3D Coordination

We optimize project design and construction through building information modeling and 3D coordination. We provide quantity, take off, estimating, scheduling, coordination, clash detection and visualization. This process ensures all materials fit as designed. Our BIM experts use REVIT for design coordination and model fabrication.

We fabricate a growing percentage of project components at our Innovation Center. Prefabricating components in a controlled environment increases safety, improves efficiency and reduces costs.


As a design-assist contractor, we value open communication and collaboration among all team members. We lean on our team’s deep experience as well as their formal, ongoing training to achieve effective constructability reviews. Our project managers and field supervisors are involved in every phase of a project, ensuring successful delivery from design through construction.

ESI’s design-assist services include:

  • Reviewing proposed systems designs and impacts to costs, schedule and constructability.
  • Determining front-end specifications, including measures for temporary facilities and 3D coordination.
  • Field investigation support for coordinating design and verifying routing of systems, materials and construction methods.
  • Identifying ways to simplify installation methods while lowering labor and project costs without compromising quality.

Community Partners

Across Ohio and the nation, the construction industry has one common goal: to grow and develop the communities in which we live and work. We are proud to partner with several construction companies that hold Minority & Women Business Certificates. Our long-standing relationships with these MWBE contractors have proven to be mutually beneficial as we learn from each other while delivering quality projects to our customers.
