On each of our EPC projects, ESI serves as the general contractor, subcontracting as much as possible with local contractors in the project area. ESI's design group prepares multiple, specific bid packages for each phase of construction. Since each design and engineering project is never the same, the specific bid package is totally customized per the exact specifications of the project. In this management scenario we can truly act as the customer's representative on the construction site, demanding high quality from our subcontractors. This construction execution methodology truly eliminates conflicts of interest generally associated with design/build.

We see construction management as a vital part of a total EPC solution. We purchase all of the specialty equipment, perform the design engineering, and place on-site experienced professionals who can manage the construction of a steam and power facility. We then recruit and utilize the very best skilled and productive crafts people in a given project area. ESI's project execution approach is focused toward tapping an existing productive, strong local talent resource.

While on-site, the field staff is responsible for all construction trade subcontractors and the implementation of ESI's construction quality control and safety procedures, assuring construction compliance with ESI and vendor design drawings and specifications.

After award of contracts for trade subcontractors, the field construction staff is responsible for the day-to-day management, supervision, and administration of all trade subcontractors. Specifically, ESI's field construction staff is responsible for the following during the construction phase:


  • Review and award of trade subcontracts.
  • Receipt and verification of all materials and equipment.

  • Orderly storage of materials and equipment on-site.
  • Implementation and monitoring of ESI's Jobsite Safety Program.

  • Communication and interfacing with client's staff as required.

  • Liaison and communication with ESI's home office staff regarding overall project status.

  • Monitoring and review of subcontractor performance to assure compliance with drawings and specifications.

  • Implementation and monitoring of ESI's Jobsite Quality Control Program to assure that the work being performed is to the highest level of quality consistent with design requirements.

  • Field accounting, including approval of subcontractor invoices for payment (by the home office).

  • Issuing of field purchase orders for miscellaneous materials and supplies.

  • Preparation of weekly work schedule reports, including schedule updates and analysis of subcontractor performance.

  • Coordination and interfacing between all trade subcontractors.

  • Providing direct construction supervision to all trade subcontractor superintendents.

  • Implementation and monitoring of the site security program consistent with ESI and the client's requirements.

  • Supervision and coordination of system checkout, testing, and start-up activities.

  • Coordination of vendor service and start-up personnel regarding the initial checkout and start-up of vendor- supplied equipment.

  • Supervision of the overall plant start-up and operator training program.

  • Demonstration of performance of the system.

  • Implementation of ESI’s Drug Testing Program applied to all ESI and subcontractor personnel.

Our on site field staff is augmented as required to maintain high quality installations by frequent visits from our project manager and engineering department members. These visits close the loop on the project by ensuring that the installation is being performed based on the intent of the design as well as providing valuable feedback on design features so improvements can be made on future projects.
