Sustainable Design/LEED

Our LEED accredited professionals work closely with the architect to insure that appropriate strategies are implemented in our design in order to get points that will achieve the LEED Certification level goals established for the project.


In some cases the traditional design/bid/build project delivery method does not fit a client schedule or other requirements. In these cases we have a track record dating back almost 30 years for delivering projects through several versions of the popular design/build delivery method. In most cases we have actively worked as part of the contractor’s team to complete the project.

Construction Administration

PEA provides a unique ability to monitor and control both quality and cost during project construction. Services may include shop drawing/submittal review, RFI review/ response, attend periodic construction jobsite meetings, and provide periodic inspections including substantial completion and final inspections.


PEA can assist with the planning, documenting, scheduling, testing, adjusting, verifying, and training, to ensure that Mechanical, Plumbing, and Electrical systems function in accordance with the contract documents and per the Owner’s Project Requirements. The goal of the Commissioning Process is to enhance the quality of the delivered project by focusing the design and construction team on the Owner’s goals for a functional and energy efficient building. The earlier a Commissioning Provider is involved in the project process the greater the chance there is for the Commissioning Provider to influence corrections without increased costs later.

Feasibility Studies

We believe clients need the most accurate assessments in order to make the decisions to implement project solutions that best serve their interests. Feasibility studies require the knowledge to analyze solutions at significantly higher levels of uncertainty because they are done early in the conceptual stage. We provide the required field study, conceptual layouts, and evaluations necessary to determine whether capital costs are compatible with project goals.

System Condition Assessments

PEA provides evaluation and report of mechanical and electrical systems and equipment. The assessment involves equipment measurements, overall performance, condition and age. Often, estimates are made regarding the remaining life of equipment. Data is prepared to determine costs associated with upgrade or replacement. A final plan of priorities is established.

Value Engineering

Most projects are restricted by budget. As such, PEA’s team is experienced in working with owners, architects, and contractors to aid in developing alternate design solutions that help control/reduce first costs while maintaining the owner’s project objectives.
