Andrews, Hammock & Powell, Inc. is a multi-disciplined consulting firm consisting of mechanical and electrical engineers, commissioning agents, construction administrators, and support personnel working together to serve the interests and needs of our clients. For every assignment, we endeavor to achieve design excellence, and at Andrews, Hammock & Powell, Inc., we believe the key to productive design stems from the Principals’ personal involvement in the design of every project.  Accordingly, we have structured our firm’s size and areas of practice to achieve that goal.  We have developed an excellent working relationship with our clients over the years.  As a result, our practice has grown through repeat work and referrals from past clients. The dedicated efforts of our skilled engineers, designers, CAD operators, and support personnel allow us to provide our clients with a single source of responsibility for all their mechanical, electrical, and plumbing design needs. We are confident we have the staff and experience necessary to provide the solutions you need.


In December, 1988, after challenging careers as project engineers and engineering managers, Al Andrews, Chuck Hammock and Ed Powell began the mechanical/electrical consulting engineering firm of Andrews, Hammock, & Powell, Inc.  Subsequently, Wesley Haynes and Naeem Osmani joined the firm as partners. Jake Andrews started at AH&P in 2003 and was promoted to principal in 2020. All of the principals are engineers first and managers second. They are active in the design of every project designed by AH&P, so each client receives senior participation in each and every project regardless of size or complexity.

In 2001, due to the growth of the firm, AH&P moved from our original location on Ingleside Ave to our current location on Charter Lane.  AH&P also recognized the need to upgrade our services during the construction phase of our projects. We developed a full time construction administration department. Jim Hughes, P.E., heads this department. He and his staff visit our projects as needed or required each month to ensure the construction materials and workmanship comply with the Contract Documents. Jim also expedites submittal reviews; answers RFI’s; and expedites change order review and approval to keep the construction progressing.

In 2003, AH&P recognized the need to provide Commissioning, Equipment Start-up, and TAB services. This need grew out of the fact that many times, the contractor did not leave the project with the equipment, systems, and controls working as specified. To accomplish this work we now have several certified NEBB commissioning and TAB agents on staff. We have the knowledge, instruments and tools required to commission the mechanical and electrical equipment to insure the systems meet the Owner’s Project Requirements (OPRs) and are installed and operating as specified. We have provided this service for clients as far west as Missouri, as far north as Illinois and as far east as Delaware.
