“I have had the opportunity to work closely with PBS Engineers, Inc. for over 10 years with our projects in Ontario, El Segundo and San Diego. PBS Engineers has provided mechanical, electrical and plumbing design services for our projects. Inclusive of design services, are estimated construction cost estimates and project/construction administration support. In our long term relationship, PBS has always been flexible, sensitive to our designs and effective responses to Request to Information requests – either during the bid process or construction phase. PBS Engineers is a very respective firm established around professional and dedicated individuals.”

“I am writing this Letter of Recommendation of behalf of PBS Engineers regarding their professional electrical engineering design services.  HOK has worked continuously with PBS Engineers for eight years on over 20 projects, specifically aviation related, at LAX, Ontario and Van Nuys.  On each project PBS has demonstrated a collaborative spirit and delivered the design in a timely manner.  Delivery of construction documents and specifications has always been on time and contractors have benefited from the well thought out designs, which kept them on schedule with issues in the field.”

Vice President Aviation + Transportation


“Morrow-Meadows is pleased to have the opportunity of providing a reference for PBS Engineers.  In recent years we worked with the PBS Team on a number of design-build projects for which they provided electrical power distribution and lighting design services.  Overall, their performance had a major impact on project success.  All tasks were executed in a timely manner, within the budgeted cost and without unexpected change issues.  We’d recommend PBS Engineers as a valuable asset to your upcoming endeavors.”
