Testimonials

“Rush Copley Medical Center has utilized Erika L. Bolger, P.E and John Thomas, P.E. to provide design and consulting  services for a variety of complex projects.  Those  projects involved patient care areas, critical power distributions systems and highly technical diagnostic suites.  As such Erika and John have become valued members of our project teams.  Their knowledge of complex mechanical and electrical systems combined with their depth of experience was always evident.   However, their ability to effectively partner with our vendors, contractors and hospital staff contributed to well coordinate projects, with excellent outcomes.  Rush Copley Medical Center will continue to rely on Erika and John whenever we have a project that demands thoughtful coordination and attention to details.”

​“Erika and her team have always delivered an outstanding set of drawings and always found solutions to the most complex engineering problems.  Most recently, we worked together on two Starbucks and a Goose Island bar at O’Hare airport.  Airports are one of the most challenging areas to build within and O’Hare may be one of the toughest.  Erika and her team’s ability to understand the obstacles, design accordingly and ultimately deliver real world solutions is invaluable to an organization like HMSHost."

​"Engineers John Thomas, Erika Bolger and [their] team greatly support our architectural work with solid mechanical, electrical and plumbing Permit, Bid and Construction Documents.  When working with clients, John is quick to provide timely and accurate solutions that resolve important code and logistical problems that are created with the many conditions that we have on our new and existing building projects.  I have been working with John for about 17 years."

"Erika is one of those dedicated professionals that I have come to rely on.  Erika and her team consistently provide efficient and concise engineering solutions.  Working with Erika and her team on a recent ground up municipal project I was consistently impressed with the level of expertise, depth of knowledge and thorough coordination of their work.  It made the architectural and engineering coordination efficient and resulted in a well-coordinated, tight set of drawings.  Erika’s professional attitude and positive attitude make her a pleasure to work with."

"I've personally worked with John Thomas on several complex healthcare projects where Hill Mechanical Corp. was awarded the contracts for HVAC and medical gas work. John works with the construction team in a "team-minded" approach in an effort to deliver the highest quality product and level of satisfaction to the Owner and ensuring the intent of design is achieved. I believe John is a true professional in his field. We look forward to working with John and BTR Engineering on future projects."

John routinely impresses me with his ability to combine his 27+ years of experience with new ideas and technology to solve problems. This combination brings creative, innovative and cost effective solutions to his clients. John’s attention to his client’s needs is evident in all of our interactions. I am sure these qualities are major contributors to John’s continued success."
