David, The Professional

David attended Georgia’s Institute of Technology, where he graduated with a Bachelor’s degree in Mechanical Engineering in 1992. He moved to Florida, where he worked with a few engineering firms until being given the opportunity to start BCH Mechanical’s engineering company, Engineering Concepts. The first project for Engineering Concepts was a 60,000 SF addition to Transitions Optical, including 10,000 SF of Class 100 Cleanrooms. After developing an understanding of cleanroom design, he was able to identify common cleanroom design/construction issues and remediate several other cleanrooms that had design issues.

After running Engineering Concepts for several years, he started Advanced Systems Engineering, Inc. in January of 2000.

David has quickly gained a reputation in the marketplace for being the Go-To Engineer for Pharmaceutical and Cleanroom Design. He has current working relationships with Cleanroom Clients including Honeywell, Bausch & Lomb, BD Biosciences, Florida State University, Wells Pharmacy, VistaPharm, West Pharmaceuticals, CoreRx, Xcelience, GE, PGT, Transitions Optical, PixelTeq, Medtronics, Formulated Solutions, and many others. Some of his Design-Build Cleanroom clients include Siemens, Energy Service Group, Southern Equipment, Total Building Solutions, Mecon, BCH Mechanical, Murray Company, Bay Area Building Solutions, Southern Plaza, and Construction Services, Inc.

David is licensed in Florida, Alabama, Arkansas, California, Georgia, Idaho, Illinois, Louisiana, Minnesota, Nevada, New Hampshire, North Carolina, Oklahoma, Pennsylvania, South Carolina, Utah and Virginia, and West Virginia. He is a member of ASHRAE, ISPE, Bio Florida, and ASPE.

David, The Man
David is a resident of Safety Harbor, Florida, where he lives with his wife of 20+ years, Susan, and their two children, Brandon and Brittany. He is a faithful member of Calvary Baptist Church in Clearwater, Florida, where he serves and worships regularly. David is an avid spearfisherman who looks for every opportunity to bring home some fresh fish from the Gulf of Mexico. His most recent hobby is racing his Nissan GTR Nismo at Sebring International Raceway and in Autocross, where he competes alongside family and several ASE employees. He has other modified cars on the track, including his Porsche 718 Boxster S, Infiniti G35, Mustang GT, Scion FRS, and Subaru BRZ.

David loves anything “adventure” – other hobbies include dirt biking, action pistol shooting, and sporting clays. He also enjoys scuba diving, lobstering, zip-lining, white water rafting, and anything that will give him a little adrenaline rush!

Jeff Hauser

Facilities Manager, Anazao Health

“The entire Team from ASE was very professional and highly qualified to work through all of our design challenges and special requests, which I had many! The group was fully engaged, working crazy hours to meet all of our MEP requirements and key dates. We now have a great plan for our future lab and entire facility, and our goal is to start renovation in 2021.”

Todd R. Daviau

President & CEO, CoreRx, Inc.

“We have now collaborated with David’s group to create solutions for two projects (both oral solids/non-sterile). David’s team worked with us the entire way and provided insight and asked questions others had forgotten, or did not ask. David’s team was able to specify several options of dehumidification equipment and provided recommendations for HVAC modifications if needed. This will also lead to future business as our capabilities have improved.

And very importantly, the overall cost of the project was relatively low. Thanks again! We will certainly work with David’s group in the future.”

Ted Koontz

Vice President, Operations, Xcelience, LLC

We recently collaborated with David’s group to create a low-humidity cleanroom in a pharmaceutical environment (oral solids/non-sterile). David’s team worked with us the entire way. They specified several options of dehumidification equipment and provided recommendations for HVAC modifications if needed.

Overall, the project cost was kept low and the work was very efficient. The original goal was to achieve relative humidity at 35%. In the end, we are able to provide very tight control of humidity down to levels as low as 30%. This has enabled us to achieve a big goal, which in turn greatly helps our customers.

This will also lead to future business as our capabilities have improved. And, very importantly, the overall cost of the project was very low. Thanks again! We will definitely work with David’s group in the future.

Doron Deutsch

Engineering Facilities Manager, BD Biosciences

When I was first promoted in 2000 to the position of Engineering and Facility Manager in a large Pharmaceutical company, I had to resolve the persistent humidity problem in our large ISO 7 and ISO 5 cleanrooms. After several unsuccessful attempts by professional HVAC firms to correct the problem, I contacted David Bess. He determined that the drain lines of our large air handlers were installed incorrectly and proposed a simple and inexpensive way to correct the problem. I was skeptical since no other engineer that looked at the system mentioned the drain lines as a possible root cause. However, it was an easy and inexpensive fix so I gave it a try and it worked very well.

Since then, I hired David to design several HVAC and low humidity systems for cleanroom applications. All the systems that he designed for me worked very well. I would gladly recommend David for designing any cleanroom and low humidity HVAC system.

Ernesto Barnat

Facilities Manager, CONMED Corporation

David was hired in 2012 to provide design services for an ISO Class 7 Cleanroom at our medical device manufacturing facility. The space climate requirements included 25% RH and 68F. David’s design proved to be a robust solution for our needs, achieving better than expected space conditions.

I would recommend David for providing HVAC engineering services; especially for low temp/humidity design requirements.

Kevin Smith

Facilities Manager, Exactech

David is a detail-oriented Engineer who is capable of designing critical process HVAC systems that work flawlessly from concept to implementation. Design criteria for one of the projects he worked with me on was 40 +/- 2%RH and 70 +/- 2 degrees F. Based on the aforementioned results as well as other projects, I would and subsequently have recommended David and his firm for critical process design work up to and including clean rooms.

Mark Licarde

Vice President & COO, CoreRx, Inc.

“David is an expert in his profession with extensive experience in the design of pharmaceutical manufacturing spaces. He is an innovative individual that sets high expectations for himself and displays a willingness to do whatever it takes to get the job successfully completed.

His knowledge and expertise have proven to be a great asset to CoreRx. He and his staff were instrumental in the successful design of our cleanroom environment, and we as a company are grateful for their contribution and their dedication to our success.”
