DTR Consulting Services has moved our Los Angeles Area Office to better serve our A/E Clients in the Southern California area. The new location provides for future growth and easier access to area freeways.

Overseeing this office is the Firm’s Managing Principal, Thomas Berger, RCI, CSI, CDT, SCIP.   In addition to running the new Phoenix Area Office, he is overseeing the expansion of this office.  DTR Consulting Services continues to work with Architectural and Engineering Clients in the Los Angeles, Orange County and San Diego Area since early 2006.  This move allows DTR to build on our current client base and to expand our Firm to better serve our current and future A/E Clients.

Tom will be evaluating and recruiting the best new staff, the area has available.  He will be in charge coaching new staff members into the existing DTR Culture and provide training for both experienced and junior members in the DTR approach to serving our Architectural Clients. DTR will be looking to hire both Building Envelope Engineers, Specifiers and Quality Control Staff.

What have we Learned

Incorporating Lessons Learned

Albert Einstein

Education is what remains after one has forgotten what one has learned in school.

This term means different things to different people. I was fortunate early in my career to work for some really great organizations. It was there that I first saw the implementation of "Lessons Learned" through tracking reports and Lunch & Learn meetings in which those of us that were in the field, shared problems we faced that were either attributed too, or not helped by our own construction documents.

When founding DTR Consulting Services I felt this feedback was extremely important, especially for Consultants who may not get the same field exposure as the architectural person in the field would on a weekly basis. How many times do you answer questions in the field or respond to an RFI because something on the documents is not clear or conflicts with another portion of the documents. Many of us have seen this time and time again.

As a technical consultant, we rely on our Clients to give us feedback on our specifications or other technical services. It is through that feedback along with individual experience with current field conditions that we develop our services.

It is also with that same experience we like to conduct client presentations/ discussions in which we can interject specific case studies into a common theme topic to get direct feedback from CA folks, Project Architects & Project Manager.

In many of these presentations we identify items that caused additional work on the part of the Architect or Engineer (or both) which ultimately hurts your firm in lost revenue. Some of these items result in Change Orders, others simply consume time. Both are counterproductive.


Test & Measure


How do we know what we are doing is working?

We Measure... Our Change Order Goal Rate is less than one half of one percent. We are currently well below that. Ask us to track this on your project.
