NEW L.A. Office

DTR Los Angeles Office


DTR Consulting Services, the "Building Science Guys", have opened a new Los Angeles Area Office, just north of the downtown area, to better serve our Clients in the L.A. metropolitan area. This office is in addition to the current Orange County office in Irvine and two other northern California offices. This new office location allows for the continued expansion of DTR and also serves as a central location to service our clients in a more efficient manner.

Overseeing this new office is the Office Leader | Senior Building Envelope Architect, Kirk O'Brien, AIA, RCI, NCARB. Kirk brings with him a long history of experience and connection to the local community. DTR Consulting Services continues to work with Building Owners, Developers and Architectural/Engineering Clients in the Los Angeles, Orange County and San Diego Area since early 2003. This move allows DTR to build upon our current client base and to expand our Firm to better serve our current and future A/E Clients.

DTR will also be recruiting the best new technical staff, the area has available. He will be in charge mentoring new staff members into the existing DTR Culture and provide guidance for both experienced and junior members in the DTR approach to serving our Architectural Clients. DTR will be looking to hire both Building Envelope Consultants specialized in Building Science, Technical Architects, Specifiers and Field Quality Control Staff.

Design Services

DTR Consulting Services provides the services of an Architectural Hardware Consultant (AHC). Whether we write your project specifications or your firm produces your own, having a well coordinated, non-proprietary hardware specification, hardware sets, openings list and a well coordinated door/frame schedule on your drawings is directly related to the amount of time your firm will spend on the construction submittals and potential cost related changes in the field due to incomplete or incorrect hardware sets and incompatibility of hardware doors and frames specified.

 The additional benefit of our service is door hardware which is consistent with your design, selection of products that do not impair sightlines and that are appropriate for the usage of the facility and specific opening. An unknown benefit is that many times proprietary hardware is specified without your knowledge driving costs up on items that impact other areas of the project.
