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.
