DP-NXA works closely with the owners representative to understand how their sites operate to ensure that minimal to no impact occurs to their operations during design and construction phase of a project.  Working at a University or hospital can be quite challenging and we understand the importance of working with the owners to identify the best methods for carrying out our task.  We make sure that we adhere strictly to all security and safety mandates for the owner’s sites.  Our team of professionals take the time to walk down all the project locations to ensure that we understand the existing conditions as well as the constraints that might be encountered by a construction contractor. We develop designs with an understanding of what it takes to maintain and operate the facility.  We consult with the owners and general contractors to make sure that the design solution we develop meets owner’s expectations and can be constructed with the minimum of impact to the their ongoing operations.
