On March 26, 2013, Armstrong Glen was contacted by the City of Charlotte Storm Water Services, regarding an urgent need for engineering assistance. The Brentwood Phase II Capital Improvement Project was in early bid phase. Drawings and calculations for six special storm water structures had been previously submitted to NCDOT for review and comment. A long list of serious comments came back from NCDOT, and Charlotte Storm Water was informed that the structural engineer who prepared the original calculations had gone out of business. Storm Water needed the drawings and structural calculations redone immediately by another engineer. Armstrong Glen agreed to tackle the task. Armstrong Glen dedicated one professional engineer and one engineering technician entirely to completion of the work. Charlotte Storm Water stated that the schedule had to be shortened due to the project already being in bid phase for thirty days. Armstrong Glen began work on the six special structures. Four of the structures were junction boxes, one was a catch basin, and one was a large and complicated headwall/retaining wall. Design calculations and drawings continued for thirteen straight days, including Saturday and Sunday and were submitted to NCDOT for review. The submitted package was approved by NCDOT, and an encroachment permit for the work was issued in early June of 2013.
