DBA crews are finishing up construction of two roundabouts in San Tan Valley for Pinal County. DBA is offering competitive pay and excellent benefits for an experienced Heavy Civil Construction Estimator. Working under our Job Order Contract with the City of Scottsdale, DBA recently completed construction of the improved intersection of Dynamite and Pima Roads. Continuous development in the area created heavy traffic and back-ups in the left-turn cue. This was causing added congestion in the intersection and increased the potential for crashes.
