Story

Driesenga & Associates, Inc. (D&A) has provided complete design and construction engineering services on several road reconstruction projects. This work generally entailed completed removal and replacement of the existing road surface, reconstruction of existing sanitary sewer, water main, and storm sewer, installation of new sidewalk, curb and gutter, HMA surfacing and slope restoration. In addition to the complete design and construction engineering, D&A has assisted the City with topographic surveying, construction staking, materials testing, inspection, and construction contract administration. Sample projects are: 17th Street, 15th Street, 14th Street, 5th Street, 40th Street, Fairbanks Avenue, 8th Street, and Country Club Road. Work on these projects included the topographic survey, design, plan preparation, construction documents, opinion of probable cost, construction engineering and project management, construction staking, field inspection, and as-built drawings. Design and construction challenges include maintaining the existing sewer and water services during replacement of the utilities and avoiding conflicts with existing utilities in the older portions of the City neighborhoods. Due to the residential nature, it was usually required that the project be constructed while maintaining at least one usable lane at all times. Contract administration was completed with the use of MDOT FieldManager software.
