CONSTRUCTION

Ackerman-Estvold was selected by the North Dakota Department of Transportation to complete the construction engineering for this selective hot mix asphalt (HMA) mill and overlay and bridge deck overlay on US 83 from 20Ave SW in Minot to the south urban limits. The selective HMA mill and overlay targets locations most in need of repair, which are areas of excessive pavement rutting. Patching was completed along this 1.25 mile stretch of roadway along with ADA improvements to the existing sidewalk and curb ramps on 31Ave SW. The bridge deck overlay included a 1.5 inch concrete overlay of the existing 250’ by 90’ bridge on US Hwy 83 over US Hwy 2/52. Additional repairs to the bridge included full depth concrete deck repair, w-beam guardrail retrofit, replacement of the approach slabs, and approach slab lip repair.

Ackerman-Estvold’s construction team was responsible for overall project management and coordination of the construction of this project. Responsibilities included site inspection, daily project documentation, construction layout, processing change orders and pay estimates through NDDOT’s CARS program, and final records. Responsibilities unique to the bridge deck overlay included sounding of the deck to determine limits of repair, field modifications to the traffic control to account for the different phases of work and the multiple on and off ramps at the bridge ends, and setting profile of the bridge for the overlay. The project was completed in 2016 at a construction cost of $1.6 million.
