Mesquite and Sandhill Boulevards are the main arterial streets that run through the center of the city of Mesquite. These roads are typically very busy. Being located in the downtown district, there is a cross road at nearly every block.
The water system in the downtown district is a grid that follows the street layout. This project replaced existing small diameter water lines in Mesquite and Sandhill Blvd., that were no longer adequate, with a large diameter 16-inch line. The plans detailed complicated tie-in connections to existing water lines at each intersection, and detailed service connections for businesses and residences alike.
The project involved asphalt removal and replacement, trenching, working around other utilities, traffic control, providing access, working with the City of Mesquite, businesses, residents, NDOT and permitting.
At that time, Mesquite Blvd. was an NDOT Right-of-Way; an NDOT encroachment permit was required and obtained. In that the roadways had existed for many years, the contractor had many unexpected underground conflicts that due diligence planning and design work had missed due to lack of records. The existing water lines were removed or abandoned as necessary.
