PROBLEM/ISSUE STATEMENT
The City Council will consider awarding a Professional Engineering Services Contract to Sanderson Stewart, in the amount of $558,975.00 for design, bidding and construction administration services on Schedule 3 of the 2017 Water and Sewer Main Replacement Projects. The Schedule 3 project consists of approximately 2,000 lineal feet of 20-inch water main replacement and 2,100 lineal feet of 18-inch sanitary sewer main replacement in 6th Avenue North from N. 27th Street to Grand Avenue.
Sanderson Stewart was selected based on City staff review of project proposals submitted by prequalified firms. Other firms considered for the work were Morrison-Maierle, Inc., DOWL, and Great West Engineering.
The City replaces and upgrades its sanitary sewer and water utilities as part of an annual maintenance program. As underground water and sewer utilities approach the end of their useful life, the City's maintenance costs and potential liabilities from system failures increase. Deteriorating sanitary sewer mains crack, misalign and are intruded by tree roots. These problems lead to leakage of wastewater into surrounding soils, groundwater inflow, loss in carrying capacity and sewage backups into public and private property. Corroding water main and leaking joints cause water loss and reduced service capacity. Water main breaks often cause public and private property damage.

ALTERNATIVES ANALYZED
City Council may:
- Approve awarding the Professional Engineering Services Contract to Sanderson Stewart, or;
- Do not approve awarding the Professional Engineering Services Contract to Sanderson Stewart. If the project is not constructed, the City's sanitary sewer collection and water distribution systems in this area will continue to experience ongoing maintenance problems and expenses.
