PROBLEM/ISSUE STATEMENT
The City Council is asked to consider awarding a professional engineering services contract to Morrison Maierle, Inc. (MMI) in the amount of $700,240.00 for design, bidding and construction administration services on Schedule 2 of the 2015 Water and Sanitary Sewer Main Replacement projects. The Schedule 2 projects consist of approximately 11,300 linear feet of sanitary sewer main replacement in two geographic areas. The smaller area is the alley between Avenue D and E from 17th to 21st Street West. The larger area is bounded by the BBWA Canal to the north, 6th Avenue North to the south, North 24th Street to the west, and North 12th Street to the east.
MMI was selected based on City staff review of project proposals submitted by prequalified firms. Other firms considered for the work were DOWL HKM and Sanderson Stewart.
The City replaces and upgrades its sanitary sewer utilities as part of an annual maintenance program. As underground 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.

ALTERNATIVES ANALYZED
City Council may:
- Approve award of the engineering contract to Morrison Maeirle, Inc.; or
- Do not approve award of the engineering contract to MMI. If the project is not constructed, the City’s sanitary sewer distribution system in this area will continue to experience ongoing maintenance problems and expenses.
FINANCIAL IMPACT
Funding for this project has been approved by City Council in the Capital Improvement Program (CIP). Funding is sufficient for the engineering design and construction administration portion of the project which is now under consideration, as well as for the project construction planned for bidding to contractors in April, 2015. Schedule 2 projects will use wastewater funds:
| Sanitary Sewer Replacements | |
| Project Budget | $4,000,000 |
| Previously Encumbered | $0 |
| This Contract | $700,240 |
| Budget Remaining | $3,299,760 |
RECOMMENDATION
Staff recommends that Council award a professional engineering services contract for the design and construction administration of Schedule 2 of the 2015 Water and Sanitary Sewer Main Replacement Projects to Morrison Maierle, Inc. in the amount not to exceed $700,240.00.
