Project/ Issue Relates To: ❑X Council Goals/Priorities ❑X Adopted Master Plan(s) ❑Not Applicable BACKGROUND The City's 2013 Wastewater Master Plan (WWMP) identifies the Lakewood Trunk Rehabilitation (T-LW-1) as one of several pipeline repair projects. The wastewater mainline was identified to have less than 10 years of remaining useful life. Staff was hopeful the issues could be addressed via pipe-lining in order to minimize costs and impact. However, once the design phase started, the pipe was found to have several significant sags, or low spots, which can lead to blockages and overflows. These sags can only be corrected through open excavation and replacement. This project will replace the Lakewood sewer trunk line restoring the useful life, reducing risk of overflows, and minimizing infiltration and inflow (I/I) into the City's sewer system. 503.635.0215 380 A Avenue PO BOX 369 Lake Oswego, OR 97034 www.lakeosweao.city Page 2 DISCUSSION City staff contracted with Wallis Engineering to perform professional engineering design of the identified improvements. The project limits are along State Street/Hwy 43 from North Shore Road to just north of Foothills Road. The scope of work developed includes about 850 linear feet of new sewer mainline, 7 new manholes, and the corresponding restoration (asphalt, pavement markings, landscaping, etc.) of the disturbed area. The project did end up costing more than originally anticipated in the WWMP, as the extreme depth (18 feet) was not realized during the master planning process, and other components were added to the scope for efficiency and viability. This project was advertised on February 23rd and 25th. Bids were opened on March 17th with one proposal received as listed in the table below. Construction is expected to begin in May 2022 and be completed a few months later. Contractor Icon Construction & Development Bid $ 740,864 Bid Points 90 COBID Points 0 Total Points 90 Rank 1 This bid was about 8% higher than the engineer's estimate of$684,599. While only one bid was received, staff believes it to be reasonable and responsible. Considering the current market volatility in labor and materials, depth of the sewer, and traffic control requirements on State Street, a bid of 8%over the engineer's estimate is reasonable. Alternatively, the bid could be rejected and the bid re-advertised, however there is no reason to believe the resulting bids would be lower. Staff recommends awarding the contract to Icon Construction & Development as the most cost-effective means to delivering this project. FISCAL NOTE This project is budgeted from the Wastewater fund. Anticipated project expenses by phase are shown in the table below. Project Phase Expected Cost Design $110,000 City Payroll $40,000 Construction $750,000 Total $900,000 The 21-23 Biennium CIP indicated $230,000 for this project. That estimate was taken from the 2013 Master Plan which underestimated several components of this project, and the scope was expanded to incorporate several other aspects in the area to ensure a "dig once" approach to addressing the wastewater facility as a whole. To account for the difference between the initial CIP budget and the current estimates, staff plans to submit a budget modification. Also, other 503.635.0215 380 A Avenue PO BOX 369 Lake Oswego, OR 97034 www.lakeoswego.city Page 3 wastewater projects identified for starting within the current biennium have been pushed out into the future. Therefore, sufficient wastewater funds will be available to address this project cost. RECOMMENDATION Authorize the City Manager to sign a public improvement contract with Icon Construction & Development, LLC for construction of the Work Order 311 - Lakewood Trunk (T-LW-1) project in the amount of$740,864. 503.635.0215 380 A Avenue PO BOX 369 Lake Oswego, OR 97034 www.lakeoswego.city
