Bid 7837— Increase in Change Order Authority • Page 2 DISCUSSION: During the installation of the sewer pipeline along Martin Luther King Boulevard, G. Hurtado encountered unknown and unmarked underground utility pipes. The unmarked utilities have required the contractor to halt construction to pothole the depth and alignment of the unmarked pipes, staff has had to redesign the sewer line alignment, and staff has directed the contractor to utilize jack and bore construction method which is significantly more expensive than open trench construction to avoid impacts to the conflicting utilities. STRATEGIC PLAN ALIGNMENT: This item contributes to Strategic Priority 6 - Infrastructure, Mobility, and Connectivity and Goal 6.2 — Maintain, protect, and improve assets and infrastructure within the City's built environment to ensure and enhance reliability, resiliency, sustainability, and facilitate connectivity. This project aligns with each of the five Cross -Cutting Threads as follows: 1. Community Trust — This Project is in the community's best interest by ensuring reliable sewer services for the University Drive residents. 2. Equity — This Project will provide equitable distribution of sewer services to all residents in the University Drive. 3. Fiscal Responsibility — This Project will provide a net saving in maintenance and operation cost since it is cheaper to maintain sewer pipes than a sewer pump station. 4. Innovation — This Project exemplifies "out of the box" thinking by identify an alternative to provide gravity sewer services to an area that was previously served by a pump station. 5. Sustainability & Resiliency — This Project promotes growth by installing gravity sewer pipes to serve a neighborhood.
