Authorize the Executive Director of Public Works to terminate for convenience the contract extended <br />to Paulus Engineering for construction of the Seventeenth Street Water Main, originally awarded in <br />the amount not to exceed of $1,832,571, but now closing the contract for a $1,287,167.64 total. <br />2.

Approve Change Order No. 3 which is a final closeout credit, reducing the contract by $818,547. <br />DISCUSSION <br />On December 2, 2014, the City awarded a construction contract to Paulus Engineering, Inc., to replace the <br />water main in Seventeenth Street from Bristol to Broadway for a total not to exceed amount of $1,832,571. <br />The water main being replaced was installed in the 1930's and had begun to experience a number of <br />breaks and leaks. Based on critical factors such as age, history of breaks, size, location, and system <br />redundancy, this water main was the highest priority for replacement. <br />During the first phase of construction between Broadway and Flower (Exhibit 1), the contractor <br />encountered a number of utilities that were not identified in the contract documents. The interfering <br />utilities made it necessary either to realign the water main or to relocate the interfering utilities. Either <br />option resulted in major project delays and additional costs, some of which would be the City's <br />responsibility. <br />Generally, record information, such as that provided in the contract documents, is sufficiently accurate to <br />account for minor realignment and adjustments. However, the variation encountered for this project was <br />too great to proceed without potholing, which is an accurate and cost - effective method of establishing <br />utility alignments. In preparation for the second phase of construction between Flower and Bristol, staff <br />directed the contractor to pothole the existing utilities to verify underground alignments and soil conditions. <br />After reviewing the pothole information, staff confirmed that the water main would require numerous <br />realignments and adjustments resulting in substantial additional costs. Therefore, staff recommends the <br />23A -1 <br />
