Change Order 2 and 3 for Well House 16, City Project 416.docx EXECUTIVE SUMMARY City Council Meeting: November 5, 2018 AGENDA ITEM: Change Order 2 and 3 for Well House 16, City Project 416 AGENDA SECTION: Consent PREPARED BY: Brian Erickson, PE, Director of Public Works/City Engineer AGENDA NO. 6.j. ATTACHMENTS: Water Main Extension Proposal; Gate Valve Replacement Proposal APPROVED BY: LJM RECOMMENDED ACTION: Motion to approve a Change Orders 2 and 3 for additional work required to complete the work required on Well House 16, City Project 416 BACKGROUND On October 3, 2017, City Council awarded the construction contract for Well House #16 to Rice Lake Construction Group (RLCG). On May 1, 2018, Council approved Change Order 1 to the contract. At this time RLCG has nearly completed their work on this project and there are two remaining changes that have been negotiated for this project. Change Order 2 covers three additional elements of work not covered under the contract. While performing excavation as part of their work, RLCG discovered a large concrete block that required removal in order to install the necessary underground piping. That work required significantly more effort than standard excavation resulting in added cost. Also, as part of the utility system Well 16 is required to be connected to the SCADA network. Unfortunately, the planned fiber routing needed to be adjusted which required a change to the length as well as the need to add tracer wire to the route to insure it can be located in the future. Total cost for Change Order 2 is $27,724.00. Change Order 3 cover the following additional work items. Additional electrical work was required to locate the transformer as required by Dakota Electric resulting in additional wiring and conduit that was not shown in the original design. Due to the difficulty of maintaining a turf area near the retaining wall, staff requested that the area be filled with concrete resulting in additional cost. Finally, contractor testing of the well pump and associated components resulted in significant power usage which was charged to the city by Dakota Electric. As a result, the city is receiving a deductive change to cover this cost. Total cost for Change Order 3 is $10,830.35. RECOMMENDATION Staff recommends Council approval of the attached change orders in order to complete the construction of Well House 16, City Project 416.
