Title
Resolution Approving the Second Amendment to the Service Agreement between the Town of Castle Rock and Burns & McDonnell Engineering for the Front Street Downtown Connection, RWRWTC Pump Upgrades and Liggett Road Pipe Upsize Projects [Located in various locations throughout Castle Rock, CO]
Body
________________________________________________________________________________
Executive Summary
Castle Rock Water (CRW) staff seeks Town Council approval of a Resolution (Attachment A) approving the Second Amendment to the services agreement with Burns & McDonnell Engineering (BMcD) for the Front Street Downtown Connection, Ray Waterman Regional Water Treatment Center (RWRWTC) Pump Upgrades and Liggett Road Pipe Upsize Projects (Exhibit 1). This proposed Second Amendment is a contract addition in the amount of $149,178 and an extension of the contract through September 30, 2026. The new revised contract amount would be $576,899 which is outside the original Council Authorization of $446,050. This will allow extension of the engineering design services to get through bid phase services and allow for Construction of the Front Street Pipeline to begin in Fall of 2025.
Budget Impact
The proposed Second Amendment is in the amount of $149,178. This will exceed the $405,500 contract amount, plus $40,550 contingency originally approved by Council for the Front Street Downtown Connection, RWRWTC Pump Upgrades, and Liggett Road Pipe Upsize Projects. Amendment 1 increased BMcD’s Contracted amount by $22,221 and was covered by the original contingency amount. Staff recommend approving BMcD’s proposed Second Amendment in the amount of $149,178 which would bring the total contract amount to $576,899. Staff recommend retaining the remaining original contingency ($18,329) to help offset potential changes that may arise as the design of the trenchless bore under UPRR progresses. The following account information applies to all agreements related to design services for the Front Street Downtown Connection, RWRWTC Pump Upgrades, and Liggett Road Upsize projects.
