Title
Resolution Approving the Third Amendment to the Services Agreement Between the Town of Castle Rock and Burns & McDonnell Engineering Company, Inc. for the Front Street Downtown Connection, RWRWTC Pump Upgrades, & Liggett Road Pipe Upsize Projects [Ray Waterman Regional Water Treatment Center; 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 Third 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 Third Amendment is a contract addition in the amount of $126,613 and an extension of the contract through March 31, 2027. The new revised contract amount would be $703,512 which is outside the current Council Authorization of $595,228. The primary purpose of the Third Amendment is to retain BMcD for construction phase services on the Front Street Downtown Connection project, as well as include some additional design services to accommodate a revised alignment for the Liggett Road pipeline after negotiations with property owners in the original alignment were unsuccessful.
Budget Impact
The proposed Third Amendment is in the amount of $126,613. This will exceed the remaining contingency available in the current $595,228 total authorization amount. Staff recommends approving BMcD’s proposed Third Amendment in the amount of $126,613 which would bring the total contract amount to $703,512. The remaining contingency of $18,329 will be retained. The costs associated with this amendment will be broken down as follows: $107,659.50 towards the Front Street Downtown Connection Project (Project No. 250011) and $18,953.50 towards the Liggett Road Pipe Upsize Project (Project NO. 250012).
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.
