Title
Resolution Approving an Agreement between the Town of Castle Rock and WL Contractors, Inc. for Traffic Signal Installation (Founders Parkway/Copper Cloud Drive, Founders Parkway/Black Pine Drive and Ridge Road / King Soopers Intersections)
Body
________________________________________________________________________________
Executive Summary
Each year the Transportation Planning and Traffic Engineering Division evaluates the need for a traffic signal at intersections through a warrant analysis. Two intersections located in the southeast portion of Castle Rock are planned to begin construction of a new traffic signal in the spring of 2016. They are:
• Founders Parkway (Hwy 86) at Black Pine Drive / Copper Cloud Drive
• Ridge Road at King Soopers
The purpose of this memo is to request approval for the selected contractor, and allocation of funds to complete the signalization of the listed intersections. WL Contractors provided the lowest construction bid at $372,407. Funding for the purchase of the equipment and for the completion of the installations is included within the Division’s Capital Improvement budget (Account 120-3175-431.75-26).
Our plan is to complete construction of both of these signals by September, 2016. With the signal pole order already in place the remainder of the equipment and supplies will be furnished by the contractor awarded to construct the signals.
Notification and Outreach Efforts
Staff has worked with Community Relations in order to provide public outreach to citizens on status updates for the project with regard to the completion of the Founders Parkway and Black Pine Drive / Copper Cloud, and Ridge Road at King Soopers intersections. Public outreach occurred in the form of updates at HOA meetings and postcard mailers. The postcard mailer went out to the residents in the area in March 2016.
History of Past Town Council, Boards & Commissions, or Other Discussions
There will be a presentation at the May 2nd, 2016 Public Works Commission to obtain the Commission’s recommendation to Town Council for the installation of a traffic signal at Founders Parkway (Hwy 86) and Black Pine Drive / Copper Cloud Drive, and Founders Parkway (Hwy 86) and Ridge Road. The Commission’s recommendation will be provided to Town Council as part of the presentation materials.
Discussion
The Town’s goal for the Traffic Signal Capital Improvement Program is to identify locations that a traffic signal will improve operation efficiency and safety. Staff performs engineering evaluations at various intersections on an annual basis in order to make sure these goals are being achieved. Through the help of the Federal Highway Administration’s (FHWA) Manual on Uniform Traffic Control Devices (MUTCD) staff uses this to help aide in determining if a signal is an appropriate means of traffic control at a given location.
Attachment B shows the location of the two intersections set to be signalized as part of the 2016 construction projects. The completed engineering evaluations suggest that a signal be recommended at both of these intersections. The total delay and overall efficiency will be improved for vehicles accessing Founders Parkway and Ridge Road.
The following shows the engineer’s estimate and contractor bid results for clarity and illustration purposes.
Remaining 2016 Budget (less signal pole purchase): $397,005
WL Contractors: $372,407
Sturgeon Electric: $383,838
Two bids were received for this project. The low bid was checked for accuracy, along with references, and documents reviewed for contract compliance. It is believed that all contractors that submitted a bid are fully competent to complete the work. Based on this, staff recommends WL Contractors based on their bid, and quality of work on past projects for the Town. Construction will be complete by the end of summer.
Budget Impact
The 2016 Traffic Signal Capital Improvement budget contains $480,000 for traffic signal installations. A total of $121,000 of this total budget will be funded from developer contributions from the Castle Oaks development. In order to help reduce costs and speed up the installation schedule signal poles and mast arms were ordered in advance, as well as the traffic signal cabinets. The remaining amount in the budget for this project is $397,005. The total encumbrance amount requested in the attached Resolution (Attachment A) is $387,407. This includes a contingency amount of $15,000. The full recommended encumbrance is under the available budget.
Staff Recommendation
Staff recommends approval of the attached resolution to contract with WL Contractors Incorporated for the completion of the 2016 traffic signal construction projects.
Proposed Motion
“I move to approve a Resolution approving an Agreement between the Town of Castle Rock and WL Contractors, Inc. for Traffic Signal Installation (Founders Parkway/Copper Cloud Drive, Founders Parkway/Black Pine Drive and Ridge Road/King Soopers Intersections)”
