Title
Resolution Approving a Construction Contract with 53 Corporation, LLC, for the Covy Court Stormwater Improvements Project [1795-1819 Covy Court]
Body
________________________________________________________________________________
Executive Summary
Castle Rock Water is seeking Town Council approval of a Resolution (Attachment A) awarding a Construction Contract (Exhibit 1) to 53 Corporation, LLC, for the Covy Court Stormwater Improvements Project. The contract amount is $698,530.00, plus staff requests a 10% Town-managed contingency in the amount of $69,853.00, for a total project authorization of $768,383.00. This project will be funded through the Stormwater Fund, and is located within Woodlands Master Association owned open space north and east of Covy Court (see Attachment B). This project will replace an existing surface drainage swale system with underground storm sewer pipe and manholes to eliminate frequent overtopping of the swales that has resulted in damage to the open space and concrete trail traversing the area. The project is scheduled to be completed by November 2022.
Notification and Outreach Efforts
All of the proposed improvements will be constructed within HOA owned open space, over which the Town has a drainage easement in place for construction and maintenance of storm drainage facilities. Property owners in the vicinity of the project, along with Woodlands Master Association will be notified in advance of the start of construction and informed of the project’s scope and duration. Periodic construction updates will be provided for the project’s duration. Temporary traffic modifications (trucks and equipment entering/exiting the project site) and construction noise during normal working hours will occur during the project’s duration
History of Past Town Council, Boards & Commissions, or Other Discussions
This item was presented to the Castle Rock Water Commission on June 22, 2022, and the Commission voted unanimously 6 - 0 to recommend approval to Town Council.
Discussion
This project is intended to improve an existing surface drainage ditch system for two separate storm sewer outfalls in the open space north and west of Covy Court. This system has insufficient capacity to convey major storm flows and presents both an undue maintenance burden to the Town and danger to pedestrians using the concrete trail that traverses this area. Storm overflows result in erosion of the slopes and damage to native vegetation, along with shortening the service life of the concrete trail. Additionally, frequent ice buildup on the trail in the winter is a safety hazard to users.
The Town solicited construction bids via Rocky Mountain BidNet. Bids were received from three (3) contractors and are shown below:
