Resolution Approving a Construction Contract with Velocity Constructors, Inc. for the Well CR-231 Well Facility Project




Executive Summary


Castle Rock Water is seeking Town Council approval of a resolution approving a construction contract (Attachment A) with Velocity Constructors, Inc. (Velocity) for the Well CR-231 Well Facility Project. Well CR-231 is a new well that replaces well CR-49, located in the Meadows near Castleview High School (Attachment B).  Well CR-231 could not be drilled on the same parcel as well CR-49 due to the constraints associated with access to the site.  This project consists of constructing a new metering and control facility for the newly drilled Well CR-231. Velocity submitted the lowest responsive bid for a total construction cost of $487,079. Staff also requests approval for a 10% Town-managed contingency of $48,707, for a total project authorization of $535,786.




Based on the Water Resources Supply-Demand Model, the high population growth trend, and the last two summer water demand seasons, additional water supply is needed to keep pace with increased water demands and to firm supplies. 


Well-231 was drilled as a replacement for Well CR-49; however, the parcel on which CR-49 is located was not a viable option for drilling.  CR-231 has been located on the same parcel as Well-149.  Well CR-49 was constructed in 1994.  In 2003, the original motor, pump, and at least two strings of drop pipe fell to the bottom of the well. All attempts to remove the pumping equipment failed.  Since then, the well has been producing sand, and staff is unable to rehabilitate the well.  However, there is currently pumping equipment installed above the lost section and some reduced water production is still being achieved.  The plan is to keep using the well until it is no longer a viable option.  In the meantime, CR Water has drilled CR-231, which should be able to achieve good production from the Arapahoe Aquifer.  Hydro Resources completed drilling the new well this past spring. 


This project will construct a new metering vault and electrical service needed to operate the well, see (Exhibit 1).  This project will also incorporate the controls for well CR-149 into the new control panel.  The current PLC that controls the operations of well CR-149 is at the end of its useful life. 


The request for bids for the project was sent to six qualified contractors.  Bids were received by three contractors, as summarized in the table below.  The Engineer’s estimate was $505,000.  The low bid was received by Velocity and is considered a responsive bid.

During the bidding process, staff identified damage to the existing 48” storm pipe that is located along the site.  This damage was caused by the drilling contractor during the sound wall installation.  The repair work has been incorporated into the facility contract, but Hydro Resources will reimburse the Town for the cost of the repairs.  The bid did not include some sidewalk repair that may be needed as part of the storm pipe repair.  Velocity has provided a cost of $4,250 for the sidewalk repair.


Budget Impact


Funding for this project is available in the approved 2020 Budget.  The project will be funded from the Well Redrills Account (Account No. 210-4275-442-76-53).  A budget transfer of $700,000 from the Water Supply Wells Account (Account No. 210-4275-442-75-39) will be done to fund this project.  This budget transfer will cover the cost of the Velocity contract and the negative balance of $135,164 in the account.  Velocity’s bid is $487,079.  Staff requests an additional $48,707 (Town-managed 10% contingency) be authorized for a total project authorization of $535,786.

Staff Recommendation


Staff recommends Town Council approval of the resolution approving the construction contract between the Town of Castle Rock and Velocity Constructors, Inc. for the construction for the CR-231 Well Facility Project in the amount of $487,079 plus a 10% Town-managed contingency of $48,707 for a total authorization of $535,786.
