Body
________________________________________________________________________________
Executive Summary
Maintaining the Town’s bridges is important for public safety, travel efficiency, and as a means to extend the useable life of the bridge structure. This overall project is the annual Bridge Maintenance Program for the Town’s bridges and is intended to preserve the Town’s bridge infrastructure. The purpose of this item is to request approval of Town Council to enter into a construction contract (Attachment A) with T & M Construction, LLC to perform bridge maintenance activities.
The Town of Castle Rock annually budget’s for the Bridge Maintenance Program, in line with the Public Works Department’s Strategic Asset Management Plan, to perform needed maintenance to the Town’s bridges. Maintenance work generally consists of deck wearing course overlay, deck repairs, girder & abutment repairs, bridge rail repairs, expansion joint repair, and approach rail repairs. Maintenance work will be performed on the Front Street Flyover Bridge over the Union Pacific Railroad (UPRR), as well as the Perry Street Bridge over Sellers Gulch. Maintenance locations activities are indicated on the 2019 Bridge Maintenance Program map (Attachment B).
Notification and Outreach Efforts
Staff has developed specific public coordination outreach to ensure that residences and businesses will understand construction impacts and how this may affect access to individual businesses and residences. Public outreach will occur in numerous forms such as; 1) Town newsletters, 2) HOA mediums such as newsletters, 3) Town social media, 4) Press releases, 5) Town’s web site and others, and 6) Variable Message Signs. Residents and businesses will be notified of actual dates that work is to be performed, and traffic control plans will be developed and managed to ensure worker and public safety.
History of Past Town Council, Boards & Commissions, or Other Discussions
Staff presented the Bridge Rehabilitation for Front Street Flyover and Perry Street over Sellers Gulch project to the Public Works Commission on February 4, 2019. Their recommendations will be presented to Council at the February 5, 2019 Council meeting.
Discussion
Castle Rock’s bridges that are at least twenty feet in length are inspected every two years through CDOT’s Off-System Bridge Inspection Program, in accordance with the requirements of the National Bridge Inspection Standards (NBIS). Staff has reviewed these documents in the selection of bridges to be considered for the 2019 Bridge Maintenance Program. Staff selected the Front Street Flyover Bridge to repair areas of deterioration on girders and the abutments. Additionally, staff selected the Perry Street Bridge to repair areas of deterioration on the abutments, expansion joints, sidewalks (including the decorative pavers), and the bridge deck.
The Town contracted with Felsburg Holt & Ullevig (FHU) for engineering design services on the bridges. Plans and specifications were posted on Bidnet November 6, 2018 to solicit competitive bids. The Town received three (3) bids ranging from the low bid of $318,382 to $399,483 on December 6, 2018.
The low bid was checked for accuracy, references were checked, and all documents were reviewed for contract compliance. Staff believes that the recommended bidder is qualified to perform the work associated with the respective maintenance contract. A summary (Attachment C) shows the individual bids, and the contractors. Pending approval, construction is expected to take place during April/May of 2019.

The 2019 budget for the Bridge Rehabilitation Project is $380,000. This expense has been budgeted and will be expensed to the 2019 Bridge Maintenance Program account 120-3140-431-40-42. The requested encumbrance is $318,382, plus 10% Town managed contingency of $31,918 for a total encumbrance of $350,300. The following is a brief summary:
