Title
Resolution Approving Additional Funds for a Construction Contract with T&M Construction, LLC, for the Bridge Rehabilitation for Front Street Flyover and Perry Street Over Sellars Gulch Project
Body
________________________________________________________________________________
Executive Summary
Staff is recommending approval of the attached resolution (Attachment A) increasing the existing encumbered amount of the Bridge Maintenance Service Contract by $34,000. The additional scope for bridge maintenance at the Perry Street Bridge over Sellars Gulch has been assessed, and is deemed necessary by staff to provide for additional repairs that were uncovered during initial repair work. The existing encumbered scope of work is approved under the Bridge Maintenance Acct. #120-3140-431-40-42, for $350,300. The requested increase amount is $35,000 for a total project amount of $385,300. There are sufficient funds in the overall 2019-maintenance budget, account 120-3175-431-40-35 that is available to cover this increase.
Discussion
Public Works staff has conferred with the Finance Department for the reallocation of funds. The Finance Department is in agreement with the remedy of transferring funds from one account to another to cover this increase.
During the deck preparation for the epoxy overlay, several locations were discovered that required repair to ensure that the deck is structurally sound.
During repairs of the sidewalk, it was determined the existing brick pavers had deteriorated to the point that they were not usable. The solution was to go with a colored concrete that provided a similar aesthetic look while improving the durability of the sidewalk.
Repair of the cracking and spalling of concrete under the bearings at the south abutment required the removal of roughly two square feet of concrete in the abutment wall at each bearing location. During this rehabilitation work, it was discovered that the existing anchor bolts were of inadequate length. This needed to be addressed to ensure the bearing plates were structurally sound.
CDOT evaluates all public bridges every two years. The intent of this program is to document the present condition of each bridge and to report the findings to the State and to the Town. This request is for additional funds to cover repair costs associated with deficiencies not identified in the initial evaluation of the bridge.
Budget Impact
This increase of $35,000 is available in the maintenance account 120-3175-431-40-35 within the Transportation Fund.
Staff Recommendation
Staff recommends the approval of additional funds to cover repair costs on the Perry Street Bridge.
Proposed Motion
“I move to approve the Resolution as introduced by title.”
