Title
Consider Authorizing The City Manager To Approve A Contract With Gibson And Associates For The Repair Of Roadway Bridges At Six Locations Across The City In An Amount Not To Exceed $115,724.00.
Body
BACKGROUND:
The State of Texas conducts regular inspections of significant traffic bridges across the state to identify any deficiencies in the road deck or structure. These bridges include traditional bridges as well as multiple box culvert roadway crossings. These inspections yield a document referred to as a BRINSAP Report which provides thorough documentation of the bridge, deficiencies identified, recommendations to address bridge issues and a rating for the bridge.
Of the bridges located within the City, six locations were noted with issues that required correction. These corrections included repair of spalled concrete, cleaning/repairing deck joints and replacing bearing pads between the bridge beams and the bridge bent (cap on top of the piers). While none of the deficiencies are critical, repair of these issues will improve the long term safety and life of the bridge. A table of the bridges identified along with the deficiencies noted is attached.
The contract calls for a construction period of 60 days. The contractor has not submitted a sequence plan at this time, but it is anticipated that similar tasks will be conducted at various locations. One of the repair items, bearing pads, has a significant lead time associated with manufacturing and may impact the overall duration of the project. Road closures will be kept to a minimum with normally no more than one lane closed at a time in one direction. These closures are limited to between the hours of 9:00 am and 4:00 pm., Monday through Saturday. There are certain tasks that would benefit from multiple lanes being closed, namely joint repairs.
