MEMO
To: Honorable City Council
From: James Pease, Public Works Director
Date: 04/26/2024
Subject: Stanislaus River Bike/Pedestrian Bridge
RECOMMENDED ACTION:
Approve the purchase of a replacement pedestrian truss bridge segment from Contech Engineered Solutions LLC in the amount of $107,565 (funding source: Insurance Provider).
BACKGROUND:
On October 22, 2023, a large tree located on the Ripon side of the Stanislaus River fell onto a segment of the Stanislaus River Bike/Pedestrian Bridge causing significant damage. The tree was removed immediately to relieve the weight and a structural engineer was contracted to perform an assessment. According to the analysis performed by the structural engineer, the bridge in its current condition must remain closed for the safety of the public due to the risk of failure.
DISCUSSION/ANALYSIS:
City staff, the consulted structural engineer and multiple contractors have evaluated several different repair options including temporary shoring to provide a temporary opening, permanent in place restoration through the use of heat treatment and added structural reinforcement. After this evaluation process the final recommendation from the structural engineer is to replace the damaged bridge segment.
The attached quotation is from the original bridge manufacturer Contech Engineered Solutions LLC (Contech) and it includes a painted replacement bridge segment delivered to the City of Ripon. There is an 8 to 10 week lead time on the final submittal package from Contech and the current production completion estimate is November 2024.
The next step will include a contract to perform the necessary clearing, bridge segment removal/installation, concrete deck placement and tree clearing and removal to eliminate future hazards concerning the bridge. Staff continues to work with the Army Corps of Engineers and anticipates all environmental and procedural measures to be resolved by the estimated delivery date.
FISCAL IMPACT:
The City is processing all associated expenses necessary for replacement of the bridge segment through its insurance provider. The attached quotation from Contech in the amount of $107,565 doesn’t include tax although tax will be included on the final invoice.
