Emergency Construction Services to Repair Riverbank Damage and Boat Landing at the Riverwalk:
On Wednesday, March 20, 2013, there was a major collapse of the riverbank north of City Mills, immediately behind Chase Homes. The area impacted is approximately 900 ft. in length and involves approximately 300-400 ft. of the Riverwalk. There are also two large Georgia Power transmission towers in the affected area. The area has been closed to the public and Public Works is in the process of installing a fence around the area to keep spectators away from the site. Due to the damage, the Riverwalk will be closed from the 23rd St. Pavilion to City Mills indefinitely. The instability of the river bank places more of the Riverwalk, and potentially the transmission towers, at jeopardy if the bank is not stabilized in a timely manner. The closure of the Riverwalk also represents an inconvenience to the Public who routinely use the area. These conditions constitute an emergency situation and warrant moving forward accordingly.
Scott Bridge Company, who is currently under contract with the City for construction services related to the 14th Street Pedestrian Bridge, will be the contractor performing the emergency repairs. On the morning of Thursday, March 21, 2013, City staff met on site with Jacobs Engineering, the City’s engineering consultant, and representatives from Scott Bridge, to assess the damage and develop a strategy to move forward. Scott Bridge will work with the City’s consultant, Jacobs Engineering, on designing and implementing a riverbank stabilization plan and repairs to the Riverwalk. Additionally, Scott Bridge has access to material at another construction site that will require disposal; this material could be used for bank stabilization resulting in a significant savings for the City. The design-build approach would provide for the most timely stabilization and repair of the damage, preventing further damage to the Riverwalk and allowing it to be reopened to the public. The exact cost of the stabilization and repairs cannot be estimated since a design has not been completed. However, Scott Bridge has agreed to contract for time and materials on the project. The City's Project Managers can closely monitor this work and the expenses associated with the project.
Additionally, the boat landing behind the Trade Center has a large section of the ramp that has collapsed. The damage represents a hazard to the public. The boat landing is also the take out point for Whitewater operations scheduled to begin on Memorial Day. As stated above, Scott Bridge Company, currently under contract, will be utilized to perform the construction repairs, and will be in the area making ramp improvements within the next few weeks. The preliminary estimate for replacing the ramp and to install a small retaining wall to prevent erosion is $65,000.
The City Manager approved the emergency purchase on March 21, 2013.
