The Audubon Bridge Task Force met with Mr. Gerwig and Ms. Tropepe on Tuesday May 12th. He explained that the current bridge was built in 1957 and in 1999 the Town replaced the wing walls at the four corners. The wing walls are in good shape and are only 15 years old. According to Mr. Gerwig they should last until at least 2040. Bridge Design has designed the new bridge with all new wing walls. The bridge is estimated to cost $992,000, if the current wing walls are used then there could be a savings of $150,000 to $160,000. The walls may or may not need shoring up. The other benefit of using the existing walls is that there would be 32-36 less piles driven and this would save at least a couple of months off the schedule and would be less noise and vibration for the residents. The only question is do the walls need strengthening and at what cost. Mayor Pro Tem Isaac explained that the Town had already saved $122,000 by not running the water line all the way from Lands End Road to Spoonbill Road. There is a proposal to only replace the water line at the bridge itself which saves the Town $40,000 to $50,000. The Commission received a letter from Mock, Roos advised them to at least replace the asbestoscement pipe west of the bridge and the cast iron section at the bridge. Mr. Gerwig stated they did have the plans for the wing wall construction however they did not have the as-builts for the project. They did bring in a geo-technical engineer to evaluate the wing TCOM Minutes 05-15-15 Page 1 walls for stability. Results of their analyses show that the existing wall does not have the capacity to resist the design load cases that would be required by the current design specifications. The strengthening will likely result in a cost savings compared with the full replacement. The most effective cost saving would have to be arrived at with the engineer of record. They are not able to estimate the savings at this time. Once reinforced, the wall will have a lesser service life than the new bridge by at least 15 years. Changes to the wall will not require any new permits. However, they will need more time to arrive at the cost for strengthening the wing walls. They estimate they need several weeks. Mr. Gerwig said there was a third option and that was to do nothing and see how the walls held up during the construction phase. Town Attorney Davis noted that the engineer of record would have to agree to any changes to the current design of the bridge. Mayor Cheifetz explained that the Commission was now tasked with directing Mr. Gerwig and Ms. Tropepe on how to proceed. There are three options available, do nothing and leave design as is, strengthen the wing walls or replace the wing walls according to the current plan. Mr. Gerwig suggested the first option should be to work with the engineer of record and see if he would agree to the strengthening and at what cost. Ms. Tropepe was concerned that the methodology the engineer of record would use may cost more than the replacement of the wing walls. Mayor Cheifetz asked the Commissioners for their opinion, after discussion the decision was made to see if the engineer of record could attach the existing wing walls to the new bridge design, if not then they would fall back to the original design. PUBLIC COMMENTS: Mr. De Jong was concerned with the difference between a strengthened wall and the new walls which would have the same life as the new walls and asked the Commission to move forward with the current design. He was also concerned with asbestos pipe. Ms. Hedberg is worried about structural damage to her home and pool from the pile driving. So she suggested the options whereby less piles are used. Mr. Gottlieb asked about the contractor, and he was told that the Town has signed a contract with Drawdy. Mayor Cheifetz stated that direction is given to the engineers to work with the engineering firm to see if there is a way to connect the existing wing walls to the new bridge. Mr. Gerwig and Ms. Tropepe were asked to present their findings at the May 26th meeting. Mr. Roder was concerned that pipes underneath the bridge are in rough condition. DISCUSSION OF WATER LINE: Ms. Tropepe discussed the original option to replace the water line from Lands End Road to Spoonbill. From a Value Engineering standpoint they worked with Johnson Davis to develop an alternative. There is some asbestos cement pipe and cast iron pipe. The alternative is to replace the waterline at the bridge only since this is primarily a bridge project not a water department project. The estimated cost savings range from $45,500 to $50,500. Town Manager Stumpf explained this was funded by the utility. The Commission by consensus agreed to only replace the water line at the bridge. 2 TCOM Minutes 05-15-15 The meeting was adjourned at 10:33 p.m. These minutes were presented to the Town Commission on Tuesday May 26, 2015 for approval. _________________________ David S.
