1987.10.14_TC_Minutes_Speciali I TOWN OF HIGHLAND BEACH, FLORIDA Minutes of Meeting of Town Commission SPECIAL MEETING Wednesday, October 14, 1987 3:~l0 P.M. The Special Meeting of the Town Commission was called to order by Com- missioner John J. Basso in the Town Commission Chambers at Town Hall. Also present were Town Commissioners David T. Robinson and Robert F. Scholz. Mayor Betty Jean Stewart and Vice Mayor Mary Louise G. Blosser were absent. Present also were Town Attorney Thomas E. Sliney, Town Manager Hugh D. Williams, Town Clerk Mary Ann Mariano and members of the general public. Commissioner Basso noted that the purpose of the Special Meeting was two-fold, the first matter concerning a Change Order on the Bel Lido Bridge Wingwall Project. The second matter to be discussed would be the receipt of the Town's final Tax Certification from the Property Appraiser's Office. The Town Manager explained the problems which have been encountered by the contractors on the Bel Lido Bridge Wingwall Project. The problems encountered by the contractors are contained in a letter from Russell • and Axon, Inc., the engineers on the project, dated October 7, 1987. Attached to that letter is a cost estimate to repair the problems. Both documents are attached to these minutes and incorporated herein by reference. Ken Schenck, Vice President, and Charles Perron, Chief Engineer from Russell and Axon were present and presented a graphic presentation to the Town Commission regarding the difficulties in continuing the project. Mr. Perron further noted that he felt that the Town should have a load limit on the bridge and a notation of such limit. It was noted that the Town had implemented a load limit on the bridge and that a sign did exist indicating such 15 ton limit. It was noted, however, that recently there had been concrete trucks, garbage trucks, etc., travelling over the bridge in excess of 15 tons. Stricter enforcement of the ton limit will be directed. Mr. Williams noted that he would see to it that if in fact the weight limit sign was not in a proper location, it would be moved. Substantial discussion took place regarding the methods by which the contractors could pursue the problems faced. The engineers noted that they were proposing to put dead man aprons filled with concrete behind existing wall and tying same back. There was substantial discussion regarding the necessity of tying back the dead man. The engineers noted that without this phase being done, there was no guarantee that the bridge would not vibrate and require additional work in the future. `-.~ Town Commission Special Meeting October 14, 1987 Page 2 of 3 • It was noted that the concrete filled dead man would cost approximately $4,000. with the anchoring and tying back of same costing an additional $10,980. Commissioner Scholz stated that he was not convinced that the anchoring of the system for the sum of $10,980. was necessary, however, would agree to same if that was the desire of the other Commissioners. Commissioner Robinson noted that he did not feel the Town should take the chance of having the walls fall in when the Town could prevent same at this point for the additional $10,980. Mr. Williams further noted that originally, the Town was anticipating the expenditure of $125,000. on the repair of the Bel Lido Bridge, and that even with the proposed $14,980, change order, the cost was still well below this amount. MOTION was then made by COMMISSIONER ROBINSON/COMMISSIONER SCHOL~ to approve the proposed Change Order for the Bel Lido Bridge Wingwall Project in an amount not to exceed $14,980. This MOTION carried unanimously with favorable votes. The engineers noted that with the the completion of the job by one • Mr. Williams noted that the Town funds in order to remove some of some of which would be saved and feasible. change order, this would only delay to two days. would be spending a minimal amount of the vegetation from the bridge area, placed behind Town Hall if economically The Town Commission noted that they felt the contractors had done a good job on the bridge at this point. Commissioner Robinson did point out that there had been no flag man present when only one lane was being utilized and requested attention to this matter. The Town Commission then briefly discussed ways to slow down the drivers when going over the bridge. Mr. Williams recommended that the Town install a speed bump at the bridge approach, however, the Town Commission would not consider such a bump without public comment on the matter from the residents of Bel Lido. It was determined that the Town should place an additional speed limit sign at the bridge approach to limit the speed to 20 mph. This recommendation will be further addressed at the Town Commission October 27, 1987 Workshop Meeting. Mr. Williams then stated that the Town had received its Certification of Final Taxable Value from the Property Appraiser. After the time allowed for appeals to the County, the Town's appraised value was decreased by approximately $2,000,000. or .41$. This will result in $5,576. less tax funds coming to the Town on the approved 2.7931 mills as adopted in the n LJ Town Commission Special Meeting October 14, 1987 Page 3 of 3 Town's budget. It was the Town Manager's recommendation that the Town not change its existing tax rate which would require a full formal procedure for change. The Town Commission concurred in this recommenda- tion and directed that the Certificate be signed and returned to the Property Appraiser's Office based on the adopted millage. There being no further business to come before the Town Commission at this Special Meeting, same adjourned at 3:45 P.M.

Established in 1920 October 7, 1987 Mr. Hugh Williams Town Manager Town of Highland Beach 3614 S. Ocean Blvd. Highland- Beach, Florida 33431 Subject: Bel Lido Bridge Abutment Renovation Change Order ~l'1. Dear Mr. Williams: As happens in construction, the Contractor encountered considerable debris under the Bel Lido Bridge while trying to drive the aluminum piling for the curtain wall. As he is not affecting the entrance to the island, we see no reason to stop progress but, have notified them of their delay, a copy of which was sent to you on 9/25j87. As the field work progressed, our resident inspector has started to report that several problems are evident concerning the existing bridge abutment, which could not be seen at the start of the project. After cutting down the brush along the roadway, large voids were observed under the new bridge approaches. Initially we determined that storm water was diverted into this area off the street which caused the undermining. Later we found that there is a sprinkler system in the areas, which also adds to the undermining problem. However, after standing on the bridge and working under the bridge, a third major factor was discovered. Heavy vehicles crossing the bridge create a major vibration transmitted into the earth below the apron of the bridge, which is the same area mentioned above. This is causing the entire old abutment to vibrate which is causing us concern for the protection of the new containment and sheeting. After discussing several • possible solutions, the Contractor has submitted the enclosed detail and cost to tie-back the walls which will maintain the integrity of the new structure.

Additionally, while endeavoring to insert the tie-backs and anchors into the existing concrete piling, the concrete splinters, denoting deteriorating of the bulkhead ae well. Thus our detail to tie-back the walls with cable. It is proposed that the Town remove the plants, palms, and sprinkler system so that they can be used in another location. Other growth will be cut, but not the roots removed, as we feel that they may be the only thing holding the fill together, until the new structure is complete. Additionally, we propose that the voids be grouted, and then all ` four sides covered with wire-meshed concrete to divert storm water into the canal, directly. To protect your investment, we feel that these additional alterations are necessary. We will be pleased to explain our findings to the Town Council to obtain their approval for these changes. However, if there are any questions, please da not hesitate to contact our office. Very truly yours, Enclosure cc:File Russell & Axon, Inc. Charles H. Perron, P.E. Chief Engineer • .. s.
