DEC BOOK. F- JE. 6've Commissioner Scurlock asked if Marshall, McCully & Associates had ever built a bridge for us, and Public Works Director Jim Davis advised that they are doing this in a joint venture with a large firm that specializes in bridges. Commissioner Scurlock wondered why Lloyd & Associates wasn't ranked higher after they did such a good job on the bridge over by the country club. Director Davis explained that they were ranked #3 out of 23 firms, but the thinking was that we need to go with the eshto-beam girders more so than the hollow -core, pre -stress slabs. The DOT has developed problems with the hollow -core, pre -stress slabs, which has been the typical type of bridge that Lloyd & Associates has desicrned for us. Lloyd & Associates has indicated they can do the eshto-beam design, but he believed the committee felt that some of these other firms had a better handle on that type of construction. Commissioner Scurlock felt that makes a big difference, because generally he was not too ecstatic about joint ventures since they usually end up with two overheads, a flow-through and a percentage on top of the other firm's work. Director Davis emphasized that if we find that in the negotiations on the contract, we will go to the #2 ranked firm, Mosby & Associates, who has designed about 7 bridges in this general area, but not in this county. Administrator Chandler reported that after the Board gave approval last Tuesday to go ahead on the repair/replacement of the bridges that were identified by the DOT to have severe corrosion, staff has determined that two of the Oslo Road bridges, the ones east of 58th and 43rd Avenues, definitely will be replaced, while a third one east of 74th Avenue is a likely candidate as well. They feel the one on Winter Beach Road can be repaired. Consideration was given to having the bridge replacements done on an emergency basis by the same construction firm that is replacing 46
