11 1 Michael Talbert said rock allowance is standard for these types of contracts. 2 Commissioner McKee said it is not unusual to find this much rock when digging in Orange County. 3 Commissioner Gordon clarified that the funding would not be spent if there is no more rock 4 encountered. 5 Kevin Lindley said that is correct. 6 Commissioner Gordon noted that the water line is 75 percent complete and has only used a fraction 7 of its rock contingency. She asked how much has been saved here. 8 Kevin Lindley said the original rock contingency for the water line was about 900 cubic yards and 9 only 200 yards have been encountered. He said this is not enough to cover the anticipated overage. 10 Commissioner Rich asked how a rock allowance is estimated. 11 Kevin Lindley said staff looked at similar projects in the area and estimated the costs based on this. 12 He said bids also came in higher than expected, so there was no padding added to the rock allowance. 13 Michael Talbert said this is the second or third line that has been installed in this area, and it is the 14 first to exceed the rock allowance. 15 Commissioner McKee referred to a similar project that did borings and found one narrow band of 16 rock. 17 Commissioner Dorosin asked if there was an alternative. He said it seems the project could not go 18 forward if the Board says no. 19 Chair Jacobs said Carrboro High School was just like this and had a shockingly high cost because 20 of rock. 21 Chair Jacobs asked during what hours the crushing of rock happens. 22 Kevin Lindley said the crusher runs during normal operating hours. He said the crew arrives around 23 7:30 am, but time is allowed to warm up the equipment. He believes it is run between 9:00 am and 4:00 24 pm. 25 Chair Jacobs asked how long the project will continue. 26 Craig Benedict said staff found it would take about three hundred truckloads to remove the rock. 27 HE said the crusher avoids this by crushing the rock and mixing it to put back in as fill later on. He said the 28 work with rock blasting does take longer and this western section of the project is about a month and half 29 from completion. He said it would probably be about 3 to 4 months of work in the middle Gravelly Hill leg of 30 the project. 31 He said the water line is going well, but sewer lines have to go deeper. This is the reason for the 32 additional rock. 33 Chair Jacobs asked if the public in that area has been educated about this process. 34 Craig Benedict said signs have been put up in this area, which is mainly farmland. 35 Commissioner Rich said her house would shake when OWASA was exploding rock to put in the 36 new pipeline across Estes. She hopes good notice is being given to residents. 37 Kevin Lindley said there have only been a couple of houses close enough to detect it on this project. 38 He said most of these residents have already been approached regarding easements, so they are aware of 39 what's going on. He said the contractor in charge of the blasting is very responsible. 40 41 A motion was made by Commissioner Price, seconded by Commissioner McKee to approve Budget 42 Amendment#3-B by adding $421,500 in rock contingency to the Buckhorn Mebane Phase 2 Utilities project 43 construction budget. 44 45 VOTE: UNANIMOUS 46 47 a. Redesigned County Logo 48 The Board reviewed and considered options for a redesigned County Logo as recommended by the 49 Review Committee for the County Logo. 50 Michael Talbert said this item is coming forward, after discussion at a work session, with four 51 options. He noted that these options are included in the packet and are labeled A, B, C, and D. He asked 52 the Board for indication of their preference.
