accounted for properly. The final adjusting change order shows a net increase of $56,016. The main reasons for this net increase are highlighted below. • The estimated amount of rock along the 18" sewer line, for which Change Order #4 was approved on December 2, 2013, was slightly larger than estimated ( +$23,880); • The estimated amount of rock along the 12" sewer line was larger than estimated ( +$167,353); • The amount of select fill (material brought in to replace rock removed or other unsuitable soil) needed was higher than originally estimated, due to increased rock excavation ( +$64,500); • Field conditions along the path of the 12" sewer line near a large pond required a more expensive construction technique than originally estimated ( +$36,764); • A portion of the 8" sewer line was cut from the originally bid scope of work, with approximately 700 linear feet left in the contract. However, when the unit price sheet establishing the contract amount was developed, the 8" gravity sewer line from the original bid was mistakenly left out. Therefore, the budget for the project was developed around an artificially low contract amount. The work was added back to the contract amount as Change Order #5 ( +$42,359.35); • Field conditions allowed for use of a much less expensive technology to cross three streams with the 16" water line (- $265,134). As mentioned above, these are the items that had the most influence on the amount of the adjusting change order. The substantial savings realized by changing the type of bore used on the water line should be noted. The net amount of these six items, along with the adjustments needed to zero all the rest of the line items in the contract, makes up the final adjusting change order amount. The amount of the final adjusting change order is within the Manager's dollar amount to approve, but approval of the additional money would exceed the project's budget. Therefore, the change order must be approved by the BOCC and a budget amendment is required to increase the budget to cover the additional cost. FINANCIAL IMPACT: This project currently has an overall budget of $5,013,046. The overall project budget will need to be increased by $56,016 to a total of $5,069,062 in order to cover the cost of the final adjusting change order. The additional funds to cover the change order would come from revenues received from the Article 46 Quarter -Cent Sales Tax. Budget Amendment #1 -C provides for the additional funds of $56,016 from Article 46 Sales Tax proceeds, and amends the Capital Project ordinance as follows: Buckhorn Mebane Phase 2 ($56,016) - Project # 30040 Revenues for this project: FY 2014 -15 Current Budget Oct. 7, 2014 Amendment FY 2014 -15 Revised Budget Alternative Financing $412561046 $0 $412561046 Appropriated Fund Balance $2001000 $0 $2001000 From General Fund $1351500 $0 $1351500 Article 46 Sales Tax Proceeds $4211500 $561016 $4771516 Total Project Funding $510131046 $561016 $510691062
