<br /> true, the total rock excavated for this 18" sewer line would be 10,850 cubic yards. When
<br /> compared to the original estimate of 3,825 cubic yards, the difference is 7,025 cubic yards.
<br /> The rock excavation line item is paid at $60 per cubic yard of rock excavated, so adding an
<br /> additional rock contingency of 7,025 cubic yards could potentially increase the construction
<br /> costs by $421,500. However, the request is only to add rock contingency to the project budget.
<br /> If the Contractor excavates less rock than estimated, this money will not be spent.
<br /> The other parts of the project each have their own rock allowance included in the original
<br /> project budget. The water line is approximately 75% complete and has used only a fraction of
<br /> its rock contingency. Construction of the 8"-12" sewer line has not yet begun, but it has its own
<br /> rock allowance, as mentioned above, and can use any remaining rock allowance not used on
<br /> the construction of the 18" sewer line, if necessary.
<br /> FINANCIAL IMPACT: This project currently has a construction budget of $4,016,546. Adding
<br /> the rock allowance contingency as outlined above would increase the construction budget by
<br /> $421,500. These extra funds would come from money generated by the Article 46 Sales Tax
<br /> and earmarked for infrastructure development. As a result of the additional money that would
<br /> be allocated towards this project, other Capital Investment Plan (CIP) projects which are to be
<br /> funded in the future by the Article 46 Sales Tax Revenue will have to be delayed or have their
<br /> scope reduced. Staff will be making proposals on next year's CIP budget and will suggest
<br /> specific project budget modification changes at that time. Budget Amendment #3-B provides
<br /> for the additional funds of $421,500 from Article 46 Sales Tax proceeds, and amends the
<br /> Capital Project ordinance as follows:
<br /> Buckhorn Mebane Phase 2 ($421,500)- Project# 30040
