ESTIMATED COSTS The project is summarized in Table ] below. An itemized breakdown of the construction costs are presented in Appendix B. The construction costs summarized in Table 1 have been divided into project assessable costs and trunk eligible costs. The project assessable costs are those costs necessary to provide service to the project area alone. The trunk eli~.'ble costs represent those costs associated with oversizing certain elements of the project to serve adjacent areas outside the project area. In this project, the difference in cost between an eight inch and twelve inch watermain is considered trunk eligible as would the extra depth of the sanitary sewer down Helium Street N.W. to service the area to the north. In addition to construction costs, Table ! contains overhead costs on the amount of 30% of the construction costs. Overhead costs include, but are not limited to engineering, construction staking, inspection, fiscal, legal, administrative and contingency costs. An estimate of these costs is as follows: Engineering 10% Staking and Inapection 7% Fiscal and Legal 3% Administration 5% Contingencies 5% In addition, acquisition of the Jones easement has been added to the construction and overhead costs to obtain the resultant total project cost. The easement acquisition cost has been estimated based upon right-of-way acquisition settlements on similar City projects. The above easement acquisition cost is based upon it being obtained through negotiation and does not anticipate the costs of eminent domain procedures.
