The crack <br />filling and bituminous repairs are proposed to be completed by <br />the City's Street Maintenance Department as routine maintenance. <br /> <br />It is anticipated that the normal life of seal coating with a <br />Class C aggregate is approximately five (5) years. This will <br />wary somewhat, depending on the type and amount of traffic. <br /> <br />~STIMATED PROJECT COSTS <br /> <br />~e estimated quantities and costs are provided on the following <br />pages in tabular form for each of the improvement projects. <br />Costs consist of the construction cost and project overhead cost <br />which includes engineering, administrative, contingencies and <br />financing. The overhead costs are estimated at twenty percent <br />(20%) of the construction cost. Following is a breakdown of the <br />overhead costs: <br /> <br /> <br />
