to be in satisfactory condition. In the remaining project areas, the <br />bituminous surfaces are showing evidence of deterioration and are in <br />need of seal coating. <br /> <br />PROPOSED IMPROVEMENTS <br /> <br />To extend the life and renew the surface of the existing paved <br />streets, it is proposed to seal coat the streets with a Class C <br />aggregate in accordance with Specification No. 2356 of the Minnesota <br />Department of Transportation's Standard Specification for Highway <br />Construction, 1983 Edition. <br /> <br />The proposed work would consist of crack filling and patching, appli- <br />cation of a bituminous material, and application of an aggregate which <br />is 3/8 inches in size and smaller. The crack filling and bituminous <br />repairs are proposed to be completed by the City's Street Maintenance <br />Department as routine maintenance. <br /> <br />It is anticipated that the normal life of seal coating with a Class C <br />aggregate is approximately five (5) years. This will vary somewhat, <br />depending on the type and amount of traffic. <br /> <br />ESTIMATED PROJECT COSTS <br /> <br />The estimated quantities and costs are provided on the following pages <br />in tabular form for each of the improvement projects. Costs consist <br />of the construction cost and project overhead cost which includes <br />engineering, administrative, contingencies and financing. The over- <br />head costs are estimated at twenty percent (20%) of the construction <br /> <br /> <br />
