<br />THE CITY OF SUNNY ISLES BEACH <br />PROJECT NO. 21-1011 <br />BUILDING DEPARTMENT RELOCATION TO ANNEX <br /> <br />Project No. 21-1011 November 2024 027450 -5 <br />B. The cold mix is to be installed one block at a time, not crossing any intersection, or a <br />maximum of 1,200 feet shall be completed before the Contractor may move forward with <br />his excavation work. Backfill, compaction and temporary paving is to keep pace with the <br />pipe installation. Written permission must be obtained from the Department and the <br />municipal agency permitting the work to allow greater lengths than 1,200 feet. Permitting <br />agencies may reduce the allowable limits in their permit, or for other unforeseen right-of- <br />way conditions. <br />C. Prior to completion of the work and within a maximum of 30 calendar days, the Contractor <br />shall remove the 1-inch of cold mix and surplus backfill. He shall replace it with the <br />specified compacted limerock base course and asphaltic within the specified working limits. <br />Municipal agencies permitting this work may accelerate the time for removal of the cold <br />mix, at their discretion. <br />D. The temporary pavement shall be maintained by the Contractor in a condition satisfactory <br />to the Department until its removal. Removal shall include any surplus backfill material. <br />Replacement of the temporary pavement with permanent pavement shall be made within <br />30 days. In replacing the temporary paving with permanent pavement, all work shall be <br />completed in sections compatible with specified traffic maintenance procedures. <br />E. Should the Contractor elect to install a suitable temporary hot mix asphaltic pavement, to <br />be left in place, in lieu of cold mix, a suitable credit for cold mix will be provided to the <br />Department when the hot mix asphalt is left in place and installed over properly compacted <br />limerock base course. This temporary pavement shall be incorporated into the specified <br />permanent pavement restoration as part of Type I paving replacement. <br />F. Sand seal on the limerock base course will not be permitted in lieu of temporary paving. <br />G. Unless otherwise approved by the Department, temporary paving shall be placed within <br />twenty-four hours following the completion of backfilling. <br />H. No payment shall be made for temporary paving work and the cost for such work shall be <br />included in the prices bid for other applicable items of work. <br />3.3 TYPE I PAVING REPAIR (Limerock Base - Asphaltic Concrete Surface) <br />A. Type I paving repairs shall be made with an 8-inch thick compacted limerock base and a <br />minimum 2-inch-thick asphaltic concrete surface, as detailed in the Standard Details. On <br />Public Works roads asphaltic concrete shall have a compacted thickness of 2-inch, placed <br />in a minimum of 2 compacted 1-inch lifts. <br />B. The backfill previously placed and compacted shall be excavated to the required depth <br />below the existing road surface and the existing paving shall be cut back beyond all <br />excavations, using an abrasive disc saw to trim the edges to straight and true lines, <br />minimum width for the limerock base shall be equal to the trench width plus 2 feet. Eight <br />inches of limerock base shall be placed in two layers; each layer compacted to not less than <br />98% density in accordance with Section 200 of DOT Specifications. During rolling, the base <br />shall be wetted down, as necessary, to secure the greatest possible compaction. After <br />rolling, the entire surface of the base shall be thoroughly scarified to a depth of not less <br />than 3 inches and shaped to conform to and be parallel with the existing surface, then <br />watered and rolled again. Rolling and watering shall continue until the entire depth of the <br />base is bonded and compacted into an unyielding mass. <br />C. If at any time the subgrade material becomes mixed with the limerock base course
