<br />E. Vibrate concrete masonry paving units into leveling base with a plate vibrator capable of <br />a 3,500 to 5,000 lb. compaction force. Perform this operation on installed areas of <br />paving at end of each day or before any rain. <br /> <br />F. Fill joints after vibration with sharp sand as specified in this section. <br /> <br />G. Finish grade to allow for settlement: finish elevation for ungrouted, mortarless block <br />pavers shall be 1/8" higher than adjacent concrete. In lawn areas as indicated on <br />drawings the finish elevation at the pavers shall be 1" higher than the finished grade of <br />lawn. <br /> <br />3.02 GENERAL PAVER INSTALLATION <br /> <br />A. Do not use pavers with excessive chips, cracks, voids, discolorations or other defects <br />which might be visible or cause staining in finished Work. <br /> <br />B. Cut pavers with motor-driven saw equipment to provide clean, sharp, unchipped edges. <br />Cut units to provide pattern shown and to fit adjoining work neatly. Use full units <br />without cutting. <br /> <br />C. Set pavers accurately to lines, levels and in patterns as indicated on drawings and with <br />uniform joints of width indicated. Back cut all pavers as required to accommodate Work <br />of other trades located in setting beds. <br />D. Tolerances <br /> <br />1. Maintain surface plane for finished masonry paving not exceeding a tolerance of <br />1/8" in 10' when tested with a 10' straight edge. <br /> <br />E. Provide edging as indicated on plans. Install edging prior to placing masonry paving <br />units. <br /> <br />3.03 CUTTING PAVER BLOCKS <br /> <br />A. Layout paver and adjust brick coursing such that no brick shall have to be cut along, or <br />parallel to, its long axis, unless approved by Consultant. <br /> <br />B. Layout pavers and adjust brick coursing such that no brick shall be cut to less than half <br />its length across its long axis. If it is unavoidable to cut bricks smaller than one-half <br />(1/2) their long dimension due to the necessity of maintaining the paving pattern, the <br />Contractor shall notify the Consultant and request their permission to proceed with the <br />cutting. <br /> <br />3.04 REPAIR, POINTING, CLEANING AND PROTECTION <br /> <br />A. Remove and replace paver units which are loose, chipped, broken, stained or otherwise <br />damaged, or if units do not match adjoining units and install in same manner as original <br />units, with same joint treatment to eliminate evidence or replacement. <br /> <br />B. Protect paver block installations from deterioration, discoloration or damage during <br />subsequent construction and until acceptance of Work, in compliance with <br />recommendations of installer and paving unit manufacturer. <br /> <br />PAGE 105 OF 130 <br />BID No. 08-10-01 <br />
