In locations where pavers are set with the pedestrian area construction tolerances are to be met. The following are the tolerances published by the Interlocking Concrete Pavement Institute as a result of the project identified below: https://www.access-board.gov/research/completed-research/dimensional-tolerances/introduction Interlocking Concrete Pavement Institute Construction Tolerances for Segmental Concrete Pavements Setting Bed Joint Widths Construction Tolerances Materials Sand setting beds Joint width between adjacent 1/16 in. to 3/16 in. for concrete pavers units and paving slabs (See Figure I) Attribute Segmental Concrete Paving Construction Placement & Products & Characteristics Surface Tolerances Joint or bond lines All segmental concrete paving Maximum ±1/2 in. horizontal products: Horizontal deviation deviation from either side of a 50-ft. string line pulled over a joint or bond line Laying Pattern Concrete Pavers: 90 degree herringbone Surface smoothness All segmental concrete paving Maximum 1/8 in. products: Variation in height between adjacent units (lippage) Surface flatness All segmental concrete paving ±3/8 in. over 10 ft., products: Surface tolerance noncumulative 606.04 MEASUREMENT AND PAYMENT THE FOLLOWING PAY ITEMS ARE ADDED: Pay Item Pay Unit CONCRETE SIDEWALK, 4” THICK SQUARE YARD CONCRETE SIDEWALK, REINFORCED, 6” THICK SQUARE YARD HOT MIX ASPHALT DRIVEWAY, 2” THICK SQUARE YARD DETECTABLE WARNING
