TABLE 6 <br />Nonstructural Concrete Flatwork <br />Minimum Thickness <br />in. <br />4 <br />Presaturation <br />Presoak to 12 inches <br />Reinforcement <br />No. 3 at 24 inches on centers or <br />6x6 No. 6 x No. 6 WWM <br />Crack Control Joints <br />Saw cut or deep open tool joint to a <br />minimum of 1/3 the concrete thickness <br />Maximum Joint Spacing <br />5 feet <br />Pedestrian Concrete Pavers <br />Concrete pavers should be installed per manufactures recommendations. The following are considered <br />minimum recommendations for the concrete pavers and are not meant to supersede more restrictive <br />manufactures recommendations. Concrete pavers should be designed to be underlain by a minimum of <br />1 inch of leveling sand over a minimum of approximately 4-inches of compacted aggregate base. <br />The subgrade should achieve a minimum relative compaction of 90 percent. The base material <br />should be compacted to achieve a minimum relative compaction of 95 percent. Base and subgrade <br />materials should be moisture -conditioned to a relatively uniform moisture content at or slightly over <br />optimum. <br />Tile Pavers <br />Tile pavers should be installed per manufactures recommendations. The following are considered <br />minimum recommendations for the tile pavers and are not meant to supersede more restrictive <br />manufactures recommendations. Tile pavers should be designed to be underlain by a minimum of 4 <br />inches thick concrete reinforced with No. 3 rebar at 24-inches on center each way or 6x6 No. 6 x No. <br />6 WWM over a minimum of approximately 4-inches of compacted aggregate base. <br />The subgrade should achieve a minimum relative compaction of 90 percent. The base material <br />should be compacted to achieve a minimum relative compaction of 95 percent. Base and subgrade <br />materials should be moisture -conditioned to a relatively uniform moisture content at or slightly over <br />optimum. Refer to manufacturer's specification if a vapor barrier should be installed. <br />4.7 Swimminz Pool <br />The proposed pool and associated improvements should be constructed in accordance with the <br />attached Figure 4, Geotechnical Guidelines for Swimming Pool Construction. Pool excavation will <br />occur in newly placed compacted fills and is anticipated to be relatively uniform. Consideration <br />should be given to the high expansive potential of onsite soils in design of the pool, and associated <br />decking. Also concrete in contact with onsite soils should be designed in accordance with the <br />So/negligible category of ACI 318R-14 Table 19.3.2.1. <br />Project i y ouncil 18 — 840 1 3 , 2021 <br />
