Pool Construction (2-9011) <br />Plana for the pool shall be drawn to a scale of 1/4 in. to 1 ft. and for the pool <br />equipment room 1 in. to 1 ft. <br />Reinforced concrete or equivalent. <br />The finish color shall be white. <br />Pool free from projections or recessed areas. <br />B. <br />Geometry for pools without Diving Boards, Fig. 2-9013(a)(3). If diving boards are present, <br />see 2-9013 & 9017 <br />Max radius at shallow end is 1 ft. <br />Max. depth at shallow end is 3 1/2 ft. <br />Max. slope from shallow end is 1:10. <br />Max. slope from slope break to drain is 1:3. <br />min. springline around pool is 2 1/2 ft. <br />Min. width at drain is 15 ft. <br />min. Length for pools less than 6 ft. deep is 15 ft. <br />Safety rope fasteners (flush mounted) required at 4 1/2 ft. <br />Dimensional construction tolerance is I 2 in. <br />Dimensional tolerance on nonadjustable perimeter overflow systems (gutters) is + 1 /8 in. <br />Drainable through main drain at deepest point of pool. <br />C.
