Building Codes: Model: International Building Code 2012 Concrete: American Concrete Institute ACI 318-11 American Concrete Institute ACI 350-06 PG2. The construction documents indicate design of a completed reinforced concrete structure. The structural details have been prepared based on cast-in-place concrete methods. If alternate means and methods of concrete placement are employed that may alter the completed project, the contractor must submit proposed revisions and signed/sealed calculations to the Architect/Engineer for approval prior to fabrication or construction. PG3. The pool structure has been designed to withstand all anticipated loadings under both full and empty conditions in accordance with the criteria of ACI 350 for a non-jointed structure. PG4. During construction the pool structure should not be completely filled with water with no backfill present. If the pool is to be filled with water with no backfill, all walls greater than 6'-0" in height must be laterally braced at maximum intervals of 2'-0" on center. Lateral bracing shall be placed within 2'-0" of the top of the wall. PG5. The pool shell has not been designed to withstand any surcharge loading from adjacent structures. Inform engineer immediately if adjacent structures are close to the pool structure. HYRDOSTATIC RELIEF VALVES HV1. HRV = Hydrostatic Relief Valve. HV2. The hydrostatic relief valves are part of the pool shell design, and are intended to balance buoyant forces caused by groundwater that is higher than the pool bottom when the pool is empty. The hydrostatic relief valves must remain open and in operation whenever the pool is empty. If the hydrostatic relief valves are not operational, significant deflection of and damage to the pool shell structure is possible. Contractor is responsible for control of groundwater levels during construction. Refer to the project geotechnical report for additional information. POOL SHELL AND RELATED ELEMENTS REINFORCED CONCRETE AND SHOTCRETE NOTES PC1. Pool base slab shall be cast-in-place concrete. Pool walls shall be either cast-in-place concrete or shotcrete (wet-mix or dry-mix). PC2. All concrete and shotcrete shall be 4000 psi minimum 28 day compressive strength with 6% air entrainment. Limit water to cementitious material ratio (w/c) to 0.42. PC3. All reinforcing steel shall be detailed, supplied and placed in accordance with these construction documents and with ACI 318-05, ACI 315-05, and CRSI MSP-1-01. PC4. All reinforcing steel shall be shop fabricated to conform to ASTM A615, Grade 60. PC5. All pool concrete shall be wet-cured using hoses and polyethylene covering. PC6. Reinforcing clearance: 2" Pool walls, surge tank walls 2" Pool bottom slabs, surge tank slabs 3" All surfaces cast or shot against earth PC7. When placing shotcrete against existing soil, overlay soil in contact with shotcrete with minimum 10 mil thick plastic sheeting prior to shooting. PC8. Formwork may be required for shotcrete based on base of wall configurations and wall backfill requirements. Coordinate requirements with pool structural sections and project geotechnical report. PC9. Fully encase all underslab piping in concrete unless noted otherwise. CONSTRUCTION LOAD NOTES CL1. All pool structural elements have not been designed for any construction loading, including, but not limited to scaffolding, shoring, lifts, etc. It is the responsibility of the contractor to verify the pool structural elements are capable of withstanding construction loads without damage to the pool structural elements, or, performance of the in-service pool. WATER-TIGHTNESS TESTING WT1. Water-tightness testing per American Concrete Institute is required. See specifications. POOL FOUNDATION STRUCTURE PF1. All Slabs shall be placed on compacted, free-draining, frost-free drainage course: Drainage Course: Narrowly graded mixture of washed crushed stone, or crushed or uncrushed gravel; ASTM D 448; coarse-aggregate grading Size 57; with 100 percent passing a 1-1/2-inch sieve and 0 to 5 percent passing a No. 8 sieve. All fill shall be compacted to a minimum dry density of 95% of the Modified Proctor maximum dry density (ASTM-D1557), placed in 6" to 8" lifts. Place Mirafi 140N or equivalent between drainage fill and subgrade. See project geotechnical report for further recommendations. Drainage Course Thickness (t): 12" For water depths of 0'-0" to 5'-0" PF2. All pool walls shall be backfilled with compacted, free-draining, frost-free drainage fill: Drainage Fill: Narrowly graded mixture of washed crushed stone, or crushed or uncrushed gravel; ASTM D 448; coarse-aggregate grading Size 57; with 100 percent passing a 1-1/2-inch sieve and 0 to 5 percent passing a No. 8 sieve. All fill shall be compacted to a minimum dry density of 95% of the Modified Proctor maximum dry density (ASTM-D1557), placed in 6" to 8" lifts. Place Mirafi 140N or equivalent between drainage fill and subgrade. See project geotechnical report for further recommendations. PF3. See project geotechnical for soil and groundwater conditions. Soil parameters listed below have been used for design of the pool structure. Design assumes removal of soft soils and former building elements per the geotechnical report. During construction, report any discrepancies in soil conditions to the Engineer of Record immediately. Geotechincal report by: Alt & Witzig Engineering, Inc., dated March 1, 2019.
