ELEV: 862.12 N: 1721725.13 E: 192848.76 AQUA-SWIRLTM PCS SPECIFICATION NOTES 10-23-15 1. Manufacturer shall be responsible for complete assembly of watertight Swirl Concentrator. 2. Polymer Coated Steel (PCS) Swirl Concentrator shall be fabricated from polymer pre -coated steel sheet for corrugated steel pipe, and shall comply with ASTM A 760 and ASTM A 742. 3. Stub outs and internal components shall be supplied by manufacturer and MIS welded using accepted welding practices. 4. Manufacturer shall supply direct access to Swid Concentrator via 30-inch ID riser(s). If necessary to accommodate field adjustments, Contractor may cut Riser to match finish grade. The exposed metal of the cut riser must be recoated using the touch up kit supplied with each PCS unit. If necessary to extend deer, Contractor should use adjusting rings to bring top of structure to grade. 5. Contractor shall supply pipe couplings to and ham Swirl Concentrator, which shall be Mar -Mac, Femco, or Mission style flexible boot with stainless steel tension bands and shear guard. 6. Contractor shall prepare excavation and off- load Swid Concentrator. Contractor is responsible for bedding and backfill around Swirl Concentrator as detailed on site plan (see notes 11 and 12). Any exposed metal (scratches or other damage to the polymer coating) must be recoated using the touch up kit supplied with each PCS unit prior to installation or placement of bacld'III. 7. Manufacturer shall supply standard manhole fiame(s) and cover(s) (Traffic rated HS-25). 8. Where traffic loading (HS-25) is required or anticipated, a 4-foot diameter, tall thick reinforced concrete pad must be placed over the Swirl Concentrator to support and level the manhole frame. The top of riser pipe must be wrapped with compressible expansion joint material to a minimum 1-inch thickness to allow transfer of wheel leads from manhole cover to concrete slab. Manhole cover shall bear on concrete slab and not on riser pipe. The concrete slab shall have a minimum strength of 3,000 psi and be reinforced with #4 reinforcing steel (per drawing). Minimum cover over reinforcing steel shall be 1-inch. Top of manhole cover and concrete slab shall be level with finish grade. 9. Unless other traffic bartiers are present, bollards shall be placed around access risers in non -traffic areas to prevent inadvertent loading by maintenance vehicles. Sample of typical bollard installation detail and recommended locations of bollards around the Swid Concentrator can be provided upon request. 10. Where high groundwater elevations are present a anticipated, Contractor shall supply concrete anti -Floatation pad underneath and poured over the octagonal base plate of the swirl (see Anti -Floatation Base Detail) to prevent buoyancy and base plate deflection (details, if necessary, available upon request). 11. Excavation and Bedding - The trench and trench bottom shall be constructed In accordance with ASTM A 798 Section 5, Trench Excavation, Section 6, Foundation, and Section 7, Bedding. The PCS Swid Concentrator shall be installed on a stable base consisting of at least 6-inches of fine, readily compacted soil or granular fill material, and compacted to 95% proctor density. Bedding shall not contain stones retained on a 3-inch ring, frozen lumps, highly plastic clay, organic material, corrosive material, or other deleterious foreign materials. All required safety precautions for Swid Concentrator installation are the responsibility of the Contractor and shall be per OSHA approved methods. 12. BackfIll Requirements - Backfill materials shall be fine, readily compacted soil or granular fill material, and compacted to 90% proctor density. Processed granular materials with excellent structural characteristics are preferred. Coarse grained soils of USCS Groups GW, GP, GM, GC, SW, and SP as described in ASTM D 2487 are generally acceptable materials when compacted to 90% proctor density. Backfill shall not contain stones retained on a 3-inch ring, frozen lumps, highly plastic clay, organic material, corrosive material, or other deleterious foreign materials. Backfilling shall conform to ASTM A 798, Section 10, Structural Backfill Placement. Backfill shall be placed in 6 to 12 inch layers or "lifts" and compacted before adding the need lift. Backnll shall extend at least 18 inches outward from Swid Concentrator and for the full height of the Swid Concentrator (including riser(s)) extending laterally to undisturbed soils.
