THE CONTRACTOR SHALL REMOVE THE EXISTING CONCRETE ANTI -VORTEX DEVICE & RAISE THE 042" CONCRETE RISER RIM ELEV. APPROXIMATELY 3' TO AN ELEV. OF 351 -Se. 2:. THE CONTRACTOR SHALL REMOVE THE EXISTING SOLID & PERFORATED STANDPIPE USED FOR DEWATERING PURPOSES. 3. THE CONTRACTOR SHALL THEN SEAL ALL SIX EXISTING 0i2" MID -FLOW & HIGH-FLOW ORIFICES (INVERT ELEVATIONS OF 339-72'& 344.63')- THE CONTRACTOR SHALL START THIS PROCESS BY REMOVING THE TRASHRACKS & DRYING THE ORIFICE OPENINGS. THE CONTRACTOR SHALL.THEN AFFIX FORMS FOR THESE ORIFICE OPENINGS TO THE RISER. THE FORMS SHALL BE MADE OF FLEXIBLE PLASTIC TO ACCOUNT FOR THE RISER's CURVATURE. AFTER SETTING UP THE FORMS FOR THE ORIFICES, THE CONTRACTOR SHALL FILL THE ORIFICE OPENINGS COMPLETELY WITH CONCRETE, FREE OF VOID SPACES, AND ENSURE THE CONCRETE ADHERES TO THE EXISTING RISER's DRY SURFACES AROUND THE PERIMETERS. AFTER THE INTERIOR CONCRETE IS SET, THE FORMS ARE TO BE REMOVED. NEXT, WHERE THE NEW CONCRETE MEETS THE RISER'S EXISTING INTERIOR AND EXTERIOR CONCRETE SURFACES ALONG THE PERIMETERS, THE CONTRACTOR SHALL 'BUTTER' THESE LOCATIONS WITH NEW CONCRETE. THE CONTRACTOR SHALL ENSURE THIS APPLICATION OVERLAPS THE NEW & OLD CONCRETE SO THAT ANY CRACKS THAT MAY EXIST BETWEEN THE TWO SURFACES ARE SEALED. THIS APPLICATION SHALL BE APPLIED TO THE RISER's INTERIOR AND EXTERIOR RISER/ORFICE INTERFACES ON ALL ORIFICES BEING SEALED. THE CONTRACTOR SHALL ALSO'BUTTEW THE HOLES THAT RESULTED FROM THE REMOVAL OF THE TRASHRACKS. AFTER ALL OF THE SEALED MID -FLOW & HIGH FLOW ORIFICES' CONCRETE HAVE SET, THE CONTRACTOR SHALL ENSURE THE RISER IS WATERTIGHT. 4. THE CONTRACTOR SHALL THEN INSTALL A NEW SOLID SCHEDULE 4o PVC go* ELBOW ATTHE BASE AND CONNECT IT TO THE EXISTING ORIFICE OPENING RECEIVING RUNOFF FROM THE RECENTLY REMOVED DEWATERING APPARATUS. THE CONTRACTOR SHALL THEN INSTALL A VERTICAL SOLID PVC SCHEDULE 4o STANDPIPE BETWEEN THE go° ELBOW AND THE PROPOSED BASIN FLOOR ELEVATION OF 342'. THE CONTRACTOR SHALL THEN REINSTALL THE EXISTING PERFORATED STANDPIPE TO THE SOLID PVC STANDPIPE, PROVIDED IT WAS NOT DAMAGED DURING THE DISASSEMBLY. IF THE EXISTING PERFORATED PIPE WAS DAMAGED DURING ITS REMOVAL, THE CONTRACTOR SHALL INSTALL NEW PERFORATED STANDPIPE & CONNECT ITTO THE SOLID PVC STANDPIPE, WHICH ULTIMATELY DRAINS INTO THE EXISTING LOW -FLOW ORIFICE BEING UTILIZED. THE SOLID PVC STANDPIPE SHALL BE ANCHORED IN STONE MEASURING 22" IN DEPTH AT THE BASE WHERE IT CONNECTS WITH THE RISER AT THE go* ELBOW. ABOVE THE BASIN FLOOR ELEVATION OF 342', THE PERFORATED STANDPIPE SHALL BE AFFIXED TO THE RISER FOR STRUCTURAL STABILITY WITH PLASTIC WRAPS. 5. THE CONTRACTOR SHALL THEN ENCASE THE RISER's BASE IN A REINFORCED CONCRETE FOUNDATION 2' DEEP AND 7'x7' IN AREA. AFTER THIS CONCRETE FOUNDATION SETS, THE CONTRACTOR SHALL THEN BACK FILL THE BASIN's LOWER 6% FURTHER ANCHORING THE RISER & ESTABLISHING A NEW BASIN FLOOR ELEVATION OF 342'. 64 THE CONTRACTOR SHALL THEN INSTALL 3 NEW 03,2" MID -FLOW ORIFICES WITH AN INVERT ELEVATION OF 346.63'. THIS ORIFICE SHALL BE INSTALLED SUCH THAT IT IS STAGGERED IN BETWEEN THE EXISTING HIGH-FLOW ORIFICES'RECENTLY SEALED SO THATTHE STRUCTURAL INTEGRITY OF THE 042" STANDPIPE IS NOT COMPROMISED. STATE APPROVED TRASHRACKS SHALL BE INSTALLED FOR THE NEW ORIFICES NEXT. T. THE CONTRACTOR SHALL INSTALL A NEW RISER TRASHRACK DEVICE AFTER ALL PROPOSED MODIFICATIONS HAVE OCCURRED.
