AutoCAD SHX Text GENERAL NOTES: : FIELD VERIFY MH ELEVATIONS, AS WELL AS SUMP PUMP, MANHOLE LIDS, AND VENT PIPE LOCATIONS. SUBMIT MANHOLE LAYOUT, FOR GOVERNMENT APPROVAL, PRIOR TO ORDERING. COORDINATE ELEVATION OF MANHOLE TO ALLOW SIDEWALK TO BE REPLACED TO MATCH EXISTING SURROUNDING CONCRETE SIDEWALK. TOP OF MH CANNOT BE USED AS SIDEWALK SURFACE. MANHOLE SHALL BE DESIGNED TO SUPPORT LARGE EQUIPMENT, SUMP PUMP & COMPONENTS SHOWN ON THIS DRAWING FOR REFERENCE ONLY. THE CONTRACTOR WILL BE REMOVING EXISTING SUMP PUMP SYSTEM, AND REINSTALLING IN NEW MH. PERFORMANCE TESTING WILL BE REQUIRED AFTER. ELEVATIONS OF HTHW PIPE ENTRY & EXIT MAY VARY FROM DRAWINGS. REFERENCE SHEET M17.4 FOR INITIAL ELEVATIONS. DIFFERENT TYPES OF SUPPORTS MAY BE PRESENT IN AREAS WHERE THE COFFINS ARE BEING REMOVED/SHORTENED. THEY ARE NOT SHOWN FOR CLARITY IN THESE SECTION DETAIL REFERENCES. FOR BIDDING PURPOSES, ASSUME ANCHORED SUPPORTS ARE INSIDE COFFIN, EACH SIDE OF THE MANHOLE. SEE DETAILS THIS SHEET.. EXISTING MANHOLES WERE PLACED ON CONCRETE FOUNDATION BLOCKS. FOR BIDDING, ASSUME 2' THICK 10' X 10' ACROSS. PAST INSTALLATION ALSO HAD 10' x 10', " INCH THICK METAL PLATE, MOUNTED ON TUBING SUPPORTS EMBEDDED INTO THE THRUST BLOCK. CONTRACTOR MUST INCLUDE 38" INCH THICK METAL PLATE, MOUNTED ON TUBING SUPPORTS EMBEDDED INTO THE THRUST BLOCK. CONTRACTOR MUST INCLUDE DEMOLISHING THESE FOUNDATION BLOCKS AND STEEL SUPPORTS/PLATES TO ALLOW NEW MANHOLE INSTALLATION. MH - ABBREVIATION FOR MANHOLE.
