GRADING GRADE IS DEFINED AS THE BOTTOM OF THE CLASS 5 AGGREGATE BASE. 2. SUITABLE GRADING MATERIAL ON THIS PROJECT SHALL CONSIST OF ALL SOILS ENCOUNTERED WITH THE EXCEPTION OF TOPSOIL, DEBRIS, PEAT, MUCK, OTHER ORGANIC MATERIALS, OR OTHER UNSTABLE MATERIAL. 3. UNSUITABLE GRADING MATERIALS ARE TOPSOIL, DEBRIS, PEAT, MUCK, ORGANIC MATERIALS, OR OTHER UNSTABLE MATERIAL. 4. GRANULAR MATERIAL SHALL MEET THE REQUIREMENTS OF MN/DOT SPEC. 3149.281. 5. STRIP ALL TOPSOIL AND INPLACE SLOPE DRESSING WHERE PRESENT IN AREAS TO BE DISTURBED BY CONSTRUCTION AND REUSE SLOPE DRESSING. SLOPE DRESSING ON THIS PROJECT IS DEFINED AS THE TOPSOIL OR OTHER SOILS WHICH HAVE BEEN PLACED DURING PREVIOUS CONSTRUCTION TO PROVIDE A MEDIUM FOR ESTABLISHING TURF. THE AVERAGE DEPTH OF TOPSOIL LAYER IS ASSUMED TO BE 6 INCHES. 6. ALL TURF REMOVAL AND TOPSOIL STRIPPING LIMITS IN PREPARATION OF PLANTINGS AND RESTORATION SHALL BE CONSIDERED INCIDENTAL TO THE COMMON EXCAVATION. 7. DISPOSITION OF EXCESS EXCAVATED MATERIAL SHALL BE IN ACCORDANCE WITH MN/DOT SPEC.2105.3D WITH NO DIRECT COMPENSATION MADE THEREFORE. 8. OBTAIN COMPACTION ON THE GRADING AND AGGREGATE BASE PORTIONS OF THE CONSTRUCTION IN ACCORDANCE WITH THE "SPECIFIED DENSITY METHOD" REQUIREMENTS. 9. TEST ROLLING PALL BE REQUIRED ON THIS PROJECT IN ACCORDANCE WITH MNDOT SPEC. 2211 (INCIDENTAL). 10. STABILIZING AGGREGATE SHALL BE INCORPORATED INTO THE SUBGRADE TO ACHIEVE SATISFACTORY SURFACE STABILITY AT LOCATIONS DEEMED NECESSARY BY THE ENGINEER, IN ACCORDANCE WITH THE PROVISIONS OF MNDOT SPEC. 2105.3G. GRANULAR MATERIAL WHICH IS FURNISHED BY THE CONTRACTOR SHALL BE STABILIZED, IF NECESSARY, AT THE CONTRACTORS EXPENSE. 11. UNLESS OTHERWISE SPECIFICALLY ALLOWED OR REQUIRED BY THE CONTRACT, BITUMINOUS AND CONCRETE ITEMS DISTURBED BY CONSTRUCTION SHALL BECOME THE PROPERTY OF THE CONTRACTOR AND SHALL BE RECYCLED TO THE EXTENT ALLOWED IN BASE AND SURFACING ITEMS OR DISPOSED OF OUTSIDE THE RIGHT-OF-WAY IN ACCORDANCE WITH SPEC. 2104.3C3. 12. UNLESS OTHERWISE REQUIRED, ADD 1(V) TO 20(H) TAPERS TO THE FULL DEPTH STATION LIMITS OF ALL SUB GRADE EXCAVATIONS. PROVIDE 1(V) TO 20(H) TRANSITION TAPERS BETWEEN CHANGES IN SUB GRADE EXCAVATION DEPTH LONGITUDINALLY. 13. THE TOP OF BACKSLOPES AND THE TOE OF FILL SLOPES SHALL BE ROUNDED. 14. THE LOCATIONS OF THE EXISTING UTILITIES SHOWN ON THE PLANS ARE APPROXIMATE. THE CONTRACTOR SHALL VERIFY UTILITY LOCATIONS AND DEPTHS AS REQUIRED BEFORE EXCAVATION. EXCAVATIONS TO LOCATE UTILITIES SHALL BE INCIDENTAL. THE CONTRACTOR SHALL BE RESPONSIBLE TO COORDINATE PATH THE UTILITY COMPANIES AND CALL THE "GOPHER STATE ONE CALL" (1-800-252-1166) AT LEAST 48 HOURS PRIOR TO EXCAVATION/CONSTRUCTION. 15. ANY DEBRIS WHICH MAY BE ENCOUNTERED DURING GRADING SHALL BE DISPOSED OF BY THE CONTRACTOR OFF THE PROJECT RIGHT-OF-WAY IN A SUITABLE DISPOSAL AREA AS APPROVED BY THE ENGINEER. 16. BITUMINOUS REMOVAL QUANTITY BASED ON SQUARE UNIT REMOVED REGARDLESS OF PAVEMENT DEPTH. CONTRACTOR SHALL INVESTIGATE AND MAKE OWN DETERMINATION OF ACTUAL PAVEMENT DEPTH. 17. PIPE SEWERS CONNECTING MANHOLES AND CATCH BASINS SHALL BE IN ACCORDANCE WITH SPEC. 2503. BEDDING AND BACKFILL SHALL CONSIST OF UNIFORM SELECTED GRADING MATERIAL MATCHING ADJACENT SOILS UNLESS OTHERWISE DIRECTED BY THE ENGINEER. 18. WHENEVER THE WORD 'INCIDENTAL" IS USED IN THIS PLAN, IT WILL MEAN THIS WORK WILL BE INCIDENTAL FOR WHICH NO DIRECT COMPENSATION WILL BE MADE. 19. PLACE MINIMUM 6 IN. TOPSOIL OR SLOPE DRESSING ON ALL AREAS DISTURBED BY CONSTRUCTION AND SCHEDULED FOR PERMANENT TURF ESTABLISHMENT. TOPSOIL BORROW TO BE UTILIZED AT THE DIRECTION OF THE ENGINEER IN THE FIELD. 20. ALL EROSION CONTROL MEASURES SHOWN IN THE PLANS SHALL BE IN PLACE PRIOR TO THE COMMENCEMENT OF GRADING OPERATIONS. .� EWATER A WATER 1- DEEP SAW JOINT CONDUIT CONDUIT OR PIAN -CONCRETE DISTRIBUTION SLAB 4 OF 44 SI N
