Scope of Work CONCEPT CHK: The work required under this section includes all concrete and bituminous paving and related items necessary to com- plete the work indicated on Plans and described in the Specifications, including but not limited to: All streets, parking areas in Contract limits Curbs and Gutters of Highway Standard Specifications (IDHSS), latest revision, and the town of Morristown Utility and Infrastructure Construction Standards, latest revision. 3. Grading: Perform any necessary grading to that accomplished in accordance with SECTION V, GRADING -to bring all sub grades, after final compaction, to the required grades and cross sections for site improvement. 4. Preparation of Subgrade: Contractor shall perform all top soil stripping operations for street areas pursuant to SECTION VII, STRIPPING, and shall perform proof rolling and earthwork construction operations pursuant to SECTION V, GRADING and to the requirements stated in section 207 of IDHSS, per latest revision. 5. Compaction of Subgrade: All roadway areas (including the areas beneath the curbs), regardless of whether they are located in Cut or Fill, shall have the first six (6) inches below the final subgrade elevation compacted to at least 100/ of the maximum dry density as determined by the provi- sions of AASHTO T -99. Water shall be prevented from stand- ing on the compacted subgrade. 6. Acceptance of Subgrade: The Earthwork Contractor shall coordinate the preparation of subgrade with the town of Morristown, the Owner, and thPaving Contractor. Subgrade shall be inspected and tested by the town's. authorized inspector prior to pavement construction. The condition of the subgrade as finally and acceptably prepared shall prevail at the time any paving material is placed thereon. Prepared subgrade damaged for any reason prior to acceptance by the town of Westfield and Paving Contractor shall be repaired by the Earthwork Contractor at no additional cost to Owner. Approved subgrade shall be paved with the initial H.A.C. base course one day after acceptance by the Street Inspector. Approved subgrade damaged for any reason after acceptance by the owner, town and the Paving Contractor shall be repaired by the Paving Contractor at no additional cost to Owner. ENG CHK: J.B.G. Should the Paving Contractor refuse acceptance of the sub- grade, he shall notify the Earthwork Contractor and the Owner of the deficiencies. Should the Paving Contractor fail to notify the Earthwork Contractor and the Owner of any deficiencies and /or proceed in the placing of the H.A.C. base course, said actions shall constitute acceptance of subgrade. The Owner shall have the authority to adjust the construc- tion schedules of the Earthwork Contractor and the Paving Contractor as is required to meet the above requirements. DRAWN BY: G.S.W. DRFTNG. CHK: G.S.W. SCALE: N/A DATE: 10 -10 -02 7. Utility Structures: Earthwork Contractor shall check for correct elevation of all manhole covers, valve boxes and similar structures located within areas to be paved, and make, or have made, any necessary adjustments in structures. Paving Contractor shall verify the above prior to placing pavement materials. Adjustments to utility structures required after placement of paving materials shall be the responsibility of Paving Contractor. 8. Bituminous Pavement: All materials and construction methods proposed for the construction of bituminous pavements shall comply with section 403 of IDHSS, per latest revision. The front face of curbs shall be tack coated where H.A.0 pave- ment will be in contact. Unless specific approval is grant- ed, paving will not be permitted during unfavorable weather or when the temperature is 40 degrees F. and falling. 9. Tack and Prime Coats: If the previously constructed course is granular and a prime coat is required, priming shall conform with applicable provisions of section 408 of IDHSS, per latest revision. The tack coat on H.A.0 base or binder shall conform with requirements set out in section 409 of IDHSS, per latest revision. 10. Compacted Aggregate Base Course: shall conform with material and construction method requirements set out in section 303 of (DHSS, per latest revision. The thickness shown on the Plans is the minimum thickness of the fully compacted aggre- gate base course. Compaction shall be accomplished by rolling with a smooth wheeled roller weighing 8 to 10 tons. Compact to 100 X of maximum dry density in accordance with IDHSS section 304.05, latest revision. Along curbs, head- ers, and walls and at all places not accessible to the roller, the aggregate material shall be tamped with mechani- cal tampers or with approved hand tampers. 11. Pavements built by stage construction, that is pavements used to carry traffic before the full pavement structure is complete, shall have the temporary stage fully inspected by the town of Morristown for distressed areas before the next stage is started. Distressed areas will be repaired to the satisfaction of the Town before an additional stage is constructed. 12.
