(A) All excavations made under permit, within the street lines, provided for in §§ 97.01 to 97.10, inclusive, shall be backfilled with bank-run gravel as approved by the Director of Public Works. All excavations shall be backfilled and compacted or suitably covered to the satisfaction of the Director of Public Works or his designee at the end of each workday, unless suitable alternatives have been previously approved by the Director of Public Works or his designee. The contractor shall be responsible for the cost of repairs due to settlement or use of improper backfill material. Improper backfill shall be re-excavated and temporarily patched in accordance with the provisions of this subchapter. In the event of the failure of a temporary patch, the contractor will be notified and will repair the same within 24 hours of notification. Upon failure to comply with this provision or for emergency situations when the public is at risk, the Director of Public Works or his designee may direct the repair to be done and will bill the contractor. The contractor shall be liable for the full expense of such work, with such expense to be paid within 45 days of billing. Delinquent payments will be charged against the performance bond.
(B) Material removed from the excavations may be used for backfill upon written permission of the Director of Public Works or his designee. In all cases when the material used for backfill is that which was excavated from the trench, the backfilling must be done in properly compacted layers of two feet for the entire depth of the trench. All muck, clay, frozen earth or other deleterious material shall be replaced with bank-run gravel. When bank-run gravel is used for backfilling, all materials removed from the excavation shall be removed from the site and properly disposed of by the contractor. All ditches within the travelway of any street or highway shall be sealed immediately by the contractor with a suitable patching material approved by the Department of Public Works.
(C) For utility companies or those companies that have a full permanent paving schedule as determined by the Town Engineer, the trench shall be placed in kind as a minimum. The trench shall be properly backfilled and sealed with a temporary patch for a period not to exceed 180 days. Pavement shall be restored to conform to Section 4.01 "Bituminous Concrete" of Form 814A - State of Connecticut, Department of Transportation, Standard Specifications for Roads, Bridges and Incidental Construction, as may be amended from time to time. For those streets or roadways having a concrete base or surface, the trench shall be temporarily backfilled as specified above. The backfill shall be brought to a level to allow for the replacement of the concrete to the thickness of the original contract or as directed by the Director of Public Works or the State of Connecticut, as applicable.
(D) Concrete placed in any trench shall be allowed to cure for not less than 72 hours. During the curing period, all excavations shall be properly protected by barricades and warning lights furnished and maintained by the contractor. If the concrete is a base material, the top surface shall be of bituminous concrete or other paving material approved by the Department of Public Works, with a minimum compacted thickness of three inches, properly joined and sealed to the existing pavement. The sides of all excavations and patches shall be cut in a straight line where joined to the old pavement. If the concrete is the finished paving material, the concrete shall be screened and rubbed to the satisfaction of the Director of Public Works.
(E) In case of any question, Section 4.01 "Concrete Pavement" of Form 814A - State of Connecticut, Department of Transportation, Standard Specifications for Roads, Bridges and Incidental Construction, as may be amended from time to time, may govern.
