§ 99.16 CONSTRUCTION METHODS AND MATERIALS.
   (A)   All construction methods and materials shall be in conformance with Chapter 100 and the City of Danville construction standards, the conditions of the project permit, applicable State and Federal laws and codes, industry standard practices and the following:
      (1)   Boring or jacking.
         (a)   Pits and shoring. Boring or jacking under rights-of-way shall be accomplished from pits as located in the approved plans. Pits for boring or jacking shall be excavated no more than 48 hours in advance of boring or jacking operations and backfilled within 48 hours after boring or jacking operations are completed. While pits are open, they shall be clearly marked and protected by barricades. Shoring shall be designed, erected, supported, braced, and maintained so that it will safely support all vertical and lateral loads that may be imposed upon it during the boring or jacking operation.
         (b)   Wet boring or jetting. Wet boring or jetting shall not be permitted under the roadway.
         (c)   Borings with diameters greater than six inches. Borings over six inches (0.15 m) in diameter shall be accomplished with an auger and following pipe, and the diameter of the auger shall not exceed the outside diameter of the following pipe by more than one inch (25 mm).
         (d)   Borings with diameters six inches or less. Borings of six inches or less in diameter may be accomplished by either jacking, guided with auger, or auger and following pipe method.
         (e)   Tree preservation. Any facility located within the drip line of any tree shall be bored under or around the root system.
      (2)   Trenching. Trenching for facility installation, repair, or maintenance on rights-of-way shall be done in accord with the applicable portions of IDOT Standard Specifications for Road and Bridge Construction.
         (a)   Length. The length of open trench shall be kept to the practicable minimum consistent with requirements for pipe-line testing. Only one-half of any intersection may have an open trench at any time unless special permission is obtained from the City Engineer.
         (b)   Open trench and excavated material. Open trench and windrowed excavated material shall be protected as required by the approved erosion control plan and State and Federal laws. Where practicable, the excavated material shall be deposited between the roadway and the trench as added protection. Excavated material shall not be allowed to remain on the paved portion of the roadway. Where right-of-way width does not allow for windrowing excavated material off the paved portion of the roadway, excavated material shall be hauled to an off-road location.
         (c)   Drip line of trees. The utility shall not trench within the drip line of any tree.
      (3)   Backfilling.
         (a)   Any pit, trench, or excavation created during the installation of facilities shall be backfilled for its full width, depth, and length using methods and materials in accordance with the IDOT's “Standard Specifications for Road and Bridge Construction” and Chapter 100.
         (b)   For a period of 2 years from the date construction of a facility is completed, the utility shall be responsible to remove and restore any backfilled area that has settled due to construction of the facility. If so ordered by the Engineer, the utility, at its expense, shall remove any pavement and backfill material to the top of the installed facility, place new backfill material, and restore new pavement, sidewalk, curbs, and driveways to the proper grades, as determined by the Engineer within 45 days of being notified to do so. If at the end of 45 days the work has not been completed, the City may perform the work and be reimbursed according to § 99.10.
      (4)   Pavement cuts. Pavement cuts for facility installation or repair shall be permitted on a highway only if that portion of the highway is closed to traffic and the requirements of § 99.10 and Chapter 100 are met. If a variance to the limitation set forth in this division (4) is permitted under § 99.21, the following requirements shall apply:
         (a)   Permit Required. A permit for pavement cuts shall be obtained according to § 99.10 or § 100.40 as applicable.
   (B)   Any excavation under pavements shall be backfilled according to Chapter 100 or as designated by the Engineer.
   (C)   Restoration of pavement shall be accomplished as soon as practicable, according to Chapter 100. Pavement restorations shall be required to remain in at least as good condition as the surrounding pavement until such time that the entire pavement is replaced or rehabilitated. If so ordered by the Engineer, the utility, at its expense, shall remove and replace pavement restorations within 45 days of being notified to do so by the Engineer. If at the end of 45 days the work has not been completed, the City may perform the work and be reimbursed according to §§ 99.10, 100.99 or Chapter 166 as applicable.
   (D)   Temporary restorations. While awaiting permanent restorations, repairs in any improved highway or alley shall be temporarily patched with a minimum of 8 inches of CA-6 granular material and a minimum of 2 inches of bituminous asphalt material. Temporary patches shall be made within 24 hours of backfilling unless otherwise approved by the City Engineer. The material shall be compacted in place and maintained until a permanent restoration is installed. Temporary repairs shall be maintained by the utility and repaired within 24 hours notification by the City after which time the City may elect to maintain the repair and seek reimbursement according to § 99.10. Permanent restorations shall take place within 30 calendar days unless otherwise approved by the City Engineer.
   (E)   Use of steel plates. Steel plates covering an excavation within a highway shall be installed only with the permission of the City Engineer. Steel plates shall be secured with bituminous asphalt ramps a minimum of 6 inches in width. Steel plates shall be removed within 7 calendar days and the pavement opening temporarily or permanently restored unless otherwise approved by the City Engineer. The City of Danville Department of Public Works shall be notified upon the installation of steel plates and shall be notified of their removal.
   (F)   All saw cuts shall be full depth.iv) For all rights-of-way which have been reconstructed with a concrete surface/base in the last 7 years, or resurfaced in the last 3 years, permits shall not be issued unless such work is determined to be an emergency repair or other work considered necessary and unforeseen before the time of the reconstruction or unless a pavement cut is necessary for a J.U.L.I.E. locate.
   (G)   Opening to traffic. Highways shall not be reopened to traffic until the density and or strength requirements of Chapter 100 are met.
   (H)   Encasement shall be required for facilities under a highway.
      (1)   Casing pipe shall be designed to withstand the load of the highway and any other superimposed loads. The casing shall be continuous either by one-piece fabrication or by welding or jointed installation approved by the City.
      (2)   The venting, if any, of any encasement shall extend within one foot (0.3 m) of the right-of-way line. No above-ground
vent pipes shall be located in the area established as clear zone for that particular section of the highway.
      (3)   In the case of water main or service crossing, encasement shall be furnished between bore pits unless continuous pipe or City approved jointed pipe is used under the roadway.
      (4)   In the case of gas pipelines of 60 psig or less, encasement may be eliminated.
      (5)   In the case of gas pipelines or petroleum products pipelines with installations of more than 60 psig, encasement may be eliminated only if:
         (a)   Extra heavy pipe is used that precludes future maintenance or repair and
         (b)   Cathodic protection of the pipe is provided;
      (6)   If encasement is eliminated for a gas or petroleum products pipeline, the facility shall be located so as to provide that construction does not disrupt the right-of-way.
   (I)   Minimum cover of underground facilities. Cover shall be provided and maintained at least in the amount specified in the following table for minimum cover for the type of facility:
 
TYPE OF FACILITY
MINIMUM COVER
Electric Lines Communication, Cable or Video Service Lines
