3 1.00 TERMS SPECIFICATION FOR JOINT UTILITY TRENCH AND EXCAVATION The terms "City, Owner, or Engineer as used herein and on the Drawings shall be considered synonymous and refer to the City of Healdsburg and its duly authorized employees, consultants and/or agents. The terms "Contractor and Bidder used in this Specification shall be considered synonymous and refers to the corporation, company, partnership, firm, or individual who has entered into a Contract for the performance of the Work specified herein DEFINITIONS Contract: The written agreement between the City and the Contractor covering the Work. Day(s): The term Day(s) shall mean consecutive calendar day(s) unless otherwise specified. Work: That which is proposed to be constructed or done under the Contract, including the furnishing of all labor, material, and equipment for performing trenching, excavation, and associated Work. Electric Department Representative: Any staff member of the City of Healdsburg Electric Department that has knowledge of the Work proposed or in progress. Electric Engineer: The City of Healdsburg Electric Department staff member directly involved in the engineering, design, or management of the Work to be performed. Project Manager: The City of Healdsburg staff directly assigned the job of inspecting newly installed underground facilities. Standard Trench Width: Trench widths of 12", 18", and 24" continuing in 6" increments. Utility / Utilities: any investor owned or publicly owned utility within the right of way or participating in the joint trench GENERAL The following specifications are for performing trenching, excavation, and associated work suitable for constructing duct banks and installing boxes and vaults used in the City of Healdsburg as used by it s Electric Department, AT&T, Comcast, and related underground utility work. This bid shall be for Joint Utility Trenching, excavation, and other associated work listed on the Bid Proposal form. The prices bid shall remain constant throughout the course of the work.

4 The terms trenching and excavation means to; trench, excavate, including all required native or select backfill (sand and base rock), concrete replacement, saw cutting, City-approved compaction, slurry mix, concrete caps, barrier posts, placement of required conduit, sidewalks, retaining walls, traffic control, flagging, customer notification, vegetation or brush removal/replacement, temporary and permanent pavement as required and the removal of spoils to complete any trench, excavation, or facility installation. It also includes any and all decorative rock or bark, grass or shrubs, planter including shrubs required to put the construction site back to a condition equal or better than it was prior to when the Work started. The Contractor will coordinate the Work to the maximum extent practical with the affected property owners. Contractor cooperation with property owners affected by the Work is essential. In all instances, the successful Bidder (Contractor) shall be responsible for a complete workable duct bank or box/vault installation suitable for installation of City of Healdsburg power cable and equipment or the communication cable(s) and equipment of AT&T and Comcast as designated by the design STANDARDS Trenching, excavations, substructure installation, and associated work will be on a per unit cost basis utilizing the prices from the Bid Proposal form completed by the Contractor. For the purposes of this specification standard trench widths will be 12", 18", and 24" continuing in 6" increments and based upon the bidded items and joint trench drawings. Dimensions used to calculate total cost of a trench or excavation job will be the lowest standard trench width that will accommodate the minimum required width for the facilities being installed as determined solely by the City of Healdsburg Electric Department (HED) or as required by the City of Healdsburg Construction Standards. As an example, the minimum required trench width for a single 4" conduit would be the nominal size plus 6" for a total of 10. A standard trench width of 12" will accommodate the 10" so the excavation would be priced based on the 12" width. If the minimum trench width required by HED was 20", HED would price the job based on a 24" excavation. Shored trenches will utilize this same methodology with the exception that the minimum standard trench width utilized will be 24" to accommodate the shoring and allow adequate working space within the deeper trench. For ease of pricing payment, cubic yards of box/vault excavation will be based on the box/vault outside dimensions (includes cover) plus 6" for depth and 24" for length and 24" for width [i.e., (L+24")x(W+24")x(D+6") = cubic feet of excavation]. The Contractor is cautioned that the Contractor's unit bid prices will be the only prices utilized in determining the cost of any conduit bank/trench or box/vault excavation price. Items not listed on the bid list but found in the field will be priced using a larger listed bid item as close to the actual item being worked on (i.e., 5" sidewalk will be priced as a 6" sidewalk). Prior to construction of non-bided items, the contractor must gain written approval for the type and quantity of work as directed by a Healdsburg Electric Representative.

5 All Work shall be performed in accordance with the latest City of Healdsburg, AT&T, and Comcast Construction Standard(s) for each of the unit items bid. Only the more significant Standards are listed but contractors must be aware and knowledgeable of all applicable utility standards. Failure to list a Standard will not be grounds for a change order or failure to perform the Work in accordance with all applicable Construction Standards. It is expected that the Bidder will be fully aware of the current Construction Standards related and applicable to the work. The Bidder should review these drawings/standards prior to submitting their bid. a.) Trenching Remove existing soil and materials at the location of the trench to the depth, width, and length required and install all required substructures. All trenching with adequate depth in streets, sidewalks, and driveways on public and private property shall be backfilled, above the sand bedding/cover, with an aggregate base material (base rock) and compacted to City specifications. Trenches in all other areas may be backfilled with native soil (unless directed otherwise by an Electric Department Representative) over the sand base/cover per utility standards. Compaction shall be a minimum of 95% in areas of vehicular traffic and a minimum of 90% in all other areas. City of Healdsburg (or its agent) may periodically perform compaction tests on various trench sections to determine if the minimum compaction requirements have been met. If a trench section fails to meet the minimum compaction requirement, the Contractor, at his expense, shall re-compact the trench section by removing and replacing all backfill material within the failed trench section and pay for all retesting to prove the trench section meets the minimum compaction requirement. In areas of trench or excavation (principally in unpaved/proposed traffic areas) where the Contractor has asked for and received approval to use slurry mix (approved by the Electric Department and Public Works Department) to satisfy the compaction requirement of the Construction Standards or where the Public Works Department requires slurry mix as an alternative way of meeting the compaction requirement of the City, there will be no additional adder for slurry mix to the trench or excavation cost. Where the Joint Trench requires trenches over 60" deep, the cost of trenching shall include shoring costs. The Contractor shall remove all spoils from the job site and repair landscaping, street, sidewalks, etc. to their original preconstruction condition or better. Trench bid prices shall include backfilling with required sand bedding, or select material, and native soils. Trench bid prices shall include the labor and material costs required for a complete trench package, slurry as required at bends, costs to clean (brush) and mandrel conduits installations, and install 1250lb. or 2500lb. mule tape or equivalent pull line as required per utility construction standards and drawings (as applicable) and California Public Utilities Commission General Order 128 (GO-128). b.) Box and Vault Excavation (Including Switch Vaults)

6 Remove existing materials at the location of the excavation to the depth, width and length required. Place substructure in excavation per City of Healdsburg and applicable Utility Standards and Field Direction. Backfill and compact per Utility, as required for compaction. It will be the Contractor's responsibility to contact the box/vault vendor to verify outside dimensions of substructures to assure the excavation is the correct size for the substructure being delivered. For box/vaults, the City's vendor will deliver the box/vault to the Contractor's completed excavation and set the box/vault in the Contractor's excavated pit. It is the Contractor's sole responsibility to schedule the box/vault deliveries from the box/vault manufacturer (vendor) and to provide the box/vault manufacturer the correct City of Healdsburg purchase order number for the box/vault(s) to be delivered. City of Healdsburg purchase order numbers for box/vaults are obtained through the Electric Department Representative assigned to the Work. It shall be the Contractor's responsibility to accept or decline the delivery of all vaults, boxes, and equipment pads to ensure they are acceptable to the City of Healdsburg and participating Utilities. If the Contractor accepts a vault, box, or equipment pad that does not meet the City's or any participating Utility s requirements, the Contractor will be responsible for all costs to remove and replace the vault, box, or equipment pad. Any questions regarding the acceptability of a vault, box, or equipment pad shall be referred to the City of Healdsburg Representative or other representative. If upon delivery, a vault, box, or equipment pad does not meet the Inspection Criteria, the Contractor shall immediately notify the HED. The Representative will then direct the Contractor on how to proceed and will coordinate the repair or replacement of the structure. Full compensation for inspecting the vault for compliance with the listed criteria shall be included in the contract bid price for the vault, box, or equipment pad and no separate payment will be made for inspection. In all cases, the Contractor shall be responsible for a complete box, pad, vault, or switch vault installation.

The unit prices in the Bid Proposal, including surface repair and backfill, will be used to determine the total cost of the trench. The total cost of the trench will be appropriately divided between all parties (Utilities) of the joint trench, per the City of Healdsburg. Box/vault excavations and conduit placements will not be considered part of the joint trench. Other Utilities in the joint trench will inspect their own conduits, excavations and vault/boxes. If the Contractor enters into an agreement for box/vault installation, excavations and/or conduit work for other Utilities, the Contractor must negotiate and collect his own fee with those other Utilities. If the Contractor allows unauthorized utilization of the joint trench by others, the total

15 cost of the trench will be divided equally by the numbers of unauthorized participants in the trench and the Contractor will be paid only the City of Healdsburg s portion of the trench WORK LIMITATIONS The Contractor will not be required to perform any boring or trenching, excavation, and associated work to cross a major-divided freeway such as Highway 101 unless mutually agreeable CONTRACT WORK The successful Bidder awarded the Contract will, perform the work and be paid based upon specific quantities of trench, excavation and/or associated work at the unit prices quoted in the Contractor's bid.
