Site work for a water / sewer project in Balsam Lake, Wisconsin. Completed plans call for site work for a water / sewer project.

The Village reserves the right to refuse any and all bids. Question Deadline 10/16/2023 Issuing Point of Contact David Patterson, Director of Public Works 404 Main Street PO BOX 506, Balsam Lake WI 54810 715-485-3424 dpw@lakeland.ws & vobl@lakeland.ws Starting at 507 West Main Street by Our lady of the Lake Catholic Church east to the intersection of West Main Street & Perl Street Scope of work The Village of Balsam Lake is seeking bids for rehabilitation of pipelines and conduits by the installation of a resin-impregnate flexible tube via a process commonly referred to as Cured-InPlace-Pipe (CIPP) trenchless technology. This tube shall be inverted into the original pipeline/conduit and expanded to fit tightly against said pipeline by the use of water or air pressure. The resin system shall then be cured by elevating the temperature of the water or aur used for the inflation to a level of sufficient for the initiators in the resin to effect a thermosetting reaction. Pre-Cleaning and Inspection - The Contractor shall clean the pipes or conduits to be lined thoroughly before commencement of the CIPP process. Root masses, debris, protruding laterals, mineral or other attached deposits, or any other matter not herein defined, shall be removed from the conduit at this time. A complete closed-circuit television (CCTV) inspection of each line segment shall be included in this process to document the condition of the pipe or conduit post cleaning but prior to CIPP lining. Cured-In-Place- Pipe Lining - The Contractor shall rehabilitate the pipe segments identified by the Owner in accordance with ASTM F1216 Rehabilitation of Existing Pipelines and Conduits by Inversion and Curing of a Resin-Impregnated Tube. This process shall conform to all requirements for liner thickness, cure time, inversion method(s), testing, quality control, and other methods and process as may be specified herein. Liner pipe thickness design shall be in accordance with Appendix XI of ASTM F1216. The existing pipe shall not be considered as providing any structural support to the liner pipe (Fully Deteriorated Case). In the liner thickness calculations, the following specifications shall apply: The minimum ovality of the host pipe shall be two percent (2%) The height of ground water shall be a minimum fifty percent (50%) of the pipe depth The enhancement factor (K) shall be no greater than seven point zero (7.0) The minimum safety factor shall be two point zero (2.0) Date of Issuance: September 19th, 2023 Issued by: Village of Balsam Lake, Department of Public Works Due Date for Proposals: October 16th 2023 The flexural modulus of elasticity shall be reduced 50% to account for long term effects and used in the design equation EL. All final thickness shall be considered as finished thickness (post curing). Bypass Pumping - Contractor shall provide such piping, pumping, connections, fittings, and other appurtenances as necessary to bypass flows. There shall be no disruption of flow to the existing lines caused by the installation of this bypass, nor shall any sewer spills or overages be caused as a result of this action. Reinstatement of Laterals and Connections - This work includes the reinstatement of all laterals and other connections that may be temporarily blocked as a result of the CIPP process. The Contractor shall use a mechanical cutter or other means as approved by the Engineer to place these connections back in service as soon as practicable after the curing process is complete. Post Installation Inspection and Documentation - After the installation and curing of the CIPP liner, and after the reinstatement of laterals or other connections, the Contractor shall perform a CCTV inspection to document the condition of the rehabilitated pipes and laterals (if any). Traffic Control - The Contractor shall be solely responsible for all signage, flagging, cones, personnel and any other item or personnel required for traffic control. Locating Manholes and Access Points - It shall be the responsibility of the Owner to locate, designate, and otherwise provide all manhole or access points for the work, and to provide to the Contractor rights of access to these points. Access to Water - The Owner shall provide free access to and usage of water hydrants for cleaning, installation of the tube, and other work items requiring water. Debris Removal Prior to CIPP Installation - The Contractor shall remove all internal debris from the pipeline that will interfere with the installation of the CIPP. The Owner shall provide at its expense a dumpsite for debris removed during the cleaning operations. Unless stated otherwise, it is assumed that this site will be at or near the local sewage treatment facility. Any hazardous waste encountered during this project will be considered as a change of conditions. Necessary Point Repairs - If pre-installation inspection reveals an obstruction that will prevent the CIPP installation process, and this obstruction cannot be removed by conventional sewer cleaning or cutting equipment, the Contractor shall make a point repair excavation to uncover and remove or repair the obstruction. Such excavation shall be approved in writing by the Owner's representative prior to the commencement of the work and shall be considered as a separate pay item.
