Site work for a water / sewer project in Minneapolis, Minnesota. Completed plans call for site work for a water / sewer project.

The Metropolitan Council (Council) is soliciting Prequalification Submittal Documents (PSD's) for the purpose of establishing a list of prequalified SPECIALTY CONTRACTORs to provide the specialty construction associated with compaction grouting beneath the existing interceptor, instrument monitoring during the grouting application, liner removal, rehabilitation of existing sanitary interceptor, installation of a new M228A metering structure and incidental restoration work. The purpose of this Invitation for Prequalification (IFP) is to develop a list of SPECIALTY CONTRACTORs with previous experience in the successful performance of similar work from which to request bids. SPECIALTY CONTRACTORS may be the CONTRACTOR (also generally known as General CONTRACTOR and/or Prime CONTRACTOR) or a Subcontractor to the CONTRACTOR, but they will be prequalified independently of their relationship to any CONTRACTOR and must prepare an independent submittal to be prequalified. The prequalification for compaction grouting, instrumentation monitoring and CIPP liner removal will be used to create a list of prequalified specialty contractors that will be allowed to perform the work. SPECIALTY CONTRACTORs PSDs may be submitted for any or all of the following specialties: 1. Compaction Grouting 2. Instrumentation Monitoring 3. CIPP Liner Removal The IFP Administrator for this Invitation for Prequalification is: Name: Kimberley Ruedy E-mail: Kimberley.Ruedy@metc.state.mn.us All questions regarding this IFP are to be directed only to the IFP Administrator. October 6, 2025. Only written requests will be accepted. Major scope of the construction work includes: Mobilization, traffic control, erosion control, utility locates and potholing, construction of temporary shafts (two), construction of permanent shafts (one), construction of manholes, temporary conveyance of wastewater, bulkheads, cleaning of sanitary sewer interceptors, cured-in-place pipe (CIPP), removal of existing CIPP liner, low mobility grouting, instrumentation, pipe grouting and restoration. Approximately 278 feet of 36" CIPP lined RCP pipe has settled and in need of rehabilitation. The existing interceptor is approximately 25 to 30 feet below grade with elevated groundwater conditions.The proposed work consists of raising the interceptor up to 18 inches using low mobility grouting. In addition, the existing CIPP liner will be removed and replaced, and a new M228A Meter Station will be constructed. The project contains three components requiring specialized expertise and experience: The prequalified Specialty Contractor for Compaction Grouting will furnish engineering design, labor, equipment, and material to complete work via compaction grouting measures to densify soils and reestablish the original line and grade of the 36" CIPP lined RCP pipe using compaction grouting.
