No oral interpretations shall be made to any respondent as to the meaning of any proposal document. The Town of Simsbury (hereafter referred to as "the Town") is seeking qualified Contractors that have both a skilled workforce and appropriate equipment to provide trenchless culvert restoration services including cure in place pipe (CIPP), slip lining, epoxy coating, geopolymer, etc. for two locations in Simsbury, CT: 1) Lucy Brook crossing near 137 East Weatogue Street, Simsbury, CT 06070 (hereto referred to as "Lucy Brook") and 2) the alternate proposal for the Munnisunk Brook crossing near 81 County Road, Simsbury, CT 06070 (here to referred to as "Munnisunk Brook"). The current condition of the Lucy Brook culvert is outlined in Appendix A. The current condition of the Munnisunk Brook culvert is outlined in Appendix B.

Proposals can include the use of any restoration method that the contractor believes provides the best solution at each location. The Town will evaluate al proposals based on method, life span, firm or company experience, and total cost This guidance document assumes that a decision has been made by CT DOT to rehabilitate a culvert using a structural liner. Nonstructural liners will be allowed as a temporary method to stabilize an existing culvert quickly to provide time to initiate a project to address the proper rehabilitation or replacement of the culvert. A nonstructural liner may also be used in combination with a structural liner to achieve a smoother interior surface. Selecting a structural liner to rehabilitate a culvert is complicated. Selection requires consideration of many stakeholders. It is important to set some goals that the culvert liner must satisfy. These typically include: A. Meets the Purpose and Need established for the project B. Coordinates with other projects in Planning, Design or Construction phases C. Considers the need for culvert extension for roadway widening or to minimize the height of endwalls D. Is structurally adequate (shall be designed by LRFD Design Methodology) E. Is hydraulically adequate (allowable headwater depth, effects of flooding both upstream and downstream, etc.) F. Avoids potential erosion, piping, and scour G. Is durable H. Is capable of providing a 50-year minimum design service life unless the Department authorizes a lesser service life I. Considers the minimum height inside of the lined culvert for inspection access (typically 5') J. Is maintenance free, needs little maintenance, or does not hinder access for maintenance K. Supports habitat/passage for fish and other species where applicable L. Considers the need for a detour or stage construction M. Considers construction access to the inlet and outlet N. Considers geometry of channel and available length at inlet and outlet to set liner in channel before it is pushed or pulled into the host culvert. O. Minimizes environmental impact from construction activities P. Is constructible Q. Considers worker safety for culvert entry and construction techniques R. Considers water handling needs
