Site work for a water / sewer project in Bristol, Vermont. Design plans call for site work for a water / sewer project.

Per the owner, as of February 10, 2022, a company has been selected for this solicitation. The owner states that a timeline for construction has not been determined. Closed solicitation has been included below for reference. .................. Request for Proposals for consultant services to produce final designs of two stormwater management projects. These two projects (School St. 001 and School 1 & 2) are located near the Bristol Memorial Park and Bristol Elementary School Respectively, and are identified in the Town's Stormwater Master Plan. The purpose of these projects is to reduce or eliminate stormwater runoff that feeds into an outfall to the New Haven River. A system of sub-surface chambers is envisioned for the School St 001 site. These chambers would sit under the road and parking spaces adjacent to the park. This structure would be flush with the ground, essentially invisible other than a manhole structure for operation and maintenance access. WCA proposed to use ADS StormTech MC-4500 chambers at this location to maximize storage and infiltration potential. Three rows of chambers would be laid out so the total number of chambers equals 68 for a total storage volume of 12,466 cubic feet. This asymmetric configuration was chosen to minimize disturbance to the park and its associated features such as trees, play structures, and gardens. A system of sub-surface chambers is envisioned for the School 1 & 2 sites. These chambers would sit under the playgrounds behind the school. This structure would be flush with the ground, essentially invisible other than structures foroperation and maintenance access. WCA proposed to use ADS StormTech MC-4500 chambers at this location to maximize storage and infiltration potential. One row of approximately 11 chambers and another row of approximately 12 chambers would be laid out for sites 1 & 2 respectively. The combined storage potential will total 4,556 cubic feet. Both of these systems may require additional drainage infrastructure (catch basins and pipes) to adequately convey runoff to them. The system for School 1 would also be able to treat runoff from the large area above Mountain Street. This could alleviate some strain on the existing drainage infrastructure along that road. Additional infrastructure will be installed to ensure that not all runoff from the large drainage area above Mountain Street is routed to a singular chamber system on the School property, which could result in more nuisance flooding or groundwater mounding. The successful consultant will work with the Town of Bristol and the ACRPC to produce final engineering designs and bid documents for both the School St 001 and School 1&2 project. Proposed designs should significantly reduce or eliminate stormwater runofffrom these areas to the New Haven River. Questions and should be e-mailed by 4:00pm, Friday, April 30, 2021 to: Maddison Shropshire, Water Quality Planner ECO AmeriCorps Member Addison County Regional Planning Commission mshropshire@acrpc.org Scope of Work The successful consultant will work with the Town of Bristol and the ACRPC to produce final engineering designs and bid documents for both the School St 001 and School 1&2 project. Proposed designs should significantly reduce or eliminate stormwater runofffrom these areas to the New Haven River. The following outline identifies tasks and deliverables: Task 1: Kickoff meeting. Task 2: Check in with the DEC Regional River Scientist and obtain review of the 30% design before proceeding with the final designs. Check-ins must include submittal of project concepts/plans to date and discussion of project objectives and potential constraints. Task 3: Add projects to the Agency of Natural Resources project locator map (http://anrmaps.vermont.gov/websites/anra5/). Task 4: Supplemental site surveys and subsurface soil investigations. Task 5: Refine the hydraulic analysis as needed.Task 6: 60% plans and details. Task 6a: Check in with the DEC Regional River Scientist and obtain review of the 60% design before proceeding with the final designs. Check-ins must include submittal of project concepts/plans to date and discussion of project objectives and potential constraints. Task 7: Public meeting and presentation with the Selectboard Task 8: 100% final design plan and details, including a synthesis of the prior completed deliverables, final cost estimates, and level of effort. Must follow the 2017 stormwater manual for technical aspects andguidance for design and provide treatment of the water quality volume (1inch, 24-hour storm) or, if that is not possible due to site constraints, maximize treatment of runoff to the extent practicable. Task 9: Final performance report following a template developed by either DEC or SWRPC Task 10: Documentation of required permits. Contact DEC Stormwater Program to identify and obtain applicable operational or construction stormwater permits or obtain determination no permits are required. Indicate potential challenges or conflicts for obtaining the permit(s), if applicable.T ask 11: Documentation of operation and maintenance plans and responsible party(ies) once the project is implemented. Task 12: Specifications for construction bid documents. The method of contractor selection has not been determined at this time. 4/30/2021 Deadline for submission of questions 05/07/2021 Response to questions posted 05/24/2021 Bristol Selectboard meeting 05/26/2021 Consultant selection notification June 2021 Project kick-off September 2021 Project completion
