SCOPE OF WORK The general location of the project is within the Silver Creek stream channel beginning on the Mt. Hope High School campus continuing upstream to approximately 136 feet northwest of the cul- de-sac of Leila Jean Drive and approximately 1,000 feet north of the intersection of Leila Jean Drive and Chestnut Street. The work addressed by this contract includes but is not limited to, creating and erecting two signs that identify the RIDEM application number for the project; mobilization; preparation of staging and access areas; coordination with the Town on the removal of steel storage containers (Conex-type boxes) from high school staging area; limited vegetation pruning along channel banks and for machinery access; installation, re-installation, and removal of turbidity curtain( per plan); installation and removal of compost filter sock; installation and removal of temporary construction mats as conditions may warrant; removal of logs and other obstructions from river channel; removal and lawful disposal of accumulated sediment from river channel; handling, stockpiling, transporting, and lawfully disposing of any removed sediment determined by Beta Group to be contaminated; and installation of a stone check dam in existing stormwater swale/basin. The Work also includes loaming and seeding lawn areas and restoring driveways disturbed by construction activities; site cleaning; demobilization; and all incidentals required to complete the work of this contract to the satisfaction of the Town of Bristol. The Town has obtained landowner authorization and will notify all landowners of the selected Bidder and scheduled date of mobilization. Work will occur in residential yards and on the High School property, so limits of disturbance and access routes must be strictly adhered to. All sediment removed from the river channel shall be temporarily stockpiled on the grounds of the Town of Bristol’s Transfer Station at the terminus of Minturn Farm Road, in coordination with the Director of the Department of Public Works, for proper de-watering, prior to transport and disposal at a licensed disposal facility. Three temporary stockpile areas near Silver Creek have been designated on the contract drawings as optional, interim locations for transferring sediment to lined dump trucks for hauling to the Transfer Station. The contractor is responsible for all transporting of sediments, from the river channel to interim stockpile areas, to the Transfer Station, and to the licensed disposal facility. Sediments will be waterlogged, or at least saturated, so the method of transport must be watertight to prevent liquids from leaving truck beds during transport operations. Copies of all weight slips from the licensed disposal facility must be furnished to the Town of Bristol. A RI Department of Environmental Management (RIDEM) Freshwater Wetlands Insignificant Alteration Permit (RIDEM No. 19-0259) dated July 15, 2020, has been obtained for this project. Additionally, a Short Term Response Action Plan dated December 11, 2019, has been prepared specific to the project and RIDEM issued a Short-Term Response Action Approval Letter (RIDEM No. SR-02-1941) on March 24, 2020. Copies of these three (3) documents have been made part of this RFP, and all work MUST conform to the requirements and conditions of each of these documents.
