- Description
- Description: The U.S. Army Corps of Engineers (USACE) New England District will host an Industry Day for the Environmental Remediation Dredging of tidal flats and an outfall drainage channel in the Housatonic River adjacent to the Stratford Army Engine Plant (SAEP), Stratford, Connecticut project.�The NAICS code for the work described below is 562910 (750 employees).� NAE plans to award this project using a Design/Bid/Build model.� The construction is expected to take 18 months� The estimated construction cost is between $50,000,000.00 and $60,000,000.00.� This is a set-aside for Small Business and�will be a Best Value Procurment. The purpose of this Industry Day is to provide contractors and subcontractors information on SAEP, USACE�s solicitation process and requirements and provide answers to questions.� The event will be held virtually on January 26, 2021 from 10:00 a.m. to 4:00 p.m.� WebEx Link: https://usace1.webex.com/meet/erika.l.mark Dial-In Number: +1-844-800-2712 Access code: �199 928 3668 # Included with this Industry Day notice are the DRAFT Design Documents for SAEP.� These draft design documents are not final.� Contractors are responsible for checking the final documents when the solicitation is released.� �� We ask that you submit project-related questions NLT 20 January 2021, 3:00 p.m. EST via email to Heather.Skorik@usace.army.mil.� USACE staff will provide responses, as appropriate, to questions during Industry Day. Overview of Stratford Army Engine Plant, Stratford, CT: The selected contractor will need to meet precise dredge target elevations. Dredging, placement of material into scows, dewatering, water treatment/discharge, transfer of material into trucks, and depositing of material onsite must be performed with minimal spillage or turbidity. Measures will be required to minimize the spread of contaminated sediments and contain turbidity. Deployment of a bottom seal silt curtain will be required. Dredging is generally limited to depths below mudline of 1 to 4 ft, ranging in tidal water depths of 2 ft [high tide] to approximately 10 ft. Dredged material must be segregated into three categories for purposes of disposal/reuse characterization based upon PCB concentration (=1 to = 50 mg/kg). Materials containing less than 1 mg/kg PCBs are suitable for on- site re-use. Materials containing greater than 1 mg/kg PCBs must be disposed of off-site at facilities licensed to accept these materials. All in-water work must be completed within an 18-month continuous allowable work window. Dredging accuracy will be key to minimizing the amount of over-dredging while still attaining the target cleanup goals of the project. The tidal flats dredging shall be performed using precision mechanical dredging methods. Sediments shall be dredged using a sealed environmental level cut bucket to limit the generation of resuspended sediments and overdredge required to meet project objectives. State-of-the-art monitoring and positioning systems are required to ensure the allowable overdredge can be achieved. Turbidity measurements and comparison to project-specific standards (to be determined) will be required up- and downstream of the active work area. The dredging shall be performed in a careful, well-designed manner so that downstream project-generated turbidity is kept to a minimum, and when appropriate, actions may be required to reduce turbidity generation to maintain compliance. The dredged sediment shall be dewatered and Portland cement added for purposes of onsite stockpiling and future reuse on the site. Excavation of the Outfall 008 drainage channel shall be performed �in the dry� by dewatering the channel and diverting storm and tidal flows. The drainage channel will require backfilling and restoration. The tidal flats shall be backfilled to within one foot of original grade using a sandy material. The contactor shall procure the sand material from an offsite upland source. Saltmarsh restoration and establishment period monitoring, will be required for resource areas impacted by dredging operations under this contract.
