- Description
- This is a Sources Sought Notice. This Sources Sought neither constitutes a Request for Proposal, nor does it restrict the Government to an ultimate acquisition approach. This Sources Sought should not be construed as a commitment by the Government for any purpose. Requests for a solicitation will not receive a response. This Sources Sought Notice is in support of a market survey being conducted by the St. Louis District, Corps of Engineers to identify interested Contractors within the District area for the Scope of Work listed below. The following are general capabilities required to perform the Scope of Work according to USACE standards. The Contractor must be capable to perform the Scope of Work listed below. General Project Description: The East St. Louis Flood Control Project or Metro East Sanitary District (MESD) levees are generally located along the eastern bank of the Mississippi River, between Edwardsville, Illinois and Cahokia, Illinois. The MESD Stations 973+00 to 1020+00 levee segment along the Mississippi River is the location where the deep cutoff wall is to be constructed. A.) Work Statement: Construction of approximately one continuous section of a deep cutoff wall totaling approximately 4600 linear feet which tie into bedrock, degrade of levee slope and placement of compacted impervious clay fill is needed. B.) MESD Cutoff Wall: The work provided for herein consists of furnishing all plant, labor, equipment, and material, except earth material from required excavations, and performing all operations necessary for construction of a deep soil-cement-bentonite cutoff wall. MESD deep slurry trench will be panel constructed as a continuous soil cement- bentonite cutoff wall approximately 4600 feet long and a minimum of two feet wide. The slurry wall will be tied into limestone bedrock approximately 120 to 140 feet below existing ground. Construction of the cutoff wall will require a temporary work platform approximately 5 - 10 feet thick. Other construction activities will include removal of unsuitable materials from the riverside face of the existing levee and placement of a minimum 5 foot thick clay cap on the riverside levee face. The subsurface conditions typically consist of 1 to 10 feet of clay material underlain by approximately 110 to 130 feet of sands, gravels, and cobbles. Below the sands is bedrock which the cutoff wall will tie into. Borings in the area indicate occasional rough drilling and the presence of occasional buried rubble (glass, wood, metal). The borings do not indicate continuous layers of rough drilling or rubble at the depths of the proposed cutoff wall. There are a variety of utility crossings along the alignment that might affect construction sequencing. The soil-cement-bentonite cutoff wall will be required to meet strict QA/QC requirements. For example, the soil-cement-bentonite must meet a minimum permeability requirement of 1x10-6cm/s, clay cap material must meet USCS classification for CL or CH material, in place clay cap material will need to meet 95 percent of the maximum dry density and plus 4 and minus 0 percent of the optimum water content of a standard proctor test. The cutoff wall will also require detailed as-builts. Lab testing and/or in-situ testing will likely be required to verify compliance with permeability requirements. C.) Capability Statements: 1. Explain your capability/experience to construct a continuous soil-bentonite cutoff wall to approximately 120 to 140 feet below existing ground and maintain the slurry within 2 ft of the ground surface. 2. Briefly explain experience working in varied soil conditions to include but not limited to sand, gravels, zones of cobbles, and zones of boulders. 3. Explain your capability to verify permeability requirements through permeability testing of wet grab samples obtained from various depths. E.) Please provide business information in the following format: Business Name: Point of Contact: (Name/Phone/Email) Address: Business Size (Large/Small/8(A)) Cage Code: F.) Any information submitted by respondents to this Sources Sought Notice is strictly voluntary: The Government will not pay for any information that is submitted by respondents to this Sources Sought Notice. The Government requests interested firms submit one (1) copy of their capability and experience response no later than 2:00 p.m., Central Standard Time, on June 19, 2018 and should not exceed 10 one-sided, 8.5 X 11 inch pages, with the font no smaller than 10 point, to the following address: Contracting Division, Attn: Barrietta Killiebrew, St Louis District, Corps of Engineers, 1222 Spruce Street, St Louis, Missouri, 63103-2833, Fax will not be accepted. Email will be accepted, send to barrietta.killiebrew@usace.army.mil. Please direct any questions on this announcement to Barrietta Killiebrew at the above email or phone number 314-331-8514.
