Market Research Request for Information (RFI) Ready-Mix Concrete Availability on the Island of Kaua`i The Government is requesting information for local on-island sources of ready-mix concrete to support proposed projects being planned for construction in M?n?, Kaua`i, Hawai`i. The proposed projects will require several mass concrete placements of compressive strengths between 50-100 psi (CLSM) to 6000 psi. Please respond to the questions below: For Established Ready-Mix Concrete Sources: Is your ready-mix concrete batch plant certified by the National Ready-Mix Concrete Association? Will your company be able to provide concrete from your plant to PMRF at 10 yards per truck delivered at 10 minutes intervals for 8 to 10-hour workdays to meet the volumes that may be required for certain placements anticipated for the proposed projects? If not, please specify the maximum number of truck deliveries per hour that can be provided for 8 to 10-hour workdays? Does your aggregate source meet the requirements specified in ASTM C33 / C33M Standard Specification for Concrete Aggregates? Is your aggregate quality capable to achieve concrete compressive strengths of 6000 psi or greater? If so, please provide the concrete mix designs and ASTM C39 / C39M test method results to validate your concrete mixes can achieve 6000 psi compressive strength at 28 days. If not, please provide the mix designs and test results for the strongest mix design you will be able to achieve. For Sources with Mobile Batch Plants: How much area (in acres) would you need to stand up a ready-mix batch plant to meet the various concrete strength requirements as specified in the description above? The areas at minimum should include the batch plant, cement storage silos, and aggregate stockpiles. Please specify how you intend to import the aggregate and cement required to meet questions 1 through 4 for established ready-mix concrete batch plants? This is a RFI and is not to be construed as a commitment by the Government, nor will the Government pay for the information submitted in response. It is emphasized that this RFI is for planning and information purposes only. NO PROPOSALS are being requested nor accepted under this notice. The U.S. Army Corps of Engineers, Hawaii District will use information obtained under this notice to develop an acquisition strategy to help meet the needs for this procurement. Please send your responses to Tammy Davis at tammy.davis@usace.army.mil no later than 7 December 2021.
