About this opportunity
The South Dakota Department of Transportation (SDDOT) is seeking research proposals for a project focused on evaluating the performance of non-Vinsol Resin Air Entraining Concrete Admixtures (AEAs). The procurement is a research contract aimed at identifying alternative AEA products that can be used in SDDOT concrete mixes, following the closure of the sole Vinsol Resin manufacturing facility. Key objectives include conducting a comprehensive literature review, interviewing state DOTs and admixture companies, and developing a testing matrix to evaluate synthetic AEA performance. The research will aim to demonstrate the compatibility of new AEA products with existing concrete materials and potentially update SDDOT specifications to allow broader AEA usage. Proposals must be submitted electronically as PDF documents to andy.vandel@state.sd.us and michael.border@state.sd.us by 5:00 pm CDT on March 20, 2024. The evaluation criteria will include the proposer's understanding of the problem, feasibility of the research plan, quality of deliverables, implementation strategy, staffing capabilities, and overall budget alignment. The technical panel will assess proposals based on their comprehensive approach to addressing the AEA supply and performance challenges.
The solicitation does not explicitly mention specific set-aside designations or restrictions on respondent types. The project appears open to qualified research institutions, universities, or consulting firms with expertise in concrete admixture technology and materials testing. The proposed project has a budget of $200,000 and is scheduled for an 18-month duration, with a potential start date of July 1, 2024. SDDOT will provide necessary concrete materials for testing and expects the successful proposer to present findings to the Research Review Board. No incumbent vendors are specifically identified, though the research aims to expand the current list of approved AEA products beyond the Vinsol Resin-based options. The project represents a critical effort to ensure a reliable supply of compatible concrete admixtures for future SDDOT infrastructure projects, addressing potential supply chain disruptions caused by the closure of the Vinsol Resin manufacturing facility.
Opportunity text
Problem Description: Current specifications only allow Vinsol Resin-based Air Entraining Admixtures (AEA) in concrete mixes used on SDDOT projects, and the use of synthetic AEAs is not allowed. This restriction reduces the number of AEA products available for use on SDDOT projects, which could potentially delay projects if supply issues develop related to the production of Vinsol Resin-based AEAs.
The South Dakota Department of Transportation (SDDOT) previously completed research project SD98-03 which determined that synthetic AEA products were the source of the concrete strength issues experienced by the Department at that time. As a result of this research, SDDOT discontinued the use of synthetic AEAs and removed all synthetic AEAs from the Department's approved products list, thus effectively prohibiting them from use on SDDOT projects.
In the last 20+ years, the technology of synthetic AEAs has improved and AASHTO has developed a recommendation for evaluating AEAs (NCHRP Report 578). Research demonstrating the acceptable performance of synthetic AEAs would expand the supply of products allowable for use on SDDOT projects. This research would give SDDOT guidance on which synthetic AEAs produce acceptable results and could be added to the department's approved products list and provide changes to the current specifications to include non-Vinsol resin AEAs.
On April 15, 2023, the sole manufacturing facility for Vinsol Resin experienced an industrial fire which put the facility out of production. In June 2023, the owner of the facility, Pinova Inc., announced plans to decommission the facility and permanently end operations. As a result of this fire and subsequent closure, it is expected that Vinsol Resin-based AEAs will become increasingly difficult to acquire until all existing Vinsol Resin-based AEAs currently in the market have been exhausted. Ultimately, having additional AEA products available for use by SDDOT will be necessary to ensure that the AEA products used on SDDOT projects are compatible with the other materials used in SDDOT concretes.
Proposal Deadline: Proposals are due to the SDDOT by 5:00 pm CDT on Wednesday, March 20, 2024. This deadline is firm. Extensions will not be granted.
Proposals must be submitted as an e-mail attachment in Portable Document Format (PDF) not exceeding 14MB. The email must be addressed to andy.vandel@state.sd.us and michael.border@state.sd.us. Proposers should send the e-mail using "Delivery Receipt" and "Read Receipt" options to verify successful delivery.
Proposal Guidelines: Proposals must fulfill the requirements listed in the document entitled RESEARCH PROPOSAL PREPARATION, SUBMISSION, AND EVALUATION and dated October 28, 2022.
Proposal Evaluation: Proposals will be evaluated by a technical panel knowledgeable in the problem area. Selection will be made in consideration of criteria listed in RESEARCH PROPOSAL PREPARATION, SUBMISSION, AND EVALUATION.
Project Management: Michael Border is responsible for the management of this project and can be reached at michael.border@state.sd.us to answer inquiries.
