About this opportunity
The U.S. Army Corps of Engineers Engineer Research and Development Center is soliciting proposals for a Blanket Purchase Agreement (BPA) Master for Biological Services, seeking a full-service laboratory capable of performing comprehensive biological identification and enumeration services across multiple USACE districts. The contractor will provide analysis services for phytoplankton, zooplankton, benthic macroinvertebrates, cyanotoxins, and chlorophyll samples, including specialized toxin testing for anatoxin, saxitoxin, cylindrospermopsin, and microcystins using ELISA and standard taxonomic identification methods. Key requirements include providing collection bottles, preservatives, and instructions to districts, maintaining sample storage for up to one year post-analysis, and delivering electronic data reports in specified formats. The contract will be evaluated using a lowest-price technically acceptable basis, with proposals assessed on technical capability, past performance, and price. The proposal submission deadline has been extended to September 16, 2025, at 1:00 PM CST, with offerors required to submit three-volume proposals including technical, past performance, and price components.
This opportunity is set aside for small business competition under NAICS code 541380 (Testing Laboratories and Services), with no incumbent contractors identified in the solicitation documents. The contract establishes a five-year ordering period from September 30, 2025, to September 29, 2030, covering biological sampling services for eight USACE districts including Kansas City, Louisville, Chicago, Pittsburgh, Nashville, Omaha, Tulsa, and Vicksburg. Annual sample volumes are estimated at 650-1,000 phytoplankton samples, 250 benthic macroinvertebrate samples, 250 zooplankton samples, up to 200 toxin samples, and 125 chlorophyll samples, with most sampling occurring during March through October. The primary place of performance is Vicksburg, MS, though services will support districts nationwide. Turnaround times vary from 3 to 120 calendar days depending on the specific analysis type, and the government intends to make multiple awards under this BPA structure.
