ize standard for this NAICS Code is 541620 for Environmental Consulting Services. The small business size standard for this NAICS is $19 million, and the Project Service Code is B510 for Specials Studies/Analysis - Environmental Assessments. The Period of Performance is anticipated to be May 01, 2027 through April 30, 2030. PROJECT DESCRIPTION: The U.S. Army Corps of Engineers (USACE), San Francisco District is the primary user of the San Francisco Deep Ocean Disposal Site (SF-DODS), located 50 miles offshore of the Golden Gate. As such, USACE is frequently required to conduct benthic sampling in accordance with the site monitoring plan. Box cores and sediment vertical profile imaging are collected to assess the sites chemical, physical and biological condition. Chemistry samples are taken from the box cores and the top 10 centimeters are sieved and the biota are preserved for future taxonomic assessment. Due to frequent inclement conditions at the site, a larger (over 150 ft) vessel is required to perform operations safely. Physical, chemical and biological data will be analyzed and presented in a detailed report. The Contractor shall provide all personnel, tools, materials, vehicles, supervision, and other items and services necessary to conduct the benthic surveys. This includes supplying a suitable vessel (over 150 ft) to work from that includes a crew, marine technician and a cook. The vessel must have a galley, lab and sleeping space for the sampling team, an ample work deck, appropriate winches and cabling for deep water sampling and appropriate electronics to track a 12 megahertz pinger. The contractor will supply an 8-man crew which will be accompanied by 2 scientists from the USACE and USEPA respectively. Operations will be conducted around the clock, weather permitting, with two shifts of 5 scientists. It is imperative that the team has documented experience in sampling at depths over 2500 meters and the types of troubleshooting that are usually necessary to maximize success in achieving sampling goals. Specific experience in the use and troubleshooting the Sandia MK-III 0.25 meter box corer broken into 25 10 cm x 10 cm sub-cores is very important. In addition, the contractor will need to provide this type of box corer, which will take some effort to locate. The sampling cruise for the base year is proposed to occur in September / October 2027.
