AI Contract Overview

The City of San Buenaventura is soliciting proposals for construction management services related to the Santa Paula Branch Line – Rails With Trails Project, identified by solicitation number 20260730023 and posted on August 2, 2026, with a response deadline of August 31, 2026. The project is located in Ventura, California, with a zip code of 93001, and is governed under the NAICS code 541330 for engineering services. The primary point of contact is Alejandro Puga, reachable via email at [email hidden] or phone at [phone hidden]. While the solicitation indicates a bid number of 2024-D-041 and references a contract value of $19, no financial or pricing data, CLINs, or cost breakdowns are present in the supporting documentation, rendering the actual contract value unverifiable. The technical scope of work centers on geotechnical evaluation, including soil borings, laboratory testing, and foundation design recommendations for slab and raised floor systems, with specific requirements for soil treatment such as overexcavation to a minimum depth of 21 inches, 90% relative compaction per ASTM D1557, and pre-moistening of expansive soils to 120%–130% of optimum moisture content. Reinforcement standards mandate the use of No. 4 bars at mid-depth of slabs with continuous doweling across joints, along with installation of a 6-mil polyethylene vapor barrier and perimeter drainage where expansive soils are encountered. Inspection and acceptance activities are tied to field operations at key locations such as Harmon Barranca, Sudden Barranca, and Bristol Road, with compliance verified using established standards including ASTM D6938 and D1556 for compaction testing, ASTM D4718 for R-value corrections, ACI 318-14 for sulfate exposure, and the 2022 California Building Code Appendix J for grading. The Unified Soil Classification System is used to classify subsurface materials with design parameters derived from laboratory results such as moisture content, dry density, plasticity index, and R-values ranging between 25 and 38.8. Although geotechnical data from boreholes is extensive, including drilling dates, soil classifications (CL, ML
