Call 1 04-3AA504

This contract, identified by solicitation number 04-3AA504 and titled “Call 1 04-3AA504,” is issued by the California Department of Transportation (Caltrans) for construction services primarily focused on environmental compliance, hazardous material handling, and infrastructure installation within Marin County, California. The work encompasses soldier pile wall installation, sculpted shotcrete application, galvanized staining of concrete surfaces, and the removal and disposal of treated wood waste and culverts, with a total estimated contract value of $4,470,000, including a 5% contingency. The contract is structured primarily as fixed-price lump sum arrangements with no option quantities or extension clauses indicated. Key performance requirements include strict adherence to California Environmental Quality Act (CEQA) standards, compliance with the California Health and Safety Code §25230 et seq. for hazardous waste, and implementation of specific environmental protection measures such as daily wildlife surveys, work stoppages upon detection of protected species, and restrictions during nesting season and storm events. All treated wood waste must be stored under controlled conditions—up to 90 days uncovered or one year under permanent cover—with labels containing seven mandatory elements, including Caltrans district and contract numbers, contractor information, and compliance statements. Contractors must be pre-registered as plan holders with Caltrans and use the DIME portal for submittals of environmental declarations and documentation, with additional reports directed to specific water board email addresses. Inspections occur at both the job site and approved disposal facilities, with acceptance contingent on meeting stringent quality benchmarks for concrete, including ASTM testing protocols and Certified Concrete Field-Testing Technicians. Materials must comply with Buy America requirements under 2 CFR 184.6, particularly when costs exceed threshold amounts for small businesses or Disabled Veteran Business Enterprises, triggering detailed supply chain documentation. Personnel requirements are rigorous, mandating the presence of a Qualified Biologist on-site throughout active work hours, 24/7 coverage of a Temporary Signal System Coordinator, and mandatory training certification for all workers on species protection protocols. Payment processing is conducted exclusively through Caltrans’s dbestystem portal, and no traditional FAR clauses or federal contracting identifiers such as AAC, TAS, or CAGE codes are used, reflecting the state-level regulatory framework. There is no defined performance period, but time-sensitive activities like hydroseeding and erosion control are tied to seasonal windows between September and February.
