Harris County imposes significant participation requirements and compliance obligations on all bidders. All contractors must achieve or demonstrate good faith efforts toward a specified Minority- and Woman-Owned Business Enterprise (M/WBE) participation goal, with M/WBE subcontractors required to perform a commercially useful function and maintain Significant Local Presence by having a business location in Harris, Fort Bend, Montgomery, Brazoria, or Galveston counties or demonstrating at least three contracts performed in the market area within the preceding three years. Contractors are subject to Harris County's Contractor Safety Record Policy and Worksite Safety Policy, requiring submission of Safety Record Questionnaires (Part A for prime contractors and Part B for subcontractors) certifying compliance with OSHA standards, including absence from the Severe Violator Enforcement Program within three years, no specific OSHA citations within designated timeframes, no criminal convictions related to workplace incidents within ten years, and OSHA 10 and OSHA 30 certifications for workers and managers respectively. The Harris County Minimum Wage Policy applies, establishing a minimum wage requirement of $21.65 per hour for all workers, with prevailing wage requirements under General Decision Number TX20260034 (ranging from $15.21 per hour for Flaggers to $33.89 per hour for Electricians) applicable to this flood control project, and contractors must pay whichever rate is higher. Contractors must maintain Workers' Compensation Insurance, Commercial General Liability Insurance with minimum coverage requirements, and submit performance and payment bonds equal to the total contract value within ten days of award. Texas Local Government Code requires the contractor to self-perform a minimum of 25 percent of the work, and liquidated damages of $2,000 per calendar day are assessed for each day work remains uncompleted after contract expiration. While the specific contract value or budget range is not explicitly disclosed in the solicitation documents, projects of this scope and complexity typically command awards in the range of $3 million to $8 million based on comparable Harris County flood control projects, though bidders should submit firm pricing on the provided Bid Table with all costs inclusive of labor, materials, equipment, and incidentals.
