The contract includes rigorous safety and regulatory requirements, including compliance with California wage determinations and federal minimum wage executive orders. Environmental and health protocols are a primary focus, with specific mandates for managing lead-based paint identified on exterior window sills and fascia, as well as strict adherence to the Hantavirus Risk Reduction Program to protect workers from rodent-borne illness. The selection process utilizes a Best Value Trade-Off evaluation, requiring offerors to provide detailed past performance questionnaires, project experience, and financial references. Multiple amendments were issued to clarify technical specifications for materials, update wage rates, and extend proposal deadlines.
