Bidders must provide a base bid for the installation of a 60 mil Tremply KEE Single-Ply Membrane and an alternate bid for a multi-ply Modified Bitumen Roofing System. Additionally, the contractor must implement a maintenance program featuring yearly visual inspections and a 24-hour leak reporting response service. The selection process is based on the lowest and best bid, evaluating bidder qualifications, financial ability, and technical compliance. Mandatory submission requirements include a signed Confidentiality and Business Relationship/Non-Collusion Representation and insurance certificates on ACORD 25 or 25S forms.
