Tasks 1-12 and B apply to the entire Landfill.

We anticipate a leachate collector in lift 1 and horizontals in lift 2 designed and installed under a separate contract. In Section 5.0 on Page B-5, the RFP indicates that Detailed Design and CQA of north-south leachate collector for Lift 1 and Horizontal Collectors for Lift 2 are not in scope for project; however, then it requests technical memorandums for Schedule and Cost Estimate, 50% Design, 95% Detailed Design and Project Wrap Up Report.
