(b) The waste disposal cell shall accommodate two (2) years of waste disposal capacity in Area B. Based on an assumed large cell footprint, the design shall consider a phased-use of the cell (e.g. internal sacrificial berms) to manage leachate generation. (c) Quality Assurance for the HDPE liner shall include leak location testing; the Consultant shall ensure that the design and construction methodology support leak location testing for the entire HDPE liner system. The Consultant should also consider potential efficiencies towards the proposed construction contract administration resident services under D5.1.7(c). (d) Prepare an excavation plan to minimize double handing of soils during construction (e.g. excavated material may be used to construct berms and access road subgrade). (e) A Class 1 cost estimate is required at least six (6) weeks prior to issuing the tender for construction. (f) Develop tender documents using City’s construction contract template. The City will post the tender documents on MERX.
