Sanborn Head will prepare the required opinions of cost using the required NHDES forms
based on the permitted closure plan, currently available average unit costs for similar
projects, current costs for monitoring services, published construction cost estimating
guides, and our engineering judgment. We will estimate the remaining life of Phases I and
II based on the latest survey update, and prepare sinking fund calculations using account
balances provided to us, actual waste tonnage received at the Landfill, and the projected
waste tonnage for the remaining estimated life of Phases I and II. The calculations will
demonstrate that the balances for the closure and LTMM accounts are consistent with what
was projected or provide amounts per ton that should be set aside going forward to
provide sufficient funds at the expected date of closure.
Sanborn Head will prepare a letter addressed to the City that documents our evaluation,
which will include NHDES Cost Estimate Forms for landfill closure and post-closure care,
and sinking fund calculations.
Task5 GCCS Related Services
Sanborn Head submitted a proposal to the City on April 21, 2016 for “Additional GCCS
Related Services” as requested by the City. Subsequently, a purchase order was issued by
the City for this work on July 13, 2016 (P.O. #127711). The scope of work under that
agreement included the following:
= Preparation of an assessment of the Phases I and II Gas Collection & Control System
(GCCS);
= Preparation of a conceptual design for a vertical landfill gas (LFG) well dewatering
system;
= Preparation of construction documents for the next GCCS expansion in Phase II, Stage II;
and
= Providing bid and construction phase services for the GCCS expansion in Phase II, Stage
Il.
As stated above, these services will be provided under a separate purchase order (P.O.
#127711). Notwithstanding the separate GCCS project, this time and expense task will
allow Sanborn Head to assist the City with GCCS related matters in FY 2017.
Task6 General Engineering Services
Sanborn Head’s services under this task will be performed at the City’s request and involve
routine matters of limited scope, such as attending meetings with regulators and providing
design, operation, or air consultation relative the Landfill.
