Re: — Proposal for Construction Quality Assurance Services
Phase IH Construction Project
Four Hills Landfill
Nashua, New Hampshire

Dear Kerry:

Sanborn, Head & Associates, Inc. (Sanborn Head) is pleased to provide the City of Nashua
(City) with this proposal to provide construction quality assurance (CQA) services associated
with the construction of Phase II] (Project) at the Four Hills Landfill in Nashua, New
Hampshire. We understand the Project involves: (i) modifying and improving site drainage
and stormwater treatment features; (ii) excavating on-site soils to create the proposed Phase
Ill base grades; (iii) placing and compacting soil fill to achieve the Phase III sideslope
subgrade; (iv) processing, placing, and compacting on-site low-permeable soil within the
Phase III area; (v) constructing the Phase III primary and secondary liner and leachate
collection systems; (vi) constructing the Phase III Sump Riser Building and leachate
conveyance piping; and (v) making associated connections to the Phase II leachate and liner
systems.

SCOPE OF SERVICES

Task 1 CQA Services

Sanborn Head will provide on-site CQA personnel consisting of a Site Manager and Monitors
to perform the specific monitoring and documentation services defined in the Project’s CQA
Plan. Sanborn Head’s CQA Managing Engineer, a Professional Engineer licensed in the State
of New Hampshire, will be responsible for the implementation of the CQA services and will
oversee the on-site CQA personnel. The CQA Team will monitor the contractor’s work for
conformance with the construction documents (e.g., drawings and specifications), track the
progress of the Project, and be available to address contractor questions during the Project.

The specific services to be performed by Sanborn Head’s CQA team includes: (i) reviewing
and commenting on contractor’s submittals; (ii) documenting materials quantities installed
or items constructed by the contractor; and (iii) reviewing and commenting on contractor’s
requisitions for payment prior to submittal to the City for final approval. Sanborn Head’s
CQA Managing Engineer will visit the site regularly (typically once per week) during
construction.

SANBORN, HEAD & ASSOCIATES, INC. wwwosanbornhead.com

February 18, 2019 Page 2
20190218 Nashua Phase Ill CQA Proposal.docx

Sanborn Head’s CQA Team also will monitor the following construction activities:
= Excavation of Phase III (on a limited basis only);
= Placement and compaction of soil fill in the Phase III area;

=" Modification of existing Detention Pond #6 and the associated site drainage
improvements;

2 Decommissioning of piezometers, monitoring wells, stormwater pipes, and leachate
collection pipes;

= Installation of leachate collection and forcemain/gravity main piping outside the limit of
waste;

= Installation of the Phase IJ] liner and leachate collection systems;

= Construction of the Sump Riser Building and associated components; and

= Installation of the perimeter road and supporting infrastructure.

The CQA Team will monitor the installation of the various components of the Phase III liner

and leachate collection systems. The components of the liner and leachate collection systems
include, listed from top to bottom:

a An 18-inch thick layer of drainage sand;

= A multi-linear drainage geocomposite or a geonet drainage geocomposite;
a A 60-mil thick textured high-density polyethylene (HDPE) geomembrane;
a A geosynthetic clay liner (GCL) (sump area);

a A 12-inch thick layer of drainage sand (base area only);

a A multi-linear drainage geocomposite or a geonet drainage geocomposite (the type of
geocomposite will be dependent on contractor pricing);

a A 60-mil thick textured HDPE geomembrane; and

a A 6-inch thick layer of Screened Till.

During earthwork construction, the CQA Team will: (i) monitor excavation activities and
review survey data documenting that the subgrade elevations are achieved; (ii) monitor the
placement of earth materials; and (iii) test the in-place moisture content and density of
compacted materials. Field moisture/density testing, as required, will be performed using a
nuclear density gauge in accordance with current ASTM standards.

The CQA Team will observe and document the construction of the new site drainage
components, the leachate management system modifications, and the Sump Riser Building.
Allowed variances from the construction documents will be noted and photographed.

Sanborn Head will review manufacturers’ data regarding the quality of resins used in the
production of the geomembranes and manufacturers’ certifications for the geosynthetic
components of the liner system against the Project specifications. Only geosynthetic

SANBORN i HEAD

February 18, 2019 Page 3

materials that have the proper manufacturer documentation will be accepted for use in
construction. Conformance samples of the accepted geosynthetics will be obtained either at
the manufacturer’s facility or from material delivered to the Project site. Sanborn Head will
select the rolls to be sampled for testing at a laboratory experienced in geosynthetic testing.
Conformance test results will be reviewed before approval is given for deployment of the
geomembrane and/or geocomposite.

During construction, Sanborn Head will:

= Provide up to two Monitors to document activities. For budgeting purposes, we assume
that one Monitor will be needed throughout construction and one additional Monitor will
be needed for 4 weeks during the liner system installation;

= Collect samples for conformance testing from the geomembrane and geocomposite;

® Observe and document the geosynthetic installation contractor's work and quality
control procedures;

=" Obtain samples of earth materials including Structural Fill, Drainage Sand, Screened Till,
and roadway soils for testing at a subcontracted geotechnical laboratory;

=" Perform field moisture/density tests on compacted Structural Fill, Screened Till, and
roadway materials;

= Collect samples of welded geomembrane seams and forward them to a subcontracted
geosynthetics laboratory for destructive testing; and

a Prepare Daily Field Reports to document the day-to-day construction activities.

Task 2 Construction Meetings/Documentation

Sanborn Head’s CQA Managing Engineer and/or Site Manager will attend weekly
construction progress meetings with the contractor and the City. Construction progress
meetings are anticipated to be held weekly at the site and will include discussions about the
current work progress, planned activities for the upcoming week, and new business or
revisions to the Project. Sanborn Head will take minutes of the meetings, which will be
issued to the City, the contractor, and the NHDES. Sanborn Head will also prepare bi-weekly
summaries of the construction progress for the City's use in submitting bi-weekly progress
updates to the NHDES Solid Waste Bureau as required by the Solid Waste Rules.

Task 3 CQA Report

Sanborn Head will prepare a CQA Report that documents the observations made during
construction and includes copies of submittal review forms, geotechnical and geosynthetic
laboratory test results, pipe pressure test results, geosynthetic installation documentation
and Record Drawings. The Record Drawings will be based on the Construction Drawings
and will show the surveyed as-built locations and elevations of the Project components as
provided by the contractor. As appropriate, design details will be modified to depict the
actual installations. The CQA Report will be prepared under the direction of a Professional
Engineer licensed in the State of New Hampshire and submitted to the NHDES following
review by the City.

approximately 5 hours in duration (8 am to 1 pm Saturday).

a Construction meetings will occur weekly during construction and will be no longer than
one hour in length.

a There will be one material source for each type of earthwork material.

ua The contractor will be responsible for surveying geosynthetics and will provide the data

weeks after the Project is substantially complete. The final report will be completed and
submitted to the NHDES about two weeks following receipt of the City’s comments to the
draft report.
