Re: Change Order Request
Construction Quality Assurance Services - Phase III
City of Nashua Four Hills Landfill
Nashua, New Hampshire

Dear Jeff:

Sanborn, Head & Associates, Inc. (Sanborn Head} appreciates the opportunity to be of
continued service to the City of Nashua (City). As we recently discussed, based on the
additional requirements imparted by the New Hampshire Department of Environmental
Services (NHDES) on the Phase III construction project and the associated construction
delays, we will exceed the approved budget for the Phase III Construction Quality Assurance
Services project. This letter presents our request for a change to our budget.

Background

Sanborn Head's original scope of services, described in our proposal dated February 18,
2019, included the following three (3) tasks:

a CQA Services;
m Construction Meetings/Documentation; and
a CQA Report.

However, during construction our scope evolved to include components that were not
anticipated at the time the existing budget was established. In addition, the total length of
the project was increased due to construction and permitting delays. Our original proposal
assumed that construction would take approximately 16 weeks, and as of the date of this
letter, the Phase III construction project is currently in its 26% week of construction. The
additional time and requests for services require a change to our approved budget.

Additional Services Already Provided

Since submitting the February 2019 proposal, several requests were made that were outside
our Construction Quality Assurance Services agreement. Below is a list of the major
differences that were not reflected in our proposal:

a Preparing narratives, figures, and tables associated with the Groundwater
Demonstration required by Condition 6 of the Phase III] permit, dated December 5, 2018;

SANBORN, HEAD & ASSOCIATES, INC. www.sanbornhead.com

November 12, 2019 Page 2
20191112 Budget Increase Letter.dacx

Preparing modified base grades based on elevated groundwater readings;
Meeting with the NHDES regarding Groundwater Demonstration and revised grading;

Preparing calculations, redesigning leachate collection system components, and
compiling a Type II permit modification application at the request of the NHDES based
on the modified Phase III grading;

Updating project quantities for the selected contractor;

Preparing modified perimeter grades to offset additional fill required to construct the
Phase III modified base grades;

Developing a procedure to decommission the I/P Trench and coordinating with the
NHDES;

Meeting with the NHDES to discuss the I/P Trench decommissioning procedure;

Reviewing the contractor’s change order request, preparing a change order review
document, and communicating/coordinating with the City on our review and the City’s
position on select change order items;

Preparing for and attending a meeting with Ward 5 regarding the Phase III construction
project and the Four Hills Landfill in general; and

Providing field CQA services beyond the originally anticipated construction schedule of
16 weeks.

The cost to provide the services above was roughly $60,500 and was billed out of Task 1
CQA Services,

Remaining Scope Items

To complete our Construction Quality Assurance scope of services and to maintain
compliance with the Solid Waste Rules, we still need to complete the following tasks during
the Phase II] construction project:

Provide CQA services (approximately 4 more weeks of full-time and part-time coverage
based on the projected construction schedule provided by Charter - see enclosed). The
additional field coverage time that our budget increase assumes for this task is included
in the enclosed schedule and is also summarized below:

o 3 days of full-time coverage for “ramp” subgrade and geosynthetics installation.

o Field visit check-ins once the liner system components are installed “as needed.” For
the purposes of this budget increase, we assume 7 check-ins.

Provide laboratory testing services for soils and geosynthetics;

Prepare for and attend weekly construction meetings - we recommend reducing the
construction meetings to occur bi-weekly [{i.e., every other week} to reduce costs
considering the limited amount of work that remains. For the purposes of this budget
increase, we assume there will be 3 more construction meetings;

Prepare bi-weekly construction summaries to NHDES. We assume 3 summaries will be
required for the remainder of the project;

ns Update the facility’s operating, closure, and financial assurance plans to satisfy permit
conditions; and

w Prepare the CQA Report and Record Drawings for submittal to the NHDES.

Budget Adjustment

The original budget for each task under this scope of services is provided in the table below
along with the proposed adjusted budget that we believe is required to finish out the
Construction Quality Assurance Services project. The proposed adjusted budget is based on
the estimated time commitment required to complete the remaining services described
above in addition to expenses associated with material conformance testing, printing,
mileage, and tolls.

Original Proposed | Proposed
Task Task Description B Budget Adjusted
udget
Increase Budget
1 CQA Services $217,500 $75,500 $293,000
Out of Scope Items & Schedule Extension - $60,500 -
Remaining Field Services - $15,000 -
2 Construction Meetings/Documentation $17,500 $4,200 $21,700
3 CQA Report $20,000 - $20,000
4 Permit Conditions Support - $10,000 $10,000
Total | $255,000 $89,700 $344,700

Based on our discussions with the City, Task 4 was added to separate out the proposed costs
to prepare the documents associated with the Phase III permit conditions that will be
submitted to the NHDES prior to the Notice of Intent to Operate application. We are not
including the cost to prepare the Financial Assurance Update as that was already budgeted
to be completed under our General Engineering Services agreement.

Acceptance

We understand that acceptance of this budget adjustment will be provided in a City issued
Purchase Order to Sanborn Head for these services.

RE: Communication to Approve-&- Place on File a Notice of Contract Amendment

Change For Nashua Housing Study / Inclusionary Zoning Study.

In the fall of 2020 the Community Development Division, in partnership with Economic Development,
received quotes to complete a comprehensive housing study in order to understand the dynamics in
Nashua and our region that impact housing supply and demand. The City chose RKG Associates to
complete the housing study as their costs and proposal were the best fit for the City. The Housing Study
was completed in October of 2020 and the City was very satisfied with the work of RKG Associates. This
initial contract was for $24,650.

A second phase under a new contract occurred in the spring of 2021 where in continuing the Housing
Study, as stated in recommended strategies, the City would need to update its Inclusionary Zoning
ordinance to encourage affordable housing throughout the city and ensure the City’s ordinances are
financially feasible. RKG recently concluded the initial financial feasibility analysis and provided a
detailed model which allows for the city to overhaul its inclusionary zoning ordinance if it so chooses. A
presentation to the Board of Aldermen was given on September 28, 2021. This second phase of work was
done for $22,750.00.

I am now requesting a third phase as outlined in the proposed scope of work where RKG will assist in
develop a piece of legislation based on the prior work. RKG will be available to participate in meetings
and provide technical guidance on this subject as Director Marchant and I will be working with various
stakeholders to craft a suitable public policy. This effort will take an additional $23,200.00 and is being
offered as an amendment to the most recent contract.

As RKG Associates recently completed the prior housing study work for the city, they have the detailed
information and specific experience to complete this work most efficiently and cost effectively.

The total project costs over the two contracts is $70,600.00 and this $23,200 request as an amendment
will be funded through an Economic Development Escrow.

Re: Inclusionary Zoning Financial Feasibility Analysis

In the fall of 2020 the Community Development Division, in partnership with Economic
Development, received bids to complete a comprehensive housing study in order to understand the
dynamics in Nashua and our region that impact housing supply and demand. The City chose RKG
Associates to complete the housing study as their costs and proposal were the best fit for the City.
The Housing Study was completed in October of 2020 and the City was very satisfied with the work
of RKG Associates.

In continuing the next steps of the Housing Study, as stated in recommended strategies, the City
needs to update its Inclusionary Zoning ordinance to encourage affordable housing throughout the
city and ensure the City’s ordinances are financially feasible.

As RKG Associates recently completed the City’s Housing Study, they have the detailed
information and specific experience to complete this work most efficiently and cost effectively.

The scope of this second contract with RKG Associates will be for them to perform a financial
feasibility analysis and provide a detailed model which will allow the city to overhaul its
Inclusionary Zoning ordinance to ensure the ordinance is in line with market conditions. In addition,
this project will result in a report which will provide a series of recommendations on how the City
can enact a more comprehensive and effective inclusionary zoning ordinance while mitigating any
potential adverse effects to the financial feasibility of new multifamily residential development.

The total contract is $22,750 and will be funded through the Community Development Department.
