coring to drill through obstructions, if encountered. Borehoies will be backfilled with drill
cuttings and grout at the ground surface. Boreholes will not be left open overnight without
protection.

We have assumed 3 days of drilling using a truck mounted drilling rig to complete the above
field program. Work will start at $ AM and be completed by 3 PM each day. Two flaggers and
one police detail has been budgeted for each day of drilling. A street opening permit from the
City of Nashua and Dig-Safe Utility clearance will be obtained by our Drilling Subcontractor (New
England Boring).

We note that we have included a contingency for Sewer Line Mark-out as a separate line item.
If the sewer line is not marked prior to drilling, we will vacuum extract the soils to a depth of 5 ft
below existing grades at the additional cost indicated.

Arrange to have the explorations made by a subsurface exploration contractor.

Prepare a project specific Health & Safety Plan for the protection of our personnel during drilling
of the borings.

Layout explorations in the field by taping or pacing distances from existing site features, and
determine approximate ground surface elevations relative to topographic information provided
by others.

Provide technical monitoring of subsurface explorations so that depths and locations of
subsurface explorations, as well as sampling methods, can be varied to meet the subsurface
conditions encountered. Provide logs of subsurface explorations.

Perform laboratory tests on soil samples recovered from subsurface explorations. We have
budgeted up to 6 grain-size distribution tests.

Prepare a brief geotechnical engineering report presenting the results of the field and
laboratory testing program. Comment on the feasibility of the conceptual drain system.

Provide other geotechnical consultation or attendance at meetings, as requested and
authorized.

Key Assumptions

The scope of work and fee proposed herein are based on the following additional assumptions:

ramps, and

Speed Radar Feedback Signs at Birch Hill Elementary School

To approve the contract with Moulison, LLC of Biddeford, ME in the amount of $28,220 for the purchase
and installation of two speed radar feedback signs and the use of Quadrant Trust Funds in the amount of
$10,300 for this contract. Funding will be through Department 160 Engineering; Funds: Grant and Trust;
Activity: Safe Routes to Schools — Birch Hill.

Bid Schedule for Variable Message Radar Speed Feedback Sign on Dublin Ave as submitted by
Moulison, LLC.

The City of Nashua was awarded Safe Routes to School funding for the purchase and installation
of some solar speed feedback signs in the vicinity of the Birch Hill Elementary School. The
purpose of the speed feedback signs is to alert motorists of their speeds as they approach this
area with the goal of slowing down traffic. The speed feedback signs would be located at the
following locations:

Location 1: Along Dublin Ave north of Dunbarton Drive facing southbound traffic.
Location 2: Along Dublin Ave south of Woodland Drive facing northbound traffic.

Each of the signs would include a solar panel, a flashing beacon, a 1” minimum LED message
matrix, and a 1”-3” minimum LED Radar Digits showing speed feedback. The signs will be
mounted on a steel pole into a sign support anchored into a concrete foundation.

The Safe Routes to School Funding Program is funded through Federal Highway Funds and
needs to meet all of the Federal Highway requirements. The City recently advertised this
project and received two bids as follows:

Moulison, LLC — Biddeford, ME - $28,220
Liddel Brothers — Halifax, MA - $39,000

The City recommends award the contract to Moulison, LLC in the amount of $28,220. The
City would use the $17,920 of Safe Routes to School funding (pending final State of New
Hampshire DOT approval). The City will need to use $10,300.00 from the Corridor Funds
account to fund the additional amount. The City does believe the recent bid of $28,220 is
reasonable. There have been changes in technology, and the original grant application was
prepared in 2014.
