Safety Equipment Purchase

To approve the purchase of the Gorbel Road Ranger Fall Protection Unit from
Mass Crane and Hoist Services, Inc. of Tyngsboro, MA in the amount not to
exceed $46,202. Funding will be through Department: 169 Wastewater; Fund:
Wastewater; Activity: Davit ARM Replacement.

The Wastewater Department has unique safety needs, with many tanks being
greater than 20 feet in depth and requiring personnel entry in order to clean and
maintain the structures. Recently we began a Facility wide project to increase
safety in the way we enter tanks and pump stations, with the installation of Davit
arms in the Wet Weather Facility Screening Upgrade, the Primary Upgrade, and
the Pump Station Upgrade.

In order to easily and cost effectively address the safety in the majority of areas,
the wastewater department would like to purchase a mobile fall protection unit.
The Facility explored two units, each that would meet the needs of the Facility.
One unit is the Gorbel Road Ranger, the other being the Malta Dynamics X1250.
We could not find a third comparable unit. The Gorbel Road Ranger has a lower
cost and meets the application needs of the Facility, making this the
recommended purchase. The quote received for the Gorbel Road Ranger was
from Mass Crane and Hoist for $46,202, which includes delivery.

2022 Sewer Replacement Project - SUR West Change Order No. |

To approve Change Order No. | to the 2022 Sewer Replacement Project with SUR
Construction West, Inc. of Winchester, NH for an amount not to exceed $500,000.00.
Funding will be through Department: 169 Wastewater; Fund: Bonded; Activity: Sewer
Repair.

2022 Sewer Replacement Project, Change Order No. 1

SUR Construction West was contracted for the 2022 Sewer Replacement work under
IFB0779-021022. SUR West has been our sewer contractor since 2020, and we have
found their work to be excellent and reasonably priced. Through completed Close Circuit
Television (CCTV) pipe inspection work, we have identified additional sewer pipe that
needs repair or replacement. The Engineering Department is finalizing plans for work on
Factory St and Lock St and would like to secure funding for construction this fall. The
purpose of this Change Order is to expand SUR Construction West’s contract to include
replacement of additional deteriorated sewer pipes.

The above change order will allow for repair or replacement of deteriorated pipe segments
and accompanying sewer structures and sewer services, if necessary. If portions of these
pipes are found to be in satisfactory condition, or suitable for lining, they will be retained
and funds used for repair or replacement of other sewer pipes and structures found to be
in disrepair through the City’s ongoing CCTV work.

CHANGE ORDER

No. l
PROJECT: 2022 Sewer Replacement Project
OWNER’S CONTRACT NO: IFB0779-021022
EXECUTED CONTRACT DATE: 04/18/22
DATE OF ISSUANCE: 07/28/22 EFFECTIVE DATE: Upon City Approval
OWNER: City of Nashua, NH
OWNER’s Purchase Order NO.: 171057
CONTRACTOR: SUR Construction West, Inc.
ENGINEER: DPW Engineering

You are directed to make the following changes in the Contract Documents:

Description:

The City’s sewer pipe CCTV program has identified some pipes in need of replacement. These pipes
have deteriorated too far to be CIPP lined. To date, approximately $500,000 of work has been
identified on Lock Street and Factory Street and as the 2022 CIPP video and lining contract begins in
earnest more deficient pipes and structures are expected to be found.

The Engineering Department would like to extend our contract with SUR Construction West through
2022 by issuing a change order. SUR has agreed to hold their 2022 bid pricing with the exception of
any increases in material or oil prices. Those increases will need to be approved by the Engineering
Department prior to any work issued under this change order.

Justification:

At this time, only a portion of the sewer replacement work expected to be necessary in 2022 has been
identified. In particular, more work is expected on Lock St and Factory St. And with the
commencement of the 2022 CIPP Lining project in August 2022, more crumbling sewer pipe is
expected to be found via closed circuit television (CCTV). Waiting to perform this pipe replacement
risks loss of sewer service and collapse of the road above the pipe. SUR West was contracted under
IFB0779-021022 to perform the City’s 2022 sewer work and is actively working in Nashua. A change
order to retain SUR West in 2022 is more advantageous to the City than bidding a new sewer
replacement contract.

Canal St Bridge Repairs — Change Order No. 2

To approve Change Order No. 2 for the Canal St Bridge Construction Repairs
contract in an amount of $34,000. Funding will be through Departments 160
Admin/Engineering & 161 Street; Funds: Capital & Grant; Activities:
Infrastructure Improvements & Highway Block Grant.

The Canal Street Bridge over the Nashua River is part of a critical east-west arterial
roadway traversed by approximately 30,000 vehicles per day. NHDOT periodically
inspects the bridge and has given it a rating of poor for the substructure, due to
concrete issues at the east abutment and center pier. Repairs to a portion of the
bridge barrier are also necessary. Engineering consultant Fuss & O'Neill, contracted
by Engineering, provided the design of the repairs and is currently providing
construction services. New England Infrastructure, Inc. of Hudson, MA is
contracted for the construction repair work. A Notice to Proceed was issued for
work to start on June 16, 2022 and work is currently underway.

The original contract amount to New England Infrastructure was $373,750.
Following the start of construction, during low water conditions, we have observed
that the necessary repair areas have grown since their assessment at the time of
design. Concrete distresses in both the east abutment and center pier have increased.
In addition, a concrete sidewalk in proximity of the work has cracked and needs
replacement. A Change Order No. 1 for $23,561.86 was administratively approved
for the water diversion work necessary for the additional pier repairs and for the
sidewalk repairs.

This proposed Change Order No. 2 consists of three parts:
e Concrete preparation (removal of weak concrete): $12,000
e New concrete placement: $12,000
e Allowance for unforeseen repairs needed: $10,000

The allowance is being added due to some remaining uncertainty of full scope of
necessary repairs, which can only be fully investigated once the additional
dewatering is complete and the structure is fully visible. With Change Order No. 2
approval, the amended construction contract total will be $431,311.86. All work is
expected to be completed this year.
