City of Nashua, Public Works Division

Board of Public Works Meeting Date: July 27, 2017

Stephen Dookran, P.E., City Engineer

2017 Paving Program — Phase 2 — Construction
Change Order No. 2 to FY16 Brox Contract

To approve Change Order No. 2 to the paving contract for the FY16 Paving Program to
Brox Industries, Inc. (Brox) of Dracut, MA in the amount of $ 2,058,630.00. Funding will
be through Department: 160 Admin/Engineering; Fund: General; Activity: Multi-Years
Paving. Department: 169 Wastewater; Fund: Wastewater; Activities: Sewer Structures

Change Order No. 2

As the expanded program for street paving was approved and funded in July 2017, a list of
residential streets was selected. The change order 2 is expected to pave approximately 6.5
miles of residential streets in City of Nashua. The list of streets to be paved under this
change order is attached.

Due to limited time and resources, paving bid documents/contract could not be prepared,
advertised, and solicited. Therefore, Brox was asked if they have the capacity to pave
approximately 6.5 miles of streets and would hold the prices of FY16 contract (Contract #
IFB0660-020316), to which they agreed. Also, attached is a copy of the email confirming
the same from Brox staff. This approval is for the paving of additional residential streets.

The approach used for selecting the streets for repaving is to choose to maximize its
available roads funds by generating a Network Priority Ranking (NPR) that favors cost-
effective repairs that improve and/or maintain salvageable pavement segments. This would
delay repair actions on those segments that require reconstruction or major rehabilitation.
After the relatively good roads are “preserved”, future repairs will be directed towards the
poorer, heavily traveled roads.

The additional streets were selected based on a Pavement Condition Index (PCI) of 45 or
lower or streets with the highest benefit values. Preservative maintenance treatment will
be applied to roads that are showing signs of age to extend the life of the pavement by
protecting them using a variety of techniques. These selected residential streets fall in
structural improvement PCI Band #4 (68-42 PCI) and are in poor condition. The pavement
surface has deteriorated beyond the need for surface maintenance application, therefore 2-
inch mill & overlay will be performed before the road deteriorates further and is in need of
full depth reconstruction/reclamation. Other work required includes replacing obsolete and
broken drainage and sewer castings, repairing/replacing catch basins and manholes,
replacing sewer and drain pipes, addressing street drainage problems, restriping,
replacing/resetting curbing and reconstructing driveway transitions.

The total value of Change Order No. 2 is $2,058,630.00. With Change Order No. 2, the
total contract value is $ 4,686,532.45.

condition of the street has deteriorated and it might have to be reclaimed. We have not made a final decision on that
street. All the streets on the list will have 2-inch mill & Overlay. We estimate that approximately 119,000 square yards of
road will be milled and approximately 13,041 tons of asphalt will be laid on roads. As these streets are in old residential
neighborhood, we are not sure of the thickness of the pavement. Early next week we will be installing a core on each
street to verify the thickness of the pavement. For estimation purpose, | have assumed 2-inches pavement thickness in
our calculations. Once we will have the pavement thickness information next week, we will have better tonnage
information for you.

2017 Street Paving Program — Construction
Change Order No. 1

To approve Change Order No. | to the construction contract for the FY17 Paving
Program to E.J. Paving Company, Inc. of Methuen, MA in the amount of
$474,205.00. Funding will be through: Department: 161 Street; Fund: General;

2017 Street Paving Program Change Order No. 1

The 2017 Street Paving Program, in the amount of $1,729,148.30, was awarded to EJ
Paving Company, Inc. of Methuen, MA in March 2017. The contract included
paving of approximately 5.6 miles of City streets including 2,500 feet of Main Street
and 3,100 feet of West Hollis Street and uses repair methods such as shim, overlay,
milling and reclamation. It also includes replacing obsolete and broken drainage and
sewer castings.

Contract language allows for streets to be substituted based upon their status (i.e.;
some streets may be delayed due to utility conflicts or emergency repairs, other
streets may require postponement due to larger issues, streets may also be added that
need immediate repairs) and several streets in the program fall into these categories.
At the same time, Tinker Road has deteriorated from last winter’s effects faster than
expected and it has been determined that it should be added to this year’s paving
program immediately. The approximately 1.7 miles of Tinker Road requires paving,
milling, casting adjustments/replacements, and striping. As other streets previously
in the contract were delayed, the work on Tinker Road was substituted into the
contract. In order to complete the streets that Tinker Road was substituted for, this
change order adds back those streets bumped by Tinker Road.

Change Order 1 adds $474,205 to the contract. Also included in the change order is
the installation of roughly 500 feet of granite curbing for sidewalk (to be constructed
by the Street Department) on Fairway Street.

Proposed changes have been reviewed the E.J. Paving, Inc and have been accepted.
See attached agreement and change order schedule of values. Change Order No. 1
results in a revised contract value of $2,203,353.30.
