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.
