2019 Paving Program — Arterial Roadways
Construction

To approve the construction contract for the 2019 Paving Program - Arterial Roadways to
Brox Industries, of Dracut, MA in the amount of $6,853,472.96. Funding will be
through: Department: 160 Admin/Engineering; Fund: Bond and Trust; Activity: Paving.

2019 Paving Program — Arterial Roadways Paving List
The 2019 Paving Program has been divided into two sections:

e Arterial Roadways
e Local and Collector Roadways

The paving program was divided to attract bids from a broader range of paving contractors
since the scope of the work is different for the two types of roadways. It has also been
divided to hopefully have two separate contractors to share the 23 miles of work.

The 2019 Paving Contract for Arterial Roadways is expected to pave approximately 11.6
miles of streets. The contract uses repair methods such as shim, overlay, milling and
reclamation. It also includes replacing obsolete and broken drainage and sewer castings.

The contract was advertised on January 17, 2019. Three contractors attended the
mandatory pre-bid meeting and they submitted bids on February 12, 2019 and are listed
below:

Brox Industries, Inc. of Dracut, MA $6,853,472.96
Newport Construction Corporation of Nashua, NH $7,685,165.20
Continental Paving Inc., Londonderry, NH $7,995,896.45

Brox Industries, Inc. of Dracut, MA at a bid price of $6,853,472.96 is the qualified low
bidder. Brox has completed many years of annual paving for the City, and has done many
large projects for the NHDOT. Brox is capable of completing this project to our
satisfaction.
