2019 Paving Program — Local & Collector Roadways Paving List

The 2019 Paving Program has been divided into two sections:

1. Arterial Roadways

2. 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 (Local & Collector Roadways) is expected to pave
approximately 11.4 miles of City 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 23, 2019. Four contractors attended the
mandatory prebid meeting. Three contractors submitted bids on February 13, 2018 and
are listed below:

Sunshine Paving of Hudson, NH $4,350,642.35
Brox Industries, Inc. of Dracut, MA $4,793 ,285.25
Newport Construction Corporation of Nashua, NH $4,969,669.69
Continental Paving, Inc. of Londonderry, NH $5,543,957.00

Sunshine Paving of Hudson, NH at a bid price of $4,350,642.35 is the qualified low
bidder. Sunshine Paving has completed two previous annual paving contracts for the City.
References were checked for more recent work in other communities and good responses
were received.
