BACKGROUND

The City of Somersworth is requesting bids from qualified Contractors to replace and repair the roofing on two City of Somersworth facilities:

I. The Water Treatment Facility, 9 Wells St., Somersworth, NH consists of two roof sections that require replacement. The original facility was constructed in 1895 and has a high slope slate roof with copper flashing (approximately 4,300 square feet, Contractor to field verify). An addition to the water treatment facility was built in 1991 and has a low slope membrane roof (approximately 9,000 square feet, Contractor to field verify).

The low slope membrane roof is to be replaced in kind with additional rigid insulation to be provided. However, there are two alternates for the work proposed for the high slope slate roof:

Alternate 1: Repair of the existing slate roof in place, or

Alternate 2: Remove and replace the slate roof with an asphalt shingle roof.

There is an alternate for replacing the existing rolled copper gutters with new rolled copper gutters as follows:

Alternate 3: Remove and replace existing copper gutter with new quarter round integrated solid copper gutter with copper straps and fasteners and repair/replace fascia as needed for a complete installation.

II. The Wastewater Treatment Facility, 99 Buffumsville Road, Somersworth, NH has a low slope ballasted membrane roof (approximately 13,875 square feet, Contractor to field verify). This membrane roof is to be removed and replaced in kind.

The City is requesting a bid for each facility, and a total for both facilities. Although the City desires to contract with a single Contractor for both facilities, the City reserves the right to award each contract individually if it is determined to be in the best interest of the City.

Pre-Bid Walk Through Inspection: A non-mandatory pre-bid walk through inspection of

each facility roof has been scheduled for July 10, 2014 at 1:00PM The City highly

recommends that all Contractor’s bidding on the projects attend the Pre-Bid walk through.
