BACKGROUND

The U.S. Merchant Martine Academy (USMMA) is a federal service academy that educates and graduates licensed merchant marine officers who serve America’s marine transportation and defense needs in peace and war. It is part of the Maritime Administration (MARAD), U.S. Department of Transportation.

The USMMA is seeking a qualified contractor, experienced in historical restoration, to provide labor, material, tools, and equipment to restore the roof on the American Merchant Marine Museum (AMMM), which is located at 300 Steamboat Road, Great Neck, New York on the USMMA campus. Both the USMMA and the AMMM are listed on the National Register of Historic Places; USMMA as a National Historic District with the AMMM listed separately.

http://www.marad.dot.gov/wp-content/uploads/pdf/Barstow_House_NR_Nomination.pdf.

The property is considered historically significant on a statewide level as a reminder of the “Golden Age” of the late nineteenth and early twentieth centuries. It is a Mediterranean Revival style that reached its final form with a major reconstruction in1930-1931. The three-story dwelling is of stucco with a terra-cotta tiled roof. The property consists of two contributing features— the William S. Barstow Mansion (the museum) and garage—which retain their integrity from the period of significance, 1915–1960. Therefore, all work shall be consistent with the Secretary of the Interior's Standards for the Treatment of Historic Properties (36 CFR part 68) http://www.nps.gov/tps/standards/four-treatments/treatment-guidelines.pdf.

Additionally, all work shall meet or exceed the standards provided by the Secretary of the Interior’s Standards for Rehabilitation and Illustrated Guidelines on Sustainability for Rehabilitating Historic Buildings http://www.nps.gov/tps/standards/rehabilitation/sustainability-guidelines.pdf and 36 CFR 67.7 - Standards for rehabilitation. http://www.nps.gov/tps/tax-incentives/taxdocs/36cfr67.pdf

SCOPE

The AMMM’s current roof consists of clay mission style barrel tiles. The roof requires restoration, with repair work being needed on the structure just below the tiles. The existing clay tiles will be salvaged and reused providing the tile is still reusable. Tiles needing replacement will be replaced with similar, sound, clay barrel tiles so that the entire roof resembles the original roof. The roof area to be restored is approximately 4,600 square feet.

The USMMA and MARAD’s objective in restoring the AMMM roof is to avoid an adverse effect. The replacement and repairs will prevent the exterior of the building from being penetrated by moisture providing weatherproofing to keep out rain, cold or heat. It must be strong enough to withstand high winds, shed water and bear the weight of heavy snow loads. To accomplish this, it has been determined that 70% of the tile and underlying structure may be salvaged for reuse, ±10%. A contractor, with extensive experience in working on historical structures, will provide methods and material options for the USMMA and MARAD to approve and consider. Should the Contractor determine that less than 70% ±10% of the tile and underlying structure is salvageable, written and visual justification must be provided to the COR for the Government to verify. Any discrepancies in justification will be the responsibility of the Contractor.
