1.0 Background

The Longfellow-Washington’s Headquarters National Historic Site, also known as the Vassall- Craigie-Longfellow House, is a historic site located at 105 Brattle Street in Cambridge, Massachusetts. For almost fifty years, it was the home of noted American poet Henry Wadsworth Longfellow. For a time, it had previously served as the headquarters of George Washington.

The house was built in 1759 for John Vassall, who fled the Cambridge area at the beginning of the American Revolutionary War because of his loyalty to the king of England. George Washington used the abandoned home as his first official headquarters as commander of the Continental Army; the home served as his base of operations during the Siege of Boston until he moved out in July 1776. Andrew Craigie, Washington's Apothecary General, was the next person to own the home for a significant period of time. After purchasing the house in 1791, he instigated the home's only major addition. Craigie's financial situation at the time of his death in http://en.wikipedia.org/wiki/Cambridge,_Massachusetts http://en.wikipedia.org/wiki/Cambridge,_Massachusetts http://en.wikipedia.org/wiki/Henry_Wadsworth_Longfellow http://en.wikipedia.org/wiki/Henry_Wadsworth_Longfellow http://en.wikipedia.org/wiki/George_Washington http://en.wikipedia.org/wiki/George_Washington http://en.wikipedia.org/wiki/American_Revolutionary_War http://en.wikipedia.org/wiki/Continental_Army http://en.wikipedia.org/wiki/Siege_of_Boston http://en.wikipedia.org/wiki/Apothecary_General

1819 forced his widow Elizabeth Craigie to take in boarders. It was as a boarder that Henry Wadsworth Longfellow came into the home. He became its owner in 1843, when his father-in-law Nathan Appleton purchased it as a wedding gift. He lived in the home until his death in 1882.

The last family to live in the home was the Longfellow family, who established the Longfellow Trust in 1913 for its preservation. The home was donated in 1972, along with all its furnishings, and was made part of the National Park Service. The home, which represents the mid-Georgian architectural style, is seasonally open to the public.

2.0 Scope, quantities, and specifications

A site visit is recommended to view the existing wooden shutters but not necessary. There are 4 styles of wooden shutters that need to be constructed. Pictures are in an attached document with dimensions and quantities. Attachement is only a guide for estimating purposes. Final details will be finalized after award. There will be less than 2% deviation from the guide. For example, the guide may show a stile reveal of ½” which may really be ¼” or one stile may have a ¼” half round bead when it may be discovered to have a ½” round bead. Detail change will have very minimal impact on pricing. No shutter hardware is needed in this contract. There will also be a list provided below.

These shutters are historic, certain features like a half round bead most likely will not be of a modern standard type of bead. In this case, a modern standard half round bead is acceptable.

There is no need to customize a cutter to duplicate this feature. Use of modern, readily available cutters are acceptable. The intent of this contract is not to produce an exact replica of the historic shutter but rather to produce wooden shutters that follow the provided specifications. One sample of each shutter will be delivered to the awarded contractor for guidance. Again, the purpose is not to duplicate the exact shutter. The purpose is to produce wooden shutters with the same dimensions and details provided below using modern cutters, materials, and methods. No special customizing of blades is necessary.

Specifications for each style:

1. All dimensions are to be read as: thickness x width x length

2. Each style shall be made entirely of Spanish Cedar or Basswood, free of defects such as bows, warps, twists, knots, blemishes. All materials shall be Grade “A”.
