NOVEMBER 2018 SUMMARY OF WORK 011000 - Page 3 of 12

E. Existing Condition Information:

1. Set on a hill on the west side of the Concord River, the Stedman Buttrick House is a prominent, locally-significant resource within the North Bridge Unit of Minute Man National Historical Park. Erected in 1911 for prominent Concord businessman Stedman Buttrick, on land that the Buttrick family had owned since the 17th century, the two-and-one-half story residence was designed by Boston architect James A. Purdon. The building was converted in the 1960s to its current use as administrative offices for the Park and a visitor center for the North Bridge Unit.

2. The Stedman Buttrick House provides a variety of offices and meeting rooms, an interpretive exhibit and video program, and an Eastern National Museum store. Visitors tour the first story of the house to learn about the events of April 19, 1775 at the North Bridge and receive orientation by interpretive staff to other programs and areas of the park.

3. The building will remain occupied by staff throughout the construction period of performance; existing means of egress will be kept clear and free of obstructions.

4. With the understanding that renovations to foyers, corridors and public restrooms will necessitate temporary closures and alternative accommodations, it is the Park’s intention to keep visitor center functions open to the public throughout the construction period.

F. Existing Historical Information:

1. Project includes construction activities involving a property listed on the National Register of Historic Places.

1.3 RELATED DOCUMENTS

A. All Project Documents and Modifications made part of Contract by inclusion or reference, and apply to this Section.

B. Documents related to this Section include, but are not limited to, following:

1. Federal Acquisition Regulation (FAR), being the Contract for Project.

2. Division 00, with attention directed to:

a. Document 006000 - NER NPS PROJECT FORMS.

3. Division 01, all Sections of General Requirements, with attention directed to:

a. Section 012700 - DEFINITION OF CONTRACT LINE ITEMS.

4. Divisions 02 through 49, all Material Specifications of Project Manual appropriate to Project.

5. Project Drawings.

1.4 PROJECT DOCUMENTS

A. Project Contract:

1. Federal Acquisition Regulation (FAR), SF 1442 - Solicitation Offer and Award, and

Modifications as issued by Government.

B. If a discrepancy appears between Technical Specifications and Drawings and Federal Acquisition Regulations (FAR), FAR governs.

1. Access FAR at: www.acquisition.gov/far

NOVEMBER 2018 SUMMARY OF WORK 011000 - Page 4 of 12

C. Discrepancy concerning the figures, Drawings, and Technical Specifications shall be promptly submitted to Government, who will issue a determination in writing.

1. Adjustment without determination will be at no cost to Government.

1.5 BUY AMERICAN ACT

A. Project to be compliant with the Buy American Act for construction materials.

1. See FAR 52.225-9.

1.6 SYSTEM OF MEASUREMENT

A. It has been determined by Government that use of metric measurements and units is impracticable for Project and may cause inefficiencies. Thus, imperial measurements, also known as inch-pound units, will be cited and utilized throughout Project for layout and physical execution of construction.

1. Determination is based upon the fact that the historic structure was originally conceived and constructed utilizing imperial measurements.
