1.1 SUMMARY OF WORK

A. Background and Objectives:

1. The buildings comprising the Saddlehorn Historic District at Colorado National

Monument (of which the R&T [Road and Trails Shop], B&U [Building and Utility Shop], and Cold Storage Building are a part) were constructed by the Civilian Conservation Corps between 1935 and 1942, and now serve as administrative and service headquarters for the Park. The three sandstone structures in this project serve as facilities shops, and their effective functioning has been compromised by 60-year-old garage doors that no longer function correctly nor provide adequate protection from the elements and pests. Replacement of the 1960’s-era garage doors will improve the garage functions and the building thermal and envelope performance, while retaining a similar aesthetic to the modifications from the 1960’s (as opposed to the CCC-era).

2. The objective of this project is to address the existing overhead garage doors (also called sectional doors) (a total of 5, varying in size) on the R&T , B&U, and Cold Storage Buildings at the historic Saddlehorn Utility District, which are at the end of their useful lives and no longer provide effective barriers against the elements.

B. Work Covered by the Contract Documents: The project will remove and dispose of existing doors (panels, tracks, controls, and wiring) and replace in-kind existing garage doors with new high R-value heavy-duty commercial sectional doors (panels, tracks, wiring, motors, stationary and remote controls) and rodent-proof weather-stripping. Door panels will maintain vision lites for natural lighting. Repair to adjacent finishes will be included where affected in this Work.

The project will improve the quality and function of the doors and provide increased energy efficiency, thermal comfort, and security for the buildings and occupants by preventing rodent infestation and wind/rain penetration of the building envelope.

C. Project Location: The project Place of Performance includes three separate buildings, all located near one another in the Saddlehorn Historic District at Colorado National Monument.

Colorado National Monument is approximately 5 miles west of Grand Junction, Colorado.

1. R&T (Road and Trails) Shop/Equipment Shed (Building 4)

SECTION 013591 - HISTORIC PRESERVATION TREATMENT PROCEDURES

PART 1 - GENERAL

1.1 SUMMARY

A. This Section includes special procedures for historic treatment on the Project including, but not limited to, the following:

1. Storage and protection of existing historic materials.

2. Temporary protection of historic materials during construction.

3. Protection during use of heat-generating equipment.

4. Historic preservation treatment procedures.

1.2 DEFINITIONS

A. "Preservation": To apply measures necessary to sustain the existing form, integrity, and materials of a historic property. Work may include preliminary measures to protect and stabilize the property.

B. "Rehabilitation": To make possible a compatible use for a property through repair, alterations, and additions while preserving those portions or features that convey its historical, cultural, or architectural values.

C. "Restoration": To accurately return the form, features, and character of a property to its appearance at a particular period of time by means of the removal of features from other periods in its history and the repair and reconstruction of missing and deteriorated features from the restoration period.

D. "Reconstruction": To reproduce in the exact form and detail a building, structure, or artifact as it appeared at a specific period in time. Reconstructed elements do not possess historic integrity in their own right since it is not original fabric.

E. "Stabilize": To apply measures designed to reestablish a weather-resistant enclosure and the structural reinforcement of an item or portion of the building while maintaining the essential form as it exists at present. This level of intervention is aimed at retarding or arresting adverse impacts to structures.

F. "Protect and Maintain": To remove deteriorating corrosion, reapply protective coatings, and install protective measures such as temporary guards; to provide the least degree of intervention.

G. "Repair": To stabilize, consolidate, or conserve; to retain existing materials and features while employing as little new material as possible. Repair includes patching, piecing-in, splicing, consolidating, or otherwise reinforcing or upgrading materials. Within restoration, repair also includes limited replacement in kind, rehabilitation, and reconstruction, with compatible substitute materials for deteriorated or missing parts of features when there are surviving prototypes.

COLM - 240946 013591 - 2

H. "Replace": To duplicate in its entirety a historic element or feature by matching its historic pattern, detail and appearance. . Replacement is justified when original or historic elements are damaged beyond repair or are missing. Replacement methods includes the following conditions:

1. Replacement with Original or Historic Fabric: Includes fabric salvaged from other locations or projects having identical architectural qualities. It means duplication of appearance using identical material possessing historical significance.

2. Replacement with New Materials: Includes replacement with new material of like kind

(custom fabricated of manufactured) that is currently in production. It means duplication of appearance using like material.

3. Replacement with Substitute Materials: Includes replacement with a compatible substitute that is frequently contemporary and unlike the historic fabric. It means duplication of appearance using modern (non-traditional) material Use of substitute materials is not approved unless matching materials are not available.

I. "Remove": To demolish or detach items from existing construction and legally dispose of them off-site unless indicated to be removed and salvaged or removed and reinstalled.

J. "Remove and Salvage": To detach items from existing construction and deliver them to the

NPS.

K. "Remove and Reinstall": To detach items from existing construction, repair and prepare them for reuse, and reinstall them where indicated.

L. "Existing to Remain" or "Retain": Existing items of construction that are not to be removed and that are not otherwise indicated to be removed and salvaged, or removed and reinstalled.

M. "Material in Kind": Material that closely matches existing materials, through comparison of architectural qualities and salient characteristic such as species, cut, color, grain, , dimension, profile, thickness, and finish.
