GUIDANCE FOR DESCRIPTIONS OF WORK



In order for the SHPO to accurately assess the effect of a project on a historic resource in a timely manner, a complete description of the proposed work is required. This documentation may consist of some or all of the following information (depending on the complexity of the project): architectural plans, elevations, sections, details, photographs, written specifications, and historic structure reports. For some projects only written specifications (sometimes informally done as a work "write-ups") are provided. In conjunction with the completed Historic Preservation Resource Identification Form and survey photographs, a written specification may be sufficient. The minimum documentation necessary to describe a project varies with the historic resource in question and with the magnitude of the proposed undertaking. However, all construction documentation should clearly describe the complete undertaking in detail.

The SHPO documentation requirements which follow are provided to facilitate the applicant's documentation process and to insure the expedition of all evaluations of the effect that an undertaking may have upon a historic resource. These are the standards for all work proposals, detailed work plans, work write-ups, and construction documents which are included in submittals made to the SHPO as part of the review process.


ARCHITECTURAL PLAN, ELEVATION, AND SECTION REQUIREMENTS:


Drawings must be to scale, legible, and large enough to allow the accurate rendering of the thickness of the walls. New construction elements, historic contruction elements, and existing but not historic construction elements should be drafted on one plan, but separate plans may be substituted if demolition and new work descriptions are extensive or complicated.


ARCHITECTURAL DETAIL REQUIREMENTS:


Details must be to scale and legible, and they must depict the relationship of the new construction to the pertinent components of the historic construction. Dimensions must be included as well as descriptions of both new and historic materials' finish, color, and other information appropriate to a detail drawing (such as the exact location of the detail within the project).


PHOTOGRAPHIC REQUIREMENTS:


All prints must be identified on the back with the date, name of the undertaking, the photographer, and detail reference which locates the view of the picture within the overall project. Where photographs have previously been provided as part of the SHPO review submittal, there is normally no need to duplicate such photographs for submittal with the work plan. Also, undertakings which propose to remove and replace a historic component (such as a window) with new work, or which propose to overlay a historic construction with a nonhistoric one (such as the installation of new wood siding over historic wood siding), shall provide sufficient photographic documentation to depict, in clear detail, the particular construction problems to be remedied by the undertaking.


CONTRACT SPECIFICATION REQUIREMENTS:


The conditions to the contract should describe the general scope of work as subject to historic preservation considerations and the Secretary of the Interior's Standards for Rehabilitation. Each specification division, or set of work items, should specify the acceptable qualities of job materials. Also, the exact methods of execution should be addressed for each work item.
