A. Drawings and general provisions of Contract, including General and Supplementary Conditions and other Division 1 Specification Sections, apply to this Section.

1.02 PROJECT

A. Project Name: Timberline Lodge Potable Plumbing Replacement.

B. The Project consists of the replacement of the all-existing polypropylene (PP-R) and specialty pipes with copper piping and specialties as specified in Division 22. All previously installed PP-R piping will be replaced.

C. Attached PP-R piping construction drawings of 2010 show the existing PP-R piping routes and sizes. Prior to 2010, all domestic water piping were copper. Current scope of work is to demo the 2010 PP-R piping and reinstall copper piping. New copper piping routes and sizes will be the sane as PP-R piping routes and sizes as shown in attached 2010 construction drawings.

D. Non-PP-R piping such as PEX piping in guest rooms and public rest rooms will remain.

E. Piping hangers and support will meet the following requirements:

1. ASCE 7-10, Minimum Design Loads for Buildings and Other Structures.

2. Hanger spacing installation and attachment to meet all manufacturers requirements and Code requirements.

3. Terminology: As defined in MSS SP-90 "Guidelines on Terminology for Pipe Hangers and Supports".

4. Per SMACNA's requirements.

5. Engineering Responsibility: Design and preparation of Shop Drawings and calculations for each multiple pipe support, trapeze, equipment hangers/supports, and seismic restraint calculations performed by a professional structural engineer.

F. Plumbing work will include the integration of existing recirculation pumps with associated piping and electrical items for a hot water return loop from the West Wing and East Wing attics to the Boiler Room.

G. Project work will also include the demolition and construction of wall and ceiling framing and finishes for removal of the existing piping and installation/concealment of replacement piping.

TIMBERLINE LODGE HISTORIC BUILDING PRESERVATION PLAN EXECUTIVE SUMMARY

The Mt. Hood National Forest is the administrator of Timberline Lodge, a National Historic Landmark. The Forest has utilized the best knowledge and experience available from historians and historical architects as well as technical guidance from the National Park Service, the Oregon State Historic Preservation Office, and the General Services Administration to develop historic preservation strategies for a Historic Building Preservation Plan (HBPP) for the Lodge. The intent of the Forest Service was to create an instrument which documents the structure, but more importantly, is a living document that will provide managers credible alternatives for routine maintenance, rehabilitation, restoration, and replacement of historic fabric throughout the building;

i.e., treatments for all elements making up the structure and the numerous features within it. The HBPP is a document that is useable, practical, and which enables administrators to fulfill historic preservation objectives.

Rather than a static interpretive piece, or a museum, or visitor center, the Lodge is a working hotel.

Hotel managers and Forest Service administrators must be adaptable and prepared to evolve with changing public demands, increasing wear, new codes, and new laws.

PLAN METHODOLOGY

The HBPP has been written in three general phases. Each phase provides the basis for the next. The first phase identifies the historic building and creates an historical frame of reference. The second phase identifies physical zones of the structure and assigns each zone an appropriate preservation strategy. The third phase identifies significant architectural elements within each zone, assigns each element a specific treatment strategy, and provides approved treatment tactics for preservation, maintenance, repair, and replacement.

Phase I

For the first phase the…
