4.5 Execution

A. Woodworking - General

1. Quality Standards - AWI Quality Standards are by reference made part of this Specification. Unless otherwise clearly detailed or specified in individual task orders, all cabinetry shall be fabricated to conform to AWI Quality Standards, Section 400, for custom grade material and workmanship.

2. Cabinetry - All casework shall be plant assembled. Cases too large for access into the exhibit area shall be made in detachable sections with provisions for assembly inside the exhibit space.

a. Fabrication Methods - All faceplates, panel ends, and doors shall be of mortise and tenon or doweled fabrication, glued under pressure, with nails only furnishing the pressure. All nails shall be properly set for filling. Filled areas shall be sanded smooth to receive laminate, paint, or other specified finish. Edges of panels and signs shall be filled, sanded smooth, and finished or covered with material matching the panel face. Edges shall not be left unfinished unless otherwise specified on the drawings.

b. Shelving - Unless otherwise specified in individual task orders, any shelving used as part of the interior of cabinets shall be 3/4" Birch plywood. At a minimum, audiovisual equipment shelving shall have 12" square center portions of perforated metal to allow ventilation around equipment. The contractor shall be responsible for ensuring that each shelf is fabricated of material of sufficient strength for the piece of equipment for which it is intended.

3. Architectural Millwork - Fabricate and assemble units complete in the shop, insofar as their dimensions will permit for transportation and proper handling. All woodwork shall be shop finished and delivered to the installation site with protective covering. Use solid stock for frames, jambs, heads, stops, and edges.

Harpers Ferry Center

Provide ample screw, glue-and-bolt blocks, draw-bolts, tongues, grooves, splines, dowels, tenons, mortises, and other means of fastening to render the work substantial, rigid, and permanently secured in the proper position. Provide material to permit scribing to walls, floors, and related work. Provide sufficient allowance for shrinkage occurring after installation. Provide mitered corners at doorframes with hairline joints. Fit and adjust doors to achieve smooth and noiseless operation. Exposed fasteners are unacceptable without prior approval from the COR.

Sealed Case Environment - To ensure that artifact case vitrines are as airtight as possible, seal all seams which could allow air exchange with the air outside the artifact and silica gel chambers. Fabrication shall be in accordance with Attachment E, Summary of Exhibit Conservation Guidelines, "Case Details and Illustrations, Section 6, Case Air Seal."

2. Silica Gel Chambers - Chambers that house silica gel shall be fabricated to maximize exchange of air with the chamber containing the artifacts and minimize exchange of air outside of the case. The chamber shall provide a sealed, stable environment necessary to protect the artifact(s) in the case. Fabrication shall be in accordance with Attachment E, Summary of Exhibit Conservation Guidelines, "Case Details and Illustrations, Section 5, Environmental Control."

C. Finishes
