Closet & Utility Shelving Section 600

General Information 600-G-1 Scope Includes: This section covers closet and utility shelving and its construction. Excludes: Factory assembled units or components within assembled cabinets (Section 400 Cabinets or 1600 Modular Cabinets). Unless required by details and/or woodwork specifications, the woodworker shall not install shelving or furnish common blocking (within a wall or ceiling) for the support of shelving.

600-G-3 Customary Practice Closet and utility shelving customarily utilizes the walls of the building to support cleating for the shelving. Details or specifications should indicate the type of supports desired for shelf spans. The wide variety of storage and loading requirements results in the following standards being necessarily vague. Analysis of weight requirements is an important factor. Involve your woodworker early in the project to coordinate the arrangement of shelving and/or hardware. Experience shows fixed shelf systems are inherently capable of supporting greater weight than similar adjustable systems. Even the addition of an inconspicuous intermediate support will often increase the support at no expense to the design concept of the system.

600-G-2 Specification Requirements GRADE MUST BE SPECIFIED

600

AWI Architectural Woodwork Standards provide for three Grades: Premium, Custom, and Economy.

Premium Grade The Grade specified when the highest degree of control over the quality of workmanship, materials, installation and execution of the design intent is required. Usually reserved for special projects, or feature areas within a project.

Custom Grade The Grade specified for most conventional architectural woodwork. This grade provides a well-defined degree of control over the quality of workmanship, materials and installation of a project. The vast majority of all work produced is Custom Grade.

Economy Grade The Grade that defines the minimum expectation of quality, workmanship, materials, and installation within the scope of AWI Standards.

Prevailing Grade When the AWI Quality Standards are referenced as a part of the contract documents and no Grade is specified for paneling, AWI Custom Grade standards will prevail.

NOTE: It is the responsibility of the design professional to engineer the shelf size, thickness, and support systems to meet the load-carrying needs of the project. The following shelf deflection information may assist in that process. The deflection of 1/4" is used for illustration purposes. AWI sets no minimum or maximum allowable deflection. The key factor in the equation is the Modulus of Elasticity (E). Tables of E-values for solid wood are published by the U.S. Department of Agriculture in The Wood Handbook - Wood as an Engineering Material, Agriculture Handbook 72. Tables of E-values for many panel product core materials are published by the National Particleboard Association.

Closet & Utility Shelving Section 600

Shelf Deflection Information The Department of Wood Science in the Division of Forestry at West Virginia University conducted a study for the Architectural Woodwork Institute regarding the deflection of wood shelving materials under various amount of stress. The following table represents their findings with the various products tested. The table shows total uniformly distributed load requirements necessary to cause deflection of 1/4" in shelves 8 and 12" wide with spans (i.e., unfixed, supported at each end) of 30", 36", 42", and 48". Load required to deflect shelves more or less than 1/4" may be estimated by direct proportion. For example, the uniformly distributed load required to cause a deflection of 1/8" is one-half that of the value in the table. For widths different than 8 or 12" (the values used in the table), load required to cause a 1/4" deflection may also be determined by direct proportion. A 6" wide shelf, for example, will deflect twice as much as a 12" wide shelf under the same load.

The following equation shows how deflection is related to shelf dimensions, width, thickness, span, load per inch of span, and Evalue, a material property which measures stiffness or resistance to deflection. The higher the E-value, the less the deflection. When a shelf is made with several materials, each with its own E-value, a composite E-value must be determined.

To compute deflection: 4 D= 0.1563wl Ebh3 In which the values are: D = deflection (in inches) w = load per lineal inch of span l = span (length) E = modulus of elasticity b = base (width) h = depth (thickness)

600-S-10 Selection for Grain and Color Plant Assemblies For Transparent finish, adjacent members shall … • Premium Grade: … be well matched for grain and color. • Custom Grade: … be compatible for color. • Economy Grade: … not be selected. Visible finger joints not permitted in Premium and Custom Grades. No selection for grain or color is required for Opaque finish in any Grade. Field Assemblies Selection of adjacent members for compatibility is the responsibility of the installation contractor.

Tests 600-T-1 Tests for Smoothness of Exposed Surfaces KCPI (Knife Cuts Per Inch) can be determined by holding the surfaced board at an angle to a strong light source and counting the visible ridges per inch, usually perpendicular to the profile. SANDING can best be checked by sanding a sample piece of the same species with the required grit of abrasive. Observation with a hand lens of the prepared sample and the material in question will offer a comparison of the scratch marks of the abrasive grit. Reasonable assessment of the performance of the finished product will be weighed against absolute compliance with the standard.

600-T-2 Tightness and Flushness of Plant Assembled Joints Joint tightness and/or flushness will meet the standard when tested with a feeler gauge at the points indicated in the illustration. Joint length will be measured with a ruler with a minimum division of 1/16" and calculations made accordingly. Reasonable assessment of the performance of the finished product will be weighed against absolute compliance with the standard.

Design Ideas 600-D Freedom of Expression This section is a sampling of design ideas. It makes no pretense of being complete. It’s here for the reader to use as a starting place. The exercise of personal creativity is the essence of fine architectural woodworking. Custom-designed woodwork gives you complete freedom of expression. • Design Flexibility: The use of custom designed woodwork in a building allows the design professional freedom of expression while meeting the functional needs of the client. A custom designed building is enhanced by the use of custom designed woodwork. • Cost Effective: Custom woodwork does compete favorably with mass produced millwork, and offers practically limitless variations of design and material. Most woodwork lasts the life of the building—quality counts. • Complete Adaptability: By using custom woodwork the architect or designer can readily conceal plumbing, electrical and other mechanical equipment without compromising the design criteria. • No Restrictions: Custom architectural woodwork permits complete freedom of selection of any of the numerous hardwoods and softwoods available for transparent or opaque finish. Other unique materials available from woodwork manufacturers require no further finishing at all, such as plastic laminates and decorative overlays. These materials can be fashioned into a wide variety of profiles, sizes, and configurations. The owner and design professional have the best of both worlds—high quality and freedom of choice. • Dimensional Flexibility: Since custom woodwork is normally produced by a specialty architectural woodwork firm, dimensions can easily be changed prior to actual fabrication if required by job conditions. Special situations such as designing for the handicapped can readily be accommodated by the custom architectural woodwork manufacturer. • Quality Assurance: Adherence to the AWI Quality Standards will help guarantee the design professional of a quality product at a competitive price. Use of a qualified AWI member firm will help insure the woodworker’s understanding of the quality level required. Specifying that the woodwork be certified under the AWI National Quality Certification Program is the best guarantee of compliance with the Quality Standards and the project specifications.
