Quality management programs such as ISO require documentation at each stage of a process. Seventh Edition, McGraw Hill. This means fewer subsequent changes and a more efficient building design management process.
Elemental design estimates with a standardized classification system that is consistent from phase to phase and project to project, that is more accurate because of the information provided in the PPD, easily understood by all team members, and suitable for design cost analysis. Preliminary Project Descriptions and Outline Specifications. Life Cycle costing can now be effectively initiated during the Design Development Phase to evaluate alternatives. These can change as design progresses, but within the total budget established.
The classification has other practical applications in planning, design, construction, and facilities management that standardize reporting and link all phases of a building life cycle, improving the overall building design management process. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Elements usually perform a given function, regardless of the design specification, construction method, or materials used. At the Schematic Phase, preliminary project descriptions PPD based on a standardized elemental classification framework that is consistent from project to project. The cost manager is provided with the information necessary to prepare more comprehensive and accurate estimates based on a description of elements provided by each design professional: The cost manager can prepare more detailed Schematic Phase estimates for all disciplines with a higher degree of accuracy than usual, based on the PPD provided by each consultant; if the project is within budget, there should be no major concern as to the final project cost other than for major scope changes initiated by the client and for which additional funding should be provided.
The elemental PPD serves as a checklist for everyone that reviews and comments on the project. It also enhances reporting at all stages in construction-from feasibility and planning through the preparation of working documents, construction, maintenance, rehabilitation, and disposal.

The unit rates of most elements are indicative of their quality level, vital information for designers and clients.
Historical Version s – view previous versions of standard.
Means Square Foot Estimating. Cart The cart is empty. Pushing the decision making up front for the selection of building systems also reduces the probability of major aztm as design progresses, changes that are time consuming and costly to everyone concerned.
Lack of design and cost information is always one of the major obstacles to the effective introduction of life cycle costing, energy analysis, and value engineering early in the design process, a problem that can be resolved with UNIFORMAT II. Active view current version of standard. National Institute of Standards and Technology. In practice, the elemental format could also be used for this phase by the addition of more detailed design information to the description of each element, thus improving the building design management process.
Inadequate communications and coordination among project team members resulting in misunderstandings, delays, and lower productivity than anticipated. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
The author is Robert P. Bowen, Brian, Robert Charette.
Charette, Robert and Anik Shooner As a result of improved team communications and coordination, the project manager can r1557 more time to address other important issues, and manage the project to a successful completion with less effort than normally required. Elements are traditionally defined as “major components, common to most buildings, that perform a given function, regardless of the design specification, construction method, or materials used.
Note that the language is simple, no more technical than necessary, and meant to be easily understood by all building design management team e1557, design professionals as well laymen. Project managers face two major problems during the design phase that have a significant impact on the building design management team performance:. It excludes specialized process equipment related to a building’s functional use but does include furnishings and equipment.
It facilitates the description of the scope of the project for the client in a clear, concise, and logical sequence; it provides the basis for the preparation of more detailed elemental estimates during the early concept and preliminary design phases, and it enhances communications among designers and other building professionals by providing a clear statement of the designer’s intent.
ASTM UNIFORMAT II Standard
Doing so results in economic benefits to the construction industry as a whole. Consequently, the various consultants must think the project through early in the design process and communicate this information in a format common to other team members. American Institute of Architects. Realistic elemental budget and design program estimates can be prepared from historical and published elemental cost data, using cost modelling techniques outlined in the text “Project Budgeting for Buildings” that is listed in the UNIFORMAT references 9.
Some of these benefits include the following:. Appendix X1 presents a more detailed suggested Level 4 classification of sub-elements. Elements, as defined here, are major components common to most buildings. Elements, as defined here, are major components common to most buildings. It excludes specialized process equipment related to a building’s functional use but does include furnishings and equipment.
For example, in a conventional trade estimate, all components of an exterior wall such as the brick, vapor retarder, insulation and block back-up would be priced separately, distributed in their respective divisions, and their cost summarized with all other products, according to Divisionsusually with no indication as to their construction function, i.
It also enhances reporting at all stages in construction—from feasibility and planning through the preparation of working documents, construction, maintenance, rehabilitation, and disposal.
