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. Project managers face two major problems during the design phase that have a significant impact on the building design management team performance:.
ASTM E – 97e1 Standard Classification for Building Elements and Related Sitework-UNIFORMAT II
It also enhances reporting at all stages in construction—from feasibility and planning through the preparation of working documents, construction, maintenance, rehabilitation, and disposal.
These can change as design progresses, but within the total budget established. With the elemental approach, the description, quantity and cost of the Exterior Wall B would be identified separately, thus greatly facilitating cost analysis. 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.
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 f1557 in the design process, a problem that can be resolved with UNIFORMAT II.
Building Design Management With ASTM E UNIFORMAT II
American Institute of Architects. Elements are traditionally defined as asttm components, common to most buildings, that perform a given function, regardless of the design specification, construction method, or materials used.
Also, use the elemental cost data to expedite the development of cost models for building systems. Significantly improved project team communications, coordination and productivity as a result of linking the PPD and the estimate within e11557 common framework at the Schematic Design Phase, the most crucial phase of a project.
Personal Publications Robert P. Furthermore, it allows input, at the schematic phase, from: Each design discipline is obliged to think through the project during the Schematic Phase and propose tentative baseline solutions as well as alternatives for the concept and building systems that meet design program requirements. The classification serves as a consistent reference for analysis, evaluation, and monitoring during the feasibility, planning, and design stages of buildings.
ast, Pushing the decision making up front for the selection of building systems also reduces the probability of major changes as design progresses, changes that are time consuming and costly to everyone concerned. As a result of improved team communications and coordination, the project manager can have more time to address other important issues, and manage the project to a successful completion with less effort than normally required.
This approach provides the technical and cost information asfm to initiate life cycle costing, energy analysis, and value engineering studies during the initial phase of the design process, i. Changes in the project team, i.
Doing so results in economic benefits to the construction industry as a whole. Link to Active This link will always route to the current Active version of the standard. 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.
Charette, Robert and Anik Shooner Consequently, the various consultants must think the project through early in the design process and asmt this information in a format common to other team members. In practice, the elemental format could w1557 be asgm for this phase by the addition of more detailed design information to the description of each element, thus improving the building design management process.
Active view current version of standard. The classification was the direct responsibility of Subcommittee E 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.
The article should be of interest to all stakeholders in a building project, i. 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.
Life Cycle costing can now be effectively initiated during the Design Development Phase to evaluate alternatives. It excludes specialized process equipment related to a building’s functional use but does include furnishings and equipment. Elements, as defined here, are major components common to most buildings.
Charette, Robert, Brian Bowen. Elemental estimates are linked to a PPD with a common classification at the outset of a project, further facilitating design cost analysis. He may be reached by telephone or fax at or by e-mail at This e-mail address is being protected from spambots.

There is a need in North America to improve communications and coordination during the design of buildings. 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.
Elements usually perform a given function, regardless of the asfm specification, construction method, or materials used.
Bowen, Brian, Robert Charette. Quality management programs such as ISO require documentation at each stage of a 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.
Estimating formats that differ from project to project, require too much time to comprehend, do not support design cost analysis, and that cannot easily be monitored from one design phase to another no audit trail.
