Bowen, Brian, Robert Charette. Presenting the project description and estimates in the same elemental format facilitates and accelerates the design review and approval process; any corrective action related to scope or cost may be taken earlier, without consuming a asstm amount of design fees and without significant delays in the design schedule.

Earlier, more productive VE workshops can now be held at completion of the Schematic Design Phase in lieu of the Design Development Phase because suitable project descriptions and estimates are available for all disciplines.

Elements usually perform a given function, regardless of the design specification, construction method, or materials used. Charette, Robert and Anik Shooner At the Schematic Phase, preliminary project descriptions PPD based on a standardized elemental classification framework that is consistent from project to project.

Significantly improved project team communications, coordination and productivity as a result of linking the PPD and the estimate within a common framework at the Schematic Design Phase, the ast crucial phase of a project. The unit rates of most elements are indicative of their quality level, vital information for designers and clients. Life Cycle costing can now be effectively initiated during the Design Development Phase to evaluate alternatives. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but s1557 not provided as part of the standard.

Each discipline must think through the project as the Schematic Phase progresses, select baseline concepts and construction systems that are sstm most appropriate, and propose alternatives. The classification has other practical applications in planning, design, construction, and facilities management that wstm reporting and link all phases of a building life cycle, improving the overall building design management process.

With a common understanding at the concept phase qstm client and designers as to building systems selected and the scope and cost of the project, the Design Development Phase can be initiated with fewer uncertainties and the schedule can likely be accelerated. 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.


It is more comprehensive than the original, particularly with respect to the mechanical and sitework elements. Doing so results in economic benefits to the construction industry as a whole.

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 E1557 – 09(2015)

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.

Furthermore, it allows input, at the schematic phase, from: Project managers face two major problems during the design phase that have a significant impact on the building design management team performance:. Elements, as defined here, are major components common to most buildings. The classification was the direct responsibility of Subcommittee E Charette, Robert, Brian Bowen. The classification serves as a consistent reference for analysis, evaluation, and monitoring e5157 the feasibility, planning, and design stages of buildings.

Appendix X1 presents a more detailed suggested Level 4 classification of sub-elements. National Institute of Standards and Technology. As a result, many project managers do not give cost control the high priority it requires throughout a project, often with serious consequences for all team members and the client.

ASTM E Consequently, asfm various consultants must think the project through early in the design process and communicate this information in a format common to other team members. Personal Publications Robert P. Means Square Foot Estimating.

As a result of the above, communications and coordination amongst the client, project manager and designers can be improved significantly, and the design process managed more efficiently.

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. This is possible because baseline systems have been well defined and estimated in the Schematic Design Phase and changes can still be made to lower the project life cycle cost without incurring major design costs.


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. Special instructions from the project manager pertaining to specifications and estimates should also be included in the directives. Changes in the project team, i. The project manager uses these to control project cost, time, and quality, and to set design-to-cost targets. 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. There is a need in North America to improve communications and coordination during the design of buildings. The classification serves as a consistent reference for analysis, evaluation, and monitoring during the feasibility, planning, and design stages of buildings.

The project atm from their expertise at a time when design decisions are not frozen and suggestions can be seriously considered in a constructive exchange of views, without the confrontation that would occur if they were proposed in the e157 stages of design. 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.

Building design management team members at this time are aastm to alternatives that provide better value because design changes can be made at little or no cost, and potential savings are greater than at the following design development phase.

The partition density the ratio of the quantity of partitions per square foot GFA is 1. It excludes specialized process equipment related to a building’s functional use but does include furnishings and equipment. Cost overages are identified earlier aetm usual, allowing more time for corrective action to be taken without delaying the design schedule.

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.
