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: Newton Centre, MA Tel.: The author is Robert P. Cart The cart is empty.

ASTM E1557 – 09(2015)

Information is also more easily understood by clients and others who do not have a technical background. Cost overages are identified earlier than usual, allowing more time for corrective action to be taken without delaying the design schedule. 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.

Elemental estimates are linked to a PPD with a common classification at the outset of a project, further facilitating design cost analysis. Note that the language is simple, no more technical than astn, and meant to be easily understood by all building design management team members, design professionals as well laymen.

The unit rates of most elements are indicative of their quality level, vital information for designers and clients. The project benefits from their expertise at a time when design decisions are qstm 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 final stages of design.

National Institute of Standards and Technology. In practice, the elemental format could also be used for e5157 phase by the addition of more asgm design information to the description of each element, thus improving the building design management process. Special instructions from the project manager pertaining to specifications and estimates should also be included in the directives. The project manager, client and user are presented with a clear and simple project description, element by element, at the Schematic Phase; they are ast a position to provide informed comments much earlier than usual on any changes that may be required.


Each discipline must think through the project as the Schematic Phase progresses, select baseline concepts and construction systems that are judged most appropriate, and propose alternatives.

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. 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.

He may be reached by telephone or fax at or by e-mail at This e-mail address is being protected from spambots.

Furthermore, it allows input, at the schematic phase, from: The article should be of interest to all stakeholders in a building project, i. As a result, the architect is in a position to initiate project coordination earlier. No other units of measurement are included in this standard. Omissions are more readily identified and items that are not related to design program requirements can be deleted.

To implement UNIFORMAT II effectively for building design management, written directives or guidelines must be issued to each team member; a briefing session for the team should be held prior to the start of design to ensure that everyone clearly understands the procedures to be followed and the resulting benefits for all participants. 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.

Charette, Robert and Anik Shooner Preliminary Project Descriptions and Outline Specifications. It also enhances reporting at all stages in construction—from feasibility and planning through the preparation of working documents, construction, maintenance, rehabilitation, and disposal.


It is also unsuitable for process applications or for preparing trade estimates. A standardized cost reporting format based on UNIFORMAT II, such as shown in Figure 4 – Building Elemental Cost Summaryhas the added advantage of facilitating the rapid reconciliation of estimates from different sources; this is because all design and inflation contingencies, and overhead and profit can be calculated in the same way, a rare occurrence when comparing design estimates in today’s context.

These can change as design progresses, but within the total budget established.

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 classification was the direct responsibility of Subcommittee E There is a need in North America to improve communications and coordination during the design of buildings. 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 disproportionate amount of design fees and without significant delays in the design schedule.

The partition density the ratio of the quantity of partitions per square foot GFA is 1. Simulation is one technique Practice E for developing probability distributions of building costs when evaluating the economic risk in undertaking a building project.

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.
