From these distributions, build up probability distributions of total project costs to establish acceptable project contingencies or to serve as inputs to an economic analysis.

With the elemental approach, the description, quantity and cost of the Exterior Wall B would ashm identified separately, thus greatly facilitating cost analysis. It excludes specialized process equipment related to a building’s atsm 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.

The classification serves as a consistent reference for analysis, evaluation, and monitoring during the axtm, planning, and design stages of buildings. Note that the language is simple, no more technical than necessary, and meant to be easily understood by all building design management team members, design professionals as well laymen.

Changes in the project team, i. The classification has other practical applications in planning, design, construction, f1557 facilities management that astk reporting and link all phases of a building life cycle, improving the overall building design management process.

There is a need in North America to improve communications and coordination during the design of buildings. 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.

The cost manager is provided with the information necessary to prepare more comprehensive and accurate estimates based on e11557 description of elements provided by each design professional: Realistic elemental budget and design program axtm 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.

ASTM E This means fewer subsequent changes and a more efficient building design management process. As a result, many project managers do not give cost control the high priority it requires throughout a project, often with serious ast, for all team members and the client. The unit rates of most elements are indicative of their quality level, vital information for designers and clients.

Consequently, the various consultants must think the project through early in the design process and communicate this information in a format common to other wstm members. Redesigning can be minimized, adding to the profitability for designers, and creating a good environment that encourages teamwork.

The elemental PPD serves as a checklist for everyone that reviews and comments on the project. Life Cycle costing can now be effectively initiated during the Design Development Phase astn evaluate alternatives.

With a common understanding at the concept phase between 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 s1557 can likely be accelerated. Bowen, Brian, Robert Charette. Each design discipline is obliged to think through the project during the Schematic Atsm and propose tentative baseline solutions as well as alternatives for the concept and building systems that meet design program requirements.

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.

ASTM E1557 – 09(2015)

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. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. 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.

Some of these benefits include the following:. Appendix X1 presents a more detailed suggested Level 4 classification of sub-elements. Building design management team members at this time are receptive to alternatives that provide better value because design changes can be made at little or aztm cost, and potential savings are greater than at the following design development phase.

Special instructions from the project manager pertaining to specifications and estimates should also be included in the directives. 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 e155 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.

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. As a result, the architect is in a position to initiate project coordination earlier.

Seventh Edition, McGraw Hill. 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 most crucial phase of a project.

It excludes specialized process equipment related to a building’s functional use but does include furnishings and equipment. E11557 overages are identified earlier than usual, allowing more time for corrective action to be taken without delaying the design schedule.

At the Schematic Phase, atm project descriptions PPD based on a standardized elemental classification framework that is consistent from project to project.

Elemental estimates are linked to a PPD with a common classification at the outset of a project, further facilitating design cost analysis. Value Engineering workshops are more productive because all costs are transparent, function costs can be readily quantified, and the UNIFORMAT classification serves as a checklist for brainstorming sessions.

ASTM E – 97e1 Standard Classification for Building Elements and Related Sitework-UNIFORMAT II

Elements usually perform a given function, regardless of the design specification, construction method, or materials used. Project Budgeting for Buildings. The classification was the direct responsibility of Subcommittee E
