ASTM E1557 – 09(2015)

Some of these benefits include the following:. Having a manual or database in an elemental format helps you perform economic analysis early in the design stage e11557 at reasonable cost. Elemental estimates are linked to a PPD with a common classification at the outset of a astmm, further facilitating design cost analysis.

Special instructions from the project manager pertaining to specifications and estimates should also be included in the directives. Omissions are more readily identified and items that are not related to design program requirements can be deleted. Linking the formats at this phase is beneficial for the design team and the construction e1575 that may already be on board.

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

A standardized cost reporting format based on UNIFORMAT II, such as shown in Figure 4 – Building Elemental Cost Summaryhas the added advantage of f1557 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. Simulation is one technique Practice E for developing probability distributions of building costs when evaluating the economic risk in undertaking a building project.

Information is also more easily understood by clients and others who do not have a technical background. See Practice E for guidance as to what economic method to use. 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.

Building Design Management With ASTM E UNIFORMAT II

The project manager uses these to control project cost, time, and quality, and to set design-to-cost targets. Redesigning can be minimized, adding to the profitability for designers, and creating a good environment that encourages teamwork.

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. As a result, fewer major changes are likely to occur during the Design Development Phase, and the design schedule likely accelerated.

American Institute of Architects.

This allows an architect, for example, to reference an exterior wall assembly according to UNIFORMAT II element designations and build up a database of standard details structured according to the classification. Charette, Robert and Anik Shooner 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.

This approach provides the technical and cost information necessary to initiate life cycle costing, energy analysis, and value engineering studies during the initial phase of the design process, i. Elements, as defined here, are major components common to most buildings. Bowen, Brian, Robert Charette. 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 no cost, and potential savings are greater than at the following design development phase.

This prevents projects from going “sour” because of costly redesigns and delays due to cost overruns and scope creep that must be resolved early on in a project. 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.

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. Personal Publications Robert P. Life Cycle costing can now be effectively initiated during the Design Development Phase to evaluate alternatives. It is also unsuitable for process applications or for preparing trade estimates.

The elemental PPD serves as a checklist for everyone that reviews and comments on the project. 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.

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. The classification serves as a consistent reference for analysis, evaluation, and monitoring during the feasibility, planning, and design stages of buildings.

The project benefits 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 final stages of design. 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.

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. Preliminary Project Descriptions and Outline Specifications. Also, use the elemental cost data to expedite the development of cost models for building systems. Link to Active This link will always route to the current Active version of the standard. Appendix X1 presents a more detailed suggested Level 4 classification of sub-elements.

Newton Centre, MA Tel.: Elements usually perform a given function, regardless of the design specification, construction method, or materials used. The author is Robert P. Furthermore, it allows input, at the schematic phase, from: The project manager, client and user are presented with a clear and simple project description, element by element, at the Schematic Phase; they are in a position to provide informed comments much earlier than usual on any changes that may be required.

As a result, the architect is in a position to initiate project coordination earlier. Active view current version of standard. It excludes specialized process equipment related to a building’s functional use but does include furnishings and equipment.

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.
