It excludes specialized process equipment related to a building’s functional use but does include furnishings and equipment.

Information is also more easily understood by clients and others who do not have a technical background. Life Cycle costing can now be astk initiated during the Design Development Phase e1557 evaluate alternatives. The classification was the direct responsibility of Subcommittee E 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.

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 atm available for all disciplines.

The classification serves as e5157 consistent reference for analysis, evaluation, and monitoring during the feasibility, planning, and design stages of buildings. 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.

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. Furthermore, it allows input, at the schematic phase, from: Simulation is one technique Practice E for developing probability distributions of building costs when evaluating the economic risk in undertaking a building project.

ASTM E1557 – 09(2015)

Elements usually perform a given function, regardless of the design specification, construction method, or materials used. 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. Elements, as defined here, are major components common to most 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.

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. 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. Linking the formats at this phase is beneficial for the design team and the construction team that may already be on board.

Project managers face two major problems during the design phase that have a significant impact on the building design management team performance:. Elements usually perform a given function, regardless of the design specification, construction method, or materials used. Cart The cart is empty. It is more comprehensive than the original, particularly with respect to the mechanical and sitework elements.


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. ASTM E There is a need in North America to improve communications and coordination during the design of buildings. Omissions are more readily identified and items that are not related to design program requirements can be deleted.

Elemental estimates are linked to a PPD with a common classification at the outset of a project, further facilitating design cost analysis.

Link to Active This link will always route to the current Active version of the standard. 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 also enhances reporting at all stages in construction—from feasibility and planning through the preparation of working documents, construction, maintenance, rehabilitation, and disposal.

Building Design Management With ASTM E 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 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.

Some of these benefits include the following:. American Institute of Architects. It is also unsuitable for process applications or for preparing trade estimates. Each discipline must think through the project as the Schematic Phase progresses, select baseline concepts and construction systems that are judged qstm appropriate, and propose alternatives.

Charette, Robert, Brian Bowen. Means Square Foot Estimating. Link astn Active This link will always route to the current Active version of the standard.

E15557 the project description and estimates in the same elemental format facilitates and e15557 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.

Standard Classification for Building Elements and Related Sitework-UNIFORMAT II

Also, use the elemental cost data to expedite the development of cost models for building systems. Changes in the project team, i. As a result, the architect is in a position to initiate project coordination earlier.

These can change as design progresses, but within the total budget established. Charette, Robert and Anik Shooner See Practice E for guidance as to what economic method to use. At the Schematic Phase, preliminary project descriptions PPD based on a standardized elemental classification framework that is consistent from project to project.

The elemental PPD serves as a checklist for everyone that reviews and comments on the project. Newton Centre, MA Tel.: Appendix X1 presents a e15577 detailed suggested Level 4 classification of sub-elements.

The classification is the common thread linking activities and participants in a building project from initial planning through operations, maintenance, and disposal.
