ASTM UNIFORMAT II Standard
Life Cycle costing can now be effectively initiated during the Design Development Phase to evaluate f1557. 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: The classification was the direct responsibility xstm Subcommittee E Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
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. Cost overages are identified earlier than usual, allowing more time for corrective action to be taken without delaying the design schedule.
Historical Version s – view previous versions of standard. 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, asfm improving the building design management process. Bowen, S1557, Robert Charette.

These can change as design progresses, but within the adtm budget established.
ASTM E1557 – 09(2015)
Elements, as defined here, are major components common to most buildings. Simulation is one technique Practice E for developing probability distributions of building costs when evaluating the economic risk in undertaking a building project. 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.
As a result of improved team communications and coordination, the project manager can have more time to address other important issues, and manage the project to a successful completion with less effort than normally required. 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.
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.
Having a manual or database in an elemental format helps you perform economic analysis early in the design stage and at aztm cost. Doing so results in economic benefits to the construction industry as a whole. As a result, the architect is in a position to initiate project coordination earlier.
Charette, Robert, Brian Bowen. The project manager uses these to control project cost, time, and quality, and to set design-to-cost targets.
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. For example, in asmt 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.
Inadequate communications and coordination among project team members resulting in misunderstandings, delays, and lower productivity than anticipated.

Elements usually perform a given function, regardless of the design specification, construction method, or materials used. See Practice E for guidance as to what economic method to use. The elemental PPD serves as a checklist for everyone that reviews and comments on the project. Preliminary Project Descriptions and Outline Specifications.
No other units of measurement are included in this standard. The article should be of interest to all stakeholders in a building project, i. It also enhances reporting at all stages in construction-from feasibility and planning through the preparation of working documents, construction, maintenance, rehabilitation, and disposal.
Appendix X1 presents a more detailed suggested Level 4 classification of sub-elements.

This means fewer subsequent changes and a more efficient building design management process. This prevents projects from going “sour” because of costly redesigns and delays asrm to cost overruns and scope creep that must be resolved early on in a project.
