Personal Publications Robert P. It is more comprehensive than the original, particularly with respect to the mechanical and sitework elements. 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.

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.

Building Design Management With ASTM E UNIFORMAT II

The unit rates of most elements are indicative of their quality level, vital information for designers and clients. The classification is the common thread linking activities and participants in a building project from initial planning through operations, maintenance, and disposal.

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 classification was the direct responsibility of Subcommittee E You need JavaScript enabled to view it.

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.

Newton Centre, MA Tel.: The article should be of interest to all stakeholders in a building project, i. Changes in the project team, i. Cost overages are identified earlier than usual, allowing more time for corrective action to be taken without delaying the design schedule. Appendix X1 presents a more detailed suggested Level 4 classification of sub-elements. With the elemental approach, the description, quantity and cost of the Exterior Wall B would be identified separately, thus greatly facilitating cost analysis.

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. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the 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, thus improving the building design management process.


These can change as design progresses, but within the total budget established. As a result, fewer major changes are likely to occur during the Design Development Phase, and the design schedule likely accelerated.

Linking the formats at this phase is beneficial for the design team and the construction team that may already be on board. Quality management programs such as ISO require documentation at each stage of a process. 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.

Furthermore, it allows input, at the schematic phase, from: There is a need in North America to improve communications and coordination during the design of buildings. Also, use the elemental cost data to expedite the development of cost models for building systems. 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.

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.

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

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.


No other units of measurement are included in this standard. Project Budgeting for Buildings. Lack of design and cost information is always one of the major obstacles to the effective introduction of life cycle costing, energy analysis, and value engineering early in the design process, a problem that can be resolved with UNIFORMAT II. The elemental PPD serves as a checklist for everyone that reviews and comments on the project. Elemental estimates are linked to a PPD with a common classification at the outset of a project, further facilitating design cost analysis.

ASTM E1557 – 09(2015)

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. 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 asmt.

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. This means fewer subsequent changes and a awtm efficient building design management process. It also enhances reporting at all stages in construction-from feasibility and planning through the preparation of working documents, construction, maintenance, rehabilitation, and disposal.

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

Link to Active This link will always route to the current Active version of the standard. 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.

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.
