Mikabei 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. Appendix X1 presents a more detailed suggested Level 4 classification of sub-elements. If the design as described in the PPD is within project scope and budget, the designers can proceed from the Schematic S to the Design Development Phase with the assurance that most major outstanding issues have ast, resolved or identified, the building design management team clearly understands the scope of work, and the client has signed off on the PPD. Some of these benefits include the following:.

Digar At the Schematic Phase, preliminary project descriptions PPD based on a standardized elemental classification framework that is consistent from project to project. In practice, the elemental format could also be used for this phase by the addition of more aztm design information to the description of each element, thus improving the building design management process.

Project managers face two major problems during the design phase that have a significant impact on the building design management team performance:. As a result, fewer major changes are likely to occur during the Design Development Phase, and the design schedule likely accelerated. 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 astn the resulting benefits for all participants.

Preliminary Project Descriptions and Outline Specifications. E estimates are linked to a PPD with a common classification at the outset of a project, further facilitating design cost analysis.

If the design as described in the PPD is within project scope and budget, the designers can proceed from the Schematic Phase to the Design Development Phase w the assurance that most major outstanding issues have been resolved or identified, the building design management team clearly understands the scope of work, and the client has signed off on the PPD.

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. The classification was the direct responsibility of Subcommittee E Appendix X1 presents a more detailed suggested Level 4 classification of sub-elements. Changes in the project team, i. With the elemental approach, the description, quantity and cost of the Exterior Wall B would aatm identified separately, thus greatly facilitating cost analysis.

ASTM E The project manager uses these to control project cost, time, and quality, and to set design-to-cost targets. Personal Publications Robert P. 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.

Cost overages are identified earlier than usual, allowing more time for corrective action to be taken without delaying the design schedule. It also enhances reporting at all stages in construction—from feasibility and planning through the preparation of working documents, construction, maintenance, rehabilitation, and disposal.

Means Square Foot Estimating. Link to Active This link asgm always route to the current Active version of the standard. Each design discipline is obliged to think through the project during the Schematic Phase and asgm tentative baseline solutions as well as alternatives for the concept and building systems that meet design program requirements. The elemental PPD adtm as a checklist for everyone that reviews and comments on the project. Link to Active This link will always route to the current Active version of the standard.

National Institute of Standards and Technology. 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. 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.

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. Presenting axtm 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.

Linking the formats at this phase is beneficial for the design team and the construction team that may already be on board. The classification is the common thread linking activities and participants in a building project from initial planning through operations, maintenance, and disposal.

Redesigning can be minimized, adding to the profitability for designers, and creating a good environment that encourages teamwork. ASTM E — 09 aetm 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 asrm.

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.

Charette, Robert, Brian Bowen. Charette, Robert and Anik Shooner Elements, as defined here, are major components common to most buildings.

This is possible because baseline systems have been well defined and estimated in the Schematic Design Phase and changes can still be made to lower the project life cycle cost without incurring major design costs. As a result, the architect is in a position to initiate project coordination earlier.

It is also unsuitable for process applications or for preparing trade estimates. Related Posts.

The project manager uses these to control project cost, time, and quality, and to set design-to-cost targets. Also, use the elemental cost data to expedite the development of cost models for building systems.
