Elemental Preliminary Project Description (PPD) Key Application Of UNIFORMAT II

Attention: open in a new window. PDFPrintE-mail

The elemental Preliminary Project Description (PPD) is based on the ASTM UNIFORMAT II Standard E1557. It offers a common point of agreement on specifications for all project stakeholders.

During the Schematic Design stage, consultants prepare concept drawings and a description (specification) of building systems proposed by each discipline. These documents must be approved by the client and other stakeholders before proceeding with the Design Development stage.

 

The FF/180 Practice of the Construction Specifications Institute (CSI) has recommended the preparation of a PPD based on UNIFORMAT type elements at the schematic design stage to communicate in a clear, concise manner the scope and relationship of major building systems and to expedite approval.

For an example of a PPD, see pages 15-22 of the NIST 6389 Publication.

About UNIFORMAT II

The ASTM E1557 "Standard Classification for Building Elements and Related Sitework - UNIFORMAT II" provides a common structure linking the building program, specifications, and estimates.

Its integration in the design process results in improved communications and coordination among all project participants, an accelerated design, and significantly increased productivity.

The classification provides the Project Manager with an essential tool to control project scope, cost, time and quality.
