Specifications and Project Manual Conference. Summer 2005 Session 1 - The Preliminary Project Description and UniFormat

Assumptions Well-prepared documents improve coordination, communication and productivity during all phases of the project. The type and purpose of written documents vary with each project phase.

Well-prepared documents improve coordination, communication and productivity during all phases of the project.

The type and purpose of written documents vary with each project phase.

Experience Gap Inexperienced assumptions. Paradox of over-drafting.

Inexperienced assumptions.

Paradox of over-drafting.

Bridging Gap Preliminary Project Description and UniFormat, when used together as a system, are great tools for bridging the gap for primarily 3 reasons: Flexible and expandable throughout the design and production process. Do not require any special skills to use. Edify as well as communicate design intent.

Flexible and expandable throughout the design and production process.

Do not require any special skills to use.

Edify as well as communicate design intent.

Preliminary Project Description Introduction Early basis for discussion of the proposed systems and assemblies. A communication tool to facilitate understanding of the project. Document that includes proposed design solutions and decisions made or to be made and serves as a master guide for the project from which all subsequent project documentation will flow.

Introduction

Early basis for discussion of the proposed systems and assemblies.

A communication tool to facilitate understanding of the project.

Document that includes proposed design solutions and decisions made or to be made and serves as a master guide for the project from which all subsequent project documentation will flow.

Preliminary Project Description Preparation. Design team required to think through the project and document decisions and design criteria in broad terms . Format allows changes to be made without disrupting the ongoing design process. Following schematic design, a PPD may be maintained and updated for use as an instrument of communication between project participants and as a source of information when developing outline specifications during design development.

Basic Organization .

UniFormat Classification System Numbers and Titles . Generic titles independent of design solution. Two rules of classification: Specialization . Level 1 categories listed by classes of information designated by a letter of the alphabet. Decomposition . Level 2 classes carry the letter of their parent category, plus a 2-digit number. Levels 3 and 4 are further developed by subdivision.

UniFormat Classification System Differences with MasterFormat . UniFormat Systems and assemblies having a determinable function. Organization of parts of completed construction based upon sequence of construction. Emphasizes the perspective of the user, owner and architect’s view of construction. MasterFormat “ Work Results” having specifiable characteristics. Organization of components based upon material, location, function, application and attribute. Emphasizes the perspective of the product manufacturer, supplier, specifier and contractor’s view of construction.
