Pulling a Project Together: Aggregation and Abstraction(?) 

 

 

UNIFORMAT II (UII) Classifications are being developed as individual, discrete, classifications of specific constructed entities.

This is deliberate as it is intended that each discrete classification be a stand-alone working tool (we’ll use the term module) that can, where necessary, be used in conjunction other UII classifications to meet the specific needs of any  project or program of work. They will work individually or as a package.

It should always be borne in mind that the concept of ‘functional elements’ was developed  for the improved estimation of construction when little of the project is known, and thus setting a basis for continuous cost control in a milieu of ever increasing detail as the design and working documents are developed.

 

While it may seem that the more detail (i.e. elements) is included in a classification the more useful it becomes, the opposite is true. The UII Guidelines paragraph 6.1 Element – Choice, Selection, and Desirable Attribute Rules (available to members of ASTM’s sub-committee E06.81 Building Economics, but soon to be abridged and added to this website) are specific when referring to the need for elements to be quantifiable “at all stages of development” and this includes the initial planning stage when no design detail is available, or yet contemplated, or approved. By being quantifiable at this planning stage the application of cost modelling techniques is aided and the results substantially improved. This is a form of Parametric Estimating that is routinely employed  to great effect in other industries.

The improvement possibilities in early estimation through using UII, will become invaluable to experienced practitioners, as it facilitates the examination of a variety of  options and the setting of realistic budgets prior to gaining the all-important client internal project funding, and other approvals. This is almost always prior to the implementation phase, wherein the design work and eventual construction is initiated and prgressed. This improved advance planning is achieved with a minimal additional expenditure of time and resources, as the results of earlier elemental construction analyses are ‘fed-forward’ into the new cost plan.

It is an unfortunate truth that the most important client decisions are made, and critical approvals are required, when the least information about a proposed scheme is known or available. UII elemental techniques help address this problem by providing more analytical, logical, and adjustable/revisable initial estimates than the traditional single rate or other ‘rule-of-thumb’ (heuristic) techniques in common use.
