LEAN Construction and OPEN Standard Data


LEAN CONSTRUCTION 101  – Common Terms, Definitions, and Data Formats

Standard classification of facility and other physical infrastructure elements is a requirement for LEAN Renovation, Repair, Maintenance, & New Construction Delivery.

Efficient, early, and ongoing communication from concept through a structures complete life-cycle is impossible without common and OPEN data.

Did you know that the original UNIFORMAT was developed jointly by  General Services Administration (GSA) and the American Institute of Architects (AIA) in 1972 for estimating and design cost analysis?

UNIFORMAT II, issued in 1993 and updated since, was developed by a larger group including  AACE,  CSI, GSA,  Tri-Services, RS Means Company, CIQS and a host of volunteers.

UNIFORMAT II is a classification of building elements per ASTM standard (i.e. E1557). Elements  are the  “major components, common to most buildings, that perform a given function, regardless of the design specification, construction method, or materials used.” Elements are also a logical component of a Work Breakdown Structure (WBS).

While UNIFORMAT II classifies common building elements, MASTERFORMAT is used to define the detailed  unit  line items  common to most buildings/structures.  While these are two distinct classifications systems, mapping information between them is also a requirement for efficient design, repair, renovation, maintenance, construction, costing, and overall life-cycle/total cost of ownership management.

Both UNIFORMAT II and MASTERFORMAT provide a common and OPEN data architectures to support collaborative LEAN construction delivery methods such as Integrated Project Delivery – IPD, and Job Order Contracting – JOC.  They enable a common “language” to support all phased of life-cycle management from concept through disposal.  The afforded transparency drives shared knowledge, and common agreement throughout conceptualization, scope of work creation, procurement, project execution, project sign-off/acceptance, and information “hand-off”, as well as a living repository of current information.

UNIFORMAT II and MASTERFORMAT classifications are hierarchical data frameworks that allow for multiple levels of aggregation and viewing of design, cost, workflow, auditing, information reuses, and other related practices.  As MASTERFORMAT is a “low level” more granular classification system, is has a one-to-many relation ship wit UNIFORMAT.
