Frequent Scenario Information Phase Data Collection
• Design data – inadequate variable,dispersed
• Cost data - many unknowns,high contingencies
• Design and cost data formats – inconsistent
• Energy data – unavailable early in design
• Timing of VE workshops – delays, lower ROI
A DESIGN MANAGEMENT PROBLEM !!!REDUCES VE TEAM PERFORMANCE & ROI

A Paradigm to Increase VE Team Performance • Initial Workshop at the Schematic/Concept Phase
– Greater potential savings,higher ROI
• A Consistant Elemental Data Reporting Format– ASTM UNIFORMAT II Classification E1557 (function based)
• UNIFORMAT II Preliminary Project Descriptions (PPD)– Per CSI Practice FF/180 to define baseline in all disciplines
• UNIFORMAT II Elemental Estimate– With analytic parameters for design cost analysis
• Baseline Energy Analysis Simulation (DOE 2)– To evaluate energy VEP, actual vs targeted energy budget

Definition of “Element”(Assembly,System)
• Classic DefinitionA major component, common to most buildings,that performs a given function, regardless of the design specifications, construction method ormaterials used e.g. B10 Superstructure
• In PracticeA component of a Work Breakdown Structure (WBS)e.g. A2010 Basement Excavation

Typical Analytic Parameters (200) FOR DESIGN COST ANALYSIS AND COST PLANNING
• Building Cost $/SF Including All Mark-ups– sitework costs excluded
• Element UOM, Unit Costs, Quantities,% Total– e.g. D3030 Cooling Generation $/TR, %
• Element Costs/SF GFA– e.g. C3030 Ceiling Finishes - cost in $/SF GFA
• Ratios of Element Quantities/SF GFA– e.g. C1010 Partitions – ratio SF/GFA

Benefits of UNIFORMAT II SchematicPhase PPD and Estimates
• All Disciplines Conceptualize Baseline Systems Early – Yardstick to compare design alternatives proposed
• All Systems Described in a Preliminary Project Description (PPD)– A communications hub linking all stakeholders, coordination improved
• Elemental Estimates Based on System Descriptions by Designers– Fewer unknowns, reduced allowances and contingencies, more accuracy
• Project Manager Can Introduce Project Optimization Tools– OM&R budgets, LCC, cost risk analysis, risk management
• Accelerated Schematic Design Approval – Due to range of VE alternatives considered, comprehensive submittals to
client
WITH DATA AVAILABLE - VE TEAM EFFICIENCY INCREASED

Other UNIFORMAT II APPLICATIONS
• Program Technical Requirements – DND, SIQ
• Performance Specifications – USN
• Elemental Preliminary Schedules – R.S Means
• Building Condition Evaluation – Hydro Quebec
• Capital Replacement Budgeting – Laval University
• Historic Capital Cost Data Bases – such as RICS
• M&R Cost Data - R.S. Means 2004
