18R-97: Cost Estimate Classification System - Kenai Peninsula ...

Cost Estimate Classification System – As Applied in EngineeringProcurement, and Construction for the Process IndustriesESTIMATE INPUT CHECKLIST AND MATURITY MATRIX8 of 9February 2, 2005Figure 4 maps the extent and maturity of estimate input information (deliverables) against the fiveestimate classification levels. This is a checklist of basic deliverables found in common practice in theprocess industries. The maturity level is an approximation of the degree of completion of the deliverable.The degree of completion is indicated by the following letters.• None (blank): development of the deliverable has not begun.• Started (S): work on the deliverable has begun. Development is typically limited to sketches, roughoutlines, or similar levels of early completion.• Preliminary (P): work on the deliverable is advanced. Interim, cross-functional reviews have usuallybeen conducted. Development may be near completion except for final reviews and approvals.• Complete (C): the deliverable has been reviewed and approved as appropriate.ESTIMATE CLASSIFICATIONGeneral Project Data: CLASS 5 CLASS 4 CLASS 3 CLASS 2 CLASS 1Project Scope Description General Preliminary Defined Defined DefinedPlant Production/Facility Capacity Assumed Preliminary Defined Defined DefinedPlant Location General Approximate Specific Specific SpecificSoils & Hydrology None Preliminary Defined Defined DefinedIntegrated Project Plan None Preliminary Defined Defined DefinedProject Master Schedule None Preliminary Defined Defined DefinedEscalation Strategy None Preliminary Defined Defined DefinedWork Breakdown Structure None Preliminary Defined Defined DefinedProject Code of Accounts None Preliminary Defined Defined DefinedContracting Strategy Assumed Assumed Preliminary Defined DefinedEngineering Deliverables:Block Flow Diagrams S/P P/C C C CPlot Plans S P/C C CProcess Flow Diagrams (PFDs) S/P P/C C CUtility Flow Diagrams (UFDs) S/P P/C C CPiping & Instrument Diagrams (P&IDs) S P/C C CHeat & Material Balances S P/C C CProcess Equipment List S/P P/C C CUtility Equipment List S/P P/C C CElectrical One-Line Drawings S/P P/C C CSpecifications & Datasheets S P/C C CGeneral Equipment Arrangement Drawings S P/C C CSpare Parts Listings S/P P CMechanical Discipline Drawings S P P/CElectrical Discipline Drawings S P P/CInstrumentation/Control System Discipline Drawings S P P/CCivil/Structural/Site Discipline Drawings S P P/CFigure 4. – Estimate Input Checklist and Maturity MatrixREFERENCESANSI Standard Z94.2-1989.
