PRESTO: COST MANAGEMENT FOR CONSTRUCTION Successful projects T4 Barajas Airport, Madrid, Spain AVE Alta Velocidad española
PRESTO Cost management in different stages Estimate Instead of Excel Integrated with BIM and other construction software Planning From the PM and contractor viewpoints Integrated with time planning software Execution Integrating data from all the agents Cost & profit information system
PRESTO Cost management for all the agents involved in construction Supporting their different needs The project team needs a powerful estimation system Planners need to analyze cost, resources and financing The contractor needs a system controlling both income and cost The project manager needs to integrate data from all others and manage changes The end user wants to see results
GLOBAL BENEFITS OF USING PRESTO Construction specific software Structured information system Predefined by design Flexible for display and delivery of information No underground computing Professionals focus in the core business, not in programming. Excel is used for information output, not for data input Quick start, no implementation is required The state of the art in Windows software
PRESTO IN THE ESTIMATE STAGE Flexible Cost WBS (CBS) CBS elements share a common structure: Divisions: MasterFormat, Uniformat or any other Work units: custom or from price databases Resources breakdown: any number of labor, equipment, materials and other components CBS may match or not the planning WBS Direct site, home and profit overheads and specific percentages for work units Cost based in unit rates and quantities
PRESTO IN THE ESTIMATE STAGE Oriented to information re-use and exchange A single format allows data exchange in any direction Price databases Products catalogues Estimate and planning Cost control Work units may be re-used between estimates Based on the (open) coding system With unit prices and rates Overheads adapt to destination estimate
BIM INTEGRATION: REVIT, ALLPLAN, ARCHICAD Quantities, location and cost relevant data is retrieved from the model even if no special action is performed by the project team Catalogues in BIM format for the easy selection of work units Data may be checked before being added to the estimate Optional feed-back from the estimate to the model Selected estimate elements are displayed in the model Estimate and model may evolve at the same time Changes, additions and deletions between successive data versions are detected Manual changes in the estimate do not mix with BIM data
OPEN INFORMATION SYSTEM One source, multiple outputs Once information is in Presto, it may be exported in any format Open, customizable report system, Access style Printer, PDF, TXT or RTF printing of any report Excel: full estimate or specific windows export Inserts data in Excel or Word predefined templates Full export and import to/from Microsoft Access WBS and resources output in Primavera XML format Presto files may be created from Excel files, GAEB XML, BC3 and other national formats.
PRESTO IN THE PLANNING STAGE From the PM viewpoint Three dimensional matrix estimate CBS (divisions and work units) Activities (areas, sectors, sections, levels, tasks...) Financial periods (months) Cost planning (by financial periods) Convert from Primavera activities and dates Quick planning by "S" curves Financial planning Tendering and RFP Request For Proposals
PRESTO IN THE PLANNING STAGE Financial planning Based on real payment terms
PRESTO IN THE PLANNING STAGE From the contractor viewpoint Cost and income analysis Unit cost (standard rates and price databases) Operational estimating (first principles) Overheads Tendering and planning Resources by dates, financial periods and cost centers Manpower and equipment analysis Contracting and purchases management
PRESTO IN THE PLANNING STAGE Resources by financial periods
PRESTO IN THE CONSTRUCTION STAGE Income and cost tracking Payment Certificates for public and private clients Tracking models Planning, construction and certification by financial periods Cost tracking by "S" curve patterns EVM Earned Value Management Process management Controlled exchange of information between agents Variations from the initial estimate
EARNED VALUE MANAGEMENT A formal methodology for monitoring deviations Actual work valued at estimated cost EV / Actual Cost = Cost Performance EV / Planned Value = Schedule Performance Accurate estimation of current progress, cost and time at completion Predefined, common terminology for all the agents Independent of bar chart planning Based on the information normally available to the PM
EARNED VALUE MANAGEMENT From the PM or the contractor point of view
ECONOMIC MODEL FOR CONSTRUCTION Price Quantity Estimate Project Certificated PM approved Target Revised project Planning Target to date Execution Real quantity Estimate Contract price Estimate Certification Target Expected cost Total production Initial target BAC Planned production Planned value PV Actual production Earned value EV Execution Actual cost Project cost EAC Actual cost AC
PRESTO FOR THE END CLIENT Presto advantage for the Client is obtaining accurate and verified information Easy to understand information system (Presto and Excel) Display of initial estimate, approved changes, variation orders Standard methodology Quick start-up In time to make decisions
