1 Presto Cost management for construction

3 Cost management in different stages Estimate - Instead of Excel - Integrated with BIM and other construction softwares Planning - From the PM and contractor viewpoints - Integrated with time planning software Execution - Integrating data from all the agents - Cost & profit information system

4 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 income & cost - The project manager needs to integrate data from all others and manage changes - The end user wants to see results

5 Global benefits of using Presto Construction specific software Structured information system - Predefined by design - Flexible for displaying and delivering 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

6 Simple architecture, powerful connections Presto is used independently by the different agents - Each agent uses the Presto relevant components he needs - Each agent sends to others only the required information - The information is structured to integrate seamlessly among all actors Presto is not perceived as a control system, but as a support tool

7 Balance: cost, time and quantity Many information systems for construction are based on time or money. Planning systems are based on time and activities - Activities are too many to control costs - Schedule requires constant updating Accounting systems are based on money - They cannot accurately measure progress or make predictions. Presto is based on monitoring quantities.

8 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

9 Presto in the estimate stage Oriented to information reuse and exchange A single format allows data exchange in any direction - Price databases - Products catalogues - Estimate and planning - Cost control Work units may be reused between estimates - Based on the (open) coding system - With unit prices and rates - Overheads adapt to destination estimate

10 Open information system One source, multiple outputs Once the 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.

11 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 an 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

12 Presto in the planning stage Planning is the basis for economic control by the PM project manager Cost planning is based ON Cost or income centers Months Quantities NOT ON Activities Days Money / Time Bidirectional link to Primavera and Project avoids retyping information and mistakes

13 Presto in the planning stage From the PM viewpoint 3D 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

14 Presto in the planning stage From the PM viewpoint Information sent by the agents integrates into the PM information system - Initial estimate - Approved & pending changes The PM can show results to the client as soon as data is received - This cannot be achieved with underground computing, such as Excel. Customization may be performed by Presto, the PM or the user itself

15 Presto in the planning stage Financial planning Based on real payment terms

16 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

17 Presto in the planning stage Resources by financial periods

18 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

19 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

20 Earned value management From the PM or the contractor point of view

21 Presto: economic model Price Quantity Estimate Contract price Target Expected cost Execution Actual cost Estimate Project Estimate Certificación PM approved Certification Target Revised project Total production Initial target BAC Project cost EAC Planning Target to date Planned production Planned value PV Execution Real quantity Actual production Earned value EV Actual cost AC

22 Added value 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 and variation orders Standard methodology Quick start-up In time to make decisions
