RESTO

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

P

RESTO

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

LOBAL BENEFITS OF USING

P

RESTO

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

(5)

P

RESTO 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

(6)

P

RESTO 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

CAD

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

O

PEN 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.

 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

ANAGEMENT

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
