Philadelphia, PA, October 5, 2004 - Industry-leader Primavera Systems, Inc., today announced the release of Primavera® Contractor - the only single-project planning and scheduling software solution built specifically for the construction industry.

Primavera Contractor makes it possible for the entire project team - from general contractor through subcontractors - to work together on a single, consolidated master schedule by providing timely status updates and change notification. Productivity is increased through better coordination and synchronization between contractors and subcontractors, and through improved scheduling of crews, material deliveries and equipment availability.

"I recommend that all of our subcontractors use Primavera Contractor because they will be able to send us their most up-to-date schedules, with costs, very quickly. This ensures CH2MHILL has the most accurate program information possible, and our subs will be more productive because the communication process is faster," said Saied Kartam, CH2MHILL Global Technology Leader for Planning and Scheduling / Regional Manager, Southwest Project Planning & Control.

"We are further expanding our commitment to the construction industry with Primavera Contractor. This new release offers the value of Primavera's construction-focused technology at a very affordable level," stated Joel Koppelman, Primavera CEO. "Many small and mid-sized contractors and subcontractors want to use Primavera products to improve their project management processes. With Primavera Contractor they have a solution that makes sense for their business and improves productivity."

Primavera Contractor enables contractors and subcontractors to work together better and build more accurate schedules through:

• Improved Scheduling and Communication

  With built-in project templates, views and graphics, Primavera Contractor makes scheduling and communication of project status quick, easy and available in a standard format. Subcontractors can communicate a "start-to-finish" view of activities and resources using critical path functionality and true work breakdown structure graphics. Embedded Claim Digger technology lets contractors view the changes subcontractors make to a schedule over the project's lifetime to identify schedule or cost padding that may push a project over budget.

• Fast, Professional Reporting

  Contractors and subcontractors can shorten the time it takes to prepare reports by using the more than 75 construction-specific report templates or Report Wizard included in Primavera Contractor. Fully customizable Gantt charts and PERT diagrams with trace logic provide professional-looking graphics for faster reporting of project status.

• Easy Schedule Exchange

  With Primavera Contractor, the general contractor can easily collect schedules created by subcontractors in Primavera or Microsoft Project. Subcontractors can e-mail entire updated project schedules to the general contractor, who, in turn, can simply use the Import/Export Wizard to incorporate them into the master schedule.

• Accurate Forecasting

  Primavera Contractor provides easy-to-understand views of cost and resource relationships for the most accurate forecasting possible. With accurate forecast data, contractors and the home office can quickly see how cost or resource allocations will affect the overall budget and project delivery.
