Bentley Acquires Logos To Deliver Innovative Vision for Isometrics

Will Embed Logos' PlantSpace Isometrics Within DigitalPlant, Enabling
Owner-Operators to Cost-Effectively Create, Edit Intelligent As-Built Piping Isometrics
Exton, Pa. - March 21, 2006 - Bentley Systems, Incorporated today announced that it has acquired Logos BV, an international provider of the isometric software tools PlantSpace Isometrics (formerly known as L/ISO and IsoExtractor).

Bentley will embed Logos' intelligent isometric generation and production tools within its DigitalPlant solution. This will enable owner-operators to create and edit intelligent as-built piping isometrics and link this data to their enterprise systems.

"This strategic acquisition," explained Rob Whitesell, vice president, Bentley Plant, "will help us provide plant owner-operators with enhanced solutions - solutions that offer greater efficiencies in the creation and management of piping isometrics, as well as in other engineering workflows and business processes. PlantSpace Isometrics is a natural complement to Bentley's DigitalPlant portfolio, which provides comprehensive solutions for the distributed enterprise."

Added Gerard Klok, CEO, Logos, "As a result of the close cooperation we have had with Bentley over the past four to five years, this is a perfect next step for both our companies. We are very familiar with Bentley's many capabilities and extensive market reach. We bring to Bentley unique software that, combined with the breadth of Bentley's DigitialPlant offerings, will enable users to make a step change improvement in the way plant piping is maintained and documented."

For mass production of fabrication isometrics during the engineering and construction phases of a project, Bentley continues its long-standing partnership with Alias for Isogen, which is directly embedded in Bentley Piping. However, for situations in which automatic isometric generation is not feasible or does not meet user requirements, the Logos tools allow as-built isometric drawings to be easily sketched and validated against a 3D model or a scanned point cloud model. The isometrics generated can then be automatically registered, tracked, and managed alongside the original 3D models. In addition, any field or operations changes can be tracked and constantly merged to provide an accurate as-built 3D piping model throughout the life of the asset.

The up-to-date model is thus available for subsequent ongoing engineering analyses such as pipe stress and fluid flow. Also, because the intelligent isometric contains detailed engineering data that can be managed at a component level, the isometrics can be linked to business and procurement systems to optimize operations and maintenance activities.
