Bentley Completes Acquisition of STAAD Product Lines.

EXTON, Pa. -- Bentley Systems, Incorporated today announced that it has completed its acquisition of the Research Engineers International (REI) business from netGuru, Inc. The business features the STAAD.Pro line of leading structural engineering analysis software, which is now offered by Bentley worldwide.

STAAD.Pro facilitates the design of steel, concrete, timber, and aluminum structures for buildings, plants, tunnels, bridges, and more. It offers a state-of-the-art user interface, visualization tools, and advanced finite element and dynamic analysis capabilities for multi-material design.

Commenting on the acquisition, Buddy Cleveland, senior vice president, Bentley Software, said, "Bentley extends a warm welcome to all STAAD users - now numbering over 19,000 in more than 100 countries. I want to assure them that we will make their transition to the Bentley user community as seamless as possible by providing product support and services that are nothing short of world class."

Continued Cleveland, "The acquisition of the REI business underscores our common vision of integrating design and analysis, as well as of integrating analysis across the disciplines of building, plant, and civil. This unified, streamlined approach is already resulting in higher quality of work and accelerated design - benefits that this acquisition will serve to extend and expand."

Added Santanu Das, who served as netGuru's COO and is now Bentley vice president, product development, Integrated Engineering Group, "The opportunity to deliver best-in-class structural design solutions to the global market that Bentley serves with its broad line of software is unprecedented. Speaking for the entire REI organization joining Bentley, we are very excited about this synergy with Bentley and its comprehensive portfolio."

Bentley plans to continue developing STAAD.Pro as well as the next-generation STAAD.X product lines currently under development. These will include industry-specific analysis solutions that address particular needs for the design of bridges, transmission towers, commercial buildings, and offshore platforms.

In addition, Bentley will develop integrated solutions to provide 3D structural modeling, analysis, design, and documentation in a single environment, and will integrate STAAD products with its existing applications, such as MicroStation, Bentley Structural, Bentley Rebar, and the leading pipe stress application, Bentley AutoPIPE. These interoperating solutions will substantially boost quality and productivity by allowing users to work interactively with all of their critical applications.
