KITCHENER — Coreworx Inc., a Kitchener-based maker of software for energy and mining companies, has acquired a Calgary software company that also is active in that sector.

Decision Dynamics Technology Ltd. develops software that helps oil, gas and electric power companies manage and forecast costs, while Coreworx specializes in the management of documents, drawings and completion of tasks, said Brett Shellhammer, senior vice-president of marketing at Coreworx.

Decision Dynamics offers “a very complementary piece of technology” to what Coreworx does, he said in an interview.

Coreworx began working with Decision Dynamics about a year ago with a few joint customers, Shellhammer said. A few months ago, discussions started about a possible acquisition. “It’s a natural fit,” said Shellhammer.

Under the deal, Decision Dynamics shareholders will receive one million common shares of Acorn Energy, Coreworx’s parent company. The deal values Decision Dynamics at $6.2 million US.

The sale is subject to the approval of Decision Dynamics shareholders, but has been recommended by the company’s board of directors.

Coreworx employs about 50 people at its head office in Kitchener and 15 others at offices in Houston, Louisiana, Calgary and Australia. It services a portfolio of more than 400 capital projects in 50 countries.

Decision Dynamics employs about 25 people in Calgary.

Decision Dynamics’ “project controls solution with its cost management and cost forecasting capabilities is a great complement to our Coreworx project information control platform which is widely used on major capital projects,” Coreworx chief executive officer Ray Simonson said in a news release.
