Causeway Technologies, providers of construction software and portal buildingwork.com, has appointed Robert Jeens as its chairman.
Jeens joins Causeway in a part-time post from trading site Mercadium, where he was the chairman. He has also served as deputy chairman of heating and building materials group Hepworth and as financial director of Woolwich.

"Causeway is a very interesting company, and there is a lot going on," said Jeens. "I can bring experience to the board and a more objective view, as my role is part time."

Jeens' responsibilities will include corporate governance for Causeway's 350 shareholders.

Chief executive officer of Causeway Phil Brown said Jeens suited its needs. "Robert Jeens had the four things we required: industry experience, knowledge of e-commerce, FTSE 100 experience and contacts in the City."

In a separate deal, Causeway has acquired Mercadium. The site was set up in April 2000 and investors included contractor Alfred McAlpine, building materials group Aggregate Industries and glass manufacturer Pilkington.
