Mr Pochin will replace Ross Murray who leaves after 30 years with the firm, the last 10 as a main board director.
Mr Pochin has been promoted from contracts director after being with the firm for 12 years.
He said: “Due to the current market conditions, this is proving to be an extremely challenging time for all construction companies. Having risen through the ranks at Pochin’s, I understand every part of the business.
"We have some excellent schemes under construction with leading developers and good opportunities for new work in the forthcoming months. With the support of the excellent team we have here, I am looking forward to steering the company into better times.”
