Toby Underwood and Ian Green of PricewaterhouseCoopers have been appointed joint administrators after the £16m turnover firm failed to renew its banking facilities.
Around 100 staff at the North East mid-market builder have been laid off with a few kept on to help with the administration.
The business was established 30-years ago and included mechanical and electrical plumbing outfit Gilwood Mast, and machinery and equipment hire business D&K Plant Hire.
Dorin managing director Richard Brown has separately launched D&K Hire Services and re-employed some staff from D&K Plant Hire.
The firm’s most recent accounts show that it made a pre-tax loss of £287,000 in the 12 months to June 30 2009, compared with a pre-tax profit of £304,000 in the previous year.
Brown told local newspaper The Journal: “I’m sad that we have had to put the business into administration, given that we had work in the pipeline.
“I have now set up a separate plant hire business and have re-employed 20 workers from D&K Plant Hire.”
