Bridge and constructional steel maker, of Middlesbrough[1]
1967 Was a subsidiary of Dorman Long; responsible for the design, fabrication and execution of the structural steelwork for the building to house Dorman Long's new basic oxygen plant[2]
1968 Subcontractors for construction of the Clifton M62 bridge across the River Irwell using an unusual construction method[3]
1969 Falling demand for structural steel led to closure of the Edinburgh works; the business employed more than 4000 people in all; works also at Glasgow, London, Manchester and Middlesbrough[4]
1972 In preparation for introduction of private capital, British Steel created a constructional engineering division and named it Redpath Dorman Long, a shell company, which would include the existing company which was renamed Redpath Dorman Long (Contracting)[5]
1980 Redpath Offshore Ltd came into public ownership - announcement by British Steel Corporation[6]
1982 Redpath Dorman Long was sold to Trafalgar House for £10 million. British Steel chairman Ian MacGregor wanted to concentrate the corporation's activities purely on iron and steel making.[7] Eventually merged with Cleveland Bridge and Engineering Co. From the 1st October the structural engineering division was controlled under the collective umbrella of Cleveland Redpath Engineering Holdings.[8]
