In 1947, the company became a limited liability company with Willie Logan, his sister Mrs Scott, Alistair Logan and Mr. J.B. Baird as its’ Directors. Willie was a flamboyant building contractor and entrepreneur which saw the company involved in many significant construction projects, including the Garry-Moriston, Conon Hydro-Electric Schemes and the building of the Tay Road Bridge.

Work on the Tay Road Bridge commenced in March 1963 with a milestone in the bridge construction being achieved on 15th February 1965 as the closing of the final gap in the temporary bridge saw Fife and Angus being at last linked. At a peak three hundred and sixty men worked on the bridge construction.

Sadly, contractor Willie Logan never saw his bridge completed. He was killed in January 1966 when his private plane crashed at Dulnain Hill near Inverness.

He had been returning from an onsite visit to the works on the Tay Bridge and due to his own aircraft being on other commitments, he chartered an aircrfat from Strathallan. He was 10 hours short of gaining his pilots licence.

Professor Robert Grieve, chairman of the Highland Development Board paid tribute syaing:

“Willie Logan was a legend and will remain a legend in the Highlands. He created an industry of national scale and importance from a headquarters in the Highlands. He was one of the few really big symbols of confidence by the Highlander in the Highlands. His death cannot destroy that, and his example will never now be forgtotten.”

 His gravestone at Fodderty cemetery, near Strathpeffer, is in the shape of a section of the Tay Road Bridge. The inscription reading:

“Man of vision, courage and integrity. A pioneer of hydro-electric construction and a wise master-builder who contributed much to his native land. He left monuments to his skill in many parts.”
