John Gibb and Son consisted of John Gibb, a Scottish civil engineer and contractor (1776-1850), and his son Alexander Gibb (1804-1867) also a civil engineer. They worked together on several contracts from the 1820s onwards. After his father's death, Alexander continued to work as a Civil Engineer and in the quarrying of granite in Aberdeen.

They undertook the construction of the Wet Dock and other works, under the direction of Mr. Telford, by whom was also intrusted to them the erection of the Dean Bridge, near Edinburgh. Their attention being directed to railway works, Mr. Gibb and his son undertook, in 1836, the building of the Victoria Bridge, over the River Wear, on the line of the Durham Junction Railway, under Mr. Thomas Harrison. The last considerable work in which he was engaged, was the contract for the works across the Almond Valley, on the Edinburgh and Glasgow line, under Mr. Miller, and soon after its completion, in consequence of the decline of his health, Mr. Gibb retired from active employment.
