He was the great-grandson of John Gibb, an early member of the Institution of Civil Engineers and a colleague of its first President, Thomas Telford.

He joined his father's company, Easton, Gibb & Son, in 1900 when they were building the King Edward VII Bridge at Kew.

[6] Gibb later worked on the construction of the Rosyth naval dockyard where he is credited with accelerating the programme so that it was brought into use during the First World War.

Additionally he was a technical adviser to the Treasury on civil engineering schemes financed under the Trades Facilities Act and he was transport representative for the ministry on the Forth Conservancy Board.

[3] This led their engagement in 1939 to undertake the design and supervision of three ordnance factories for the Ministry of Supply, work which would continue throughout the Second World War.

His proposers were John MacKay Bernard, Sir Thomas Hudson Beare, Ernest Wedderburn, and William Archer Tait.
