The Forth Bridge


Overview of The Forth Bridge

The resulting out-cry led to Bouch loosing the confidence of the Northern British Trains, who handed the work over to Sir John Fowler and Benjamin Baker. Their innovative design and construction had become possible due to improvements in feed in tariffs steel initially instigated by the Bessemer Process and subsequently perfected by the Open-Hearth process pioneered by Siemens- Martin, which provided steel of consistent quality, which led to the British Board of Trade permitting the use of all steel constructions in structural retro sweets engineering in 1875.

Fowler and Baker were free to design a bridge using a cantilever construction out of steel. Due to the Tay Bridge disaster, it was essential that public confidence was restored in large bridge engineering projects, this led to the design being over-engineered, which is why it remains as strong now as it ever was.

With an ever increasing flow of road traffic, which was rapidly developing after the introduction of motorised transport, the need for a Road Bridge across the Forth, became ever more pressing and in 1923 plans were put forward to by J Inglis Ker. It wasn’t until 1929 that the plans were developed any further and a survey was commissioned to identify suitable crossing points. Three potential sites were identified and the possibility of a road tunnel was again mooted.

Topographic survey requires skill, common sense and a good working knowledge of the construction industry. Our surveyors meet all these needs by being mature and experienced; often working closely with Engineers and Designers to produce useful and appropriate data and drawings.
