Here are the pieces, now build a bridge

Before any fabrication could take place at the marine yard, the site had to first undergo strengthening work in preparation for receiving, fabricating and storing shipments of bridge-building steel sections.

Over a two-year period, deck fabrication facilities were created, including kitting out the 50,000m2 storage yard with 800 fixed and moveable concrete support plinths to construct a complex deck section assembly line.

In May 2014, the first of four major shipments arrived in the Firth of Forth, carrying the impressive steel structures (each weighing between 200 and 350 tonnes) that would ultimately form the Queensferry Crossing’s 122 deck sections.
