The brief
Traffic could not be fully diverted, so the box had to be built in bays with decking reinstated over each completed section before the next one opened.
Public-sector documentation requirements meant every panel, cube and anchor needed a signed record before payment.
What we did
One contractor from the borelog to the final test certificate.
Six construction bays with road decking reinstated over each before the next was opened.
1,000 mm panels to 26 m forming the permanent station box walls.
King post and decking system carrying live traffic over the open excavation.
Panel-by-panel QA file accepted by the authority without a single re-submission.

On site
“The documentation pack was the cleanest we received on the package. That matters more than people think on a public contract.”
