Building Information Modelling and the ease in which it allowed complex pipework to be implemented on the site of a recent upgrading project are the focus of a new article.

Water and Wastewater have published a story regarding renovation work on United UtilitiesLiverpool Wastewater Treatment Works that is being carried out by a join venture between Galliford Try, Costain and Atkins, aka GCA.

The project required the installation of a large diameter network of fabricated steel and ductile iron pipes, and due to the coating on the fabricated steel, cutting it on-site was exempt. This was where BIM, off-site pre-fabrication and clash detection proved crucial.

“We couldn’t have achieved the levels of fabrication accuracy without the co-ordinated 3D BIM model,” said GCA Senior Civil Engineer, Patrick Wills. “Fabricating steel pipe at very large diameters to the required accuracy is a difficult process, starting out with accurate dimensional data and following it through with a structured checking system lead to project success.”

The “very large diameters” referenced by Wills were ranging from 1,600mm to 2,200mm, with most elements of the pipework sitting incredibly close to one another. Collaboration was key towards successfully achieving their goal stated Gregory Hood, GCA Senior Engineer:

“Constructing the large diameter pipework was a collaborative process from start to finish. Using BIM, along with the early involvement of the construction team, enabled us to not only value engineer the scheme, but to also plan for the safe installation of the large sections of pipework and the precise placement of each individual fitting.”
