Clash consultant

Binnie Black & Veatch's Hong Kong operation Binnie Consultants has been involved in eight projects at the huge airport development. The largest of them was a major airport utilities clash analysis.

The clash analysis required integrating an array of over 20 utilities, including aviation fuel lines, water supply pipes, communication ducts and power lines into a massive underground network. 'There were potentially thousands of clashes,' explains Binnie director Nick Townsend.

Binnie created a suite of software programs to identify and resolve these clashes and produced combined utility drawings. The core of the programs is a database created from over 1,600 utilities drawings and spreadsheets.

The programs pinpointed clashes in tabular and graphical form and drew cross-sections at any location to show the relative position of different utilities. They also showed the type of construction planned, the depth and whether any bedding or foundation was required. From this it was possible to decide on the order in which utilities should be laid down.

The drawings were prepared in both Intergraph Microstation and AutoCAD formats to meet the requirements of the Airport Authority and contractors.
