Securing the future
A new double-decker transit area at Auckland International Airport not only provides separation for inbound and outbound travellers it also highlights a fresh approach to terminal design
In any major commercial project, the tasks carried out behind the scenes are just as vital as the more obvious features. And, in the case of BN Walker Surveying, the company's work determined the actual positioning of all the foundations, structural building alignments and finished architectural elements and tenant fit-outs.
Director Bruce Walker says the company was involved at a very early stage, surveying the existing building to check structural dimensions and then setting out grid lines and benchmark data. This included determining high accuracy reference points, profiling the geometry of the complex ceilings, and positioning the escalators and lift shafts, he says.
"Our surveying instruments utilise computer and laser technology for set out. The geometry is then plotted with CAD software," he says.
Walker says working with complex geometry in restricted situations in the existing building was one of the more challenging aspects of the job. There was also a need to work pro-actively, particularly when entering new work zones, to keep the critical workface ahead of the tight programme.
