The AT board, at its first meeting last month, heard that a recent review of pedestrian safety found that a previous one-size-fits-all approach had dominated and was costing ratepayers too much.
This was despite having a range of other affordable solutions available.
The crossing was part of the State Highway 16 access road upgrade project, at the car park of the Main Rd shops.
The pre-cast unit was installed in one night, rather than over several days.
“We saved money due to the speed at which it was installed. The installation was just one night, versus the usual raised crossing which would take a week or two to install,” Burt said.
Burt said the pre-casts were laid out from 9pm, and work was completed by 5am. It opened to traffic that morning.
“AT is now investigating opportunities to roll out this approach more broadly wherever possible.”
He said 22 other crossings have been identified as suitable for the same approach.
In a social media post about the Kumeū project, Fulton Hogan’s national innovation lead Beaudene Pumipi said pre-casting had health and safety benefits in construction.
It had lower carbon emissions and largely negated the vagaries of the weather, being manufactured in a controlled environment, he said.
“There’s growing interest in how New Zealand can produce speed tables and other concrete road structures more efficiently and effectively,” Pumipi said.
Burt said their review of raised crossings estimated a reduction of around 30 per cent of these were required, compared to the current pipeline of projects.
