One of New Zealand’s most ambitious tunnelling projects is one step closer, after Watercare issued a request for proposals for the Central Interceptor project.
Four construction contractors, short-listed earlier this year, now have four months to prepare their proposals.
“We’re running a tight ship here. Keeping to schedule on this critical project is crucial for the industry,” said Central Interceptor Executive Program Director Shayne Cunis.
“There is a lot at stake – these contractors and all interested parties need certainty and confidence in the process and timeframe.
“Our intention has always been to stick to our plan.
“We do what we say and the people of Auckland can take comfort that Watercare is delivering on its promises of improving Auckland’s infrastructure.”
The project includes the construction of a 13 km long wastewater tunnel, with an internal diameter of 4.5 m, as well as 4.4 km of link sewers that range between 2.1 and 2.4 m in diameter and a terminal pump station with 6 m3/s capacity.
The contractors’ proposals are due in 14 September, before the winning bid is announced in February 2019.
