"We need two cranes because it's a massive building," said Culum Manson, explaining that the dark blue Australian-made Favco crane was one of two Mansons bought from Mainzeal's receivers.
Mansons bought the silver and white German Hammerhead on that Victoria St West site in Singapore last decade, he said.
The business expects to erect its second ex-Mainzeal Favco on a city apartment site it wants to start early next year.
Auckland had a severe shortage of top-grade commercial office space, many tenants wanted to move and Manson predicted many more cranes going up shortly.
"There'll be another half a dozen in the next six months. We're going to see a massive spike in construction costs and activity. Costs will go up because of the demand," Manson predicted.
The two Victoria St West cranes could build up to eight levels before they were tied in or attached to structures, Manson said. After that, they could then go to any height as they crawled up the structures they create because sections could be added.
Up towards Spaghetti Junction, Kalmar Construction has a tower crane on the $250 millon Sugartree apartment site between Nelson St and Union St. The first block rising there will have 148 units, the second 220 and the third 195 units.
Chris Dibble, real estate consultants Colliers International's research manager, said cranes were a good sign.
"There is definitely more construction activity in the pipeline than we have seen for a few years, but it is coming off a low base. Net migration, population projections and business and consumer confidence are the key components that are building this momentum," Dibble said. "The revisions to previous GDP results which are expected to show higher levels of construction activity than previously thought suggests there has been more activity than was originally reported."
Investor confidence in the Auckland office sector had increased in the September quarter reaching 63 per cent, up from 36 per cent a year ago. Colliers found.
"This is the most confident investors have been since our records began in 2006," Colliers said. "The boost in confidence is a reflection of stronger fundamentals. Improving business expectations for the next 12 months should mean more new businesses and more expansion by existing businesses."
On Ponsonby Rd at the LOT 3 retail, office and studio development, Canam Construction is swinging its big rig between old buildings.
General manager Andrew Clark said the firm owned its crane, shipped back from Port Moresby where it was hauling equipment for a new hotel. Clark estimated the crane was 30m to 40m high, equivalent to a 13-level building, and said it would stay until around next March, bringing on pre-cast concrete panels, steel and other construction components.
"The market is definitely getting better," Clark said of the spectre of a crane-dotted Auckland skyline.
