Using the latest technology remote-controlled drone camera, he has been taking aerial video and photographs of the Bupa Care New Zealand rest-home taking shape below.
The French-made Parrot AR. Drone 2.0, which only came on the market last year, looks like a mini-spaceship and is powered by a small electric motor.
Mr Klein controls it by touching joystick icons on his smartphone screen.
The images are saved to his phone, and he can also download the video on to his laptop and create still images.
The drone can fly up to 50m above the ground, although Mr Klein said its lightweight construction meant it was easily buffeted by winds and worked best on very calm days.
He bought it in October ''for a bit of a laugh'' but said he had found the camera useful.
Mr Klein and his colleague Rae Rennie, of Armitage Williams Project Management, are jointly managing the rest-home project in Racecourse Rd, Invercargill.
A 60-bed facility is being constructed which will house a mix of rest-home, hospital and dementia patients.
Work is also continuing on the retirement village next door, where the second phase of 20 villas and a community centre have just been started.
They are expected to be completed by May or June.
