It has been 60 years since Karl Lupis first became a registered surveyor and the well-known local identity doesn't show any signs of slowing down soon.

Why would he?

His skills are in demand and he enjoys the challenge of the job he's been dedicated to for the past six decades.

The remarkable milestone was celebrated at Kneebone and Associates Solicitors with some of the people Karl Lupis Surveying has been closely associated with over many years.

Back at the work desk, Mr Lupis's Certificate of Currency and of registration from 1964 hang on the wall.

He will never take them for granted - as the role of a surveyor is an important one.

From major roads to carports, surveyors are involved ahead of every development: getting levels, measurements, easements and all the necessary information.

They're at the frontline of growth in our community.

"Surveyors are the barometer for the economy: if we're busy, it means good times ahead," Mr Lupis said.

"We're the first ones on the job. If there's a surveyor there, something's going to happen."

When Mr Lupis began, his pathway into the role was to become articled to a registered surveyor: he worked in the heart of Sydney in those days.

"We had 12 subjects to pass exams in - over four years," he said.

He attended Tech and studied at night while working and gaining experience. Today surveyors study through university.

Mr Lupis came to Forbes in 1969, at the time to work for the shire.

"It was a wet show day," he remembered of his arrival.

"In 1970 we surveyed up the centreline of the Newell Highway from Woolshed Road to the mad mile at Tichborne - up the middle of the road - imagine trying to do that today."

Yet the task was done, safely, with very simple instruments and the measurements and levels were returned to council to plan the reconstruction of the road.

It's no surprise that technology has drastically changed the way a surveyor's work is done since those years.

Mr Lupis started his own business in 1981, and that continues today with long-serving team members Shayne Staines and Peter Yapp.

He still has a Gunter chain, its 100 links formerly the standard for a surveyor, as well as the wire measure that replaced it.

Electronic measuring followed, then global navigation satellite system which we commonly know as GPS.

Today work can be done with drones.

Mr Lupis can only describe the rise of technology as "exponential" and of course the regulations have to change with it. The pace has also picked up.

In the early days surveyors had to send to Sydney by mail for the documentation they needed and that meant a two-week turnaround.

It's not just technology Mr Lupis has seen change, it's Forbes itself.

"Opposite the high school, that was all wheat paddocks," he recalled of the early years he was in Forbes and the now populated streets he surveyed pre-construction.

"Past the high school, they were holding yards for stock I think."

Karl Lupis Surveying has a long-serving team: Shayne Staines has been there 37 years and Peter Yapp about 15 years.

They've covered a lot of country and seen a lot of change, but Mr Lupis's commitment to the importance of their job is unwavering.

"People don't realise that with the integrity of the registered surveyors, the Crown can guarantee title to anyone's block of land," he said.

"If you didn't have that integrity then mortgagees could not lend money on that block of land."
