Interflow celebrates 80 years of innovation and service

23 January 2017 , 0

Interflow marked the 80th anniversary of its founding on 11 November 2016; the milestone provided an opportunity to reflect on and celebrate its past success and the strengths of the company culture as it looks to the future.

On 11 November 1936, Harold Weaver, more commonly known as Bill, founded General Constructions. Its first contract was the construction of several sewers in the Sydney suburb of Northbridge. In the years following its establishment, the company went on to construct many of the original sewers and water supply pipelines throughout Australia, and played an integral role in the establishing early water infrastructure.

General Constructions gained a reputation for quality and reliability under the watchful management of Mr Weaver. His tenet was that “each project undertaken must add to the company’s reputation for competence, reliability and honesty”.

In 1960, Mr Weaver handed the reins of the company over to the second generation, appointing his son Ron Weaver as Managing Director. Over the years, Ron continued to lead the company, always aiming to keep one step ahead of the competition by providing innovative solutions to customers and by finding better ways to do the work. This attitude is still deeply engrained in the culture of Interflow to this day.

In 1990, Geoff Weaver, Bill’s grandson, was appointed Managing Director and in 1996 General Constructions merged with associated companies Vortec and Pipeline Rehabilitations to form what is now known as Interflow.

Today, Interflow is a successful and innovative organisation that specialises in water infrastructure renewal, with an extensive history of successful project and program delivery.

Since 1997, its achievements have been recognised with 18 prestigious national and international awards, most recently winning the ASTT 2015 Rehabilitation Project of the Year award for the its work on the S1 Main Sewer Upgrade in Brisbane.

Interflow’s reputation has been built on the company living and breathing the core values that were established by Bill Weaver in 1936: honesty, reliability, and competence. The company continues to act and communicate with its clients in a way that’s sincere, truthful and straightforward.

Geoff Weaver says “For 80 years Interflow has focused on solving clients’ problems – we have become a trusted ‘partner’, we don’t compromise on quality or safety, and that is something of which we are very proud. I am proud to say that the ‘Interflow culture’ – our way of doing things – is clearly evident in the people of Interflow today, because it has been passed down by the people of Interflow over what is now four generations and 80 years.”

“Our clients come to us to solve their problems because they know we have the expertise to offer cost effective, innovative and alternative solutions. As we look forward to the future, we will continue to challenge the status quo by having a ‘can-do’ attitude to find a better way. That is how we will continue to look after our customers and be successful over the next 80 years,” he says.
