For Rick Gossow, big machines and earthmoving are both his profession and his passion. He’s been working in civil construction since he was 19 years old, largely as an operator on graders and excavators.

When work for others took him too far from home and family, he decided it was time to start his own business. Building on his 14 years of experience, he formed Leading Edge Earthmoving in Victoria, Australia in 2017. He bought a Cat 304E excavator and focused on final trim grading and excavation for commercial and residential projects.

Over the course of three years, he’s built a strong, steady business, but continued to seek ways to improve quality and efficiency for his customers. He confirms, “I’m a one-man operation, so I’m always looking for affordable ways to drive productivity. This is a very competitive market segment. Anything that gives me an edge, saves me time and saves my clients money is invaluable.”

In particular, he noticed that he spent a lot of time getting in and out of the cab to check levels throughout the day. “I do a lot of small, private jobs and I was losing on average one to two hours a day checking levels,” says Gossow. “Not only am I losing time, but I’m burning fuel since the machine is just running. Losing just ten minutes of operation checking levels ten times a day adds up fast.”

He’d seen a lot of technology advancement, including 2D and 3D machine control, during his time on the road working for other contractors, so I knew there were tools that could automate leveling right from the cab, he says.

Laser Focused

He called Shane Wright, Sales Consultant at SITECH Construction Systems in Melbourne, Australia, to ask about a machine mounted laser receiver.

His response was not what Gossow expected. “He said I should look at the Trimble Earthworks Grade Control Platform for Excavators system instead,” said Gossow. “I had experience with 3D grade control systems in the past but knew those were not within my budget. But, Shane said the 2D capabilities would solve my leveling issues while providing additional benefit.”

Not only was the price right, but the grade control platform runs on a Trimble TD510 7” Touch Display. Gossow is also using the Trimble LC450 Laser Catcher fitted on the 2D Earthworks system with a Spectra Precision Grade Laser for consistent cross-site elevation benching.

“Once he sent the specs and pricing [about the 2D Earthworks], I was onboard,” said Gossow, who signed the purchase order the very next day and soon after, became the first contractor in Victoria to deploy the Trimble Earthworks 2D system.


On the Job

Currently, Gossow is using the 2D capabilities of the system on his Cat 304E excavator. The first opportunity to use the system was to dig a trench to prevent rainwater from flooding a client’s home and farm buildings. He followed up with a pad finish project for a farm storage unit and the finishing of a surface in preparation for a concrete pour.

“There are still certain features and functionality that I’m learning,” he said. “But, I know I’m more efficient, saving several hours in a day by staying focused on the job in the cab, and I’m more accurate. For everything I’ve used it on thus far, it’s awesome!”

Leading Edge Earthmoving’s experiences are attracting the attention of other small and midsize earthwork contractors in the area. Demolition contractor TerraFirma Excavations in Victoria, Australia has also adopted the Trimble Earthworks 2D system as well as the Spectra Precision Grade Laser to improve productivity and efficiency.

BTW Company, LTD. Uses Augmented Reality to Accelerate the Project Approval Process

Already longtime Trimble customers BTW chose Trimble SiteVision as the tool that could help them bring the power of augmented reality (AR) into their planning processes. BTW saw AR as a technology that would allow them to present an accurate future view of a project overlaid onto the actual construction site. By viewing the proposed project on-site in an augmented reality view with stakeholders, they could communicate the project concept and design phase more effectively. They could also help stakeholders gain a far better understanding of the finished result and the potential effects on the surrounding environment.

New Trimble® X7 plays its part in Scanning History

Ever since the Trimble® X7 was introduced into the market in Australia, MinStaff Survey has been eager to get hold of one, and that became a reality recently when SITECH Construction Systems’ Chris Reynolds and UPG's Kieran Dinuzzo took their demo unit out for MinStaff Survey to trial.  The results were so impressive they bought one.

MinStaff Survey was established in 1995 as a surveying solution to underground mine development projects throughout Central and Western NSW and for a decade specialised in the provision of surveying services to major mine development projects throughout the Eastern States of Australia.

2006 saw a relocation to Toowoomba in Queensland for the company, where they are still based today and with over 50 qualified surveyors has become a multi-discipline consulting surveying firm offering a full range of surveying services to both private companies (developers, designers, builders, miners, and contractors) and the public sector.

Recently they were tasked with a complete building scan on the Soldiers Memorial Hall building in Toowoomba.  The building has been subjected to numerous extensions over the years and suspected movement detected meant a thorough investigation before new renovations and structural modifications could be implemented.

“When we trialled the system, we completed in one hour a job we initially thought may take about four.  That was the real eye-opener for us,” said Jake Laing, General Manager.

“The X7 is just one of the pieces used on this latest project.  We combined the X7 and T10 with Trimble Perspective, the Trimble SX10 Total Station to geo-reference the scans on a known survey datum and a Trimble Dini for level control and baseline monitoring of the external structure, and of course Trimble Business Center played an integral part in bringing all the data together.”

“We did face some challenges – the building was multiple stories with minimal access and egress points, and we needed to tie the scan data together between floors, as well as capture the interior and exterior data.”  said Jake.  “The field works took us three days with 290 scans, and we completed the office works in one day.”

The Soldiers Memorial Hall was built in three stages.  From 1923 – 1924 the main structure was built, then additions in 1930 and 1957 saw the building completed as a tribute to those who had served in the First World War.  At the time of opening in 1924 the building comprised two stories with a single gable to each side of the roof, together with a small brick building at the rear, possibly used as additional storerooms and a public lavatory.

“When we trialled the system, we completed in one hour a job we initially thought may take about four. That was the real eye opener for us,” said Jake Laing, General Manager.

“Today the structure consists of multiple stories and many small rooms, which all have limited access,” explains Jake.  “In order to survey the vast amount of data required there was only the one option - to provide a point cloud survey using the Trimble X7.  This allowed seamless cloud-to-cloud registration with real-time viewing on the T10 tablet in the Trimble Perspective software.  With the fast scan speeds, we were able to complete +100 scan stations a day with minimal impact on staff who continued to work in the building.  The ability to export a panoramic image of each scan station was deemed extremely beneficial for the client because they now have great quality images of the whole building to add to their archives.”

The team was able to do a closed-loop traverse through multiple levels of the building with scan targets, adjusting the traverse in TBC then geo-referencing the point cloud to scan the targets.  This ensured confidence in the data, that there was no angular swing in the point cloud due to cloud-to-cloud registering misalignment, as well as ensuring no difference in data between levels.

Although fairly new to the team, the Trimble X7 has had plenty of use every week, whether it be from extensive point cloud scans for building design to tenancy lease surveys and as-constructed surveys.  “Final as-constructed surveys can be scanned with a high level of accuracy and detail in only a couple of minutes compared to using conventional survey equipment”, states Jake, “And the benefits we’ve found from the X7 is the ability to complete a full scan with imagery in under three minutes.  This allows for full data capture with minimal inconvenience to any workspace.”

“And the benefits we’ve found from the X7 is the ability to complete a full scan with imagery in under three minutes.  This allows for full data capture with minimal inconvenience to any workspace.”

“Most projects come with strict budgets and time-lines”, said Jake, “But the X7 has improved the amount and the quality of the data we can provide to our clients, all with a much faster turnaround, than had we used the SX10, which would have done the job but taken a lot longer to do.  Or with us undertaking hard measurements for floor plans, which wouldn’t have been feasible in terms of cost, time, and data storage constraints.”

Kieran Dinuzzo, Technical Consultant had no doubts when looking at the project that the Trimble X7 and Perspective Software was a perfect fit based on the ability to have a registered, refined, colourised point-cloud ready to bring straight into Trimble Business Centre, which would instill a lot of confidence in the client in achieving a high-end result.  And, given this project was mid-COVID and no face-to-face training was available SITECH and UPG were set up and ready to run the project remotely.  However, with the simplicity and performance of Perspective, this wasn’t necessary.  MinStaff picked it up easily and were away.
