Three places construction projects lose money and how GNSS helps close the gap
You estimated the job carefully: planned it, budgeted it, built it. So why did it close out below the number you started with, and why can’t you point to the one thing that did it?
On most construction projects, the money doesn’t leave in one big loss. It leaks out in small, ordinary moments that never look like money problems on site: a measurement that didn’t line up, a crew standing around waiting, a quantity you can’t quite prove when the invoice goes out.
These three leaks have one thing in common. They all come down to positioning. Knowing exactly where things are, and being able to prove it.
GNSS gives you the satellite positioning behind survey-grade accuracy. It doesn’t change the fundamentals—you still move dirt and pour concrete. What it does is cut construction profit loss, by reducing how often those costly errors happen and how much they cost you.
Field checks save you from rework
The formwork goes up on a foundation that’s slightly out of position. The concrete gets poured. Weeks later, the structural steel arrives, and nothing lines up.
For example: you call the steel fabricator. Their measurements check out. Your crew ran the layout last week, and they’re sure they did it right. Everyone worked from the information they had, but somewhere along the way, a bad number slipped through.
By the time you trace it, the concrete is set. Now you’re building the same structure a second time: paying for the labor, the material, and the delay, then explaining all of it to the client.
The mistake itself was small. What made it expensive was how long it went unnoticed.
A field crew with a high-accuracy GNSS receiver can run that layout check in minutes. Instead of trusting an old set of coordinates or waiting days for someone to verify a placement, they check the points on the ground against the digital model right there.
You catch the misalignment before the pour, not after.
A number passes through a lot of hands on a single job: from field to office, app to app, crew to crew. Every handoff is another chance for the wrong one to slip through. Garney, a US contractor that builds water and wastewater infrastructure, treats that as a rule worth designing around. Construction Technology Manager Scott Brown puts it simply:
“The fewer times we can handle the information, the better.” — Scott Brown, Construction Technology Manager, Garney

On-site layout keeps crews moving
It’s morning. The excavator is fueled and ready. The operator, the foreman, and a few crew members are standing next to it. They’re waiting because the surveyor hasn’t arrived yet to mark the points and check the grades.
This is the bottleneck nobody puts in the budget, and everybody pays for. While a specialist handles a routine measurement, payroll keeps running, and the day’s momentum stalls before it starts.
KLS Earthworks, a civil construction company working across Calgary and Saskatoon, knew this bottleneck well. Before the field crews had their own receivers, Survey Manager Daniel Kenny spent his days driving between sites to run routine checks himself:
“I went from running to 11 jobs a day with no time to think, to having four units in the field. It’s saved me hours of driving and chasing down jobs.”
— Daniel Kenny, Survey Manager, KLS Earthworks
A GNSS receiver that’s straightforward to operate changes the math. Your own field engineers and foremen handle the routine layout and grade checks, so work doesn’t stop for a basic measurement. This doesn’t replace the surveyor—it frees them up for the precise, high-stakes work that actually needs their expertise, while the rest of the site keeps moving.
For Kenny, that was the real shift. The crews kept moving, and his survey team got their time back for the work that matters:
“Emlid’s RTK GNSS technology changed how we operate at KLS Earthworks & Environmental. Projects are no longer delayed because supervisors can now confidently confirm grades and perform underground layout themselves. My surveying team can focus on more strategic work instead of rushing between sites to verify layout.”

Survey data backs every invoice
Cut and fill volumes, material quantities, and paving areas are the numbers a project bills on. They’re also where most of the friction shows up when it’s time to invoice a client or pay a subcontractor.
When a quantity gets challenged, an estimate won’t hold up. This is where payments stall, and disputes start. Both sides arrive with their own figures, and neither has an actual survey to stand behind.
A quick surface survey done by the field team changes that. With a survey-grade GNSS, superintendents or site managers can capture precise topographic data before and after the work, so your quantities come from field measurements instead of an educated guess. When the client can see the data behind the number, the conversation is short, and the payment moves faster.
How Emlid Reach fits your workflow and reduces construction profit loss
The fundamentals of the work don’t change. You move dirt, pour concrete, and put structures together. What changes is how much of that work you get paid for cleanly at the end.
Emlid Reach receivers handle exactly these jobs on a construction site: accurate enough to trust, rugged enough for the conditions, and simple enough that a crew can pick one up without a week of training. That lets your team run layouts, check grades, and document quantities themselves, and keep more of the margin you planned for.
That is the trade Garney was after—survey-grade accuracy at a price that puts receivers in more hands, instead of one expensive kit shared across the whole job.
“What this allows us to do is have a product that is still super high accuracy, but it’s more affordable—we can get it in more people’s hands.”
— Scott Brown, Construction Technology Manager, Garney
Here’s what that looks like on site: field engineers handling the routine layouts, material quantities you don’t have to guess at, and every invoice backed by real field data.
