From go-live to the old frustrations being gone
"Plexa is a one-stop shop. Finance, plans, 3D models, drawings, safety systems, sign in and sign out. It's all in one."

Project Coordinator
Three platforms, and nothing between them
DeMartini Fletcher were growing. Bigger residential developments, commercial fitouts running across several sites at once, and a portfolio of existing assets underneath all of it. The systems holding that together had not grown with them.
Safety lived on one platform, project management on another, programming on a third. None of them spoke to each other, and the space between them was filled with spreadsheets, Microsoft Project and paper. Things got lost, and at the pace the team worked they were "constantly picking up the pieces", says Project Coordinator Dyson Black.
For Brett Muller, who runs property for the business and has spent more than 30 years in construction and fitouts, it showed up as a loss of control. He was accountable for sites he could not stand on. "Before Plexa we didn't have much control," he says. "It was all very manual and very labour-intensive." The cost of that was not abstract to him: "inefficiency in this game costs money."
"The AI lets me jump on the chat and ask what's happening on this site, or that site, and I get it instantly. I'm not going off to find a report."

Two days, a pen, and 88 apartments
Ask Dyson when he knew it had to change and he does not describe a strategy session. He describes a defect walk.
A residential job in its final stages. Every apartment with a checklist taped up inside it. To find out what was still outstanding, somebody walked the building, all 88 of them, ticking boxes by hand. Two days for a single pass. At the end of it the trades were still marking their own work off on paper that nobody at a desk could see.
The information existed. It was just unreachable by anyone who needed to act on it.
Chosen on how fast their own people took to it
DeMartini Fletcher looked at other all-in-one platforms first. Two things decided it, and neither was a feature list.
The first was adoption. On a construction site, software has to work for the person who loves systems and the person who resents them, on the same day. Compared with the alternatives, Brett says, Plexa was "easier and a lot more user-friendly", and the site staff and office staff "picked it up very quickly".
The second was how the rollout ran. The team came up from Sydney to Brisbane, held weekly sessions through the implementation, worked at both the office and the site, and trained the field and the office separately because the two groups need different things. "Each step of the way there was a plan," says Brett, "and it was executed."
"I've got visibility across the entire project now, at the push of a button. I can see exactly what I want when I want it, and I'm not having to go to site, go to staff, make phone calls."

One system, then an AI layer on top of it
They put project and document management, site and HSEQ, and finance and budget onto Plexa. In practice: drawing and document control with workflows, site diaries, safety, site access and attendance by QR code, defects from a phone, plan markups, 3D models, inspections, tasks, meetings, and live budget against committed cost. One system holding what three used to hold badly.
The AI was not what they bought. It arrived on top of a platform they were already running, and it only worked because the data underneath it was finally in one place. Brett's job is knowing where things stand, which used to mean going and getting a report, or going and getting a person. Now he asks. He has also connected Plexa to the tools he already uses through the MCP connector, so his project data answers questions from outside Plexa entirely: "so we can use ChatGPT or Claude to get the information we want when we want it."
In the field
The two-day defect walk became a photo. A defect is raised where it is spotted, by whoever spots it, and it reaches the trade who has to fix it before that person has walked to the next room. If they are on site tomorrow, it gets fixed tomorrow, rather than waiting for the next pass with a clipboard.
The same pattern runs up the building. QR codes on site, phones and iPads on the steel and formwork decks, inspections closed out in front of the engineer who raised them. "They're small time-saving moments," says Dyson, "but they compile. It saves real time and real money on each deck, on each stage of the job."
Plan markups now stay with the plan, floor to floor, which removes a whole class of waiting: "We're not sending it off and waiting for someone to come back with an answer. We pick it up and we run."
"Safety on one platform, project management on another, programming on another. Nothing talked to each other. It was clunky, things got lost, and at the pace we work at we were constantly picking up the pieces."
Dyson Black
Project Coordinator
In the week, the office and the business
Tasks that took Dyson an hour or two now take thirty minutes, and that time goes back into the work a coordinator is actually there to do. With the programme, the trades and the defects in one system, the job stops being about chasing information and starts being about keeping the building moving. "No apartment should be sitting empty with no trades in it."
In the office, budget position is live. Nobody reconciles AP against a separate finance system to find out where the job stands: at 30, 40, 50 percent through, Dyson says, "we can see where we should be and where we actually are." Brett has the same visibility across everything else, "at the push of a button", including who is on site, when, and what the site diaries say.
It reached both halves of the workforce, which is where most rollouts fail. Some of their people are hesitant about technology and others are gung-ho, and Brett's verdict is that Plexa "caters for both". The impact, he says, "was almost immediate": savings in labour, and overheads that "have come right down" since they went live.
"My recommendation is definitely give Plexa a chance. Have that first conversation, you won't be disappointed."
