Auditing Systems in Construction and Trades

I was sitting down with a formwork company a few months back. Decent size operation, maybe 15 guys on the tools, couple of project managers. They'd been running the same way for about four years. And the thing is, it was working. Sort of. Until it wasn't.

They had a quoting spreadsheet that one of the PMs built back when they were doing half the volume. It had grown into this monster, formulas referencing other tabs, manual entries that nobody remembered why they were there. At that dollar value, at that many line items, human error is certainly a factor. Right?

So that's what a system audit actually is. It's not some corporate exercise where you bring in a consultant with a clipboard. It's sitting down and going, okay, where is stuff actually breaking? Where's the friction? Because it's always there. You just stop noticing it after a while.

The stuff people miss

Here's what I see over and over. A business grows, and the systems that got them from zero to where they are now, they're still running those systems. Nobody stopped to ask whether the process that worked for $500K in revenue still works at $2 million.

I was working with a trades business in Toowoomba, and their job scheduling was happening across three different places. Whiteboard in the office. Text messages to the crew. And a shared calendar that maybe two people actually looked at. The information was technically there, but it was scattered. So things got missed. Jobs overlapped. Guys turned up to sites without the right gear.

That's the mechanism, right? It's not that people are lazy or incompetent. It's that the system forces them to hold too much in their heads. And when you're flat out, stuff falls out of your head. That's just how it works.

Where to actually start

The temptation is to look at everything at once. Don't do that. You'll get overwhelmed and nothing will change.

Pick the thing that's causing the most pain right now. For a lot of construction businesses, that's one of three areas, how jobs get quoted, how information moves between the office and the field, or how you track what's actually been completed versus what was promised.

So Josie, she runs a civil construction outfit. When we first sat down, she was spending two hours every Friday afternoon reconciling timesheets against job schedules. Two hours. Every week. That's over a hundred hours a year on something that should basically run itself. And the thing is, she knew it was a problem. She'd known for months. But when you're busy as hell, you just keep doing the thing because stopping to fix it feels like it'll take longer than just pushing through.

What you're actually looking for

You're looking for gaps between how things are supposed to work and how they actually work. Because there's always a gap.

The quoting process says three days turnaround. Actual average is eight. Why? Because the estimator is waiting on supplier pricing that takes three days to come back, and nobody built that into the timeline.

The project handover from sales to delivery is supposed to include a site pack with all the specs. But half the time, the PM is chasing specs two weeks into the job because the pack was incomplete or the information changed after handover and nobody updated it.

That's the stuff you're auditing. Not the process document that says how it should work. The reality of how it does work. Talk to the people doing the actual work. Not just the managers, the guys on the tools, the admin staff, the people who deal with the consequences when something falls through.

Then what

Once you've found the problems (and you will find them) you've got to be realistic about what to fix first. Some things are going to have a massive impact and take two days to sort out. Others are going to require a complete system change that takes three months. Start with the two-day fix.

One of my clients emails me at least once a week with something new he's found. A process that could be better, a report that doesn't give him what he needs, a workflow that's got an unnecessary step in it. And that's actually the point, once you start looking, you don't stop. The audit isn't a one-off exercise. It's a way of operating.

The businesses that do well with this aren't the ones that did the biggest audit. They're the ones that built the habit of asking, is this still working? And being honest about the answer.

Most of them aren't honest about it until something goes wrong. A job runs over budget. A client complains. Someone quits because they're sick of fighting a broken system every day. By then you're fixing damage, not preventing it.

So yeah. Start with the pain. Talk to your people. Look at what's actually happening versus what's supposed to happen. And fix the easy stuff first.

That's probably where the conversation needs to start.
