Toby McCosker on Managing 500+ Projects Without Losing His Mind

When Scale Meets Sanity

Most people think managing a handful of construction projects is tough. Try managing over 500. That’s not a typo. Across my career, I’ve overseen hundreds of builds—residential, commercial, public—and somehow, I’m still here. Still sane. Still building.

This isn’t a flex. It’s survival. Because when the number of projects starts climbing, the margin for error shrinks. One missed call, one bad estimate, one poor hire—any of these can ripple through your business like a wrecking ball. But with the right mindset, systems, and leadership, chaos doesn’t have to be your baseline.

From One Site to Hundreds

I started out with a toolbelt and a dream. Back then, one job felt like the world. As the business grew, so did the complexity. And soon I was managing dozens—then hundreds—of sites, trades, and timelines all at once.

Let me tell you: there’s no secret sauce. No magic app or hack that makes this easy. What it takes is brutal prioritization, relentless systems thinking, and absolute clarity in communication. You don’t get the luxury of being reactive when you're operating at this scale. You need to lead, or you’ll drown.

I’m Toby McCosker, and I didn’t get here by playing it safe. I got here by building lean teams, hiring for character, and learning how to trust others without handing over the wheel blindly.

Systems Save Sanity

The only way to manage 500+ projects without losing your mind is to stop managing projects—and start managing systems.

• Project tracking tools don’t just track—they forecast.

• Checklists aren’t for rookies—they’re for pros who don’t miss.

• Daily briefings become non-negotiable.

• Delegation stops being a leadership style and becomes your oxygen.

You have to build a culture that runs without you micromanaging it. That takes time, training, and trust—but once it’s in place, it frees you to lead strategically instead of putting out fires all day.

Leadership at Scale

What changes when you go from 5 jobs to 500? Everything. People don’t just look to you for decisions—they look to you for confidence. For certainty. For accountability when things go wrong.

I’ve had days where five different emergencies landed at once. And I’ve learned the hard way: you can’t give what you don’t protect. If you don’t protect your time, your headspace, your sleep—you’ll burn out and take everyone with you.

So I lead by example. I show up, but I also step back when I need to. I don’t pretend I can do it all—I’ve learned to build teams that can move without me hovering over every step.

You Need Grit, Not Just Growth

Managing hundreds of projects looks impressive on paper. But behind the scenes, it’s a test of character. You have to stay sharp under pressure, make calls quickly, and never let your ego get ahead of your operations.

I’ve made mistakes. I’ve had projects run over, budgets blow out, and timelines stretch. But I’ve owned it, learned from it, and kept moving. Resilience isn’t just a buzzword—it’s your daily uniform.

Conclusion: Lead Bigger by Thinking Smaller

Here’s what I’ve learned: you manage 500 projects the same way you manage one. With attention, discipline, and heart. The difference is, you scale the process—not the pressure.

I’m Toby McCosker. I’ve built a business that spans hundreds of sites without losing sight of what matters. And I’m proof that with the right systems, the right people, and the right mindset, you don’t have to choose between scale and sanity.
