Why does every new labourer get told the safety rules differently?
Because in most demolition businesses the asbestos checks, the strip-out sequence and the site safety rules exist only in the owner's or the site supervisor's head, not on paper. Each labourer or machine operator hears a slightly different version depending on who briefs them that morning, and there is nothing written down to check their work against once the crew starts moving.
A demolition contractor moving onto a new site carries a string of steps that have to happen in order. The asbestos register gets checked before anything structural is touched, the permit and the neighbour notice get logged with the council, dust and site safety measures go up before the excavator starts, and salvage gets pulled before the rest goes to the bin or the truck for tipping. When that sequence lives in one person's memory, a new labourer or a stretched site supervisor can skip a step without anyone noticing, until it surfaces later as a missed notice, a licensing breach, or a complaint from a neighbour.
Why does a demolition quote depend on who in the office wrote it?
Because without a documented way of pricing a strip-out or removal job, every quote becomes a guess based on gut feel rather than a repeatable system. One person might price the excavator hours generously, another might forget hazardous waste disposal or leave salvage value off the sheet entirely, and the margins swing from job to job for no reason the owner can point to.
A demolition contractor who quotes a soft strip, a house knockdown or a commercial strip-out by feel, rather than item by item for labour, machinery, tipping, recycling, hazardous waste and salvage, is really guessing at the one number that matters most on every job: the gross profit margin. That number should be checked at the moment the quote is built, not discovered weeks later when the bills for tipping and disposal come in and the job looks thinner than it should have.
What should a demolition contractor build and test before handing a job to the crew?
Build the system on yourself first. Walk through the strip-out sequence, the dust control routine or the asbestos licence checks as the actual steps you follow on site, write them down in the order they happen, then hand that document to the crew member who will run the job next time.
If you test the system on your own work before anyone else runs it, you know it holds up before a labourer's safety, a neighbour's complaint, or your licence depends on it. When a labourer or a machine operator gets something wrong on site, the problem is rarely the person. It is usually a step that was never written down for them to follow, which means documented roles and steps show you exactly where the training gap sits, rather than leaving you guessing who to blame.
What changes when AI agents take on the office work in a demolition business?
AI agents, software that does a piece of office work the way you would do it, with your own prices, wording and rules, can take on much of the paperwork sitting around every demolition job: logging the permit and neighbour notice, tracking asbestos licence and register checks, and building the item by item quote from labour, machinery, tipping and salvage.
That changes where your time and your site supervisor's time actually go. Instead of chasing paperwork after hours or repeating the same safety brief to every new hire, the AI agents hold the sequence and the pricing logic consistently, and the people in the business spend more of their time on the site, the crew, and the client standing in front of the house or the commercial fit-out, not less.
Should a demolition contractor rent software or own systems built on their own jobs?
A demolition contractor can choose to own systems built on their own jobs, quotes and crew, shaped around how demolition work actually runs, rather than renting a generic trade app built for a plumber or a builder. Some off the shelf tools still suit, a GPS tracker for the truck and excavator fleet, a basic invoicing package, and the data first approach shows which of those are worth keeping.
The difference is what the system is built around. A rented app treats a strip-out quote the same way it treats a plumbing call out. A system built on a demolition contractor's own data treats the asbestos register, the permit, the tipping and disposal costs and the salvage value as the separate line items they actually are, because that is how the job and the margin really work.
How does Data First Coaching approach this?
Data First Coaching starts from the demolition contractor's own job and quote data, not from a generic checklist, because that is where the real gap between the asbestos register, the strip-out sequence and what the crew actually does on site shows up first. Greg Allan has a line for this: “it's not my people, it's my systems”. The Trade Business Intelligence reads that data alongside years of coaching trade businesses to find exactly where the method breaks down, whether that is quoting, licensing checks or the sequence a crew follows on site. The how, building and testing those systems, is worked through inside the Academy, with members, because it is for owners who are open minded, innovative and willing to share what they learn with the rest.
