Good QA documentation is an investment nobody notices, until they need it.

Tony’s seen both sides of this: contractors who treat documentation as a box to tick, and contractors who treat it as a genuine record that protects everyone involved.

The second group takes longer at the time. It's also the group whose documentation actually holds up when a dispute, defect, or question surfaces well after the project's complete.

That's the entire point of doing it properly the first time.

Applying membrane at scale demands a level of consistency that not every roofing contractor is set up to deliver.

As a trusted, approved applicator for leading torch-on membrane suppliers, Sansom brings both Mini Macaden technology, capable of covering upwards of 700m² per machine per day, and the quality assurance process needed to get every roof right the first time, not just the fast one.

That includes Electric Field Vector Mapping testing, carried out with ILD New Zealand, to check for mechanical damage or water ingress points before handover.

A building outlives the people who worked on it. Its paperwork shouldn't disappear with them.

Staff turn over, subcontractors move on to other projects, and site managers who once knew every detail of a job aren't always reachable when a question comes up years later.

What's left behind on paper is often the only thing that still speaks for the work that was done.

That's less about protecting against disputes and more about giving whoever manages the building next, a facilities team, a new owner, a different contractor entirely, something solid to work from instead of starting again from scratch.

It's a detail that rarely factors into who wins a tender. It matters a great deal to whoever's left managing the building afterwards.

Tunnels move slower and cost more for a reason, and it's not inefficiency.

Tunnel projects typically involve significant government oversight and funding, and as with most major infrastructure, that scrutiny scales up alongside the project itself.

As a tunnel grows in scale, so do the checks and balances built around it, more approval stages, more scrutiny, more parties accountable for the outcome.

That's exactly why the largest tunnel projects tend to move slower and cost more. It isn't a flaw in the process. It's the scrutiny that scale demands.

A hundred unreviewed photos in a folder isn't quality assurance. It's just a folder.

According to Tony Murphy, most of what passes for quality assurance on a construction site is a hundred photos dumped into a file and sent off, with nobody stopping to check what's actually in them.

Some of those photos are irrelevant.

Real QA means someone reviews what's been captured before it ever reaches the client, not after.

Tanking is officially underway on our newest high-rise project.

256 Queen Street, a 33 level tower going up with ICON for Precinct Properties in Auckland's C*D. We've been involved since the early design stage, and this is where it all starts, get the waterproofing right at the base, and everything above it depends on it.

Here's an early progress look: https://www.youtube.com/watch?si=DpCNCWboj8qYjbOq&v=0vP485A_-e8&feature=youtu.be

Most QA issues are only revealed when it's too late.

They start in someone's inbox, months later, when a client asks a question nobody on the original job can answer with confidence.

That's usually the moment it becomes clear whether documentation was ever actually reviewed, or just collected.

A folder of unfiltered photos might satisfy a checklist at handover, but it rarely holds up when someone's trying to reconstruct what actually happened on a specific day.

Sansom's tiered approval process exists for exactly that scenario, not the handover, the follow-up.

Every layer of review, from site capture to project manager sign-off, is what makes the documentation something a client can actually rely on later, not just something they were handed once.

A façade takes on more structural risk than most people realise, especially at the joints.

Seismic joints demand a level of precision that not every façade contractor is set up to deliver.

As specialists who have been completing this work since the company's earliest days, Sansom brings deep technical expertise in precast panel installation and drained joint, baffle, and air seal systems for significant multi-storey buildings.

That includes documenting every stage through CONQA, giving architects, main contractors, and consultants a clear, verifiable record that the façade will perform as designed.

Waterproofing typically makes up just 2 to 3% of a building's total cost.

Water ingress is behind roughly 80% of the issues that show up during or after construction.

That gap is worth sitting with.

A relatively small portion of the budget is responsible for the outcome of most defects that follow, whether they surface mid-build or years after handover.

Quality assurance testing adds only around 2% on top of standard waterproofing costs, often less on larger roofs, in exchange for an evidential record that the system was actually sound at handover.

Set against an 80% failure rate tied to the same cause, it's a small premium for a significant reduction in risk.

Over 50 years in the industry has taught us this: cheap fixes are rarely cheap.

They cost less upfront, but they tend to cost a lot more once you factor in the rework, the disruption, and doing the whole job again a few years later. We build for the long run instead, even when it means a bigger job on day one.
