The solution

One assistant, across
the whole build.

Learns

Soterra learns from its construction knowledge, your company's history and every project's documents. It remembers what happened on past jobs, so nothing is lost between projects.

Guides

Builds the QA checks that matter on this job and catches issues before work starts. It also drafts RFIs, reviews your H&S, programme and scopes, and answers any question cited to the source.

Prevents

Everything it does has one aim. The right knowledge reaches the site exactly when it's needed, so issues are caught before it's too late.

Potential impact · model on a $10M project

On a $10 million project, Soterra could prevent around $300,000 in direct rework.

rework exposure $10M × ~10% = $1,000,000
from recurring issues ~60% = $600,000
eliminate half of those → $300,000 saved / project

An example before the job

The wrong glass,
halfway in.

The plans and the façade PS1 didn't line up. The window contractor installed the wrong glazing off the architectural spec, and half of it was in before a façade inspection caught it.
▸ Soterra reads every document together, and flags the conflict before it's installed.

Before we order the windows, can you check the drawings and PS1s for any clashes?
Reading the whole set…📐 From your plans

I read the whole set. One clash worth an RFI: the window schedule calls for 6.38mm laminated glass for the Level 3 windows, but the façade PS1 is designed on 10.38mm for the same units. The documents disagree, so I'd raise an RFI before anything's ordered. Want me to draft it?

An example during the job

Same mistake.
Next site.

Site 1

TV nogs hidden in a corner of the plan. Missed. The floors below were already lined when the architect caught it, and it went in his inspection report.

Site 2

Same detail, missed again, and walls were cut open. The knowledge was already there, it just never made it to the next site.

▸ With Soterra, the knowledge carries from one site to the next, so the same mistakes stop repeating. In our research, more than 60% of issues were recurring.

Before we line the walls on Level 2, build me the pre-line check.
Building the check…📐 From your plans

No open CIs are relevant to the Level 2 linings. From your own history: the architect flagged missing TV nogs behind the lining at 42 Manuka Rd, your last job, so they're first on the list. The TV points are on the electrical plan. Get them in and marked before the GIB goes on.

Defensibility

Our operating edge.

Company memory

Every job makes the next one smarter.

NZ knowledge

Code, councils and manufacturer manuals, with permission.

20 years on site, built in

It knows where the mistakes hide, because we've made them ourselves.

Why now: Proportionate liability is coming, and main contractors will carry more responsibility. Other tools digitise a checklist that might not even fit the site. Soterra writes it for you, from the plans, your history and the Code.
