Building Safety Act Compliance Software
The Building Safety Act asks every dutyholder the same question: prove it. BrieXO builds the proof as the work happens — site records, photo evidence, competence records, and decision trails anchored to the building itself. One tool, one record. No more spreadsheets.

Three demands. One answer.
The competence regime asks you to prove your people. Clients and tenders ask you to prove your carbon. The golden thread asks you to prove the building. Different regulations, same demand: evidence that stands up.
A record scattered across Excel trackers, email chains, WhatsApp threads, and folder graveyards cannot answer that demand — least of all at handover, years after the people who did the work have moved on. BrieXO takes the opposite approach: one living record, built as the work happens, anchored to the building.
What the Act Actually Demands of Dutyholders
The Building Safety Act 2022 restructured accountability across design and construction. Four duties do most of the work — and all four run on evidence.
The dutyholder regime
Clients, principal designers, principal contractors — and every designer and contractor on the job — carry named legal duties to plan, manage, and monitor their work so it complies with building regulations, and to cooperate and share information with the other dutyholders. Accountability is personal and organisational, not something you can subcontract away.
The golden thread
For higher-risk buildings, dutyholders must create and maintain accurate, up-to-date building information — stored digitally and securely, accessible to those who need it, and handed over to the accountable person at completion. The thread runs from design through construction into occupation: a single source of truth about the building and how it stays safe.
Gateways 2 and 3
Higher-risk building work needs building control approval from the Building Safety Regulator before construction starts (Gateway 2) and a completion certificate before occupation (Gateway 3). Both are hard stops — the project does not proceed until the regulator is satisfied — and both turn on the quality and completeness of the evidence submitted.
Competence duties
Individuals must have the skills, knowledge, experience, and behaviours their role requires; organisations must have the capability. Dutyholders must not appoint anyone who does not — which means competence has to be demonstrable and current, not asserted. Certificates in a drawer do not answer the question; records that connect people to the work they did can.
What counts as a higher-risk building?
In England, a higher-risk building is at least 18 metres tall or has at least seven storeys, and contains at least two residential units. Hospitals and care homes meeting the height threshold are also in scope during design and construction. Even where a building falls outside the definition, many clients now expect golden-thread-quality evidence as standard.
This is a general summary of the regime, not legal advice on how it applies to your projects.
One Living Record Answers Each Duty
BrieXO does not add a compliance layer on top of the work. It makes the work itself produce the record — so the evidence exists because the job was done, not because someone reconstructed it afterwards.
Evidence as the work happens
Daily site records, QA/ITP checks, RAMS gates, and photo evidence captured on the day, by the people doing the work — timestamped, attributed, and linked to the task they describe. Handover stops being an archaeology project.
Decision trails that survive
Every approval, change, and supersession lands in a tamper-evident, hash-chained audit ledger. Who decided, when, and why stays answerable after staff turnover, after the project team disbands, and years into occupation — with signed evidence exports when a reviewer asks.
Competence you can show
XO Comp holds role frameworks, verified competence evidence, training plans, CPD, and eligibility signals — connected to the labour records of who was on site. When you appoint someone, there is a record behind the decision; when someone asks what qualified an operative, the answer is one query away.
Anchored to the building
Evidence attaches to a spatial model of the asset — Building, Floor, Elevation, Location, Element — not to a folder named "Final v2 USE THIS ONE". The golden thread is supposed to describe a building; in BrieXO, the record is organised the way the building is.
Ask the question the regulator will ask
Because every record is anchored to the building and chained in the ledger, EXOH can answer a dutyholder question with the location and the decision trail behind it — not a list of files that might be relevant.
Every answer traces back to signed, timestamped records. You can defend it, not just believe it.
"Who installed the cavity barriers on level 9 — and what qualified them to do it?"
- Riverside Tower > Level 9 > Elevation B > Shaft wall > Cavity barrier CB-09-14
- Site record and photo evidence from the day of installation, with the operatives named
- Their competence records, verified and current on the install date
- The approved detail change behind the install, with approver, date, and hash
