UNIVERSEL · SENTINEL · the nervous system of the building
To watch in silence over a building that never sleeps, and to act before what is going wrong becomes serious.
Our role
A delivered building has hundreds of physical sub-systems: the structure that breathes under the wind, the air that the occupants share, the water that flows through the risers, the energy that runs through the meters, the fire-safety system that waits to serve, the lifts that move up and down, the façade that expands and contracts, the network that talks to every sensor. We listen to all of that down to the millisecond. We detect what drifts away from the norm. We decide without asking when life or compliance require it. And we are accountable to the operator, the insurer, the regulator, the court if it ever comes to that.
The latencies that matter
When an earthquake hits, the P-wave arrives ahead of the destructive S-wave. Between the two, we have two seconds to cut the lifts and pressurise the stairwells. When an infrared camera sees smoke, we have five seconds to fire the smoke-extraction system in the right zone, not in every zone. When an operator looks at her dashboard, she will not tolerate more than five hundred milliseconds between her click and the response. These thresholds are not marketing targets. They are measured by chaos-engineering scripts before every production release. If one is red, the build does not ship.
The conversation between the three platforms
The building is born inside UNIVERSEL-IGH, which draws it down to the smallest IfcSpace. The day of the handover, the frozen IFC arrives at our door. We read its Pset_SentinelAnchors to learn where each sensor lives, and we plug ourselves in. Meanwhile, NEXUS-URBAN watches the street outside. And the conversation runs in every direction: when we detect a structural crack, we open a BCF topic in UNIVERSEL so the structural engineer can see the exact spot in 3D. When NEXUS-URBAN flags an urban event four hundred metres away gathering thirty thousand people, we adjust our security thresholds. And when, after six months of operation, we observe that an acoustic wall measures thirty-eight decibels instead of forty-five, we send the observation back to UNIVERSEL, which records it on the model, and the annotation stays there for future refurbishments.
Proof, not promise
Every legal event — a fire, an intrusion, a lift failure with injury, a cyber breach — is cryptographically signed, hash-chained with SHA-256 and ed25519, exportable as PDF/A-3 and JSON-LD for judicial review. Every claim pack is assembled automatically and signed eIDAS qualified. If a loss occurs at three in the morning, the case file is ready before the insurer finishes his coffee. If someone attempts a fraudulent claim, the chain of custody dismantles it with a precision no one can dispute.
Compliance, wired in from the inside
NFPA 72 for fire alarms. ISO 22301 for business continuity. ISO 27001 and IEC 62443 for OT cybersecurity. IEC 61508 SIL 2 for safety-critical loops. ASHRAE 62.1 and EN 16798 for indoor air quality. Eurocode 8 Annex F for structural seismic monitoring. GDPR for cameras and occupancy counting, with a mandatory DPIA. These norms are not a dossier we assemble the night before an audit. They are wired into the data model, into the Rego policies, into the signing chain. When the auditor walks in, we open an endpoint and the compliance matrix presents itself, line by line, proof by proof.
Zurita Tower, our virtual reference building
Zurita Tower is our virtual reference building. The building itself does not exist, but every datum that animates it is a rigorous simulation, derived from real supertall standards: five hundred and twenty-five metres, one hundred and eight storeys, Y-shape twisted geometry, nine hundred and twenty-five zones, fourteen thousand eight hundred and seventy sensors anchored on their IfcSpace. Its model lives at UNIVERSEL-IGH, its operational runtime lives here with us, its urban context lives at NEXUS-URBAN. It lets us demonstrate the seismic cascade, NFPA-zoned smoke extraction, the eIDAS-signed claim pack, without depending on a live project.
Who we are
A team that believes a delivered building should never be left alone. That a broken seismic sensor is not an acceptable detail, not even on a Tuesday at three in the morning. That an occupant's safety is not a tradable item. That the insurer has the right to know what happened, and the owner has the right to be able to prove it. We write software so that these rights are something more than a clause on paper, reread after the disaster.
Our commitment
Zero cosmetic false alerts. When SENTINEL wakes an operator at two in the morning, it is because something is happening. Zero data loss: every sensor measurement is written to time-series storage before the network acknowledges it, and buffered seven days on the edge gateway if the link drops. Zero broken chain of custody: every legal event is HSM-signed. OT security by default: the sensor network is isolated from IT, and every command sent to an actuator passes through an authenticated, audited broker.
