Behaviour architecture
Revising agent decisions, target commitment, retry states, queue lifecycles, and task-to-route translation.
Team product / Social digital twin
TectoTrack
A living simulation environment for studying how people move, choose, wait, and experience complex buildings.
Question
How can a building model include people as active, uncertain participants rather than static occupancy values?
Response
TectoTrack combines a digital building environment with agent-level decisions, routing, queues, services, accessibility rules, and reportable simulation data.
Agent-level
behaviour and task logic
BIM → runtime
repeatable model pipeline
Live system
routing, queues and services
Decision-ready
spatial and operational evidence
01
System, not a scene
TectoTrack is not a rendered copy of a building. Its digital environment stays connected to a simulation graph, Function Objects, agent tasks, vertical transportation, service queues, and analytical outputs.
The central design problem is behavioural: an agent must perceive available choices, commit to a destination, move through multiple levels, react to congestion, and still remain explainable when something goes wrong.

My contribution
Routing & accessibility
Multi-level paths, stairs, escalators and elevators, including wheelchair-compatible reachability.
BIM-to-simulation
Helping structure the FBX and metadata pipeline so design models enter Unity with consistent coordinates and semantics.
Evidence & documentation
Turning debugging history into architecture decisions, invariants, test gates, and maintainable technical documentation.

A behavioural loop
-
01
Read context
The agent receives a persona, task sequence, location, constraints, and available services.
-
02
Choose & commit
The decision layer selects a reachable target without confusing intention with intermediate route objects.
-
03
Move & negotiate
Navigation, queues, level transitions, capacity, and other agents continuously shape the path.
-
04
Record consequences
Movement, waiting, density, service use, and failure states become analysable evidence.
04
Engineering underneath
Queue as a physical system
Explicit FIFO order, slot ownership, vacancy propagation, overflow policy, and collision-safe movement.
Simulation before spectacle
A persistent simulation shell is separated from visual chunks to control memory without changing agent logic.
Failure is observable
Incomplete routes, stale callbacks, unreachable services, and state conflicts are documented rather than silently hidden.
Scale through contracts
Coordinate, lifecycle, readiness, and ownership contracts keep a large collaborative codebase understandable.
05
What it proves — and what it does not
Current position
The platform demonstrates a substantial, working simulation architecture for complex facilities. Behavioural realism still requires calibration against observed people and project-specific data; a convincing animation alone is not validation.
