One interactive model you can actually walk through. I build 4D / 5D simulations, digital twins and real-time walkthrough applications that turn fragmented model, schedule and cost data into a single, decision-ready source of truth — from early design through construction, handover and facility management.
Every project already has the data. What it usually lacks is a way for people to see it, question it and agree on it — together, before it costs money.
Construction sequencing driven by logic, zones and design intent — not by colouring in a finished programme.
Real-time, navigable project environments that stay useful long after handover.
Game-engine experiences that let people explore a project instead of being presented to.

I'm a 4D simulation professional working at the intersection of architectural design, construction planning, real-time visualisation and technical development. My work focuses on integrating fragmented AECO project data into a central, interactive source of truth — allowing stakeholders to understand, explore and make decisions without relying on assumptions or disconnected schedules.
That means sitting between the people who rarely share a screen: the design team, the planner, the cost manager and the site. When those four views are stitched into one model that moves through time, arguments turn into decisions and decisions get made earlier — when they are still cheap.
“4D and 5D should start on day one of a project — not after problems appear. When time, cost and design intelligence are embedded early, projects gain clarity, alignment and predictability across all phases.” — Amr Yassin
Counttable is what happens when the work stops being a service and becomes a system: design, construction, cost, time and intelligence connected into one living workflow. I founded it to close the gap I kept meeting on projects — the one between a model that is technically correct and a team that actually understands it.
Design. Build. Understand. Everything.
Skipping any one of them is why most 4D ends up as an animation nobody uses.
Architectural intent and constructability first. Before anything is sequenced I need to know what the building is trying to be, and where it will fight the people building it.
Align model, time and cost logic. Naming, zoning, WBS and parameter discipline — the unglamorous layer that decides whether everything downstream is trustworthy or theatre.
Convert complexity into readable systems. Colour, hierarchy and time used deliberately, so a director and a foreman can read the same screen and reach the same conclusion.
Enable exploration, not passive viewing. People trust what they can interrogate — so the output is something to click through and challenge, not a video to sit through.
Extend value into FM and operations. The model that helped you build it should be the model that helps you run it for the next thirty years.
Whether you need a person on the team, a system delivered, or a team taught to do it themselves.
Full-time or embedded inside your delivery team, owning digital delivery from standards through to handover.
A defined scope, delivered end to end — from kickoff data audit to the final interactive handover.
For construction teams and individuals who want the capability in-house rather than outsourced forever.
A cross-section of sequencing, twin and real-time work — from construction logic to the operational picture.

To redefine how AECO projects are planned, communicated and operated — by making 4D and 5D intelligence the central nervous system of a project, from design to operation.
To design integrated 4D simulations, digital twins and interactive systems that convert complex project data into clear, visual and actionable information — supporting confident decisions across every phase.
A role, a project, a team that needs the capability — or a conversation about Counttable. I answer everything.
