GPMF AI Hackathon · The Finale | See the Money in the Model

​Here is the content cleanly formatted, organized, and ready to paste directly into your Luma event description field:

​🏛️ Guest Session — That Open Company

​The team behind the leading open-source BIM engine joins us to introduce That Open Engine and explore what you can build with it. An inspiring intro + hands-on exploration — then you build!

• ​Free & Open Source: JS/TS libraries — build and sell whatever you create.

• ​Runs Anywhere: Web, server (Node), desktop (Electron), and mobile.

• ​IFC in the Browser: Import, display, navigate, edit, and export BIM models.

• ​Built for Scale: Fragments renders millions of elements in seconds.

• ​2D + 3D: Floorplans, sections, dimensions, annotations, and DXF export.

• ​Plugs into Data: Power BI, SharePoint, Drive, plus GIS via Cesium/Mapbox.

​🎯 What to Build — Connect the Cost Model to the Building Model

​Your solution already knows where the money is going. Now make it visible. Pick a lane:

• ​Colour the Model by Cost Health: RAG / CPI per element or cost centre. Overruns light up red.

• ​Click an Element → Its Cost Story: BOQ item, budget, actual, variance, forecast.

• ​Instant Quantities → BOQ: Take quantities off the model to feed your estimates/norms.

• ​Zone Heatmap: Map cost centres onto the model using Zone/Area & Discipline data.

• ​2D Plans with Cost Markup: Generate plans/sections and annotate variances directly.

​🧩 The Toolkit — That Open Engine

​Everything is open source and documented. Explore tutorials, APIs, and live examples at docs.thatopen.com.

• ​engine_fragment (Open Source)

  • ​Store, display, navigate, and edit massive BIM data using a high-performance Three.js viewer.

• ​engine_components (Open Source)

  • ​Pre-made Three.js BIM tools: floorplan navigation, dimensions, postproduction, DXF export, viewpoints, and more.

• ​engine_ui-components (Open Source)

  • ​Ready-made web components for BIM UIs (panels, tables, toolbars) so you don't build the chrome from scratch.

• ​web-ifc (Open Source — already in our stack)

  • ​The IFC parser underneath it all, currently used in WakeCap's Observation Manager V2 and Portfolio Control Center.

​⏰ Agenda

​Here is the updated Run of the Day & Judging Criteria section formatted cleanly in Markdown, optimized to copy and paste straight into Luma:

​⏰ Run of the Day

• ​11:00 — Doors, Coffee & Settle at Tables (Khaled + Mentors)

  • ​Reconnect with your team and get set up.

• ​11:30 — Opening: Today's Mission (Khaled / Hassan)

  • ​Where we are, and today's shift: moving from tables and charts directly into the model.

• ​11:45 — 🏛️ That Open Company — Intro & Exploration (Guest · ~45 min)

  • ​Introduction to That Open Engine, what you can build with it, and a live look at the tools. Bring questions!

• ​12:30 — Lunch 🍽️

  • ​Fuel up — and talk through what you'll build.

• ​13:15 — Build & Deepen — Put Your Cost Model on the Building (Everyone · until 15:00)

  • ​One focused session: pick a lane above and make it real. Mentors and That Open team circulate. Don't break what already works.

• ​15:00 — 🎮 Kahoot! Trivia (Khaled · 30 min)

  • ​A fun round before pitches — construction, AI & QS themed. Bragging rights (and a small prize) for the winner.

• ​15:30 — 🎤 Final Presentations (Teams → Panel · 20 min each)

  • ​Show it: what you had → what you visualized → why a QS would use it.

• ​Post-Pitches — Panel Judging & Awards 🏆 (Hassan + Panel)

  • ​Judges confer, feedback to the room, and prizes for the top builds.

​⚖️ Official Judging Criteria — GPMF Scoring (100 Marks)

​We are scoring solutions against the official GPMF/PMA framework (Event Handbook Rev.1, §7.5) so your project is submission-ready.

​CriterionMarksWhat We're Looking ForBusiness Impact & Value Creation20Cost overruns avoided, money saved, better decisions. Clear, actionable recovery recommendations, and scalability beyond one project.Problem Relevance & Clarity15A real QS problem, sharply framed. Would a quantity surveyor actually reach for this?Technical Design & Architecture15Sound approach: confidence/uncertainty, risk as likelihood × impact, and an engineering mindset (smart AI delegation, evaluation strategy).Presentation & Communication15Clear story, no jargon: what you had → what you added → how you proved it.Team Collaboration & Engagement15Cross-disciplinary teamwork (devs + cost/PM + design) and engagement across sessions.Innovation & AI Application10How far you pushed it today (including builds on That Open Engine) and meaningful AI application.Prototype Quality & Demonstration10End-to-end functionality with accuracy proven against a baseline — not just claimed.

​Tie-Breakers: Business Impact → Prototype Quality → Problem Clarity.
