BREEAM Rating Simulator
BREEAM (Building Research Establishment Environmental Assessment Method) rates buildings on sustainability. Adjust the sliders for your imaginary building project and watch your overall rating change in real time.
OVERALL SCORE
Sectoral Variations
Different sectors = different drivers. A hospital client and a hotel developer want very different things. Click each sector to explore what matters most.
Site Safety Scenario
A site worker is about to start excavation work on a new foundation trench. You notice they have no shoring in place, are not wearing PPE (no hard hat, no high-vis), and there is no permit-to-work visible. You are the Site Supervisor. The trench is over 1.2m deep.
The Crossrail Case Study
The Elizabeth Line — Britain's biggest construction project
Crossrail is the textbook case study for every stage you've learned this week. Design challenges, pre-construction planning, procurement complexity, megaproject construction, and a famous overrun on both time and budget. Every concept in the module is visible here in real life.
✏️ STAGE 1 — Design Challenges
- Brownfield site: Threading 13 miles of new tunnel beneath one of the world's oldest cities — under the Thames, beside live tube lines, past Victorian foundations.
- 10 new stations designed by different architects — Bond Street, Tottenham Court Road, Liverpool Street, Whitechapel, Canary Wharf, Farringdon, Paddington, Custom House, Woolwich, Abbey Wood.
- BIM integration: First UK megaproject to use a fully integrated 3D model across every discipline — civils, MEP, signalling.
- BREEAM: The project pioneered the use of BREEAM for underground stations — a new benchmark for the industry.
📋 STAGE 2 — Pre-Construction
- Procurement: Used a mix of Management Contracting and Construction Management routes — 36 main works contracts, each with its own tender.
- Geotechnical surveys: London clay, sands, gravels, wet chalk under the Thames — different soil = different TBM type.
- Contracts: NEC-family contracts used throughout, with target-cost pain/gain mechanisms.
- Risk planning: Live tube tunnels within metres of works; vibration, settlement and noise monitored continuously.
🏗️ STAGE 3 — Construction
- 8 TBMs bored 42 km of 6.2m-diameter tunnels: 6 Earth Pressure Balance machines for clay, 2 Slurry machines for wet chalk under the Thames.
- Tunnel lining: Over 220,000 concrete segments, each weighing 3.4 tonnes.
- One TBM dug 72m in a single day — a record-breaking pace.
- Mined stations: Bond Street, Tottenham Court Road, Liverpool Street and Whitechapel were excavated below ground rather than dug from the surface.
🔑 STAGE 4 — Handover & Lessons
- Opened May 2022 — 3.5 years late vs. the original December 2018 target.
- Original budget: £14.8bn (2010). Final cost: £18.8bn — a 28% overrun.
- Systems integration failure: The biggest cause of delay wasn't civil engineering — it was integrating three different signalling systems.
- Economic benefit: Estimated £42bn boost to the UK economy. Supports 55,000 new homes.
🛠️ The Tunnel Boring Machines
Each TBM was 148m long — about the length of 14 London buses end-to-end — and weighed 980 tonnes. By tradition every British TBM is given a female name. Click each one:
Budget Balancer
You are the Quantity Surveyor on a £10 million commercial office project (a scaled-down Crossrail station, if you like). Allocate your budget across the 8 categories below. Each category has a minimum and recommended spend — go too low and you'll fail; go too high overall and you're over budget.
Memory Match Game
Flip two cards at a time to match construction icons with their terms. All 12 pairs must be found. Track your moves — lower is better. Each match earns 5 XP, perfect game bonus +20.
Term Builder
Guess the construction term letter-by-letter. Each wrong guess builds the crane. Get the word before the crane is complete to earn 15 XP.
Timeline Sort Challenge
Drag the 6 Crossrail milestones from the bank into the correct chronological order. When you're confident, hit "Check Order" — correct slots glow green, wrong ones glow red. Perfect order = 30 XP.
