Most BIM models show a home in its pristine newly-completed state — yet real homes change over time. Materials weather, vegetation grows, and certain areas require periodic maintenance. Time-Based BIM simulates these changes so homeowners can make decisions with full long-term visibility.
Four Dimensions of Time-Based BIM
Dimension 1: Material Aging Simulation — Simulates how materials weather over time. Untreated teak turns grey within 2–3 years. Natural stone tiles have porosity requiring sealing every 2–3 years. Metals in Bangkok’s high-humidity, high-pollution climate may begin corroding within 5–7 years without appropriate protective treatment. BIM visualizes actual material condition at 5, 10, and 20 years ahead.
Dimension 2: Vegetation Growth Modeling — Garden plants and Living Walls change significantly over time. BIM simulates how large trees grow and which areas they will shade in 10 years, informing decisions about which tree species to plant near the home versus at a distance. Some tree root systems can damage foundations or plumbing pipes at maturity.
Dimension 3: Maintenance Cycle Planning — BIM generates a Maintenance Timeline showing which areas require attention at which intervals: exterior painting every 5–7 years, roof maintenance every 10–15 years, bathroom Sealant replacement every 5 years. Homeowners can plan maintenance budgets accurately in advance.
Dimension 4: Structural Movement Simulation — Bangkok experiences land subsidence averaging 1–2 cm per year in certain areas. BIM combined with site-specific Subsidence Rate data simulates structural impact over 20–30 years, enabling foundation design that accommodates differential settlement.
The Value of Long-Term Visualization
Materials that photograph beautifully but require intensive maintenance or weather rapidly can become a significant burden within 5 years. Time-Based BIM enables homeowners to compare Life-Cycle Cost across material options, making the most cost-effective long-term selection.
