Study Notes
Digital Technologies in Design
- Digital technologies are transforming the design process, showing potential to significantly reduce project costs and improve efficiency.
- The average lifecycle cost of a project can potentially be reduced by almost 20% with new technologies.
- Digitization could translate into $0.5 trillion in operational phase savings, and up to $1.2 trillion in design and construction phase savings.
- Digital technologies are not equally implemented across sectors. Sectors like ICT, media, and finance/insurance have higher digitization levels compared to healthcare, construction, and hospitality.
- Current levels of digitization in different sectors vary considerably.
Lackluster Performance in Construction Projects
- Construction projects frequently experience significant overruns in capital expenditure, often exceeding the originally quoted amount.
- The average delay beyond the original schedule for mining projects is 20 months.
- Infrastructure projects tend to have an average overrun of 80%.
- Oil and gas projects commonly show a similar pattern of delays and cost overruns.
Do We Improve?
- The execution of construction work has not seen significant improvement over the last 50 years, according to John M. Beck.
- The gross value-added in the United States shows no consistent improvement across different sectors (agriculture, manufacturing, wholesaling/retail, and construction) for the period 1947 to 2000.
R&D Spending
- Research and development (R&D) spending in construction is significantly low, less than 1% annually.
BIM Evolution: Exponential Growth
- BIM has evolved since the 2000s, moving through stages of design coordination, two-track integration, and now towards integrated systems and AI.
- BIM 1.0 characterized by design coordination and clash detection.
- BIM 2.0 marks a step towards integration and full use across multiple sectors (structural, complex façade engineering, site-model synchronization).
- BIM 3.0 and 4.0 move towards lean BIM, automation, and 3D printing.
- BIM 5.0 explores smart city integration and AI enhancements, "connected BIM" and data-driven decision making throughout the project lifecycle.
Research Trends in BIM: Generative Design
- Generative design explores numerous solutions based on given parameters and constraints.
- The process involves creating, evaluating, identifying the best, and evolving the solutions until they meet the required objectives.
- Generative design can improve productivity, enhance collaboration, and create significant buzz.
- Key goals during generative design include adjacency preferences, low distraction workspace, optimal views, and ease of connectivity within the built environment.
Research Trends in BIM: Parametric Design
- Parametric design is a key precursor to generative design when introducing design parameters and constraints.
- The process identifies the variables, their relationships, and develops parametric models to define the building's parameters.
- The current limitations of BIM tools in supporting generative design were also noted.
Research Trends in BIM: Scan-to-BIM
- LiDAR technology measures distances to surfaces based on time-of-flight.
- Point clouds are created to generate BIM models.
- This technology allows for the creation of BIM models for existing structures based on 3D scanning.
- Process involves transforming points clouds into an accurate digital model by detecting walls, creating navigation graphs, subdividing spaces, and modifying walls and rooms.
Research Trends in BIM: Lifecycle Support
- COBie (Construction Operations Building Information Exchange) data format facilitates the collection of information of all assets in a building throughout its lifecycle.
- Data on assets like equipment and their lifecycle characteristics (manufacturing date, installation date, last maintenance, repair history, and next scheduled maintenance) significantly supports asset management.
Research Trends in BIM: Infrastructure Modeling
- BIM can extend to infrastructure modeling, encompassing road, bridge, and utility information.
- A single or network level of representation can optimize infrastructure BIM models.
Research Trends in BIM: Digital Twin
- Digital twins represent a close integration between the virtual and physical worlds.
- Data from the physical world are used to refine the virtual model.
- Real-time operational data, what-if analyses, and predictive maintenance are part of this digital twin approach.
Research Trends in BIM: BIM and Modular Construction
- Modular construction uses BIM to model, plan, manufacture, package, and deliver elements of the structure.
- Using production plans, rooms are tagged using BIM to facilitate delivery.
Research Trends in BIM: Virtual Construction
- Virtual construction uses BIM to simulate the construction process with regards to geometry, time, motions, safety, and other parameters.
Requirements for Successful BIM Implementation
- Successful BIM implementation requires strategic considerations, encompassing people, process, and technology.
- Knowledge and technology accumulation is a crucial factor, achieved through strategic steps during BIM adoption.
BIM Roadmap
- Stages of BIM evolution have been identified, ranging from early coordination and communication BIM to more advanced integration, lean, AI BIM and beyond.
Quotes
- Thomas Watson of IBM believed that a world market exists for perhaps only five computers (1943).
