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.
  • 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.
  • 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.
  • 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.
  • 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.
  • BIM can extend to infrastructure modeling, encompassing road, bridge, and utility information.
  • A single or network level of representation can optimize infrastructure BIM models.
  • 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.
  • 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.
  • 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).
