Key Insights

• 👯 BIM is a process that integrates people, technology, and processes to create 3D models that facilitate improved cost outcomes, collaboration, and design optimization.
• 👻 BIM allows for faster data extraction, reducing the time spent on counting and measuring quantities manually.
• 🖐️ Quantity surveyors play a crucial role in validating and verifying the accuracy of BIM models, as well as providing cost planning and value engineering expertise.
• ❓ Implementing BIM requires effective communication and collaboration between quantity surveyors, architects, and engineers to address modeling challenges and ensure accurate quantities.

Questions & Answers

Q: What is BIM and how does it differ from traditional drafting?

BIM is object-based data modeling that allows designers to create models using a library of objects, which contain properties and interrelationship information. It differs from traditional drafting as it provides a more detailed and interconnected view of the building components.

Q: How does BIM benefit quantity surveyors and estimators?

BIM improves cost outcomes by enabling faster data extraction, allowing quantity surveyors to provide better advice and feedback to the design team. It also facilitates collaboration and the ability to optimize designs through virtual testing before construction begins.

Q: How does BIM contribute to the government mandate for BIM adoption?

BIM adoption is mandated by governments to improve efficiency and cost savings in the construction industry. BIM allows quantity surveyors to actively collaborate with architects and engineers, contributing to the development of the design and providing valuable cost planning expertise.

Q: What are the challenges in implementing BIM for quantity surveyors?

Challenges in implementing BIM include dealing with poor and lazy modeling practices by architects and engineers, as well as the need for validation and manual measuring of non-modeled items. It is important for quantity surveyors to communicate with designers and provide feedback to ensure accurate and reliable models.

Summary & Key Takeaways

• BIM is a powerful agent for change in the construction industry, allowing for the integration of CAD and BIM data into estimating and scheduling workbooks.

• The key aspects of BIM include the universal application of 2D and 3D, live linking of quantities to workbooks, and the ability to showcase changes in drawings and update quantities.

• BIM allows for better cost outcomes, faster data extraction, and improved collaboration between architects, engineers, and estimators.
