The document discusses Virtual Design and Construction (VDC) as a method for simulating the architecture and assembly of building projects, aiming to reduce risks, improve efficiency, and control costs. It outlines the advantages of using VDC such as enhanced project planning, clash resolution, and accurate quantity take-offs, along with case studies demonstrating its effectiveness. The adoption of VDC and Building Information Modeling (BIM) is highlighted across various sectors, emphasizing a shift towards more transparent and efficient processes in construction.
