In designing facilities for healthcare, we have developed and refined our use of BIM technology for the collaborative design of buildings and infrastructure elements. For each project we enter all user and technical requirement specifications into a database connected to the various CAD tools for design, clash detection and quality control. These are combined into a single 3D computer model and shared among stakeholders, including architects and engineering design team, building contractors, the healthcare provider, and medical staff.
As design and construction plans progress, BIM enables clashes to be detected and fixed before they become problems on the construction site, allowing the team to analyse alternatives, identify issues and solve problems before they occur in real life. This minimizes construction re-work, greatly reducing risk and saving time and money.
During construction BIM allows the contractor to fine-tune construction scheduling, generate material lists and quantities, to establish material delivery schedules and logistics, and to respond more quickly to design changes or site problems.
