When Building Information Modeling is used to its greatest potential, it can optimize the entire process of building, from early preliminary design through to construction and operations.
The MacLeamy curve shown was developed by Patrick MacLeamy, chairman of HOK (global architectural design and services firm), to represent the advantages of replacing a traditional drafting-centric workflow with a BIM workflow.
The investment during the detailed design phase in the BIM workflow allows for a greater ability to impact cost and performance, which results in a reduction of overall costs. By focusing efforts earlier on in the design phase, the BIM workflow can save a lot of time, effort and resources later on.
Benefits of working with BIM include the following:
Simplified Clash Detection
The project team can find discrepancies between various disciplines earlier in the project and avoid reworking later on when costs and time needed increase. For example, if a structural beam conflicts with a mechanical duct, it could be noticed within the BIM model and resolved prior to construction.
Increase in Productivity
Better collaboration, reduced errors, and fewer requests for information and
confusion on the construction site are a few of the ways BIM brings about more productive workflows. The dynamic features of BIM software allow for faster design changes and embedded data in the model shared with the entire project team saves communication time.
Time and Cost Savings
Along with increased productivity, comes savings in labor and material costs on a project, from the design phase through to construction. Because design and construction are dynamically linked in the BIM workflow, time needed to execute design changes, and produce construction documentation is reduced significantly.
Higher Returns on Investment (ROI)
According to the McGraw-Hill Construction report, over 80% of expert BIM users report positive returns. After initial investment and BIM workflow integration, most project teams notice reduced design change costs, less time needed to manage requests for information during construction and ultimately an optimized profit-earning potential.
Gain Competitive Advantage
BIM is becoming more commonly requested by clients, owners and governmental agencies. Therefore, to be able to offer superior services to your clients, you have to maintain a competitive edge. Your clients will be happy to hear how they too can save time and money by working with you.
Detailed data about every aspect of the building is factored into the BIM model. Therefore, it is a true digital representation of the building, which can be provided to the building owner for easier long term operation, maintenance and repairs.
