PRE-CONSTRUCTION
Building Information Modeling (BIM)
BIM improves the ability of design and construction teams to structure and exchange information through shared, computer-based models of a building project. Benefits include better design coordination, reduced costs and improved communications throughout the design and construction process.
By involving all key team members in creating an accurate digital model of the building, many of the risks and uncertainties common in the construction process are greatly reduced. A building's operational life performance can be optimized before it is even built.

BIM is as much a process of generating, sharing and managing project information throughout the lifecycle of the asset as it is the digital model itself.
Benefits of BIM to a project include:
- Accuracy of design, cost estimating, work scheduling, fabrication and construction
- Improved overall project quality
- Improved coordination of design and deliverables between disciplines
- Enhanced project understanding through visualization
- Improved design management and control
- Enhanced understanding of design changes and implications through parametric modeling
- Ability to perform cost analysis as the design develops
- Ability to understand cost impacts of design changes
- Improved accuracy of cost estimates
- Reduction of construction risks through identification of constructability issues early in the design process
- Ability to model impact of design changes on schedule and program
- Ability to integrate contractor/subcontractor design input directly into the model
- Reduced number of change orders during construction
- Reduced number of requests for information
- Ability to perform procurement from the model
- Ability to update the model with real-time information based on actual performance through the life of the building
The combined financial impact of all these benefits can produce significant savings.
