during its life cycle Typically it uses three-dimensional, real-time, dynamic building modeling software to increase productivity in building design and construction. The process produces the Building Information Model (also abbreviated BIM), which encompasses building geometry, spatial relationships, geographic information, and the quantities and properties of building components. Utilizing BIM has the potential to save project time and cost and increase overall productivity of construction and delivery of building projects with less rework, design, and construction errors.

The advantages of BIM over the traditional design and construction process are significant (source: Construction Delivery Systems, Lorence H. Slutzky, 2008):

BIM single data entry into one model avoids the opportunity for inconsistency and error of repeated input of identical data in multiple media. Data once entered or altered is available in the single current model available to all.
BIM design efficiency reduces the cost of design and preparing contract documents.
BIM base information is uniform and shared with all participants.
BIM three dimensionality and software identify physical conflicts between elements reducing significant construction delay, and extraordinary additional expense. Where modifications are suggested, the impact of the proposed changes are immediately apparent, subject to evaluation and reconsideration.
BIM three dimensionality assists in sequencing and constructability reviews.
Confidence in shop drawing and fabrication accuracy is improved by BIM because the model can provide construction details and fabrication information. More materials can be fabricated more economically off site under optimal conditions due to the confidence in the accuracy of the fabrication.
BIM can link information to quantify materials, size and area estimates, productivity, material costs and related cost information.
Overall, the BIM digital model becomes a rehearsal of construction and can help identify conflicts and their resolution before actual construction dollars are spent.
