It seems that tracking and documenting construction progress with a BIM can prove quite valuable when the construction claims begin to roll in. In a 2016 report from Arcadis, the average North American construction claim took over 14 months to resolve with an average value of $21 million so there would seem to be plenty of incentive to invest in a high quality forensic BIM.
The UK has mandated that BIM Level 2 be used by all contractors engaged in government projects. The U.S. does not have a federal mandate, but individual projects are requiring the use of BIM.
Each time the BIM is updated a version can be stored with whatever inspection data was recorded for that update. Photography, 3D laser scans and physical measurements all need to be documented so that they cannot be challenged during the potential court proceeding. Dimensions can be verified, schedule delays documented, defects and omissions noted.
More sophisticated analysis of construction delays can also be run using construction simulation software. Overlays of the laser scans on the BIM can also quickly highlight errors.
The most important value of an accurate BIM is likely in the avoidance of claims. A transparent BIM that is shared with all parties can quickly convince those considering a claim that the likelihood of success will be low.
It is important to include the intended use of BIM in the original contract documents. If limiting claims is not enough justification for maintaining the BIM then having a detailed record for operation and maintenance would seem to close the deal.
