Building information monitoring is an essential procedure in construction works that have to be done by building surveyors. With the help latest techniques of laser scanning and point cloud to BIM, surveyors interpreting construction plans and marking the location of proposed new structures such as roads or buildings in very appropriate order quantities.
Scan to BIM is used for the BIM modeling for scanning the building structure via high-quality scanners, LiDAR, and drone with the advanced designing and modeling tool like Revit and give insights into rich 3D model. For the AEC firms, Scan to BIM support for the refurbishment, support structures, temporary construction.
The accuracy of BIM Quantity Take-Off and consequently material procurement!!
While underestimation of the cost leads to loss of money, the overestimation may result in failure at the bidding phase.
Even though the direct victim of this issue in traditionally fixed price contracts is a contractor, the impact of poor estimation will be seen in the entire project.The typical pain areas for BoQ’s industry-wide are:As quantity take-off from 2D drafting is not connected to the resulting BOQ dynamically, the surveying team has to take many days in order to visualize the construction of 2D drafting.Even though BOQ industry needs the cost and resource loaded schedule.
But a third structure should be mapped to these two for cost controlling and cost capture.ESTIMATING PROCESSA baseline of the cost required at the various stages of project development is called cost estimation.
Unit cost method is based on a simple arithmetical principle and is very accurate in estimating.
BIM represents a single and accurate design model instead of providing several drawings.
