BIM models developed with point cloud modeling, can minimize budget overruns

Budget overruns used to be very prominent or obvious in renovation and refurbishment projects, wherein gathering project information was not that easy.  Before the existence and inception of Scan to BIM services, design and construction professionals had to work round the clock, for the successful extraction of information from the existing building. AEC professionals such as architects and engineers had to make many visits to the renovation site even for small doubts. Before the application of scan to BIM, AEC professionals had to perform a manual survey of the property for measuring its correct dimensions for developing drawings.  But the effectiveness of these drawings always used to be doubted by architects and engineers as manual survey was prone to human errors.

Renovation projects used to involve a lot of complications, which ultimately resulted into budget overruns. Due to high complications rework was obvious and budget overruns are the consequences of that.

But budget overruns of renovation projects have drastically decreased, after the implementation of scan to BIM process, wherein error-free building data is collected through laser scanning techniques. Error free building data is highly important for the successful execution of these projects, as implementation of right information during renovation can reduce rework.  Laser scanning technology is used by many industries for increasing their productivity and AEC industry has also implemented it for the same. Laser scanning saves a lot of time as it provides architects and engineers with correct building geometry which can be used by BIM modelers during BIM modeling services.

Laser scanners can scan each and every part of the building in details and can extract accurate existing conditions of the building in question. Laser beams directed from laser scanners reach deep inside the structure and capture tremendously factual information that is necessary for project execution. Building information is incorporated in point clouds which are brought by laser beams when they come back after examining the building. For a thorough examination of the building, scans are captured for different parts from different angles. Scans captured for different sides and from different angles are clubbed together by the survey team for the ultimate purpose of acquiring comprehensive information. This data is now delivered to an eminent service providing company which creates immensely informative and powerful BIM models from it.

By executing point cloud modeling, Revit users can develop informative BIM models for architecture, structure and MEP, which can assist AEC professionals when they carry out renovation on the proposed location. As accurate information about design, construction and operations can be obtained from these models, they can help in minimizing budget overruns.
