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.
