Though laser scanning in Vietnam was not popular until recently, more clients have realized the advantages of such technology for optimizing processes. For instance, 3D laser technology was used to install railings that bend with curved staircases on a four-story villa project. Traditional measuring methods would have been more expensive and less accurate. Though the initial cost of this technology is higher, it increases precision, reduces construction costs, and lowers risks. The success of this 3D laser application has helped an interior design company in Vietnam appreciate the value of technology, which has improved the quality of its products and attracted new customers.
