CityLink SongShan BOT Project
Hong Kong recently began updating and maintaining an electronic database of its historical buildings. Pilot projects were initiated to
leverage point-cloud technology. But before creating a 3D model, Sigma Mascot needed to consider how to scan the especially fragile
buildings. The solution for this HKD 300,000 project was to capture the point-cloud data and then import it into Bentley Pointools.
By deploying 3D scanning in conjunction with Bentley Pointools, Sigma Mascot no longer required a crew to do the survey on site. In
addition, the highly efficient equipment reduced operational costs by providing an accurate 3D model with a less than 3-millimeter error rate
on the data acquired. MicroStation then was used to rebuild the 3D model and save the files in DGN, 3D PDF, and video formats for inclusion
in the database.
The goal of this USD 130 million project was to renovate the SongShan railway station and a 21-floor multifunctional building for the
Taiwan Railway Administration. Comprised of offices, retail establishments, and a hotel with total gross area of 115,779 square meters, the
complex currently averages about 30,000 visitors a day. Once transformed into a mass rapid transit station, the number of passengers is
projected to double.
Using AECOsim Building Designer, Bentley Navigator, OpenPlant, and Bentley Raceway and Cable Management, the Ruentex Group created
multistage, data-rich BIM models for monthly design review and clash detection, prioritization of construction sequences and constructability
reviews, and 3D auditing against physical models. The BIM approach was expected to decrease project delivery time by 15 percent.
