Shenzhen Construction Engineering recently held a Quality Month observation event at Shangsha Station on Metro Line 7. According to the Municipal Housing and Urban Rural Development Bureau, BIM technology has been applied in the construction of Line 7, significantly enhancing construction efficiency. Currently, track laying is still in progress and is expected to be completed by the end of this year, with trial operations planned for the end of 2016.
Metro Line 7 begins at Lishui Road in Nanshan District and terminates at Tianbei Tai’an Station in Luohu. It connects several key areas, including Xili, Longzhu, Chegongmiao, Futian South, Huaqiangbei, Sungang, Tianbei, and Buxin, covering a total length of 30.173 kilometers. The line is part of the third phase of Shenzhen Metro’s major projects, featuring a fully underground route with 28 stations and 27 sections. The project also includes the construction of the Shenyun Vehicle Depot and Antoshan Parking Lot.
To enhance project quality and safety while shortening the construction timeline, BIM technology is being utilized to guide the construction of Metro Line 7. For example, at Shangsha Station, BIM transforms two-dimensional plans from multiple disciplines and intersections into three-dimensional visual models. This allows early detection of design issues, optimization and refinement of the design, and a reduction in errors and clashes.
“The preliminary use of BIM technology during the post-construction phase of Shangsha Station has already identified and resolved over 400 design errors and omissions ahead of time. Additionally, converting two-dimensional drawings into three-dimensional visual models, along with creating various professional renderings and walkthrough animations, provides on-site visualizations that help frontline construction workers better understand pipeline installation,” explained a representative from the Municipal Housing and Urban Rural Development Bureau.
Currently, track laying on Metro Line 7 is underway, with full track connectivity expected by the end of this year and trial operations scheduled for next year.
