Progress Update: BIM Workstation at Meixi Lake City Island
1. Revit Modeling Training
Following the implementation plan for the “Meixi Lake Urban Island Project BIM Workstation,” Yang Chao, the resident engineer at the BIM center, initiated Revit training by modeling a single small villa. By September 1st, the project team members had successfully completed both architectural and structural modeling of the villa, gaining proficiency in essential Revit operations.

2. Model Development
The project is divided into four main components: the spiral steel structure, service center, island bridge, and pedestrian bridge. These structures are irregular, featuring numerous inclined columns and beams with varying cross-sections, adding complexity to the modeling process. The diverse angles and component cross-sections, along with scattered design drawings and frequent changes, further increase the challenge. Additionally, integrating the detailed spiral Tekla steel structure model was required, presenting additional difficulties.
The BIM fixed workstation team, leveraging their Revit modeling experience from the training stage, transitioned to project-specific modeling tasks. They completed the Revit model of the service center, which features irregular columns, beams with variable cross-sections, and curved roofs. Since the model will be used for precise measurement and layout, ensuring accurate positioning of every component was critical.
Revit Model of the Service Center
(1) Integration of Spiral Tekla Steel Structure Model
The Tekla model was exported to IFC format and imported into Revit. Due to the large number of components, the resulting Revit model file was very large, requiring significant time and effort to properly locate and integrate the model.

(2) Complete Revit Architectural and Structural Modeling
All buildings in the project, including the service center, island access bridge, and pedestrian bridge, were modeled architecturally and structurally in Revit. These models were then integrated to provide a comprehensive project overview.

(3) Site Layout Modeling
The team also completed a detailed site layout model for the construction area.

3. Proactive Drawing Review During Modeling
On September 13th, a clash detection was conducted using Navisworks on the completed model. The review identified that the pedestal elevation was 20 centimeters higher than the floor level. Additionally, the inclined columns and foundation of the pedestrian overpass conflicted with the service center’s top plate and foundation. Since this section has not yet been constructed, these issues were flagged early.
The BIM workstation promptly reported these findings to the project department, helping prevent project delays and reduce rework costs. The review process is ongoing, with a comprehensive collision report to be submitted. Below are some of the major issues identified:
