This project represents the first phase of the Shenyang Vanke Zitai development, undertaken by Shenyang Vanke Zitai Land Co., Ltd. The site is located in Huanggu District, Shenyang City, bordered by Baihua Mountain Road to the north, Furong Mountain Road to the south, Huanghe Street to the west, and Mudanjiang Street to the east.
The development includes six multi-story commercial buildings, ten 23-story residential towers, four 22-story residential towers, one 21-story residential tower (with one floor partially allocated for commercial use below), and an underground parking facility serving the entire site.
The original BIM team was involved in four sub-projects within this development: a single-story basement (DX1), commercial buildings (S-3, S-6), a high-rise residential building (Building 5), and a sales office (S-1, S-2).
BIM technology was applied at varying levels of depth and scope across these four components.

Key Applications of BIM Technology in the Project
1. 3D Virtual Modeling & Collision Detection
Starting from 2D construction drawings, detailed 3D BIM models were created by discipline, simulating spatial occupancy and accurately reflecting design intent. The model detail level ranges between LOD300 and LOD400. Once individual discipline models were completed, they were integrated into a comprehensive design model through linking and imported into Navisworks software for automated clash detection.
This process efficiently identifies conflicts among architectural, structural, and MEP (mechanical, electrical, plumbing) components. The clash detection report captures all points of conflict within the integrated model, compensating for manual inspection limitations and facilitating 3D coordination. The report’s coordinates also guide subsequent pipeline layout optimizations.

2. Pipeline Coordination & Net Height Analysis
Using the collision detection report as a reference, conflicts were analyzed and resolved with project net height requirements serving as the minimum control standard. The integrated model was used to rationally arrange mechanical and electrical pipelines, eliminate clashes, and minimize rework during construction.
The adjustments not only resolve identified conflicts but also ensure adequate space for installation and maintenance of pipelines, supports, and hangers. The optimized model meets net height requirements effectively.

3. 3D Collaborative Platform & Project Management
A lightweight BIM collaboration platform was implemented to share models with the client via the Internet. This allows the client to view the model online without installing Revit software, monitor project progress in real time, and explore the virtual project environment to experience the final construction effects.

Feedback from Homeowners
1. More Scientific Guidance for Construction
By optimizing the MEP pipeline layout, the project has effectively reduced the need for dismantling and rework, providing strong technical support for smooth project execution.
The benefits of pipeline optimization are especially apparent in the basement, where pipelines are dense and intersections prone to severe clashes. Due to small column spacing (average 5.4 m) and low floor height (3.0 m net height under the slab), corridor spaces connecting residential buildings are narrow, leaving limited room for pipe installation.
Leveraging BIM’s 3D visualization capabilities, collision points were easily detected, significantly reducing demolition and modification during construction. The virtual modeling also enabled preemptive pipeline arrangement to meet net height requirements, ensuring comfortable space usage and providing scientific guidance to the construction team.

2. Enhanced Design Quality & High Customer Satisfaction
BIM proofreading uncovered multiple conflicts among building plans, elevations, installation components, and structural elements—such as clashes between staircase beams and windows or beams and doors. Feedback was promptly provided to designers to optimize drawings, reducing unnecessary waste.
Furthermore, BIM visualization verified the design’s visual impact. For example, the model revealed internal beams visible from outside windows in parts of the sales office, which, while not a collision, affected building aesthetics—an insight difficult to achieve with traditional 2D design.
By identifying blind spots in conventional 2D design through BIM, the team ensured continuous improvement in design quality and customer satisfaction.

During the BIM modeling of the show house, the original designer also found clashes between electrical endpoints and between electrical endpoints and furniture. Feedback led to adjustments in planning and elevations, avoiding costly demolition and renovations, while ensuring interior usability and customer satisfaction.
Our Takeaways
The implementation of BIM technology in this project added significant value during the design phase. BIM provided strong technical support for smooth project execution, a benefit recognized and appreciated by the client.
In today’s competitive construction market, BIM-assisted refined design is an emerging trend. Original Architecture International Design Consultant remains committed to exploring various BIM applications to help clients deliver high-quality, iconic projects.
