    Application of BIM Strategy for Shenzhen Qianhai Municipal Infrastructure

    Shenzhen, Guangdong, China

Project Summary


Project
In Shenzhen, Guangdong, China the Qianhai Cooperation Zone is undergoing concentrated construction across 14.92 square kilometers of reclaimed land, valued at nearly CNY 390 billion. The development includes more than 180 kilometers of roads and 32 kilometers of rail lines aboveground and belowground, and CNY 68.2 billion in infrastructure. Huadong Engineering Corporation Limited (PowerChina) led BIM implementation and coordination for the 17 designers and two constructors working on multiple, interconnected projects in the region.

Solution
Using Bentley’s BIM solutions Huadong Engineering's daily management and coordination of BIM execution ensured that project participants leveraged the technology to solve the numerous challenges. Overlapping planning, geotechnical, and geographic 3D models of the Qianhai Cooperation Zone created a comprehensive digital model for use in checking construction work against the multi-discipline 3D design models. The 3D reality model of the construction zone also provided a GIS-based view for spatial coordination of projects.

Outcome
BIM implementation provided unified technology standards that enabled disparate engineering teams to work more efficiently. Under the BIM strategy, 3D collaborative design workflows helped finalize the design schemes in 50 fewer days and saved more than CNY 21 million in averted rework. Bentley's BIM technology was utilized throughout the planning, design, geotechnical, and construction stages to deliver a comprehensive city model that will be used for lifecycle management of the municipal infrastructure.

Software
ContextCapture created the reality mesh based on 35,000 photos of an 18-square-kilometer area. Inspection of the worksite through the reality mesh was five times more efficient, allowing 20 site visits per day, saving CNY 5 million. The 3D design models built with AECOsim Building Designer, Power InRoads, Bentley Substation, Bentley Raceway and Cable Management, and other products reduced errors, omissions, collisions, and deficiencies. Navigator streamlined BIM reviews and issue resolution.

Outcome/Facts
  • Huadong Engineering ha utilizzato la piattaforma di management delle costruzioni BIM per gestire l'applicazione, la collaborazione, il trasferimento digitale, lo stato d'avanzamento, la qualità, i costi e la sicurezza.
  • ProjectWise reduced communication time and enhanced cooperation.
  • Il modello 3D completo della Zona di Cooperazione di Qianhai ha riunito modelli informatici di pianificazione, geotecnici, di rilevamento geografico e di mappatura.
  • La simulazione delle sequenze di costruzione all'interno dei sottogruppi di progetto ha ridotto i rischi ed evitato costi aggiuntivi nell'area ad alta densità costruttiva.
Quote:
  • "La piattaforma tecnologica 3D di Bentley ha permesso di risolvere i difficili problemi di pianificazione tecnica e gestionale globale del progetto di costruzione delle infrastrutture di Qianhai. Trattando gli errori, le omissioni, le interferenze e le carenze durante la fase di pianificazione e progettazione e realizzando la simulazione di costruzione in anticipo, abbiamo evitato i rischi di gestione e di controllo e gli sprechi di risorse investite a causa di un progetto imperfetto. Abbiamo realizzato la costruzione di ingegneria digitale, gettando solide basi per la realizzazione di 'Smart Qianhai'".
