Heilongjiang Construction Kechuang Investment Group provides infrastructure and municipal utilities construction among its many services. Targeting long-term productivity, profitability, and sustainability, they charged their subsidiary, Heilongjiang Construction, Science and Technology Innovation (HCSTI), to construct the Construction Industry Modernization Demonstration Park in the Xinli area of South Harbin, China.
Covering 1.26 million square meters, the main purpose of the 3.6 billion CNY park is to help the group refine its project delivery and manufacturing processes for the inclusion of prefabricated components in infrastructure projects. It is hoped the park with contribute to a broader objective to adopt greener and more environmentally friendly construction methods in Heilongjiang province and help the group position itself as a key supplier, integrator, and service provider. The facilities at the park will be used to manufacture prefabricated components including building steel structures, road and bridge steel structures, special concrete and curtain walls, and process technology systems. HCSTI is responsible for coordinating and implementing the planning and design of the park and, once built, managing production, operations and maintenance.
The team at HCSTI is going digital with Bentley software, and is using Bentley’s open modeling and simulation applications to design and construct each of the buildings and related infrastructure within the demonstration park. They will refine and test industrialized processes as they execute their own project, building all structures with prefabricated components also designed with Bentley applications. Industrializing construction requires rethinking and redesigning processes, and innovators must be open to new material choices and fabrication and installation methodologies. The sheer quantity and variability of workflows, overreliance on bespoke on-site methodologies, scattered workplaces, and short project cycles all contribute to undermine construction productivity and prevent the advances enjoyed in other industrial sectors.
HCSTI faced many challenges in the early stages of the project, including a very tight schedule, many collaborating stakeholders, and the need to bring manufacturing rigor to design and construction documentation. Further, they needed to integrate design, production scheduling, production, transportation and other processes, to avoid low production and inefficient use of resources.
In planning the layout of the park, HCSTI challenged the site design team to create a road system that maximizes efficiency and optimizes locations for handling and construction of the prefabricated components. ContextCapture was used to create a reality 3D model of the project area. OpenRoads ConceptStation leveraged this context to generate layouts for roads and ancillary facilities, including holding areas for materials and constructed components. Navigator then helped the team detect and resolve clashes, after considering size and weight of the manufactured components to determine the best route from production to storage. When compared to traditional planning methods HCSTI’s use of Navigator in site layout optimization resulted in a 50% increase in vehicle accessibility and utilization.
During design and engineering, the multidiscipline design team used ProjectWise to manage its work and provide a secure, reliable, and unified working environment, increasing productivity by 50%. A primary goal of the project was to integrate design and construction and ensure that all design changes could be delivered to design, scheduling, and production stakeholders at the same time.
A library of components was built using OpenBuilding Designer for doors, windows, and other prefabricated components, which were then used to design the buildings and to plan manufacturing and construction. The rigor in the design of the components enabled the team to conduct detailed analysis and refine and improve their designs.
STAAD was used to design and check temporary structures at the construction site and to analyze BIM models to Chinese standards, increasing the efficiency of design and design checks. ProStructures was used to model the steel structures of the production workshops, as well as to optimize the design of prefabricated components. The information from the prefabricated components is being directly used by the CNC machining equipment, ensuring that data can move from design to the machines in assembly lines, making the whole production process extremely intelligent and effectively controlling production costs. MicroStation is being used to templatize and optimize line layout and assembly scheme for prefabricated components, significantly reducing the time to plan production for new components.
“Bentley’s solutions are highly effective when applied to the whole lifecycle of the Heilongjiang Construction Industry Modernization Demonstration Park project,” said Xuyuan Liang, general manager assistant of Heilongjiang Construction Kechuang Investment Group. “No matter which party – the builders, the designers, or the constructors – and no matter which phase – the design, construction, production, and management – we are in, we have realized the superiority of the digital twin model in the treatment of project delivery and asset management. Moreover, the innovative working and production management methods have saved us a lot of manpower and raw materials and helped improve the turnover efficiency of machines and templates.”
