Instruction: Read the following case study and answer the question that follow.

Chengdu, China Chengdu is the capital of China$$s Sichuan province. It is undergoing a CNY$1\mathrm{.}38$bn road reconstruction project in the Shanbanquio area of the city, involving $4\mathrm{.}3$km of roads, as well as bridges, tunnels, an underground pedestrian passageway, pipeline and auxiliary works. The main road needed to accommodate cars travelling at $60$km per hour $$ auxiliary roads would support

speeds of $40$km per hour. The project team faced several design challenges. There were space constraints between the elevated and lower portions of the roadway and the connectors. The designs had to ensure smooth traffic flow on the connectors and slower lanes that connect to commercial businesses along both

sides of the roadway. The project team then had to consider how it would design a safe pedestrian passage system along the green space and parks next to high traffic areas. The company leading the project, Chengdu Urban Construction Investment Management Group, required a high level of coordination at the design stage to avoid mistakes, omissions, and collisions. The team used Bentley open modelling and simulation applications to create digital twins of all

project assets. This was used to model bridge structures and develop a strategy to minimize the impact on local traffic. ProjectWise was chosen to store the road network information required for traffic simulation. This helped the team to increase internal work efficiency by $20\%,$ detect and resolve $16$ collision points, and reduce construction drawing time by $120$ hours. Using LumenRT for

visualization shortened the approval process by $15\%.$Intelligent transportation and the digital model are the foundation of a digital city. Digital twins

provide a lightweight model, which expands the use of BIM applications beyond the project to the delivery of digital assets. Digital twins can be directly applied to the owner$$s planning, construction, demolition, and other management,$$ said Yanxiang Wang, BIM engineer, Chengdu Urban Construction Investment Management Group.

$1\mathrm{.}1$ Project success can be declared by completing a project within scope and cost, on time and of high quality and exceeding the customer expectation. Imagine that you are the project manager of the case study project. You are required to critically discuss the project lifecycle plan for your project. In your discussion clearly show how each stage of the project lifecycle resonates with your project.
