Recently, the CSCEC-built Lenovo project in the Houhai area in Nanshan District of Shenzhen was completed.

With a total construction area of about 300,000 square meters, the project consists of a 204-meter-high and a 140-meter-high office buildings. Based on the construction and design requirements, the two buildings "turn around" at a 90-degree angle on shelter floors, expanding people's vision of the Shenzhen Bay to the biggest extent.

With BIM technology applied in the whole construction process, three-dimensional visualization models are adopted to select steel structure plans, to simulate installation, and to optimize steel structure nodes so as to assemble in advance and rectify deviation.

In order to provide unique three-dimensional green space, the team adheres to the concept of green construction, carbon peaking and carbon neutrality, and energy saving in the construction. For example, when the equipment in the machine room is performing prefabrication and installation, the team adopts BIM models to dismantle members so as to reasonably increase tube sections and the arrangement of supporting structures. In addition, the factory machines materials according to one-to-one drawings and directs the installation on the construction site through simulating visualization installation and light-weight models on mobile devices, which are safe and environmentally protective.

The construction team builds sponge facilities including rainwater gardens, water-permeable pavement, green building surfaces, blue roofs, rainwater recycling pools, and rainwater reservoirs, designs a rainwater recycling area of 6,190 square meters, and set an environmentally protective system of recycling and reusing water resources. All these will improve the city's ecosystem function and reduce the occurrence of floods.
