Due to the experience gained from building the first heat supply hub, both Chen Xin and Cao Daren improved the construction process when building the second hub, making its construction smoother.
For instance, when constructing the first heat supply hub, Chen Xin and his team excavated the snow, laid the foundation underground, and then started assembling the hub. However, they didn't do the same for the second hub.
They adopted a method where they excavated while assembling the heat supply hub simultaneously. Once the pit was dug out, the equipment was assembled and only needed to be fixed onto the foundation.
This construction method undoubtedly saved a lot of time. Although the installation period for a heat supply hub isn't very long, saving some time is always beneficial.
While the workers were engrossed in the construction, Wang Hai led his squad to spread out for security, while Chen Xin and Cao Daren discussed the next construction steps.
