Abstract：Beijing Jingcheng Mansion is a high building with 50 storeys on the ground and 4 storeys under ground. The building was designed by Japan and constructed by Beijing Machinery Construction Company. Four million RMB yuans were saved compared to the initial project，as some peculiar construction measures were adopted，such as three-layer bolts，inner-external slopes，excavators working in channels. The successful experience was learnt from this engineering on supporting slope piles，bolting and earthwork construction.
