Abstract：
Wangjing SOHO-T3 building adopts irregular arched shape, whose planes and facades are composed of curves, producing great difficulties for measurement control and positioning of structural slab edge curve. Experiences of similar projects are referred and total station is used to simulate line drawing, successfully solving the contradiction between measurement speed and accuracy; the design of cantilever eaves board is changed through negotiation with the design unit, to guarantee convenient construction and construction quality. Verification result indicates that the error is within 20 mm, satisfying the requirements for control of slab edge line.
