1. Rules of planning 1.1 The documents and the acceptance regulations instructions for the quality of building work, which are issued by nation, industry or local government, involved in the construction of civil work are as follows： [Regulations of engineering measurement] (GB50026-93) [Instructions of construction measurement in building work] (DBJ01-21-95) [Instructions of deformation measurement in engineering] (JGJ/T8-97) [The acceptance regulations for the quality of construction of steel structure] (GB50205-2001) [The acceptance regulations for the quality of construction of concrete work] (GB50204-2002) 1.2 The initial data of level and altitude are based on the points of SWC22 and SWC24 supplied by the owner, i.e. Riyadh Cement Company. The relation converted between the coordinate system of construction and that of measurement is as follows: X=（N-N0）cosθ+（E-E0）sinθ+X0 Y=（E-E0）cosθ-（N-N0）sinθ+Y0 N=（X-X0）cosθ-（Y-Y0）sinθ+N0 E=（Y-Y0）cosθ+（X-X0）sinθ+E0 X0=-100.000, Y0=100.000 N0=2687000, E0=632800 θ=29.813。 The initial data of level and altitude are as follows SWC24：N =2687262.704m E =632412.184m H=847.540m (X =-64.8750m Y =-367.0984m) SWC22: X =2687186.364m Y =632804.400m H=841.689m (A =63.8868m B =11.1629m) 1.3 The draws of construction are based on the general layout that is designed by the Sinoma .Ltd 2.
