3.Materials checking: 1)Check the material list according to the Construction Detail, and then check objects according to the list, to avoid affecting installation schedule because of lacking components. 2)Check materials, the damaged or deformed should be rectified and repaired, and clashing painting parts should be made up. 3)Check qualified material quality certifications, English and Chinese signs, inspection reports and re-inspection reports. 4.Preparation of construction 1)Construction site should be flat and roads, water, electricity, storages and communications should be clear on the scene. 2)The construction site should have: office, rest, life, production, storage and other temporary housing. 5.the test of foundation buried bolts Use the theodolite and steel ruler to fix the base point, on which vertical and horizontal axis should be drawed. Then check anchor bolts according to the axis, and allowable deviation of the anchor bolts should be within 2MM. 2)Use the level instrument to take level of anchor bolts, allowable height/level deviation of the anchor bolts should be within 5MM. 3)The axis, height/level, deviation of the anchor bolts should be reported when they exceed the allowable norms. The responsible party should rectify the deviation according to the program performed by building and supervising teams.
V.Installation of steel columns:
1.Preparation: 1)Check up components and drilled holes of steel columns correctly. 2)Use theodolites to adjust level of the anchor bolts to ±0.00 3)Use forklift to transport steel columns to position for the convenient purpose of lifting by crane. 4)Draw axises around the column or position paralleled to the axis. 5)Roll iron sheet into a cylinder and set into the anchor bolt to prevent damage screws when steel column falling down. 2.Hoisting: 1)Hoisting should be started from axis between steel columns. 2)Because of vertical hoisting installation, colligation point of column should be at the position of 2/3 of total length. 3)A hemp rope should be tied to the bottom side to prevent the column over-swing in the process of lifting. 4)When steel lifted off at about 200mm above the ground, rigging and crane should be checked and confirmed safety, then the hoisting can be continued. 5)When steel column is lifted at 20-50mm above the anchor bolts, two feet catch the steel column to make the hole on the base anchor collimate the bolt rod while constructing the crane to lift down slowly and adjust the position continually to make the axis on steel column in accordance with the axis on the base. When both axies are fit, install inner plate to tighten the anchor bolt. 6)Remove hook after strengthening the steel column temporarily by using cable wind rope. 7)Hoist second column followed the above methods, removing hook after installing supports and tie bar between columns. 8)Hoist other columns one by one in the same way, meanwhile, installing the supports between columns and tie bars, then two purlines can be installed on the gable as supports. 3.Calibrating columns 1)At the time of hoisting the second column, placing two theodolites separately to both axises of the first installed steel column to examine the verticality of the steel column (allowable deviation of verticality of the steel column is within 5mm). Adjust nuts to make the verticality of the steel column to the required standard when the deviation exceeds. 2)Calibrate other columns in the same way. 3)Retest the steel column after installation of the supports and tie bars, and adjust the steel column to meet the requirement.

VI.Installation of steel beam
1.Preparation: 1)Check whether components and bolt hole of the beam are consistent with the construction details. 2)Assemble steel: because the steel beam is composed of three parts in this project, the three parts must be assembled before hoisting. The specific method is: first, to adjust the theodolite to a level, and then assemble the parts into one beam by using the forklift according to the construction details, finally fix it by using high strength hexagonal bolts (see detail construction methods of high strength hexagonal bolts below). 2.Installation of high strength hexagonal bolts: 1)pre-installed A.Examine the box: the things in this box should include a pair of high strength hexagonal bolts (including a bolt, a nut, two gaskets), Certificate of Conformity and Product Quality Certification. B.Calculate the final fastening value of the high strength hexagonal bolts according to the torque coefficient of the Product Quality Certification. C.Check up the rubbing surface to make sure it's dry, dustless and non-polluting; otherwise they should be dried. Make the surface flat and smooth. 2)installation A.first, paunch temporary bolts and nails into column (the nails should not be more than 30% of the temporary bolts, and the total number of nails and temporary blots should not be more than 2 and less than 1/3 of all the holes.), and than fix the left holes with high strength hexagonal bolts and tighten them with wrench. B.high strength hexagonal bolts should be in the same direction on the nod, convex side of the nut contacts with chamfer of the gasket, which should head towards the bolt head. C.first and final tightening of high strength hexagonal bolt: the order should be started from the center of the nod to the two ends. Have a mark for each tightening and fixing a high strength hexagonal bolt and screw the end of the beginning of the screw. And each must be fixed completely.
