ERECTING PREPARATION 1) TRANSPORATION 2) ARRANGEMENT OF ELEMENTS ON SITE 3) PRE-ERECTION (AMPLIFICATION) 4) STRENGTHENING ELEMENTS 5) SELECTION OF ERECTING DIRECTION 3. ERECTING PREPARATION 1) TRANSPORATION OF STRUCTURE ELEMENTS FACTORY REMOVING (Bốc xếp) CONSTRUCTION SITE MOVING (vận chuyển) LOWERING (Hạ - TO INTENDED PLACE) OF STRUCTURE ELEMENTS 3. ERECTING PREPARATION 1) TRANSPORATION OF STRUCTURE ELEMENTS PRINCIPLES (6): 1. Strenth of element must obtain that for moving. For concrete one, strength must having at least 70% of R28. 2. Element situation during moving should be similar to that at working condition (just to avoid stresses occurred different as disigned) WORKING SITUATION OF ELEMENTS 3. ERECTING PREPARATION 1) TRANSPORATION OF STRUCTURE ELEMENTS PRINCIPLES (6): 3. Bending elements must be chocked by using wooden pieces following designed positions (hook position) 3. ERECTING PREPARATION 1) TRANSPORATION OF STRUCTURE ELEMENTS PRINCIPLES (6): 4. When members laid on each other, supported (chocked) points should be on a vertical direction 3. ERECTING PREPARATION 1) TRANSPORATION OF STRUCTURE ELEMENTS PRINCIPLES (6): 5. When a long member is laid on 2 rail carriages, it should be supported on 2 different points, so the carriages can be rotated during transportation. Support point – rotation point 3. ERECTING PREPARATION 1) TRANSPORATION OF STRUCTURE ELEMENTS PRINCIPLES (6): 6. Length of structure member should be fit on truck, so it could be passed at corner of streets or roads. 3.

ERECTING PREPARATION 1) TRANSPORATION OF STRUCTURE ELEMENTS MEMBERS ARRIVED CONSTRUCTION SITE 3. ERECTING PREPARATION 2) ARRANGEMENT OF ELEMENTS ON SITE PRINCIPLES (2): 1) Member should laid in working radius of crane 3. ERECTING PREPARATION 2) ARRANGEMENT OF ELEMENTS ON SITE PRINCIPLES (2): 3. ERECTING PREPARATION 2) ARRANGEMENT OF ELEMENTS ON SITE PRINCIPLES (2): 2. Places of laid members should follow the location of crane, in which the crane can pick up them as much as possible. Heavy member is laid near the crane. Lightweight member is laid far from crane. 3. ERECTING PREPARATION 3) PRE-ERECTION (AMPLIFICATION) ROOF STRUCTURE (SPACE FRAME WITH SPHERE NODES)
