In the steel structure design, manufacture and installation process, to "precision control" as the main line, emphasizing the "fine, fine". The supervision engineer should pay attention to the following points:
Measurement and control: in steel structure fabrication and installation process and its measuring instruments, tools must be through the technology supervision department inspection by calibration. At the same time, we must pay attention to accuracy of these instruments is with steel structure production requirements match.
Process control: in the production process of steel structure, the processing method of high accuracy, to predict the process of deformation, take corresponding measures to prevent deformation. Such as welding shrinkage deformation, to eliminate residual release. Small deformation welding, automatic welding method and so on symmetry.
Embedded control: embedded anchor bolts is steel structure installation work projects focused on construction site, must require the construction units in the preparation of special construction scheme, and accurate construction. Under normal circumstances, in front of the construction unit watering Quan, supervision engineers should be on the pre buried bolt for closure of measurement and inspection, in addition to the vertical and horizontal axis measurement outside, but also for check elevation. Before the initial setting Quan has been watered again to recheck, to ensure accurate pre embedded anchor bolts.

(1): anticorrosive coating of steel structure anticorrosion mainly includes atmospheric corrosion and anti corrosion of two kinds of soil. The coating is generally divided into primer, transition layer, middle layer and surface layer four. The supervision engineer in addition to control the thickness of the coating and coating process requirements, the basic performance is to master a variety of coating materials, to effectively control the project in prison. As in the coastal area and long sunshine area, we should pay attention to choose the paint anti ultraviolet and anti salt, acid corrosion.
(2): Fireproof Coatings for steel structure fire higher, its fire resistance and fire resistance rating are closely related, in the same grade of refractory, beam, column and plate fireproof limit of different components in different. But in the construction process is often caused by all components are brush the same thickness of fire protection paint phenomenon. This left vulnerable to security risks, supervision engineer deal with the enough attention, the work should be carefully controlled drawings, on the main structural components limit of fire resistance and fire protection coating thickness were carefully check。
