QP 6 Qualification and Categories 3.1 TYPES OF STRUCTURES: Complex structures encompass a wide range of structural types and
14、 configura-tions. Although the required evaluation functions are similar for all complex structures, the specific skills (e.g., rigging or pollution controls) are sometimes quite different for painting a bridge and painting a process facility.This procedure does not differentiate between contrac-tor
15、s engaged in work in different industries and on different structures. Owners will often select contractors with the specific skills and experience required for the particular job at hand. Some industrial subcategories with which specific skills are often associated are listed below:SSPC-QP 6July 1,
