the mechanical and electrical engineering project cost a comprehensive control implementation progress Second, the mechanical and electrical engineering project cost. A comprehensive control implementation progress Mechanical and electrical engineering project cost a comprehensive control progress, not only have the effect of cost control, progress control, and can reflect the management level of the contractors and the ability to cope with risks. Mechanical and electrical engineering project cost. A comprehensive control progress, not only have the effect of cost control, progress control, and can reflect the management level of the contractors and the ability to cope with risks. 1. Mechanical and electrical engineering project system is established 1. Mechanical and electrical engineering project system is established Mechanical and electrical engineering with industrial equipment, pipelines, electrical equipment, automation instrument, corrosion resistance, heat insulation, industrial furnace lining equipment installation; Building mechanical and electrical engineering has a building water supply and drainage, ventilation, air conditioning, building electrical, intelligent building, elevator installation, etc. And each subdivisional work in measuring unreeling, infrastructure installation, equipment installation, cable laying, wire connection, equipment debugging, commissioning and other processes, forming a relatively large and complex system. In order to better implement comprehensive cost and schedule control, from process to the project reasonable classification, and coding, form a system of the project. Mechanical and electrical engineering with industrial equipment, pipelines, electrical equipment, automation instrument, corrosion to hold, heat insulation, industrial furnace lining equipment installation; Building mechanical and electrical engineering has a building water supply and drainage, ventilation, air conditioning, building electrical, intel
