The fire protection power distribution system adopts a dual redundant design, and the cable usage far exceeds actual demand.
The fire protection power distribution system is critical infrastructure that ensures building fire protection equipment continues to operate under fire conditions. Its design must not only meet fire protection code requirements for power supply reliability, fire resistance duration, and line protection, but also reasonably control project cost while ensuring safety. However, many projects tend to over-design fire protection power distribution, configuring all fire protection loads uniformly to the standard of specially important loads within Class I loads with dual redundant power supply circuits, resulting in a significant increase in cable usage. From the root cause of the problem, designers lack a refined understanding of fire protection load classification standards. GB 50016 and GB 50052 classify fire protection loads into Class I, Class II, and Class III loads, and fire protection equipment of different classes has different reliability requirements for power supply sources. For example, key fire protection equipment such as fire pumps, smoke control and exhaust fans, and emergency lighting belong to Class I loads and require dual-source automatic transfer power supply, but many designers indiscriminately configure all terminal fire protection equipment with dual-circuit terminal transfer at the highest class. From the perspective of codes and standards, GB 50052 has clear technical definitions for load classification. From an operational impact analysis, overly redundant fire protection power distribution design brings several negative effects. First, cable trays occupy more shaft space, potentially encroaching on installation space for other pipelines. Second, dual-circuit cables have higher fire protection requirements, and the unit price of mineral-insulated cables is 3-5 times that of ordinary flame-retardant cables. Third, excessive distribution boxes and cables increase future maintenance and repair workload. From cost data, for a large commercial complex of 100,000 m², by optimizing the fire protection power distribution scheme and changing non-critical fire protection equipment from dual-circuit terminal transfer to trunk-type or chain-type power supply, approximately 15%-25% of cables can be saved, reducing fire protection electrical cost by approximately 2-3.5 million yuan. The core measures to solve such problems include sorting out the load classification of various fire protection equipment at the early design stage, adopting differentiated power distribution schemes for fire protection loads of different classes, and optimizing the location of dual-power transfer points. From the perspective of engineering management as a systems engineering approach, solving this problem requires coordinated advancement across four dimensions: institutional design, process control, technical support, and culture building. At the institutional design level, clear responsibility boundaries and operating procedures must be established, translating code requirements into executable job responsibilities and work standards. At the process control level, full-lifecycle quality supervision and dynamic correction must be implemented to ensure that the work results of each stage meet expected goals. At the technical support level, information-based methods and intelligent tools should be actively introduced to improve management precision and efficiency. At the culture building level, quality awareness and compliance awareness must be cultivated among all staff to create an organizational atmosphere pursuing excellence. Only by organically combining these four dimensions can the quality common problems and management chronic issues that repeatedly occur in engineering construction be fundamentally solved, achieving continuous improvement and excellent performance in project management.
