Abstract:The traditional extensive engineering management model has exposed many shortcomings in the renovation of old communities. Promoting refined management of construction projects is an effective approach to solving the difficulties in renovating old communities and implementing the requirements for high-quality development of urban renewal. The article combines a case of contiguous renovation of an old community in a central urban area in China to sort out an engineering management system that is suitable for the scene of the old community. Research has shown that refined management can significantly shorten construction periods, control project costs, improve project quality and resident satisfaction, and provide practical references for similar urban renewal projects and old community building projects nationwide.
