Abstract

Urban roads and bridges shoulder the dual missions of traffic operation and urban renewal. Their construction quality directly relates to structural durability, safe passage, and life-cycle costs. Currently, against the backdrop of rapid construction and complex environments, issues such as deviations in the implementation of design outcomes, imbalanced process coordination, fluctuations in material quality, and weaknesses in on-site management are prone to triggering quality risks. There is an urgent need to enhance the intrinsic safety and benefits of projects through whole-process control. Focusing on the above situation, this article sorts out key control factors from three aspects: pre-construction design control, dynamic construction process control, and supervision and inspection closure. It diagnoses problems such as the disconnection between design and construction, uneven capabilities of construction teams, lax material quality control, and disordered on-site organization. Subsequently, it proposes countermeasures including strengthening pre-construction quality planning and optimization, systematically improving personnel skills and work standards, establishing a sound material procurement and inspection chain, and perfecting on-site quality supervision and information traceability, aiming to construct an executable and quantifiable quality management system.
