What is often a consequence of not designing for adequate serviceability limits in concrete structures?

When concrete structures are not designed with adequate serviceability limits, one of the most common consequences is increased maintenance costs. Serviceability limits refer to the performance of the structure under normal usage conditions, focusing on aspects such as deflection, vibrations, and cracking. If these limits are not met, the structure may experience issues such as excessive deformations, which can lead to deterioration and require frequent repairs or enhancements, thus increasing overall maintenance expenses over time.

While higher initial construction costs, reduced load-bearing capacity, and improved durability might be considerations in design and planning, they do not directly relate to the immediate and practical repercussions that lack of attention to serviceability limits can have on ongoing costs and the functionality of the structure. Increased maintenance costs reflect the ongoing investment that must be made to keep the structure safe and operational, marking it as the most relevant consequence in this context.
