How often is the DOTD Inspector required to visit the contractor's plant when it is producing concrete for a DOTD project?

The requirement for a DOTD Inspector to visit the contractor's plant daily when concrete is being produced for a DOTD project is grounded in the necessity for quality control and compliance with specifications. Regular daily visits allow inspectors to closely monitor the production process, ensuring that the materials used, the mix designs, and the overall production practices align with the standards set forth in the project specifications.

Daily inspections help in quickly identifying any issues or discrepancies that might arise during production. This proactive approach is vital for maintaining the integrity and quality of the concrete, which is critical for the longevity and safety of the constructed infrastructure. Moreover, it allows for immediate corrective actions if any deficiencies are observed, thereby reducing the risk of potential failures in the finished product.

Other frequencies of inspection, such as weekly or monthly, would not provide the same level of oversight and could lead to problems going unnoticed for extended periods. Annual inspections are insufficient for monitoring the ongoing production of concrete, as there would be too much potential for variability in quality during the time between visits. Thus, the daily inspection requirement is essential to uphold concrete quality in DOTD projects.
