NORTHERN MARMARA MOTORWAY PROJECT CRITICAL ISSUES STRONG QUALITY CONTROL BY ICA ON HSK EXECUTION Quality control In these last months a strong quality control has been done by ICA on HSK execution, particularly on the slip form and concrete interaction during tower execution. Prof. Rossetti has brought his experience concerning the exact point of the concrete setting related to the slip form speed.
