JTK Consult (JTK) was engaged by MMCEG – Gamuda JV (MGJV) to undertake a review of the on site concreting of the road tunnel construction with particular reference to long term durability considerations (ie) to achieve the overall project design life requirements. In this connection an on site survey of sections of the tunnels which had been cast was undertaken to confirm construction sequencing, the concrete being used and the nature of any site defects.
Based on Modelling studies, appropriate Concrete Technology Interventions were developed to improve quality and achieve the design intent.
The scope of work included an on site concreting review and pour operation plan, thermal modeling and concrete studies, on site QA/QC support and concrete trouble shooting for defects avoidance.
JTK consult enabled the Client to minimise the risk of defects during construction and to achieve the life cycle objectives. This provided a basis for managing the long term maintenance intervention.
