by the JV teams and applied to the site works and construction management processes for the project. A Quality Plan was developed for the project and approved by the Engineer. The basic approach involved development of detailed method statements for each activity. Quality control inspections were undertaken and the completed work inspected by the RE for acceptance on behalf of the client. The project risks were addressed prior to commencement with a full risk assessment and determination of mitigation measures developed. A risk register was prepared and the risks to achieving the required milestones and standards, health, safety, environment and the achievement of the employer’s considered by the site team. With a pre-construction ADT of 14 566 vehicles per day the disruption to and safety of road users was a major risk and the provision of concrete NJ barriers ensured the live lanes were kept clear and vehicles were not at risk of being struck by boulders. Rock falls and debris coming off the slope and endangering the safety of workers and road users or causing damage to vehicles and construction plant. The stability of the existing slopes was a risk uppermost in the site team’s assessment of risks and the Engineers had identified problem areas in three of the five construction zones. With the N2 to remain open to traffic at all times, albeit with occasional lane closures, the possibility of slips and rock falls from the slopes was a significant hazard and the risk to passing traffic was monitored throughout the project. Working space, particularly for the telehandlers, MEWPs and the soil nailing rig, was a concern however SANRAL permitted a lane drop to provide working space for this particular activity. This
caused some traffic delays but these were well managed by the specialist traffic control subcontractor. The varying nature of the in situ material in the cut slopes also meant that runoff due to heavy rainfall had to be closely managed. This was achieved by cutting temporary interceptor drains along the top of the two cut slopes in the position of proposed permanent concrete and stone-pitched cut-off drains. The team was lucky with the weather and this risk was not fully realised. Strong winds were a constant issue for the site teams and protocols were enforced to ensure site staff exercised care at all times, especially in exposed positions on the slopes. Working at heights, particularly when barring down loose material was a significant risk but the installation of life lines and the rope access team meant the risks were mitigated to acceptable levels.
