Atkins is working on a major expansion plan for Hong Kong International Airport (HKIA).

We are working with the Airport Authority Hong Kong to implement a three-runway system (3RS), involving construction of a new airport platform north of the existing north runway. Our scope of works includes the design of the ground improvement works, reclamation, seawalls, re-provisioning works and the extension and modification of existing large box culverts. The size of the reclamation will be approximately 650 hectares - about half the current size of the airport platform.

The main challenge of the project is that no dredging of the soft sediments is allowed because of environmental concerns. Our key task is to develop cost-effective methods to strengthen the soft sediments in-situ such that the post-construction settlements are limited to acceptable values. A follow-up field trial will be conducted to confirm the performance of the treated seabed using the Deep Cement Mixing (DCM) technique.

The detailed design will be delivered within a tight schedule to facilitate the anticipated award of the main works contract in 2016. Our services will continue into the construction phase with the provision of design support services.

Upon completion of the 3RS, the expansion plan will allow the airport to handle an additional 30 million passengers a year according to the Airport Master Planning of 2030.
