HONG KONG ’ S THREE-RUNWAY SYSTEM
commenced on August 1 2016 which involves formation of approximately 650 hectares of land . The construction work will be completed in phases for subsequent construction of new runway , taxiway system as well as a Third Runway Passenger Building with over 50 parking positions . Thorough research and study have been conducted before the construction . AA has an all-round management approach that closely monitors progress and considers major risks and timely intervention to make sure the project remains on schedule .
What challenges will the project face ? How will the project affect the environment and what measures are in place to offset any impact ? 3RS project is expected to take eight years to complete . The major challenge is to complete the project on time and within budget .
Environment protection is one of the core values of HKIA . In accordance with the requirement in the Environmental Permit ( EP ), AA has undertaken the Environmental Impact Assessment ( EIA ) as an integral part of 3RS project , which consists of a series of studies assessing the potential environmental impact across 12 key aspects such as air and water quality , noise , terrestrial and marine ecology .
AA has adopted over 250 measures proposed by the EIA report to mitigate , avoid and reduce the potential impact to environment . The 3RS buildings will incorporate a range of green and sustainable features in their design , construction and operational aspects .
One of the challenges of the reclamation is that part of the site resides on contaminated mud pits . Advanced reclamation method such as the first adopted deep cement mixing was introduced as engineering solution to mitigate and avoid the impact to the environment . Meanwhile , horizontal directional drilling for submarine aviation fuel pipeline diversion will be adopted to avoid disturbance to seabeds .
Recycled materials will be used when possible for 3RS ’ s building and facilities to implement principles of reducing pollution , reusing and recycling of waste .
The design of 3RS terminal is
