The Robert Bird Group has been engaged by the Leighton Contractors (Asia) & Chun Wo Joint Venture to assist with the development of the roof erection methodology, design of the permanent works structural steel roof connections and temporary works solutions for the new Passenger Clearance Building (PCB) in Hong Kong.

The Passenger Clearance building forms part of the Hong Kong Boundary Crossing Facility (HKBCF), which will provide clearance facilities for passengers and vehicles entering or leaving Hong Kong via the new Hong Kong Zhuhai-Macao Bridge.
The PCB project involves reclamation of approximately 130ha of land from the open waters to the northeast and directly below the flight path of the Hong Kong International Airport and construction of a number of buildings and transport facilities on this artificial island to provide passenger and cargo clearance services.

Key technical challenges

  • The primary tower structure consists of a composite slab and beam structure. Due to the long beam spans and thin slab, extensive analysis for footfall vibration was required to ensure the structure achieved code requirements and client expectations.
  • Working with the existing structure and developing design solutions that strengthened rather than demolished.
  • Extensive co-ordination with the mechanical engineer to develop a strategy that minimised beam penetrations and beam notches.
  • Differential shortening analysis with consideration of mega truss, steel structure, concrete structure and existing structural elements

Environmental performance

  • 5 Star Greenstar
  • 5 Star NABERs Energy and 4 Star NABERs Water ratings.

Key technical challenges

The PCB project involves reclamation of approximately 130ha of land from the open waters to the northeast and directly below the flight path of the Hong Kong International Airport and construction of a number of buildings and transport facilities on this artificial island to provide passenger and cargo clearance services.

The PCB is to be the primary building of the HKBCF, comprising a single level basement, ground floor of approximately 39,000m2, three traditionally reinforced concrete structures, external facade/curtain wall and a two-way framed structural steel roof of approximately 60,000m2 in an area supported on 50 concrete columns spaced on a 42m x 33/30m Grid.

RBG’s primary role on the PCB project is to provide specialist engineering services to develop an erection methodology which was suitable for the site.

The major items to be considered for the site are:

  • Air Height Restriction ~1m above the steel roof.
  • Short construction programme
  • Space limitations and site access.
