HAECO Base Maintenance Hangar

  • Year: 1998
  • Location: Chep Lap Lok, Hong Kong


The HAECO Base Maintenance Hangar is a 3 bay hangar capable of accommodating three 747 jumbo jets. The hangar was designed by Meinhardt C & S Ltd and consists of a four storey concrete structure which houses offices and workshops. The jets are kept fully undercover with a 70m x 210m cantilever roof. This roof is supported by pin connections to concrete shear walls as well as 6 box section steel masts and stays.

The main contractor for this project was Dragages et Travaux Publics (HK) Ltd with Cleveland Bridge initially responsible for the connection design as well as the supply, fabrication and erection of the 3,400te roof and gables. This included door header steel as well as crane and gantry runway support beams.

Cleveland were later awarded the assembly and erection of the hangar doors. In order to accommodate the tight tolerances required at the runway beams and door header steel, Cleveland engineered an erection scheme that allowed the assembly of the roof to be carried out at ground level. The roof was then strand jacked into position (with nine hydraulically linked 180te jacks) in two separate lifts, each weighing approximately 1000te, and connected to the permanent pins and stays.

This contract was completed on the scheduled date of 30th June 1998 at a total cost of £10 million on behalf of the Hong Kong Aircraft Engineering Co. Ltd.
