SIA Hangars 4 & 5 was awarded to Lend Lease in October 2002 on a design development and construct basis. The two hangars are intended mainly for maintenance, repair and overhaul activities.
These hangars were supposed to be completed by 31 Dec 2003 on a fast-track basis. However, when SARS outbreak hit Singapore in Mar 2003, Singapore Airlines, which owns SIAEC, was badly affected financially. SIAEC then instructed Lend Lease to drastically reduce the scope of the project with minor ancillary structure and hangar floor slab only.
By December 2003, the whole economic situation within Singapore Airlines Group recovered remarkably.
The project was reinstated and Lend Lease was instructed to complete all remaining scope of works.
Hangar 4 is designed with a shorter height for nose-docking into the hangar whilst Hangar 5 taller and is tail-docking and shall be designed for future conversion to a paint hangar.
Spanning 90m from column to column, both hangars are able to accommodate the B777-400 aircraft.
The scope of works includes the co-ordination with the Employer’s direct sub-contracts comprising the cranes, tele-platforms, docking system, vacuum installation, 400 Hz electrical power, etc.
The 21,000 square metres project was handed over in two phases. Hangar 5 was completed in December 2004 and the remaining works were completed and handed over in Mar 2005.
