Yongnam Holdings said its subsidiary Yongnam Engineering & Construction has secured $54.3 million worth of subcontract works, involving more than 10,000 tonnes of structural steelwork.

In the first subcontract, Takenaka Corporation awarded Yongnam a subcontract for structural steelwork at the upcoming Changi International Airport Terminal 4.

The scope of work involves the supply, fabrication, surface treatment, delivery and erection of structural steelworks of the roof structure, certain parts of the internal floors as well as the link bridges, canopies and other appendages of the new airport terminal.

Yongnam is expected to commence site works in the third quarter of 2014 and the new airport terminal is expected to be completed in 2017.

For the second subcontract, Samsung C&T Corporation awarded Yongnam the structural steel subcontract in the redevelopment of the UIC Building along Shenton Way, Singapore.

This project is a mixed development and comprises a new 23-storey office tower and a new 53-storey residential tower complete with a seven-storey podium and two basements.

Yongnam will supply, fabricate, surface-treat, deliver and erect the steel structure required in the construction of the development's residential and office towers.

The entire redevelopment is expected to be completed in 2017.
