Oct 30, 2014

Penta-Ocean Construction Co., Ltd. and Koon Construction & Transport Co Pte Ltd (Penta-Ocean/Koon JV) have been awarded the LAND PREPARATION WORKS FOR AIRPORT DEVELOPMENT by The Ministry of Transport, Singapore recently. The awarded amount is about ¥95.3 billion (S$1,108 million) and it is scheduled to be completed by 2020. Of this, the amount awarded to the company is about ¥76.2 billion.
The last project undertaken by Penta-Ocean at the Changi Airport was in 1976 for the airport reclamation works, and it is about forty years later that Penta-Ocean is now back at Changi Airport.

The project is for 600 ~ 700 hectares of preparation work for the future expansion of the Airport and extension of existing Runway 3 which will be constructed on 1,080 hectares of reclaimed site.
According to the media release made by the Ministry of Transport , the Changi Airport is aiming to be one of the largest terminals in the world.

Since entering the Singapore market in 1964, the Company has participated in numerous large-scale projects in the country. The Singapore government has presented a policy in which the functions of Changi Airport as a regional hub airport will be strengthened to form the basis for the country’s development. The Company considers Singapore to be one of the key markets for its overseas business – and backed with a wealth of experience in the field – the Company will continue to proactively expand the business while keeping an eye on the bottom line.
