ECC Option C now delivering half of Hong Kong’s Central Kowloon Route works

The Hong Kong Highways Department (HyD) has let a further NEC3 Engineering and Construction Contract (ECC) Option C (target contract with activity schedule) on the HK$42 billion (£4.2 billion) Central Kowloon Route highway project.

The latest award means ECC Option C contracts now total HK$13.9 billion (£1.4 billion), just under half the HK$28.9 billion (£2.9 billion) of works so far awarded on the project. Due for commissioning in 2025, the new 4.7 km dual three-lane carriageway will link the Kai Tak development in the east to west Kowloon (see Issue 102).

Worth HK$5.67 billion (£0.6 billion), the new contract was awarded in July 2020 to NEC Users’ Group member Gammon Construction Limited for construction of an administration building and three tunnel ventilation buildings in Yau Ma Tei, Ho Man Tin and Kai Tak. It includes provision of the tunnel ventilation system, air purification system, central control and monitoring system, fire services system and traffic control and surveillance system.

The 2.8 km long main tunnel section of the route was awarded to Bouygues Travaux Publics last July under a HK$6.23 billion (£0.6 billion) ECC Option C. Two months earlier an Alchmex−Paul Y joint venture started building the connecting roads at the eastern end of the tunnel under a HK$1.97 billion (£0.2 billion) ECC Option C.

Gammon chief executive Thomas Ho said, ‘We are delighted to be working with Highways Department again on this vital piece of infrastructure for Hong Kong. Building information modelling and innovative digital construction and asset management systems will be used to support a collaborative approach on the project.’
