Office Tower, Hong Kong International Airport, Hong Kong

NEC Users' Group silver member Airport Authority Hong Kong (AAHK) has used NEC to procure a major new office building in the middle of Hong Kong International Airport. The seven-storey structure has provided much-needed additional accommodation for AAHK and a new headquarters for Aveseco, an aviation security company jointly owned by AAHK and the Hong Kong Special Administrative Region Government.

AAHK let the HK$794 million (£77 million) design-and-build works to contractor Dragages in June 2019 under an NEC4 Engineering and Construction Contract (ECC) Option C (target contract with activity schedule). Despite the onset of the Covid-19 pandemic, the building was topped out in April 2021 and completed on time and budget in January 2022. It was highly commended for the 2021 NEC Building/FM Project of the Year award.

Designed by architect Ronald Lu and Partners, the 12,000 m2 glass-clad building is located in a taxi staging area near the entrance to Terminal 1. The site is constrained horizontally by two curved flyovers, with an elevated section of Cheong Hong Road to the west and an MTR Airport Express viaduct to the east, and vertically by airport height restrictions.

It was AAHK's third NEC contract following successful use of the NEC3 and NEC4 ECC Option D (target contract with bill of quantities) for civil engineering works on the HK$141 billion (£14 billion) new third runway project, which is due for completion in 2024. These include the new north runway pavement and 2.2km of tunnels for a new automated-people-mover and baggage-handling-system.

Dealing with uncertainty

SS Kong, general manager of AAHK's Capital Works Construction Department, says NEC was chosen to procure the new office building due to site constraints and uncertainties about buried assets and traffic planning.

'The building foundation was very close to substantial underground utilities that could not be accurately located in the planning stage. It was also unclear how construction works would impact on traffic management within the existing taxi staging area. Due to these and other planning uncertainties and constraints, we decided that ECC Option C would be a desirable procurement method, with the client and contractor collaborating to develop solutions that would ultimately benefit both parties.'

Kong says that in following the NEC obligation to work in a, 'spirit of mutual trust and co-operation', the client and contractor demonstrated a willingness to work towards achieving mutual project objectives. 'Both teams discussed, compromised and took action with an open-minded attitude in the NEC contract processes for early warnings, compensation events and budget and programme control.'

He says the contractual arrangement provided the client with full transparency of the contractor's progress and expenditure. 'It also offered more opportunity for the project manager to manage risks, develop alternative solutions and minimise the impact of any changes on programme and cost.' Kong adds that the NEC pain/gain share mechanism provided a common objective for the contracting parties to undertake the works with better cost control, quicker turnaround and more efficient operation.
