Electrowatt Engineering, part of Finland’s Jaakko Pöyry Group, has been appointed to supervise construction of China’s Zhangjiuhe river water division and water tunnel project in Kunming.

The assignment coincides with the invitation for contractors to prequalify by 21 May for the project’s three tunnelling contracts that together total 21.5km. A separate contract will be awarded for inverted siphon works.

The three contracts involve:

  • 304m Zhongwanchang tunnel, 622m Longhai tunnel, 1,619m Shimengkan tunnel, 2,908m Chawuqing tunnel, 5,505m Machang tunnel, together with pipeline works
  • 5,802m Xiaopingzi tunnel, 1,225m Maidichong tunnel and pipeline works
  • 4,921m Yanmeidi tunnel, 7,434m Fangergou tunnel and pipeline works.

    • All the tunnels will be built using drill and blast techniques and lined with cast in situ concrete. Completion is by mid-2005.

    The prequalification is being handled by the Beijing-based China National Metals and Minerals Import & Export Corporation and the Minmetals International Tendering Company which hopes to invite tenders in August.

    A set of prequalification documents for each contract costs US$480 and is available via email: wangdl@minmetals.com or zhaozhi@minmetals.com
