Hydraulic engineering: three new contracts in Cambodia and Vietnam
27 novembre, 2017
Following its delivery of the extension to the Niroth plant in Phnom Penh in early 2017, this summer VINCI Construction Grands Projets signed a further contract for the Cambodian capital with PPWSA, the Phnom Penh water authority.
This concerns the renovation of the Chamkar Mon water treatment plant, valued at some €21 million. Teams have been working since September on the demolition of the existing plant, prior to the design-build phase for the new plant which will see the production of drinking water there increase from 20,000 to 52,000 cu. metres a day. The works will take two years.
A second contract, worth about €8.8 million, was also signed this summer, with SRWSA, the water authority in Siem Reap, for the city’s water treatment plant. It covers the design-build of a water intake structure (30,000 cu. metres/day), increasing the existing plant’s drinking-water production capacity by 15,000 cu. metres/day and the laying of a 6.5 km-long connecting pipe. In total, 14 months of works and a four-month commissioning period have been scheduled."
In Vietnam, meanwhile, August 2017 saw VINCI Construction Grands Projets secure, together with Bessac (Soletanche Freyssinet), the design-build contract for the construction of a 10 km-long pipe to supply treated water to the centre of Ho Chi Minh City, the country’s economic capital.
Valued at some €60 million, it covers the detailed design of the project, the manufacture of the prefabricated pipe elements in reinforced concrete (external diameter: 3 m) and their installation using the pipe jacking technique, and the creation of 16 shafts, 11 connections and 5 branch sockets for future connections to the network. Lasting three-and-a-half years, this project will rely on the combined expertise of VINCI Construction Grands Projets in the management of hydraulic projects and Bessac in the field of micro-tunnelling.
Over the last five years, the structures created worldwide by VINCI Construction Grands Projets have made possible the production of a million cu. metres of drinking water a day.
