Urgent call for project rebid in Nepal

Melamchi Water Supply Development Board (MWSDB), Kathmandu, Nepal


The mountain country of Nepal has released an urgent call to international tunnelling contractors to pick up and complete a vital water supply project for the capital city, Kathmandu.
The Melamchi Water Supply Project centers on a tunnel of 27.5km long x 12.7m2 to deliver a design capacity of 510 million litres/day of water from the Melamchi River Valley to the Bagmati River in the Kathmandu Valley.
The project is funded by a loan from the Asian Development Bank.
Vital water supply tunnel for Kathmandu

Vital water supply tunnel for Kathmandu

In February 2009 construction was awarded to a Chinese construction joint venture. Drill+blast excavation since then has been unacceptably slow and of poor quality. On 25 September 2012 the contract was terminated.
Given the critical need for the water supply in Katmandu, the Melamchi Water Supply Development Board, the implementing agency for the Nepal Government's Ministry of Urban Development, the executing agency, is working to have the project rebid as soon as possible and the tunnel completed within a revised 36-month schedule.
The Engineer for the project is Pöyry AG, Pöyry Infra Oy and Hifab International Ltd in association with Multi Disciplinary Consultants (P) Ltd. Contractors need to be in a country that is a member of the Asian Development Bank.
Of the 27.5km tunnel, some 6.3km was completed by the previous contractor. Drill+blast is expected to be used to complete the tunnel although the actual method will be left to the discretion of the experienced and competent rebid contractors.
To expedite the rebid process, interested contractors are invited to visit the project during October 2012 to have suggestions and recommendations incorporated into revised contract documents for release of an invitation to bid in the second half of November 2012. An award of contract is scheduled for the first quarter of 2013.

Outreach for Norway's major rail tunnel project

Consultants and contractors are invited to Oslo on Wednesday 6 April to meet the project managers of Norway's largest rail infrastructure project to date, most of which is aligned in tunnel. "We want to notify the European market about the upcoming opportunities that the Follo Line presents," said Project Director for Jernbaneverket, the National Rail Administration, Anne Kathrine Kalager.
"Currently, tenders are out for several engineering contracts," said Kalager, "and the size of the project is expected to attract more firms from abroad than is usual for Norwegian projects. This is why we would like to notify the international market early on."
Contracts for design and construction of the 22km long high-speed railway running underground in twin tube tunnels between the suburban town Ski and the national capital Oslo are to roll out from the end of this year and towards a targeted opening date in 2018.

As well as introducing the project to the international design and tunnel construction industry, the Administration is interested to know of solutions, technical innovation, resources and competencies that international companies have to offer. "We need to familiarize ourselves with the railway market abroad," said Kalager.
Both drill+blast and TBM tunnelling will be considered for excavation of the 19km long twin tube running tunnels and major works are to be undertaken at the Oslo Central station as well as for a new station at Ski.
"We are looking forward to receiving interest from abroad," says Kalager. "With multiple contracts coming up, our goal is to choose the best engineering companies and contractors for the Follo Line." To date a Danish company and two Swiss firms are working with Norwegian firms to progress development of the project.

Plan of the Waller Creek

The Waller Creek Tunnel - Main Tunnel & 4th Street Creek Side Inlet Project is estimated at $40 million and consists of construction via conventional methods, of a flood control (main) tunnel from Waller Beach to Waterloo Park along Waller Creek, and two connector tunnels to capture intervening drainage at 4th/5th Street and 8th/9th Street. The main tunnel is about a mile long (1.6km) and consists of three segments of 20.5ft to 26.5ft (6.25-8m) finished diameter tunnel. Segment 1 is 26.5ft finished diameter and extends from the Outlet Structure (to be built under separate contract) approximately 2,275ft northward and includes a 100ft transition to Segment 2. Segment 2 is a 22.5ft finished diameter tunnel and extends about 1,570ft northward, including a 100ft transition to Segment 3. Segment 3 is a 20.5ft finished diameter tunnel and extends about 1,490ft northward to connect to the Inlet Structure (to be built under separate contract).
The 4th/5th Street connector tunnel is 22.5ft in diameter and extends eastward approximately 223ft from the tie point at the main tunnel to the 17ft i.d. 4th Street shaft. The 8th/9th Street connector is a 22.5ft i.d. tunnel and extends eastward for about 40ft. This work also consists of constructing a creek side inlet and debris screening structure within the east bank of Waller Creek and about 280ft of creek restoration between 4th and 5th Street.
