Revised schedule for Hawaii sewer tunnel RFQ
Owner:City and County of Honolulu, Hawaii, USAProject:Kailua-Kaneohe Tunnel ProjectStatus:RFQ due date 12 April 2013; Pre-bid meeting 9 May 2013; Bid due date 14 June 2013Information:Available on the City and County of Honolulu website
- Deadline for submitting requests for qualification for construction of the 3.2 mile (4.8km) long x 10ft-12ft (3m-3.6m) i.d. Kaneohe-Kailua Sewer Tunnel Project is extended by the City and County of Honolulu to 12 April 2013 with a pre-bid meeting rescheduled to 9 May and the public bid opening now planned for 14 June.
Alignment of the 4.8km long TBM sewer drive
- Designed by Wilson Okamoto Corporation and Jacobs Associates, the estimated $175 million project under the Oneawa Hills, in Oahu, Hawaii, is part of the Kaneohe-Kailua Wastewater Conveyance and Treatment Facilities Project that is being constructed by the City and County of Honolulu. The new tunnel will replace an existing 42in force main that is presently conveying wastewater from the Kaneohe Wastewater Pre-Treatment Facility to the Kailua Regional Wastewater Treatment Plant beneath Kaneohe Bay Drive.
- The tunnel is designed as a hard rock TBM drive working from an access shaft of about 75ft (23m) deep at the Kailua treatment plant site and ending at the 44ft (13.5m) deep shaft at the Kaneohe facility. Controlled blasting will be used for excavation of the working and reception shafts and the TBM starter tunnel. A new influent pump station will lift wastewater flow through the shaft to the surface treatment plant. The new influent pump station will be built under a subsequent construction contract.
Project presentation at NAT 2012
- About 95% of the route will be excavated through basaltic rock, with rockbolts, wire mesh and steel arch support installed as necessary. A fiberglass pipe backfilled into the tunnel will result in a finished i.d. of 10ft-12ft (3m-3.6m).
Deadline for RFQs - 12 April 2013. Bids due on 14 June.

Urgent call for project rebid in Nepal
Owner:Melamchi Water Supply Development Board (MWSDB), Kathmandu, NepalInformation:
- 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
- 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.

- 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. Download a pdf copy of the 6 April meeting invitation If you and your firm plan to attend send a notice to firstname.lastname@example.org before 21 March.

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.
Design of the flood control tunnel
