1 D runway of Tokyo International Airport DESIGN-BUILD PROCUREMENT SCHEME FOR THE EXPANSION OF THE TOKYO INTERNATIONAL AIRPORT Mitsuhiko OKADA The Overseas Coastal Area Development Institute of Japan (OCDI) Tama River D runway Tokyo Bay Tokyo International Airport (Haneda Airport) Background of the project Why was this project needed? When the expansion project was conceived: Busiest airport in Japan Caters for 55million passengers in 2000 (60% of the national total) Caters for 620 thousand tons of air freight in 2000 (66% of the national total) Provides 720 flights per day with three runways, linking with 47 airports in Japan 13 Nov 2012 CSIC-JSPS International Symposium 1

2 Haneda and the Metropolitan Area Haneda Airport in 2003 Haneda Airport West passenger terminal Runway A Runway B East passenger terminal (under construction) Runway C Need of further capacity expansion (Million) Haneda Airport Domestic Passenger Traffic The existing capacity was expected to be saturated in early 21 st century Preliminary survey was started in 2000 Re-expansion of Haneda and New-airport option were compared 9,000 8,000 7,000 6,000 5,000 4,000 3,000 2,000 1, Forecast Assuming that the expansion project will be completed between 2008 and (FY) 13 Nov 2012 CSIC-JSPS International Symposium 2

3 Haneda Airport Re-expansion Project Re-expansion of Haneda was found the most favorable option In 2001, the cabinet decided to construct a new runway of Haneda as soon as possible To make operational a 2,500m offshore runway and a taxiway bridge by the end of 2009 To increase the airport capacity by 50% and accommodate scheduled international flights Tama River Haneda Airport Expansion Project B-Runway 2,500m A-Runway 3,000m 多 摩 川 Connecting Taxiway C-Runway 3,000m Radio navigational aids New Waste Disposal Area Port of Tokyo New Runway 2,500m Challenges Completing the project before 2010 at a minimum cost Ensuring the smooth vessel traffic passing near the new runway Allowing the river flow to pass through the structure Protecting the environment of the adjacent residential area Alternative design concepts What were prospective designs? 13 Nov 2012 CSIC-JSPS International Symposium 3

6 Evaluation criteria of the Expert Panel Safe airport operation throughout the project life Resilience against natural disasters Reasonable costs and time for construction Safe and reliable construction works Environmental impacts Impacts on vessel navigation Conclusions of the Expert Panel October, 2002 No fatal flaws in the three concepts ( Hybrid, Pile-support, Float) Project concepts should be limited to the three concepts Design-Build procedure is recommended to find the most economical solution and fix the project costs as proposed in the bidding process Requirements for the D/B scheme Design-build scheme What was required? Requirement To accommodate three different design concepts To fix the life cycle costs Response Performance specifications covering three concepts Winning bidder will carry out the maintenance of the runway for 30 years with the costs it proposed if the government so requests To hedge engineering risks of novel design concepts Sufficient amount of long-term defect liability Design-originated risks should be basically taken by contractors 13 Nov 2012 CSIC-JSPS International Symposium 6

7 Requirements for the D/B scheme (2) Long-term maintenance Requirement To save project costs/government spending To ensure the project completion within the schedule Response Winning bidder is the one who proposes the minimum amount of project costs, the sum of the construction costs and 30-year maintenance costs Tender price should be lower than the predetermined target price VE is encouraged before and after the signing of the contract 8-15 corporations covering five engineering areas are allowed to form a JV in bidding Each JV member is required to have previous track records in the respective engineering areas The D/B contract includes an optional clause for 30- year maintenance to fix the life-cycle costs as proposed in the bidding process Bidders are requested to propose 30-year maintenance costs based on the 100-year maintenance plan in its technical proposal (Serviceable life is 100 years but obligating the contractor for 100 years is impractical) Long-term maintenance (2) Maintenance works are stipulated in the optional clause because (a) open tender is norm in the Japanese public procurement and (b) the government cannot conclude a contract without budgetary alllocation approved by the Diet (singleyear basis budget system in Japan) The government requests the contractor to carry out maintenance works if it finds no eligible competitor from engineering viewpoints (Conformity with the Agreement on Government Procurement (GPA)) Design-build scheme How did it play out? 13 Nov 2012 CSIC-JSPS International Symposium 7

8 Preparation Preparation (2) Ministry of Land, Infrastructure and Transport (MLIT) established a project team composed by: Civil Aviation Bureau Kanto Regional Development Bureau Project team prepared: Performance specifications Contract scheme Target price Technical specifications Site visits of pile-support runways (US, Portugal) Allowable movements of a floating runway (aircraft manufacturer) Specifications of new large aircraft (aircraft manufacturer) Anti-corrosion of 100-year durability Contract scheme Interview at the Utah State Government regarding the design-build scheme for I-15 (US$1.4billion) Timeline of the tender process Preparation of the upper limit price Process June 2004 Announcement of the contract scheme and performance specifications July 2004 Request for proposals September 2004 Notice of prequalification (experience records of similar projects) October 2004 Deadline of technical proposals February 2005 Notice of qualification (conformity to all the performance specifications is mandatory) March 2005 Bidding by qualified participants March 2005 Signing of the contract MLIT prepares designs/drawings for three design concepts and calculates D/B costs and 30-year maintenance costs The lowest D/B cost is determined as the upper limit for the D/B price The lowest total cost (D/B + maintenance) is determined as the upper limit for the total costs The bidder proposing the lowest total cost wins the contract on condition that its D/B price and total costs are lower than the respective upper limit 13 Nov 2012 CSIC-JSPS International Symposium 8

9 VE before bidding Cost saving efforts The bidder was allowed to propose additional VE before bidding on condition that its initial technical proposal was found conforming to The Specifications The JV proposed 43 VE proposals and MLIT approved 37 of them Bidding and project implementation Bidding and project implementation (2) JV s bidding price was within the upper limit MLIT and JV signed the contract at billion yen (approx. US$7.5 billion) in March 2005 Designs were carried out from 2005 to 2006 Start of on-site construction works was delayed until compensation to fishermen was settled Cost escalation due to the price increases of materials was reflected in the revision of the D/B costs D Runway started operation in October Nov 2012 CSIC-JSPS International Symposium 9

10 Contract including long-term maintenance MLIT concluded the contract with the JV at the D/B price of billion yen with the optional maintenance clause (14.9 billion yen for 30 years) The optional clause becomes effective upon fulfillment of the condition (No competitor from engineering viewpoint) The JV is carrying out maintenance works according to the contract Monitoring and maintenance Repair of bumps Bumps at the joint between decks and reclaimed area are monitored once a week at 20 points by 5-m interval Bumps are repaired before reaching 20 mm Observance of the slope limit After bump repair, longitudinal slope is made under 1.0 % by pavement overlay Monitoring and maintenance (2) Lessons learned Other major maintenance works (once in 30 years) Repainting of the inner surface of steel jackets to prevent corrosion Replacement of moisture controllers inside steel jackets Steel jacket Inside jacket Moisture controller Pros Cons Lessons Early completion and cost saving Project completion in 5.5 years with minimum cost escalation (12 %) Reliable maintenance The JV is carrying out maintenance works at the proposed price (14.9 billion yen for 30 years) For the project owner Preparation of the performance specification was timeconsuming and costly For the JV Preparation of the technical proposal was time-consuming and costly Recommendable for large-scale projects Compensation for proposal costs incurred by unsuccessful bidders would be fair 13 Nov 2012 CSIC-JSPS International Symposium 10
