Port Moresby Sewerage System Upgrading Project［Papua New Guinea］
- In this project, a full-scale large sewage treatment facility and a sewage piping network were built for the first time in Pacific island countries. The project has helped curb the outflow of untreated sewage water into to the ocean, mitigating the serious social problem of environmental destruction and preventing local residents from getting water-related diseases.
- The project was aimed to build a sewage treatment facility capable of treating 14,800 cubic meters of sewage water per day in a coastal area, along with a 1.6-kilometer ocean outfall pipe and a sewage piping network whose total length is approx. 21 kilometers (trunk: 12 kilometers; branches: 9 kilometers). It also involved repairing and constructing a total of 13 sewage pump stations. Using Japan‘s construction technology and management technique, high-quality facilities were completed safely at low cost within the construction period.
- The project has made it possible to treat sewage water from a densely populated coastal area of Port Moresby City, home to approx. 90,000 people, thus enabling improvements in the marine environment and the sanitary conditions for local residents. The project adopted an activated sludge process (oxidation ditch process), which allows relatively low-cost operation and maintenance, and was the first sewerage system project to which the Special Terms for Economic Partnership (STEP) were applied.

- Improvement in ocean pollution also prevents the spread of water-related diseases in the coastal area. Sewage water is treated with ultraviolet rays, not chlorine, and released offshore through an ocean outfall pipe to reduce the impact on the marine environment.
- To reduce the construction and operation costs, the activated sludge process (oxidation ditch process) was adopted as the treatment method. The treatment facility differs in height, and the gravity-based natural flow-down method is used to save energy.
- A piping network was built through the active use of existing pipes and pump stations. The newly installed trunk sewer whose total length is 12 kilometers uses high-density polyethylene pipes (HDPE) having high durability and high corrosion resistance, which helps cut operation costs.
- For the one-year period after the start of operation, Japanese instructors train personnel and engage in technology transfers to ensure that the facility is run stably.

Maintenance and Rehabilitation Project of First and Second Bosphorus Bridge［Turkey］
- IHI Infrastructure Systems Co., Ltd. has conducted large-scale repair work of the First Bosphorus Bridge (span length of 1,074 m; completed in 1973; constructed by a British company) and Second Bosphorus Bridge (span length of 1,090 m; completed in 1988; constructed by the applicant), which connect the Asian and European sides of Turkey.
- First Bosphorus Bridge was deteriorated due to its age, and therefore they replaced all the 240 diagonal hangers with vertical hangers. This kind of replacement work was the first attempt in construction history, and they were able to complete the work without the full traffic closure. This work was carried based on a recent research, which proves that diagonal hangers tend to inflict greater damage on the bridge girders than vertical hangers.
- To reinforce the suspension bridge’s main cables, they used reinforcement strands, and this process was almost unprecedented. At the same time, they implemented preventive maintenance by installing dehumidifiers and an automatic humidity control system to prolong the life of the suspension bridge at a lower cost.

- 40 years have passed since the construction of First Bosphorus Bridge (25 years for the Second Bosphorus Bridge) and for this reason, the initial traffic capacities of these bridges were over exceeded up to the level where restriction on heavy vehicles were necessary. They have successfully achieved in reinforcing these two bridges with the unique technologies, which also resulted in decrease of cost.
- Their past maintenance experience and achievements in Turkey, which include the “First Bosphorus Bridge Soundness Evaluation Project” and “Seismic-Reinforcement Project on Second Bosphorus Bridge and Large Scale Bridges in Istanbul” were highly evaluated in Turkey, and therefore they were able to be awarded as a contractor of this project as well.
- The demand of maintenance and reinforcement work of large scale bridges is keep growing in both Japan and Turkey, hence, they have been putting great efforts on acquiring know-hows on maintenance work and developing skills of young engineers for the purpose of fulfilling these demands.
Noguchi Advanced Research Laboratories［Ghana］
- This project involved the construction of a medical research institute with state-of-the-art research facilities in Ghana, West Africa. This country has close ties with Dr. Hideyo Noguchi. During the current COVID-19 crisis, the institute has also been playing a key role in research into infectious disease control in the local community, thus making a major contribution to society as a whole.
- Within the Noguchi Memorial Institute for Medical Research, which was established in 1979 using Japanese ODA, a cutting-edge infectious disease research center devoting itself mainly to infectious disease research was constructed through the grant ODA project. This newly constructed research center is equipped with BSL3 laboratories, PCR laboratories, and laboratories dedicated to immunology, virology, and bacteriology.
- In this area, with its hot and humid climate and frequent dusty seasonal winds, high-quality supervision and administration were applied during the construction phase, by establishing procedures involving the installation of high-performance HEPA filters for the construction, and carefully checking workers’ entering to and exiting from the laboratory.
- The laboratories have acted as an international base for countering the novel coronavirus infections in West Africa, conducting 80% of the medical tests for the infections in Ghana and about 50% of those in countries around West Africa during the initial stages of the spread of the infection around Africa.

- The application of laboratory design and construction technologies, developed by Japanese companies inside and outside the country, has contributed to the provision of a quality infrastructure.
- Japanese technologies were applied—as an example, the BSL3 laboratories where precise air conditioning control is required were constructed with procurement from Japanese companies. In the selection of materials, not only initial cost but also quality, ease of maintenance, and the degree of aftercare services were considered prior to the implementation of the procurement plan. Japanese staff were on site from importation to installation while attention was given to ensure that no problem would occur after the start of the operation through the continuous provision of aftercare services.
Tank Hill Park with Yamasen Japanese Restaurant［Uganda］
- This was the first project in Uganda in which a Japanese company had been responsible for all the activities from construction to operation, using only funds from the private sector. Although they did not have enough materials or human resources and had only a limited budget, TERRAIN architects and Cots Cots were able to successfully transfer Japanese technology to complete the construction of a commercial facility that local people hold in high regard.
- This project involved planning, designing, and constructing of a complex commercial facility with Japanese restaurants and other tenants in Kampala, the capital of Uganda, a landlocked country in East Africa.
Site area: 3,371m2
Total floor area: 785m2
Structure: Mixed construction using wood and reinforced concrete
- They successfully used eucalyptus wood, the cheapest and most versatile material in the area, as a structural and finishing material by carefully drying and treating it. They also used materials and building methods that are native to the area such as a thatched roof and fired bricks.
Period：From January 2017 to August 2018

- While it is common for an overseas workforce and imported building materials to be used in large-scale projects, for this project they employed only one Japanese staff member. The remainder were all local people. The materials were procured locally as far as possible. Additionally, although eucalyptus wood is not normally used as a structural material despite its low cost and abundance, they were able to use it as a structural material by applying the wooden building techniques traditionally used in Japan.
- This facility is now held in high regard by both local and foreign people as an accessible facility where they can easily get together, despite it typically being difficult for foreigners and locals to mix in Africa. Since this facility was provided for common use, it has given opportunities for a Japanese restaurant and other tenants to utilize local ingredients and human resources and for a nursery established in the facility to help develop an environment where females raising children can comfortably use the facility or work, supporting continuous development in the area. In addition, this facility, including a tenant Japanese restaurant operated by the first Japanese chef in Uganda, is also working as a base for promoting Japanese culture.
