Toyo Construction Co., Ltd. (President: Kyoji Takezawa) has recently developed a “Crane Camera Image Detection System” which utilizes crane camera movie images.

This system has a crane camera installed at the tip of the crane boom and workers can be detected from the camera movie images by image recognition technology, and the crane operator is notified when a worker gets close to the suspended loads.

During crane operation, the operator performs operations such as lifting and hanging loads according to instructions of the signaling person. But depending on the environment of the work place, the crane operator cannot visually check the hanging location directly. The use of crane cameras is effective because they can be viewed through a TV monitor during work at places where the crane operator cannot see. On the other hand, since it is an image from the upper side of a suspended load, people tend to be seen smaller and there is a possibility that the operator’s attention may focus on suspended loads and installation locations and that the recognition of people will be delayed.

By registering the model (color) of the object, this system can detect and track multiple numbers of workers at the same time. When it detects a worker that has intruded into the set area, a red colored frame is displayed on the monitor, a warning light is lit, and the danger is reported to the crane operator. Because it is possible to detect workers even if the camera installation position, orientation and focal length are changed, a safe crane operation is possible more than ever.

We will continue to make use of technologies such as ICT and AI to strive to develop technologies that contribute to improving work efficiency, productivity and safety management.

Toyo Construction Co., Ltd. (President: Kyoji Takezawa) received a tender for “Package 1 Mombasa Port Container Terminal Construction Project” from Mombasa Port Development Project Phase 2 tendered from the Kenya Ports Authority.
The signing ceremony was held on March 12th. The tender value is about 13.5 billion yen with a construction period of 38 months and is scheduled to be completed in 2021.

As in Phase 1, which was the first project we received the tender from Africa and was completed in February 2016, this project will be carried out with the implementation of STEP (Special Terms of Economic Partnership) which is part of a loan assistance provided by the Japanese government through the Japan International Cooperation Agency (JICA).

For this project, Japan’s high port construction technology is required such as soft ground countermeasures.

Mombasa Port is the largest commercial port in East Africa and plays an important role as a gateway to the “northern corridor” connecting neighboring inland countries such as Uganda, Rwanda and Burundi. Due to the remarkable economic development in recent years in the region, the container handling volume at the port has increased sharply (2002: 300 thousand TEU *, 2015: 1.07 million TEU), and because a demand exceeding 2.6 million TEU is expected by 2025, we are planning to further upgrade the port capacity by improving the new container yard and quay, following the Phase 1 project (With a handling capacity of about 550,000 TEU).

Main constructions involve pier type quay (depth 15 m, length 250 m) connected to a container terminal built during the Phase 1 project, construction of a container yard of about 17 ha (including landfill and ground improvement works) and construction of 16 buildings. After completion, it is expected that the improvement of capacity to receive containers equivalent to about 500,000 TEU per year will be improved.

We have completed construction of Phase 1, which is the largest port project in East Africa and tendered in 2011, within the scheduled construction period contributing to economic development not only in Republic of Kenya but also in the East Africa region as a whole. In addition, we have received high praise for actively handing down Japan’s advanced construction technology such as strict safety and quality control, operation of construction machineries, and welding, to the Kenyan engineers. For this project, we will continue to unite the company’s technological capabilities together and continue to work by making full use of our experience and achievements that we have gained in Phase 1 projects. We will contribute to this economic development by implementing further technological transfers and will contribute to “high quality infrastructure investment” to achieve sustainable development goals (SDGs) promoted by the Japanese government.

A joint venture of Toyo Construction Co., Ltd. (President and Representative Director: Kyoji Takezawa), Wakachiku Construction Co., Ltd. (President and Representative Director: Ryohei Ioroi) and a local nationally-owned Indonesian construction company, PT Adhi Karya Persero Tbk (ADHI), has been awarded the contract for “Package 2: Breakwater, Seawall and Channel Dredging Works” as part of the Patimban Port Development Project, Phase I ordered by the Directorate General of Sea Transportation (DGST) of the Ministry of Transportation, Republic of Indonesia. The contract signing ceremony was held on November 30, 2018. The contract amount is approximately ¥13 billion (total for joint venture), and the construction period is 24 months.

Under the ODA loau scheme (yen loans) provided by the Japanese government through the Japan International Cooperation Agency (JICA), Special Terms of Economic Partnership (STEP) will be applied in this project, in which Japan’s high port and harbor construction technologies are required.

Sea transportation is a main means of transportation in Indonesia, which consists of more than 17,000 islands. However, with the rapid increase in freight flows accompanying the country’s rapid economic growth in recent years, delays in logistics due to a shortage of absolute capacity in port and harbor facilities is a concern, and in 2025, it is expected to be impossible to handle the increase in container demand with only the Port of Tanjung Priok in the Jakarta Metropolitan area. Therefore, it is hoped that the construction of the new port in Patimban in the eastern part of the metropolitan area will contribute to strengthening the logistics functions of the metropolitan area, as well as additional economic growth through improvement of the investment environment in Indonesia.

The main work of this project consists of construction of a bamboo foundation gently-sloping type breakwater (1,930 m) and a sheet pile seawall (6,921 m) surrounding the outer periphery of the new port and dredging of the outer navigation channel (909,973 m³).

The order for this construction work was based not only on price, but also on a high evaluation of the technologies of the joint venture and actual results in overseas projects. By concentrating the technical capabilities of the partner companies working together in the project, and completing the construction by making full use of their experience and track records, Toyo Construction and its partners will contribute “high quality infrastructure investment” for the economic development of Indonesia and achievement of the Sustainable Development Goals (SDGs) being promoted by the Japanese government.

Toyo Construction Co., Ltd. (President and Representative Director: Kyoji Takezawa) has received an order for “Flood Risk Management Project for Cagayan de Oro River Contract Package 2” from the Department of Public Works and Highway (DPHW) of the Republic of the Philippines, and signed the contract on February 12 of this year. Among ODA loan scheme (yen loans) which the Japanese government provides through the Japan International Cooperation Agency (JICA), a general yen loan is applied in this project. The value of the order is approximately \5.9 billion, and the construction period is 36 months.

The Philippines is one of the countries with the largest number of natural disasters in the world. In December 2011, Typhoon Sendong struck directly in the center of the Northern Mindanao region, causing enormous damage, which affected about 1.17 million victims and resulted in approximately 1,250 deaths.

Among this damage, because adequate flood countermeasures had not been taken until now in Cagayan de Oro, a major city located in the lower reaches of the Cagayan de Oro River, flash floods caused by Typhoon Sendong devastated communities along the river.

In this project, levees and retaining walls in the Cagayan de Oro River basin will be constructed or repaired, etc. In addition to mitigating flood damage in the river basin, the project is also expected to contribute to the stable economic and social development of the region.

The main scope of the work is construction of 2.3 km of river levees. However, because the work zone adjoins a residential area, it is necessary to minimize the effects of the construction. Japan’s high construction technologies are required in order to achieve this, and the static sand compaction pile construction method, which is a Japanese technology, has been adopted.

Toyo Construction received this order based on a high evaluation of the company’s construction capabilities and many actual results of projects in the Philippines. The company intends to complete the project by demonstrating its technical capabilities to the fullest possible extent, and contribute to “Quality Infrastructure Investment” for the economic development of the Philippines and achievement of the Sustainable Development Goals (SDGs) being promoted by the Japanese government.
