On September 17, 2020, CTII signed the Consultancy Services for the Construction Supervision of the Pasig-Marikina River Channel Improvement Project (PMRCIP), Phase IV, JICA Loan Agreement No. PH-P271 with the DPWH. For this project, CTII associated with Nippon Koei Co., Ltd., Woodfields Consultants, Inc., and Science and Vision for Technology Inc. The 7-year contract is led by Mr. Kazuto Suzuki as the Project Manager. The Consultancy Services will oversee and ensure the construction of the engineering facilities, implementation of essential non-structural measures, the transfer of technology to DPWH and other concerned agencies, and compliance with social and environmental safeguards. The project’s major works include channel improvement works for middle Marikina River from the downstream of Manggahan Floodway to Marikina Bridge Sto. Nino, construction of Manggahan Control Gate Structure, and construction of a floodgate and sluicegate at the joining sections of Cainta and Taytay Rivers to Manggahan Floodway. Japanese flood mitigation technology will be adopted in this phase geared to complement the completed works done under PMRCIP Phase II and Phase III. PMRCIP Phase IV is designed to complete a major scheme of DPWH to protect Metro Manila and its surrounding areas from flood damages and is covered by the Php 18.223-Billion Official Development Assistance signed by the Japanese Government and the Philippine Government on January 21, 2019.

In 2015, CTII was awarded the contract for Consultancy Services for the Construction Supervision of Flood Risk Management Project for Cagayan, Tagoloan, and Imus Rivers. The project led by Mr. Shuji Kaku as its Project Manager who is also the current Managing Principal of CTII Philippine Branch has completed the major works for Cagayan and Tagoloan Rivers in November and August 2019, respectively, while construction works on Imus River was extended up to October 2021.
The project, which is funded by JICA under its ODA facility and implemented by DPWH, includes construction/completion of Structural Measures and formulation/implementation of Non-Structural Measures (NSM).
Non-Structural Measures (NSM)
The non-structural measures, on the other hand, are aimed at reducing the vulnerability of the affected community residents to flood hazards. The NSM activities were planned and implemented in coordination with the Local Disaster Risk Reduction and Management Office (LDRRMO) of the target LGUs at the sub-project sites and the relevant government agencies such as the DOST-PAGASA and the Office of Civil Defense (OCD) at the national and regional levels. These activities included the conduct of QGIS Tutorials to update the local base maps, preparation and updating of flood susceptibility and spot maps, flood mapping and timeline survey after every major flood event, flood signages, assessment of evacuation centers, and conduct of IEC campaigns and flood drills for local officials, residents, and schoolchildren. A Flood Mitigation Committee (FMC), a coordination body, was also formed in each of the three (3) sub-project sites (Cagayan, Tagoloan, and Imus) to assist in handling issues and other concerns related to the Project’s pre-construction, construction, and post-construction stages. The conduct of quarterly FMC meetings is envisioned to help ensure the sustainability of the Project’s structural and non-structural measures in its O&M Stage.
