LiDAR Drone Survey, Msimbazi River, Dar es Salaam

By | Africa, All, Uncategorized

CDR International in association with Shore Monitoring and Research defined an integral full survey campaign for the lower basin of the Msimbazi River, which was executed last February. This World Bank funded survey project serves two purposes: 1) generation of reliable, accurate and fit for purpose bathymetric & topographic data of the Msimbazi River and its floodplains for riverine flooding related detailed studies, and 2) rigorous comparison of Digital Terrain Model (DTM) generation by Unmanned Aerial Vehicle (UAV; drones) Photogrammetry and UAV LiDAR. Traditionally LiDAR aerial acquisition methods for obtaining DTMs are done by planes. With the development of equipment, the LiDAR scanners are getting smaller and lighter, and drones can fly longer and can carry more weight, enabling to mount LiDAR scanner to drones. This potentially provides significant cost savings compared to both traditional LiDAR and field surveying methods. A meticulous comparison for the Sub-Saharan African context was however lacking. This study will recommend on when to use which surveying methods with respect to purpose, project area size, landuse/vegetation cover and challenges like import of equipment.
Preliminary insights of the analysis have been shared and presented recently at a master class at the Land and Poverty Conference 2019 – March 25-29, 2019 Washington, DC and at a workshop on DTM drone applications for Dar es Salaam stakeholders at World Bank Office in Dar es Salaam on April 11th, 2019.

The Msimbazi Opportunity Plan has been completed and has been signed by Minister of State Mr. Selemani S. Jafo of the President’s Office Regional Administration and Local Government. This is a very important next step towards implementation of the proposed interventions. CDR International is proud to have contributed to this World Bank funded innovative participatory design process as part of the Consultant’s Consortium.

NL.IN.BUSINESS – Laurens Poelhekke on Doing Business in Vietnam

By | All, Asia

According to Laurens Poelhekke (29) of CDR International, in order to be successful as an international entrepreneur, you have to be flexible and have a feeling for cultural aspects. But not only that; having a local network is essential. “And in Vietnam, being present in the country is very much appreciated.” We spoke to Poelhekke about doing business in Vietnam. How did he tackle that, where do you have to be as a Dutch entrepreneur and where does he think there are opportunities?

“Find a good local partner, put a lot of time in it. Build a good working relationship, and then doing business in Vietnam can go very fast! “

Laurens Poelhekke is South East Asia Representative / Civil Engineer in Vietnam for CDR International. He is also a board member of the Dutch Business Association Vietnam (DBAV). He now lives and works in Ho Chi Minh City. Since one and a half years he has been the forward post for South East Asia for the engineering firm in the hydraulic engineering sector. Twenty people now work worldwide for CDR International. “I am co-responsible for building and developing projects in Vietnam, Myanmar and Bangladesh. I am also a hydraulic engineering engineer for our projects. For example, I have worked on a project where six flood defences and seven kilometres of dyke have been built in Ho Chi Minh. CDR carried out a design review for the contractor. The city suffers from a high water problem due to high water levels in the river and flooding caused by flooding, especially around the monsoon. I am also involved in a port project in Bangladesh and inland development in Myanmar. “

CDR partner in PIB program Vietnam for Inland Waterways and Ports

By | All, Asia, Uncategorized

Minister Kaag of Foreign Trade & Development opened the 100th PIB program (Partners for International Business).
The 100th PIB program revolves around domestic waterways in Vietnam. Dutch companies excel in the dredging of waterways and in the development of ports. Vietnam can use this knowledge and expertise well.
To meet Vietnamese demand, Dutch companies have united in a PIB program. In addition, a government-to-government program is being set up under the direction of Rijkswaterstaat (Ministry of Infrastructure and Water Management). This must result in an integral policy approach for the waterway corridor at Ho Chi Minh City.
This ‘Dutch approach’ must then also be implemented in other parts of the country.

CDR International welcomes Mr. Thieu Stevens

By | All, Europe, Uncategorized

At the 1st of October 2018, Thieu Stevens (MSc.) joined the team of engineering experts of CDR International. After obtaining his Bachelor’s degree in Civil Engineering at the Avans University of Applied Sciences in Den Bosch, Thieu obtained his Master’s degree in Hydraulic Engineering at the Delft University of Technology. During his education, Thieu paid special attention to the design of (hydraulic) structures. He made the preliminary and detailed design for a small tunnel underneath the railway system near Assen, to obtain the Bachelor’s degree in Civil Engineering.
Thieu obtained his Master’s degree by developing a formula to predict the stability of stones in a bed protection based on the output of a Detached Eddy Simulation; including the effects of turbulence was the main challenge of his thesis, which was conducted at Deltares. In between, Thieu already gained some international experience during a multidisciplinary project about coastal protection by mangroves in the Mekong Delta of Vietnam.
CDR wishes Thieu all the best at the start of his career.

CDR International welcomes Mr. Attman Kar

By | All, Europe, Uncategorized

As of the 13th of August 2018, Mr. Attman Kar (M.Sc.) has strengthened the engineering team of CDR International as a Coastal and Marine Engineer.
Attman has graduated from the Delft University of Technology (TU Delft), the Netherlands, in 2017, after completing a Master’s degree in Civil Engineering, as part of the Erasmus+ Coastal and Marine Engineering and Management (CoMEM) programme. During the programme, he undertook parts of his studies as well as various projects at the Norwegian University of Science and Technology (NTNU), Norway, and the University of Southampton, the United Kingdom, apart from TU Delft.
During his graduate research at TU Delft, he tested the validity of two TU Delft-developed numerical models for shallow foreshores found in the low-latitude regions of the world, by comparing numerically obtained data with laboratory-obtained data, after replicating a similar foreshore in the laboratory.
Attman has wide international and engineering interests which he has shown during his education. For instance, he spent two months at the University Centre in Svalbard (UNIS) and studied climate change and its impact on coastal erosion, and the development of infrastructure in the fragile Arctic region. He also took part in a multidisciplinary project in the Netherlands and explored the feasibility of connecting the town of Holwerd to the Wadden Sea.
CDR wishes Attman all the best at the start of his career.
