On April 24, 2026, at its Hanoi office, A2Z Construction Consulting Joint Stock Company held a working session with Jiangsu Delauney Information Technology Co., Ltd. and Wuhan Tensense Geotech Co., Ltd. (China) to exchange solutions for digitalizing geotechnical investigation.
The program was organized at the request of the two Chinese partners. During the session, participants discussed the current state of geotechnical investigation in Vietnam, along with emerging trends in the application of digital technologies for data acquisition, management and utilization. These efforts aim to enhance the reliability of geotechnical data serving engineering design.
Overview of the working session.
Advancing the digitalization of geotechnical survey data
Assessing the current situation, Mr. Mai Manh Hong, Chairman of A2Z Construction Consulting Joint Stock Company, emphasized that geotechnical investigation remains one of the bottlenecks in the implementation of transport infrastructure projects in Vietnam. Data collection is still fragmented and lacks consistency; procedures and templates have yet to be standardized; and data compilation and storage largely rely on manual methods, posing risks of errors and making quality control more challenging.
According to Mr. Hong, when multiple projects are carried out simultaneously across different locations, the management and utilization of survey data become increasingly complex. Information such as borehole locations, spacing between survey points, geological conditions, weather at the time of investigation, and sampling procedures often depend on field reports and engineers’ assessments. This approach limits the ability to verify and cross-check data effectively.
From this perspective, the adoption of digital technologies in geotechnical investigation is considered a necessary direction to establish a unified data system, enhance control capabilities and shorten processing time.
According to Mr. Mai Manh Hong, Chairman of A2Z Construction Consulting Joint Stock Company, digitalization is a necessary solution to address fragmented and inconsistent data, while enhancing control in geotechnical investigation activities.
During the working session, Mr. Truong Dat Pham, Market director of Jiangsu Delauney Information Technology Co., Ltd., introduced a survey data management platform designed to comprehensively capture field information and integrate it across project implementation stages. The system enables the standardization of templates and data entry processes, while synchronizing data to the central management system in real time.
On that basis, survey data is structured into a centralized database, supporting storage, retrieval, and utilization by project, survey location, or specific technical criteria.

Proactively controlling complex geological conditions from the survey stage
Regarding complex geological conditions, Mr. Mai Manh Hong noted that many areas in Vietnam feature karst terrain, with the presence of karst caves, weathered zones, and subsurface geological anomalies.
“If not fully identified during the survey stage, these factors can directly affect foundation design solutions and pose risks during construction”, he emphasized.
According to him, the application of geophysical measurement technologies combined with field data acquisition systems enables early detection of geological anomalies, thereby providing reliable data for design and ground treatment. This is a critical requirement to improve survey quality and risk control in transport infrastructure projects.
In line with this requirement, solutions for on-site data collection and processing were introduced as an appropriate approach. In this regard, Mr. Abby Hu, Engineer at Wuhan Tensense Geotech Co., Ltd., presented an integrated system of geological measurement and data acquisition equipment equipped with specialized sensors. The system is capable of recording parameters during drilling, including depth, operational status, drill inclination, and geological characteristics by layer.
These data are transmitted to the central system in real time via a connected network and can be integrated with images from monitoring cameras to provide a visual overview of drilling and sampling activities. All information is stored on a cloud-based platform for aggregation, analysis, and reporting as needed.
With its integrated design, the system allows multiple measurements to be conducted in a single drilling operation, reducing manual intervention and minimizing discrepancies compared to traditional recording methods. As a result, the “real-time data capture during drilling” process is continuously implemented, shortening data processing time while enhancing accuracy and responsiveness in decision-making.
All survey data are centrally stored and maintained throughout the project lifecycle, facilitating inspection and evaluation, while also supporting training and the accumulation of data for future projects.
A representative of Wuhan Tensense Geotech Co., Ltd. introduced the on-site geological measurement and data acquisition system.
Based on the discussions, Mr. Mai Manh Hong proposed that the parties consider piloting the survey data management platform and on-site measurement and data acquisition system in several key projects where A2Z is involved in survey and design, such as Dong Dang – Tra Linh and Huu Nghi – Chi Lang expressways. The pilot implementation aims to assess the suitability and effectiveness of the technologies and equipment under actual conditions in Vietnam.
The initial results will serve as a basis for further research and refinement of the solutions, as well as for evaluating potential cooperation in the future, grounded on their practical applicability and performance in the Vietnamese context.
