About Walid

With solid experience gained within industry leaders (Geofit, Socotec), I support stakeholders in construction, industry, and local authorities in the success of their topographic and geospatial projects.

Expert in topography, 3D digitization, and monitoring, I offer flexible technical support to surveying firms, engineering offices, and civil engineering and structural inspection companies in the success of their technical projects.

I provide flexible reinforcement and precision expertise, allowing me to meet your needs without the constraints of traditional recruitment.

My areas of intervention:

🔭 Topography:
– Surveys & setting out on all types of sites.
– Precision frameworks: high-precision polygonation and leveling.
– GNSS proficiency: RTK & Post-processing.

📉 Precision Monitoring & Surveillance:
– Design of protocols and instrumentation monitoring.
– Precision calculations using the least squares method (Ltop).
– Control and validation of measurements for optimal reliability.
– Dedicated Data Manager for piloting your monitoring systems.

🧊 3D Data:
– Acquisition and processing of 3D Scan and Drone data (Photogrammetry & LiDAR).
– DTM modeling.
– Scan-to-BIM.

📐 Engineering & Expertise:
– Data processing and calculations.
– Operational management of your topographic and monitoring projects.
– Technical writing: technical memorandums and execution procedures.

I am perfectly aware of the precision requirements and often tight deadlines of our profession. I am immediately available to absorb surplus production during periods of high workload.

I would be delighted to connect for a video call to discuss how I can strengthen your teams, both on your current projects and to anticipate your future peak loads.
