4.Which study for which project?

The topographic study: every project's foundation

Topography is the first study performed on any land. It produces a precise plan of the plot with dimensions, altitudes, boundaries and existing features. Without a topographic survey, no building, subdivision or development project can be planned correctly.

Indispensable for: every land project without exception
Produces: topographic plan, contour lines, area calculation
Performed by: sworn expert surveyor
Timeline: 1 to 3 weeks depending on area

The geotechnical study: understanding soil

Geotechnical studies analyse soil mechanical properties to determine bearing capacity, composition and suitable foundations. They are indispensable before any building to avoid settlement, instability or collapse problems.

Indispensable for: buildings, subdivisions, infrastructure projects
Produces: geotechnical report with foundation recommendations
Performed by: geotechnical engineering firm
Timeline: 2 to 6 weeks depending on complexity

The hydrological study: mastering water

Hydrological studies analyse a site's surface and groundwater. They are essential for designing drainage, assessing flood risk and sizing hydraulic structures.

Indispensable for: low-lying land, servicing projects, subdivisions
Produces: hydrological report, drainage plan, structure sizing
Performed by: hydraulic engineer
Timeline: 2 to 4 weeks

Which study for which project?

General rule: topography is always needed. Geotechnics is indispensable as soon as there is building. Hydrology is required for any servicing project or at-risk land.

Frequently asked questions

Can several studies run at the same time?

Yes, and it is even recommended to save time. VISION-H coordinates all field studies to optimise timelines and result consistency.
