Why Does a Soil Report Stand Between You and the Permit?
Before the municipality lets you build, it wants scientific proof that the land can support what you intend. That proof is the soil report: an engineering document signed by a licensed laboratory that describes the site's layers and their capacity to carry your structure — mandated explicitly by Saudi Building Code SBC 303.
What Baladi Accepts
For your file to pass on the first submission, the uploaded report must be:
- Issued by an engineering laboratory licensed with the competent authorities
- Signed by a certified geotechnical engineer
- Built on real, documented borings and field tests — not paperwork
- Compliant with the soil and foundations provisions of SBC 303
Anatomy of an Acceptable Report: Three Parts
First: the fieldwork
- Borings at depths matched to the structure
- SPT tests through the layer sequence
- Undisturbed samples for the laboratory
- Groundwater level records
Second: the laboratory
- Soil classification per USCS / AASHTO
- Moisture content and dry density
- Atterberg limits on clayey layers
- Chemical analysis of salts and sulfates — essential near coastlines
Third: the recommendations
- The most suitable foundation system: isolated footings, raft, or piles
- Allowable bearing capacity, in numbers
- Recommended founding depth
- Protection measures where the soil is chemically aggressive
How Many Borings Does Your Project Need?
| Project | Borings | Depth |
|---|---|---|
| Residential villa | 2 – 3 | 10 – 15 m |
| Residential building (3–6 floors) | 3 – 4 | 15 – 20 m |
| Commercial / tower | 4 – 8 | 20 – 40 m |
| Industrial / roads | Site-dependent | 5 – 15 m |
The Ghost Report: a Shortcut into a Long Problem
Someone may offer you a "ready-made report" with no actual borings. Remember what that report does:
- ❌ Fails Baladi and supervisory audits
- ❌ Voids latent-defect insurance coverage
- ❌ Puts full liability on the contractor and engineering office
- ❌ Cancels any structural warranty on the building
Always verify the lab's license, and ask for field execution photos and instrument records before accepting any report.

Bottom Line
The soil report is not routine paperwork — it is the gateway to your permit and the legal and engineering safety valve of your project. Start it early, and pick a licensed laboratory whose reports pass on the first submission.
