Letters issued to Soil Investigation Services by the clients themselves, on their own letterhead, after the work was finished and inspected. Published here in full so you can read them rather than take our word for it.
Anyone can list impressive client names on a website. A completion certificate is different: it is written by the client, it names the project, it states what was done, and somebody senior put their signature to it.
The certificates below cover geotechnical investigation for a hospital in Gwadar, a petrochemical expansion at Port Qasim, bridge foundations in Mirpurkhas and building work across Karachi. Between them they span 2018 to 2021 and cover standard penetration testing, cone penetration testing, borehole drilling, sampling, laboratory testing and report writing.
They are reproduced exactly as issued. Nothing has been cropped out, retouched or edited.
Further references are available on request, including projects where the client has asked us not to publish.

Soil investigation completed in the given time and scope: standard penetration and cone penetration testing at required formation, laboratory testing of soil and rock samples, and comprehensive report writing.
Different clients, different provinces, the same sequence of work.
Every one of these projects began with boreholes advanced to design depth and logged as they were drilled.
Penetration testing at set intervals gave the in situ strength profile that the foundation design was built on.
Soil and rock samples were classified and tested for strength and compressibility under controlled laboratory conditions.
Each closed with a signed report stating bearing capacity, settlement and a clear foundation recommendation.
