Fundamental Integrated Site Appraisal Services Limited (FISAS) is a 100% Nigerian geo-data collection company that offers Integrated Site Assessments services to reduce engineering, geological and environmental complexities and risks associated with infrastructure development programmes in all sectors of the economy.

The paucity of environmental, geological, and engineering data in Nigeria’s infrastructure risk management is from poor early work planning. Consequently, using the One Oasis model, FISAS has assembled an experienced, inventive, and innovative multidisciplinary team of experts to collect, analyse and interpret these data to reduce infrastructure development complexities and risks.
