About Us

SILT was originally formed as SILT Consultants in the year 1979 and is the first Nepalese privately registered firm specialized in geo-technical investigation and materials testing. SILT was converted into the private limited company in the year 1981. The establishment of the company took place during the time when consulting business had just started in the country. SILT, therefore, takes pride to be one of the pioneering firms in the development of Consulting Industry in Nepal.

Gradually, the increase in the scope of consulting services in various development sectors lead to the realization of multidisciplinary approach and thus SILT began with the diversification of consulting services into various fields of engineering, agriculture, rural development, environmental studies, social and economic studies, community development/gender studies, institutional and human resources development, as well as research and policy formulation related services.

SILT has its head office in Ratopul, Kathmandu and different project offices in Kathmandu and different parts of the country. SILT is well organized to provide the highest possible standards of technical and managerial services to its clients with a strong professional backing-up by a Board of eight Directors consisting of experts and specialists of different disciplines. SILT maintains good strength of in-house full time professional staffs and vast pool of resource professionals to ensure high quality services to its valued clients.

SILT provides services to its clients both independently and also in collaboration with other consulting firms of Nepal and abroad and has thus attained a level of performance commensurate with international standards.
