About Our Laboratory

GCI-Lab is an institute’s testing laboratory, mainly opened for ITC’s students for understanding the practical experiment test in the research fields and in the civil engineering fields. On the other hand, we are accepting some exterior testing to make close cooperation between ITC and private companies in developing quality materials use. GCI-Lab delivers superior value to all its customer by leveraging its expertise in material testing services, inspection, consulting, research and training.

The laboratory is government owned. Lab’s equipment was aided by CIUF (Coopération Universitaire Institutionnelle Universités Francophones de Belgique), CF (Coopération Française) and ministry of education and work. All equipments are approved in accordance with the relevant international and municipality standards and specifications.

GCI-Lab is empowered with young, skillful and experienced professional to deliver quality services through provision of precise, reliable and timely results. All tests are based on internationally accepted standards, procedures and specifications (ASTM, AASHTO, BS, EN, NF).

Our Purpose
