CAD laboratory is equipped with a computer network with necessary hardware and civil engineering software specializing in structural analysis, drafting and developing solutions for industrial applications. Some of the commercial finite element packages available at CAD Lab are SAP2000, MIDAS, GRASP and FLAC. In addition to that, some in-house codes are also available for various structural analysis and design purposes. Furthermore, CAD laboratory provides working environment for undergraduate and post-graduate research studies
