Carrying out detailed physical investigation of Dimbhe dam (Masonry dam) with Electrical Resistivity Imaging Method to find the seepage path, cavities and water saturation areas in the masonry of dam body including cost of all materials. Machinery, equipment’s, labour, insurance charges, transportation with all leads and lifts and any other incidental charges etc. making of reports in soft copies and hard copies. The results should provide pictures of internal resistivity distribution of the dam structure, identifying areas of water saturation in the dam body, and thus identifying the zones of water accumulation and wetting etc. complete

Carrying out detailed physical investigation of Dimbhe dam (Masonry dam) with Streaming potential method to infer seepage patterns and concentrated seepage flows and to identify the zones in the dam body through which seepage is taking place. The results are correlated with resistivity sections. including cost of all materials. Machinery, equipment’s, labour, insurance charges, transportation with all leads and lifts and any other incidental charges etc. making of reports in soft copies and hard copies etc. complete.

Carrying out detailed physical investigation of NOF section Dimbhe dam (Masonry dam) with Multichannel Analysis of Surface Waves (MASW) method is one of the seismic survey methods evaluating the elastic condition (stiffness) of the ground., this method measure seismic surface waves generated from various types of seismic chasssledge hammer analyses the propagation velocities of those surface waves, and then finally reduces shear-wave velocity (Vs) variations below the surveyed area that is most responsible for the analysed propagation velocity pattern of surface waves including cost of all materials. Machinery, equipment’s, labour, insurance charges, transportation with all leads and lifts and any other incidental charges etc. making of reports in soft copies and hard copies etc. complete.

Carrying out detailed physical investigation of Over Flow section Dimbhe dam (Masonry dam) with Cross face Tomography method. Seismic Tomography is conducted in two configurations. In first configuration, tomography (L-section tomography) is conducted between dam top/spillway crest and galleries. In second configuration, tomography (cross face tomography) is conducted between two faces of the Dam. Tomography provides high resolution details of internal structure. including cost of all materials. Machinery, equipment’s, labour, insurance charges, transportation with all leads and lifts and any other incidental charges etc. making of reports in soft copies and hard copies etc. complete

Carrying out detailed physical investigation of Non Over Flow section Dimbhe dam (Masonry dam) with Cross face Tomography method. Seismic Tomography is conducted in two configurations. In first configuration, tomography (L-section tomography) is conducted between dam top/spillway crest, Inspection/Foundation galleries. In second configuration, tomography (cross face tomography) is conducted between two faces of the Dam. Tomography provides high resolution details of internal structure. Including cost of all materials.
