PTI provides design experience and works out calculations with regard to structural, water design, earthwork, basic roadwork, providing civil design services including preparation of civil/site work drawings, structural evaluation and designs, and water/sewer designs based on exiting local utilities and facility load. PTI coordinates and reviews surveys to prepare easements and to establish control of line and grade in the construction of water lines and sanitary sewers. We also review and approve hydraulic calculation for extension of water and sewer lines and sewer line cut sheets.

Our engineers assist in the development of hydraulic commuter models of the water distribution system. In Afghanistan, we supervise and collect field data for calibration and verification of various models.
