ABSTRACT

As stated in Chapter 4, it is the designer’s responsibility to design the instrumentation system for the dam. But it is equally essential that the designer gives the purpose of instrumentation, the specifications of each of the instruments, the parameters to be monitored, with locations, and the frequency of data collection. This requires explicit prediction of behaviour of the dam with solutions in case of abnormal incidences. Specifications of instruments will help to procure instruments, but the ways and means to procure, select, and install, are the most important aspects of instrumentation. The installation report, comprising location of instruments, as actually installed, purpose, operation and maintenance of each instrument and the frequencies with which the data have to be collected, a well planned sequence of activities, guarantee the achievement of the objectives of instrumentation. This also implies selection and training of personnel involved and their continuity in a job, particularly after the construction activity is over, with reduced supervisory staff and the additional responsibility of transmission of data, to the authorities concerned, with minimum delay.
