Update of the Topographic Parameters of the Structural Elements to the Pipes Networks

He paper presents a way of updating the parameters of representation and tracing of the structural elements to the water supply networks in the execution or rehabilitation phase. Between the design phase and the construction phase of the pipe network components there are divergences in the field tracing. This situation arises, in particular, in the execution of rehabilitation works for water supply pipes. The case study on the rehabilitation works of the Timisesti - Iasi adduction pipeline that underlines the river Moldova confirms the necessity of changes in time of the topographic documentation of the execution. The morphological changes of the Moldova River bed during the period between the implementation of the rehabilitation project and its application in practice necessitated the modification of the situation plan and of the longitudinal profiles. The updating of the topographical documentation was carried out during the start of the execution of the works (plans for the location of the constructions and installations) and then during the rehabilitation works (longitudinal and transversal profiles).
