The purpose of the Methodology is to familiarize all target groups that are involved in the implementation of works on
railway overhead with the possibility of using DGS as a control mechanism to ensure their quality, and not only in relation to the prescribed tests.

Potential users:

  • the contractor's workers, - for the appropriate, wider use of these DGS 90N to achieve the required quality and therefore the durability of the structure and also to increase the efficiency of the actual execution,
  • employees of testing organizations - for the correct execution of repair work, (and beyond the requirement of the result, possibly also the interpretation of the results during the execution),
  • professional technical supervision staff, representative of the client/construction manager, or supervisory organization - for assessment of the desired result, including in wider contexts.
