tracing) duly signed by them and Railway Divisional officials after immediate completion of the work in accordance with para 911 of Indian
Railway Works Manual.
4. Load test has to be carried out in presence of NHAI & Railway Authorities immediately after completion of the superstructure considering the
provisions of IRC SP 51-2015 - Guide lines for load testing of Bridges.
5. All the records of Quality Assurance / Quality Control, testing of the materials and satisfactory completion of an activity shall be maintained at
site by the Contractor's Engineer and Supervising Engineers. On the basis of the records, Railways Engineers shall do stage wise clearance.
Without such stage clearance, the work in the next stage of construction shall be not allowed by the Railway Supervisor, unless proper system
of check and exercise is followed at the site.
