Challenges

With the earlier blocks (wherein Blue Star was associated) in full operating mode, the main challenge with respect to HVAC works was the lifting of chillers to a height of 60 m. Keeping in mind the challenging working environment,a special emphasis on safety practices and modern construction tools and tackles, ensured safe lifting operation of chillers.

Under the electrical scope, an impediment was the erection of a 2500A outdoor type sandwich bus duct and running of DG cables from an existing building to the new building over functioning transformers and DG (triple height area). Another challenge was the laying of LT cables over the operational DGs wherein welding activities were performed above a fuel tank. All the tasks were executed under expert supervision and necessary safety precautions were practised with no compromises.
