The condemning of old and unserviceable Machinery & equipment must be of the following
A)
The Machineries must be over the life span fixed by condemnation board of Mizoram Govt.
B)
The Machineries must be off-road
C)
The Machineries must be beyond economical repair
D)
All of the above
In the context of Asset Management and Government Financial Rules (GFR) applicable to departments like the PWD in Mizoram, 'condemnation' is the formal process of declaring an asset unfit for further use. For machinery and equipment to be condemned, they typically must meet several criteria to ensure public funds are not wasted:
1. Life Span (Option a): Assets are generally evaluated based on the prescribed 'economic life' or 'useful life' fixed by the government or a designated condemnation board. If an asset has exceeded this period, it is a primary candidate for condemnation.
2. Operational Status (Option b): If machinery is 'off-road' (non-functional) and cannot be brought back into service, it is considered unserviceable.
3. Economic Viability (Option c): The most critical technical criterion is whether the asset is 'beyond economical repair' (BER). This means the cost of repairing the equipment would be too high relative to its current value or the cost of a new replacement.
Since all three conditions (age/life span, operational failure, and lack of economic viability for repair) are standard grounds for the condemnation of government machinery, option 'd' is the correct choice.
