(1) As per RDSO Drg No. T-2496, the weight of PSC Sleepers ordinary 60 kg is 281.47 Kg.
(2)As per track manual the weight of slepper is 282Kg (Excluding the weight of fastenings which consist of inserts, liners, pandrol clips), the the weight of PSC Ord. 60 kg along with insert comes to 282+6.1=288.1Kg.
(3) As per the IPWE booklet the weight is 286.5Kg.
(4) The actual weight of PSC ord. 60Kg sleeper differs from factory to factory.

Due to above differences I am facing facing difficulty in recording the weight of the sleeper. Please guide what is the theoretical weight of PSC Ord. 60 kg Drg No. T-2496 and the reference.
Thanks.

AS per the specific gravity of ingradients the weight of sleepers differ from factory to factory, and in the same factory if the aggregates quarry changesor even from the same quarry at different depth the specific gravity of aggregates differs, you must ensure by actual wighing in a weighing machine. To adopt uniformity adopt the approxinate weight given in the RDSO drawing. RDSO drawing give plus or minus 3mm in the overall length of the sleeper, this also made sleeper weight differ from one to another.

Sleepers are to be sample weighed & the average weight to be considered.

The actual weigh of sleepers may find out by averaging truck's weighment in different days. for payment purpose, the actual weight or theoretical weight whichever less shall be considered.
To avoid such type of situation a clear condition may also be incorporated in tender at the time of preparation of tender.

In the tender itself instead of mentioning weight basis for track sleepers it should be mentioned as numbers and other type of sleepers such as points and crossing as set to be mentioned in the tender itself in order to avoid dispute at a later stage.

PSC Line sleepers are taken in Nos.and PSC turn out sleepers , SEJ sleepers, Bridge approach sleeprs are taken in sets. The level crossing sleepers and the deck bridge sleepers are taken in Nos. Thus there is no question of dispute in payment of sleepers. However we may consider the RDSO's weight for other purposes if required.
