Material saved is Money earned .

Overview:

At a construction site, different types of materials are procured and used . Some items are quite small in size but costly. Most  of the pilferage and wastage can be controlled with a vigilant eye around the site and proper working methods.
It is essential that the Supervisor of the site  keeps a proper track of the material so that pilferage , wastage & damage is avoided.
A culture of accountability needs to be instilled at site so that proper care can be taken for each and every material ; small or large.

 This article explains what are the different ways in which material can get lost & damaged and provides tips so that these can be preserved properly.

This article explains what are the different ways in which A class material can get lost & damaged and also gives tips so that these can be preserved properly.

1.Cement:
Cement gets wasted during unloading , storage , handling, mixing of concrete , mixing of mortar etc.

2.Cement stores:
Often old cement bags get set in the godown. New bags are received and deposited above old stock. Naturally new bags are first used leaving old bags to be left again.
Invariably these bags become solid and have to be later dumped in the back filling along with boulders.
(tip: Use FIFO : First in first out )

3.Cement issued from stores:
Cement issued for masonry or plastering gets dumped at the location of work but the remaining bags are not returned to godown in the evening. Next day these bags get a fresh shower during the curing process and get set.

TipIssue cement bags to the sub contractor and debit the cost to him in case of such waste)

4.Cement pilfered to Labor hutments:
A random quantity of cement also gets pilfered to hutments for unauthorized pavings , platforms.

(Note: This is often unavoidable because of sensitivity . This can be tackled by involving the labor gang  )

5.Sand  & Aggregates are unloaded on the natural soil .The lower crust cannot be used due to presence of soil and has to be dumped in the back filling for footings or in the plinth filling

TipMake a bricks on edge platform without using mortar and unload material on thisMake bunds with bricks around the  storage)

6.Cement mortar :
Sand is placed directly on floor ,cement bag is added and a water pipe is kept over it till it floods the mix. Cement slurry overflows on the slab and is wasted.

TipUse mild steel trays for mixing mortars . You shall have to insist on the use.)

7.Concrete:

First batch mixed is dumped near mixer for making the seat for the hopper and is obviously wasted.

TipUse of old mild steel plates for the platform where trolleys can be parked while receiving concrete from the drum)

LOOK AT THE SET CEMENT BAGS  AT THE BASE OF THE MIXER.[ THESE BECAME SOLID IN THE CEMENT STORES ]

8.Surplus concrete when mixed at site :
Often during mass concrete , a certain quantity from the last batch gets surplus and is dumped on the site .
TipPrepare part batch during end of concrete)

9.Surplus concrete when ordered through RMC plant  :
Certain quantity from  the last transit mixer becomes surplus and cannot be utilized.
Tip: Keep more area ready for concreting such as columns or footings and order part transit mixer in the finishing phase.)
ORDERING RMC  HAS TO BE DONE WISELY

10.Reinforcement bars:

Fitters dump the  cut pieces bar on site . These get covered by soil and are lost.

( Tip: Issue steel  to the RCC sub contractor and debit the cost to him in case of such waste)

LOOK AT THE WAY THE BARS HAVE BEEN TIED UP WITH CHAIN & LOCK FOR SECURITY.

11.Binding wire :
The surplus cut pieces of binding wire are dumped on the centering which just get buried in the concrete.

( Tip: Issue binding wire in bunch of pre-cut pieces  to the RCC sub contractor and debit the cost to him in case of such waste)
12.Plumbing fixtures & Sanitary fittings: These are costly fittings and hence as a general rule always provided in the toilet after the door shutters have been fixed. keep the toilets under lock & key.
Aluminum sections: Get stained due to cement plaster spots. So as rule, these are fixed only after the plastering is completed and properly cured

Wooden sections: Get warped in presence of water . Normally stored in the covered area where plinth has been completed.

Electrical conduits & fittings: To be stored in the godown and issued to the electrical sub contractor on day to day basis only.

Author’s note :
In some future post we shall discuss the preservation of form work material and also speak about taking care of the construction equipment.
