The Cost of Rework and How to Prevent It
The cost of rework? I always give a simple example of this that even non-construction people can understand.
Fit a window and, later, discover that the style has been changed, perhaps from vertical to horizontally opening panes. Now let’s assume that the window frame had been ordered and fitted before the change was decided upon. That means no cost to the contractor for swapping it over– that would just be passed on to the client.Now the window has just been fitted but has to be replaced. All that is involved is removing 4 screws, removing the unit, placing the new unit and fitting 4 screws. A quarter of an hour’s work?
The other extreme is that nobody noticed the change that quickly – the revised drawing simply didn’t arrive on site quickly; getting copies made to hand over to the subbies took more time. The window frame has been fitted and glazed. Externally it has had silicon sealant applied round the joints to the masonry. Internally the wall has been plastered up to the window frame and it has been decorated. To replace that window frame will require the input of at least four skilled trades and take days to sort out! In extreme cases it could even be the cause of Delay and clock up LAD for a week!!! So I’ll let you work out the cost of that rework yourselves! Trouble is that the date it was changed is shown on the revised drawing! To argue the case would cost a bomb for a Forensic Delay Analysis!
So how do we avoid this kind of rework? Easy; we make sure that everyone involved in the project has a copy of the revised drawings the instant they are issued! Any mistakes requiring rework then, and the finger points and the bill gets sent! So how do we make sure everyone instantly gets revised drawings? Well the answer to that is dead easy! :-

However rework may also be necessary due to another cause; defective workmanship! This, too, can be a very costly exercise and can also be the cause of Delay and LAD. The cost of this rework is best kept down by the site management spending part of their every day wandering around the site with their eyes wide open! See a defect and tell the lads to get it sorted p.d.q.! This is pretty effective because the lads, being a bit proud of themselves, don’t like having their work criticised. Doing this comes under the label of “De-snag as you go.” The spin-off is that the lads even go as far as doing any necessary rework before it is even seen by the site management!
But the poor old site manager! How does he find the time to wander round the site with his eyes wide open when so much of his time has to be spent in his office dealing with the project’s ridiculous amount of paperwork? Again, a dead simple answer: do away with the paperwork:-

Now when giving these two examples of what “rework” can mean I have used two frightening, dreadful expressions: “Delay” and “LAD”! These two can see a contractor stuck with such a huge bill that the only way out is bankruptcy! So how do you steer clear of having these expressions thrown at your company? For the third time today – an easy answer!
