(1) Explain your problem, don't simply post "This isn't working". What were you doing when you faced the problem? What have you tried to resolve - did you look for a solution using "Search" ? Has it happened just once or several times?
(2) It's also good to get feedback when a solution is found, return to the original post to explain how it was resolved so that more people can also use the results.
Hi There,
Does anyone have handy examples of methods to demonstrate Disruption. Such as the Measured Mile.
Kind Regards

Hi Toby
In the real world as seen by the Main Contractor disruption occurs at the lower levels of the money feed chain.
In fact it starts right at the bottom with the guy on the stepladder trying to fix something - the person that Tony Bingham calls the "putterupperer".
If something disturbs his productive rhythm then he has been disrupted.
There is no system or formula that I know of that can calculate and quantify the value of that disruption to any degree of accuracy.
Especialy if the the sub-contractor that employs the "putterupperer" has no idea that he has been disrupted and has not made an upstream claim for the cost.
If the Main Contractor has not incurred any disruption costs from the subbies then there is no basis for a disruption claim to the Employer.

Toby,
If that paper is on offer, I wouldn't mind having a flick through.

Dear Stephen
The construction industry has developed and employed a number of methodologies for estimating lost labour productivity. Based on the appropriate data input, these methods can be classified into three major groups; namely:
(1) Project practice based;
(2) Industry based; and
(3) Cost based methods.
The detailed data requirements and corresponding judicial acceptance generally increase as the approach adopted moves from cost based to project practice based methods.
The below figure outlines the relationships between the availability, quality and providence of the
contemporaneous project documentation, the reliability of the methods of quantifying lost productivity
and the cost and expertise generally required to record, prepare, and document the quantum of
damages derived thereby.
I have a very good paper written by a colleague of mine which i can let you have if you wish.
Hi Stephen
The measured mile system sets out to demonstrate that productivity achieved in ideal conditions is better than that in disrupted conditions.
The theory says that the difference in productivity is caused by events outside the contractor's control and therefore should be compensated.
The problem is that the work done in the measured mile section is never identical to that done in the disrupted section and it is difficult to filter out the disruption caused by events.
For instance if the measured mile was on level three of the building and the disruption occurred on level 7 then productivity would naturally be less on 7 without any disruptive events
The time of year also has an effect.
In truth it is very difficult to calculate loss of productivity in a disruption claim.
To start with you have to have very detailed time sheets and preferably your own employed workforce before you start.
