EOTs Concurrency review

Hi Ellie

There are two types of concurrency:

1. Concurrent Cause - where two or more delay events occur in the same time zone and each have a delay impact.

2. Concurrent Effect - where two or more delay events occur in different time zones but each have a delay impact.

It seems that your case is Concurrent Effect.

The same rules of allocation of EoT - LAD's & Prologation costs apply in each case.

Hi Aqil

Concurrency is when delay events impact within the same time frame - more or less.

There is no concurrency for a delay at the beginning and another at the end of a project.

Remember concurrency is only an issue if money is involved.

How do u define/see the same time frame in your following  statement

Concurrency is whewhen delay events impact within the same time frame 

as stated by yourself in your previous response as well as supported by SCL  the Concurrent Effect is  where two or more delay events occur in different time zones but each have a delay impact.

from above it is deduced that Employer and Contractor's risk events can occur at any time to produce concurrent effect.

Please clarify.

Hi Aqil

You are correct if you are talking about delay effect rather than delay cause.

Hi

how we get the concurrent effect while using the time impact analysis ,

We have the updated programmes each month 

suppose Employer delay apear in Jun, 16 - we have the updated programme and we can record the total delays 

We can make the fragnent of delay and can have the impact due to delay of employer , 

But this info give us  the contractor delay before event and employer delay after event 

If we do so for all delays we will get the same delays contractor delays and employers delay- what about concurrency
