Tips on using this forum..

(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

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

 

Regards

Bilal

Hi Aqil

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

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

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.

Mike If empkoyer risk event (ERE) occuring at early stage for say 100days and contractor risk event (CRE) occuring at a very late stage for say 120 days, and both ERE and CRE are critical delays to completion on parallel critical paths, would they produce a concurrent effect of 100 days? Please clarify Regards

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.
