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,

I am trying to figure out what will be the best way to show plan when I have constraints on accessing the building to perform installation of items.

For example, I need to access the dates between 1 Dec and 31 Dec, but my parts won't arrive until 15 January.  How could I show the 15 January in a Critical Path, that it is affected by the building access dates.

I can post a sample of the activities if someone is willing to help me further.

Regards,

you have several options 

from your senerio it appears that you have 15 calendar days of float between Dec 31 and Jan 15 so this is a little confusing to me. The building access is NOT delaying the project but the parts delivery is the driving factor.

but to do what you want 

option #1 use 2 constraints and a lag

for the acess activity use a primary constraint start on or after 1 Dec and a secondary constraint fnish on or before Dec 31

now for the parts delivery you can use a expect finish date constraint of Jan 15 and put a 10 day lag from the building access activity to the parts delivery. 

option #2 use 2 constraints and add a 10 day activity for packing/loading/transportation

for the acess activity use a primary constraint start on or after 1 Dec and a secondary constraint fnish on or before Dec 31

add a 10 day activity for packing/loading/transportation AFTER the access and prior to the installation.
