Planning and Scheduling with Building Access Date Constraints

Member for

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.
