The premise of the question is - Building completion has to be preceded by the landscaping and land scaping should start atleast 15 days before building completion. Exact Question is -
Which of the following relationships most likely represents the relationship of the start of landscaping work to the completion of the office building?
A. FS with 15 days Lead
B. SF with 15 days Lead
C FS with 15 days Lag
D. SF with 15 days Lag
Though this is a simple question but i am baffled by the answer a bit
Can you please explain and also why
Based on the description you gave "Building completion has to be PRECEDED by the landscaping" I would have selected answer "A. FS with 15 days Lead" because FS with a lead makes the second task start earlier.
Have you contacted the original question author and asked for an explanation?

Question on Lead and Lag
5 months 2 weeks ago #11442
Suppose the Building Construction work need 40 days. and Land Scaping need 30 days.
In normal process, The building will be completed first within 40 days and then Land Scaping will take 30 days.Total Time will be 40+30=70 days.
But Applying Lead time for Land Scaping...The task will start 15, Total workdays prior and thereby overlap the construction work for 15 days. So, total time will be
40+15(30-15)=55 days. So it is Finish to start 15. That means Building completion task finishes and prior to finish that task Land Scaping start..
