Question 13

What is the FS dependency? Give two examples

Answer 13

Finish to Start
B cannot start until A is finished
e.g. formwork must be completed before pouring concrete
e.g. land must be purchased before building can start

Question 14

What is the FF dependency? Give two examples

Answer 14

Finish to Finish
B cannot finish before A is finished
e.g. rebar must be completed before inspection can be finished
e.g. laying asphalt must be complete before line painting can be completed

Question 15

What is the SS dependency? Give two examples

Answer 15

Start to Start
B cannot before A is started
e.g. pour slab and cure slab
e.g. road excavating must start before asphalt can start to be laid

Question 16

What is the SF dependency? Give two examples

Answer 16

Start to Finish
B cannot finish before A is started
e.g. road excavating must start before line painting can be finished
e.g. turn on machinery and turn off machinery
