Question 1 for sbl 2018 sep

For Sep 2018,
I have some question on answer for Q1(a) :
Under financial heading, 4th paragragh:
“the project will tie up considerable working capital over its lifetime”
Why it say so?

Under non-financial heading, 1st paragraph:
“the government believe that it will be possible to construct a road which is not significantly affected by problems with the terrain…”
But I couldn’t find it in the case. Is this assumption that we make?

Thank you.
