American construction firms?

Question

What are the names of some of the large construction firms that operate throughout America?

eg. the sort of companies I am referring to are like Carillion, Kier, Balfour Beatty, Laing O'Rourke, Mace etc.

[These are familiar companies to me that operate in the UK, whether they operate in America is beyond my knowledge]

Answer 1

Depending on the general type of construction these may be appropriate:

Fluor Daniel

Bechtel

Kellogg Brown & Root (KBR)

Mortenson

Stone & Webster

Sargent Lundy

Zachry Engineering & Construction

Answer 2

I think that some of the ones you mentioned are based either in the U.S. or Canada.
