I am a large diameter driller of caissions and a shoring wall builder
always looking for projects in need of my specialty to bid on in the
western U.S..  McGraw-Hill / Dodge have nearly monopolised this
information at a heavy price.  I am looking for direction on
consistently finding projects out for bid that call for large diameter
/ drilled foundations. How do I find the names and businesses of
primary contacts (i.e. project estimators, chief esimators) in western
U.S. construction companies and owners of property / properties in
need of caission foundations, micro piles, soldier piles, shoring
walls or blasting with out paying large subscription fees?
