"This year we have the benefit of the soon-to-be president of the United States telling us what to plan for, given his stated plans to focus on the nation's infrastructure.

"The particularly relevant sectors include transportation, general building, and utilities. The company services government entities as well as private and institutional clients.

"Project management firm Hill International (NYSE: HIL) is one of the best ways to profit from the public works projects planned in government stimulus packages," says Dave Dyer.

In his The Dave Dyer Newsletter, he explains, "HIL is a consulting company that provides expertise in the project management area. Their business is a people business, not a business that requires them to invest in a lot of heavy construction equipment.

"I think this gives them three advantages: first, they do not have the long marketing cycle that can last for years on a large project, second, they have greater flexibility to expand or contract as business opportunities change, and third, their fee-based revenue structure is less risky than other compensation models used in the construction industry.

"HIL has two divisions. Its original business, founded in 1976, was a construction litigation support company that supplied expert witnesses and other expertise to construction companies involved in contract disputes.

"They saw early in their history that they could also provide value as a dispute preventer rather than just an after the fact resolver, so they started a project management division.
