Surrounded by lush pine forests, majestic views and unspoiled land that extends as far as the eye can see, it’s tough to imagine the city of Flagstaff, Arizona having a housing crisis. But the beauty of those natural surroundings has lured tourists who, enamored of the area, have been buying homes, driving up their cost.

Two of the most vexing challenges faced by today’s construction professional are the ability to ensure excellence in grading and dealing with ongoing design changes. While the advent of machine control helped alleviate some of the dependence upon grade stakes, blue tops, and the like, increasingly tightening specs remain a concern. And, while the use of removeable storage like thumb drives has helped facilitate the transfer of design data, making that happen can still be still a time-consuming practice.
