Construction and complexity go hand in hand...  

That’s inevitable any time you mix together large budgets, long schedules, complicated designs, lots of contractors, and an assortment of competing interests. Murphy’s Law can take root any number of places if you don’t have a keen oversight of your entire project.

For more than five years GHA has been managing information for some of Washington State’s most ambitious construction and engineering projects. From planning to completion, we manage people, process, and technology and deliver the transparency you need to achieve on-time, on-budget results.
