Civil | GRAHAM CONSTRUCTION AND ENGINEERING – WASTEWATER TREATMENT PLANT UPGRADE Steady Flow A t Graham Construction and Engineering, the company’s vision is to be North America’s premier integrated construction solutions partner, Senior Project Manager Troy Gaudet explains.

This means that the construction of the BAF facility will be expedited so that it is ready for startup in the early fall of 2013, rather than during the winter of 2014.
