"Throughout the course of the project, Barclay's personnel conducted themselves professionally, despite the pressures of the job. Despite cash flow issues created by delays and so many changes, Barclay held their subcontractors in line, as each issue was resolved commercially in an amicable fashion. Barclay kept the job moving, despite some work being delayed into a particularly harsh winter period."

"Gerdau Cambridge has had the opportunity to use Barclay Construction Group on numerous occasions over the previous fifteen years.  Barclay consistently delivered exceptional results during demanding shutdown conditions.

Barclay has shown professionalism, dedication and a team approach to achieving goals, these efforts contributed to Gerdau's ability to meet budget and timeline constraints.  I would have no hesitation in recommending Barclay Construction Group to others in the future."

"We were awarded the construction of a $1.82 million gallon storage tower in Waterdown, ON at which time we had to subcontract the heavy concrete foundation and support pedestal work.  Barclay Construction Group performed this work for us very safely, efficiently and at a level of quality which equals our own. We would certainly recommend Barclay for any similar or related work."
