This project was a big challenge for our company as it involved multiple work scopes and materials. As with any project it had its challenges at several levels, from design to construction, but the project also had weather issues and was in process as the Covid-19 pandemic first broke out. When roofers were declared ‘essential workers’ it allowed us to keep moving forward on our work scope, provided we followed the new CDC guidelines for Covid-19.
In spite of a global pandemic and some bad weather moments, we were able to complete all the work scopes on time (timelines were extended due to these extenuating circumstances). This was probably the most challenging commercial project we have done…EVER. We feel it came out great.
