“EFCO” Front set storefronts, “Guardian” High Performance Low-e. Project was a fully occupied and operable State office building which posed specific challenges and required balance between productivity, tight timelines and the consideration of the occupants working within close quarters. This was a multiple story high rise and was renovated due to energy efficiency mandates and because of multiple leaks (Existing storefronts and glass were removed, brick work renovated and new high performance glass and frames were replaced). Special care was needed and close coordination with masons was required due to new flashings, insulation and weatherproofing required meeting new energy standards and insuring no leaks. End Result ……On time return to normal operations, perfect safety record, no leaks, Minimal punch list and high marks from the State of Michigan, the Architect and the site management of the contractor. A tough job well done….!!!!
