Blue Cross and Blue Shield of MN
Complete restoration of the original roof system was necessary on the main building at Blue Cross and Blue Shield of Minnesota. Complete removal
down to the existing deck, installation of a new fire barrier and modified roof system was then installed by the roofing contractor.
1.
Re-roofing of Blue Cross and Blue Shield main
building at 3535 Blue Cross Road, Eagan MN.
2. Fall support and netting used on the roof to prevent debris from falling off the building.
3. After the roof was clear of debris resulting from the demolition, lighting was installed so that crews could work throughout the night and therefore not disturb BCBS employees during the day.
4. Ramps installed over the existing expansion joint to allow for movement of material without causing damage to the wood expansion joint.
5. Existing vapor retarder over the metal deck. This
vapor retarder was split in a number of areas and
did not act as a true moisture barrier.
