GOC325525 - Upgrade Building Envelope

Request for Consultant Services

This is a life cycle extension event of the 6 story building's exterior components to prevent further deterioration and to avoid future costly repairs (water infiltration). Currently failure of the silicone joints has caused panels to start to detach.

The scope of work is to perform an upgrade to the building envelope as sealant joints between the concrete panels are in varying stages of failure. The concrete block walls are experiencing some mortar joint cracking. Wall penetrations in the mechanical room penthouse are poorly sealed and louvered vents are not flashed. Windows are double glazed aluminum framed with excessive air leakage. Pressure wash and coating of split face concrete block walls with an elastomeric coating. Replace sealants for entire building ‐ windows and panels. Replace sealant between all exposed aggregate concrete panels at spandrels and at shear walls. Pressure wash concrete panels and once dry, apply a coat of clear masonry sealer.

Fall Protection will be required.

See Appendix 7 - Building Exterior Condition Assessment completed to support this project for complete scope of work.
