2.1. Balcony Waterproofing/Flashing Mockup
The perimeter flashing has been installed at Level 3. Several items require correction for the Level 1 and Level 2 install as follows:
1. The vertical leg of the flashing at the front edge is slotted between the panel edge and the L-angle structure which is incorrect. It should extend over the exterior side of the L-angle to allow water shedding (see below).
2. The flashing is installed with nails into the deck. It should instead be set into sealant or temporarily taped in place to avoid penetrations into the bottom membrane.
3. The side edge flashing should include a drip edge over the structural tab (see below)
Action Required:
1. PW/U1 to confirm detail and U1 to install remaining components. Avoid penetrations into bottom membrane ply.
2. U1 to leave Level 3 flashing as is and install remaining membrane/components

2.3. Membrane Blistering
PW noted blistering spots beneath the Level 1 SBS membrane. It could not be confirmed if these are the result of membrane discontinuities.
Action Required:
U1 to cut open blisters to confirm if water is present, drain and dry wood surface if necessary, repair as necessary prior to second ply installation.

Final Review
RDH was on site on 2021 05 13 and 2021 06 03 to view the balcony finish components including the decking and wood coating. All items noted in our Site Visit 03 Notes report appear to have been addressed adequately for the purpose of this balcony mockup. This visit serves as the last review for this phase of the mockup work. Sensor monitoring of the wood moisture content will continue for the foreseeable future.
