I checked your level and this is my comment:
1. Our drawing request is +130mm.
2. The site 3-side levels varies from +107mm to +145mm.
3. These 3-sides use skimmer short panel.
4. We have a few options now:
1. Option 1: Keeping our +130mm request and ask the client to knock down anything that is more than 130mm.
2. Option 2: Take the new +145mm as the new level and raise all top levels (including gutter side) by +15mm. The new Gutter installation level is –135mm.
