The TTP-6 pocket method prevents this by wrapping the membrane into a formed concrete pocket before the railing post is set, requiring proper coordination between structural and waterproofing contractors.","tags":["waterproofing","railing-penetration","balcony-construction","membrane-installation","scope-coordination","ttp-6-detail","construction-specification"],"key_entities":[{"name":"TTP-6 Pocket Method","type":"technology","confidence":0.95},{"name":"S60 membrane","type":"technology","confidence":0.9},{"name":"scope coordination failure","type":"concept","confidence":0.85},{"name":"balcony waterproofing","type":"concept","confidence":0.9},{"name":"railing post penetration","type":"concept","confidence":0.88},{"name":"flood test","type":"concept","confidence":0.8}],"classification":"reference","language":"en","confidence":0.85,"provenance":{"model":"claude-haiku-4-5","tool":"@stacklist/be@0.1.0","confidence":0.85,"timestamp":"2026-09-23T10:39:58.622Z"},"token_counts":{"approximate":578,"cl100k":542},"content_hash":"sha256:a6ecd1dc7e04aa2357d4680a824603600ce7b4e02403293c9d564ad7b6597030","acp_version":"0.2","body_available":true,"body_tokens":578,"visibility":"public","agent_accessible":true,"status":"final"},"_links":{"self":"/api/public/card/d6a6a4de-29aa-49ce-82f1-47ab0e0cc410.json","html":"https://stacklist.com/card/d6a6a4de-29aa-49ce-82f1-47ab0e0cc410","md":"/api/public/card/d6a6a4de-29aa-49ce-82f1-47ab0e0cc410.md","stack_json":"/api/public/stack/ccc8a635-1426-4960-958d-568d07671c5e.json"}}
