Process, Documentation, and Compliance

• Before design freeze: Conduct soil investigation (e.g., Sondir 3 points + report) to set foundation type and depth.
• During procurement: Request SNI/recognized certificates, coating classes (roof/steel), and batch IDs on delivery notes.
• On site: Record concrete slump, take compressive test specimens where schedule allows, verify fastener torque, and leak‑test gutters/downpipes.
• Permits: Keep material records and test summaries aligned with OSS submissions, PBG approvals, and the SLF process at handover. Inspectors focus on installed outcomes and conformity with approved specs.
