Party Wall Drylining QA Checklist

This construction QA checklist supports inspection of party wall drylining for South Thamesmead Phase II. It guides supervisors and subcontractors through checks on bottom and deep tracks, stud spacing and deflection gaps, fire strips and mastic, identification of wall types and junctions, cavity insulation (including 35 kg/m3 mineral and APR insulation), and 90/120 minute fire-rated partitions. It includes verification of IR01/IR02/IR03 riser and smoke shaft walls, timber studs at door jambs, security mesh, screw spacing to a 300 mm maximum, service fixing plasterboard strips, and screed shutters. The checklist emphasizes use of British Gypsum materials, requires photo evidence for key steps, and confirms areas are left clean, with sign-offs from contractor and client.
