What this detail covers
- How studwork base rails/soleplates interface with the slab and adjacent SIP panels.
- Keeping moisture control layers (DPC/DPM) continuous at the base.
Key steps
- Set out studwork positions from the drawings (centres and wall lines).
- Fix the treated soleplate/base rail to the slab per schedule; maintain DPC continuity where required.
- Keep studwork aligned so later linings and service zones remain true.
Checks
- Base rails are straight and fixed to the schedule.
- Stud centres match the specified layout (common 600c/c or as designed).
- Clear separation/allowance where movement or tolerances are required.
Common mistakes
- Fixing through moisture layers without the specified detailing.
- Drifting out of line which creates poor finishes later.
Indicative only: always follow the engineer’s fixing schedule and the project drawings.
