Sheet TC-04 · Example report

Example: 7-storey aged care building

The client wanted to know if the five accommodation levels above a concrete podium could be built in timber, and who could supply it.

What we found

  • The building suited timber: the floor layout repeats, spans are modest and the square plan makes stability simple.
  • Five systems were considered. Loadbearing CLT and glulam post and beam were developed, with a timber-frame wall option on the CLT scheme.
  • Australian and overseas suppliers were compared on landed cost, including freight, lead times and treatment options. Both were kept in play for pricing.
  • Common areas were designed for 120-minute fire resistance by charring, so the timber can be left exposed.
  • Risks flagged: CLT lift cores, CLT balconies, and wet areas over timber. Mitigations were recommended for each.
