Planning notes for Thai projects
Thai public holidays
Songkran (April) and New Year close ports and customs for several days – we build them into the schedule.
Auspicious dates
Many Thai owners hold a ceremony for raising the first column (Sao Ek). Tell us the date and we deliver the first columns ahead of it.
Estate & municipal approvals
Allow time for the estate or local authority review; our quick drawing revisions keep it short.
