Yes definitely. Find someone.
When I build (12 times in Thailand already over many years) I am there every morning to check with builder on the days work, and then onsite at least 3-4 hours a day. Then I can rectify problems or changes immediately on the spot.
On one build I was out of the country for a while and hired a farang friend (qualified builder) to oversee the construction. Plus using telephone, online chats and videos the build went well.
