quite important You need to look at where your work is. Sometimes we go to compare the prices of large contractors. The price will be expensive. Small scale contractors won't get the job and project owners will lose. But if we take only the minimum wage to calculate, there will be no contractor who accepts it because it will lose. If you don't have time to see the work, you have to hire someone to come and see the technician again, it will be more expensive. If it is a system work that requires a lot of specialized capabilities, it will cost more.
Start calculating from the minimum wage.
We cannot estimate the minimum wage, but we can use the minimum wage as a base for additional calculations. Let's try to figure out how many people use in a day and how many work points. And then estimate the price from the wages
Suppose a worker receives 400-500 baht for a worker, 300 baht for a skilled person (based on the minimum labor cost of 300 baht). The technician and his worker can walk 20 meters (buried in the wall) a day of pipe, and be able to see 35-40 baht per meter. Installing PVC pipes is considered easier than other systems because the equipment only has glue and joints. This is the price that the contractor will think. If we hire a contractor again, we may have to calculate the contractor's profit as well.
