How much does it cost to install a square meter of water and electricity?

In our market, there are four ways to calculate the labor cost of new house decoration and water and electricity installation: directly put forward the lump sum price according to the square area, according to the actual length and according to the actual working day;

Calculated by square area: at present, high-voltage electricity is generally calculated by 35-45 yuan per square meter (if the price is a little more complicated), and drainage is calculated by 35 yuan per square meter;

Lump sum price: after the plumber directly investigates the site, he will estimate the approximate labor cost according to the actual situation and experience, and then quote the lump sum price; Generally, as long as the actual workload remains unchanged and there is no emergency, the plumbing trade union will charge according to the lump sum price proposed in advance;

According to the actual length: 20 yuan per meter is calculated according to the length of electric conduit, and 25 per meter is calculated according to the actual length of upper and lower water pipes;

Settlement according to actual man-days: according to 300 yuan/man-days, according to actual installation man-days * man-days unit price = labor cost.
