Concrete pipes are the most popularly used medium for small and medium drainage construction. Construction with concrete pipes cuts cost in formworks, time and also labor costs.
Estimating concrete pipes uses the same procedure for volume method. And also, there is an alternate method of using per pipe piece. This table uses the standard length of each pipe as 1m.
- Concrete pipe thickness is usually 2 inches or 50mm.
- The labeling of concrete pipes is through the inner diameter or the "hole" of the pipe.
