Key parameters and quick judgement tables
| Projects | The formula | Explanation |
|---|---|---|
| The slope is long | √(horizontal run² + vertical rise²) | Calculate by slope |
| Net area of paving | The bottom + the side + the platform + the firmness | Drawing of the deductions and increases required |
| Acquisition area | Net floor area x 1+ loss rate) | Assessment of regular and complex sites |
| Theoretical weight | Area x thickness mm x about 0.94 | HDPE estimates not accepted |

Project judgments and procurement conclusions
The net floor area of a rectangular pool can be calculated by the floor area + the side slope area + the platform / the firmness of the area. The side slope area must be slope length, not flat width. Purchasing area = net floor area × 1 + loss rate; theoretical weight approximation is equal to area × thickness × mm) × 0.94 kg/m2, in fact, the product density, pass and excess pounds are proportional.

Steps to landing
- The geometry of the partitionDo not use the irregular field as a rectangle.
- Calculating slope lengthCreate a size chart for each slope and platform.
- Adding the amount of processingThe first is the use of a single line of connecting, fastening and sealing pipes.
- Changing the number of volumesThe actual volume length is taken upwards and the remainder is reviewed.

Acceptance points and common risks
- Unit of size confusionThe mix of m, mm and m2 makes mistakes even bigger.
- Theoretical weight is over poundsThe difference between the width, the core and the packaging are not the same size.
- Repeated calculation of lossesIf the version software already contains a link, it should not be overlapped again.
