Project judgments and procurement conclusions
System pricing optimization does not reduce the thinning of the geomembrane or the weight of the geomembrane, but rather allows the underlying layer processing, protective layering and film specifications to meet the penetrating and durability requirements. When there are more underlying sharp stones, improving the protection of the fabric grade or improving the coating layer may be more economical than simply adding thick film; on the contrary, high waterhead, chemical media or long life projects cannot use thick film to compensate for poor coating performance.
Cost accounting
Key parameters and quick judgement tables
| Program variables | Conditions for lowering costs | It's not possible. |
|---|---|---|
| Optimizing the baseline | Reducing the risk of local penetration | Performance of film and welding |
| Improving the protection of fabrics | Large disruption of construction or raw materials | Chemical compatibility |
| Increased volume width | The site can be hung open | CQA on the ground |
| Selection specifications | Differences in regional risks | Unified Minimum Design Requirements |

Acceptance points and common risks
- Just compare yuan/square meterThe construction is not containing any waste, damage or protection.
- Protecting the thin fabricThe damage to the soil layer may be exposed only after water has been stored.
- Too much specificationsThe cost of allocating the goods will increase the cost of mis-delivery, mispaving and batch management.
Cost accounting
Steps to landing
- Establishing risk segmentsThe bottom of the pond, the slopes, the road junctions and the pipeline are assessed respectively.
- Comparison of systemic solutionsUnified quality of materials, construction, testing and maintenance costs.
- Make a sceneVerify the impact of protective layers, feed materials and equipment passage.
- Locking the interface responsibilityThe contract for the delivery of membranes, cloth, soil and conductive materials at the border is written.
