How to save money for hydropower reform
1, control drawings strict budget
In the signing of the renovation contract, the designer may be asked to present the hydropower reform drawings, and then the materials used in the telephone lines, power outlets, switch panels, network cables, etc. shall be strictly calculated according to the drawings, and then reasonable expenses shall be calculated to avoid excessive increase of the additional costs.
2, mid-term acceptance to avoid rework
In the middle period of hydropower reform, we also need to carry out some acceptance to avoid rework. For example, when the waterproofing of the kitchen and toilets and the buried underground hydropower pipelines are accepted, if the waterproofing of the tiles is found to be unqualified after the completion of the construction of the tiles, the electric lines are blocked, and the plumbing pipes are blocked or leaking, they can only be reworked.
The above is related to the hydropower installation specification and the related knowledge on how to save money for hydropower reform. After reading it, is there any more understanding of this aspect? If you want to know more relevant knowledge, please continue to pay attention to this site information, more exciting, so stay tuned!
