What is the unit of measurement for the work involved in acid washing and passivation of pipelines and equipment in new chemical projects? Square meters or cubic meters?
It can be specified in the contract, or it can be a lump-sum price
Our consumption and labor hours are both based on area, with weight used as a reference for classification

There are many ways of measurement, and the most common unit is cubic meters (which is directly proportional to the chemicals used for cleaning). When installing a new facility, the construction party usually needs to know the unit price per cubic meter from the cleaning service provider, that is, in yuan/m3. 2. There are various methods for measuring and pricing cleaning services; in addition to the chemicals used, factors such as the difficulty of the work, quality requirements, labor hours, and schedule constraints also need to be taken into account. Therefore, in addition to the usual volume measurement (cubic meters), there is also area measurement for equipment such as heat exchangers (square meters), length measurement for pipes (inches*meters), measurement for valves and fittings (inches*pieces), as well as a comprehensive quotation for the entire small system. . . . . . 3. The specific measurement and pricing methods are determined through negotiation between the two parties and reflected in the contract.
