Regarding the issue of material costs in construction and installation projects (brothers who know, please give me some guidance)
Thread Content
Questions about material costs in construction and installation projects: Five main materials: Cement, steel, wood, glass and asphalt. Under construction: Is the main material cost already included in the material fee in the quota? Do I need to deduct the main material fee when approving the subcontracting progress payment? Under installation work: The usage amount of the main material fee in the quota is expressed in brackets, and there is no base price. So this means that it is not included in the material fee in the quota, right? So where can I check the cost of the main materials? Is it based on the monthly market information prices in various cities? If the discussion with the owner is to calculate based on the market information price in June 2009, then when calculating the cost of main materials, should the material price difference be adjusted based on the market information price in June? In addition, to give an example, when a scaffolding company builds on-site scaffolding, who purchases the paint on the surface of the scaffolding? Does it belong to us or do they purchase it themselves? If our company purchases supplies, do we need to deduct this part of the cost when approving the progress payment? My point of view is that there is no need to deduct it, because the owner's request is that the paint materials be purchased by our company. If the shelf company purchases it itself, does our company still need to add this part of the money to the shelf company?
All materials for civil engineering projects are included in the quota. If the material is supplied, of course it will be deducted. If the subcontractor does not provide the materials himself, of course he will be deducted. The main material cost of the installation project is generally not included in the quota, and the usage amount is expressed in brackets. If you buy it yourself, you need to enter the quota and fill in the price into the material unit price of the software. As for the price, it depends on the contract. If it is an information price, it will be based on the information price during the contract period. If it is based on market price, then you have to ask the owner to confirm the price of the materials you want to buy before purchasing. When executing a contract with an information price, because the information price cannot cover too much, the price of materials not included in the information price also requires a visa. About painting the shelves. Our unit has its own shelves, so we do all the painting ourselves. If you rent it from outside, of course it is a matter for the recycling materials company. I don't know about the other things, let other experts give you some advice!
