What are the most easily overlooked details in steel structure engineering

The complete calculation of steel structure shall include steel structure manufacturing and steel structure installation, fire prevention and anti-corrosion coating, etc. Some people think that some bidding control the price, and the unit price of steel structure is only calculated and manufactured. Is this right? However, the charging of steel structure engineering is a detail that is easy to be ignored.

When the processing plant completes production, the construction site only needs to install steel structure works (including grid roof). The on-site human and material resources, production investment and safe and civilized production guarantee are lower than those of civil works. Often, external wall pedal and tower crane are not required, as long as crane is used for hoisting, At this time, the cost of safe and civilized construction measures is carried out according to the component hoisting standard contracted separately. So, in this case, how to determine the management fee?

In one case, the construction enterprise has its own steel structure production plant, and the safe and civilized construction measures are still carried out according to the hoisting. At the same time, considering that it is its own processing plant, the construction enterprise must also pay the production investment and management cost when manufacturing the rigid structure in its own plant, plus the investment in hoisting, so the cost standard of steel structure engineering is implemented according to the construction project.

In the second case, the construction enterprise does not have its own steel structure production plant, and the steel structure is directly purchased by the construction enterprise as a finished product, or the construction enterprise purchases section steel and entrusts other steel structure manufacturers to process it respectively. In this case, the construction enterprise does not pay the management cost of steel component manufacturing and production, and its production and management cost has been reflected in the value of finished steel components. Therefore, in this case, the steel structure shall be included in the material cost according to the finished product budget price determined by both parties, and the project cost standard shall be implemented according to the separately contracted component hoisting project.

Therefore, this is a detailed issue of steel structure charging. Of course, it is limited to the actual settlement, the implementation and implementation of bid control price and bid preparation stage. Once the bid forms a fixed price contract, how to implement its unit price shall be agreed in the contract.
