How to design the detailed drawings before the start of the steel structure project?

The detailed drawing design of steel structure engineering is generally carried out by processing units. In order to meet this new requirement, a steel structure engineering should generally follow the following working order:
Factory Detailed Drawing Design Technical Design Unit Examination and Approval Detailed Drawing
Steel Structure Processing, Finished Product Transportation, Field Installation
Material Order Material Transportation Material Transportation
Detailed drawing design in the processing plant has the advantage of combining plant conditions and construction habits, easy to use advanced technology and high economic benefits. Detailed drawings shall be designed in accordance with the technical design drawings of the construction units and the specifications, standards and requirements specified in the contract documents. This requires the construction unit to have sufficient level of detailed drawing design ability.
In order to purchase (order) steel as soon as possible, steel should be ordered at the same time of detailed design. In this way, when the detailed drawings are approved, the steel can arrive and start production immediately.
