Characteristics of steel structure engineering technology Advantages of steel structure engineering First, the weight of steel structure is light.
The steel consumption of light steel structure is about 20-50kg/m2 generally in the industrial and civil buildings without crane beams, and thus it is better applicable to some areas with soft foundation.
Primarily, the quality of steel structure engineering detail drawing should be ensured.
Quality control in the stage of steel structure engineering construction Most work of steel structure engineering includes welding and installation construction in the stage of construction.
The key steps of steel structure engineering quality control Steel's on-site testing and accepting, marking-off and material preparation, cutting, tube's processing, steel structure welding, fasteners connection engineering, steel member assembly engineering, steel member preassembly engineering, single layer structure installation, rack installation, pressing sheet metal engineering, and steel structure painting engineering are very important and key steps of the steel structure engineering quality control.

Analysis of Influence Factors of Tunnel Surrounding Rock Stability and Researches of Its Control Methods Xiankai Bao College of Architecture and Civil Engineering, Inner Mongolia University of Science and Technology, Baotou 014010, Inner Mongolia, China bxkzlm@163.com Key words: surrounding rock stability; bolt, tunnel; non-destructive testing; working load.
Monitoring and forecasting of tunnel engineer stability is an important method to guarantee rationality of engineer design and construction and safety of production [4].
Conclusion Rock stability in tunnel engineer is a very complex project and under many factors influences in actual engineering.
But most testing methods depended on experience in actual engineering.

Despite the potential advantages and a consistent number of studies and applications in fields like precision engineering and aircraft engineering, there are no relevant studies related to applications in architecture.
Different types of applications have been proposed in aerospace engineering and robotics.
Small and large structures have also been proposed in the civil engineering field.

Business Procurement Software Application for Project of Universal Studio of Singapore Li Lihua North China University of Water Resources and Electric Power No.36 beihuan road, Zhengzhou Henan China 450011 Email: lilihua1965@163.com Key words: project, business procurement software, program, full workflow cost, supplier Abstract: Project procurement management is the substantial basis of engineering project and also critical about executing project process.
This civil engineering projects are in underground and on the ground two parts, the basements of which covers an area of 80,000 square metres, all reinforced concrete structure, approximately 75,000 cubic metres of concrete, steel of about 17,000 tons.
Considering the characteristics of this project, procurement procedures are as follows: » The works area materials person under field requirements submitted material requirements; » Internal audit by engineering materials group, if recognized, referred to the project manager reviews; » Purchasing Department receiving the material demand, if signed, in recognition of material specifications, prices, orders placed after purchase, usually issued orders by fax; » Order issued and confirmed by the supplier to complete purchases, while marking on the demand to prevent repeat purchases; » Demand form finishing on a monthly archive, review purchase invoices, settlement payments.

Waste from the Destruction of Industrial and Civil Infrastructure as a Resource in the Post-War Revival of Ukraine RODIONOV Dmytro1,a 1Dnipro University of Technology, Dmytra Yavornytskoho Ave., 19, Dnipro, 49005, Ukraine abigrody81@gmail.com Keywords: waste from uncontrolled destruction (WUD); disaster waste management; post-war reconstruction; hazardous debris; WUD classification.
The civil war in Syria (2011–2020) also left behind tens of millions of tons of rubble: in Aleppo alone, more than 15 million tons of construction waste had accumulated by 2017, with a total of more than 130,000 buildings destroyed [7].
Handling this type of waste requires the involvement of military engineers and explosives experts: first, the munitions must be rendered harmless (through controlled detonation or removal for disposal), after which the debris is cleaned of metal and other residues.
Syria (2011–2021): Civil war left cities like Aleppo and Homs in ruins, with tens of millions of tons of debris [7].
This initiative involves the creation of a centralized WUD management system: more than 260 sites of destruction have been surveyed for mines and ammunition [25], and local specialists are being trained in safe methods of handling hazardous waste (in particular, more than 80 Ukrainian engineers have undergone training in assessing asbestos-containing debris and ammunition risks).
