The supervisor establishes supervision executive detailed rules according to laws and regulations relevant to the country, ordinances, project contract documents and technological data.
It need to examine approaching materials, and deeply understanding management goals of all kinds of nodes in the green construction, at the same time, recording, collecting and clearing up the information data, in order to formulate relative measures of organization, management and technology.
In the process of construction, supply chain is throughout, and it is one of the significant ways implement energy saving and emission reduction in the process of green construction.

Under the high temperature, The compressive capacity, flexural capacity of the concrete column strengthened with different thicknesses CFRP is analysed, and the influence of different cross-section shape is also analysed. so the analytical data and conclusions about the high temperature bearing capacity of concrete column strengthened with CFRP are obtained. 1 Performance of Materials 1.1 High temperature performance of steel reinforced concrete column Under high temperature, the mechanical property of the materials that constitute concrete column degrades as temperature rising[2]. ①concrete: The stress-strain curve of concrete becomes more flat and the summit descends and move right evidently with the rising of temperature, it indicates compression strength degrades, the strain peak amplifies rapidly and the elastic modulus reduces significantly, as is shown in Fig 1; ②reinforced bar: the elastic modulus and the proportional limit of reinforced bar gradually declines with the rising

To keep section areas of two columns equal, the size of rectangular cross section was 200mmx200mm, and the diameter size of circular cross section was 220mm, the thickness of CFRP was 0.334mm, the height of concrete columns were 600mm. then the load was imposed under high temperature, the data was presented in Fig5.
