During the excavation of a HOPSCA project group foundation pits in Fujian province, a large pit was excavated by dewatering well group earlier,it caused the water table dropped seriourly in the surrounding blocks and the follow-up foundation pits were excavated with only little dewatering measures. the large range of dewatering in the group foundation pits resulted in the differential settlement of road and cracking of some buildings aroud the group foundation pits.
But the national Codes, local Codes and professional norms in China almost did not make any provisions for group excavation engineering.

It was the first stage for project management information system, and the future vision of system was mainly designed by the metaphor practice of agile system in order to individual modules and appearance became visible, meanwhile, developers and clients can be from different sides to understand the customer field and professional knowledge.
System development example Specific function module of the general model should be chosen according to the characteristics of the project when the agile development model based on bidirectional iteration will be applied and the case that the project management system development for the first phase of the South-to-North Water Diversion Project in Tianjin BinHai New Area, named Caozhuang pumping station project is illustrated in the paper.

This study will aim at stationary pollution sources such as coal-fired boiler in electricity and cogeneration profession, secondary aluminum refinery and cement kiln to construct its professional dioxin emission factors to provide future reference for processing control strategies formulation.
As fire coal is burned in furnace to release energy to heat water or other organic heat carrier such as heat transfer oil et al. to a certain degree or pressure, the boiler will function as a heat energy power device.

At present, this paper discusses the project risk areas covering oil, Marine, electric power, water conservancy (dam), urban transportation, construction, national defense scientific research, international contracting, nuclear power, metallurgy, aviation, etc[2].
From the project characteristics, it is known that it is a kind of high risk project, the technology is complex, equipment professional, social environment, special laws and safety factors.

The extinction coefficient were all about 71400 at 280nm in water.
Due to limited conditions in primary and middle schools’ laboratories, the computers are all micro PC using Windows operating system and lack professional technologists.

The contractor is inactive to the insurance. 0.619 2 The owner/contractor regards the insurance as compulsive request of the government and the bank and has to fulfill it. 0.619 2 The owner/contractor is weak in risk and insurance. 0.611 3 During the process of compensation, the procedure is detailed and the responsibility shifts seriously. 0.597 4 Insurance company is short of professional hands (especially for engineering insurance). 0.589 5 Each part of the project considers the insurance will increase the cost. 0.586 6 The owner isn’t the propeller of the engineering insurance. 0.58 7 Information of the engineering insurance is seriously unsymmetrical because of the complication and professionalization of building engineering technique. 0.572 8 The engineering insurance codes developed is less, the difference of the cost rate level is little and the guarantee contents lack the selectivity. 0.543 9 The owner and contractor only buy insurance for the project with high risks or portion
For instance, four insurance companies such as Ping An Insurance, Pacific Ocean Insurance and the People’s Insurance Company etc paid off 5.6 billion dollars for the water trouble which took place in No.4 line of the Shanghai rail transit in July, 2003 [18].
