The Application of the Complete Decomposition Model in Analyzing the Incontrollable Construction Cost FANG Li1, a, MA Xin2,b 1 Economy and management institute, Tongji University, Shanghai 200092, China 2School of Civil Engineering, Chang’ an University, Xi’an 710061, China afangli0601@gmail.com, bmin1016xin@sohu.com Keywords: Civil engineering.
To illustrate, the decomposition on construction cost changes of a small civil project is carried out.
And the direct engineering cost is the sum of the aggregate prices of subentry engineering.
(17) To the whole direct engineering cost, the change of branch engineering is: (18) In the index form, then: (19) (20) A Case Study There is one small civil project whose settlement exceeded the budget significantly.
For each branch engineering, the foundation engineering, the concrete and reinforced concrete engineering and the earth and rock engineering contribute more than 90% of the exceeding budget; as well as the flooring engineering and the wall and cylindrical engineering also play an positive part in exceeding budget.

Recently, the safety of existing civil engineering structures attracts more and more attention.
The long-term strength of concrete plays a key role during the assessment of safety and durability for civil engineering structures.
The strength of concrete will gradually decrease during the service of civil engineering structures.
Introduction As the development of economy, the safety of civil engineering structure has received more and more attention.
For ensuring the safety of civil engineering structure, the condition assessment periodically is needed.

How to identify the damage of the plate is one of the hot issues in the civil engineering fields.
There are some problems among the theory, methods and practical engineering applications.
A method is presented for determining damage location and degree of civil engineering structures based on model testing of two-dimensional steel plates.
How to identify damage in the elastic plate becomes the hot issue of the civil engineering field.

This work presents the most important advances in 3D printing in civil engineering, specifically, a critical review of the thermal and environmental benefits of 3D printing on building construction.
However, some industries are just realizing the potential of 3D printing and one of which is the civil engineering construction industry.

The concept that the civil engineering infrastructure may be streamlined through the use of Smart technology has been mooted for well over a decade.
Within the civil engineering portfolio bridges have consequently seen by far the greatest proliferation of experimentation with sensing systems.
This particular fibre optic sensor is now well established and accepted within broad sectors of the civil engineering community and has evolved from being an instrument under test in its own right to an instrument which can be used to test and monitor civil engineering construction procedures.

After fulfilling the e-learning of e-government in Yunnan, the system will give the training for civil servants from 53 departments.
This isn't a real e-learning, though it also lists some course such as spoken-English training, Java script and senior system engineer, etc
Lower quality of the civil servants' training Compared with the west countries, the government training in China remains room to develop.
Thus, it can be plugged into web browsers when civil servants use it as a learning assisted tool.
V.Conclusions E-learning in the civil servants' job-training is attracting interest not simply as a tool for innovating the civil servants' job-training and developing education system, but also for prompting social cohesion , actualizing educational welfare and encouraging international cooperation.

Structural Modal Parameter Identification Based on Natural Excitation Technique Qiang Pei 1,a, Long Li 1,b 1Research ＆ Development Center of Civil Engineering Technology, Dalian University, Dalian 116622, China apqiem@163.com, bdxl269@163.com Keywords: natural excitation technique; structural modal parameter identification; structural engineering Abstract.
Natural excitation technique has found an increasingly wide utilization in civil engineering field.
Civil engineering technology has entered the high-speed development period as well[1].
Then it was gradually applied in the field of civil engineering and has a wide range of development.
But they all meet the engineering requirements.
