Due to that the human error has great influence on the project risk, human reliability analysis (HRA) has been paid much attention in many engineering projects.
For management of construction materials, the construction materials which are in large amount use should purchased by competitive bidding, which can prevent purchasing inferior materials for saving cost.
For those construction materials whose quality or sources may be unstable, different batches materials should be piled up separately and be tested by supervisor at any time.
Once there are some quality problem, it should be reported to the construction department and the materials should be changed to qualified materials.
Materials supply and consumption should be coordinated with each other.

Sand table is a model made by paper, coin, chessman or other materials in order to simulate the real world for educational or other purpose.
Most engineering students are trained as future senior technical professionals with a teaching system including mainly technical and engineering courses.
Promote Engineering Students to Adapt to Modern Business Management.
Cultivating Engineering Students to Develop Team Collaboration Spirit.
If it is used for cultivating engineering students, there must be some adjustments in order to make the training adaptive for engineering students.

College of Architecture and Civil Engineering, Ningbo University of Technology, Ningbo, 315016, China a chengguoqiang@guigu.org Keywords: forensic engineering, accident investigation, forensic engineering system of bridge Abstract.
Forensic Engineering System Exploration The Proposal Of Forensic Engineering Forensic engineering is the investigation of materials, products, structures or components that fail or do not operate or function as intended, causing personal injury or damage to property.
In addition to this, Vital to the field of forensic engineering is the process of investigating and collecting data related to the materials, products, structures or components that failed.
The NTSB is also in charge of investigating cases of hazardous materials releases that occur during transportation.
Carry out the investigation on the large-scale bridge accidents. 3) Practice is the key Forensic engineering of bridge is a hard task.
