Materials and Method Various methods of workspace analysis have been discussed in literature and even applied before.
Paths are spaces required for the movement of materials, people, and other resources.
The method does not take into account workspaces such as path (moving to materials, movement of machines and mechanisms).

The system includes function generator, power amplifier (AG1016), materials testing system (MTS810), high-energy low-pass filter, pad, sensor, oscilloscope, computers and on-line test specimens and fixture.
Material is AZ31 magnesium alloy, the yielding stress is 199MPa.
Then ultrasonic attenuation coefficient (is proportional to the frequency squared) of materials increases with micro-cracks growing, so the attenuation of the second-harmonic is greater than the attenuation of fundamental wave.

Therefore, it is necessary to establish an information data base of construction cost which is more suitable for valuation system of bill of quantity, and adjust quota timely according to new process and new materials, so as to render it to keep certain synchronism and advancement with market to improve the scientificalness of engineering project valuation decision, thus realizing the objective of effective management of construction cost.
For each detailed catalogue (unit project), list the people, material, machine and other expenses of unit project.
Japanese official has set “economic investigation committee” and “construction price committee” to investigate economic indexes of various constructions, and “reckoning benchmark”, so as to get actual situations of various building materials and expenses.
Moreover, it also includes information data concerning construction cost such as basis document, relevant expense confirmation, material price information, etc.
