Therefore, to improve safety on the work site, such conditions must be detected before an accident occurs [5].The physical aspects of safety on construction sites cover the unsafe work conditions could be summarized as follows [5]: 1) Fire prevention 2) Housekeeping 3) Scaffold/mobile tower 4) Sandblasting 5) Cartridge operated tools 6) Power tools/machine and equipment 7) Excavation 8) Heavy equipment 9) Concrete formwork 10) Gas/electric welding 11) Health and welfare 12) Compressed gas 13) Transportation 14) Air compressors 15) Cranes and lifting devices 16) Safety administration 17) Temporary electric 18) Special items Furthermore Poon, Wang and Zhang [4] have proposed following items from a safety point of view on the construction site: 1) Civilized construction site 2) Scaffolding 3) Excavation supports and formwork 4) Personnel protective equipment and protection at openings 5) Use of electrical appliances 6) Material hoist and external lift
Engineering means selection of techniques and material which are generally included design and technical specifications on the basis of strategic decisions and organizational policies of construction projects.

Finally, the correction requires accurate knowledge of the thermal expansion coefficient of the test specimen, which may be hard to assess for an inherently variable material such as concrete.
For an elastic material with Young's modulus E, and in the absence of any thermal effects, the stress is related to the elastic strain ε by σ = Eε and hence a strain can be deduced from the measured frequency.
To remove the temperature effect, a control gauge is used, which is mounted on an unloaded sample of the same material as the test specimen, and positioned as close as possible to the specimen, so that they may be assumed to experience the same temperatures.
