Post-construction monitoring

Re-opener a permit condition that requires the permitting authority, at a specified time after permit issuance, to review and revise, if necessary, the permit based on new information such as the findings from post-construction monitoring, updated emissions inventories, updated modeling, research, or information on air pollution effects to terrestrial, aquatic, and visibility resources. 

Post-construction monitoring of underfloor voids is usually resisted by housing developers and is not widely undertaken. However, it is possible to monitor die imderfloor voids between membrane installation and selling of a property and this has been carried out on a number of sites. Post-construction monitoring has also been used to demonstrate the effectiveness of underfloor voids in reducing the risk of gas ingress where gas protection membranes have been omitted by mistake or where validation has not been imdertaken. 

Post-construction monitoring is less of an issue with commercial developments and it is widely used to demonstrate the effectiveness of in ground gas migration barriers. 

Guidance is provided on what to look for when inspecting membrane installations and underfloor venting as well as what information to include in a verification report. Guidance on post-construction monitoring is also provided. 

This book presents technical information on pre-design, design, and construction of surface impoundments. Also discussed are operation, maintonance. and monitoring contingency planning and closure and post-closure. 

Strengthen the construction work of the postdisaster recovery ability. Strengthen the postdisaster summary and evaluation work further in communities. Particularly, the managers need finish the post-disaster compensation work for the victims perfectly, in addition, build the disaster monitoring network that is suitable for community reality. Furthermore, it is also very important to make people play part in earthquake relief work. 

The method developed by M.M. Faktor et al. is widely used in semiconductor industry. Based on the same principle an equipment was constructed by POLARON for the British Post. The scheme of the system is shown in Fig. 13. The equipment is suitable for the continuous and automatic determination and is used to monitore the impurity profile in the surface layer of semiconductors with a resolution of about 10 nm in the range 1-50 /xm. Using this equipment operating on electrochemical principle the number of charge carriers can be determined in the surface layer. In addition to this n- and p-type semiconductors can be distinguished (Fig. 14). 

In the last 30 years, many new bridges were constructed, and many old bridges were retrofitted with instmmentation systems. Measurements from these systems during major seismic events are allowed to assess the seismic performance of the structures, the performance of the control systems, and the post-earthquake behavior of the bridge. A number of significant case studies based on SHM (Structural Health Monitoring) data or field investigations are reported below.
