"THE GREATNESS OF A NATION CAN BE JUDGED BY THE WAY ITS "NATURE" IS PRESERVED". (Parminder Singh) The purpose of setting up this group is to invite colleagues to share their views on the importance of accessibility of data such as for foundations and building structures during and post construction works. Availability of info like as-built details for e.g. before and after an earthquake could be beneficial such as to guide emergency services and for other reasons. For e.g. after a fire, info for remodelling work can be planned straight away. Building modifications can be made with info stored on the web. There are also opportunities to improve existing designs into sustainable concepts. Currently there are XML and GML formats used in recording drilling logs in the US. The intention is to make this accessible on the web. Recent threat of floods in many countries affect buildings with basements. Prior warning to owners could save lives and damage to property. The ability to access the right data helps in vast cost recoveries in the event of disasters. However issues such as privacy laws and liability issues might not appeal to certain quarters. In congested places such as in urban areas, the need to know about adjacent buildings is important if  a new building is being designed. Some countries such as Hong Kong maintain records of about 60,000 man-made slopes at their Geotechnical Engineering Office (GEO) out of which about 40,000 are government owned slopes. Pls see info on their safety system, http://hkss.cedd.gov.hk/hkss/eng/slopeinfo/index.htm. Info on buildings can also be obtained from the building control department, Gov't of Hongkong on case to case basis. We think this is a step in the right direction and hope colleagues can share more info with us on how to raise this issue at the right level. There are possible spin-offs and welcome colleagues sharing them. Recent development on smart technologies such as sensors can be used for long term monitoring of large infrastructure projects such as rail, highways etc. It will serve the purpose of knowing that billions of dollars spent on infrastructure projects are kept under tight control. An example of such work is at Cambridge, http://www.cam.ac.uk/research/features/infrastructure-revolution/ A database on landslide subsidence was created by USGS for a no. of countries. Pls see, http://isols.usgs.gov/subsidenceDrillDown.aspx.  Monitoring subsidence. land and water movement with inSAR from space is becoming available. A successful data and tool repository is available under Geobrain in the Netherlands. Pls see, http://www.geobrain.nl. The Malayan tiger or "Harimau" is indigenous in SE Asia. It is a fast depleting specie usually found in the rainforests of Malaysia. The reasons for this is changes to their habitat such as forest clearing for oil palm projects or for medicinal purposes or randomly killed if they attack poultry/people in the jungles. Efforts are on the way to save them using various techniques such as "tagging". It is a postive means to learn about their habitat and a good way for us humans to learn about our environment and prepare for the "unexpected".
