The new day-care centre “Albrecht-Dürer-Strasse” in Halle (Saale), Germany will provide room for 200 kids and is part of a municipal investment programme. The site is located on the edge of a 150-year-old mine. A special underground mining technique called “room and pillar caving” was used to extract brown coal. This method does not fill the created cavities after extraction of the coal. As a result, the overlying rock layers settle after the mining operations and fill the cavities. It can, however, not be precluded that residual cavities may cause subsidence at the surface of the terrain. Based on these findings, safety measures had to be taken in the area of the open space of the day-care centre.

Over the past 10 years the Bangkok Metropolitan Region has experienced an increase in the traffic volume due to rapid urbanisation. Bangkok Metropolitan Administration as the local government considered it necessary to accommodate the changing traffic flow with the realisation of the Srinakarin – Romklao Road Project. The 11.2km long road is expected to reduce the traffic between the western and eastern region of Bangkok, especially in the Hua Mak Region. A total of 5.5 billion Baht (150 million US$) investment has been made for this project.
