Setting up a building site. a) Read the following text. All planning work has been done – now it’s time so set up a site. Places have to be defined for the site office, containers for the workers, storage areas and heavy-plant, like a crane. Additionally, access roads for trucks or excavators must exist. b) Then, draw the site plan of the building site you currently work on and describe it to your partner. For example, define the area where you can find the site office. Useful phrases: Read the text about excavation work and write down five important facts into your exercise book. Excavating the ground is one of the most dangerous types of construction work, since one cubic meter of soil can weigh as much as a small car. We’ll talk more about specific dangers later. Depending on the project, first preparatory earthworks have to be done. This means clearing the site of the topsoil including trees and bushes. Then excavation work can start for anything from trenches for utilities (water, gas, electricity) to foundation slabs or cellars as well as other construction projects like streets or parking areas. Before digging the ground, the excavating company should check the subsoil and the level of ground- water. Weak subsoil must be properly secured by sloping, benching or shoring the area, while too much groundwater requires the use of a pump. 01 A2–B1 Word bank excavate ausheben, graben soil Boden, Erdreich excavator Bagger trade fair Messe 01 set up einrichten site office Baubüro plant Baumaschine 02 excavation Aushub, Erdarbeiten weigh wiegen earthworks Erdarbeiten clear beseitigen, roden topsoil Mutterboden, Humus trench Graben utility Leitung, Anschluss foundation slab Fundamentplatte subsoil gewachsener Boden secure sichern slope böschen, abschrägen bench abtreppen shore pölzen pump Pumpe example online On the right side, there is … In the upper left corner, there is … In the middle … 02 A2–B1 First you must clear the site of the topsoil.

Excavating the soil on site When Peter was a little boy he dreamed about operating excavators one day. Now he is in the construction industry. Together with his colleagues from school, he visited the “bauma” – the world’s leading trade fair on construction machinery in Munich – and felt like a little boy again. Have you ever been to the “bauma?” Did you know that it takes place only once every three years? 90 Unit 21 Nur zu Prüfzwecken – Eigentum des Verlags öbv
