3. Demolition / Reconstruction
We suggest a policed demolition, because the BOI building is surrounded by high-rising buildings. This will avoid damages on the other buildings. An 40m high crawler crane equipped with an hydraulic cruscher is necessary. This crawler crane will be placed on the west side of the BOI building on an 20m high sand chute. Than the crane is in position to reach the stairs at the top of the building. The whole demolition must be made with bucket and nipper. The bulk material must be taken away first. After that the crane will crush the other parts of the building.

All buildings surrounding the BOI building will be covered with tarpaulins. The roofs will be covered with wood.

It must be secured, that the street traffic will be stopped. The employees work under HSE order. The neighbored buildings should not be used.
On desire of the BOI the job should be finished as soon as possible. We are planning an work schedule of 24 hours/day in three task groups. We expect a period of six weeks.
