In the mid-nineties, I was heading a civil design department for a large EPC contractor in South East Asia.  We had received an order to build a paper plant.

The primary building in a paper plant is the paper machine building. A typical paper machine building is about 300 m long. The building typically has two floors, one at ground level, and one at about 7.5 m level. The paper machine is installed on a foundation that is not connected to the building. The machine is accessible from the machine hall
