1.10 Plant Layout
This layout, including plans and sections, is a hypothesis of layout because, at this step of the project, the real sizes and the details of the equipment are not well known. The drawing, based on dimensions of standard equipment available in Europe, is suitable to define:
space requirements
approximated position of utility connections
approximated position of power connections
approximated weights to be charged on the foundations
hypothesis of supporting and service steel structures
maintenance area requirements
1.11 Civil works
Excavation works, buildings, open areas, roads and sewers are described (by drawings and specifications) with a detail enough to prepare the bill of quantities of all the components of civil works
