Common questions

What else should the bid team know?

Why are no clearance values listed?

Values depend on equipment, application, code, edition and project conditions. Use the approved project basis.

Can vendor drawings define every interface?

No. They provide equipment inputs, while the project team coordinates the overall plant.

Does a layout approve ventilation or fuel design?

No. The responsible discipline approves those systems.
