41 - Industrial and Heavy (engineering) Construction Industries

Industrial and heavy construction contractors primarily engaged in the construction of projects other than buildings. Establishments classified here undertake complete projects which will cover several components, varying proportions of which can be either sub-contracted to trade contractors or can be done by the general contractor's own labour force. Establishments that do some construction work but which are primarily engaged in another activity such as utility operation, manufacturing or mining are classified by their principal activity.
