​ The Company’s disaggregated revenue does vary slightly from the Company’s segment reporting due to combining the Industrial and Building Construction into Electrical, Mechanical, & and General, and one legal entity in the Underground Infrastructure Construction segment that performs services other than underground construction that are included in Electrical, Mechanical, & General. The volume of these services is not material to the Company’s segment reporting.
