Segment Reporting [Abstract] |
Segment Information | Segment Information The Company’s reportable segments are: (i) U.S. Gas Utility Services (“U.S. Gas”); (ii) Canadian Utility Services (“Canadian Operations”); (iii) Union Electric Utility Services (“Union Electric”); and (iv) Non-Union Electric Utility Services (“Non-Union Electric”). Canadian Operations was previously known as Canadian Gas Utility Services or “Canadian Gas”. The segment was renamed to reflect the expanded scope of services offered by the segment following the Company’s acquisition of Connect, which is included in this segment. The addition of Connect was the only change in the composition of this segment. The Company’s president and chief executive officer serves as the Company's chief operating decision maker (the "CODM"). The Company’s reportable segments are established in consideration of differences in services, geographic areas and workforce composition (union vs. non-union). The Company has not aggregated any operating segments into reportable segments. The CODM reviews short-term and long-term trends and budget-to-actual variances in gross profit to assess performance across the different segments in determining where to allocate resources. U.S. Gas U.S. Gas provides comprehensive services, including maintenance, replacement, repair, and installation for local natural gas distribution utilities (“LDCs”) focused on the modernization of customers’ infrastructure throughout the United States. The work performed within this segment includes solutions for all stages of utility work and is performed primarily within the distribution, utility-scale transmission and end-user infrastructure, rather than large-scale, project-based, cross-country transmission. In addition, U.S. Gas performs other underground services, including water and fiber, and has an in-house fabrication shop providing pipe and component assembly. The Company is able to cater to the needs of its gas utility services and energy customers by serving union and non-union markets. Canadian Operations Canadian Operations provides comprehensive services, including maintenance, replacement, repair, and installation for local gas and electric utilities and energy providers. A majority of the work performed in this segment is focused on distribution, urban transmission and end-user interface under MSAs for gas and electric utilities. This segment also provides storm response services and performs construction of electrical systems used in renewable energy projects. Union Electric Union Electric provides a comprehensive set of electric utility services encompassing maintenance, replacement, repair, upgrade, and expansion services for urban transmission and local distribution infrastructure within union markets. The work performed within this segment is focused primarily on recurring local distribution and urban transmission services under MSAs, as opposed to large-scale, project-based, cross-country transmission, and services are primarily focused on infrastructure between the substation and end-user meter. In addition to core electric utility infrastructure, this segment provides heavy industrial work, including civil, mechanical, electrical, and fabrication (component assembly) services. Non-Union Electric Non-Union Electric provides a comprehensive set of electric utility services encompassing maintenance, replacement, repair, upgrade and expansion services for urban transmission and local distribution infrastructure within non-union markets. The work performed within this segment is focused almost exclusively on recurring local distribution and urban transmission services under MSAs as opposed to large-scale, project-based, cross-country transmission, and services are primarily focused on infrastructure between the substation and end-user meter. Other Other consists of any corporate and non-allocated transactions. Revenue and gross profit by segment are presented below (in thousands). Revenue amounts presented are revenues with external customers, and intersegment revenues were not material.
