(15) Business Segments

The Company offers general contracting, pre-construction planning and comprehensive project management services, including planning and scheduling of manpower, equipment, materials and subcontractors required for the timely completion of a project in accordance with the terms and specifications contained in a construction contract. The Company also offers self-performed construction services: site work; concrete forming and placement; steel erection; electrical; mechanical; plumbing; and heating, ventilation and air conditioning (HVAC). As described below, the Company’s business is conducted through three segments: Civil, Building and Specialty Contractors. These segments are determined based on how the Company’s Chairman and Chief Executive Officer (chief operating decision maker) aggregates business units when evaluating performance and allocating resources.

The Civil segment specializes in public works construction and the replacement and reconstruction of infrastructure. The civil contracting services include construction and rehabilitation of highways, bridges, tunnels, mass-transit systems, and water management and wastewater treatment facilities.

The Building segment has significant experience providing services for private and public works customers in a number of specialized building markets, including: high-rise residential, hospitality and gaming, transportation, health care, commercial and government offices, sports and entertainment, education, correctional facilities, biotech, pharmaceutical, industrial and high-tech.

The Specialty Contractors segment specializes in electrical, mechanical, plumbing, HVAC, fire protection systems and pneumatically placed concrete for a full range of civil and building construction projects in the industrial, commercial, hospitality and gaming, and mass-transit end markets. This segment provides the Company with unique strengths and capabilities that allow the Company to position itself as a full-service contractor with greater control over scheduled work, project delivery and risk management.

During the six months ended June 30, 2018, the Company recorded a charge of $17.8 million in income from construction operations (an after-tax impact of $12.7 million, or $0.25 per diluted share), which was primarily non-cash, as a result of the unexpected outcome of an arbitration decision related to a subcontract back charge dispute on a Civil segment project in New York that was completed in 2013.

A reconciliation of segment results to the consolidated income before income taxes is as follows:
