What gisi consulting does

GISI Consulting Group is an employee-owned holding company operating under Global Infrastructure Solutions Inc. (GISI) that unifies nine specialized project management, engineering, and government consulting brands — AIS, Gafcon, GEI Consultants, Hill International, J. Roger Preston (JRP), LiRo-Hill, Palladium, PERC Engineering, and SHEVS IFT — alongside the recently integrated Terrane Geoscience. The Group is incorporated in Delaware with corporate headquarters in Newport Beach, California, and operates from more than 150 offices in over 100 countries with a stated headcount exceeding 10,000. Service delivery is organized around three segments: Infrastructure & Mobility (transport, rail, airports, bridges, urban development), Earth & Water (dams, levees, flood risk, environmental engineering, and the recently formalized Mining & Critical Minerals practice), and Government & Society (economic development, governance, stabilization, and humanitarian programs delivered primarily through Palladium).

The Group's technical stack emphasizes applied digital tools over proprietary research products. Across subsidiaries, GISI deploys AI/ML, digital twins, BIM, GIS, LiDAR, Robotic Process Automation, and Generative AI for project design, simulation, and delivery optimization; Gafcon's specialty industrial systems group adds electron beam (eBeam) processing technology. Underlying platforms include project management systems used on flagship engagements such as the Riyadh Metro (67 km of track across three rail lines for the Royal Commission for Riyadh City), the Los Angeles Metro A Line (~58 miles, with Hill International as program manager), the Mario M. Cuomo Bridge ($3.98B design-build, with Hill providing quality control for the New York State Thruway Authority), Jewel Changi Airport, the Anderson Dam Seismic Retrofit for Valley Water, and the Ngau Tam Mei New Development Area in Hong Kong via the AIS-AECOM joint venture. Hill International is independently ranked as the 3rd largest U.S. project and construction management firm and the 8th largest overall U.S. construction management firm, with more than 90,000 project assignments and over $1 trillion in cumulative construction value.

Revenue is generated through negotiated, project-based professional services fees for project management, construction management, engineering, cost management, and program advisory on large capital programs; pricing is not publicly disclosed and varies with scope, scale, and complexity. The go-to-market is sales-led enterprise engagement, with senior executives and managing directors driving competitive tenders, direct appointments, and long-standing client relationships across government agencies (water, transportation, culture, economic development) and large private-sector developers. Marketing is concentrated in thought-leadership content, project showcases, employer branding, and industry awards (CMAA, RICS, ACEC, Consultancy Middle East) rather than digital advertising. Distribution is exclusively direct, with no intermediaries or channel partners, supported by a network that has grown materially through acquisitions — seven merger-partners added across 2024 and 2025.
