Saudi Engineering Group International

What Saudi Engineering Group International does

Saudi Engineering Group International (SEGI) is a privately held, 100% Saudi-owned engineering design and consultancy firm headquartered in Dammam, Eastern Province. Founded in 1979 by Dr. Abdullah A. Ali Alsaihati (originally as Saihati Engineering & Consultants in 1978), the firm has grown into one of the larger multidisciplinary engineering consultancies in the Kingdom, with over 1,000 professionals across design (200+) and project management consultancy (780+) teams and offices in Dammam, Al Khobar, Riyadh, Jeddah, and Abha. SEGI is family-controlled, with the Alsaihati family occupying the Chairman, Vice Chairman/Group President, CEO, and multiple board seats; the firm consolidated all its entities into a single professional partnership in 2022.

SEGI's service portfolio is organized around three core lines: General Engineering Services (GES) covering feasibility, DBSP, pre-FEED, FEED, detailed design, shop drawings, and BIM/CADD with iPlant integration; Project Management Consultancy (PMC) including construction oversight, site supervision, scheduling, cost control, and risk management; and Specialized Engineering Studies such as power system analysis (load flow, short circuit, protection coordination, transient stability, arc flash), process safety (PHA/HAZOP/SIL/HAZID), hydraulic, environmental impact, cathodic protection, and stress analyses. Underlying tools include ETAP and PSCAD for electrical studies and 3D BIM/CADD workflows. Revenue is generated through contract-based professional services fees on enterprise engagements.

SEGI operates an enterprise B2B go-to-market, serving Saudi state-owned and major industrial clients across Power & Energy, Oil & Gas, Water Utilities, Petrochemicals, Infrastructure, Mining, and Health & Education. Visible anchor clients include Saudi Aramco (approved GES contractor since 1992), National Grid SA, Project Development Company (PDC), Ma'aden, Tasnee, Marafiq, Petro Rabigh, and Gulf Cryo. Distribution is exclusively direct, with no resellers or self-service channels, and growth is driven by multi-year framework agreements, tender wins, and partnerships with international engineering firms such as the 2014 Amec Foster Wheeler partnership (AFWAPFC) and project collaborations with Larsen & Toubro, CEEC GEDI, EKACOM, and Al Osais Contracting. The firm is leveraged to Saudi Vision 2030 capex in power transmission, renewables, mining, and oil & gas infrastructure.
