At Horizontal Line Contracting Company, we represent more than just a business venture — we are the result of a powerful synergy between two industry leaders: United Construction Projects (UCP) of Oman and Zawya Al-Sahari General Contracting Est. (ZS) of Saudi Arabia.

This strategic alliance brings together UCP's proven expertise in large-scale construction and infrastructure development with ZS's strong presence in Saudi Arabia's industrial and logistics sectors. Together, we form a dynamic force capable of delivering high-impact solutions across borders.

Our mission is simple yet ambitious: to provide exceptional value through innovation, precision, and performance. We operate with a shared commitment to excellence, safety, and sustainability — whether it's civil infrastructure, drilling and reclamation, roadworks, or integrated manpower and equipment solutions.

Driven by advanced technologies and world-class talent, we are building a company that not only meets the needs of today but is also ready for the challenges of tomorrow. Our vision, “Unified Strength, Unmatched Execution,” defines our path forward — a future built on collaboration, capability, and continuous growth.

We are proud to serve both the Sultanate of Oman and the Kingdom of Saudi Arabia, and we look forward to shaping the region's progress, together.
