We build to make a difference
Innovative construction solutions for a sustainable future
At OSS Contracting Company, we combine experience and forward-looking vision to deliver innovative, precise, and high-quality projects that exceed expectations and leave a lasting positive impact on the community and the built environment.
The idea
Ensuring effective management of the design process in the most critical aspect of creating a successful outcome for any project is what we guarantee at OSS, as we meet all our clients’ requirements through the design process while creating an efficient and practical design.
Design
OSS believes in thoughtful and systematic thinking in every aspect of the project. Taking sufficient time to consider the requirements and individual dynamics of each project element ensures that we can focus not only on achieving our clients’ goals but even surpassing them for the better.
Construction
The construction phase is the culmination of the thinking and design processes, and the actual realization of the vision behind the project while meeting the desires of all stakeholders. OSS approaches the construction phase of all our projects with the ambition to create exceptional quality.
About us
An engineering vision that makes a difference
OSS was established in 2006 to become one of the leading companies in the general contracting, construction, and building sector. Since its inception, the company has strengthened its presence through years of precision in execution, reliability in delivery, and creativity in design to meet market needs, reinforcing its position as a trusted partner in managing and executing high-quality projects with high efficiency in both the public and private sectors, as well as its presence in integrated projects.
The idea behind OSS emerged from a firm belief that engineering is not merely a construction process, but an integrated system that begins with planning and professional design, passes through environmental and sustainability studies, and ends with precise execution and quality assurance.
From this standpoint, the company was established as part of an integrated system that adds value to the market through a threefold integration of the engineering innovation cycle founded by entrepreneur Moajab Al Rashid:
• Integrated urban and architectural planning and design through OSS Design
• Environmental studies, sustainability services, and solutions through Sustainability Symbols
• High-quality project execution and reliable delivery through OSS
Through this integration, OSS has become a model for companies that combine experience, forward-looking vision, and strict commitment to quality standards to deliver comprehensive engineering solutions that elevate the client experience.
