The Power of International Standards Organization (ISO) Certifications

Behind every successful project is a well-run process. At The Weitz Company, operational excellence isn’t just a goal, it’s a standard. That’s why we’re proud to be recertified in the three most recognized International Standards Organization (ISO) certifications: 

• ISO 9001:2015 | Quality Management Systems: helps organizations implement quality management practices to consistently meet customer and regulatory requirements and drive continual improvement. 
• ISO 14001:2015 | Environmental Management Systems: helps organizations identify, manage, and continually reduce their environmental impacts while ensuring compliance with environmental regulations. 
• ISO 45001:2018 | Occupational Health & Safety Management Systems: helps organizations implement systems to proactively prevent work-related injuries and illnesses, ensure worker participation, and comply with health and safety obligations. 

These ISO standards focus on how an organization operates, they are process standards rather than product or service standards. These certifications aren’t about what we build, but how we build it, ensuring quality, safety, environmental responsibility, and sustainability embed into every part of our operations. While the three ISO standards play a critical role, ISO 9001 remains the most recognized and widely adopted standard worldwide. 

ISO 9001: Quality Management Systems focuses on meeting customer requirements and delivering consistent quality. In this context, “quality” refers to all features of a product or service that fulfill customer expectations. Quality management involves the processes and practices an organization uses to meet those requirements, comply with regulations, enhance customer satisfaction, manage risks and opportunities, and achieve continual improvement.  

Tackling ISO 9001 Challenges in Construction 

One of the biggest challenges in aligning ISO 9001 requirements with real-world construction environments is the fast-paced nature of the industry. Construction teams often don’t have the luxury of time to sit down and create detailed quality plans before work begins. Projects are frequently on fast-track schedules, requiring teams to hit the ground running. That’s why having a pre-established, easily accessible quality plan, one that clearly outlines responsibilities, risk controls, and expectations, is critical. It ensures everyone knows their role from the start, helping maintain compliance without slowing down progress. 

The Power of a Consistent Quality Control Plan 

When auditing began last year, a major gap was identified – there was no consistent quality control plan in place. In response, a standardized template was developed, tailored to different market sectors such as Commercial, Industrial and Aviation. This shift, guided by ISO 9001 principles, now ensures that every project starts with a clear quality control plan. Project Managers, Project Engineers and Superintendents formally assign and adhere to the plan, significantly reducing risk, ensuring compliance with contractual and regulatory requirements, and improving overall project delivery. 

Why ISO 9001 Matters in Construction 

ISO 9001 is essential for helping organizations consistently deliver high-quality products and services that meet both customer expectations and regulatory requirements. In industries like construction, it promotes accountability, reduces risk, and strengthens documentation and planning, supports continual improvement – key components for managing complex projects. By improving operational efficiency and building trust with clients, ISO 9001 lays the foundation for long-term business success. In a competitive market, International Standards Organization (ISO) certifications also play a critical role in winning more bids, securing more work, and attracting new customers. 

Extending the Value of ISO 14001 and ISO 45001 

In addition to quality, our certifications in ISO 14001 and ISO 45001 ensure we operate responsibly and sustainably. ISO 14001 drives us to minimize waste, manage resources efficiently, and reduce our environmental footprint across projects. ISO 45001 reinforces our commitment to worker safety by ensuring hazards are identified, risks are controlled, and employees are actively engaged in health and safety programs. Together, these standards demonstrate our commitment to protecting people, communities, and the environment while delivering excellence in construction.
