South Africa's civil engineering industry faces a challenge: procurement processes that prioritize the lowest bidder over qualified firms. Looking abroad, successful models offer valuable insights for reform.Many countries utilize a qualifications-based selection (QBS) approach. Here, experience, expertise, and past performance determine a shortlist of qualified firms. This ensures a pool of capable candidates, not just the cheapest.Another option is a two-stage selection process. Firms initially compete based on qualifications, followed by cost proposals. This balances value for money with the expertise needed for a successful project.Some countries embrace a "best value" approach. This factors in experience, innovation, safety record, and social responsibility alongside cost. This holistic assessment identifies firms best suited to deliver the project's goals.Implementing these models requires a fair and transparent evaluation process with clear criteria for each selection factor.By learning from international models, South Africa can reform its civil engineering procurement. Shifting the focus from just price to qualifications and value will ensure the selection of the best firms to deliver high-quality, sustainable infrastructure projects.
Autorenporträt
Dr. Chopra, for your Advanced Mathematical Modeling course, I propose "Nonlinear Tools: Theory Meets Diverse Problems." This book breaks free from the limitations of linear models and dives into the fascinating world of nonlinear mathematics. We'll bridge the gap between theoretical concepts like chaos theory and practical applications, equipping you with powerful tools to tackle real-world complexities. "Nonlinear Tools" delves into core principles, exploring nonlinear dynamics, complex systems, and the numerical methods crucial for solving these problems. We'll also analyze nonlinear differential equations and their applications across various fields. But this book goes beyond theory. We'll embark on a journey to see how these powerful tools are used in physics, chemistry, biology, even economics, finance, and social sciences, showcasing their versatility in modeling intricate systems. Furthermore, recognizing the growing importance of nonlinear tools in data analysis and AI, the book explores their role in machine learning and control systems, highlighting their problem-solving potential. "Nonlinear Tools" is a valuable resource for researchers, scientists, and engineers encountering nonlinearity, and a captivating introduction for anyone interested in the power of this branch of mathematics to revolutionize how we approach complex problems across diverse disciplines.
