A Comprehensive Guide to Working Platforms for Drill Rigs and Cranes – Ep 089

In this episode, we talk with Thomas D. Richards, Jr., P.E., D.GE, a consultant at Nicholson Construction Company, about working platforms for drill rigs and cranes. We delve into what working platforms are, why they are essential for geotechnical engineers, their utilization challenges, and how they can contribute to their effective use. Engineering Quotes: Here Are Some of the Questions We Ask Thomas: What is the role of working platforms in geotechnical engineering and why are they essential for diverse construction projects? Can you provide examples of construction projects where the use of working platforms significantly improved project safety, and what factors contribute to their effectiveness in such cases? What are some of the common challenges and misconceptions that geotechnical engineers face when designing and implementing effective working platforms for drill rigs, cranes, and other large pieces of equipment? What are the cost and logistical considerations when bringing material onto a site for ground improvement? Could you elaborate on your role in committees and how it has influenced the development of guidelines and best practices for working platforms? For those listening to this podcast and wanting to do the right thing, where can they find existing or upcoming resources to guide them? What is the most challenging aspect of effectively utilizing a working platform, and what would be the correct approach to overcome it? How is the modification of a constructed working platform managed, particularly when drilling through or alongside it? How do you envision the future of working platforms in geotechnical engineering design, and are there any emerging technologies or trends that could significantly impact their design and usage? Could you share some key insights or memorable moments from your travels and interactions within the geotechnical community? What advice would you give to aspiring geotechnical engineers, particularly those interested in working platforms and enhancing safety on drill rigs and cranes? Here Are Some of the Key Points Discussed About Working Platforms for Drill Rigs and Cranes: Working platforms are important for construction projects, especially in geotechnical engineering. They provide a safe place to work with equipment. These platforms are often made of gravel on top of poor soil. This helps them stay stable and prevents accidents like overturned trucks. In the early stages of rigging, smaller rigs were primarily used that didn’t exert much stress on the ground, making them easy to stabilize. The use of larger rigs and foundation elements in later stages prompted a more analytical approach to prevent overturning. In geotechnical engineering, understanding the scale of operations and allocating appropriate resources for ground preparation is crucial. This includes using more gravel than initially anticipated for large-scale projects. Such thorough preparation significantly enhances safety on the job site. It's possible to strategically plan the grading and use of materials like a load transfer platform. This approach not only enhances site safety during the installation of elements like Controlled Modulus Columns (CMCs), but also ensures that the materials have a beneficial use after the completion of the work. Committees play a crucial role in addressing technical challenges in the field. These challenges may arise from various sources and are discussed collectively within the committee. The first mention of working platforms, for instance, was at an ADSC meeting in 2005, where the Safety Committee was asked about their experiences with site conditions. While progress may take time, it is a natural part of the process of developing and implementing new guidelines a...
