Client: Nova Scotia Trading & Contracting, Doha, Qatar Industry: Electrical & Civil Infrastructure Project Scope: Lightning Protection & Earthing Interconnection Background In large-scale infrastructure projects, ensuring proper earthing and lightning protection is critical for both operational safety and long-term reliability. Nova Scotia Trading & Contracting, based in Doha, Qatar, was tasked with enhancing the lightning protection and earthing system for a network of poles across a project site. Challenge The project required all poles to be interconnected to achieve a comprehensive and robust earthing system. To accomplish this, the engineering team identified Hot-Dip Galvanized (HDG) strand as the ideal solution, thanks to its durability, corrosion resistance, and proven performance in harsh environments. Additionally, the project required a complete set of accessories, including: UT Clamps Wedge Clamps Top Plates Parallel Hanging Plates These accessories were essential to ensure correct installation, secure connectivity, and system stability. Solution Approach The engineering team prepared a detailed cable schedule and technical drawings, highlighting the required interconnections (approx. 3,355 meters of HDG strand). An official Request for Quotation (RFQ) was then issued to suppliers, clearly outlining: The total cable length requirements The accessories needed Delivery terms (Doha, Qatar) The inquiry emphasized efficiency, clarity, and professionalism to ensure suppliers could respond promptly with accurate pricing and delivery options. Outcome Through this structured approach, Nova Scotia Trading & Contracting ensured that all potential suppliers had a clear understanding of the technical specifications and logistical requirements. This not only facilitated faster response times but also improved the accuracy of quotations received, ultimately supporting timely project execution. Key Takeaways Clear documentation (drawings & schedules) is critical for precise supplier quotations. HDG strand provides reliable long-term performance for earthing and lightning protection systems. Comprehensive accessory planning avoids delays during installation. Professional RFQ communication streamlines procurement and builds stronger supplier relationships.
