Eliminate uncertainty from your piping construction estimates. Are you a Cost Estimator, Construction Manager, Engineer (Mechanical, Chemical, or Petroleum), or a stakeholder in an EPC company? In major industrial projects, an error in calculating welding and erection man-hours can mean the difference between a profitable project and a significant financial loss. Estimator's Piping Man-hours Tool is a direct, technical guide designed to solve one of the most complex challenges in industrial construction: accurate man-hour estimation for piping in Gas Compressor Stations. What you will find in this manual: Far from academic theory, this book uses a real-world practical example to break down the methodology step-by-step, teaching you how to structure professional calculations: Reliable Base Values: How to establish solid MH/DI (Man-Hours per Diameter Inch) standards for carbon steel. The "Material Factor" (API 5L): Discover how high-strength steel (X60/X70) and demanding welding procedures (preheat, special electrodes) drastically impact productivity. The Cost of the Environment (Brownfield): Learn to quantify hours lost to Work Permits, safety lockouts, and the complexity of operating within existing live plants. NDE Valuation: A critical cost and time comparison between traditional Radiography (RT) and Phased Array Ultrasonic Testing (PAUT). Line Completion: Correct estimation for cleaning, hydrostatic testing, and pipe drying. Structured Methodology: A clear separation between direct labor and indirect labor (detailed in Annex A). Real-World Case Study: The book concludes with a detailed analysis of the fabrication and erection of a 30'' spool, applying all correction factors to visualize the real impact on execution times. Stop relying on vague global factors. Use this tool to build solid budgets, defend your estimates to clients with technical arguments, and control actual productivity on-site.
