This is the most utilized section. It covers everything from fit-up and welding to hydro-testing. It categorizes labor by pipe schedule (wall thickness) and nominal pipe size (NPS).
This section is the most heavily utilized part of the manual. It splits labor into two distinct phases: and field erection . Shop fabrication occurs in a controlled environment and carries a lower man-hour rate per unit than field erection, which happens exposed to the elements and at varying elevations.
Includes tables for installing various pipe sizes and materials (carbon steel, stainless steel) with factors for pipe schedules and coatings.
What is the Technical Calculation and Estimator’s Man-Hour Manual? This is the most utilized section
These manuals are structured around tables that provide baseline man-hour units for specific tasks. These baselines are then adjusted using productivity factors that consider project-specific variables like location and site conditions to create a highly accurate final bid.
