Technical Calculation and Estimator's Man-Hour Manual Marko Bulić
is a widely recognized resource used by professionals in the petrochemical and construction industries to accurately assess labor and material requirements for plant erection www.estimations.info Overview of the Manual
This manual is the result of over 30 years of field experience in technical calculations estimations.info
. It provides standardized tables for estimating the man-hours (
) required for complex industrial tasks, specifically focusing on the erection of process and chemical plants Core Content and Chapters
The full 239-page manual covers 14 distinct categories of work www.estimations.info Piping & Pipelines: The Verdict: Is the PDF still "Best"
Extensive tables for above-ground piping installation, including factors for pipe sizes, schedules, and materials like carbon and stainless steel Structural & Process Equipment:
Man-hour rates for steel structures, process equipment installation, and storage tanks (cylindrical and spherical) Mechanical Tasks:
Detailed estimates for welding, flame cutting, and thermal insulation Specialized Protection:
Chapters dedicated to corrosion protection and weight factors www.estimations.info Estimate Points:
A unique section on "estimate points" where one point typically equals one man-hour at a 90% Productivity Efficiency Percentage ( cap P cap E cap P estimations.info Technical Methodology: The PEP Factor Key Features of the "Best" Technical Calculation Manual
The manual emphasizes that no two projects are identical. Estimators must determine a Productivity Efficiency Percentage ( cap P cap E cap P
for every specific job before calculating the final labor value estimations.info Standard Basis:
Tables provide base values that do not refer to a generic condition but to precisely determined PEPs verified through practical plant erection estimations.info Adjustment:
Project managers must use the manual’s data alongside factors like site conditions, material multipliers, and local labor skill levels to refine the estimate estimations.info Availability and Access
The Verdict: Is the PDF still "Best"?
Yes—for conceptual estimates and field verification.
No—for massive, data-driven EPC bids. and safety delay factors. However
The manual lacks modern composites (FRP piping), automation, and safety delay factors. However, no software has yet replicated the intuition built into Page’s original numbers.
