Next divide the number of hours by the number of 8-hour workdays within the amount of time you have to complete the project.
. 2 12 032. Total of design drawing man-hours. You can substitute the values with your organizations specific value to determine the man-hour for a specific period for your organization.

F or example if the project mentioned above contains 4 stress critical lines you have to calculate critical lines from PID per stress system on an average then the total number of stress critical lines are 25041000. Man-hour is an integral factor in measuring Health and safety performance. Estimators Piping Man-Hour Manual Estimators Man-Hour Library by John S.

Calculating Piping Man-hour based on Stress Critical Lines. Typical manhours required for each of these activities are as follows. As we know with the cost of man-hours it is easy to calculate how the labor force contributes to the unit cost and the profitability of the product line.
To calculate man-hours start by dividing your project into separate components like excavation construction and plumbing. Pipe welding man-hours Butt weld. Lets for example if for a project 250 stress packages are estimated out of which 20 are highly critical 100 are moderately critical and rest 130 are lower critical then manhour estimates will be 12 X 2050100401303010680 considering 50 man hour for a highly critical package 40 man hour for a moderately critical stress package and 30 man hour for lower critical stress.
Sr ActivityUnit Hours 1 Study. How do you calculate man-hours for piping. Add for co-ordinationoverheads etc.
Independent design drawing checking. So total piping man-hours estimated would be approximately 1000 x 1212000. Activity Unit New Update Piping Specifications 1 Piping Layout.
In this method the total number of stress critical lines are estimated from existing PID. Then that value is multiplied by a factor Normally 12 to 18 depending on the experience of the existing organization. Man-hours estimate for piping equipment design Hagedoorn Mechanical 9 Mar 05 0619 You can use a factor for calculating the engineering work out of the total construction cost 10 and 35 for example12 till 15 for petroplant grass root revamp 25 en 35fine chemical 17 till 25 grass root.
What you should to do is more practice based on lesson learned as you have it. 12 025. If you want to accurately calculate time to construct a major piping project this will cover you very well.
15 x 10 x 6 900 hours Therefore productivity is equal to 800900 089 units per hour. Then estimate how many hours of labor it will take to complete each component. The man-hours required to perform a task include actual working time and normal non-contributory time.
Estimating 6 working hours per day the total man hours is obtained from multiplying the following. Given manhour tables are result of analyses comparisons simulations and new measures of collected technical bibliography standards catalogues man hours and rates from the European and USA countries verified in practice during the plant erection. PipelinesDesign and constructionHandbooks manuals etc.
With proper and conscientious application of these data for making estimates the estimator will calculate hourly time. 1 14 029. Cutting pipe in case of changes.

A basis I used was a system for estimating the value of erection works of a German Company LINDE which I completed and modified. Hi Its not standardized but seems look common practice to define man-hours for design engineering.
