2 WebLEM Update: How to Apply the Work Activity Method for Labor Calculations By: Tim Moormeier and Ron King

3 WebLEM Committee Members Kevin Daubendiek – Humphrey Company, Houston, TX Paul DeBella – DeBella Mechanical, Santa Clara, CA Bob Durr – Durr Mechanical Construction, New York, NY Andrew Hosler – Performance Mechanical Inc, Pittsburg, CA Ron King – Trimble MEP, Toronto, ON Patrick Reilly – John W. Danforth Company, Buffalo, NY Tim Moormeier – U.S. Engineering Company, Kansas City, MO Nick Nikpourfard – Mechanical Contractors Association of America, Rockville, MD Kevin Daubendiek – Humphrey Company, Houston, TX Paul DeBella – DeBella Mechanical, Santa Clara, CA Bob Durr – Durr Mechanical Construction, New York, NY Andrew Hosler – Performance Mechanical Inc, Pittsburg, CA Ron King – Trimble MEP, Toronto, ON Patrick Reilly – John W.

4 What were some of the driving forces which lead to the development of this new method of laboring? Inability to separate labor accurately into shop vs field Inability to account for labor associated with back to back fittings Inability to break down all labor components of a joint Better cost control of labor activities in both the shop or field Inability to separate labor accurately into shop vs field Inability to account for labor associated with back to back fittings Inability to break down all labor components of a joint Better cost control of labor activities in both the shop or field

5 How do we do it today? We establish shop vs field labor hours by: Percentage method Diameter inch method Account for back to back fittings by applying a correction factor Currently no way to break down the components of the joint Some have improvised by determining a “Cap” equals one joint We establish shop vs field labor hours by: Percentage method Diameter inch method Account for back to back fittings by applying a correction factor Currently no way to break down the components of the joint Some have improvised by determining a “Cap” equals one joint

6 What does a labor unit presently include? Example: 6” CS, Std Wt, Buttweld, LR 90° Elbow. The WebLEM states 6.29 hours, which includes: Receiving, unloading, stockpiling, distributing Joining method Type of connection – Buttweld Qty of joints – 2 Type of material – Carbon Steel Wall thickness – Standard Weight Example: 6” CS, Std Wt, Buttweld, LR 90° Elbow. The WebLEM states 6.29 hours, which includes: Receiving, unloading, stockpiling, distributing Joining method Type of connection – Buttweld Qty of joints – 2 Type of material – Carbon Steel Wall thickness – Standard Weight

7 What does a labor unit presently include (Cont)? “Normal” pressure testing – 1.5 X OP Installation or erection Note: The joint and installation make up the bulk of the unit “Normal” pressure testing – 1.5 X OP Installation or erection Note: The joint and installation make up the bulk of the unit

8 What’s the Challenge? No way to account for back to back fittings other than applying a correction factor No way to establish meaningful hours for the fabshop other than applying a percentage or doing a diameter inch calc No way to establish labor hours for components of the joint: Cut & Bevel TIG Root Joint (buttweld) Hydotest Preheat/Postweld heat treat Etc. No way to account for back to back fittings other than applying a correction factor No way to establish meaningful hours for the fabshop other than applying a percentage or doing a diameter inch calc No way to establish labor hours for components of the joint: Cut & Bevel TIG Root Joint (buttweld) Hydotest Preheat/Postweld heat treat Etc.

9 What could we do differently? Break down the labor units into tasks such as: Cut & Bevel Tig Root Purge Preheat/Post Weld Heat Treat Handling of Pipe, Fittings, Flange, Valve, etc Bolt-Up Hydrotest Break down the labor units into tasks such as: Cut & Bevel Tig Root Purge Preheat/Post Weld Heat Treat Handling of Pipe, Fittings, Flange, Valve, etc Bolt-Up Hydrotest

10 What should we call it? The present method of laboring has been named: “ Component Method ” The new method for establishing labor hours for each task has been named “ Work Activity Method ” The present method of laboring has been named: “ Component Method ” The new method for establishing labor hours for each task has been named “ Work Activity Method ”

11 So how does the Work Activity Method work? For the same 6” CS Std Wt BW 90° Elbow, we now have these activities: 6” CS Std Wt Flame Cut & Bevel (single operation) 0.40 x 2 = 0.80 Hours 6” CS Std Wt Buttweld 2.48 x 2 = 4.96 Hours 6” CS Std Wt LR 90° Elbow Installation 0.41 x 1 = 0.41 Hours Total using the Work Activity Method = 6.17 Hours (excluding hydrotest) Total using the Component Method = 6.29 Hours For the same 6” CS Std Wt BW 90° Elbow, we now have these activities: 6” CS Std Wt Flame Cut & Bevel (single operation) 0.40 x 2 = 0.80 Hours 6” CS Std Wt Buttweld 2.48 x 2 = 4.96 Hours 6” CS Std Wt LR 90° Elbow Installation 0.41 x 1 = 0.41 Hours Total using the Work Activity Method = 6.17 Hours (excluding hydrotest) Total using the Component Method = 6.29 Hours

12 Let’s look under the hood!

13 Changes Changes Home page change to promote new Work Activity Method Video and Handouts Introduction Proper Use of the LEM Basis Assumption Correction Factors Addition of the Piping Systems Folder Folder reorganization within the Piping Systems HVAC Hook-Up Instrumentation Misc Labor Operations Home page change to promote new Work Activity Method Video and Handouts Introduction Proper Use of the LEM Basis Assumption Correction Factors Addition of the Piping Systems Folder Folder reorganization within the Piping Systems HVAC Hook-Up Instrumentation Misc Labor Operations

17 Now Let’s See Some Examples! And What This Means To Me? Let’s compare the following: Component Method style of takeoff Work Activity Method style of takeoff to precisely determine the labor required Let’s compare the following: Component Method style of takeoff Work Activity Method style of takeoff to precisely determine the labor required

18 Take this coil hookup for example

19 Take this Isometric Drawing for example

20 So now it’s possible! No need to adjust for back to back fitting situtations Precisely account for all labor activities in the shop vs field Ability to calculate all activities related to the joint Bottom line; The Work Activity Method allocates the labor hours associated with the activities very accurately No need to adjust for back to back fitting situtations Precisely account for all labor activities in the shop vs field Ability to calculate all activities related to the joint Bottom line; The Work Activity Method allocates the labor hours associated with the activities very accurately

21 What if the WAM method just isn’t for me? “I don’t worry about shop vs field or counting the joints…….” “I just want to take off using the same method as in the past; counting widgets……..” No Problem!! Continue performing takeoff using the Component Method just as you’ve done in the past “I don’t worry about shop vs field or counting the joints…….” “I just want to take off using the same method as in the past; counting widgets……..” No Problem!! Continue performing takeoff using the Component Method just as you’ve done in the past

22 But if the WAM Method IS for you You can start using this method immediately Remember to examine your labor productivity factors to account for this new method!!! You can’t use the same factors as used with the component method!!! Be sure to read the Introduction, Proper Use of the LEM and Basic Assumptions Visit each of the folders on the WebLEM contained within the “Work Activity Method” to familiarize yourself and don’t forget to read any footnotes Start producing very precise shop vs field estimates immediately WebLEM committee asks for your feedback You can start using this method immediately Remember to examine your labor productivity factors to account for this new method!!! You can’t use the same factors as used with the component method!!!

23 WebLEM Committee Update Formulating more WAM labor units Cast Iron No-Hub, Copper Sweat, PVC DWV and Pressure, etc. Reviewing the plastics section Reviewing saddles, stub-ins and nozzle welds Formulating Aquatherm labor units Review “Quick Vic” coupling labor units Formulating more WAM labor units Cast Iron No-Hub, Copper Sweat, PVC DWV and Pressure, etc. Reviewing the plastics section Reviewing saddles, stub-ins and nozzle welds Formulating Aquatherm labor units Review “Quick Vic” coupling labor units
