4 Purpose of the WebLEM Committee This Committee exists to serve the needs of the MCAA membership. As such, we are committed to providing a resource as well as education of the MCAA membership in the areas of estimating plumbing and piping construction work. We are committed to timely responses to member questions, requests for information and recommendations.
5 Purpose of The WebLEM Committee The Committee will research, calculate and publish labor units for new materials and methods for plumbing and piping products. –For a product to be considered for inclusion in the LEM, it must meet the following criteria: The item must be available commercially for a period of at least two years. The item must be nationally available to all members for the sizes listed in the product literature. The product must be involved in work that is typically executed by plumbers and/or pipefitters. The MCAA membership must have an interest or need for the labor units related to the product. Any new item must be specifically different than other items currently in the LEM from the standpoint of labor units. Naming of all items contained in the LEM will be a generic description of the material or joining method to avoid commercialism as much as reasonably possible.
6 Purpose of The WebLEM Committee The Committee is charged with keeping historical records of the development of data contained in the LEM. The Committee will ensure the existing labor units are kept up to date with the goal being to have accurate, consistent units for all materials and methods. The accuracy begins with utilizing empirical formulas developed over many years that have proven to generate uniform labor units for all materials and joining methods. The Committee is committed to updating or revising existing labor units for a specific product if it is determined that our MCAA members are factoring a specific material or joining method significantly different than the rest of the data in the LEM.
7 Purpose of The WebLEM Committee The Committee is committed to providing educational opportunities to the MCAA membership on how to use the WebLEM and the information contained in it appropriately. The Committee shall have representation from all geographical areas of the Country as well as representation from all disciplines within the plumbing and piping construction industry.
8 What the WebLEM Committee Does Reviews and updates the information in the Labor Estimating Manual (LEM) on an ongoing basis. We meet two times a year to review homework and publish new and corrected labor units. The Committee makes decisions on what items should be included in the LEM. The Committee members calculate the labor units for the LEM using empirical formulas developed and proven out over many years to be accurate and consistent. Members of the Committee represent all areas of our industry such as commercial, industrial, plumbing, HVAC piping, industrial piping, etc.
9 What is the WebLEM? The MCAA web based Labor Estimating Manual contains labor units for a vast variety of activities related to the mechanical construction industry specific to piping and plumbing trades. It is not an estimating system, rather a database of labor units proven to be the most accurate and complete collection in the world for our industry. In the past, the LEM Committee provided updates on a yearly basis. Those updates consisted of new information as well as revisions to existing information. However now, updates to the WebLEM occur on a more frequent basis.
10 WebLEM’s Key Benefits All information in the WebLEM is fully available to any subscriber from any computer with internet access. Much faster to locate information than former formats and includes complete search capabilities. Updates from the LEM Committee are made real time giving subscribers instant access to new and updated information. All data tables are downloadable in MS Excel or CSV formats for local use. All subscribers are notified automatically via email anytime a change is made to data in the WebLEM. Those emails contain links directly to the specific tables and the data points changed will be highlighted for the next 12 months.
11 WebLEM Access All MCAA Member Companies receive full access to the WebLEM free of charge as a membership benefit. Each Company has been given a username and password for access. They have also been given a username and password for “Company Contact” user access. The “Company Contact” is responsible for keeping the company profile information up to date in the WebLEM. This individual will also receive the “update emails”. The WebLEM will automatically change passwords for all users on a set basis for security reasons. New passwords will be emailed to the “Company Contact”, who in turn will distribute to all users within your Company.
13 WebLEM Home Page A short Flash Demo is provided for a quick 4 minute overview of the WebLEM’s basic use. In addition, there’s a pdf file located in the Help menu that can be downloaded or printed. It also has basic instructions on the WebLEM’s use. User profile information can be updated from the link in the Login box. There are several links to more information on MCAA’s website as well as email interfaces you can use to submit questions electronically. There are also Recent Updates, My Bookmarks, and Recently Viewed links located on the right side of the screen.
14 WebLEM Data Tree All data is laid out in a tree structure, and is generally in alphabetical order. Folder names are always in black font. Data tables and files that can be viewed are always in blue font. Once a table is chosen, the font size can be modified if you would like it to appear larger or smaller by clicking on the + or – button on the top of every table. Any data points that have been modified within the past 12 months will show up highlighted in yellow. A paperclip symbol at the top of a column or above a data point indicates there is a file attached that can be viewed by clicking it.
15 WebLEM Data Tree A “breadcrumb” is listed at the top of the page when you are viewing a table. An example of such is LEM Data->Fittings->Carbon Steel (Forged)->Buttweld. You can click any part of the breadcrumb to go back to that portion of the data tree. Notes or diagrams pertaining to tables will be located at the bottom of the webpage after all tables are displayed. It is very important to read the notes associated with each table. On long and/or wide tables, column and row headings are automatically repeated to keep the user from having to scroll to find the labels.
16 Searching, Downloading, Printing A search box is always present in the upper right corner of the webpage. Even most mis-spellings and synonyms are accounted for. “Search Tips” is a link to some directions on how to use the search functionality. You can always go back and view your last search results by clicking on the Search Results menu located on the top toolbar. This function will display the last search performed. All data tables can be downloaded in either Excel or CSV formats by clicking on the link in the upper right part of the page. All tables can be printed by clicking on the print link. Tables are automatically broken into pages both due to width and length.
17 WebLEM Administrative Capabilities LEM Committee updates are made in real time. Each change to data is logged automatically. Change logs are emailed to subscribers as frequently as needed. Reports can be generated to show most frequent searches, mis-spellings, etc. As a result, the database can be updated accordingly to make access easier for the subscribers. Pictures, pdf files and notes can be attached to any data point, column heading or table. Other pieces of information such as administrative notes and important reference documents can also be attached to any data point for reference by the Committee. The history of all changes made to every data point in the entire database is automatically logged and can be accessed easily.

22 Development of the LEM 22 Labor Estimating Manual
23 History of LEM Created in 1968. Published in 1971. Developed by a committee of contractors / prepared from contractors’ point of view Labor units were developed from a formula, which are reviewed and proven over time –The formula was developed to obtain consistency LEM committee is a Source for contractors questions and comments on labor man-hours Provides a consistent and methodical method of estimating 23
24 Definition of a Labor Unit An Expression in Terms of Man-Hours Required to Install a Unit of Material (i.e., Foot of Pipe), an Individual Item (i.e., Fitting or Valve), a Specialty Item or a Piece of Equipment. 24
25 Elements of a Labor Unit –Material Handling Receiving, Unloading, Stockpiling, Distributing –Joining Type Of Connection, Quantity Of Joints, Type Of Material –“Normal” Pressure Testing –Installation/Erecting Weight (Which Relates To The Handling) Size (Diameter Of Pipe, Fitting / Etc.) 25

43 What’s Next for the WebLEM? In May of 2011, the WebLEM Committee proposed to the MCAA Board of Directors that we should develop and publish an entirely new method of estimating mechanical piping systems and components that we termed the “Joint Method”. The MCAA Board of Directors approved the proposal and since then our committee has been working on this new development. 96
44 What is the Joint Method? The joint method will consist of counting and laboring the number of joints in a system, and adding labor of the installation of items and assemblies based on the “equivalent length” of the item or assembly. 96
45 Why the Joint Method vs. the Fitting Method? The joint method better supports the ability of contractors to identify labor associated with the different labor components of fabrication and installation than the fitting method. See example to explain better. Example Drawing Spool Example Take-Off Presentation 96
