An Assembly Consist of
• Items– Fixed quantity per As (Mobilization) – A Custom Calculation (Demolition)– A stored Formula (Item Tables)
• Item Tables– One Dimension– Two Dimension
• Select at Takeoff

Why the effort
• Reduced Errors
• Miscellaneous accessories/connectors selected based on previous selection
• Increased Accuracy
• Decreased Takeoff Time
• Easily Changed
• More Details

Reduced Errors
• Prompts– Select Items Tables base on Construction
Parameters– Include an item that can be calculated on
this pass– Select from brand or style options
• Warnings– Invalid entry or selection provides
warnings

Accuracy
• Calculate variable dimensions– Window Header Length based on
• Window Materials– Wood– Vinyl– Aluminum
• Mull Type– Single– Double– Triple
• # of Jack Studs
![Page 26: Smart Assemblies](https://reader033.vdocuments.mx/reader033/viewer/2022050906/556ac1f2d8b42acd348b48aa/html5/thumbnails/26.jpg)
Jack Stud Requirements
• Most Structural Plans have the # of Jack Studs by width by floor
• Create a formula table that reflects those requirements
• Modify as need for each project
• No need to constantly refer to the table
• Creates a basis for conceptual estimates

Jack Studs By Width & Floor
5’ will fined the next Value in the table
3 required

Header Length
Header CalculationRough Opening +( (# Jack Studs * 2 Sides)* Stud Width)
(36+ 2+ ( 3 * 2) * .125) / 12

Material Length Required
Thus a 3’ door would require a 5’ Header
