Exercise
1. Calculate Buildability Score for Wall System.
2. Calculate Buildability Score for Structural System.
3. Find % of windows that has the width and height of 1M
(100mm) modular size.

Steps
1. Create the following Shared Parameters
• Buildability Category = Build_Type
• Labour Saving Index = LS Index

a. Open Shared Parameter
dialog box – Step 1, 2 and 3
b. Create a file to store Shared
Parameters – Step 4
This steps were required only for
the first project.
Steps
c. Create New Parameter Group (Buildability) – Step 5
d. Create New Parameter (Build_Type as Text) – Step 6
e. Create New Parameter (LS Index as Number) – Repeat
Step 6

2. Create Project Parameters based on the shared
parameters created in the previous steps
4 a. Open Project Parameter dialog
box – Step 1, 2 and 3
b. Add Project Parameter – Step 4

Steps
3. Edit Type properties of walls and floors to add values for
Build_Type and LS Index. Refer to COP for Buildable
Design 2011 for the values.

Steps
4. Create Schedule to calculate Buildability Score for Wall
System
Build_Type, and LS Index – Parameters created in previous
Steps.
Length – Default Parameter of Wall
Percentage and BD Score – Calculated values (Refer to Next Slide)
11
Steps
Percentage
1. Give a Name,
2. Choose Percentage
3. Choose a filed as “Length” and
4. By <Grand Total>

Steps
BD Score
1. Give a Name,
2. Choose Formula
3. Formula = “40 * Percentage over build type * LS Index”

Steps
4. Create the Schedule for Floor to calculate Buildability
Score for Structural System
Formula = “45 * Percentage * LS Index”

Steps
5. Find the Modular Windows using Schedule
Default Parameters of Window – Type, Width and Height
Calculated Values and Formulas
Mod Width – “Width - ((rounddown(Width / 100 mm)) * 100 mm)”
Mod Height – “Height - ((rounddown(Height / 100 mm)) * 100 mm)”
is Modular – “and(Mod Width = 0 mm, Mod Height = 0 mm)”
Non-Modular Count –
“if(and(Mod Width = 0 mm, Mod Height = 0 mm), 0, 1)”
