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

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)”
