Q2. Using Revit and the project used from week 6 to 8 prepare a schedule for the following
a. Walls
b. Doors
c. Windows
d. Material – Concrete/Wood

Ans:

AIM

To prepare schedule for the walls, doors, windows and materials (concrete/wood)

INTRODUCTION

A schedule is a tabular display of information, extracted from the properties of the elements in a project. A schedule can list every instance of the type of element you are scheduling, or it can collapse multiple instances onto a single row, based on the schedule's grouping criteria.

PROCEDURE

a) Walls

• Open Revit software
• Open existing project file
• Click 'Schedule/Quantities' in the 'Schedules' under the 'View' tab

• Select 'Walls' from category and click 'OK'

• Transfer the necessary fields in the 'Scheduled fields' and click 'OK'

b) Doors

• Click 'Schedule/Quantities' in the 'Schedules' under the 'View' tab

• Select 'Doors' from category and click 'OK'

• Transfer the necessary fields in the 'Scheduled fields' and click 'OK'

c) Windows

• Click 'Schedule/Quantities' in the 'Schedules' under the 'View' tab

• Select 'Windows' from category and click 'OK'

• Transfer the necessary fields in the 'Scheduled fields' and click 'OK'

d) Material – Concrete/Wood

• Click 'Material Takeoff' in the 'Schedules' under the 'View' tab

• Select 'Floors' from category and click 'OK'

• Transfer the necessary fields in the 'Scheduled fields' and click 'OK'

• Using above procedures, material schedule can be done

RESULTS

Schedule for the walls, doors, windows and material is prepared

a. Walls

b. Doors

c. Windows

d. Material – Concrete/Wood

Q3. Using Revit Calculate area and volume of each room in the model with appropriate room tags applied to each room. Prepare a schedule report for area and volume of each room.

Ans:

AIM

To prepare a schedule report for area and volume of each room

INTRODUCTION

A schedule is a tabular display of information, extracted from the properties of the elements in a project. A schedule can list every instance of the type of element you are scheduling, or it can collapse multiple instances onto a single row, based on the schedule's grouping criteria.

PROCEDURE

• Open Revit software
• Open existing project file
• Rooms are already seperated in week 7 assignment
• Click 'Schedule/Quantities' in the 'Schedules' under the 'View' tab

• Select 'Rooms' from category and click 'OK'

• Transfer the necessary fields in the 'Scheduled fields' and click 'OK'

RESULTS

Schedule report for area and volume of each room is prepared

Q4. Using the same schedule using the unit cost rate for materials available in the internet, prepare total cost of materials used in the project
a. Total Cost of Materials
b. Individual Material Take off
