Preparing Schedule & Cost Estimation for a building using REVIT

01Q:

Introduction:

Schedules:  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.

The schedule can be created at any point in the design process. If any changs are made in the model that affects the schedules, It automatically updates to reflect those changes. 

Using revit softwares cost estimates can also be developed. By providing the unit cost of materials, total cost can be derived.

The other concept coming under this section is Visual programming. Here, the visual programming tool is Dynamo.It is an open source visual programming language for revit, written by designers and construction professionals. It is a programming language that allows to type lines of code; while also creating an algorithm that consist of nodes. 

Dynamo and revit together can be utilised to model and analyze complex geometries, automate repetitive processes, minimise human error, export data to excel files and other file types not typically supported by Revit. Dynamo can make design process more efficient, with an intuitive interface and pre-made scripting libraries available as well.

02Q:

Aim:

To prepare the schedule for the following:

a. Walls
b. Doors
c. Windows
d. Material – Concrete/Wood 

Procedure:

• Initially open the architectural model created previously.
• Then go to view tab --> Schedules --> Schedule/quantities.
• Now, select the required fields.

a) Wall schedule:

 

 

 

• Now, for the wall schedule choose the parameters for scheduling and then click ok.

 

• The wall schedule is prepared as given below:

 

 

• Hence, the wall schedule is prepared.
• Similarly, prepare the door schedule, window schedule and material concrete/wood schedule.

b) Door schedule: 

• View--> Schedule --> schedule/quantities.
• Select door.

 

• Now, select the parameters to be considered for doors.

 

 

 

• Door schedule is given as:

 

 

c) Window schedule:

• View--> schedule --> schedule/quantities.
• Now, select the category as window:

 

• Now, select the parameters to be considered for windows.

 

 

• The window schedule prepared is as given below:

d) Material- Concrete/Wood

• View--> schedule --> material takeoff.
• Now, select the category as floors:

 

• Now, select the parameters to be considered for floor material.

• Material takeoff scheule is given by: 

RESULT:

The wall,door,window & material schedule have been prepared.

 

03Q:

AIM:

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.

Procedure:

• Go to view --> schedule --> schedule/quantities.
• Now, select the category as rooms:

• Now, select the parameters to be considered for room.

 

• The room area schedule is given as:

RESULT: 

Room area schedule is prepared.

 

04Q:

AIM: 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

Procedure:

1. For walls:

• Go to view tab --> schedules --> material take off.
• Select the category as Door.

 

• Now, select the parameters for doors.
• Now, we have to include the total cost parameter which is a calculated quantity.
• For this go to add calculated quantity.

 

• The door material take off is given as:

• Similarly, prepare for wall, windows, floors and furnitures material takeoff schedules.

 

 

 

• The Window material take off is given as:

 

 

 

• The Floor material take off is given as:

 

 

• The Wall material take off is given as:

 

• The Furniture material take off is given as:
