Preparing Schedule & Cost Estimation for a building using REVIT

Preparing Schedule and Cost Estimation for a Building using Revit

Introduction:

Schedule:

• 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 into a single row, based on the schedule grouping criteria.
• The schedule can be created at any point in the design process. If any changes are made in the model that affects the schedu;es, 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 consists of nodes
• Dynamo and revit together can be utilised to model and analyze complex geometrics, automate repetitve process, minimise human error, export data to excel files 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.

1) Use the shortcut keys in Revit discussed in class to complete the following tasks and list them below
a. Using 3D model create a section box
b. To create similar doors and windows in a floor plan layout
c. To reduce the thickness of lines visible in plan views
d. To apply override settings to a floor in the model section view
e. To increase the range of visibility in a plan view
f. To select the previously selected items
g. To add annotations to the model views
h. To bring the model elements in line
i. To rotate the model elements
j. To move an object to another location
k. To copy a model element
l. To mirror an element about an axis
m. To create an array of model elements

Aim: To list all shortcut keys we used in the Revit software

Result:

A.Using 3D model create a section box - BX (Section Box)

B. To create similar doors and windows in a floor plan layout - CS ( Create similar)

C. To reduce the thickness of lines visible in plan views - TL (Thin Lines)

D. To apply override settings to a floor in thw model section view - VG ( Visibility Graphics and Override setting)

E. To increase the range of visibility in a plan view - VR ( View Range)

F. To select the previously selected items - Ctrl + < ( Reselect )

G. To add annotations to the model views - DI ( Dimension)

H. To bring the model elements in line - AL (Align)

I. To rotate the model elements - R ( Rotate)

J. To move an object to another location - MV ( Move )

K. To copy a model element - CO ( Copy )

L. To mirror an element about an axis - MM ( Mirror )

M. To create an array of model elements - AR ( Array )

2) 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

Aim: To prepare a schedule for the given elements.

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 into a single row, based on the schedule grouping criteria.
• The schedule can be created at any point in the design process. If any changes are made in the model that affects the schedu;es, it automatically updates to reflect those changes.

Procedure:

step-1: Open RVT 2023

step-2: Open Project 2 Architectural file

step-3: Go to View tab

step-4: Select Schedule

step-5: Select Schedule/quantities

step-6: Schedule dialogue box will open

step-7: Select Walls from Category

step-8: Select Appropriate Scheduled fields

step-9: Click OK

Wall Schedule:

Step-10: Again Go to Schedule

step-11: Select Doors

step-12: Select Prior Schedule fields

step-13: Click OK.

Step-14: Again Go to Schedule

step-15: Select Windows

step-16: Select Prior Schedule fields

step-17: Click OK.

Step-18: Again Go to Material takeoff

step-19: Select Floor

step-20: Select Prior Schedule fields

step-21: Click OK.

Step-22: Again Go to Material takeoff

step-23: Select Doors

step-24: Select Prior Schedule fields

step-25: Click OK.

Step-26: Again Go to Material takeoff

step-27: Select Windows

step-28: Select Prior Schedule fields

step-29: Click OK.

Result:

Hence, Created schedule of materials used in the project.

A. Wall:

B. Door:

C. Window

D. Materials:

3) 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.

Aim: To create and calculate Room area and Room tags and also create schedule report for all rooms.

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 into a single row, based on the schedule grouping criteria.
• The schedule can be created at any point in the design process. If any changes are made in the model that affects the schedu;es, it automatically updates to reflect those changes.

Procedure:

step-1: Open RVT 2023

step-2: Open Project 2 file

step-3: Go to Architectural tab

step-4: Select Room tab

step-5: Go to Plan view

step-6: Select the room to tag all rooms

step-7: If Two rooms interconnected, go to Room Seperator

step-8: Go to modify tab

step-9: Select Line and Rectangle option to select Room Boundary

step-10: Again go to Room tag option

step-11: Double click to modify room name and number of each room
