This document discusses how building information modeling (BIM) can shift interior design workflows from CAD to a more collaborative BIM process. Key benefits of BIM include parametric modeling that allows for quick drafting and revisions, integrated 3D modeling for visualization, and optimization of schedules and quantities for cost estimation. The document outlines BIM's advantages at each phase of design including coordination, specification generation, quantity take-offs, and facility management. BIM is presented as allowing interior designers to be more integrated into architectural BIM files from project start, reducing errors and improving collaboration between disciplines. Qualifications for an interior design BIM coordinator are identified to help practices transition their work to the new BIM-based workflow.

1. BIM for Interior Design
Shifting of Design workflow
JEFF HONG

2. What is BIM ?
Building Information Model
BIM = One Source of All Building Information

3. Benefits of BIM Process
 Parametric Ability (Quick Drafting)
 Work Sharing (Collaboration)
 3D Capabilities (Easy Visualization)
 Optimization of Schedule & Quantities (Quantity control in Model)

4. Work Flow of Project
 CAD (Computer aided Design) Process
 2D lines means just lines
 2D lines is just line
 Each sheets or drawing within the document set had
to be drawn individually one by one
 No intelligent connection among them
 BIM (Building Information Model) Process
 2D Lines means information
 Document can be set from Model directly
 Model are interdependent & share intelligence

5. Process Methodology
 CAD Process
Line Method
 Work sharing capabilities are limited
 BIM Process
Collaborate Method
 Work Sharing is part of BIM process

6. Design Phase
 Pre-Design (CAD)
 Scope of works
 Project Information
Text information
 Space Program
 Pre-Design (BIM)
 Scope of works
 Project Information (Location)
Source for analyzing daylight
 Space Program
The speed & ease of creating space area calculation

7. Design Phase
 Schematic Design (CAD)
 Conceptual design
 Developing space plans
Developing individual CAD drawings
(Floor/Ceiling/Elevation…)
 Design Options
Create separate design option
 Material Consideration
 Preparing Presentation
 3D Rendering
Additional work & cost
 Schematic Design (BIM)
 Conceptual Design
 Developing space plans
Create plans by using integrated model database (One Click)
 Design Options
Able to create multiple options in one model
 Material Consideration
Analyze sustainable material for green project
 Preparing Presentation
Drag & Drop
 3D Rendering Create any angle views from model

8. Design Phase
 Design Development (CAD)
 Refine & revise design
Revise CAD drawing individually
 Finish Specification
Creating material specification manually
 Material Quantities
Get assistance of estimator
 Lighting consideration
Use as reference for documentation
 FF&E Specification
Making document manually
 MEP Coordination
Coordinated CAD file
 Design Development (BIM)
 Refine & revise design
Parametric ability to revise instantly (data synchronized)
If element is moved, all related documentation updated instantly
 Finish Specification
Generate material specification from BIM directly
 Material Quantities + Cost Estimate
Create material takeoff & cost estimate
Focus on interior finish quantities only
 Lighting Consideration
Not only providing detail information but also using for rendering
 FF&E Specification
Create schedule from model Information directly
 MEP Collaboration
Integrated ONE BIM file to collaborate

9. Design Phase
 Construction Document (CAD)
 Prepare Construction Document
All sheets (Floor/Demolition & Construction/
Ceiling/Finish/Furniture/Elevation/Section/
Detail/Schedules/Legend/FF&E Specification/
Finish specification)should be created one by one
(Time Consuming in Process)
 Revision (CAD)
Revise document per sheet individually
 Facility Management (CAD)
Providing specification & separate CAD file is
used as reference to maintain facility
 Construction Document (BIM)
 Prepare Construction Document
All sheets can be created from embodied model information
database directly (includes schedule, take off & cost estimate)
(Time Saving in Process)
 Revision (BIM)
In parametric modeler system, all related documentation is instantly updated
 Facility Management (BIM)
Providing facility information in ONE embedded BIM Model
BIM provides fingerprint of the over its lifecycle

10. Additional BIM Advantages
(Implemental Tools)
 Green Design Analysis (LEED Credit)
(ECOTECT ANALYSIS)
 Crash Detection (Inspect virtual construction)
(NAVISWORKS)
 4D /5D Simulation (Construction / Budget simulation)
(NAVISWORKS)
 Facilities Management (Management building after construction)
(REVIT)

11. Current Project work flow
 Architecture – use Building
Information Model to process
project
 Structure / MEP also provides BIM
support to integrated with Arch.
Model
 Interior Design – still use CAD
process to create Construction
Document regardless of Arch. BIM
file (No interoperable file between
Arch & Interior)
 Interior designer has been worked
as part of coordinator in CAD
process

12. Shifting work flow toward BIM
 All staffs (Arch. MEP. Owner. Interior designer…) can
involved project from early stage to end. It leads project
to be reduced miscommunication & error which can occur
during traditional CAD process
 Integrated collaboration workflow (ONE BIM)
 Ability to inspect crash detection & simulate construction
process to catch mistaken during construction in virtual
world
 Eliminate much of the repetitive & mundane tasks
traditionally associated with CAD Program
 Focus on design itself instead of individual CD Sheet &
revision coordination internally & externally

13. BIM Work Flow in Interior Design
(How BIM can be effected in Interior Design process ?)
 Parametric capabilities (Includes easy CD
Sheet & revision)
 Managing Design option
 Interior focus finish & FFE quantity
 Quick visual creation in design
 Green Design analysis (Energy & Materials)
 Crash detection , 4D Simulation for ID

14. Qualifications as ID BIM Coordinator
A. Role as bridge between Arch. & Interior Design BIM Process
B. Utilizing BIM software from the point of interior designer angle (Revit Certified)
C. Capability of setting up & managing BIM folder & files
D. Knowledge of BIM process & Software interaction (Revit, Navisworks, Ecotect Analysis…)
E. Ability to solve BIM technical problem
F. Capability of handling green interior projects

15. WHY not BIM in Interior Design Process ?
 BIM is more than 3D modeler (Data embodied in ONE model)
 BIM is based on an architectural classification system, not layers
 BIM is parametric capability (Data synchronized instantly)
 BIM reduces overall project process & time consuming
 BIM can create material take off & cost estimate in early stage
 BIM has powerful 3D visualization ability
 BIM makes interior designer can involved & integrated with arch
BIM file from early stage not in the middle of project process
= SHIFTING INTERIOR DESIGN WORK FLOW TO NEXT LEVEL
