WHAT IS A CASE STUDY?

• A Qualitative Research Method for collecting information

• Case studies reveal stories and inside information about organizations, firms,

• These stories should include an in-depth analysis of the situtationabout organizations, firms,

processes, events, projects, etc.

COMMON CHARACTERISTICS OF CASE STUDIES

• Telling stories behind a particular result and what happened to bring it about

• Highlighting a project’s success, failure and characteristics making it special

• Bringing attention to a particular challenge or difficulty of a project

• Describing • What happened• When• To whom• With what consequences

WHEN SHOULD YOU USE A CASE STUDY RESEARCH METHOD?

• When there is a unique and interesting story to be told

• Unlike many other researchmethods, it includes the context and shows a more complete picture of what

complete picture of what happened and why

• Because of its detailed approach it is also used to complement other researh methods


ADVANTAGES & LIMITATIONS OF A CASE STUDY

• ADVANTAGES

– Provides more detailed information than other research methods (use open-ended questions)

• LIMITATIONS

– Difficulty of keeping the attention of a reader

– Considered less rigorous than ended questions)

– Presents data from multiple resources:

• Surveys

• Interviews

• Literature Review

5

– Considered less rigorous than other research methods

– Risk of bias

– Not generalizable


PROCESS OF CONDUCTING A CASE STUDY

• One of the top three companies in the airport facility management services in the world.

• They serve 370,000 flights and 41 million passengers annually.

BIM CASE STUDY 1. TAV HOLDING

• This case study examinestheir domestic terminal renovation project in Istanbul Atatuk Airport. The project covers 60,000 m2 project area and required a 70 million dollar investment. Istanbul Ataturk Airport


• The face of airport terminal building was completely modernized. The project received several international awards.

• The building project was prepared by the architectural


prepared by the architectural division of TAV.

• It was modelled in a BIM software. Using BIM model they manage to offer initial cost estimates for facility management services.

The 3D BIM Model of the Terminal

• BIM helped the firm for better design documentation, data integration and ease of updating


• The firm connected the BIM model with its facility management software called TAV Earth.

• With BIM they were able to coordinate model based on


coordinate model based on zonings.

• 3D zone information helped them also help make calculation that was difficult in the past.

• Architectural project was design elsewhere and sent in DWG format. ENKA is expected to produce a 3D BIM model that incorporates structural and mechanical projects.


• The firm constituted three project team, each responsible for one aspect of the process.

• The control mechanism and staff hierarchy was set for worksharing.

A view from the architecture

department of ENKA

• The building was divided into subpartsand a work sequence was established.


• BIM provides the precision needed in construction.

• The three dimensional coordination between the architectural, structural and mechanical solutions is very vital.

• The firm does not advocate the single BIM model for all tasks.

• They believe that 2D CAD drawings are still valid to be used in construction site.

A view from the architecture

department of ENKA

• This project had been a unique experience for the firm to reconsider their corporate standards.


• Arup is a multidisciplinary organization with many offices all around the world.

• Arup has two offices in Turkey: Istanbul and Ankara. These offices prepare construction
