3. PROBLEM STATEMENT
 Urbanization will add 2.5 billion people to
urban populations by 2050, and
consequently 66% of the world’s
population will inhabit urban centres
(United Nations).
 Building tall is a viable solution to
creating urban space in areas where
there exists concentrated population,
scarcity of land, and high land costs.

4. PROBLEM STATEMENT
 Mega structures are subject to
underperformance issues such as time
overruns and cost overruns resulting into
delays.

5. In 2014, the Council of Tall Buildings and Urban Habitat (CTBUH) published an article
highlighting the growing rate of delay in tall building projects.
PROBLEM STATEMENT

6. OBJECTIVE OF THE STUDY
Understanding
the causes of
delay could
minimize and
control delays
To determine and rank the main causes of
construction delays in tall building projects

7. CAUSES OF CONSTRUCTION DELAY
36 CAUSES OF DELAY SELECTED AND GROUPED IN 9 CATEGORIES

8. QUESTIONNAIRE SURVEY RESPONDENTS

9. SURVEY RESULTS

10. SURVEY RESULTS

11.  Tall buildings are risky projects subject to increasing delay occurrences.
 The top three causes of delay in tall buildings include
 “client’s cash flow problems/delays in contractor’s payment”,
 “contractor’s financial difficulties”, and
 “poor site organization and coordination between various parties”.
 Delay causes such as “civil disturbances/hostile political conditions” and “labor
disputes and strikes” were perceived as relatively insignificant in the GCC countries.
 “Unexpected foundation conditions encountered in the field” was considered as an
unlikely cause of delay in tall building projects, as soil and foundation investigations
are considered critical aspects of tall building projects.
SUMMARY OF CONCLUSIONS

12.  Further research will seek to:
 Develop delay mitigation measures/strategies for tall buildings
 Develop delay risk management framework for tall buildings
 Adopt modern technology such as machine learning to learn from historical
data
 Models for estimating the cost and duration of tall building projects
 Models for forecasting delay in tall building projects
 Models for predicting the risk of delay in tall building projects
Etc.
