COST OVERRUN IN PAKISTANI CONSTRUCTION INDUSTRY
Abstract
1. The construction industry is dynamic in nature due to the increasing uncertainties in
technology, budgets, and development processes. Nowadays, building projects are becoming
much more complex and difficult. Cost is among the major considerations throughout the
project management life cycle and can be regarded as one of the most important parameters
of a project and the driving force of project success. Despite its proven importance it is not
uncommon to see a construction project failing to achieve its objectives within the specified
cost. Cost overrun is a very frequent phenomenon and is almost associated with nearly all
projects in the construction industry. This trend is more severe in developing countries where
these overruns sometimes exceed 100% of the anticipated cost of the project.
2. This study attempts to identify the major cost overrun factors in the construction sector
of Pakistan, which can serve as the way forward for future work in coping with these
overruns.
Introduction
3. Cost has its proven importance as the prime factor for project success. Most of the
significant factors affecting project costs are qualitative such as client priority on construction
time, contractors planning capability, procurement methods and market conditions including
the level of construction activity. A project otherwise completed may not be regarded as a
successful endeavor until and unless it satisfies the cost limitations applied to it. In spite of its
proven importance it is not uncommon to see a construction project failing to achieve its goal
within the specified cost. Cost overrun is a very frequent phenomenon and is almostassociated with all projects of construction industry. Cost overrun can be simply defined as
when the final cost of the project exceeds the original estimates. It is believed that
construction projects experience an increase in cost of about 33% on average. The trend is
more severe in developing countries where these overruns sometimes exceeds 100% of the
anticipated cost of the project. Low quality materials cause higher construction cost than
expected because of the loss of materials during construction.
4. In Pakistan, construction sector is an important sector. Although not working to its
fullest potential, it still is of prime interest to the country. Growth in this sector is critical for
growth in national income as it isamong the largest sectors that generates employment within
the country as well as a key indicator of the economy of Pakistan. As many other developing
country, Pakistan is facing also cost related issues among which cost overrun is quite
prominent. There are several factors that are responsible for these cost overruns. This paper
attempts to identify the major factors of cost overrun in construction sector of Pakistan and
can serve as the way forward for future work in coping with these overruns.
5. Objectives and Scope. The study has been conducted to identify the issues
involved in cost overruns in construction projects in Pakistan. In this regard certain factors
have been identified through the study and their importance and impacts have beendiscussed. In total twenty five (25) factors were short-listed to be made part of the survey
questionnaire and the survey was conducted with representatives from local Managerial
executives / general contracting firms. Furthermore, some recommendations and mitigation
measures have been suggested to strategically cope up with these factors. This study project has
four main objectives:
a. Assess the current state of Pakistan construction industry through quantitative
research with specific reference to the status of construction management
education, research and practice.
c. Devise a framework to standardize the construction industry practices for
achieving improved performance on cost, time, quality, productivity and safety.

d. Capacity building of academia, industry, owners and government in the area of
construction management so as to improve the overall efficiency and
productivity of the construction industry.
The general objectives were met through accomplishment of several specific tasks.
6. Research Tasks. The following research tasks were completed.
a. Define the project failure criteria
b. Identify the factors affecting construction project success
c. Develop structured questionnaire
d. Collect data
e. Analyze data
f. Develop guidelines for CSFs
7. Research Methodology. The methodology of the study is follows:
a. A thorough literature review was done and also the expert opinions from localsinvolved in the business were taken, through which a number of cost overrun
causes were identified in the local construction industry scenario.
b. Questionnaire consisting of two parts A and B was developed. In Part A
personal Information of the respondent was asked. Part B was aimed to obtain
information about causes of cost overrun in Pakistan construction industry, it
was asked to rate those initially identified twenty five (25) factors according to
their severity level on the given scale.
c. A survey was conducted through postal mail and personal interviews in which
respondents were asked to rank and score these factors according to their
experience. _______ x construction firms were approached for these surveysout of which ______________ responses were received with the response rate
of ____________%.
d. Assessment of feedback from questionnaire survey was made. Analysis is
discussed in detail in the following section, on the basis of which
recommendations to construction industry of Pakistan were made.
8. Cost Overrun Factor Analysis. From the initial analysis top ten factors of cost
overrun, on the basis of severity impact scoring received, were selected for the further in
depth analysis. It is evident that both internal and external aspects of business setting are
present as the prime contributors to cost overruns. Cost is affected by a large numbers of
factors because of the fact that construction is a multidisciplinary industry and its work involve
many parties such as the owner and various professionals, contractors and suppliers. For the
purpose of analysis the identified top ten cost Overrun factors have been arranged into three
broad categories as follows:-
a. Macro Economic Factors
(1) Fluctuation in prices of raw / manufactured materials
(2) Contractor-related factors
(3) Poor cash flow during construction
b. Management Factors(1) Poor project (site) management/ planning
(2) Slow decision making
(3) Lack of proper quality control
c. Business and Regulatory Environment
(1) Inappropriate government policies
(2) Lowest bidding procurement method
(3) Long period between design and time of bidding/tendering
(4) Cost estimation errors
9. Factors other than qualitative. We see numerous projects being completed
over and above the budget and schedule. Is this the result of incompetence on the part of the

estimators and schedulers? Unequivocally, the answer is No! Why, then, does it happen?
There are, of course, many factors affecting estimates and schedules, other than
contemplative and rational deliberation, measurement, and calculation, and they are as
follows:
a. Pressure from owners to minimize costs and schedules. This is not
inappropriate: where money and time are limited, people can be very innovative
and, conversely, where money and time are unrestricted, people have a
tendency to be profligate.
b. Intentionally tight project budgets and schedules. These are
designed to pressurize project management in hopes of minimizing project
costs and schedules, often accompanied by financial incentives for the
contractors. Assessing whether estimated costs and schedules are excessively
tight, can be determined by comparison with other similar projects and by
comparing the values with those in cost estimating handbooks.
c. Contractors that estimate and bid low are more likely to win work;
accordingly they are so inclined. Still, this does put them under pressure toachieve the accepted values.
d. Lack of knowledge or insufficient knowledge. If a project incorporates a
significant part or parts of it related to lack of knowledge, there is a tendency for
things to go awry.
10. The Three Blind Mice. Is there any way to judge the vulnerability of a project to
cost and schedule overrun and to quantify how much more it might cost and how much
longer it will take to complete? There certainly seems to be a relation between overruns and
the following factors, all of them related to lack of knowledge or insufficient knowledge, what
might be termed the three blind mice of projects:-a. Remoteness. Remoteness is certainly a factor in making a project
subject to cost and schedule overruns. When projects are in remote locations
the efficiency of logistics, the availability of services, and the efficiency of
construction come into play. It is difficult for estimators and schedulers to
properly assess these factors and include them in preparing cost estimates and
schedules, perhaps because they are not familiar with them. How much
allowance should be made for remoteness?
b. Unconventionality. Unconventionality is certainly a factor in cost and
schedule overruns. While incorporating new processes and methods is
sometimes essential to even make a project viable, it does increase
vulnerability. Of course, when new processes or methods are incorporated they
are generally well tested and well thought out, but, even so, they have a
tendency to go awry, often as a result of unexpected interactions with other
well-established processes and methods. We suggest adding 50 percent to
both cost and schedule in the most extreme circumstances.
c. Schedule. Overruns Schedule overruns are usually closely related to cost
overruns, but this is not always the case; it seems that schedule overruns occur
even where cost overruns do not occur. Schedules do not incorporate
contingencies, they are set to follow projected work sequences and equipmentdeliveries, and including extra time for possible upsets and delays is not
rational. But delays usually occur; if they are minor it is often possible to catch
up, usually by working extra time; but just as often the cumulative effect of
delays is such that it is not possible to catch up, and most projects exceed the
projected time by about 10 percent as a matter of course. Such delays,
unrelated to specific problems related in previous paragraphs, also add cost,
generally about one percent of the project total cost per month of delay.
11. Recommendations.
a. Macro Economic Factors.
(1) Control on prices may or may not be even under the control of
Government being a global issue, therefore, only counter measure what

we can ensure is the timely completion of project to avoid extended
inflations and recurring costs.
(2) Selection of appropriate contractor and half the job is done. The main
contractor and subcontractors start their main duties when the project
reaches the construction stage. The variables include contractor
experience, site management, supervision and involvement of
subcontracting, contractors cash flow, effectiveness of cost control
system, and speed of information flow.
(3) Complete economical road map must be prepared on the basis of factual
availability / expected cash flow and not on wishful thinking.
b. Management Factors. Project management action is a key for project
success and by using the management tools, the project managers should be
able to plan and execute their construction projects to maximize the projects
chances of success. The variables in project management include adequate
communication, control mechanisms, feedback capabilities, troubleshooting,
coordination effectiveness, decision making effectiveness, monitoring, projectorganization structure, plan and schedule followed, and related previous
management experience.
c. Buisiness and Regulatory Environment. Various researchers support
environment as a factor affecting the project success. Environment can be
described as all external influences on the construction process, including
social, political, and technical systems. The attributes used to measure this
factor are economic environment, social environment, political environment,
physical environment, industrial relation environment, and level of technology
advanced.
6. Conclusion. Results indicated that the majority of cost overrun factors (88%)
lie in medium severity impact zone (with a rating between 5 to 7.5 out of 10), signifying that
major attention needs to be given to these factors as they collectively cause considerable
cost overrun. It is evident from the findings that both internal and external aspects of business
setting are present as the prime contributors to cost overruns. The top ten cost overrun
factors found were: fluctuation in prices of raw materials, unstable cost of manufactured
materials, high cost of machineries, lowest bidding procurement procedures, poor project
(site) 500 management/ poor cost control, delays between design and procurement phases,
incorrect/ inappropriate methods of cost estimation, additional work, improper planning, and
unsupportive government policies. An additional finding is that medium sized construction
firms experience a greater percentage of cost overruns owing to their tendency to assume
greater risk for the purpose of business development. Major recommendations include:
stabilizing cost of materials, increasing supply of materials and machinery, more involved
cost estimation processes, vigilant project planning, close observance and documentation of
cost variation trends in the sector and the country, adoption of alternative procurement
strategies such as design-build contracts, and best value procurement.
