1. Introduction
Construction sector consists of a group of activities, which are related to engineering construction works of
various kinds. This sector is characterized by a close relationship with all other economic sectors. This is why it
is an important and reliable indication to movement of the national economy and its trends. However, there are
many risks that are faced by the construction projects. These risks may negatively affect the on time, cost and
quality of the project. These risks might be inherent or apparent, or interact with each other. In addition to that, it
is hard to avoid these risks or predict them with a high degree of accuracy, or their effect on the project. These
risks relate to the work environment, economic policies, political events, social aspects, climate environment,
government laws and regulations (Migdadi, 2016; Newton, 2015). Based on the aforementioned the study
problem is represented by the following questions:
1) What is the nature of construction projects management?
2) What is the nature of risks in construction projects sector?
3) What is the nature of the process of risk management of construction projects?
This study aims at achieving the following objectives:
1) Analyzing the nature of construction project in terms of concept, topics, processes, and life cycle of
construction project management,
2) Analyzing the nature of construction projects risks in terms, concept, and types,

3) Analyzing the mechanism of risk management of construction projects in terms of its concept, risk
management process, risk identification tools, techniques for qualitative analysis of risk, techniques for
quantitative analysis of risk, and risk response strategies.
The study has three main hypotheses which are represented as follows:
HA1: There is a special nature of the construction projects.
HA2: There is a special nature of the construction projects risks.
HA3: There is a mechanism for analyzing risks in construction projects. Through this mechanism, the negative
effect of these risks on the construction project's objectives is reduced.
The study adopted the quantitative method by which library survey is conducted, and study of theoretical studies
and research in order to crystallize the principles and theoretical bases that the theoretical framework of this
study is based on.
The significance of this study lies in two main levels:
The first level: The theoretical level
The theoretical significance of this study lies in the academic field as it provides a reference in the construction
research field, where this study provides theoretical frameworks for the nature of construction projects, the
nature of construction sector risks, and the nature of risk management of construction sector, which will help
researchers, academics, and experts in this sector to generate ideas, and concepts to conduct different studies and
research in this sector in terms of methodology, targeted group, and countries in addition to the possibility of
linking these research with different fields and different cognitive sciences, which will lead to reduce the gap in
the construction search field.
The second level: The practical level
As far as the practical base is concerned, this study provides a clear conception of the risks that this sector is
exposed to, how these risks are qualitatively and quantitatively analyzed as well as risk identification tools, and
risks response strategies, which will help decision-makers in this sector learn about the nature of these risks in all
their aspects in a way that helps generate ideas through which plans and strategies are formulated, which are
based on principles, standards, and correct, clear, and scientific methodology, that is compatible with the
variables and international standards, which will help reduce the negative effect of risks in a way that contributes
to the success of projects of this sector.
2. Literature Review
2.1 Nature of the Construction Projects
2.1.1 Concept of Construction Projects Management
According to modern management concepts, construction projects management is defined as an effective
management which plans and controls the project's activities. It also schedules its activities properly, and takes
the necessary measures to speed up performing activities to fulfill the obligation of accomplishing the project in
time. The role of management in construction projects is not only limited to a specific phase of project
performance phases but also begins as the project starts, and does not end until the project ends. Thus, the
management has to identify all requirements for each one of the activities as well as the simultaneous activities,
which are performed together at the same time. The chokepoints and the potential components should also be
identified to deal with them or avoid them. The time line for achieving each activity and its beginning and end
date should also be identified with a coordinated distribution of material and human resources. One of the duties
of construction projects management is to analyze deviations which occur during the preparation of control
reports, and then to take the necessary corrective measures to correct the situation (Gabel, 2013). The concept of
construction projects management is based on several topics as indicated by Loader (2006), (Musa et al., 2012)
and is represented as follows:
The first topic: Scope
The construction project has known objectives, and the scope in the project is identified during the life cycle of
the project.
The second topic: change
There are many predictions that a change would occur in the construction project, which requires performing the
processes that tend to control this change and reduce the negative effects resultant from it.

appropriate strategies to engage them in decision-making, and perform the projects effectively.
2.1.3 The Construction Project's Life Cycle
The project's life cycle is divided into basic phases, which are represented by beginning, planning, execution,
following up, controlling, and closing. It comprises the course of the construction project from beginning to end,
and life cycle of projects management as referred to by (Nepal, 2014; Pieplow, 2012; Macro, 2014) and is
represented as follows:
The first phase: beginning of project construction
It includes the process of identifying the nature of construction project and its range through understanding the
environment work, and ensuring the control of all project requirements, and preparation process (beginning
phase) includes the following steps:
1) Analyzing the construction project requirements in a standard way -in other words dealing digitally with the
project parts including the time, labor, raw materials, and financing.
2) Reviewing the current operation capacities as an initial phase of assessing the available potentials of the
company to perform the construction project.
3) Financial analysis of input and output, which includes the average spending in the construction project.
4) Analytical assessment to distribute tasks in a more efficient way between elements of work team in the
construction project.
5) Creation of a detailed map of the work phases in terms of tasks, cost, delivery schedules, and expiration of
the project.
The second phase: construction project planning
This phase includes project planning to guarantee compatibility between the elements of time, cost, and
resources and the average work to be done, while assessing accepted risk factors. This phase comprises the
following steps:
1) Identifying a strategy and proper planning model to carry out the project as a serial plan.
2) Development of dealing with available resources in the most efficient way.
3) Selecting the appropriate planning and designing team.
4) Sorting out priorities and delivery phases, and identifying the track of operational activities in the course of
construction project.
5) Assessing the required resources and the estimated budget for all the operational activities in the course of
project.
6) Developing work schedule in a way that matches with requirements of carrying out the project.
7) Planning to deal with potential risk factors in the course of the project.
8) Obtaining the official approvals to start work.
9) Ensuring the smoothness of communication between project coordinators. It is preferred that there is a
conceptual model of the construction project and its processes so that it helps in identifying what is required to
achieve and delivering it in the required precision.
The third phase: carrying out the construction project
After obtaining an approval for an action plan, the action plan is translated into execution. The project manager's
task in this phase is to keep the action plan on the right track, and to communicate with all members of the
project to provide necessary guidance, and to control work quality and spending, and to be on the right track in
terms of assets, resources and budget tools.
The fourth phase: Following up the construction project
It includes the control process of execution phases, its levels, and initial output. This phase includes the
following activities:
1) Phasic measurement: assessment of cost, effort, potentials, and how compatible they are with the drawn-up
plan to reach the objectives of the construction project.
2) Applying practices which correct the work track in case they were needed.
18
emr.ccsenet.org Engineering Management Research Vol. 9 No. 1; 2020
3) Controlling factors that lead to departing from the complete application of work parts, particularly in
multi-phases projects, where controlling and checking the source of feedback is in the advanced phases to correct
any tracks incompatible with what is required to do.
The fifth phase: termination/closing
This phase represents the delivery phase and includes the following activities:
1) Termination of the construction project by terminating all activities included by the project with
documentation of executive phases as a future work and information reference.
2) Termination of contracts which include reviewing and accrediting contracts at the expiration of project by
all parties participating in the construction project.
2.2 Nature of Construction Projects Risks
2.2.1 Concept of Construction Projects Risks
Risk in construction projects can be defined as an uncertain event or case from which a positive or negative
effect on the construction project result (Qasem, 2012). (Raftery, 2003) defines it as deviation from the wanted,
expected or hoped result of the construction project. From the viewpoint of (Simu, 2006), it is uncertainty that is
related to the occurrence of some loss. Furthermore, (Tetteh, 2014) defines it as the possibility of the occurrence
of loss, damage, negative consequences in the ongoing construction project. Risk in construction projects include
a cause and a resultant effect, for example, the cause is the qualified, limited, and available workforce of the
project, or this work force is unsuited to the tasks that are assigned to it. There fore, the result or consequence
will be visible in the additional cost, or fault in scheduling work, and the length of execution time. There are
known risks, which have been diagnosed and became possible to plan in order for them to be controlled. On the
contrary, unknown risks cannot be managed. However, the project managers can deal with them through
implementing general contingency plans, which are based on the past acquired experience through carrying out
former projects. There are risks which are considered as opportunities, and these are risks that threaten the
project's success, but they are accepted when a budget is set for them in return of what will result from them
(Wallo, 2015; Varsh et al., 2015).
Types of risks in construction projects
In consequence of environmental factors, and what follows them from technological developments, which added
the capacity of change in construction projects ,this made construction projects exposed to various types of risks,
some of them are related to the work environment, some are related to economic policies, and some are related to
social aspects. These risks might be changeable or fixed. Here is an explanation of the risks of construction
project as indicated by (Akab, 2009).
First: legal risks
It means a lack of or non-existence of legal vision for requirements and potential modifications in the following
aspects:
• Safety terms.
• Regulations related to environment and urban planning.
• Noise.
• Purchase of properties.
• Submitting tenders.
• Exemptions and forgiveness.
• Procedures which are related to public places and regional planning.
The possibility of bringing lawsuits, which is represented by the following:
- Lawsuits by the beneficiaries as a consequence of mistakes in performance or a fault in the terms agreed
upon in the contract documents.
- Lawsuits by the municipality due to the failure to fulfill agreements, or damages to the surrounding areas of
the project.
- Lawsuits by neighboring residents due to damages to their homes or businesses.
- Mistakes committed by contractors or projects executors in connection with legal procedures.
19
emr.ccsenet.org Engineering Management Research Vol. 9 No. 1; 2020
- Mistakes committed by projects executors in relation with sticking with regulations during carrying out the
project.
Second: organizational risks
It means modifications in the program of project requirements as a result of the following:
• A change in defining or identifying the project.
• Non-existence of clear procedures for the project.
• Special procedures of the potential modifications, planning, costs assessment, and others.
• Procedures of accomplishing the project, and accepting it by the beneficiary.
• Administrative procedures.
• Procedures of submitting and granting tenders.
• Rewards procedures.
• A lack clarity related to special procedures of requirements, which are laid down by customer, manager,
municipality, and city.
• Failure to agree with different parties, which are related to the project.
• A lack or non-existence of good communications (whether internal or external) or non-completion of
communications plan.
• Nonexistence of a clear plan for quality.
• No clarity of the project's limits.
• No internal coordination between the secondary projects in the total project.
• Not taking other projects into consideration whether partially or totally.
• A lack of specialized human resources of a specific part of the project due to issues in project's organization,
taking in some individuals who have rare specialization, or making modifications to the project's cadres.
• A delay in requiring materials that the project needs.
• No precision or non-completion of different time assessments of project's parts.
• Non-completion or not taking interest in special contractual documents of the project.
Third: technical risks
• Incorrect assessment of the required technology, building ways, or project's phases.
• Modifications to design, ways, building, and execution.
• Extra work to link current achievement with a former one.
• Adopting creative methods or new work ways of execution.
• Design modifications that made during execution.
• Unwise assessment of the quantities of necessary materials to carry out the project.
• Disappointing performance by contractors whether executors or designers.
• No availability of required materials.
• Mistakes in execution.
Fourth: Zoning risks
• The presence of obstacles for work in the execution place.
• There are artifacts or what indicates that the area is archeological.
• There are pipes, and cables related to sewerage services, and others.
• Not providing an appropriate climate for execution, such as snowfall periods, or storms that last long.
• There is pollution in the area, which leads to the complication of the execution process.
• The quality of the land is not appropriate in terms of its ability to withstand constructions.
• Insufficient considerations with regard to vegetation resources in the place of project execution.

It is a process to identify the way through which activities of project risk management are applied. The
significance of planning lies in providing the resources, time, and establishing rules for risk management
activities.
The second phase: risk identification
This phase aims at discovering and recognizing all potential risks that the project is facing .These risks might
threaten the project's objectives totally or partially (Sonmez, 2002). Risks are identified through the following
tools as indicated by (Rejeedh, 2006; Abdullah &Ahmad, 2018; Williams, 2008):
1) Personal interview: It is a process of investigating facts through information gathering technique either face
to face or by telephone. This is done with experts or participants in the project, interested parties, and material
experts. Its aim is to identify risks and to recognize them.
2) Checklist analysis: Risks are recognized depending on the information and historical knowledge, which has
been acquired from former similar projects, ther sources and information. It is a part of procedures of quality
insurance documents of the organization. The minimum level of risks segmentation structure can be used as a
risk checklist. The team should make sure of discovering the elements that do not appear in the check-list. These
elements should also undergo review during project closing to make use of them in future projects.
3) Questionnaire: It is a group of miscellaneous questions, which are related to each other in a way that
achieves the project's objectives. When designing a questionnaire, the following has to be taken into
consideration:
- Identifying the required objectives of preparing the questionnaire in the light of the construction project's
objectives, and information that are required to collect.
- Translation objectives into a serious of questions and inquires.
- Selection of the questionnaire's questions and trying them on a specific group of individuals, who are
experienced in the construction sector to give their opinion about quality of questionnaire in terms of
understanding, comprehension, and significance.
4) Brainstorming technique: It is a process to generate ideas and solutions through a collective debate about
activities related to buildings works and engineering constructions of various kinds, the risks that building and
construction projects are facing, and the effect of risks on (time, cost, and quality of the project). Brainstorming
in the construction section can include management staff, controllers, execution engineers, suppliers, and
essential parties of the project.
5) Delphi technique: It is one of the most important techniques, which are used to look into the project's future,
to draw up policies, strategies, and alternatives for future perceptions of the risks that the construction sector
could face. A carefully designing program is used in this technique, and it has several questionnaires, which will
be given to experts in this sector while continuing to study them and getting a clearer picture of the project's
future.
The third phase: risks analysis
Two methods of analysis will be used in this phase, and they are represented as follows:
First: qualitative analysis
It is the study and analysis of size and the extension of the effect of the potential risk on the project's objectives.
In other words, risks are ordered according to how effective they are in the project's objectives (Schwalbe, 2007).
The following tools are used in the process of qualitative risk analysis as indicated by (Schwalbe, 2012; Wallo,
2015; Zandhuis, 2013):
1) Probability and impact assessment: It deals with assessing risks probability in addition to the probable
impact on the project's objectives, which are represented by time schedule, cost, quality along with negative
impacts of modifications and positive impacts of opportunities. The probability and impact of each risk, which is
recognized and identified is assessed.
2) Cause and effect diagram: It is a tool that provides a methodological way to look into the causes
contributing to the occurrence of risks, which are represented by fishbone diagram. Cause and effect diagram is
known as (Ishikawa diagram). It is a diagram that represents a module to display the associations between events
(its effects) and many causes for them, where it explains the main problem that has to be solved in the head of
the fishbone diagram and explains the causes in the bones, and branch to eventually reach secondary causes,
where it graphically explains the relationship between the effect and all factors that could affect this result.
22
emr.ccsenet.org Engineering Management Research Vol. 9 No. 1; 2020
3) Probability and impact matrix: It is a tool that is used by the project's team to help identify the probabilities
of risks occurrence, and the impact resultant from the occurrence of these risks, and how impactful they are on
the project's objectives, which help the project's team prepare a detailed plan to respond to risks of high
significance or priority. Depending on this matrix, risks are divided into four types:
a) First type: Risks with low probability and low effect, which are often ignored.
b) Second type: Risks with high probability and low impact, which can be dealt with during carrying out the
project.
c) Third type: Risks with low probability and high effect, which are highly significant risks. In case they
happen, a contingency plan has to be made.
d) Fourth type: Risks with high probability and high effect, which have a high priority. These risks have to be
paid careful attention by the project's team.
Second: quantitative analysis
It is providing a calculated quantitative description of the risk on the basis of probability of events and
consequences resultant from the risk in a cash value or another value (AL-Sosi et al., 2017). The quantitative
analysis has several methods, which are illustrated in the form (1-2)
source: (AL-Sosi et al ,2017), risk assessment in construction projects inMisrata, first conference of industrial
technique, Misrata university, Libya.
The fourth phase: planning the response to risks
It is the process of laying down options and procedures on the purpose of improving opportunities and reducing
risks that threaten the project. It includes identifying and appointing one person or more who takes the
responsibility for each response that has been agreed upon and then finance it (Ewelina, 2011). The strategies for
response to risk are represented, as indicated by (Simu, 2006), as follows:
First: strategies for response to negative risks
1) Avoidance strategy: It is avoiding risks by changing the project management plan to completely eliminate
threats through identifying time schedule, changing the strategy, or reducing the scope.
2) Transfer strategy: It means transferring some or all negative risks to a third party
3) Reduction strategy: This means reducing the risk effect so that it would be within the accepted limits.
4) Acceptance strategy: This means drawing up a contingency plan and dealing with the reserves of the
contingency plan to tackle the risks.
Second: strategies for positive risks
23
emr.ccsenet.org Engineering Management Research Vol. 9 No. 1; 2020
1) Exploit strategy: seizing the opportunity, and taking advantage of it, such as time reduction, or cost
reduction.
2) Sharing strategy: engaging a third party to grasp the opportunity and achieve the project's objectives.
3) Improvement strategy: increasing the probability of seizing opportunity such as increasing resources of one
of the activities so that it is performed early.
4) Acceptance strategy: getting ready to make advantage of an opportunity in case it occurs.
5) Emergent response strategy: some responses are prepared, i.e. they are not used except if events, which are
previously defined happened.
The fifth phase: risks control and check
It is the process in which risks that appear lately are identified, analyzed, or planned while following up known
risks, and risks listed in control list, and reanalyzing the ongoing risks, following up conditions that operate
contingency plans, following up remaining risks, reviewing the execution of risk responses, and assessing its
effectiveness at the same time.
3. Conclusions and Study Recommendations
3.1 Study Conclusions
The summary concluded from the study lies in the theoretical study of construction projects' risks. Building and
construction projects are considered to be of a special nature. One of its most important aspects is the length of
time, which leads to a change in circumstances since there are many phases of the construction project's life
cycle, starting from project beginning phase, to planning phase, execution phase, following up phase, and ending
with closing phase. Therefore, it contains many risks, which are related to different factors, such as legal,
organizational, technical, zoning, financial, social and political ones. A negative effect on the desired, expected,
and hoped result stems from these risks. Risk management in construction project takes the responsibility for
planning, organizing, guiding, and controlling risks to reduce and control the negative effects resultant from
them. The process of management of project risk analysis includes many phases. The first phase is planning
through which a way to apply construction projects risk management is identified. The second phase is risk
identification, which aims to discover and recognize all the potential risks that the construction project is
exposed to through the following tools: personal interview, checklist analysis, questionnaire, brainstorming
technique, and Delphitechnique. The third is a phase in which two methods of risk analysis are used. The first
method is the qualitative risk analysis, which aims at studying the range of effect through using the following
tools: probability and impact assessment, cause and effect diagram, probability and impact matrix, whereas the
second is the quantitative analysis, which aims to provide a calculated quantitative description of the risk by
using the following tools: interviews, sensitivity analysis, Monte Carlo simulation, events diagram, fault diagram,
and probability distributions. The fourth phase is planning a response to risks, and it aims at drawing up
strategies for risk. These strategies are divided into two groups: The first is strategies for response to negative
risks [avoidance strategy, transfer strategy, reduction strategy, and acceptance strategy]. The second group is
strategies for response to positive risks [exploit strategy, sharing strategy, improvement strategy, acceptance
strategy, and emergent response strategy]. The fifth phase is risks control and check, and it aims to follow up and
analyze recent risks.
3.2 Recommendations of the Study
Depending on the conclusions, the study recommends the following:
i.First main recommendation:
• Processes of assessing the efficiency of construction companies should be carried out by a qualified group,
which is capable of studying bases and required conditions in the construction companies. The study
recommends the use of the following basic and secondary standards in the assessment process:
1. Financial standardsecondary standards:
a) Current bank accounts.
b) Continuity of current accounts without interruption.
c) Cash liquidity.
d) A Detailed account of movable and immovable assets.
2. Company's experience and reputation standard secondary standards:

• Studying types of contracts and contract expressions thoroughly to identify risks that each party bears in the
construction project according to the specific contract to transfer risks to the party that is more capable of
managing it in a better way.
