Improving risk identification on large infrastructure projects
Ruijsscher, T. de (2016)
Due to government austerity, governmental agencies are downsizing and the contractors
in the construction industry are increasingly responsible for more phases and tasks within
construction projects. Not only have they become responsible for the construction phase
itself, but also for design, maintenance and in some cases even finance. Furthermore, they
are required to provide complete services, which means the combining of different
disciplines in a single contract. These increased responsibilities also lead to an increase in
risks for which the contractor is responsible. Together with the pressure on turnover in the
infrastructure sector specifically, these cause contractors to improve their project
management expertise and all relating processes. Recent examples in the industry
illustrate the need for a high level of expertise of risk management. These developments
led to the goal of VolkerInfra to improve their risk management expertise and knowledge.
The research is based around six case studies. These concern six large infrastructure
projects of VolkerInfra, of which two are still in construction and four have been recently
completed. This approach was chosen because of to the strong project focus of VolkerInfra.
To measure success on these projects, usually a set of objectives is developed that the
project hopes to accomplish. Part of these objectives are the traditional operational
objectives of cost, time and quality. Of these three, cost is the most obvious and consistent
measure of project success and therefore this measure is chosen as initial assessment
parameter for the effectiveness of risk management.
However, an initial review of the cases revealed that there is limited data available on the
cases. The data that is available on all cases however, is the amount of identified risks, in
both the tender phase and the execution phases of the cases. These revealed that most
risks are identified after tender, while ideally they should be identified during the tender
phase to prevent surprises when going down the project life-cycle. Due to the limited
available other data, a further analysis of cost data was only limited possible. Furthermore,
a literature revealed that there was limited attention for the risk identification part of the
risk management process. For these reasons it was decided to focus on risk identification.
This led to the following objective in the research: "Develop recommendations for the
further development of the risk identification process and identify and classify top risks on
VolkerInfra projects to enable generic oversight to assist in risk identification on future
VolkerInfra projects.”.
Interviews were held with the six risk managers of the six cases to determine their
preferred risk identification approaches. These interviews revealed that each risk manager
has their own preferred approach to risk identification and that this approach developed
little over time. It also revealed that there is no company guideline on how to perform risk
identification. The approaches of the risk managers were divided in the tender phase and
the execution phase. During the tender phase, personal interviews, brainstorm sessions
and work groups led by the risk manager were the preferred methods for risk identification.
During the execution phase, only the personal interviews were preferred, while few other
methods were applied.
The literature review also revealed that there are multiple other tools that can be developed
to help during the risk identification. These are mainly historic records and checklists, both
of which were little used by the risk managers. Historic records are a valuable source of
information for risk identification. These historic records are currently unavailable and
therefore the goal was to develop the starting point for a database of historic records. The focus lies on occurred risks for the starting point, as these are considered to contain the
most valuable information to enable reflective learning from these records. These are
however only available on three of the six cases.
To be able to maintain an overview of these records, a classification has been developed.
This classification consists of a number of criteria, each with a number of underlying
categories. Each risk is assigned a category per criterion. The classification will then enable
oversight over the projects of the most prevalent classes of risk and thus the identification
of the most important points of improvement. Due to the time consuming process of
categorizing risks, only the most important occurred risks have been classified. The top
fifteen (based on the calculated value, which is an estimate of the financial consequences)
occurred risks of the three available cases is classified, giving a total dataset of 45 risks.
The most important criteria are the phase identified, nature of the risk and the source of
origin criteria. The classification revealed that 27 of the 45 risks was identified after tender.
However, further analysis revealed that 15 of these 45 are due to an insufficient risk
identification process. The other 12 were attributable to unforeseen scope changes,
overarching risks that were identified sooner (so called container risks) and a force majeure
and therefore not culpable to a faulty risk identification process. Further it revealed that
most risks are of a technical nature, with process and managerial having a lot less risks in
the top fifteen occurred. The source of origin criterion revealed that there are a number of
risks present due to opportunistic behavior in the form of commercial decisions and a
number of risks occurred as a consequence of another risk occurring. Based upon this
research it can be concluded that there is a lack of guidelines for risk identification.
Furthermore, a lack of data prevents further analysis of the effectiveness of the risk
management process. There is also some ambiguity regarding the definition of certain
concepts relating to risk management.
Based upon this research, ten recommendations are being made to VolkerInfra to develop
their risk identification process. First of all it is recommended that more data is recorded
of risks, this data should at least consist of: the occurrence of the risk, cost data relating
to the risk and a classification in the following criteria: main- and sub-object, nature of the
risk and source of origin. When this data is recorded, this will allow for benchmarking of
future projects and the setting of goals for improvement. Furthermore, relevant concepts
and the exact purpose of risk management have to be clearly defined in order to prevent
confusion and differences of approaches between the different risk managers. Fourthly,
opportunism due to commercial decision should be prevented and be included as
opportunities and not as risks. Due to the revealed link between different occurring top
risks, a conditional probability class should be added to the RISMAN categories to define
this relation. Guidelines for the risk identification process are formulated in order to develop
and improve that process. This guideline makes use of all information gathered from the
literature and empirical research parts and proposes the following sequence: Start by
collecting all relevant documents and data, this includes tender documents, flowcharts and
breakdown structures. If the first recommendation is followed, more data is recorded on
the projects that can be used as historic records on future projects, which should be the
second step. Then a combination of identification methods should be applied to prevent
bias from either ones. This should be followed by a check for opportunism, check for
conditional probabilities and then a full risk assessment of the consequences and
probabilities. These can then be mutually compared to come to the final risk database for
tender. This is a structured approach that is recommended to VolkerInfra as development
of their risk identification process.
