English Abstract

The nature of the construction industry is one of the riskiest nature among other industries, so most of researches focuses on how to manage these risks and the most important methods used to reduce or minimize their effects.

The aim of this research is to assess the risk factors that may exposed to the construction of building projects from contractor’s point of view.

Multi criteria decision making support models are built using Analytic Hierarchy Process (AHP).

Comparing the main risk categories and factors to get the most effective ones, which have the most negative impact on the construction projects, then identifying the optimum preventive actions toward these factors.

All these objectives are achieved through two surveyed questionnaires as well as semi-structured interviews conducted in Gaza Strip.

The target group was the first and second-class building contractor, so the questionnaires are distributed to 52 contracting company, as well as 10 semi-structured interviews are conducted with professional engineering experts.

After the analysis of the first questionnaire, It is been found that the financial failure of a contractor, unstable security circumstances (wars), the closure, the monopolizing of materials due to closure, increasing material prices, deterioration quality of work and the decrease of productivity are the most important risks occurring in the construction of building projects.

Another findings of the least effective risks, those risks can be predicted and thus can be prevented, most these risks are been categorized under the list of physical, logistics, design and the legal risks.

These groups are been omitted and the rest groups are adopted for the second questionnaire.

The findings of the second questionnaire shows that the best preventive response toward the riskiest factors is depending on the subjective judgment to produce a proper program, and the second alternative is referring to previous and ongoing similar projects for accurate program.

The third alternative that must be invoked after that is transferring or sharing risk to/with other parties, and the production of proper schedule by getting updated project information is the last alternative.

Based on these results, the study inveterate several recommendations, the most important that the contractor must have attention to perform risk assessment to the project that is intending to bid for, this inevitably would lead to reduce the risk effects in all phases of the project.

Another recommendation is to use the models in this research to help all parties in the decision-making procedure related to risk management.
