The construction industry is prone to unethical practices as reported in construction literature worldwide. There is a need for construction organizations to put in place methods for detecting and combating wrongdoings. The purpose of the study was to develop a method for assessing the presence of integrity systems in construction organizations. Interviews, a questionnaire survey and three case studies were used to collect data. The study established the need for the development of a method for assessing the presence of integrity systems in construction organizations. The framework developed to achieve this is presented. The study established that integrity systems in construction organizations that were sampled in Zambia were moderately developed. The framework to assess the presence of integrity systems reported in this paper could be a useful tool in evaluating ethical compliance in construction organizations. It could be used as a tool for self-assessment by construction organizations. Self-assessment can bring to management's attention areas that require improvement.
