Construction supply chains encounter a number of problems that can be the result of various disruptions within the construction supply chain flow. The flows within the construction supply chain are as follows: material, labour, equipment, information (client related) and management information flows (main contractor related). This research is debatably one of the first endeavours to quantify the construction supply chain flows impact on construction projects performance, on residential housing construction projects in Jordan in terms of time delays and to what extent it may affect project performance. Jordan differs from other countries in the middle east in terms of its culture, political situation and social fabric. The main aim of this research is to critically analyse the effect supply chain management has on the performance of construction projects. The adopted research methods incorporated preliminary investigation, main survey and simulation scenarios development. The preliminary investigation was conducted through regular site visits to two residential housing projects situated in Amman, Jordan over a two-month period. The main survey was conducted in order to highlight the problems faced by the construction industry regarding supply chain flows. The data gathered from the main survey were used in developing the simulation scenarios. The simulation scenarios were developed on a Critical Path Method (CPM) network of a residential housing project using Microsoft project2007 and the main survey data were incorporated by applying the highest pessimistic value of each flow element to the related activity’s duration. The results revealed that problems in the information flow within the main contractor’s company (management flow) caused the greatest impact on the project with a delay of 302 days. Labour flow ranked second with 125 days, followed by material flow with 69 days, information flow (client related) with 9 days and equipment 3 days. The findings of this research highlighted the status of the construction supply chain in Jordan, quantified the impact of construction supply chain flows on residential housing projects performance in time, provided possible solutions and corrective actions to overcome issues within the construction supply chain and proposed guidelines to integrate supply chain management in the Jordanian construction industry starting with a shift from the traditional contractual framework, then the integration of organisational processes regarding all participants together with long term commitment and trust. The integration would benefit the client and the contractor regarding the overall delivery of the final project but moreover, increased profit margins, decreased aggravation and stress.
