Sustainability has become a wide-ranging term that can be applied to almost every facet of life on Earth, ranging from a local to a global scale and over various time periods. The existence of more than 70 different definitions for sustainability (Holmberg et al., 1992) highlighted its importance and illustrated the efforts made by different academic and practical disciplines to define and understand its implications to their fields. Continuous Improvement (CI) is a very critical tool in the construction industries today to enhance customer satisfaction, to become the cost leader and also to remain competitive in the global world today. The current study explored the sustainability of continuous improvement in the construction sector in the Tamale Metropolis. The study targeted thirty-nine (39) construction workers. The instrument for the data collection was developed by the researcher, preceded by a pilot study. The pilot study was initially conducted in similar construction industry with same project to ascertain its validity and reliability. The data for the study was basically from primary source in that closed-ended questionnaire was designed and distributed to stakeholders. Descriptive statistics was used to test the data. The study found that functional integration is one of the important components of sustainable continuous improvement. The study indicated that design for construction challenges is one major challenge on the project. More importantly, the study found that implementing standard operations, instructions and checklists and implementing continuous flow were the most significant mitigating strategies to the challenges of the project. The study recommended that project implementers Project implementers use Functional Integration as the main component in implementing sustainable continuous improvement by designing the project around processes, product and customers and also having Multifunctional teams to optimise processes and value streams to deliver product. Further, the study recommended strongly that Constructors especially, workers on the Office Complex Project have formal analysis of the mitigating strategies to the challenges associated with continuous improvement.
