Abstract

The improvement of existing buildings had been argued as a major approach to attain sustainability in the built environment, especially in the developing countries. However, literature had shown that users’ requirement, which are hardly met in improved buildings, is a basis for attaining sustainable improvement. The research thus approached sustainable improvement of public office buildings through the lean thinking concept, which involves the application of muda to the typical improvement diagnosis technique for enhanced assessment of users’ requirement. The research methodology involved the quantitative method, using diagnostic Post Occupancy Evaluation (POE) as data acquiring tool from the Federal Secretariat complex, Bauchi in Nigeria, with confirmatory factor analysis carried out using Structural Equation Modelling (SEM), a statistical tool used to analyze the inter-relationships between perceived muda, job productivity and design features variables in the study area. Survey questionnaires related to the triple bottom line of sustainable development were distributed to all the 971 civil servants in the study area, from which 339 useable questionnaires were retrieved. The analyses were done using Satisfaction Indexes (SI) and Analysis of Moments Structures (AMOS) regressions, while the findings established that perceived muda is inherent in public office buildings, with highly significant inverse causal effects of -0.661 and -0.760 on job productivity and design features respectively; and strong effect sizes of 44% and 58% in explaining both their variances respectively. It further revealed that users require more improvement in facilities as compared to spatial plan and structure, while there is a direct and moderate correlation between job productivity and design features; implying that as design features are sustainably improved with emphasis on facilities, job productivity will consequently improve. The research concluded that lean thinking can enhance the assessment of users’ requirement in existing public office building improvement diagnosis in developing countries; but can however, not replace the technique since the end-users are not able to provide the technical details of professional expertise and equipment needed in a typical improvement diagnosis technique.
