Framework of the architectural Safety Design Assessment (ASDA) through integration of the Prevention through Design (PtD) concept for the affordable housing maintenance stage / Nor Syamimi Samsudin

Occupational Safety and Health (OSH) design for maintainability upkeep remains a prominent concern for Malaysia's housing industry. Although many studies have urged the implementation of Prevention through Design (PtD) as a proactive safety intervention throughout the design process to mitigate maintenance accidents, there has been a very little study that looks into the inclusion of PtD as part of design intervention and how it can provide an architectural view on OSH concerns. As of right now, neither a conceptual framework nor architectural design parameter on the essential safety design aspect for maintainability to attain this issue. Therefore, this research aims to develop a framework that aids in improving the workplace safety design aspect for maintainability, which may assist the architect during decision-making at the initial stage of the affordable housing project, focusing on adequate safety design during the maintenance stage. The research has three research objectives: i) to identify the attributes of architectural safety design criteria that substantially mitigate occupational accidents at the initial design stage of affordable housing maintenance work, ii) to formulate the relative importance score of the architectural safety design attributes to assist in the early architectural decision-making process, and iii) to develop an Architectural Safety Design Assessment (ASDA) framework that can demonstrate architectural design and preventive measures of workplace safety for maintenance work at the initial design stage of affordable housing projects. A mixed-method approach was utilised for this study. The ASDA framework was developed based on the analyses and results of the three rounds of the modified Delphi-AHP method.
