-Facilities management (FM) has a significant growth since last two decades as a new and exciting profession that embraces many essential parts of the built environment. Emphasis on early involvement of FM in the design stage to deliver of an efficient building; which is easy and cost-effective to maintain for the occupants. Present days, maintainability turn into foremost concern and unprecedented challenges for the project team as building projects are getting much more complex and difficult. However, lack of considering FM at early design phase has become a potential issue to increase the operation and maintenance budget, premature aging and dilapidation. Thus, this paper explores the consideration of direct involvement of FM knowledge and experience in early design is found useful for the improvement of cost effectiveness in long term perspective, and subsequently the aim of this paper to investigate the impact of design issues towards easily-maintainable building projects at post-occupancy stage and providing the actual avenues to integrate FM in design development process. Therefore, a critical analysis of the literature has been carried out to identify the potential errors of design at post occupancy stage. The paper critically analyses the current approach of building design; and explore the contributions of FM knowledge during the design phase. Based on the study of literature, it has been established that majority of the maintenance issues at using stage is design originated problems; mainly architectural, structural, mechanical, HVAC, and plumbing and sanitary. The involvement of the FM knowledge and experience at design process will contribute to reduce major repairs and alterations in the lifespan of the building.Keyword -Facilities Management, Cost Parameters, Effectiveness, Design Process I. INTRODUCTION A holistic view of the topic facilities management (FM) has gradually developed as a new career over the past 15-20 years everywhere in the global and evolved into construction discipline since late 1980s [1]. It seems at reaching higher facility that is straightforward to run, maintain and manage. This new topic attempt to represent an elevated attention of the significance of the building operation and maintenance. This is avital part inside FM however the scope has emerged as broader and includes use of buildings in both the short and long term. FM is observed on the pre-operations level to peer how early involvement can create effective operations, reduce maintenance cost, end customers pleasure whilst also presenting higher facility that is good-looking and end user friendly. "FM at the design stage will add value to the facility by ensuring less "rework", emphasising value for money, efficient control of the team work". As a result, FM decisions in the early design stages of building projects are very important for enjoying long life better services in cost effective way. Numerous studies have attempted to explain that the early involvement of FM all through the design development a...
