Das, S (2009) Comprehensive maintainability scoring system (COMASS) for commercial buidings in tropical climate of Singapore. PhD thesis, National University of Singapore, Singapore.
Abstract
Dearth of holistic grading system to integrate design-construction-maintenance guidelines and their maintainability impacts causes prevalent and recurrent defects. Proposed COMASS is a decision-enhancement tool applicable for part or whole of a new or existing building to select the best strategy. Data was collected through casestudys, surveys and face-to-face interviews of facility managers. 'Defect Library' is analysis of causes and criticality of 319 types of observed defects for nine major building elements using FMECA. A total of 731 defect-mitigating checklist factors along with scoring logic constituted 'Maintainability Handbook'. Using objective and subjective parameters, AHP integrated building elements using 12 sets of relative weights for various location-height combinations. Values were coherent with expertsb subjective opinions. Predictive accuracy of COMASS was found satisfactory through operational validity and sensitivity testing via Monte-Carlo simulation for a hypothetical multi-tenant office tower at CBD. A user-friendly online application was also developed. The generic method can be applied for other building types or climates and aspires to improve the maintainability profile of buildings significantly.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
