“…According to Brooks [27], facility management (FM) is an integrated approach for an organization to operate, maintain, improve and adapt its building infrastructure in a way that the primary objectives of the organization, occupants, owners and/or end-user are supported. The operation & maintenance (O&M) stage is typically where the large portion of the whole lifecycle cost is incurred and the stage represents a signi cant opportunity for cost e ciencies [2], [6], [31].…”

Digitization of a building infrastructure requires the creation of big data that needs to be modelled and integrated into digital platforms from initial/design phase to operation & maintenance phases to serve as a single source of reliable information. This insufficient integration and/or transition of building information modelling (BIM) into asset management has posed challenges in the operation & maintenance performance. Thus, it is compulsory for owners and end-users to invest in creating digital data for built assets in taking advantage of incorporating building information modelling (BIM) into operational functions. Nevertheless, creating a BIM-enabled asset management and development of a big data repository is costly, time-consuming and requires expertise that may not be achievable without specific targets to make data-driven decisions. The aim of this study is to prioritize the information requirements using building improvement/adaptation, maintenance/ preservation and deconstruction/disassembling as strategic decisions in built asset management. The data for the pairwise comparisons among criteria, strategic decisions, and information requirements was collected from 11 expert’s using AHP pairwise questionnaire. The collected data was transformed into triangular fuzzy logic to overcome the lack of precision and uncertainties of human thought process. A fuzzy-AHP approach is utilized to analyze the collected data. The degree of importance of all forms of information requirement is determined in relation to the strategic decisions. The results showed that all forms of information requirements varies with the type of strategic decision. The results of the present study can help built asset owners and their representatives to define information need based on the decision type using criteria for efficient built asset management.

“…This allows for nuanced interpretations and the adept handling of intricate situations. To deal with the uncertainties and vagueness of experts in responding to AHP questionnaire, triangular fuzzy set is used in the present study to transform the crisp values from to triangular fuzzy membership function [31], [68], [69].…”
