Exploring perceptual mapping technique as an innovative method of representing construction cost information

Effective representation of cost information is crucial for decision-making. While traditional methods like Bills of Quantities provide essential details, their format can pose challenges for swift interpretation and comparison. This study explores perceptual mapping as an innovative complementary tool to enhance the representation of construction cost information. Adopting a qualitative methodology, data were gathered via semi-structured interviews with 16 experienced professionals comprising clients, Architects, Quantity Surveyors, Engineers in the Sri Lankan construction industry. Thematic analysis identified key insights into the applicability and benefits of perceptual mapping. The findings indicate that perceptual maps, when used in conjunction with detailed reports, significantly enhance cost data visualisation, facilitating quicker comparisons and improving decision-making efficiency. Participants recognised their value in overcoming the usability limitations of conventional formats. The study concludes that perceptual maps offer a powerful enhancement to traditional documentation by providing a clear comparative overview. This provides a clear comparative overview with notable implications for practical decision support and the theoretical understanding of information visualisation in the sector, especially when integrated with traditional documentation
