This study examined the influence of knowledge sharing and collaboration on the performance of estate surveying and valuation firms in Abuja, Nigeria. It identified the various knowledge-sharing and collaboration mechanisms used by these firms, analysed their effectiveness, and the impact on the performance outcomes of the firms. To achieve these objectives, eighty-two (82) copies of the questionnaire were distributed to estate surveying and valuation firms in the study area via Google Forms, with a response rate of 85.36%. The data collected were analysed using frequency distribution tables, weighted mean scores, and correlation analysis. Results showed that direct person-to-person knowledge sharing and formal databases were the most common and effective mechanisms for knowledge sharing. IT-based tools, such as document management systems and video conferencing tools, were widely adopted; however, collaborative platforms were underutilised. The study also found that direct person-to-person sharing and formalised knowledge management significantly improve performance outcomes (r =0.284, p = 0.017) and (r =0.500, p < 0.001). Brainstorming, collaborative problem-solving, and digital communication methods also have positive effects, but to a lesser degree. The use of project reviews and Scrum meetings exhibited a complex relationship with performance (r = ?0.987, p = 0.002), being less effective in isolation but beneficial in structured contexts. The study recommends that estate surveying and valuation firms should leverage direct person-to-person knowledge sharing by organising regular face-to-face meetings, mentorship programmes, workshops, and brainstorming sessions to boost their performance.
