To provide value for money (VFM) on government infrastructure projects in Ghana, this research assesses the roles of project consultants, specifically architects and quantity surveyors, and highlights important obstacles. A cross-sectional survey design involving architects and quantity surveyors yielded a 96% response rate after 100 questionnaires were distributed. Consultants’ responsibilities also include monitoring standards compliance, providing advice on delays, controlling budgets, and advising on project completion dates. Difficulties encompass a lack of promptness in decision-making, unethical conduct, political pressure, and inadequate focus on contract administration and construction audits. Project urgency, longevity, political clout, timely decision-making, and team experience are important variables that impact VFM. Policy makers and construction management practitioners should take note of the implications for Ghana’s public infrastructure projects.展开更多
