Ghanaian construction projects encounter a number of challenges, including low health, safety, and environmental requirements, poor performance, and time and cost overruns. 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.
