Public Procurement Practices and Architectural Design Outcomes in Public Buildings: Evidence from Auchi Polytechnic, Auchi, Edo State, Nigeria

Public procurement systems constitute a critical institutional mechanism through which governments translate development priorities into physical infrastructure. In Nigeria, the enactment of the Public Procurement Act (PPA) 2007 introduced regulatory reforms intended to strengthen transparency, competition, and value-for-money in public contracting. While these reforms have improved accountability in government expenditure, persistent concerns remain regarding the functional performance and architectural quality of many publicly funded buildings, particularly within tertiary educational institutions. This study examines how procurement practices shape architectural design outcomes in public buildings within the Nigerian institutional context. Drawing conceptual insights from infrastructure development in Auchi Polytechnic, Edo State, the study adopts a theoretical and literature review methodology to synthesise recent scholarship on procurement governance, construction management, and architectural performance. The analysis reveals that procurement structures particularly cost-dominated tender evaluation systems, fragmented decision-making processes, and limited professional integration during procurement planning significantly influence how architectural designs are translated into built outcomes. Evidence from Nigerian institutional projects indicates that procurement systems focused predominantly on financial compliance frequently produce buildings that satisfy contractual specifications but fall short in terms of spatial functionality, durability, and architectural coherence. The paper argues that improving public infrastructure outcomes requires procurement governance frameworks that recognise architectural design quality as a strategic dimension of public investment. The study concludes by recommending institutional reforms that strengthen professional participation in procurement processes and integrate architectural performance indicators into procurement evaluation frameworks.
