Digital Bidding: A Systematic Evaluation of Electronic Reverse Auction Adoption in Philippine Construction Procurement Management

Electronic Reverse Auctions (eRAs) are emerging as a modern procurement method in the Philippine construction industry, supported by providers with experience across major construction firms, universities, real estate developers, and project management organizations. Research shows that eRAs deliver greater cost efficiency and transparency than traditional sealed bidding, while reducing opportunities for corruption through third‑party facilitation. Despite these advantages, the sector continues to rely on manual, paper-based processes that lack real-time price competition, consistent auditability, and standardized digital procurement guidelines. This study examines the application of eRAs in construction management and develops guidelines to help industry stakeholders better understand and adopt this method Through interviews and surveys; key themes and implementation factors will be identified and organized into a structured framework. The findings aim to fill existing gaps in procurement practice and promote wider use of eRAs to enhance efficiency, transparency, and fairness in the Philippine construction sector.
