Drivers of Delays in Infrastructure Procurement

Infrastructure procurement delays are widespread, with nearly 44% of World Bank contracts experiencing significant delays between actual and planned contract sign dates. Delays are primarily caused by:

Key Findings

Procurement Stages:
- The evaluation period (bid or prequalification evaluation) is the most frequent stage experiencing delays across all procurement methods.
- Single-stage, single-envelope tenders saw the longest average contract signature delays among all methods.
Proposed Changes:
- Project Preparation: Investing in site surveys and complete designs reduces the likelihood of delays during later stages.
- Contract Framework: Implementing adaptable contracts with proper procurement methods managed at the outset reduces procurement risks.
- Financing: Prioritizing regular budget approval and cash flow ensures timely project execution.
Capacity and Governance:
- Strengthening institutional procurement capacity and promoting transparent, digital procurement systems can significantly reduce delays.

Summary of Key Points

Over 40% of infrastructure projects face procurement and contract execution delays.
Key drivers include weak institutional capacity, poor project preparation, funding constraints, and environmental factors.
Recommendations focus on capacity building, preventative risk measures, and the adoption of e-government procurement systems.

This report underscores the need for systematic reforms in infrastructure project procurement to mitigate delays and improve outcomes.
