The duration of the peer review process at Qubahan Engineering Journal (QENGJ) depends on several factors, including the complexity of the research, reviewer availability, and the number of revision rounds required. The journal aims for an average manuscript turnaround time of 6–12 weeks, although actual processing times may vary.

The standard peer review process includes the following stages:

1. Submission: Authors submit their manuscripts through the journal's online submission system.

2. Initial Assessment: The editorial team evaluates manuscripts for compliance with submission guidelines, journal scope, originality, research ethics, and applicable engineering research standards.

   • Estimated timeframe: 1–2 weeks

3. Reviewer Assignment: At least two independent reviewers are selected based on their engineering or scientific expertise, availability, and absence of conflicts of interest.

   • Estimated timeframe: 1–2 weeks

4. Peer Review: Manuscripts undergo double-anonymous peer review, evaluating scientific quality, originality, methodology, technical accuracy, research significance, and relevance to civil and structural engineering, architecture, computer engineering, construction engineering, sustainable infrastructure, and related disciplines.

   • Estimated timeframe: 1–2 weeks

5. Editorial Decision: The Editor-in-Chief or handling editor evaluates reviewers' recommendations and decides whether to accept, request revisions, or reject the manuscript.

   • Estimated timeframe: 1–2 weeks

6. Revision (if required): Authors revise their manuscripts and respond to reviewers' comments. Additional review rounds may be required.

   • Estimated timeframe: 1–2 weeks

7. Final Decision: The editorial team assesses the revised manuscript, verifies compliance with scientific and ethical requirements, and communicates the final acceptance or rejection decision.

   • Estimated timeframe: 1–2 weeks

8. Publication (if accepted): Accepted manuscripts undergo copyediting, proofreading, formatting, and online publication.

   • Estimated timeframe: 2–3 months (may vary depending on the publication schedule).

Note: These timeframes are indicative rather than guaranteed. Actual processing times may vary depending on manuscript complexity, reviewer responsiveness, revision requirements, and editorial workload. QENGJ is committed to maintaining a rigorous, transparent, independent, ethical, and fair peer review process.
