It is recommended that the 2007 version of the paper be retracted. An effort has been made to contact the authors, but unfortunately, my search revealed that the authors have retired and couldn’t have access to the current email addresses of the authors from August 2025 to date.

Retraction notice text (to be published) Retraction Notice Title: Risk Pricing in Construction Tenders - How, Who, What Authors: Marcus Towner and David Baccarini Journal: Construction Economics and Building, Volume 7, Issue 2, 2007, Pages 12-25 DOI: https://doi.org/10.5130/AJCEB.v7i2.2987 Reason for Retraction: This article has been retracted at the request of the Editor- in-Chief and the publisher. Following publication in https://doi.org/10.5130/AJCEB.v7i2.2987 Standardised Retraction Form 2007/2008, concerns were raised recently regarding the duplication of the above paper. There's a major error in the 2007 version of the above- mentioned paper in that it was cut short soon after the 'Risks Considered' subheading of the results section, and the text from an entire article from the previous issue was copied in its place. Even though the correct version was published in Vol. 8 No. 1 (2008), the error wasn’t declared in the 2008 version article or in the editorial, and there's no other indication to a reader that the 2007 version is flawed. An investigation confirmed that portions of the article published in 2008 contained substantial overlap with previously published works by the same authors in 2007 without retracting the first paper published in 2007. Unfortunately, the authors could not be contacted to acknowledged these issues and therefore the Editor-in- chief and the publisher have decided to retract the paper. Statement: This retraction serves to maintain the integrity of the scholarly record of the Construction Economics and Building journal and upholds the highest standards of publication ethics. The online version of this article has been marked as “Retracted.” Date of Retraction: 05/11/2025
