In March 2014, the Norwegian newspaper Aftenposten released the first of 45 articles concerning the shadow economy of the Norwegian construction industry. It provided evidence that criminal actors continuously managed to infiltrate the construction supply chain. Therefore, this paper investigates the following research questions:1) What are the main challenges regarding work-related crime? 2) How do contractors manage their reputation in the aftermath of work-related crime executed by subcontractors? This exploratory study started with a literature review. It was followed by a case study based on a document study and 12 semistructured in-depth interviews with representatives on strategic level. Some particularities of the AEC-industry makes it vulnerable to work-related crime. Complex supply chains, autonomous project managers measured on net profit, high weight on price etc. are examples of characteristics. The literature review reveals a knowledge gap regarding the current state when it comes to crime and crime-prevention within the industry. The findings indicate that the contractors managed the reputational challenges that emerged in the aftermath well on a strategical level. This was accomplished by clearly distancing themselves from the criminal actors within their projects, while still taking responsibility for correcting the situation. In this case study, the client even expressed increased trust in the major contractor after experiencing how the major contractor handled the situation. However such an approach might work the first or second time, but such an approach might work a couple of times, but with repeated infiltration of criminal actors the contractors have to do more than distancing themselves. Future research should focus on how contractors work to prevent workrelated crime on the operational level.

Construction companies can be difficult to manage because of complex supply chains, autonomous project managers aiming to maximize net profit, heavy emphasis on price, etc. Another particularity, namely the construction companies' vulnerability for work-related crime, does not receive sufficient attention in the project management literature. In order to study how two major Norwegian contractors managed to safeguard their reputation in the aftermath of the discovery of tax crime and money laundering within their projects, this paper investigates the following research questions: 1) What are the main challenges regarding work-related crime? and 2) How do contractors manage their professional reputation and public image in the aftermath of exposed work-related crime?This is an exploratory study starting with a literature review, followed by a case study consisting of a document study and 12 semi-structured in-depth interviews with representatives on the strategic level. Work-related crime could have a devastating effect on a contractor's reputation. Reputation is perceived to be a vital catalyst for contractors that want to continue in business and conduct projects for reputable clients. Therefore, the most important measure will be to deliver projects according to the agreed price and quality, within the scheduled time, while not compromising either the contract, all the legal jurisdictions aspects or ethical standards. In these particular cases, the contractors perceived their reputation as remaining untarnished due to their successful ad-hoc reputation management. However, the contractors have to do more than just distancing themselves. They must actively prevent criminal actors from entering their projects. This paper is a revised version of the paper (study) published earlier in the proceedings of the Creative Construction Conference 2018 (Engebø et al., 2018).
