In order to assure an objective assessment of BIM managers' performance, standards to assess the skills and
competence of construction professionals in using Building Information Modeling (BIM) got to be set. This paper aims at
creating some rating criteria to assess the performance of BIM managers in Iraq through a pilot study. A new technique of
performance assessment known as Multi-Source or 360° feedback method was employed for this purpose aided by a
questionnaire form specially designed to match the technique and the purpose. The Center of Engineering Consultancy at
the Ministry of Industry and Minerals was chosen to implement the pilot study for it is the first firm that initiates the
application of BIM in Iraq. It was found that performance assessment of the BIM managers is quite different among
constituents (bosses, peers, staff, contractors and clients) especially when compared to the BIM managers' self-assessment
which was always over-estimated. The highest degree of assessment was found to be (3.975) out of (5) degrees for the best
BIM manager. This indicates the necessity of adopting such objective approach in the organization culture instead of
personal judgment of bosses. As a result, the use of Multi-Source feedback method in assessing the performance of BIM
managers proved to be successful and can be used in other firms in the Iraqi construction sector.
