On the basis of the facts, it was decided that the standard agreement in the short form had not been included in the contract. The architect had mandated the engineering office on behalf of the client. Although the model was presented to different organizations, even though invoices were issued by the engineering office and paid for by the client, it was found that it was not part of the contract. There is also no sufficient evolution of the treatment, so that the conditions can be considered applicable in the circumstances. While the architect and engineer had collaborated several times, the same arrangement was not attributed to the client. There was also the additional complexity of the architectural office, which was involved over time. While the lessons learned here are not new, they are worth repeating. .
