*3.2. Reliability and Sufficiency of the Data*

In view of the compiled documentation of the tenders, reliable and objective outputs from their analysis can be drawn. This is related to two reasons. First, since the documents of the assembled tenders reflect real-life cases from the construction community and they will be subjected to the CAA, they are precious for presenting reliable findings to the construction management literature. This has been assured by Li et al. [28] that analyzing real documented construction data using the CAA affords more trustworthy results than those relevant to the questionnaire survey and interview. Second, several studies—in which the data sources are real construction contracts, documents, and reports as well as the CAA are their major analytical tool—have been conducted based on a smaller sample of the construction documentation than that collected in the current research. For instance, the common causes of claims in Canada have been defined relying upon the data of 24 construction claim reports [29]. In addition, in the United States, Nguyen et al. [27] investigated the allocation of the risks in the public–private partnership (PPP) scheme on the basis of the content analysis of 21 contracts pertinent to the PPP projects. Undoubtedly, this empirical examination of the prior works indicates that the obtained data (i.e., 34 tenders) represents an acceptable sample for performing the CAA, and thus, it can be deemed as a firm foundation to afford objective results.
