### Criteria for the Selection of Respondents  
Initially, the criteria (Table 1) were set, which should be met by the respondent for inclusion in the examined sample. The first condition was that the respondent had to work for a general contractor, because in Slovakia the general contractor is responsible for on-site HS both during preparation and construction. For several reasons, designers do not use the PtD approach, in contrast to other countries such as Great Britain, Singapore, Australia, the USA and China [15]. Firms specializing in HS inspection during construction were excluded since their participation is minimal. These companies rarely use BIM, and inspectors are forced to fill in e-forms and assign HS tasks to other responsible persons on-site mostly when the general contractor uses a CDE system. Larger general contractors have HS coordinators as members of the team that prepares the construction schedule, quantity take off and cost estimation, so they use BIM more regularly.  
To be included in the survey (Table 1), the chosen professional must work in one of the following positions:  
* BIM coordinator/manager: implement BIM in the company and on the construction site, create exchange information requirements (EIRs), BIM execution plans (BEPs) and BIM manuals, manage, check and create building information models and perform other activities related to BIM.
* Project manager/construction manager: responsible for organizing the construction processes, HS, construction costs and implementing on-site digitization.
* Health and safety coordinator: responsible for preparing the HS plan and ensuring compliance with HS on the construction site, which includes mentoring and administrative responsibilities.  
The last criterion is that the company where the respondent works must use BIM on its projects or undertake to implement one within one year, in which case it should already have created specialized BIM positions or have dedicated employees with the necessary BIM expertise.  
Recommendations and contacts for companies meeting the criteria (Table 1) were obtained from the BIM Association Slovakia [68], which is a member of the Construction Classification International Collaboration (CCIC) [69]. The association brings together

companies to support the implementation of BIM, organizes BIM events for students and professionals, develops recommended national standards in specialized working groups and has members in CEN/TC 442 working groups [70].  
A total of 18 people meeting the criteria were contacted for the survey (Table 1). A more detailed specification of the respondents can be found in Table 2.
