###### Abstract
An analysis of the implementation factors of ICT and subsequent quantification has not yet been carried out in any research found and included in the review. In particular, in life cycle cost management, it is appropriate to examine and verify the relationship of implementation factors in terms of cost optimization, and whether it is a dimension in the management of construction projects or life cycle cost management of construction projects. The research's basic scientific questions were determined based on theoretical overviews in the given area and a summary of this research. What are the implementation factors of ICT in life cycle cost management? The fundamental research problem is that investment costs are the most critical ICT implementation factor in building life cycle cost management. Based on the literature, interviews with experts (project managers, cost managers, etc. ), and formulation of the research problem, four categories of implementation factors were determined, in which the expected implementation factors were defined to be examined in the survey. These implementation factors were first discussed with selected practitioners. Their comments and expert advice were taken into account for the final formulation of implementation factors. This pre-research ensured a strict selection and formulation of implementation factors. [PERSON]'s alpha was also used to test these questions for the selection of these factors. Implementation factors that were not considered appropriate by the experts were not further investigated. Table 2 shows all research implementation factors. The most important of the these is the first factor (Investment costs of ICTs) from the research hypothesis's point of view. \begin{table}
\begin{tabular}{c c c c} \hline \hline
**Group of IF** & **Implementation Factors (IF)** & & **Description of Factors and Impact on LCC** \\ \hline  & & 1. & Investment costs represent all costs related to the implementation of information and communication technologies, infrastructure modification and all installation costs. Their impact represents an increased cost of acquiring the system in the first year, and ICT should have a lower cost in the later period. \\ Economic factors & 1. & Investment costs for ICTs \\ 2. & System maintenance costs during its lifetime \\ 3. & The need to recruit IT staff to manage ICT \\ \end{tabular} 2. & System maintenance costs during its lifetime service costs. The level of these costs should be lower than the cost savings resulting from ICT implementation in each life phase of a construction project. \\ \hline  & 3. & Wage-related costs for new staff needed to manage ICT. This factor represents the cost burden during the entire construction period or each life cycle stage of the construction project. \\ \hline  & 4. & Compatibility of software solutions \\ 5. & Functional possibilities of the system \\ 6. & Knowledge of the use of ICT in the field \\ 7. & System maintenance and service and the need to upgrade the system (administrative burden, inspections, repairs) & \\ \hline  & 4. & Compatibility of software solutions \\ 5. & Functional possibilities of the system \\ 6. & Knowledge of the use of ICT in the field \\ 7. & System maintenance and service and the need to upgrade the system (administrative burden, inspections, repairs) & \\ \hline  & 8. & User qualification (training and certificates) \\ 9. & User experience (practical experience) \\ Personnel factors & 10. & Readiness and disinterest of users \\ 11. & Ability to embrace innovation and change \\ 12. & Management support \\ \hline \hline \end{tabular}
