Abstract
Life-cycle costing is an important part of every construction project, as it makes it possible to take into consideration future costs relating to the operation and demolition phase of a built structure. In this way, investors can optimize the project design to minimize the total project costs. Even though there have already been some attempts to implement BIM software in the Czech Republic, the current state of affairs does not support automated data flow between the bill of costs and applications that support building facility management. The main aim of this study is to critically evaluate the current situation and outline a future framework that should allow for the use of the data contained in the bill of costs to manage building operating costs.
Highlights
Life-cycle costing is an important part of every construction project, as it makes it possible to take into consideration future costs relating to the operation and demolition phase of a built structure
Life-cycle costs (LCC) are among the tools used to assess investment projects that take into account the overall costs during the whole life cycle (WLC) of a project
The pre-investment and investment phases are associated with high initial costs during a relatively short period of time, while the operation phase, which is the longest phase of the life cycle, comes with relatively low annual costs
Summary
Life-cycle costs (LCC) are among the tools used to assess investment projects (including, but not limited to, construction projects) that take into account the overall costs during the whole life cycle (WLC) of a project. 3. Suggested framework of data flow for LCC modelling and management A suitable solution for the Czech construction industry seems to be creating a three-step framework of data flow for LCC modelling and management: 1) aggregating the individual items found in the price database into functional parts of a built structure; 2) obtaining information about the life, frequency of repairs, maintenance, and related costs for the individual structural components; and 3) transferring all the required input data into a model for LCC calculation and evaluation. Frequency of repairs, maintenance, and related costs for the individual structural components Currently, there is a lack of available data about the life, frequency of repairs, maintenance, and related costs, all of which are required for LCC calculation. Where: RMn, Rn, Mn...unit costs of the nth replacement (RM), repair (R), maintenance (M)
