Abstract
The growing pressure to optimise construction
investment costs from the life-cycle perspective inevitably
leads to efforts to seek new solutions that will facilitate
informed decision-making in the early stages of the construction project. Awareness of the importance of considering future operation and demolition costs emphasises
the shortcomings related to the possibility of making
accurate predictions/estimations of such costs, which will
become apparent in the future. To address this research
gap, an innovative approach of life- cycle cost modelling
on the level of individual structures of the building is presented. The model provides users with information on the
costs of available technical solutions resulting from the
requirements of the investor at a specific stage of the construction project. In this way, it helps investors optimise
their building projects and to find the most economical
solutions. Specifically, this model is assembled for the
purpose of selecting a suitable partition wall and, there
fore, it takes into consideration specific characteristics
relating to this particular type of structure. The results
indicate diversity in partition wall structural design variants at the early stage of the project. Since the ability to
influence future costs decreases as the project progresses,
the model allows capturing LCC perspective even if only
a construction study is available without more detailed
technical and economic information. The presented model
aims to contribute to the higher performance of construction projects in the planning phase from the perspective of
LCC and investors’/owners’ point of view.
