Challenges in takeoffs and cost estimating in the BIM technology, based on the example of a road bridge model

Technical and economic analysis of a construction project carried out using BIM can improve the process of cost-estimating at all stages of design and construction works. More and more designers choose to use BIM within a range of cost estimates; however, in contrast to design software, cost-analysing BIM software is less widespread and used. The following paper presents problems and issues that could be encountered while performing cost estimates and quantity takeoffs applying BIM tools on the example of a model of a road bridge.
