Further steps in application of BIM for budgets of transportation constructions

Popis výsledku v původním jazyce

The article focuses on new attitudes which may create a shift in calculating budgets for transportation constructions. New attitudes rely on the use of Building Information Modeling (BIM). Current schemes of work have reached its limits and nowadays, it is necessary to define further steps leading towards a full match of BIM data to budget items. The author sees opportunities in defining graphic standards to be linked to construction shapes (realistic images of constructions as elements in BIM lead to generating accurate quantities for takeoff), as well as individual construction elements (an element in BIM relates 1:1 to a budget item). In the foreseeable future, it is possible to add classification codes of elements so that element parameters make it possible to match every single element to a budget item. This would link BIM model data directly to the budget of construction project. The last of author’s suggestions is to implement itemization of elements and include a larger scope of aggregation in the project’s budget. Itemized elements serve to match so-called carry items (such elements that may be linked to BIM model with ratio 1:1) to additional tie-in items which are not commonly included in BIM models (e.g. formwork, reinforcement, etc.). This should simplify the import of data to software which calculates the budget of project. The process focuses on aggregation of items to fit local price systems and budget calculation practices. Larger scope of aggregation enables us to reach 1:1 ratio of model and its budget to a greater extent. The suggested shift in attitude has been tested on two transportation construction projects – namely finishing of D1, the key motorway of the Czech Republic, and D4 motorway (also in the Czech Republic).
