AN ANALYTICAL APPROACH TO OPTIMIZATION OF THE COSTS FOR CONSTRUCTION FORMWORK

The costs for construction formwork create a significant item in the construction budget. Several studies suggest that the costs for construction formwork are in Slovakia, on average about 25% from the total costs of the concrete structure, abroad it is around 30%, depending on the territorial differences in the price of labor and materials. Therefore, optimizing the costs for construction formwork is a current topic. Planning of the deployment of construction formwork elements to the construction schedule creates a dynamic role, because the time factor greatly affects the costs for formwork. The paper deals with a specific task: optimizing the costs for formwork elements for a given number of workspace zones with a gradual deployment of construction formwork. Task, focuses on leveling the number of elements/sets of formwork particular type in subsequent workspace zone, is extended to assess the extent to which is the proposed solution optimal.
