Methodology of Cost Parameter Estimation for Modern Methods of Construction Based on Wood

Abstract

The modern building systems employ an unceasing development potential of latter building materials and systems. The composition of building structures (walls, roofs, floors, ...) is increasingly difficult due to combinations of various types of materials in order to ensure (create) the structures with the best parameters (thermo-technical, mechanical, user‘s, ....). The production cost, determining the further application of building components on the market, definitely presents one from important parameters. Especially in the area of wooden constructions, there have been increasingly appearing new and new construction-material systems. To explore their structural and material characteristics, the standard analysis, calculations and test procedures are used. However, the determination of their quantities, when estimating the total cost, is problematic. The existing estimating databases providing at least information cost, don’t involve the needed information. Thus, a potential customer is not able to confront the cost of such new construction systems with cost of other systems offered by various suppliers. The paper is focused on construction-technological analysis of the modern construction systems based on wood. Moreover, the proposed methodology of cost parameter estimation is presented. Estimation of Budgetary Index (BI) is based on a case study of a selected construction system based on wood, represented by ten wood houses with different shape and different size.
