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.

Abstract

Researches aim to significantly increase the operational properties of the wood materials without compromising on their environmental significance. The possibility of implementing a fundamentally new approach involving filling the free space in the wood fiber structure with such mineral filler particles as nanosized basalt is shown. The research focuses on solving problems concerned with the optimal quantitative ratio selection for the fine mineral components of wood composite, working out the mineral reinforced material prototypes and testing their hydrophysical and fire-technical properties. The proposed method of highly dispersed wood material reinforcing with basalt nanoparticles allows getting highly water- and heat-resistant as well as eco-friendly raw materials. The composite reinforced with wood fiber is characterized by the decreased level of water absorption values and the significantly reduced smoke emission coefficient.

Abstract

We explore the causal links between service firms’ knowledge investments, their innovation outputs and business growth based on a bespoke survey of around 1100 UK service businesses. We combine the activity based approach of the innovation value chain with firms’ external links at each stage of the innovation process. This introduces the concept of ‘encoding’ relationships through which learning improves the effectiveness of firms’ innovation processes. Our econometric results emphasise the importance of external openness in the initial, exploratory phase of the innovation process and the significance of internal openness (e.g. team working) in later stages of the process. In-house design capacity is strongly linked to a firm's ability to absorb external knowledge for innovation. Links to customers are important in the exploratory stage of the innovation process, but encoding linkages with private and public research organisations are more important in developing innovation outputs. Business growth is related directly to both the extent of firms’ service innovation as well as the diversity of innovation, reflecting marketing, strategic and business process change.
