Large Scale Tests

Concerns about the environmental impact of building construction is leading to timber being more commonly used. However, it often faces scepticism regarding its safety in the event of fire. This article provides a point of reference on the fire performance of cross-laminated timber through a review of large-scale tests. Although adequately protecting CLT can make its contribution to fire insignificant, some of the internal surface of an enclosure can be exposed whilst still achieving adequate fire performance. Natural fire tests show that the charring rate and zero-strength layer thickness are higher than commonly used in guidance documents. The type of adhesive used to bond lamellae influences performance where delamination can lead to secondary flashovers, particularly in smaller enclosures. Structural elements can potentially collapse without self-extinction and/or suppression intervention. Tests to date have focussed on a residential context and knowledge gaps remain regarding larger enclosures, such as office-type buildings.

Reliable Methods

<p>Assessing the performance of tunnels in fire is becoming increasingly crucial for the overall usability and durability of the structure. One of the most reliable methods for evaluating the presentation of the concrete during fire in tunnels is by testing. In this work, the fire tests performed on the Victory Boogie Woogietunnel, project Rotterdamsebaan (The Hague, the Netherlands) are discussed. The study aims to assess the fire performance of the cut and cover concrete section when subjected to a tunnel fire curve. A series of 6 fire tests were performed on concrete slabs of the size 5,0 m x 2,4 m x 0,4 m when exposed to Rijkswaterstaat (RWS) fire curve for 120 minutes. Based on the work, one of the main conclusions drawn were that it is necessary to test a large-scale specimen to judge the performance of a protection system accurately. Another important conclusion is that the test specimen should have the concrete mixture which accurately represents the tunnel concrete to avoid uncertainty in the fire induced spalling behaviour of concrete.</p>

Cost Calculations

Advancements of recently developed timber products such as cross laminated timber (CLT) and its increasing application in construction demand economical standardization and unification. Therefore cost calculation of solid wood building systems need to be established. Following the systematic analysis of operation procedures, a research project was carried to gain accurate data on effort and performance values for future cost calculations. The absence of specific literature on cost calculations of timber buildings leads to evaluations based on in-house knowledge without cross company references. So a data acquisition on labor costs and machinery expenses on site is required to obtain primary data and input parameters in the cost calculations. Because of the high grade of prefabrication of timber structures, labor costs are the leading influence parameters. The methodology according to the technique of REFA and the specific circumstances of the timber installation process were implemented into the analysis to generate an appropriate system for the examination of these new building systems. To create a feasible and applicable database of values performance factors and activity values have been examined on site, interpreted and edited for future cost calculation of cross laminated timber assembly works. This survey on site contributes another module in the lack of knowledge to optimize the construction management within the construction process of large scale timber buildings.
