WCTE 2016 - World Conference on Timber Engineering | Year: 2016

Within the WoodWisdom-Net program, a project named "Silent Timber Build" (STB) is now progressing. Impact sound insulation is the dominating task in this project, where development of reliable mathematic models to predict the impact sound pressure level of a floor system is important. But the predictions need to be validated and therefore reliable measurement data is of main interest. This paper presents results from numerous well controlled sound insulation measurements of European wooden joist floor constructions performed in the laboratory. One main difficulty is related to the variation due to different solutions, different materials and components and also, different laboratories. However, the constructions have been "grouped" and it has been presented earlier within the STB project. Results in this paper cover a broad range of joist constructions, but basically intended to fulfil requirements in residential buildings among the involved countries. The paper highlights some specific phenomena, and shows how structural differences related to the grouping of the constructions affecting the impact sound insulation properties.

Modular construction is widely used for residential buildings of four to eight storeys and there is pressure to extend this relatively new form of construction to 12 storeys or more. This paper reviews recent modular technologies, and also presents load tests and the analysis of light steel modular walls In compression. A design method for high-rise modular applications is presented taking account of second-order effects and installation tolerances. For the modular walls tested, it was found that the plasterboard and external sheathing boards effectively prevent minor axis buckling of the C sections, so that failure occurred either by major axis buckling or local crushing of the section. In all cases, the results of the tests on 75 mm and 100 mm deep × I · 6 mm thick C sections exceeded the design resistance to BS 5950-5 by 10 to 40%. However, an eccentricity of 20 mm in load application reduced the failure load by 18 to 36% owing to local crushing of the C section. Tension tests on typical connections between the modules and corridors gave a failure load of 40 kN, which is adequate to transfer wind forces to a braced core and also to provide tying action in the event of loss of support to one corner of a module. Corner posts provide enhanced compression resistance but their buckling resistance is dependent on the sway stiffness of the wall panel. It is also shown that the notional horizontal force approach for steel structures presented in BS 5950-1 should be increased for modular construction.

Environmental Impact Assessment Review | Year: 2012

EIA plays an important role in enhancing the environmental performance of the construction sector. In recent years, the construction sector has been developing green procurement practices. Green procurement is a process that involves the incorporation of environmental requirements during the procurement of services and products. However, discussion on green procurement is rarely seen during the EIA phase. This paper addresses possible opportunities for improving the coordination between EIA and green procurement within the construction sector. The linking of EIA and green procurement has been postulated in the paper as an aid to strengthen the coordination between project planning and implementation. The paper is based on a literature review and is an outcome of an on-going research project concerning EIA and green procurement. This study indicated that it would be appropriate to introduce green procurement during the pre-decision phase of an EIA. In the present study, the opportunities for integrating green procurement at the stage of EIA are associated with the integration of project planning and EIA. Future research should investigate the mechanism through which the link can be established. © 2011 Elsevier Inc.

VANCOUVER, BRITISH COLUMBIA--(Marketwired - Dec. 20, 2016) - PNG Gold Corporation (the "Company") (TSX VENTURE:PGK) provides the following additional information pursuant to its previous press release dated November 10, 2016. Contracts for engineering pre-FEED studies have been entered into with Stantec Engineering ("Stantec") and WSP Canada Inc. ("WSP") to validate the previously modelled second stage design capability of the ReGen™ technology to produce 45% to 53% Group III base oil from used motor oil ("UMO") feedstock in addition to Group II base oil, ultralow sulphur diesel fuel, and asphalt flux from the other two stages in the ReGen™ process. As stated previously, the Company expects these independent studies, being completed by two of Canada's leading engineering firms, will confirm the capability of the revolutionary ReGen™ technology to produce significant volumes of Group III base oil. Upon completion of these two independent studies, which are projected to take 10 weeks to complete, the Company will select one of these firms to move forward with a full FEED study, from which the Company's Board of Directors will have the necessary information to decide if it should proceed with a change of business application to the TSX Venture Exchange ("TSXV") and proceed with constructing the proposed re-refinery. Both Stantec and WSP have been selected for this project following a rigorous process. Upon completion of their respective pre-FEED studies, each firm will submit a detailed proposal and will participate in the competitive bid process for the follow-on engineering work, which will include validation of the Company's current projected $85MM capital cost for a 2,800 barrel per day re-refinery. Santino Pasutto, Oil & Gas manager at Stantec stated, "Stantec welcomes this opportunity to put our specialized knowledge in this field to good work and is privileged to have been engaged in this innovative project. I know that for process engineers this is precisely the kind of project they envision when they decide to pursue this profession. We look forward to building our relationship with PNG, an invaluable industry partner seeking to help grow our economy in new and exciting ways by bringing this cutting-edge facility to Alberta." The Company believes that with current market prices for the commodity products that the re-refinery will produce, the project payback will be completed within the first year of plant operation. Additionally, the Company is in negotiation with UMO collection companies to provide the feedstock quantities necessary to support a 2,800 barrel per day re-refinery, as well as also commencing preliminary negotiations with potential purchasers for all of the off-take products that will be produced by the re-refinery.

Geomorphic modelling is a key method to understand the soft cliff recession process to predict future rates of retreat and responses to climate change. A range of process-based models have been used; however the influence of varied vertical lithology has yet to be quantified. This paper describes modifications to the 2D SCAPE (Soft Cliff and Platform Erosion) model, carried out to explore such interactions between vertical changes in cliff resistive strength and prevailing coastal conditions. As expected, weaker (/more resistant) layers lead to more (/less) rapid retreat. However, this effect is strongly influenced by the position of such layers relative to mean sea level, where the erosive potential is greatest. Moreover, model simulations reveal that layers of variable resistance give an asymmetric response in terms of both rates of retreat and the timeframe for the effect to be realised. For example, a reduction of material strength of 1/5 (in comparison to the remainder of the cliff) about mean sea level results in a rapid 130% increase in the rate of retreat in comparison to the introduction of a five times more resistant layer of the same characteristics. This variation in response can be attributed to the different magnitudes of feedback governing profile reshaping associated with the change in lithology. For example, the introduction of a weaker layer amplifies erosion through its greater erosive potential combined with steepening of the overlying section. The results have important implications for the management of coastal cliffs exhibiting variable stratigraphy, combined with the potential for future interactions with sea-level rise. © 2014 The Authors.

While upgrading Highway 27 in Sweden, a 47,4 m long arch bridge consisting of glulam was built. Due to architectural reasons, the aches were not allowed to be connected to each other above slab level. The moment transmitting joint between the vertical beam hanger and transverse girder results in U-shaped connections between the arches. A 13,9 m spacing of the arches made the design of this structural part challenging. Stability of the arches was especially considered, regarding both in and out of plane buckling due to vertical and horizontal loads. Dynamic factors for the wind load were calculated using a single mode principal. A stress-laminated timber slab made of glulam beams was used as the bridge slab. This glulam - steel hybrid structure consists of approximately 230 000 kg of untreated glulam and approximately 100 000 kg of steel.
