Engineered Wood

This paper presents the development of a visual inspection methodology for engineered wood products that are commonly used in residential construction in the USA. Engineered wood products include wood composite structural elements such as I-joists, oriented strand board, and structural composite lumber products, and metal plate connected wood trusses. Due to the proprietary nature of wood composite engineered products, there are no uniform standards between different manufacturers for installation and use. If improper installation methods are used, engineered wood products may not be able to safely carry design loads. Improper use or modifications constitute prescriptive code violations. Construction errors that result from the unique installation requirements demonstrate the need for specific inspection methods to detect installation errors early in the construction process. The goal of this research is to develop an expert-validated visual inspection methodology, associated knowledge base, and software application for selected engineered wood products and hanger hardware for non-compliance at the pre-drywall stage of new residential construction. A modified Delphi method was used to solicit and refine inspection methods from subject matter experts. Based on these results, an inspection method and computer software application were developed. The method establishes a systematic expert-validated inspection procedure that identifies known high-risk areas for installation problems for engineered wood products. The software contains the instructions for implementing the inspection method, a reference library of authoritative installation guidelines and illustrations, the ability to document observed defects, and a vehicle to create a report. The experts validated the method and software application, and confirmed the usefulness for detecting construction errors.

Current Water

Australia is a relatively dry continent with an average runoff of 50 mm per year. The use of water resources in some river basins is approaching the limits of sustainability. Some adverse environmental impacts have been observed resulting from water diversions and from both reclaimed water and stormwater discharges. The paper describes current water recycling initiatives in Australia. These include: beneficial reuse of reclaimed water for urban, residential, industrial and agricultural purposes; recycling of greywater and stormwater; advanced treatment using membrane technology; and water efficient urban design. Some possible water recycling scenarios for Australia in the 21st century are examined. The implications of these scenarios are discussed.

AbstractIn Humboldt Bay, tectonic subsidence exacerbates sea-level rise (SLR). To build surface elevations and to keep pace with SLR, the sediment demand created by subsidence and SLR must be balanced by an adequate sediment supply. This study used an ensemble of plausible future scenarios to predict potential climate change impacts on suspended-sediment discharge (Qss) from fluvial sources. Streamflow was simulated using a deterministic water-balance model, and Qss was computed using statistical sediment-transport models. Changes relative to a baseline period (1981–2010) were used to assess climate impacts. For local basins that discharge directly to the bay, the ensemble means projected increases in Qss of 27% for the mid-century (2040–2069) and 58% for the end-of-century (2070–2099). For the Eel River, a regional sediment source that discharges sediment-laden plumes to the coastal margin, the ensemble means projected increases in Qss of 53% for the mid-century and 99% for the end-of-century. Climate projections of increased precipitation and streamflow produced amplified increases in the regional sediment supply that may partially or wholly mitigate sediment demand caused by the combined effects of subsidence and SLR. This finding has important implications for coastal resiliency. Coastal regions with an increasing sediment supply may be more resilient to SLR. In a broader context, an increasing sediment supply from fluvial sources has global relevance for communities threatened by SLR that are increasingly building resiliency to SLR using sediment-based solutions that include regional sediment management, beneficial reuse strategies, and marsh restoration.
