The productivity of the construction industry worldwide has been declining over the past 4. One approach for improving the situation is using lean construction. Lean construction results from the application of a new form of production management to construction.

An increasing number of construction academics and professionals have been storming the ramparts of conventional construction management in an effort to deliver better value to owners while making real profits. As a result, lean based tools have emerged and have been successfully applied to simple and complex construction projects. In general, lean construction projects are easier to manage, safer, completed sooner, and cost less and are of better quality. Significant research remains to complete the translation to construction of lean thinking in Egypt. This research will discuss principles, methods, and implementation phases of lean construction showing the waste in construction and how it could be minimized. The Last Planner System technique, which is an important application of the lean construction concepts and methodologies and is more prevalent, proved that it could enhance the construction management practices in various aspects. Also, it is intended to develop methodology for process evaluation and define areas for improvement based on lean approach principles. ASTM develops technical standards for industry worldwide. Materials Your. Home. Every building material comes with an environmental cost of some sort. However, some principles can help guide your choice of sustainable materials and construction systems. Careful analysis and selection of materials and the way they are combined can yield significant improvements in the comfort and cost effectiveness of your home, and greatly reduce its life cycle environmental impact. The first step in any strategy to use sustainable materials is to reduce the demand for new materials.

ELECTRICIAN CONSTRUCTION AND MAINTENANCEAPPRENTICESHIP Program Code 0506X01FWO. Registration for Apprenticeship programs takes place. Rather than knocking down and rebuilding a home, its worth trying where possible to renovate or at least reuse materials from the existing home. Consider building smaller, well designed houses and minimising wastage by using prefabricated or modular elements, for example, and by avoiding unnecessary linings and finishes. During design and construction, incorporate approaches that will make it easier to adapt, reuse and eventually dismantle the building. By choosing durable, low maintenance materials, you can minimise the need for new materials and finishes over the buildings lifetime. Photo Paul Downton. The next step is to select materials with low environmental impact. Put simply, a sustainable material is one that does not impact negatively on non renewable resources, the natural environment or human health. Most products have a net negative impact on the environment however, its important to minimise the negative impacts of any materials you choose. When looking at the environmental impact of a material or product, consider all stages of the life cycle the upstream stage materials extraction and manufacture, the in use or operational stage, and the downstream stage disposal or reuse. Life cycle assessment LCA is a highly detailed scientific analysis that examines all the life cycle impacts of a product in great detail. Keygen Php Maker 10. An LCA quantifies the majority of known chemical, physical, resource based and energy impacts of a material or product. It provides us with increasingly more comprehensive and useful assessments of the sustainability credentials of products and materials, allowing better and easier comparisons between products. Although some progressive housing companies and developers are starting to embrace LCA, a customised LCA may be beyond the scope of many home building or renovation projects. Selecting products with low life cycle impact can be complex as there are many issues to take into account. However, there is decision making support available. Eco product selection databases such as Ecospecifier enable you to access information on the sustainability credentials of a broad range of materials and products. Product assessment schemes, many of them based on LCA, allow you to make even more informed comparisons. These include Ecospecifier Verified, BREEAMs Green Guide and Global Green. Tag. Linked to such assessment schemes is a range of ecolabels including Good Environmental Choice Australia GECA, Global Green. Tag. Cert. TM and the FSC Forest Stewardship Council. The articles in this section cover different types of construction systems and materials. Each reviews the benefits of the particular system or material but also lists things to watch out for, such as construction issues. Informed decisions about materials and construction systems can significantly reduce the environmental impact of a home without adding to the cost. Embodied energy. Embodied energy is the energy consumed by all of the processes associated with the production of a building, from the mining and processing of natural resources to manufacturing, transport and product delivery. Embodied energy does not include the operation and disposal of the building material. This would be considered in a life cycle approach. Embodied energy is the upstream or front end component of the life cycle impact of a home. Choices of materials and construction methods can significantly change the amount of energy embodied in the structure of a building, as embodied energy content varies enormously between different materials. However, assessing the embodied energy of a material, component or whole building is often a complex task. Another significant factor in reducing the impact of embodied energy is to design long life, durable and adaptable buildings. Waste minimisation. Around 1. 8. 2 million tonnes 4. Australia is building waste. A lot of energy and resources go into the manufacture and transport of materials used to construct a home, yet eventually 6. Blue Environment and Randell Environmental Consulting 2. Minimising and recycling waste can have significant social, economic and environmental benefits. The three Rs of waste minimisation reduce, reuse, recycle should be applied throughout the design and construction process reduce or avoid demand for materials by renovating rather than demolishing and rebuilding, and building smaller homes that are better designed for your needs reuse existing materials or building components and recycle materials rather than sending them to landfill. Construction systems. The combinations of materials used to build the main elements of our homes roof, walls and floor are referred to as construction systems. Pf Withdrawal Forms 19 And 10C. They are many and varied, and each has advantages and disadvantages depending on climate, distance from source of supply, budget, maintenance requirements and desired style or appearance. Important factors that may influence your choice of construction system include its durability, life cycle environmental impact, life cycle cost effectiveness, role in improving thermal performance, and reuse or recycling potential, as well as local availability of materials and skills needed to construct the system. Lightweight framing. Lightweight framed construction is the most popular construction system in Australia. Steel and timber, the two most commonly used framing materials, can contribute to the comfort, appeal and environmental performance of a home. By assessing environmental impact, structural capability, thermal performance, sound insulation, fire resistance, vermin resistance, durability and moisture resistance, owner builders can come to a decision on what is the best option for their situation. Brickwork and blockwork. Bricks and blocks are components of durable masonry construction. They consist of high mass materials with good compressive strength formed into units that can be lifted and handled by a single worker. Materials used can include brick, stone e. They vary in environmental impact, structural capability, thermal performance, sound insulation, fire resistance, vermin resistance, durability and moisture resistance. Of the many kinds of bricks and blocks used in modern Australian house construction the most common are made from concrete or clay. Cladding. Cladding is a non loadbearing skin or layer attached to the outside of a home to shed water and protect the building from the effects of weather. Your choice of cladding has significant implications for the environmental performance of your home. Initial environmental impacts such as embodied energy, resource depletion and recyclability must be balanced against maintenance and durability appropriate to life span. Many different cladding options are available, some best suited to specific applications. Concrete slab floors. Concrete slab floors come in many forms and can play a significant role in thermal comfort due to their high thermal mass.
