Customer involvement in infrastructure maintenance activities is a complex process due to various decision-making parameters surrounding maintenance. Compared to manufacturing and other disciplines where QFD is widely used, expectations of the infrastructure user as a customer are truly dynamic given the changing economic conditions, technologies, environmental regulations, etc.
The worldwide demand for new concrete buildings is increasing at a rapid pace to keep up with urban development. Despite the need, concrete production and its use have a number of environmental consequences. The production of concrete creates a substantial need for water that directly causes a burden on the already scare natural resource.
Driven by a plethora of external and internal influences, the construction industry has independently embraced lean principles and green initiatives. Prima facie significant synergies have been reported between these two paradigms. It is foreseen that when tapped and adopted in unison, these paradigms may yield additional benefits for the construction projects.
The overarching objective of social housing is to meet housing needs, particularly those of the vulnerable households – low and middle income earners. However, there is evidence to show that social housing is not adequately supported to achieve sustainable goals despite its significance for addressing the housing crisis.
The hedonic pricing model (HPM) technique has been widely adopted for property price appraisal by scholars and professionals in different real estate markets around the world. Despite its popularity in this research domain, the trend of the application of HPM in Nigeria, being the largest economy in Africa, is unknown and has not been documented.
This study discusses the future directions of effective Design for Deconstruction (DfD) using BIM-based approach to design coordination. After a review of extant literatures on existing DfD practices and tools, it became evident that none of the tools is BIM compliant and that BIM implementation has been ignored for end-of-life activities.
Ground granulated blast-furnace slag (designated as GGBS) has been utilized as building material due to the environmental, economic and technical benefits. In this study, the possibility of improving compressive strength of high-volume GGBS (HVS) paste before and after being exposed to elevated temperatures using metakaolin (MK) in micro-size (mMK) has been investigated.
Fez is the most ancient of the imperial cities of Morocco. In Fez the rate of population growth has been spectacular in recent times (484,300 inhabitants in 1982 and 1,129,768 in 2014). The accelerated rate of population growth has generated a large urban sprawl in all its forms and serious environmental problems.
In this paper is presented an approach for landfill leachate treatment using enhanced natural evaporation. Experimental set up considered using a greenhouse pilot prototype placed into the municipal landfill of Puebla city, Me´xico. The greenhouse was built with a basement surface enough to place 9 trays with leachate.
The increase outdoor temperature acts directly on the indoor climate of buildings. In Cameroon, the energy consumption demand in the buildings sector has been rapidly increasing in recent years; so well that energy supply does not always satisfy demand. Thermal insulation technology can be one of the leading methods for reducing energy consumption in these new buildings.
