With annual average rainfalls of 59 mm and 1180 mm respectively, the difference in renewable water availability between Saudi Arabia and Ireland is stark. For both countries, until recently, the price of water for domestic consumers has been zero or almost zero. Per capita water usage was high, and the cost of providing the supply was heavily subsi...

Alternative project delivery approaches have been proposed to overcome the inefficiencies of conventional delivery methods such as design-bid-build. Integrated Project Delivery (IPD) has recently emerged as a feasible substitute to traditional project delivery approaches. Despite widespread awareness of the benefits of IPD in integration with infor...

The aim of this study is to identify the advantages and limitations in the implementation of the Building Information Modelling (BIM) and Integrated Project Delivery (IPD) in the UK consulting sector. A literature review critically analyses the existing literature, (including online articles and publications owing to the current and fast-moving nat...

Forecasting the cash flow for infrastructure projects has not received much attention in the existing models. Moreover, disregarding the cost flow behaviour and proposing models that entail a relatively high dimensionality of inputs have been the main drawbacks of the existing models. This study proposes a heuristic cash flow forecasting (CFF) mode...

Purpose - High-level labor waste is a major challenge in construction projects. This paper aims to identify, quantify and categorize labor waste in the context of Iranian housing construction projects. Design/methodology/approach – This research uses a case study approach, with empirical data collected through direct observations and semi-structure...

In 2015, increases in the domestic water tariff in Saudi Arabia were met with significant opposition. Although the increases were needed to address the technical and financial sustainability of the service in the context of extreme scarcity and high costs, insufficient effort was made to explain the changes and prepare the public. This paper examin...

The use of untreated household greywater for home garden irrigation is an increasingly common phenomenon in the water-stressed Middle East and North Africa (MENA) region, particularly among the poor. Most decentralized systems to date have proven to be relatively costly with doubts over their long-term financial viability. This paper describes some...

Jordan faces continuing growth in water demand, far outstripping its limited renewable resources. Significant efforts have been deployed by the government to maximize the capture of surface water and groundwater, and to develop non-conventional sources such as brackish groundwater, fossil ground-water and treated wastewater. However, with agricultu...
