In most developing countries the construction costs seem too high to the majority of the population made up of families with very low incomes. One of the means susceptible to contribute to the reduction of costs is its proper mastering. Cost estimation based on matrix approach leads to the description of the principal components of construction cost in a detailed manner. However this model does...

The purpose of this research report is to establish guidelines for identifying highway rehabilitation projects warranting acceleration within Texas. Reduction in the total number of days allocated for project completion is recommended if savings in user costs are greater than the additional costs of accelerating the project. Throughout this report, the short-term impacts to road users and the e...

Submerged arc welding is used widely in oil and gas industry construction for storage tanks, pressure vessels, shipbuilding and etc. One of the processes of submerged arc welding is back gouging operations. This paper presents a way to remove the back gouging operation from the submerged arc welding process. For this purpose, effects of submerged arc welding parameters onA516-70steel sample wer...

one of the most effective tools for decline cost and time, quality improvement and consequently project performance enhancement especially in construction projects, is value engineering. there are linguistic judgments in many cases of value engineering studies in construction projects such as interior design, mechanical installations design, and etc. therefore multiple attribute decision-making...

sustainable forest management in caspian forests of iran requires cost-benefit analysis in order to maintain the quality of timber stands during logging operations. this study was done with the aim of cost and gross revenue computations from current logging (net present value) in three adjacent compartments in district 2 of shafroud watershed. motion and time studies were carried out during fel...

This paper tackles problems encountered in mining of incomplete data for knowledge discovery of construction databases. As historical construction data are expensive to collect, any waste of incomplete data means not only loss of knowledge but also increase of costs for knowledge discovery of construction engineering. Unfortunately, incompleteness is commonplace in the existing construction dat...

Construction projects usually involve high investments. It is, therefore, a risky adventure for companies as actual costs of construction projects nearly always exceed the planed scenario. This is due to the various risks and the large uncertainty existing within this industry. Determination and quantification of risks and their impact on project costs within the construction industry is descri...
