Estimating time and cost is an important mission in the early phase of a construction project, especially in feasibility study. It provides a foundation for making decision whether or not the project is performed on schedule and within budget. Thus, reliability of this estimate plays a key role in measuring the success of a project. This study was carried out to investigate the timecost relationship in building construction projects in Bangladesh. The mathematical equation used in this study is based on Bromilow's equation. The research data were collected from sixty-three completed building projects through questionnaire survey. Type of clients, type of projects, and tender methods are the project characteristics considered in this study. The results of analysis indicated that the Bromilow's time-cost (BTC) models developed for each project characteristic are appropriate due to quite high coefficient of determination and relatively small mean percent errors. Among them, the forecasted model for time and cost according to tender methods is the best fit model. It is concluded that the BTC model could be applied in building construction project to predict its time and cost in Bangladesh. Four different regression models were also developed in this study. The results of BTC model between some selected countries were compared to gain the comprehensive view.

“…According to Babalola and Odediran (2013), construction plays an important role in the economic development of and employment in various nations. Nigeria is not exempt, as Ogunsemi and Jagboro (2006) elucidate that the Nigerian construction industry is important and significant to economic growth and employment generation. Olatunji and Bashorun (2006) noted that the industry has contributed substantially to economic growth (5%-7% improvement in the gross domestic product (GDP) growth, and >42% of the fixed capital growth) over the past 4 decades, while on a global scale, the construction industry accounts for 6% of the GDP (Oluwakiyesi 2011).…”

Abstract:The construction industry did not just evolve on its own. It is a product of the conscious efforts of several individuals called construction workers. In Nigeria, it is a large employer of the population, skilled, unskilled, and professional. However, the Nigerian construction industry, similar to other industries, is currently in a phase of economic reform. This is largely attributed to the present economic situation. The current recession condition of the Nigerian economy has an adverse effect on the income of the citizenry. This implies that other sources of income alongside the basic firsthand means of income generation have to be sourced. This dilemma is more prominent among women. Considering the construction industry, professional female construction workers have been observed to join the league of those involved in ancillary income generation occupations. It is worth noting, however, that there are few professional female construction workers in the first place. This paper addresses whether this drift is a diversification or deviation of Nigerian professional female construction workers to vocational occupations, by a rigorous review of related literature. The result shows that this new trend among professional female construction workers is a welcome one if it is diversification because this will improve the productiveness of the individual involved and, in the long run, better the economy. On the other hand, this work finds that if these vocational occupations make professional female construction workers leave their construction field totally or almost totally, then there is a threat to female population in the construction industry. However, diversification is encouraged.

“…Apart from the fact that they are major contributors to the Gross Domestic Product (GDP) and employment, they constitute the basic infrastructure needed to accommodate the inputs of all other sector of the economy Ogunsemi and Jagboro [4]. Oladapo [5] opines that these are professionals traditionally responsible for production and management of project information and documentation.…”
