“…Cost of a project is one of the most important key elements for time performance in Australia [3,6,7,28,31]. Furthermore, a similar research performed by Ireland [17] showed that the average construction time can be well predicted by cost based on an analysis of 25 high-rise commercial buildings projects in Australia.…”

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.

“…Attempts to predict construction durations represent a problem of continual concern and interest to both researchers and project managers (Bromilow and Henderson, 1976;Bromilow et al, 1980;Ireland, 1983Ireland, , 1985Ireland, , 1986Sidwell, 1984;Walker, 1990;1994a,b,c,d, 1995Nkado, 1992Nkado, , 1995Chan and Kumaraswamy, 1995;Kumaraswamy and Chan, 1995). Given the signi® cant impact of the property and construction sector on the Hong Kong economy, this paper attempts to establish a time± cost relationship based on 110 building projects in Hong Kong.…”

The duration of Australian construction has been modelled by a time-cost formula expressed in the form of T=KCB, where T is the actual construction time in working days, C is the final cost of contract in millions, K is a constant characteristic of building time performance, and B is a constant indicative of the sensitivity of time performance to cost level. This paper applies the relationship to building projects in Hong Kong using time and cost data from 110 projects. Regression analysis was used to compute the values of K and B and check how well the model actually fits, and the best predictor of average construction time of building projects in Hong Kong is found to be T=152C0.29. It is also found that the Hong Kong private sector takes a shorter time (120 days) to complete a hypothesized project with a contract sum of HK$1 million (at December 1994 price) than its government counterpart (166 days). The time-cost relationship serves as a convenient tool for both project managers and clients for predicting the actual optimum time required for delivery of a building project.Time Cost Relationship, Regression Model, Building Projects, Hong Kong,
