Abstract
Abstract he construction industry is one of the industrial sectors with the lowest rates of fulfilment of contract deadlines, especially in developing countries. This fact has been the focus of considerable discussions seeking to identify the causes of the delays. The main purpose of this paper is to use factor analysis to identify the factors that are correlated with delay, contemplating exclusively residential real estate projects and using a city in the Brazilian Amazon as a case study. Based on the database from the government agency that authorises constructions in the city of Belém (City Planning Department - Secretaria Municipal de Urbanismo, SEURB) and data from construction companies, the study investigated 274 construction projects from the past 11 years. Factor analysis and work with the variables that can be identified and measured in the initial phase of the project, i.e., during the feasibility study, demonstrate that the physical characteristics of the apartments and the construction project are the primary causes for variations in construction delays; these causes have not yet been reported in the literature. We hope that the results of this study will contribute to more consistent forecasting of construction time, minimising the risk of delays.
Highlights
In 2012, the construction industry in Brazil contributed with 5.6% of the country’s total gross domestic product (GDP) and 21.4% of the national industrial sector’s revenue (INSTITUTO..., 2015)
The goal of this research study was to use factor analysis to identify aspects of construction delays that have been less explored in the literature and to correlate some factors that may impact construction delays
This study used 18 variables, which are identified in Table 4; other factors are likely to contribute to delays in construction projects
Summary
In 2012, the construction industry in Brazil contributed with 5.6% of the country’s total gross domestic product (GDP) and 21.4% of the national industrial sector’s revenue (INSTITUTO..., 2015). The construction industry has not been able to fulfil all its potential for growth in Brazil. The country still has a significant housing shortage: 5,792,508 units in 2012, with 9.1% of the population not having adequate housing (FUNDAÇÃO..., 2014). This gap demonstrates the importance of developing consistent housing policies that can meet the demand without failing to meet customers’ cost, time and quality requirements. Due to the evident need for housing in Brazil, construction time is a crucial factor. Companies should be able to identify the factors that can affect their ability to meet the project’s objectives before construction begins (GÜNDÜZ; NIELSEN; ÖZDEMIR, 2013)
