Delay in the execution of construction projects is a major problem confronting the Nigerian construction industry. If unchecked, it will constitute a setback to the realisation of the infrastructure development component of the sustainable development agenda of the United Nations. This paper compared the causes of delay in public and private building projects in Lagos State, Nigeria with a view to enhancing project time performance. The study was conducted using a random sample of 87 Architectural firms and 88 contracting firms out of a population of 289 and 293, respectively in the study area. These represent 30% of the population of Architectural and contracting firms, in the study area. Data were retrieved from 47 Architectural and 48 contracting firms and analysed using mean score and student t-test. Results from the study indicated that delay in public building projects was mostly due to contractor’s financial difficulties with mean score (MS) of 2.84, rise in materials prices (MS = 2.80) and variations (MS = 2.72). On the other hand, client’s interference (MS = 2.92), rise in materials prices (MS = 2.83) and slow decision by clients (MS = 2.74) were the major causes of delay in private projects. T-test also revealed that the respondents were significantly different in opinion on 12 out of the 30 causes of delay in both project types in the study area.

Procurement System

The traditional contract procurement system is reported to be the most preferred in Nigeria for the execution of construction projects. However, the system has been criticised to be ineffective in terms of both cost and time performances. Owing to scanty empirical evidence to support this claim, this study assessed cost and time overruns in building projects executed in Nigeria using the system. Schedule and cost data of building projects were accessed from randomly selected frontline quantity surveying firms in the study area. These comprised schedule data on 51 public and 41 private building projects as well as cost data on 42 public and 33 private building projects. The data were analysed using frequency, percentage and mean. The findings from the study revealed that both public and private building projects executed in the study area using traditional contract system experienced cost and time overruns to varying degrees. However, the system was more effective in terms of cost performance than time performance.

In China, the frequent safety accidents in building projects seriously affect the sustainable development of construction projects. The paper makes a statistical analysis on the characteristics of ordinary and more serious accidents in building projects from the types of accidents, the trends of development and the characteristics of geographical distribution from 2005 to 2016 in China by using the histogram, trend chart, pie chart and table. It can be concluded that in the recent 12 years, the security situation of construction projects generally fluctuates in a big way and is still not optimistic. Among the five major types of accidents, the electric shock and the lifting accidents have been maintained at a relatively stable and low incidence, and the sloughing accidents have accounted for more than half of the proportion. Accidents concentrated in East China, Central China, North China and Southwest China. The economic development in all provinces and cities in China is positively related to the accident. The greater the total regional economy, the rate of economic growth and the demand for infrastructure construction, the more deaths and accidents in construction projects in the corresponding regions.

Purpose The construction industry plays an important role in the achievement of the 11th and 15th of the Sustainable Development Goals. Efforts have been made by most developing and developed economies toward the achievement of these goals. Despite the efforts being made by the construction industry toward the achievement of these goals, there are still barriers that prevent built environment consultants from advancing environmental sustainability (ES) of construction projects. The purpose of this paper is to identify barriers to ES of construction projects. Design/methodology/approach An extensive literature review on barriers to the adoption of ES was conducted and face-to-face semi-structured interviews of purposively selected built environment consultants in Ghana were carried out. Thematic template analysis of qualitative data was conducted. Findings The key findings from the study include perceived initial costs, lack of knowledge on ES, technological difficulties, external pressures in adopting ES practices and environmental conditions in developing countries. Originality/value The outputs of this study offer strategies which are very significant to the construction industry in embracing ES. Further, the findings contribute to knowledge on achieving the sustainable development agenda.

Private Sector Participation

In developing countries, governments are often unable to implement urban infrastructure construction projects (UICPs) on their own, mainly due to budget and financial resource limitations. The participation of the private sector, through public–private partnerships (PPPs), has been considered as an alternative effective method for increasing the efficiency and productivity of urban infrastructure development. However, in many developing countries such as those situated in the Middle East, attracting private sector investments for UICPs uncovers profound challenges that have not ever been comprehensively accounted for and prioritized. To fill this knowledge gap, this study seeks to determine and prioritize the major barriers and risks faced by governments and urban managers in attracting private sector investments through the PPP schemes launched by developing countries in the Middle East. Based on a Delphi study conducted in Iran as an example, the opinions of 60 UICPs experts in both the public and private sectors were collected and analyzed. Results show that technical and organizational barriers and risks were perceived as the most important to private sector participation, followed by economic and financial barriers and risks, and then political and legal barriers and risks.

The most controversial trouble that happened in the construction projects is Delay. So, the specified research took part to investigate the basic causes in delaying the Kurdistan Region of Iraq. The study gathered information from the insight of contractors, consultants, and owners. A wide literature review has been discussed. The delay causes are recognized built on the identified literature review. These features are characterized into owner-related, consultant-related, contractor-related, material-related, labour and equipment-related, and external-related groups. Twenty- six experienced persons participated in doing the questionnaire surveys to control the relative importance of every cause. The work discovered that the highest five reasons for postponement in building projects are financial difficulties by contractors, variation in prices, postponement in making and appreciative shop diagrams, lack of labour, and mistakes in soil study. Lastly, the probable approaches of dropping plan postponements are suggested. This work helps as a helpful tool for construction experts and academics to prevent reasons for postponement in constructing schemes in Kurdistan.

Wastage Rate

The construction industry is the major solid waste generator in Malaysia. The extensive building and infrastructure development projects have led to an inclination in construction waste generation. The accurate waste composition and quantity are hardly to be measured, as the construction activity is dynamic in nature. Every construction stage produced different types of waste and amount. Therefore, the pattern of waste generated throughout the construction stages need to be identified. This paper critically reviewed construction waste issue in Malaysia in order to identify the gap in research. Based on literature studied, this paper proposes an approach to quantify the wastage rate and develop construction waste standard tolerance for stratified residential building projects. There are six steps in the empirical research approach. First is identification of the stratified residential construction buildings. Second is characteristics of project analyze is similar for uniform investigation. Third is determination of construction stages. Fourth is quantification of the waste generated in the construction projects studied. The fifth step is conduct structure interview with the authorized person. The last step is summation of the recorded quantity and development of construction waste standard tolerance. It is expected that the proposed research approach will be practical for construction waste quantification and for future research undertaken.

Cost overrun in construction projects is a common phenomenon in Iraq. This might occur due to diversity of factors. This study aims to identify the factors influencing construction projects cost that are potentially controllable by main contractors. A field study through a questionnaire survey was directed to a sample of related Iraqi professional engineers from general contracting companies at both public and private sectors. Their opinions on the impact and frequency of each factor were investigated. The questionnaire offered (59) factors classified in (8) categories namely; legislations, financial and economic, design, contractual, site management, material, labor and equipment. The factors were ranked according to the highest Relative Importance Index (RII). The study revealed (10) major factors that are potentially controllable by main contractors namely; labor productivity, sub-contractors and suppliers performance, equipment productivity, site organization and distribution of equipment, experience and training of project managers, scheduling and control techniques, planning for materials supply, planning for equipment supply, materials delivery and planning for skilled labor recruitment. Recommendations to aid contractors and owners in early identification of these factors are also included in this study.
