- Description: Abstract: For many years, the construction industry (CI) has been considered as one of the most dangerous industry due its H&S statistics expressed in terms of accidents and injuries which remain high. Notwithstanding the fact that many research studies have been conducted at both academic and industry level to find solutions, it can be rightly argued that the H&S performance in the CI is still questionable. One of the factors that have impacted negatively on the H&S performance in the CI is the competitive nature of the CI where most clients award their contracts based on price. Consequently, this practice has compelled contractors to lower their bid amounts leading to H&S being marginalised...

- Description: Abstract: The construction industry is increasing in size, technology complexity, interdependencies, and variations in demands from clients. It is of huge significance for an organisation to analyse and identify how well it is performing, and to know the appropriate catalyst that stands to be utilised, to ensure ultimate performance. However, the purpose of this paper is to determine whether there is a difference in the perception of consultants and contractors on the factors affecting the performance of construction projects. The methodology adopted in this research was a quantitative research approach. Data was collected using a questionnaire. The questionnaire aimed at 60 respondents which were civil engineers, quantity surveyors, construction managers, architects, project managers and contractors. Result from the findings revealed that consultants see conformance to specification being more important whereas contractors see, late payment from owner to contractor being more vital.

- Description: Abstract: Poor construction waste management is one of the major causes of project failure in the construction industry and one of the ways of mitigating the challenge is through the use of lean management (LM). This study examines the use of LM to enhance effective productivity in the South African construction industry. 60 well-structured questionnaires were administered on construction professionals such as architects, quantity surveyors, civil engineers, project manager and construction manager out of which 42 were retrieved. Lean management mostly focused on adding value to the product as well as reducing waste in time of things in cycle, it also reduce waste of time through effective time management as well as reduce waste of materials and energy. This indicated that with lean management, everyone becomes a thinker and a creator of something. These requirements are known as willingness to change and the potential self-disapproval. If fully implemented, LM will enhance better construction productivity through reduced inventory, less process waste, just in time delivery, minimize inventory, the use of adequate equipment, encourage collaboration, improve teamwork, improve construction productivity, improve leadership skills and improve labour flow reliability. It was further revealed that the main significant aspect that lean management evolve around is culture, because the culture of lean is subjected on workers being entirely involved and accepted to practice the lean application in common trainings as well as their tasks. It is therefore necessary for construction organizations and concerned parties to improve level of awareness of construction stakeholders especially construction workers on lean management system through workshops, advertisement, training, etc. This will not only aid better productivity in the industry but will also ensure that clients are provided value for their money.

- Description: Abstract: The South African construction industry, like most construction industries worldwide, is facing several problems and challenges that directly affect the performance of construction projects undertaken in the country. Project performance can be measured and evaluated using a large number of performance indicators that could be related to various dimensions (groups) such as time cost, quality, client satisfaction, client changes, business performance, health and safety. However the abovementioned factors are not the only factors that affect the performance of construction projects; therefore this paper aims to establish the most critical factors affecting the performance of construction projects in South Africa, a case study of the Gauteng Province. The data for this paper was collected from both primary and secondary sources. The primary data was acquired through the administration of structured questionnaires. The questionnaire was distributed to construction professionals. The questionnaire was designed based on information emanating from an extant review of literature. Out of the 160 distributed questionnaires, 131 were received back which represented 82% response rate. Findings from the questionnaire analysis revealed that the key factors affecting the performance of construction projects in Gauteng are: cash flow, dispute management (Client and professionals), leadership skills of project manager, speedy and reliability of service to client, dispute management (labour and supervisor), learning from best practice and experience of others, review of failures and solving them and Availability of personnel with high experience and qualification. The study contributes to the body of knowledge on the subject of factors affecting the performance of construction projects in Gauteng, South Africa.

- Description: Abstract: Construction Projects are often delivered under a complex and uncertain environment, with claims and conflict being an inevitable part. It is vital to manage claims and conflict as soon as possible, in order not to turn into disputes. The intent of this paper is to investigate dispute causation in construction projects in Swaziland, and to examine the methods to minimize construction disputes in construction projects in Swaziland. The data used in this study were derived from both primary and secondary sources. The secondary data for the study was derived from the review of literature. The primary data was obtained through the use of a questionnaire which was distributed to client (government), contractor and consultant representatives (quantity surveyor, civil engineer, architects, project managers and mechanical and electrical engineers). Only organizations registered with the ministry of public work and transport in Swaziland and other professional bodies were surveyed. Findings from the survey revealed that the major factors contributing to the causes of construction dispute in construction projects of Swaziland can be classified into: client related factors, contractor related factors, design related factors, contract related causes, project related factors and external related factors. Finding on ways to minimize dispute in the Swaziland construction projects, it was found that supply chain management, partnering, and alliancing are the effective way to minimize dispute in the construction industry.

- Description: Abstract: The competitive nature of the construction industry (CI) has marginalised health and safety (H&S) on construction projects. Most clients in the CI, if not all, award projects based on price and in most cases to the “cheapest bidder” and not the “safer bidder”. Consequently, such practices have compelled contractors to lower their bid price to increase their chances of being awarded projects, whereas in contrast, H&S is marginalised. The study, which was a case study of nine projects of which six were civil engineering projects and three building construction projects, was purposed to conceptualise a model for pricing H&S on construction projects. The findings showed that contractors do price for H&S using an itemised breakdown even though such items are not included as a trade in the Bill of Quantities (BOQs). With regards to expenditure, the actual costs of H&S ranged between 2.9% and 3.98% for projects with a value below R500 million and between 4.08% and 4.90% for projects with a value above R500 million. Health and safety costs were found to be directly proportional to the projects value and indirectly influenced by the client. Previous studies recommended that H&S should be priced as an itemised trade in the BOQs, but such recommendations are yet to be implemented. The lack of a conceptual model for pricing H&S on construction makes accurate and adequate monitoring of H&S costs unlikely. Thus, a standardised pricing model will assist contractors to price adequately for H&S, and clients, to ensure that provision for H&S measures on construction projects is adequate as required by the Construction Regulations (CR) 2014.

- Description: Abstract: Construction projects are complex, risky and time-consuming undertakings that are usually commissioned by governments and delivered by national and international participants with a variety of cultural differences, backgrounds, political systems, and languages. The South African construction industry operates in a uniquely projectspecific and complex environment, combining different investors, clients, contractual arrangements and consulting professions. It impacts directly on communities and the South African public at large, and its improved efficiency and effectiveness will enhance quality, productivity, health, safety, environmental outcomes and value for money. Therefore, this paper will investigate measure that can be used to improve the performance of construction projects in the South Africa construction industry. Data for this paper were obtained from both primary and secondary sources. For the primary data; a structured questionnaire was distributed to construction professionals both from the contracting companies, consultant offices & public owners sectors. Findings from the questionnaire surveys revealed that the measures to be taken for the improvement of the performance of construction projects in Gauteng, South Africa, include: proper project planning and scheduling, use of effective project management techniques, clear information and communication channels, adherence to construction drawings and specifications, proper material procurement, adequate planning, effective strategic planning, proper project implementation and management, frequent coordination between the construction team, use of appropriate construction methods, site management and supervision amongst others. The study contributes to the body of knowledge on the subject of measures to improve the performance of construction projects in the South Africa construction industry.

- Description: Abstract: Cost of poor quality (COPQ) in the construction industry is a serious problem that the industry is faced with, due to failure in preventing wastage and defects during construction work. The cost of poor quality remains hidden and eats up to 40% revenues of the construction enterprise. Hence, the study investigated the critical success factors that reduce poor quality in construction projects according to the perceptive of construction professionals in the Swaziland construction industry. This research adopted quantitative research and 50 useable questionnaires were used as an instrument tool for the study. Random sampling method was used to select the respondents in various construction companies. Cost of poor quality impact the construction industry of Swaziland’s and construction companies have to reserve funds for such occurrences, since poor quality cannot be tolerated and contractor have to rectify at own cost. Another challenge would be under-pricing the construction project and rectifying construction mistake it becomes a big problem for the contractor. Findings revealed that are a lot of success factors that can be used, it’s just a matter of the implementation of the success factors in the project. The role of the managers in construction projects is still under looked and therefore, this can be a problem if it is not attained to. The study revealed that are a lot of success factors such as the use of quality management system and the critical success factors can actually help eliminate poor quality in most construction projects of Swaziland. The implementation of quality management systems at the beginning of the project and encouraging team work in the project could assist construction projects.

- Description: Abstract: Construction is an important aspect of any economy and its effect cannot be over-emphasized. This research investigates the utilisation of lean construction (LC) tools in achieving project processes in the construction industry by identifying its drivers, barriers and how it can improve the delivery of construction projects. The data for the study was collected through detailed questionnaires which were administered on construction role players that are registered and with their professional bodies. The benefits of lean construction includes waste reduction, improved communication system, improved flow and productivity, customer focus and employee empowerment, sharing of knowledge. From the results of the analysis of data obtained from respondents, extensive use of unskilled labour, poor communication, human attitude towards change, lack of interest from clients, lack of client and supplier involvement, lack of long term commitment to change, lack of supply chain integration, lack of technical skills, and inadequate exposure to the requirements of lean construction, were some of the major barriers associated with the implementation of lean construction in the industry. The following lean construction principles that can be used to improve the delivery of construction projects were also identified: business process engineering, team work innovation, ongoing performance management, flow of activities and materials, continuous improvement, elimination of irrelevant activities, team and value management as well as continuous skill development. Itis necessary for organisations to implement the principle of lean construction and such need to be aware of the challenges associated with the practice. More so, there has to be an adequate level of awareness, commitment, knowledge and understanding of the underlying concepts of lean construction to enhance its successful implementation.

More so, there has to be an adequate level of awareness, commitment, knowledge and understanding of the underlying concepts of lean construction to enhance its successful implementation.

- Description: Abstract: Public-Private Partnerships (PPPs) play an important role in improving the quality of infrastructure service delivery in different countries. In the construction industry, PPPs contribute to skills transfer by the private sector to the public sector and achieving greater efficiency by reducing government bureaucracy and financial burdens. However, these partnerships have challenges that hinder the implementation and delivery of infrastructure. This research examines challenges encountered in the implementation of PPP in construction projects. The study is a literature review/ survey on the challenges faced with the implementation of public private partnership in improving infrastructure service delivery on projects. The study is conducted with reference to existing theoretical literature, published and unpublished research based on international context. However, the challenges specifically are based on literature in Swaziland to identify the challenges they face and the way forward. Other scholars'works were critically examinedtodeterminethe views on the subject. The research revealed that on the political level, there are high expectations with concerns that officials expertise to handle PPP projects are not sufficient, Private sector stakeholders were concerned about the possible dominance of foreign companies. Moreover, labour feared negative consequences for workers, and part of financial sector did not see enough opportunities for PPP in Swaziland. Lack of common understanding and coordination, insufficient planning capacity and structuring support were amongst the challenges faced by PPP in Swaziland.The study will assist the Swaziland Construction Industry in improving their services in terms of delivering construction project timeously since particular strategies can be developed to overcome the identified challenges.

- Description: Abstract: Implementation of construction works within the stipulated budget is vital for both the investor and the contractor. Yet construction projects, even those perfectly planned and organised, run the risk of cost overruns. Despite many tools supporting construction management, cost overruns keep occurring in construction projects. The present paper presents the findings of a survey aimed at identifying the most important causes and effects of cost overruns on construction projects in Gauteng - South Mrican construction industry. The data used in this paper were derived from both primary and secondary sources. The secondary data was collected via a detailed review of related literature. The primary data was collected through a well-structured questionnaire which was distributed to construction professionals, who include: Architects, quantity surveyors, civil engineers, construction mangers and project managers. Out of the 200 questionnaires sent out, 146 were received back representing a 73% response rate. Data received from the questionnaires was analysed using descriptive statistics procedures. Findings from the study revealed that inadequate planning, change in project design, poor project management, inadequate financial provision and inaccurate estimates were the major causes of cost overruns. Furthermore, the effects of cost overruns were identified to be construction project delays, increase in project cost due to extension on time, liability of companies to bad debt, project abandonment and company insolvency among others. The study contributes to the body of knowledge on the subject of the causes of construction project schedule overruns in Gauteng, South Africa.
