The hypothesis states that the standard South African forms of contract for building work have evolved to promote control through construction project management processes. The South African suites of contracts are reviewed against the project management office’s (PMO) main focus areas for best practices. This endeavours to establish the conduciveness to facilitate good project management functions on building projects. The main clauses of each contract are compared to the construction project management knowledge areas. Two contracts are reviewed, and it is established that both contracts (General Conditions of Contract for Du Plessis • Facilitation of construction project management... 121 Construction Work 2015 and the Joint Building Contracts Committee’s (JBCC) Principal Building Agreement Edition 6.2) provide the employer’s agent (EA) the necessary authority to manage the project for its intended purpose. It became apparent that the contracts may allow certain project management functions to be implemented by placing different emphases on different aspects of the contract. Due to the complexity and uniqueness of each project, the number of standard contract conditions governing a contract are limited. A strong project management function must take place during the planning phases. The contract used influences the way in which the project management functions are applied during the project life cycle (PLC). Thus, the project manager must have an intimate knowledge of the content of the contract in order to implement the desired construction project management functions, as required during each of the PLC stages.","PeriodicalId":42571,"journal":{"name":"Acta Structilia","volume":" ","pages":""},"PeriodicalIF":0.7,"publicationDate":"2019-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47404711","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Disputes can be resolved through litigation, but this is often costly and time consuming. A study in 2012 reveals that, among others, arbitration, mediation, negotiation and adjudi cation are different forms of Alternative Dispute-Resolution (ADR) methods preferred and used to resolve disputes in the built environment. This article professionals and candidates to determine the implementation of ADR methods. This questionnaire was distrusted by the Chief Operations Officer, Mrs Barbara van Stade to the aforementioned SACAP database. The survey response amounted to 396 participating architectural practitioners, resulting in 2.91% of registered architectural professionals and candidates in the South African built environment. Consequently, this is the most comprehensive study on the preferred use of ADR methods by architectural practitioners in the built environment of South Africa. This study specifically focuses on architectural practitioners who have been involved in settling disputes between the period of 2012 to 2016. The findings reveal a shifting preference in ADR methods used since what the previous study found in 2012. Although previous studies indicate adjudication as the preferred method to resolve disputes, the data reveals that architectural practitioners increasingly make use of negotiation, followed by mediation and then arbitration. This study identifies current ADR trends, and provides a perspective on the future development of ADR mechanisms for architectural professionals in the South African built environment.","PeriodicalId":42571,"journal":{"name":"Acta Structilia","volume":" ","pages":""},"PeriodicalIF":0.7,"publicationDate":"2019-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44506209","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hardly any effort is made on to how sustain quality in road-project construction through suitable construction strategy in local governments. This article aims to analyse and examine the quality of road-construction projects built by SMEs contractors in Mopani District Municipality, South Africa. The article follows a quantitative survey approach in which a three-section questionnaire was administered to 160 purposively selected roadbuilding practitioners in South African construction SMEs. The questionnaire was structured into three parts, which sought the participants’ profile, identified the quality assurance practices (QAPs) incorporated in the construction SMEs’ road-building programmes, and identified the factors that negatively Acta Structilia 2019: 26(1) 2 influence the implementation of QA processes. Data was analysed using the Statistical Package for the Social Sciences (SPSS) version 23. Descriptive statistics was used to determine the reliability of the various constructs, mean scores, and standard deviations. The empirical findings established eight QAPs that were reliable and valid for implementation processes that can control or minimise their causes of poor quality in projects undertaken by construction SMEs’ level of skill acquisition. These are: project planning and control techniques; project construction design; process implementation and process improvement; financial management; organisational structures; involvement of people, as well as quality standards and measurements. The eight factors attained high Cronbach Alpha values above the recommended 0.70, which indicates high internal consistencies among the sub-scales. This article is significant in that project managers working in similar environments may use the results of this study either as diagnostic tools or as a reference benchmark for strategic interventions in solving construction projects-related problems. The researchers also recommend that these practices are for QA in construction projects undertaken by SMEs in South Africa.","PeriodicalId":42571,"journal":{"name":"Acta Structilia","volume":" ","pages":""},"PeriodicalIF":0.7,"publicationDate":"2019-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45602894","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This article examines the factors that influence the performance of safety management programmes in the Ghanaian Construction Industry. The objectives set to achieve this aim include identifying the safety elements incorporated in the safety programmes of construction firms, and determining the factors that negatively influence the performance of such elements. For objectivity, a quantitative survey was conducted among safety managers of 60 D1 building construction firms located in the Kumasi and Greater Accra regions of Ghana. The questionnaire was structured into three parts, which sought the respondents’ profile, identified the safety elements incorporated in the firms’ safety programmes, and identified the factors that negatively influence the performance of the safety elements. Following a detailed literature review, the respondents were asked to rate 13 elements and 17 factors on a Likert scale. Data was analysed using the Statistical Package for Social Sciences (SPSS) Version 22. In addition to determining the reliability of the various constructs, the MSs, modes and standard deviations were obtained. The findings revealed that all of the 13 elements were incorporated in the firms’ safety programmes. The key elements identified include ‘providing safety managers on site’; ‘providing written and comprehensive safety and health plans’; ‘introducing project-specific training and regular safety meetings’; ‘providing safety and health orientation training’, and ‘involving employees in safety and evaluation’. The findings further revealed that 16 of the 17 factors negatively influence the performance of the firms’ safety programmes. The identified factors were, among others, ‘insufficient communication of safety programmes’; ‘lack of workers’ self-protection and awareness’; ‘contractors ignoring safety, due to the time pressures of the project schedule’; ‘poor personal attitudes towards safety’, and ‘ineffective laws and lack of enforcement’. Findings from this study should be useful to construction practitioners seeking to improve the safety records of their firms.

Cloete","doi":"10.18820/24150487/AS25I2.1","DOIUrl":"https://doi.org/10.18820/24150487/AS25I2.1","url":null,"abstract":"The current implementation of Building Information Modelling (BIM) by construction professionals in the Kenyan construction industry is an area of concern. BIM is increasingly being applied worldwide to improve communication between project stakeholders, visualization of design, detect potential clashes, reduced redesign during project implementation, improve design quality, reduce costs, and improve the rate of return for projects. However, the application of BIM in the Kenyan construction industry is still lagging, resulting in poor co-ordination of information among construction project stakeholders. This study determines the current state of BIM application, the benefits of BIM application and the BIM application barriers in Kenya. A quantitative research approach was used and data was collected, using an online questionnaire survey from 310 registered construction professionals selected by stratified sampling. The benefits and barriers factors that influence BIM application in Kenya were rated and set as the independent variables with ‘years of experience’ and ‘total completed projects’ as the dependent variables. The data was analysed using the Statistical Package for the Social Sciences (SPSS) version 24. Principal components analysis (PCA) was used to extract the main factors for benefits and barriers of BIM implementation. Chi-square tests were used to determine relationships between independent and dependent variables. Improved communication was ranked as the most important BIM benefit, while the high cost of buying and updating software was ranked as the main barrier to the application of BIM. Based on the results of the study, improved design quality is influenced by the number of years of experience one has in the building construction industry. The number of projects undertaken by a company using BIM in any capacity has an influence on greater productivity, due to easy retrieval of information. It is recommended that BIM training should be undertaken by software vendors in vocational and tertiary institutions as well as in construction firms. In addition, the government should formulate policies and standards to support the use of BIM. This study adds to the body of knowledge about BIM application in Nairobi, Kenya that is beneficial to developers, architects, engineers, quantity surveyors, project managers, contractors, and facility managers.
