    Making a mark: Wits School of Construction Economics and Management and Its Contribution to the Construction and Property Fields
    (University of the Witwatersrand, Johannesburg, 2024) Laryea, Samuel; Smit-Stachowski, Alexandra; Mphuti, Bongi
    This book is a historical account on the Wits School of Construction Economics and Management, its contributions and impact in society, which is very significant and leaves a positive impression of academic and industry development, despite historical hurdles. It looks at the past, present, and future of the School in the broader context of South African history and the overall development of the university. The process of writing this book has been both challenging and exciting with interesting discoveries about the academic disciplines and the growth trajectory of the School. It was challenging uncovering information from various sources within the university and external sources. It has also been an interesting process learning about the rich history and contributions of a key School within the university to the South African and global society. This book chronicles the careers of some graduates of the School who served in the highest leadership and management roles, and made an indelible mark in the construction industry locally and internationally. The School’s graduates have made substantial contributions to the growth and advancement of the South African construction and property sectors and their respective statutory councils including the South African Council for Quantity Surveying Profession (SACQSP), South African Council for Project and Construction Management Professions (SACPCMP) and the South African Council for the Property Valuers Profession (SACPVP). The School’s graduates have also played leading roles in major construction firms that have built some of the iconic buildings in South Africa and other parts of the world. In recent years, many of the School’s graduates are increasingly being recruited by firms in Europe, Middle East, Australia, and the US, indicating the quality of their education and their value to employers and the global construction industry. Through a meticulous search through the Wits university archives and available published material, a huge amount of history and contributions of the School could be produced in this book. As these sources spoke their minds, many of their quotes are produced verbatim - so we can appreciate their wisdom. When gaps emerged in the historical chronology, we turned to those who studied and taught at Wits in the various phases of our Faculty. The Alumni and past Academics took time from their busy schedules as many are still instrumental in building our country, to answer several questions and share their fondest memories and what they believe is the state of the industry currently. The original 15-page document has grown and developed, as has the School, into a fully-fledged manuscript of interviews, yet-unheard-of stories and a vibrant and vital document, to be read and shared widely. The story arc includes the factual history of the School of Construction and Economic Management from birth until now, and is peppered with amusing anecdotes and pictures. Students’ awards were mentioned, where the information was available. This also serves to remember the inspiring academics including Professors Harry Bell-John, Geoff Pearse, Doug Calderwood, Ronnie Schloss and the lecturers who led our current leaders in the fields of quantity surveying, construction management, building sciences and property development, onto the path they have carved, so they can make a mark. This story is filled with chutzpah, grit, determination, humour and a few mishaps, but proves without a doubt that the time spent by students at Wits and SCEM has resulted in lasting friendships, business savvy and in professionals in the built environment who are making their mark across the country, the continent and the world. This is their story and the story of the School of Construction and Economic Management.

    Barriers to digitalization of procurement – a review
    (University of the Witwatersrand, Johannesburg, 2024-07) Ojo-Fafore, Elizabeth; Laryea, Samuel; Laryea, Samuel; Li, Baizhan; Essah, Emmanuel Adu; Mensah, Sarfo; Liu, Hong; Yao, Runming
    The concept of digital technology is making waves in the construction industry in developed countries; however, it is not the same story in other nations as there are several barriers militating the progress of adoption of the new concept. This study aims to investigate the barriers militating digitalization of procurement in Construction, to proffer solutions. This study investigated possible barriers affecting the implementation of digitalization of procurement using a descriptive literature review. Several past works were reviewed to fill the gaps and apply new methods that will enable the digitalization of procurement. The study discovered several barriers restraining the digitalization of Procurement, but there are three common barriers to the literature reviewed; insecurity, cost, and Lack of skilled expertise. This industry will bring overall improvements in project time, quality, cost, and safety standards as well as client requirements and satisfaction. This research paper is of the view that digitalization will increase productivity and the competitive advantage in the Construction industry. In conclusion, there is a need to prioritize investment in digital tools and technology to have ease of adoption of procurement digitalization.

    Perceptions of tender document quality and its impact on construction estimates
    (University of the Witwatersrand, Johannesburg, 2024-07) Nezambe, Bruce; Laryea, Samuel; Govender, Neil; Laryea, Samuel; Li, Baizhan; Essah, Emmanuel Adu; Mensah, Sarfo; Liu, Hong; Yao, Runming
    Construction experts have noted the persistent concern about the quality of tender documents and its impact on the construction sector. Poor specification writing continues to be a weak link in the information chain that degrades the quality of tender documents and causes disputes, particularly in a competitive market where construction professionals strictly interpret the documents to prepare a competitive bid. The impact of tender document quality on the accuracy of project estimates is assessed to determine the determinants of good tender-quality documents. Additionally, interventions that can be implemented to improve tender document quality and the implications of poor tender document quality were also analyzed. Qualitative data was collected from construction professionals using an interview. Data was analyzed by Atlas-ti using thematic analysis where six key themes were extracted. The study concluded that poor quality tender documents compromise the accuracy of project estimates and delivery of projects within the South African construction industry. The consequences of poor tender document quality included reduced project profitability, incomplete projects, project termination due to funding issues, misunderstanding of boundaries, misalignment of the programme, increased costs and a negative impact on construction estimates.

    Bibliometric review of social value in construction literature
    (University of the Witwatersrand, Johannesburg, 2024-07) Laryea, Samuel; Kwasafo, Oscar Kwame; Mensah, Sarfo; Laryea, Samuel; Li, Baizhan; Essah, Emmanuel Adu; Mensah, Sarfo; Liu, Hong; Yao, Runming
    The construction industry plays a leading role in the provision of infrastructure projects that promote not only the primary objectives for which a project is intended but also the secondary objectives which relate to wider socio-economic development and social value aspects, as shown in the International Organization for Standardization (ISO 10845…2022) 10845 family of standards for construction procurement. While most papers in the construction literature have focused on the primary objectives of infrastructure projects such as costs, time, and quality, relatively little attention has been focused on the secondary objective aspects like economic, environmental, and social sustainability objectives. There has been an increasing focus on the social value aspects of infrastructure projects in recent years. This trend seems likely to increase and directions for future research can be generated from examining the current literature. This paper examines 78 articles relating to social value in construction to explore current understanding and key emerging themes in this area. The 78 articles were identified through a systematic search in Scopus and Google Scholar, then analysed using temporal co-word analysis to generate four key bibliometric themes: social sustainability, social procurement, social value, and employment. Two preliminary conclusions are presented from the bibliometric review. First, while using the ‘social value’ terminology may show this as a relatively new concept flowing from the social sustainability discourse, earlier studies and practices in this area precede the ‘social value’ terminology and appropriate linkages to earlier knowledge should be properly established. Secondly, different terminologies are used to refer to the same concept, creating duplication and significant overlaps across the different terminologies. It would be necessary to consolidate and align the various terminologies for consistency.
