New code of estimating practice

The Code sets out guidelines and best practice for estimating construction works. In Section 1 it embraces the principles, theory, and background to estimating. In Section 2 it considers the process and practice of estimating, setting out how materials, labour, plant and equipment, and overheads can be calculated. Construction has become more complex, but the need to have a reliable and robust estimating systems remains at the core of the industry. New pressures and responsibilities require attention to how work will be undertaken in a highly regulated and controlled industry

Stakeholders' role in improving Ghana's construction safety

Health and safety (H&S) management has traditionally been the responsibility of the contractor. Most often, contractors are blamed for the accidents and other ill health that occur on their construction sites. H&S performance is, however, enhanced when there is effective collaboration between those involved in the construction process. This paper therefore explores the role of stakeholders in promoting construction H&S in Ghana through public works procurement. The four main stakeholders identified and evaluated in this study are the government, the client (employer), the contractor and the employee(s). Seven interviewees (comprising procurement managers, consultants and quantity surveyors) from public institutions in Ghana participated in the research. Data were collected using semi-structured interviews and were thematically analysed. Results indicate a conflict in the perceived functions and relation of these stakeholders in the construction process. To address the constraint to improving construction H&S, certain recommendations are offered. These include the identification of specific individuals responsible for supervision and employee training, the development of H&S policies by the government and contracts that clearly outline the contractual obligations of all parties involved. Additionally, the specific roles and involvements of other stakeholders in the procurement process in improving construction H&S are also outlined

Collective Decision-Making with 4D BIM: Collaboration Group Persona Study

International audience4D BIM assures more detailed costs and error control, whilst also improving scheduling and coordination. It relies on interoperability and high levels of collaboration, which have increased the value of collective competen-cies. In addition to the competencies, the collaboration group internal influences and subordination must be considered as well. While the knowledge and com-petencies of each and every individual team member are important, BIM allows the team to use the entire set of collective knowledge, skills and competencies, which are the key feature for advanced digital management of the AEC project. Such management requires a successful implementation and efficient use of 4D or nD BIM. This study proposes to summarize collaboration personae of AEC project collaborative groups, and to associate the collective knowledge and competencies to 4D BIM uses. Further, it will be completed with interviews on current 4D practices with BIM professionals. Moreover, through this research, we continue to progress towards a new 4D collective decision-making support proposition

Heritage organisations and condition surveys

Purpose This paper aims to examine the role and purpose of condition surveys used by heritage organisations. Design/methodology/approach The study is based on the analysis of questionnaires and interviews with a range of leading heritage organisations in the UK. Findings The research suggests that the management of maintenance, and specifically the implementation of condition surveys, lacked an explicit underlying strategic basis. The strategic opportunities implied by the development of conservation planning methodologies had not been translated into management practice and had not impacted on the implementation of condition surveys. Practical implications Further investigation into the organisational and process barriers to utilising conservation plans in developing integrated management of the built cultural heritage is needed. Originality/value This paper will be of use to practitioners and academics interested in appropriate and sustainable maintenance and management of the built cultural heritage. © 2005, Emerald Group Publishing Limite
