This article identifies how project life cycle characteristics and automation and robotic technologies influence the sustainability of public-private partnership (PPP) infrastructure projects. The result of the article is a model of how public and private collaborations can leverage technology and project organization to make infrastructure more sustainable. Based on a comprehensive literature review, the model subdivides sustainability into engineering, project management, environmental, social, and economic dimensions. Engineering sustainability concerns the applicability of technologies to infrastructure PPP sustainability. The project management sustainability is decisive for ultimately creating environmental, social and economic sustainability within and beyond infrastructure PPP projects. The model identifies that the procurement phase is of particular importance for sustainable infrastructure PPPs. Successful sustainable infrastructure procurement likely includes such factors as increased transparency, participation, and stable, capable project alliances with a shared vision and clear goals. The model also identifies that, throughout the whole project life cycle, actions in the form of collaboration, experimentation and platformization promote sustainability. The findings in this article add to the understanding of how transformation toward increased sustainability can be achieved by individual organizations, their network, and ecosystems of public, private and civic actors.
<p>The construction industry is essentially determined by digital transformation and an increasingly complex market environment. Project controlling and monitoring is of high importance for construction site activities to achieve the project goals. Digital planning and recording methods make it possible to identify deviations at an early stage and to ensure the profitability of the project. To discuss the current practice of construction performance measurement as well as digital approaches in this domain, a qualitative study was carried out. The results of this empirical analysis examine the status quo of the construction performance measurement in civil engineering companies to illustrate the currently used methods and trends. Findings for the future use of digital planning and recording methods were obtained from the investigation. Based on empirical hypotheses, recommendations for action as well as for an improved process model are given.</p>
Contemporary workspace and office concepts are part of many major commercial real estate projects and have been continuously developed over many years. With a rising awareness for sustainable development, workspace and office concepts are increasingly being considered in terms of their environmental performance. Sustainable design strategies therefore traditionally differentiate between efficiency, consistency, and sufficiency, whereas the latter approach is the least explored in the construction industry. Sufficiency can be described by a user behaviour characterized by frugality and modesty, as opposed to wasteful consumption. Moreover, the strategy of sufficiency is linked to a high and critical awareness of using natural resources and environmental impacts which also affects the built environment. The aim of this paper is therefore to combine these two subject areas in a structured way and derive potentials for the sufficient development of office concepts. Based on a literature review in the field of workspace design and flexible workplace management, design features of office spaces are conceived and compiled according to planning aspects in office concepts based on employee needs. Another literature review in the field of sufficiency in the building sector provides the corresponding structure for the considered sufficiency strategies. Sufficiency measures follow recurring principles for the reduction of resource consumption. Essential principles of impact are identified and presented in this paper. The investigated topic areas are compiled together in a logical model based on a developed mapping framework. This forms the basis for defining sufficient measures that can be derived to sufficiency strategies in the project development of office buildings. The basis of all measures is to strive for a minimum level of resource consumption that is necessary to satisfy the needs of the users and that is considered valuable by them, following the basic idea of the sufficiency approach. The results are validated using an office building in the planning stage. The paper leads to a common understanding and structuring of design features of future office spaces and their environmental impact. Furthermore, the approach provides guidance for concepts on how design features can be considered regarding sufficiency strategies.
