From the article: Abstract. This exploratory and conceptual article sets out to research what arguments and possibilities for experimentation in construction exists and if experimentation can contribute towards more innovative construction as a whole. Traditional, -western- construction is very conservative and regional, often following a traditional and linear design process, which focuses on front-loaded cost savings and repetitive efficiency, rather than securing market position through innovation. Thus becoming a hindrance for the development of the sector as a whole. Exploring the effects of using the, in other design-sectors commonly and successfully practiced, “four-phased iterative method” in architectural construction could be the start of transforming the conservative construction industry towards a more innovative construction industry. The goal of this research is to find whether the proposed strategy would indeed result in a higher learning curve and more innovation during the - architectural- process. Preliminary research indicates that there is argumentation for a more experimental approach to construction.

In recent years, the number of publications on innovation in the construction industry has increased. Many of these documents address qualitative issues, e.g. policies for innovation and present case studies. A more quantitative approach is taken in this paper, which is the continuation of a previous study. It focuses on main types and sources of innovation in the construction industry, and includes an analysis of 55 years of publications in two leading Dutch professional journals. The results show a recent increase in innovation, with two-thirds of innovations coming out of supplying industries. Construction companies contribute mainly in process innovations. Innovation in construction remains to be technology- rather than market-driven. Regulations have a surprising impact, as over one-third of all counted new innovations are related to new regulations.

From the article: "Project execution in the construction industry faces major challenges, e.g. difficulty in coordination and cooperation. Operational procurement during project execution is no exception. In this paper we construct a maturity model, based on earlier work, consisting of six dimensions (goal, control, process, organization, information, technology) and five maturity stages (transactional-oriented, commercial-oriented, coordination, internal-optimized, external-optimized). The model can be used to determine the level of procurement maturity for each of the dimensions, and for the determination of a strategy for growth in the construction industry. With input from a major construction firm in the Netherlands, through simulating tooling, the model is evaluated for its contribution to growth in operational excellence. Results of the simulation show support for a relation between maturity growth and increased operational excellence."

Construction and Demolition Waste (CDW) is the main driver of resource consumption and waste generation in Europe. Although most European countries achieved 70% recovery rate of CDW, the majority is used for backfilling. Therefore, opportunities for Circular Economy (CE) practices in CDW management are underexploited. This research identifies the innovative practices, barriers, and enablers for developing tailored-made designs of Urban Resource Centre (URC) for managing CDWs in four European cities namely Riga, Tartu, Kavala, and Barcelona. Qualitative methods using multiple case studies were used to draw generalizations from cases. Data was collected from reports and interviews with different stakeholders, and a validation workshop for designing URC of each city. Current innovative practices include recycling and upcycling of CDWs; use of green points, exchange platforms, and waste management apps; repair cafés; selective demolition; and (pilot) initiatives on resource centers that function as material exchange point, recycling center, workstation for repair and creative ideas, and prototyping hub, among others. The identified barriers and enablers can be categorized as governmental, market, and individual factors. First, local governments (municipalities) play a key role for facilitating CDW management via both support such as provision of subsidies, green procurement, and mandatory waste sorting, and through strict regulatory requirements. Second, URCs must be locally rooted with inclusion of citizens, grass roots initiatives, and schools/universities to increase community acceptance, awareness, and education on CDW management. Third, partnerships with local stakeholders, such as repair cafes, waste management companies, and local NGOs, is needed to operate the URCs both in short- and long-terms. And fourth, the creation of niche markets such as linking localism (e.g. locally crafted CE stores) and supplying to businesses in need of CDWs, can support the operation of URCs. The identified barriers and enablers can help further improve the design of URCs for each city.

Dealing with and maintaining high-quality standards in the design and construction phases is challenging, especially for on-site construction. Issues like improper implementation of building components and poor communication can widen the gap between design specifications and actual conditions. To prevent this, particularly for energy-efficient buildings, it is vital to develop resilient, sustainable strategies. These should optimize resource use, minimize environmental impact, and enhance livability, contributing to carbon neutrality by 2050 and climate change mitigation. Traditional post-occupancy evaluations, which identify defects after construction, are impractical for addressing energy performance gaps. A new, real-time inspection approach is necessary throughout the construction process. This paper suggests an innovative guideline for prefabricated buildings, emphasizing digital ‘self-instruction’ and ‘self-inspection’. These procedures ensure activities impacting quality adhere to specific instructions, drawings, and 3D models, incorporating the relevant acceptance criteria to verify completion. This methodology, promoting alignment with planned energy-efficient features, is supported by BIM-based software and Augmented Reality (AR) tools, embodying Industry 4.0 principles. BIM (Building Information Modeling) and AR bridge the gap between virtual design and actual construction, improving stakeholder communication and enabling real-time monitoring and adjustments. This integration fosters accuracy and efficiency, which are key for energy-efficient and nearly zero-energy buildings, marking a shift towards a more precise, collaborative, and environmentally sensible construction industry.

Since the film of Al Gore An inconvenient truth, sustainability stands high on the national agenda of most countries. Concern for the environment is one of the main reasons in combination with opportunities to innovate. In general, innovation and entrepreneurship are important in the realm of national economies because they hold the key to the continuity and growth of companies (e.g. Hage, 1999; Cooper, 1987; Van de Ven, 2007) and economic growth within a country. It is therefore obvious that national governments are investing money to enable and improve innovation management and entrepreneurial behaviour within organizations with sustainability in mind. Policy measures are aimed at reduction of carbon dioxide emission, waste management and alternative use of energy sources and materials. In line with these measures companies are urged to integrate sustainability in their business processes and search for innovative sustainable solutions. While on a national level policy measures towards a more sustainable society are defined, enterprises - and especially small and medium sized companies - lag behind and fail in incorporating these measures appropriately in their day-to day business. As a result research for sustainability has become an important driver for innovation. Within the Centre for Innovation and Entrepreneurship (CI&E) at The Hague University of Applied Sciences we have taken the initiative to develop an innovation and research program for the construction industry to help small and medium sized companies (SME's) integrate sustainability in their business processes, while simultaneously professionalizing students and lecturers. This paper is part of ongoing research among 40 companies in the region of South-Holland. The companies are mostly SME's varying from very small (6 employees) to middle-sized (more than 100). According to Rennings (2000) while innovation processes toward sustainable development have received increasing attention during the past years, theoretical and methodological approaches to analyse these processes are poorly developed. This paper describes a theoretical approach developed at our university's Centre for Innovation and Entrepreneurship, which combines education and research. It is an inductive approach that departs from real-life problems encountered by companies, and is aimed at developing a model that supports companies in integrating sustainability in their business and innovation processes. We describe the experiences so far with a number of companies in the construction industry, which participate in the innovation and research program described above and the barriers they encounter. Our sustainable program is centred on four themes: cradle-to-cradle, social corporate responsibility, climateneutral construction and sustainability and customer orientation in the building process. It is an exploratory research in which students and undergraduates are involved under the supervision of a lecturer as senior researcher of this program. Through an in-depth analysis of the companies, participant observation and indepth interviews with the owners/directors of the companies, experts and prominent sustainable trendsetters, insight is gained in innovation processes towards sustainable development. Preliminary conclusions show that on a company level one of the main bottlenecks is the dilemma posed by the need for profit for the continuity of a company, while taking into account people and planet. The main bottleneck is however the inability of companies to translate policy measures into strategy and operations. This paper is set up as follows. In section 2 we give an account of European and Dutch policy measures geared at stimulating sustainability in a business context and especially the building and construction industry. In section 3 an overview is given of the economic importance and characteristics of the Dutch building and construction industry and the problems in this sector. These problems are offset against the opportunity of sustainability as a strategic option for SME's in this sector. In section 4 the innovation and research program developed at the CI&E is introduced in the context of the main research question. Following that in section 5, methodological choices are addressed and the research design is presented. We finalize this paper in section 6 with our conclusions and recommendations for further research.

Educational institutions and vocational practices need to collaborate to design learning environments that meet current-day societal demands and support the development of learners’ vocational competence. Integration of learning experiences across contexts can be facilitated by intentionally structured learning environments at the boundary of school and work. Such learning environments are co-constructed by educational institutions and vocational practices. However, co-construction is challenged by differences between the practices of school and work, which can lead to discontinuities across the school–work boundary. More understanding is needed about the nature of these discontinuities and about design considerations to counterbalance these discontinuities. Studies on the co-construction of learning environments are scarce, especially studies from the perspective of representatives of work practice. Therefore, the present study explores design considerations for co-construction through the lens of vocational practice. The study reveals a variety of discontinuities related to the designable elements of learning environments (i.e. epistemic, spatial, instrumental, temporal, and social elements). The findings help to improve understanding of design strategies for counterbalancing discontinuities at the interpersonal and institutional levels of the learning environment. The findings confirm that work practice has a different orientation than school practice since there is a stronger focus on productivity and on the quality of the services provided. However, various strategies for co-construction also seem to take into account the mutually beneficial learning potential of the school–work boundary.

The research concerned semi-dyadic relations in SMEs and large companies that managed innovative suppliers in New Zealand construction supply chains. It explored effects of (independent) company variables on (mediating) procurement management variables, and also the effects of these variable types on (dependent) procurement performance variables when managing innovative suppliers.Exploratory interviews (N=5) revealed that innovation procurement seemed professional and logical within their contexts.Survey I (N=112) revealed that most case companies followed a product leadership strategy, and were equally entrepreneurial to innovative customers and innovative suppliers. They were innovative and gave innovative suppliers a dominant innovation role. They seemed to prefer radical innovations less than incremental innovations, but still somewhat more than New Zealand averages. Companies had slight preferences for new, small, or foreign suppliers for radical innovations. Innovations with supplier interactions were more beneficial to the company and the natural environment, than innovations without supplier interactions. Higher company innovation-benefits could equal higher environmental innovation-benefits. This profile differed from the profile of average companies in the construction supply chain.Survey I found weak correlations among output performance variables and process or proxy performance variables.Dependent (procurement and performance) variables were affected differently. Conversely, independent (company and procurement) variables had different effects.Different from extant literature, Survey I found limited statistically-significant effects of company variables on procurement management variables, and of these two variable types on performance. A minority (41%) of company variables affected procurement variables; only two company variables (13%) affected performance; a minority (40%) of procurement variables affected performance.Product leadership and NPD/innovation experience affected performance. Moreover, trust, lifestyle strategies and survival strategies affected procurement variables. Conversely, 27% of performance variables (satisfaction on marketing & sales; benefits for the natural environment) and 30% of procurement variables (entrepreneurial orientation with innovative suppliers, relation intensity with manufacturers, and small vs large suppliers for radical innovations) responded stronger on some company variables. Company size (<99 versus >250 staff) had little effects.Innovating, opportunity-seeking and trust towards innovative suppliers, and relation intensity with innovative service providers had highest effects on performance. Conversely, 46% of the performance variables (satisfaction with innovative suppliers, benefits for natural environment and company) responded stronger on innovating, opportunities-seeking and trust variables.Survey II (N=33) identified 12 procurement best-practices that respondents used for specific supplier or innovation types.Causality should be treated cautiously. Findings reflected the inconclusive results from extant literature. The research provided a nuanced and varied understanding on management of innovative suppliers, on the effects of entrepreneurial orientation to innovative suppliers, on the limited effects of company size, on the complex relations between various performance measures, and on entrepreneurship as a theoretical lens in innovation procurement. Companies had several options on how they managed their innovative suppliers. Additionally, the company characteristics and context of in this nascent research domain could be more important than commonly assumed from extant research.

from the paper: "This paper presents a research endeavouring to model site work in a 4D BIM model. Next simulations are performed with this model in 5 scenarios including specific interventions in work organisation, notably changing positons of facilities for site workers. A case study has been done in a construction project in the Netherlands. The research has showed the possibility to model time use of site workers in 4D BIM. Next the research has showed potential to perform and calculate specific interventions in the model, and prospect realistic changes in productive time use as a result."
