While smart maintenance is gaining popularity in professional engineering and construction management practice, little is known about the dimensions of its maturity. It is assumed that the complex networked environment of maintenance and the rise of data-driven methodologies require a different perspective on maintenance. This paper identifies maturity dimensions for smart maintenance of constructed assets that can be measured. A research design based on two opposite cases is used and data from multiple sources is collected in four embedded case studies in corporate facility management organizations. Through coding data in several cross-case analyses, a maturity framework is designed that is validated through expert consultation. The proposed smart maintenance maturity framework includes technological dimensions (e.g., tracking and tracing) as well as behavioral dimensions (e.g., culture). It presents a new and encompassing theoretical perspective on client leadership in digital construction, integrating innovation in both construction and maintenance supply networks.
The impact of the construction industry on the natural environment is severe, natural areas are changedinto predominantly hard solid surfaces, the energy use in the built environment is high and the industryputs huge claims on materials.

A large share of urban freight in cities is related to construction works. Construction is required to create attractive, sustainable and economically viable cities. When activities at and around construction sites are not managed effectively, they can have a negative impact on the cities liveability. Construction companies implementing logistics concepts show a reduction of logistic costs, less congestion around the sites and improved productivity and safety. The client initially sets the ‘ground rules’ for construction in the tendering process. This paper explores how tendering for construction projects can support sustainable urban construction logistics. We explore the potential for tendering construction projects, by both public and private clients, for sustainable urban construction logistics and we present a conceptual framework for specifying ‘logistics quality’ as a quality criterion for EMAT (Economically Most Advantageous Tender). Our exploration results in questions for further research in tendering for sustainable urban construction logistics.
The research proposal aims to improve the design and verification process for coastal protection works. With global sea levels rising, the Netherlands, in particular, faces the challenge of protecting its coastline from potential flooding. Four strategies for coastal protection are recognized: protection-closed (dikes, dams, dunes), protection-open (storm surge barriers), advancing the coastline (beach suppletion, reclamation), and accommodation through "living with water" concepts. The construction process of coastal protection works involves collaboration between the client and contractors. Different roles, such as project management, project control, stakeholder management, technical management, and contract management, work together to ensure the project's success. The design and verification process is crucial in coastal protection projects. The contract may include functional requirements or detailed design specifications. Design drawings with tolerances are created before construction begins. During construction and final verification, the design is measured using survey data. The accuracy of the measurement techniques used can impact the construction process and may lead to contractual issues if not properly planned. The problem addressed in the research proposal is the lack of a comprehensive and consistent process for defining and verifying design specifications in coastal protection projects. Existing documents focus on specific aspects of the process but do not provide a holistic approach. The research aims to improve the definition and verification of design specifications through a systematic review of contractual parameters and survey methods. It seeks to reduce potential claims, improve safety, enhance the competitiveness of maritime construction companies, and decrease time spent on contractual discussions. The research will have several outcomes, including a body of knowledge describing existing and best practices, a set of best practices and recommendations for verifying specific design parameters, and supporting documents such as algorithms for verification.
The postdoc candidate, Sondos Saad, will strengthen connections between research groups Asset Management(AM), Data Science(DS) and Civil Engineering bachelor programme(CE) of HZ. The proposed research aims at deepening the knowledge about the complex multidisciplinary performance deterioration prediction of turbomachinery to optimize cleaning costs, decrease failure risk and promote the efficient use of water &energy resources. It targets the key challenges faced by industries, oil &gas refineries, utility companies in the adoption of circular maintenance. The study of AM is already part of CE curriculum, but the ambition of this postdoc is that also AM principles are applied and visible. Therefore, from the first year of the programme, the postdoc will develop an AM material science line and will facilitate applied research experiences for students, in collaboration with engineering companies, operation &maintenance contractors and governmental bodies. Consequently, a new generation of efficient sustainability sensitive civil engineers could be trained, as the labour market requires. The subject is broad and relevant for the future of our built environment being more sustainable with less CO2 footprint, with possible connections with other fields of study, such as Engineering, Economics &Chemistry. The project is also strongly contributing to the goals of the National Science Agenda(NWA), in themes of “Circulaire economie en grondstoffenefficiëntie”,”Meten en detecteren: altijd, alles en overall” &”Smart Industry”. The final products will be a framework for data-driven AM to determine and quantify key parameters of degradation in performance for predictive AM strategies, for the application as a diagnostic decision-support toolbox for optimizing cleaning &maintenance; a portfolio of applications &examples; and a new continuous learning line about AM within CE curriculum. The postdoc will be mentored and supervised by the Lector of AM research group and by the study programme coordinator(SPC). The personnel policy and job function series of HZ facilitates the development opportunity.
Er wordt continu ‘reuzenarbeid’ verricht in het rivierengebied in het teken van hoogwaterbescherming, vaarwegbeheer, natuurontwikkeling en delfstoffenwinning. Bij veel van deze rivierprojecten maakt grondverzet het grootste deel uit. Het is onder andere bepalend voor de kosten, de CO2-footprint en de omgevingshinder van dergelijke projecten, en de ruimtelijke kwaliteit van het rivierlandschap. Slim omgaan met grond is daarom een sleutelfactor van duurzaam rivierbeheer. Het onderwerp heeft daarom een prominente plek in verschillende kennis- en innovatieagenda’s, zoals de KIA Landbouw, Voedsel en Water, de KIA Circulaire Economie, en de KIA van het Hoogwaterbeschermingsprogramma. Deze articuleren een behoefte aan praktijkgericht onderzoek dat bijdraagt aan verduurzaming en kostenreductie van grondverzet, zodat grondverzet in 2030 energieneutraal is, de kosten per m3 tussen 2020 en 2030 aanzienlijk gedaald zijn en dat er in 2030 een gezonde slibeconomie is voor circulair materiaalgebruik. Desondanks moet er nog heel wat water door de Rijn voordat bovenstaande ambities in de praktijk kunnen worden gehaald. Het doel van dit project is om praktische inzichten en tools voor duurzaam grondmanagement in riviergebieden te ontwikkelen. Een consortium van 22 partijen (publiek, privaat, kennis) zal onder leiding van HAN lectoraat Sustainable River Management praktijkgericht onderzoek doen ter ondersteuning van technisch managers, ontwerpers, risicomanagers, projectmanagers en beheerders van dijken en uiterwaarden. Door middel van o.a. materiaalonderzoek, ontwerpend onderzoek en evaluaties worden praktische handvatten ontwikkeld voor realisatiestrategieën voor grondstoffenwinning volgens het DNA van de rivier, en het bruikbaar maken van sediment en gebiedseigen grond voor toepassing in de dijkenbouw. Bovendien worden verbeterde werkwijzen en tools ontwikkeld voor het op riviertakniveau afstemmen van vraag en aanbod van delfstoffen in natuur- en dijkversterkingsprojecten in het rivierengebied. Hiermee levert het project een concrete bijdrage aan de invulling van het Grondstoffenakkoord en het Rijksprogramma ‘Nederland Circulair in 2050’.
