This dataset provides a comprehensive compilation of Ground Penetrating Radar (GPR) surveys across 125 utility surveying activities in the Netherlands. The dataset details the specific use of GPR in each authentic real-life utility surveying activity, whether employed independently or as a complementary tool alongside existing surveying methods, wi...

Ground Penetrating Radar (GPR) is an electromagnetic inspection method that can explore the underground environment and it is commonly used to locate targets that have a circular cross-section, such as pipelines. Therefore, the appearance of such targets in GPR survey results (radargrams) has received a lot of attention in the literature. However,...

Sinkholes nabij ondergrondse infrastructuur komen incidenteel voor, maar kunnen een impact hebben op zowel het functioneren van de infrastructuur als ook de veiligheid en overlast in de openbare ruimte op maaiveld. Er is tot op heden beperkte informatie over de rol en omvang van sinkholes onder het wegdek. Het doel van deze studie is daarom het ide...

To identify voids around underground concrete sewer pipes, a few studies have introduced conducting in-pipe Ground Penetrating Radar (GPR) inspection systems along the pipes. However, less research has focused on studying the implications of emission, propagation, and reception of electromagnetic waves in the enclosed environment of sewer pipes and...

Design science studies provide a means to understand how context-dependent digital artefacts land in the construction management application environment. Design sciences produce contextualized knowledge and technical insights instead of generic abstract management claims. The approach is, however, not very common in CM research. To explore its suit...

Many scholars have denounced innovation in construction as problematic. Existing work processes and routines may resist or even block the adoption of new technologies. Unravelling how new technology interferes with organizational processes could facilitate a more mindful innovation process. This study, therefore, conceptualizes how technology pilot...

On-equipment and practical sessions are indispensable part of construction equipment training. Currently, however, instructors receive very little to no technological support during these practical sessions, where they have to observe and provide feedback to multiple trainees concurrently. Therefore, the objective of this research is to develop a v...

The generation and use of 3D images and visualizations through remote sensing, Building Information Modeling, and Augmented Reality technologies, have come to play a significant role in construction engineering practice. Although these technologies are promising, their potential can be misjudged when potential end-users are unaware of key assumptio...

This study uses the utility construction sector as a case to build the argument that specialisation, transience and price competition impede the reliable functioning of supply chains. These three contracting qualities obstruct the establishment of antecedents of mindfulness and the adherence to mindful organising principles. We offer three solution...

Standardization is believed to be a driver for adoption and integration of digital practices. Beyond the standardization at the level of technology application lies potential for standardization in the higher-order formalized knowledge bases; the so-called ontologies. Ontologies need to abstract and integrate knowledge from disciplines and industry...

Detecting voids in pipe surroundings is essential to structural condition assessment of concrete sewer pipelines. Impact-echo is a non-destructive testing method that can be used for this purpose. This method works based on exciting the surface of concrete and using a contact-based sensor to monitor the propagation of the resulting stress waves. Ho...

Data-driven sewer asset management uses digital sewer representations to store inspection data and to support predictive maintenance planning. This approach requires asset managers to determine what inspection data they need to collect for the assessment of the asset conditions. Existing studies review sewer inspection methods based on their techni...

Purpose This study aims to empirically validate five propositions about the benefits of three-dimensional (3D) visualizations for the management of subsurface utility projects. Specifically, the authors validate whether benefits from 3D in the literature of building construction project management also apply to subsurface utility projects and map t...

Combined utility streetworks involve cable and pipeline owners and authorities that concurrently undertake work in the same physical space. In this networked project setting, ownership fragmentation and lacking formal coordination instruments complicate the integration of multi-stakeholder engineering and construction operations. Boundary spanners...

Ground Penetrating Radar (GPR) is an electromagnetic inspection method that is widely used to help locate and assess conditions of sewer pipes. However, when operated from the ground surface, the method is not efficient in identifying early stages of void formation, which if untreated, can lead to the appearance of sinkholes. To remedy this issue,...

Multimedia in blended learning provides the ability to enhance students’ performance and satisfaction. Microlectures are one type of multimedia that comprise of short modular videos that introduce basic theoretical concepts. Literature provides limited insight into how this specific format supports engineering classrooms. This study, therefore, exp...

The organisational data models that support the information needs of utility network managers are proprietary and domain-specific, while the emerging national standards in this field often lack lifecycle data representation capabilities. However, multiple types of utility networks can be comprehensively represented with the free and open-source Uti...

The collection and depiction of comprehensive and accurate information about subsurface utilities’ locations and attributes—also referred to as utility surveying—has been a priority in the planning, design and monitoring of construction projects for many years. Where internationally comparable utility surveying standards have established (e.g., the...

Three-dimensional (3D) uncertainty representations help to avoid ambiguity in the interpretation of utility data. Existing data models and 3D-solutions do not, however, facilitate this adequately yet. They store uncertainties only by means of textual attributes or require stochastic data and expert input to visualize uncertainties. Such data is dif...

Het IMKL2.1 is de opvolger van het IMKL1.1 en is zowel in topologie als vocabulaire rijker dan haar voorganger. Om gebruikers/ontwikkelaars van het IMKL2.1 er toe te bewegen aan de slag te gaan met het rijkere model zijn een viertal showcases ontwikkeld en beschreven binnen dit rapport om de mogelijkheden van het IMKL2.1 te illustreren. Gepublicee...

The construction industry and its reform agendas commonly assume that digitization of a construction asset's life cycle also integrates its stakeholders. Behind this lies the premise that stakeholders reduce ambiguity and create consistency by using software that operates on the basis of shared and uniform knowledge. To explore this premise, this s...

A persisting stance in practice is that obliteration of rules creates innovation paradise. Although it seems tempting, this view neglects that regulations may also constructively support innovation adoption processes. To stress these different roles that exist between regulation and innovation, scholars call for a careful empirical analysis of inno...

Availability of 3D underground information models is key to designing and managing urban infrastructure construction projects. Buried utilities information is often registered by using different types of location data with different uncertainties. These data variances are, however, not considered in many existing visualization approaches. This stud...

In about six months the project team conducted a literature review and expert consultation round. They identified a range of technologies that can be categorized into two types: global monitoring systems and detection systems, which in turn comprises local push detection systems and local pull detection systems. Monitoring systems essentially detec...

Coordinators of inner city utility construction works face increasing difficulty in managing their projects due to tight physical restrictions, strict deadlines and growing stakeholder fragmentation. This paper therefore presents a 4D CAD based coordination method that supports project plan scoping, formalizing and synchronizing. We developed and i...

This paper reports on an ethnographic-action research study of four-dimensional (4D) based coordination in three utility reconstruction projects. This research shows that implementation of 4D models in planning meetings supports mindful behavior, making stakeholders: (1) sensitive to operational processes, (2) pre-occupied with errors and inaccurac...

This chapter introduces a fieldwork-based method for end-user engaged ontology development. Our approach complements existing methodologies that, despite their aims to consult end-users and domain experts, have not yet formally spelled out steps for end-user engagement in detail. The method we introduce is based on ethnographic-action research. Thi...

Based upon a conceptualization of the engineering design process as pragmatic inquiry, this paper introduces a framework for supporting designers and design managers with a better understanding of the trade-offs required for a successful implementation of simulation tools. This framework contributes to the field of technology implementation researc...

The construction management (CM) domain regularly develops and explores new theories and perspectives. These new insights can shift the existing paradigm radically, they can be assimilated smoothly, or they can stall as they are debated at CM’s domain boundary. During our current research, we experience that the concepts from high reliability organ...

This research explores scheduling purposes and related 4D-CAD requirements during planning and realization of a 900m sewer line construction project. We used an ethnographic-action research approach to investigate how changing scheduling purposes influence 4D-model setup. To this end, we implemented 4D-CAD in a real-life setting, iteratively improv...

This research investigates the role of 4D visualizations in enhancing mindfulness in construction project coordination. We introduce the mindfulness concept—defined as capacity to detect (potential) operational errors and take corrective action—to make a comparison of two distinctive coordination practices. To this end, manual and 4D-supported coor...

To achieve project objectives, construction project managers have to manoeuvre through complex coordination structures. They have to simultaneously deal with limited budgets, tight schedules, demanding stakeholders and a fragmented supply-chain. Despite their extensive coordination efforts, project managers are frequently confronted with unexpected...

Sinds invoering van de nieuwe aanbestedingswet hanteren gemeenten en provincies een ‘EMVI, tenzij-beleid’: in plaats van beoordeling op basis van (louter) laagste prijs, worden werken gegund aan de aanbieder met de ‘economisch meest voordelige inschrijving’. Door deze aanpak kan de opdrachtgever bij het selecteren van een aanbieder ook focussen op...

Construction IT - as ubiquitous computing, location based services, GPS, 3D GIS, 4D design - challenges the work practices in inner city infrastructure projects in terms of improving information exchange between client and contractor and communication with stakeholders in the project environment. Although Construction IT (CIT) can offer benefits to...

To align the majority of the stakeholders during urban planning activities, planning experts organize multi-stakeholder meetings. A main problem during these meetings is that participants do not always have the necessary knowledge to decide or evaluate planning alternatives. Visualization and Simulation (V&S) tools can help to generate this knowled...
