Som forskare bakom Störningsfri stad-projekten är vi glada att få dela med oss av våra insikter och resultat i denna samling texter. I takt med att våra städer växer och förändras uppstår utmaningar kring tillgänglighet, transport och hållbarhet – frågor som ofta hamnar i skuggan av de stora byggprojekten. Med denna antologi vill vi belysa just dessa utmaningar och lyfta fram lösningar som kan bidra till en mer välfungerande och hållbar stadsutveckling, även under byggtid. Vi hoppas att denna bok ska inspirera, ge nya perspektiv och vara till nytta för dig som är intresserad av framtidens stadsplanering.

In complex projects, such as hospital constructions, there are large interdependencies betweenthe actors involved, especially relating to the flow of materials and resources. As new hospitalbuildings are often built on existing blocks and campuses, ongoing hospital operations may hinderlogistics and construction operations and vice versa. To handle these issues, it has becomeincreasingly common to implement construction logistics setups (CLSs). The purpose of thepaper is to analyse how the centrality of the CLS in the project organization affects the coordinationand conflict level in complex construction project management using a power dependencylens. The study is based on case studies of six hospital projects in the Nordic countries.Based on a cross-case analysis it is identified that: 1) from a logistics management perspectivewe identify three different foci of the CLS; i) security for hospital patients and staff, ii) on-sitematerial flow coordination, and iii) flow coordination to and from site, and 2) from a projectmanagement perspective the main findings point towards the importance of centrality of theCLS in the project management organisation in order to ensure enough power to mandateenforcement of coordination.

Purpose The purpose of this study is to identify how the responsibilities and costs of planning, controlling and executing the material, resource and waste flows are shifted between actors when introducing a construction logistics setup (CLS) as a product innovation in a construction project, compared to the traditional way of organizing these activities.

Design/methodology/approach This study is an analytical conceptual research study which aims to bring new insights into a problem through logical relationship building. Empirical data are gathered in two cases where CLSs are used, through observations and interviews regarding how the activities within the order-to-delivery process are performed. The results have been discussed at workshops with suppliers, installation companies, contractor firms and trade unions.

Findings The outcome of this study is a model for illustrating how costs and responsibilities are shifted in the construction project and supply chain when a CLS is introduced. The cost shift is dependent on the activity shift that accompanies the services included in the setup.

Practical implications The practical contribution of this work is twofold. First, this study provides a methodology of how to evaluate the impact of logistics services on the actors in the construction project. Second, this study shows shifts in costs and responsibilities in logistics activities with the introduction of construction logistics services.

Originality/value The theoretical contributions of the model and this study lie in the inclusion of a multi-actor perspective in total cost modelling in supply chains.

Construction logistics services can, if implemented with high quality, positively impact both efficiency and sustainability of construction projects. However, present quality management frameworks have not been developed for temporary multi-actor contexts, such as construction, which is largely lacking industrialised processes. Still, construction logistics service providers provide service offerings to temporary settings and could thus benefit from a service quality perspective. Applying this perspective, this study supports the quality improvement of construction logistics services by using a service modularity approach to identify the services to prioritise for improvement. Building on interviews, concept mapping, and a service blueprint of a construction logistics setup, a priority matrix for improvements is developed. The first step in using this matrix is to operationalise the construction logistics setup in modules based on blueprinting. Second, the matrix evaluates the modules against nine empirically derived improvement enablers such as practices and forums for learning, and data measurements enabling the comparison and followup of construction logistics services. In conclusion, the priority matrix helps focus the improvements on modules with high likelihood of successful improvements. Improvements that can become sustained over time through the reuse of standardised modules in upcoming projects.

Sweden is at EU bottom of circular soil and rock masses. The purpose of this study is to capture the relationship between the overall system and subsystems of circular soil and rock masses to identify barriers to establishing efficient circular soil and rock material flows. The main hinders are lateness of action, legislation, and lack of information sharing. This together creates a relational mess between the subsystems, leading to a lack of understanding of how to act. The relations must be clarified before public procurement will have its intended impact to increase circularity and decrease transport emissions.

The purpose of the paper is to capture non-value adding activities of the order-to-delivery process at the interface between construction site and the supply chain to identify efficiency improvement potentials. The paper is based on a case study of a Swedish construction site. The unit of observation has been the activities taking place at the interface between construction supply chain and construction site. i.e. deliveries and on-site material handling. Data is collected through observations in the unloading zone of the construction site, unstructured interviews, and a workshop with site management. The findings of the paper show that there exists fuzziness in the interface of construction supply chain and construction site causing the observed non-value adding activities such as waiting, excessive material handling, unnecessary vehicle movements etc. The root causes of the fuzziness are poor planning, lack of communication between site management and transporter/material supplier, and lack of standard operating procedures for unloading. The paper provides knowledge of the importance of managing interface between construction supply chain and site to remove non-value adding activities. Additionally, the paper provides a clear view of the different actors’ roles in the non-value adding activities and give suggestions of how to improve efficiency of construction deliveries. The paper is based on a single case study and further studies are needed to provide deeper insights into the phenomenon.

Purpose – The noise and dust particles caused by the construction transport are by most stakeholders experienced as disturbing. The purpose of this study is to explore how sonification can support visualization in construction planning to decrease construction transport disturbances.

Design/methodology/approach – This paper presents an interdisciplinary research project, combining research on construction logistics, internet of things and sonification. First, a data recording device, including sound, particle, temperature and humidity sensors, was implemented and deployed in a development project. Second, the collected data were used in a sonification design, which was, third, evaluated with potential users.

Findings – The results showed that the low-cost sensors used could capture “good enough” data, and that the use of sonification for representing these data is interesting and a possible useful tool in urban and construction transport planning.

Research limitations/implications – There is a need to further evolve the sonification design and better communicate the aim of the sounds used to potential users. Further testing is also needed.

Practical implications – This study introduces new ideas of how to support visualization with sonification planning the construction work and its impact on the vicinity of the site. Currently, urban planning and construction planning focus on visualizing the final result, with little focus on how to handle disturbances during the construction process.

Originality/value – Showing the potentials of using low-cost sensor data in sonification, and using sonification together with visualization, is the result of a novel interdisciplinary research area combination.

The purpose of this paper is to provide insights into how supply chain management canbe taught using megagames as a pedagogical motor. This study has had a longitudinalaction research approach to student centred learning as it builds on a previous paper onintroducing a theme of cross-functional decision-making through combining lectures,case assignment, and computer-based tools. Combining case work and the megagame hasled to activity independence and room for new reflections. What can be seen is thatexchanging the computer-based tool for a megagame has allowed students a deeperunderstanding of not only decision-making, but also decision-formulation.

While being a significant part of the urban development, construction projects disturb different stakeholders in various ways. There are three problems associated with construction disturbances: (i) most of these disturbances are not recognised by the people causing them, (ii) they are not monitored and (iii) if they are to be monitored, data is spread among stakeholders. This paper defines what a disturbance is, presents a list of disturbances, linking disturbances to stakeholders and, categorising them based on their distance from construction sites (responding to (i)). Next, a IoT domain model is developed, demonstrating how IoT in construction needs to be combined with the sensors of smart cities to capture the primitives of these disturbances (responding to (iii)). This is a first step towards enabling large-scale data-gathering of construction transport disturbances (responding to (ii)), which is a necessity to predict them and allow better construction transport planning to decrease disturbances.

Construction transport have a severe environmental impact. To address the environmental problems requires that the complexity of construction, including the many different actors and their goals, is captured. The purpose of this article is to propose a new conceptual model for construction logistics systems, with the aim of advancing the transition to more environmentally friendly construction transport. The conceptual model was developed based on different theoretical frameworks, and also improved based on practitioner's workshops. The conceptual model is based on five interconnected layers of activities: urban land use; construction; construction supply chain; transport; and infrastructure and three subsystems. The model indicates on what layers different actors in the subsystems act and how different actors can influence the environmental performance of construction logistics systems by their decisions. In relation to similar multi-layer models, construction logistics also need to embrace municipal actors. For example, the traffic planning may offer available infrastructure to improve fill rates and energy efficiency, but fill rate is the direct result of the suppliers decisions, which is indirectly affected by the main contractor's schedule. In particular, modal split is influenced by a range of decisions by different actors, complicating the selection of a more environmentally friendly transport mode.
