Abstract [en]

Purpose

In the construction industry, it has proven difficult to implement and realize innovation efforts, for example in the development of industrialized construction and use of platform concepts. Thus, the purpose of this study is to characterize the innovation diffusion process in the social system of a large Swedish contractor company. Specifically, the diffusion of three innovative industrialized house-building (IHB) platforms and factors affecting their adoption and implementation (particularly effects of their perceived radicality in relation to the company's decentralized characteristics) are identified and discussed.

Design/methodology/approach

A case study approach was applied, using empirical material including semi-structured interviews and archival records (research reports from earlier studies at different points in time related to each innovation and annual corporate reports). The material was analyzed using Rogers' (2003) five-stage innovation process model, acknowledging the importance of social systems' structures.

Findings

Structural characteristics of the social system strongly affect innovation diffusion. In subsystems that had not been involved in initiation of the innovations, they were regarded as radical, which hindered their adoption and implementation.

Research limitations/implications

This study builds upon the recent findings that successful innovation implementation depends on a range of contingencies in the construction context. Although the diffusion of the innovations per se has been traced over a ten-year period, generalizability is limited because the results come from one construction company.

Practical implications

Contractors have invested substantially in the development of industrialized construction and use of platform concepts, but less in their implementation, so they have obtained little gain. How innovations are perceived and implemented in different subsystems affects the success of their implementation in the overarching social system.Originality/valueThis study adheres to previous calls for more research on firm level in the complex social system of construction companies by adopting a ten-year perspective on the diffusion of innovation at a large contractor addressing in particular the impact of the innovations perceived radicality in relation to the decentralized characteristics of the company.

Abstract [en]

Incorrect prediction of dynamic properties of tall buildings can lead to discomfort for humans. It is therefore important to understand the dynamic characteristics such as natural frequency, mode shape and damping and the influence they have on acceleration levels. The aim of this study is to compare two timber building system, one with cross laminated panels and one with post-and-beam elements with diagonals for stabilisation. Empirical formulae for predicting the natural frequency and mode shape are compared to measured and numerical results. Tall building assumptions such as ‘line-like’ behaviour and lumped mass at certain points were evaluated for both systems. The post-and-beam system showed a stiffer behaviour than the cross laminated system where more shear deformation occurred. Empirical formulae should be used with care until more data is collected.  For the post-and-beam systems an assumption of linearity may be appropriate, but for cross laminated systems the approximation can give results on the unsafe side. Finally, the relationship between stiffness and mass for cross laminated timber systems and its effect on dynamic properties needs to be further investigated.

Abstract [en]

Research Question: How do different flow dimensions and their interrelations appear in Swedish construction settings?

Purpose: To contribute to the ongoing discussion on flow in construction by providing empirical data to a proposed flow model and widening the current understanding within Lean Construction with theory from industrialized construction and operations management.

Research Design: Transcriptions of nine in-depth interviews with managers at different Swedish contractors were utilized to identify different flow dimensions.

Findings: Results show different patterns which describe contractors’ focus on different flow dimensions.

Limitations: The study is performed in Swedish construction companies with limited generalizability to construction in general. Data collection based on interviews might struggle with objectivity and multi-case studies do not coincide with in-depth research in each single case.

Implications: Different flow dimensions are relevant within construction contractors and should be addressed by either management activities or an operations strategy.

Value for practitioners: Increased understanding of flow in construction based on empirical data enables management of different flow dimensions to evolve contractors’ operations strategies towards Lean Construction or industrialized construction.

Abstract [en]

Operations strategies focus on how a firm delivers value, while business strategies focus on what to deliver and where. Lean is an operations strategy prioritizing flow efficiency. In construction, empirical underpinning of operations strategies has been limited. The aim is to capture how perceptions of operations strategy in construction practice aligns with existing theories of operations strategy organized in decision categories. Nine in-depth interviews with contractor middle managers were transcribed and analyzed to capture their perceptions of operations strategies. Results show: (1) decision categories in construction differ from manufacturing, and (2) differences between resource and flow efficient operations strategies exist. A resource efficient strategy focuses cost and delivery as competitive criteria, while customer value is targeted in a flow efficient strategy. Proposed structural decision categories are standardization, organization and production planning, supply chain, and infrastructural decision categories are human resources, continuous improvement, long-term perspective, process vs. project, and performance measurements. Infrastructural categories are more difficult to replicate and render competitive advantage if successfully aligned with business strategy. An operations strategy strictly focused on project delivery, such as lean construction, is not automatically aligned with the business strategy, but can achieve satisfactory project performance.

Abstract [en]

When project teams are pressured to limit internal or external Lean coaching due to budgetary concerns, Lean coaches may not have sufficient time to guide project teams in materials management to support milestones. Consequently, while organized project teams will make the time to develop a strategy for managing key materials that impact the critical path, disorganized project teams will more likely manage most materials on an ad-hoc basis. This lack of a materials management strategy then leads to unrealized profits and hidden wastes on projects. As a result, this research seeks to investigate how to develop a basic materials management framework to help project teams begin determining which bulky materials should be: (1) Using a pull system (e.g., through the use of Kanban cards or milk runs) to coordinate deliveries, (2) Kitted off-site vs. on-site, and (3) Organized into prefabricated assemblies. Specifically, this paper will identify various questions, calculations, and artefacts (e.g., equipment for handling and staging materials, signage used to make the materials management strategy transparent to all project participants) that contribute to establishing a comprehensive materials management strategy. In particular, space management emerges as an important tool to organize the flow of materials to match job-site installation rates.

Abstract [en]

Although the focus remains primarily on high resource efficiency, the significance of flow efficiency in construction is continuously increasing. Flow and resource efficiency describe two competing target viewpoints, which focus on reducing non-value adding activities and maximizing resource utilization, respectively. Recent research has shown that balancing both perspectives provides a viable solution. However, the exact measurement of flow and resource efficiency in construction remains unclear. Therefore, the aim of this work is to evaluate a possible flow and resource efficiency measurement method in the off-site production context of volumetric element construction, and assess the industrial relevance thereof. Work sampling has been used to collect data from a building project flowing through the off-site production system. The validity of the method has been checked statistically, through a focus-group workshop and with calculation figures from the case company. Work sampling allows flow and resource efficiency measurements in an off-site production system. The method delivers current status figures of companies, yielding a balance between flow and resource efficiency.

Abstract [en]

Construction companies traditionally try to optimize their resource efficiency to minimize costs. Today's demand for value stream optimization along the whole supply chain cannot be resolved by that approach. To be able to strengthen the performance of the fragmented construction, supply chain measuring flow efficiency is essential to meet the customer's demand of shorter lead times. A literature study and an exploratory case study on a construction company and its supplier have been done to map existing key performance indicators (KPIs) for measuring both resource and flow efficiency. The outcomes from the literature study show possible KPIs and the connections between them. Results from the case study indicate that basic data for flow efficiency measurements exist in companies but these are underutilized. Balancing resource and flow efficiency is a challenge for all companies. Decisions made on how to manage production and construction affect this balance, thus creating a dynamic situation where the balance is different between building projects.

Abstract [en]

Some of the requirements governing the design of houses are common between projects. This opens up for using modularization based on product commonalities. Though modularization is well known in the manufacturing industry, its use in house-building contexts is less studied. Even more scarce is research focusing on how requirement commonalities between one-of-a-kind products are found and managed in a modularization process. In this research, modularization from a requirements management perspective is empirically explored using a case study approach. Though the studied modularization process can be described as sequential, the process steps are highly interrelated, with overlaps and iterations. Commonalities are found by functional decomposition of the customer's portfolio projects, tracing technical solutions back to their initial requirements. These are balanced with the customer's requirements on the product and on the design automation tool. The requirement list is continuously updated based on portfolio analysis and communication of modularization results to the customer

Abstract [en]

Several methods exist for design management such as Agile project management, the Last Planner System®, and configuration in diverse variants. Construction can be realized using different degrees of pre-engineering i.e. different production strategies, which can affect the design management method. The research aim is to describe different design management methods and discuss their capacity to function in existing production strategies in construction. Data was collected as secondary data from earlier publications on Agile project management, the Last Planner® system, configuration, and visual planning. Agile project management has a strong focus on customer value and lends itself well to situations with little pre-engineering. The Last Planner System® in design has a strong focus on the co-creation of flow and coordination of actions. In industrialised housing a dialect of Last Planner System® named KI-VP is implemented drawing upon predefinition of design tasks through standardized work. Configuration is the ultimate predefined design stage, where everything can be automated based on product variants.
