Evaluating the procurement documents of Dutch water boards portfolio: A step towards more reliable public clients
No full textAlthough a considerable amount of literature has addressed the public procurement in the construction industry, still little is known about procurement in small and repetitive activities. In practice, however, public clients are often involved in repetitive tasks such as maintenance activities. Dutch water boards, regional governmental bodies responsible for providing water management services, are the focus of this study. For this research, three main procurement documents of the water boards were performed using content analysis. The aim is to evaluate these documents and to identify the typology of the repetitive activities and the procurement volume of these tasks from a portfolio perspective of the public client. Most of the contractors/suppliers involved in these activities are local Small and Medium-Sized Enterprises (SMEs). The findings of the study indicate that insights into the typologies of these repetitive works and their expected volume over time delivers crucial value for the public procurer. Given the amount of repetitive works procured by public clients, creating such an insight to both clients as well as contractors can ultimately increase efficiency and improve investment opportunities.Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Design & Construction Managemen
The impact of shifting values on the role and responsibilities of the construction client in delivering public goods
No full textIn today’s construction industry we witness an increase in public private collaboration in the delivery of public goods. By transferring operational responsibility to private contractors, public construction clients have fewer possibilities to directly influence and steer the outcomes of these processes while remaining socio-political responsible.In this paper we aim to explore how public construction clients try to find a balance in public value management activities by rethinking their roles and responsibilities in the client-contractor relationship. This paper results of a set of semi-structured interviews with different actors playing a part in commissioning of organisations with different degrees of publicness are presented. Results indicate that the alignment of the client role and change in responsibilities should be rather flexible in order to deal with the restrictions that procedural values such as lawfulness, reliability and transparency bring along. This requires significant changes in the interpretation of the commissioning profession and the transformation of the collaborative relationship in public private collaboration. Further research should look more closely into the alignment of the shifted roles and responsibilities and organizational- and steering mechanisms that could be applied to enhance this value shift in practice.Public Commissionin
The public construction client of the future: Network-based collaborator in a traditional public administrative system
No full textIn the construction industry, public and semi-public clients increasingly depend on private parties to achieve project outcomes by adopting network type of governance approaches. However, social-political responsibilities remain at the public side. Hence, the general challenge for public commissioners is to find a new balance between dependency and responsibility when safeguarding competing traditional and network values. Based on three qualitative studies of a PhD project on safeguarding public values by public construction clients, applying concepts from public administration and public value theory, this paper presents three lessons learnt on future roles and responsibilities. We argue that future 'good' commissioning should be 1) more about embedding new value systems and less about changing existing values mechanisms, 2) more about paradox thinking in a convener role and less about trade-offs in a steering role and, 3) more about informal accountability in the value chain and less about formal accountability in the project chain. To ensure the 'right' kind of interference in the value process, public clients' way of coping with publicprivate conflicts, needs to correspond with the internal governance arrangements, and vice versa. Further research should focus on facilitating this alignment by providing a public value safeguarding strategy tool for public construction clients.Public Commissionin
From Agents to Stewards? Experiences from a Dutch Infrastructure Case Study
No full textIn the construction industry clients largely depend on contractors to deliver projects. According to agency theory problems of goal conflict and information asymmetry arise in this delegation of work because both the principal and the agent are self- interested. The control-oriented governance mechanisms that agency theorists propose as a means to resolve these problems can act counterproductive and give rise to new problems. Stewardship theory offers a counterweight to agency theory and assumes a relational reciprocity between the principal and the steward. Recently, a large group of Dutch public construction clients and contractors have collaboratively expressed their desire to improve their relationship in a manifest called ‘the market vision’. This phenomenon can be interpreted as a desire to shift from a principal- agent towards a principal-steward relationship. The aim of this paper is to explore how public clients engage in stewardship relationships with contractors. This research is based on a case study of one of the most ambitious projects under the umbrella of this market vision trajectory. The analysis of the documents, observation notes and semi-structured interviews with project team members indicate that they developed a relationship which can be characterised as a principal-steward bond. By investing in relationship-building from the pre-commercial phase, throughout the tender phase and the execution phase, they put their individual differences beside in order to reach their initially defined common goal. It remains however to be seen whether this can be considered as a complete stewardship relation.Public Commissionin
Implementation of circularity in the building process: A case study research into organizing the actor network and decision-making process
No full textCircularity aims to reduce waste by closing and narrowing resource loops and by extending the lifetime of materials and products. As a consequence of this fundamentally different approach to construction practices, implementation entails a different organization of the building process. The purpose of this research is to make recommendations with respect to the actor network and the decision-making process to facilitate implementation of circularity in construction practices. First, a theoretical framework is developed to structure and prioritize decision-making to implement circularity based on resource and value strategies. Second, this framework is applied to three circular building cases in the Netherlands, relying on stakeholder interviews and documentation. These cases include a renovation project, a newly built project, and a transformation project. Third, analysis of the case study data demonstrates the actor network and decision-making process including the following aspects: Actors, resources, relations, positions, influence, and decision rounds. It can be concluded that: i) some conventional actors have acquired knowledge on circularity; and ii) expert actors emerged who have specialized in circularity. Both types of actors are a prerequisite iii) to implement circular strategies for the beginning and end phase of the building's lifetime; and iv) should be involved early on (in the design-making processes) to influence decision-making on circularity, especially concerning the long-lived layers of a building.Design & Construction Managemen
A case based comparison of the efficiency and innovation potential of integrative and collaborative procurement strategies
No full textThe purpose of this paper is to investigate and compare in what ways different types of integrative and collaborative procurement strategies may enhance efficiency and innovation in public infrastructure projects. Further, implementation challenges are identified and discussed. Interview-based case studies were performed of ten infrastructure projects in Sweden and the Netherlands. The projects involve four types of collaborative procurement strategies - collaborative Design-Build (DB) contracts, Early Contractor Involvement (ECI) agreements, Design-Build-Maintain (DBM) contracts and Design-Build-Finance-Maintain (DBFM) contracts. The findings indicate that the duration of the collaboration is fundamental in setting the limits for innovation and that early involvement as well as long-term commitments open up for more innovation. Naturally, the potential for increased efficiency is higher than for innovation and also occurs in collaborations with limited duration. These integrated project approaches, however, still appear to be in an early stage of learning. For a public repeat client to realise the full potential of a new strategy, it is important to have a long-term perspective and capabilities to analyse and learn from the experiences.Public Commissionin

Construction in the platform society: New directions for construction management research
No full textAn emerging aspect of digital transformation in industry relates to the rise of digital platforms. While examples such as Uber and Airbnb are well-known, technological platforms that seek to coordinate demand and supply-side actors in the architecture, engineering and construction (AEC) sector are also developing. Examples include Wikihouse, Sidewalk Labs, and Bosch IoT Suite. Although there is a growing body of scholarship reviewing the concept of 'platforms', far less attention has been paid to reviewing studies of digital platforms in the AEC sector. This systematic review of 18 studies seeks to address this deficiency. The findings show that the focus has hitherto centred on engineering platforms, with researchers adding greater functionality to platforms in order to yield efficiencies in the production process. Current endeavours tend to be laboratory-based, with prototypes still to be tested in the real-world. In contrast to reviews in management and organisational studies, scholars of platforms in construction do not pay as much attention to the power of platforms as a strategic organising principle for coordinating markets. The review thus proposes a number of possible directions for construction management researchers to examine the strategic potential for platforms to drive competitive advantage in the AEC sector.Design & Construction Managemen
Teacher Compensation and Structural Inequality: Evidence from Centralized Teach
Full text linkThis paper studies how increasing teacher compensation at hard-to-staff schools can reduce inequality in access to qualified teachers. Leveraging an unconditional change in the teacher compensation structure in Peru, we first show causal evidence that increasing salaries at less desirable locations attracts better quality applicants and improves student test scores. We then estimate a model of teacher preferences over local amenities, school characteristics, and wages using geocoded job postings and rich application data from the nationwide centralized teacher assignment system. Our estimated model suggests that the current policy is both ineficient and not large enough to effectively undo the inequality of initial conditions that hard-to-staff schools and their communities face. Counterfactual analyses that incorporate equilibrium sorting effects characterize alternative wage schedules and quantify the cost of reducing structural inequality in the allocation of teacher talent across schools
