This study reports on a survey on project managers' priorities. The survey used ISO 21500 as a scaffold to ask various respondents, like junior, experienced, and senior project managers, project sponsors, and students, to share their perceptions on the priorities for junior project managers. The respondent groups shared similar perceptions....

Comprehensive understanding of the merits of bottom-up urban development is lacking, thus hampering and complicating associated collaborative processes. Therefore, and given the assumed relevancies, we mapped the social, environmental and economic values generated by bottom-up developments in two Dutch urban areas, using theory-based evaluation...

The emergence of organic planning practices in the Netherlands introduces new, non-conventional, local actors initiating bottom-up urban developments. Dissatisfied with conventional practices and using opportunities during the 2008 financial crisis, these actors aim to create social value, thus challenging prevailing institutions. Intrigued...

Despite the efforts of governments and firms, the construction industry is trailing other industries in labour productivity. Construction companies are interested in increasing their labour productivity, particularly when demand grows and construction firms cope with labour shortages. Off-site construction has proved to be a favourable policy...

Refurbishment projects notably for social housing are special kinds of project for many reasons, including inflexible existing stock, low available budgets, involvement of residents staying in their homes during construction. Lean tools could be helpful not only during construction, but also in the preparation of projects including requirements...

Productivity in construction is relatively low compared to other industries. This is<br/>particularly true for labour productivity. Problems that contribute to low labour<br/>productivity are often related to unorganised workspace, and inefficient organisation of work, materials and equipment. In terms of time use, site workers spend time on...

De afgelopen jaren is onderzoek gedaan naar nieuwe concepten voor bouwlogistiek en bij negen proeftuinen in binnenstedelijk gebied is aangetoond dat hier forse winst is te behalen in termen van besparingen op logistieke kosten en bouwtijd, betere doorstroming, minder schadelijke uitstoot en minder hinder voor de omgeving. Zo bleek het mogelijk...

The construction and renovation of the building envelope represents a significant fraction of a project’s life-cycle costs. It also has a determinant effect on the potential reduction in energy use, as well as on the improvement of the building’s indoor comfort. Nevertheless, the challenge of a low rate and depth in building energy renovations...

his study investigates whether integrative and collaborative practices of the construction industry can be exclusively attributed to integrated project-delivery methods or whether traditional project-delivery methods also foster integration within project-based design teams. Project managers assessed team collaboration and the integration of...

The way in which construction logistics is organised has considerable impact on production flow, transportation efficiency, greenhouse gas emissions and congestion, particularly in urban areas such as city centres. In cities such as London and Amsterdam municipalities have issued new legislation and stricter conditions for vehicles to be able to...

This paper presents a research endeavouring to model site work in a 4D BIM model. Next simulations are performed with this model in 5 scenarios including specific interventions in work organisation, notably changing positons of facilities for site workers. A case study has been done in a construction project in the Netherlands. The research has...

The vast amount of previous research on project management competence does not provide a basis for educational needs. Analyzing previous research poses two challenges: the lack of a uniform list of competences, necessitating a taxonomy, and the use of importance as a criterion, favoring general important competences. Criticality is introduced as...

Building Information Modelling (BIM) technology and the concept of supply chain management (SCM) could be a potentially compatible and mutually interdependent practice. The existing research on BIM focuses on improving project-based and intra-organisational goals, ignoring the impact of BIM on existing structured long-term Supply Chain (SC)...

Last few years the hindrance, accidents, pollution and other negative side effects of construction projects and namely construction transport have become an issue particularly in urban areas across Europe such as in London, and in the Netherlands as well, including the cities of Utrecht, Rotterdam and Amsterdam. Municipalities have issued new...

According to Eriksson (2015) ‘there is still a lack of comprehensive conceptual and practical frameworks that enable both a detailed and systemic understanding of integration in project-based supply chains.’ He therefore developed a theoretical framework that includes the four dimensions of strength, scope, duration and depth of integration. In...

This paper explored the status of BIM adoption in construction Supply Chains (SC). The benefits of BIM are found from design management, to virtual construction and site management. The study is structured upon the assumption that BIM not only supports intra-firm collaboration, but also improves inter-firm collaboration in projects with SC...

This paper proposes a model to integrate the construction Supply Chain (SC) through Building Information Modelling (BIM). The various information flows in the construction SC are vague. BIM is an aspiring integrator of information that could potentially improve such multi-disciplinary information flows. The paper presents a method to bridge...

The purpose of this paper is to explore and categorise the different approaches used to determine organizational effectiveness of construction project organizations. First, the conceptualization of organizational effectiveness is reviewed. This resulted in three main approaches that are used to categorise the approaches used within construction...

In the Dutch building sector, and in the social housing sector in particular, supply chain collaboration between housing associations and their supply chain have been quite popular since last five years or so. Many associations and their supply chain partners have tested, and in many cases continued to apply various representations of supply...
