Purpose The design phase is generally characterized with two-way multiple information exchanges/overlaps between the interdependent entities. In this paper, entity is a generic term to represent teams, components, activities or parameters. Existing approaches can either capture a single overlap or lack practical application in representing multiple overlaps. The beeline diagraming method (BDM) network is efficient in representing multiple overlaps for construction projects. However, it considers any entity as indivisible and cannot distinguish partial criticality of entities. In reality, the design phase in any construction project is driven by need basis and often has numerous interruptions. Hence, there is a need to develop an alternate network analysis for BDM for interruptible execution. The paper aims to discuss these issues. Design/methodology/approach A pilot study is conducted to formulate the hypothetical examples. Subsequently, these hypothetical BDM examples are analyzed to trace a pattern for criticality. This pattern study along with the existing precedence diagramming method network analysis enabled to derive new equations for forward pass, backward pass and float. Finally, the proposed concepts are applied to two design cases and reviewed with the design experts. Findings The proposed network analysis for BDM is efficient for interruptible entity execution. Practical implications The proposed BDM network is an information-intensive network that enables the design participants to view the project holistically. Application to two distinct cases emphasizes that the concept is generic and can be applied to any project that is characterized with beelines. Originality/value An alternate network analysis for BDM is investigated for interruptible entity execution. This study also clarifies the related concepts – interdependency, iteration, overlaps and multiple information exchanges/linkages.

Purpose The ability of construction contractors to engage in construction bond agreement with guarantors depends on capital, experience, capacity and continuity. Using these criteria, the purpose of this paper is to provide insights into the bonding capacity of Nigerian contractors. Design/methodology/approach Factors required for bonding were examined based on a set of questions addressed to managers of contracting firms and personnel involved in issuing bonds and guarantees in commercial banks and insurance companies. The scorecard approach was employed to determine the bonding capability of the contractors. Findings Contractors’ financial strength and past performance on previous projects are the two important factors considered by guarantors in granting bond to contractors. However, the condition surrounding the bond, the legal capacity of the guarantor to issue bond and the identity of the guarantor are mostly considered by contractors in approaching a potential guarantor. Using the scorecard approach, about one-third of contractors have the necessary requirements to engage in construction bond agreement with guarantors. This ability of contractors is affected by years of experience of the firm but not by their location nor years of experience of their manager. Practical implications It is necessary for contracting firms to increase their capital base through merging, borrowing, etc., and also engage experienced professionals and workers in the execution of construction projects, as this will eventually improve their bonding ability. Social implications The study is limited to construction contractors registered with Ondo and Lagos State Governments and guarantors that are banks and insurance companies in Nigeria. Originality/value The paper specified various areas of concerns for Nigerian contracting firms in their bid to enhance their bonding ability. This will help them in overcoming various challenges and bottlenecks that may arise in securing bonds and guarantees from guarantors.

PurposeCollaboration is essential to BIM-enabled construction projects (BECPs). To facilitate collaboration, various strategies have been proposed. Usually, project team adopts single collaboration strategy for convenience. However, BIM-based collaboration is rather dynamic and exposed to a lot of barriers and risks, which easily changes collaboration conditions among partners. Therefore, better understanding of collaboration conditions in BECPs is crucial to develop flexible and suitable strategies. To fill in the gap, this study intends to identify typical collaboration profiles in BECPs and develop a profile-oriented strategy selection framework.Design/methodology/approachThis study establishes a six-dimensional collaborative behavior matric based on a comprehensive literature review to profile collaboration. Then a questionnaire survey is conducted to collect the collaboration data from 162 BECPs in China. Finally, latent profile analysis (LPA) is utilized to identify the typical collaboration profiles in BECPs.FindingsThrough LPA, four profiles are identified, including restricted collaboration profile, smarmy collaboration profile, intuitive collaboration profile, and modest collaboration profile. A profile-oriented strategy selection framework is also established to match strategies with collaboration profiles. Two major categories of strategies are proposed to promote these collaboration profiles including trust building and elevating strategies and collaborative behaviors facilitating strategies.Research limitations/implicationsThese identified profiles can provide an insightful understanding on the diversified collaboration conditions in BECPs.Practical implicationsThe profile-oriented strategy selection framework will help managers develop strategies flexibly to promote collaboration in BECPs.Originality/valueThis study validates four typical collaboration profiles in BECPs. Moreover, a profile-oriented strategy selection framework is also established for collaboration facilitation in BECPs.

PurposeThe purpose of the paper is to develop a method to integrate the schedule-based analysis with a productivity-based analysis to prove and support the result of the damages calculation.Design/methodology/approachIn this paper, a “cost and schedule impact integration” (CSI2) model is proposed to objectively show and estimate lost productivity due to changes in construction projects.FindingsA schedule-based analysis to include separate tracking of change order costs can be used to predict productivity due to the delay and disruption; changes in construction projects almost always result in delay and disruption. However, the schedule-based analysis needs to be integrated with a productivity-based analysis to prove and support the result of the damages calculation.Practical implicationsThe results of this study expand upon construction practices for proving and quantifying lost productivity due to changes in construction projects.Originality/valueThe contribution of the paper is summarized as the introduction of a “schedule impact analysis” into a “cost impact analysis” technique to assess the damages, as well as to demonstrate the labor productivity impact due to delay and disruption in construction projects.

Purpose – The purpose of this paper is to explore the rise of strata manager as a newly emergent profession and note their impact on the governance within medium and high density, strata titled housing such as flats, apartments, town-houses and CIDs. Design/methodology/approach – This research presents finding from a small scale, qualitative research project focused on the interaction between the owner committee of management and strata managers. Findings – The introduction mandatory certification is championed by industry bodies. The strata managers considered they already demonstrated valuable attributes desired by committees of management. These differed to the attributes targeted by the new training regime, and the attributes valued by the committees of management. Research limitations/implications – This is a small scale pilot study. A larger study will need to be undertaken to confirm these results. Practical implications – There is a disjunct between the training and what strata managers consider relevant to undertaking their duties. This has significance for the ongoing governance of these properties and industry professionalisation. The resilience of Australia’s densification policies will depend on how learning will translate into better governance outcomes for owners. Social implications – One in three people within Australia’s eastern states lives or owns property within strata titled complex (apartments, flats and townhouse developments). The increasing number of strata managers and professionalisation within their industry has the ability to impact an increasing number of people. Originality/value – The impact of this new profession, and their requirements in terms of expertise has not been fully considered within existing academic literature.

Purpose Destination marketing organizations (DMOs) use Twitter to promote attractions and special events and to build brand awareness. Tweets of a DMO spread through a complex network of connected accounts. Some of these are more influential than others due to their position within the network. This paper aims to use a network analysis of 14 DMOs to identify the categories of influencers that have the greatest reach. Design/methodology/approach NodeXL was used to download and analyze network data from Twitter during July 2016 for a collection of DMOs promoting US cities. Accounts in the networks were ranked using several measures of relative influence such as the number of times the accounts mentioned/retweeted others or were mentioned in posts about the DMO. The most influential accounts in the network were identified and coded by category. Findings Media, promotional accounts and those of individuals were determined to be influential by each metric considered. Stakeholders such as hotels and restaurants occupy positions of low importance in the networks and generally do not capitalize on opportunities provided by the DMOs. Practical implications DMOs can seek out strategic partnerships with key influencers to maximize their effectiveness. Additionally, stakeholders can improve their Twitter presence by interacting with the DMOs and other influential accounts. Originality/value This paper identifies influencers that can aid in DMOs’ marketing campaigns. It also presents a methodology that can monitor the effectiveness of such campaigns, something absent in the current literature.

Purpose The purpose of this paper is threefold: the primary purpose is to suggest a real estate paradigm spectrum to act as reference for the contextualisation of observed market phenomenon in system terms; the secondary purpose is for the spectrum to contextualise the efficacy of real estate and valuation theory, methods and techniques; and the tertiary purpose is to propose a confidence score for reporting uncertainty to the end user of a valuation report. Design/methodology/approach Literature was reviewed on the concepts of risk and uncertainty, rationality and several systems thinking domains. Findings The framework can provide context to observed market phenomenon and distinguishes between agency and mechanism in contributing to conditions of certainty and uncertainty. The argument followed in this paper is that it is necessary to contextualise the efficacy of real estate and valuation theory, methods and models under conditions of certainty, normal uncertainty and abnormal uncertainty. The characteristics of conditions can be used as basis to develop new theory and practical application or modify existing. Practical implications Real estate economic theory can be organised in terms of the spectrum and the framework can potentially identify where further research is required and the requirements it must meet as measured against the characteristics of the framework. Current valuation methods and models can continue to be used when valuing under conditions of certainty, however, modifications to methods and models are required to account for complexity when valuing under conditions of normal uncertainty and abnormal uncertainty. The confidence score included in this paper can also be used to report the conditions of certainty/uncertainty under which the valuation was performed. Originality/value This paper aims to set the basis for new theoretical and practical developments of insights into real estate economic and valuation theory, methods and models while also contributing to the reporting of uncertainty through the proposed confidence score.

Purpose The purpose of this paper is to describe whether and how groups of nursing home residents respond to the interactive device “the CRDL”. The CRDL can translate touches between people into sounds. It recognises the type of touch and adjusts the produced sound accordingly. Design/methodology/approach This was as an observational explorative study. Responses were coded and analysed using an existing theoretical framework. Findings The CRDL creates an atmosphere of playfulness and curiosity. It lowers the threshold to touch, provides an incentive to touch and encourages experimentation with different types of touches on arms and hands. The sounds the CRDL produces sometimes trigger memories and provide themes to start and support conversation. Involving a (large) group of nursing home residents to interact with the CRDL is challenging. Research limitations/implications In order to more fully understand the potential of the CRDL, its use should be studied in different group and individual sessions and the effects of tailored content, adjusted to individual preferences and/or stages of cognition should be explored. Finally, the effects of using the CRDL on the general wellbeing of nursing home residents should be studied. Practical implications The CRDL can help caregivers to use touch to make contact with (groups of their) residents. A session should be guided by an experienced caregiver. Some familiarisation and practice with the CRDL are recommended and a quiet environment is advised. Originality/value This paper demonstrates the potential of interactive objects, such as the CRDL, in the nursing home.

PurposeThe purpose of this paper is to synthesize taxonomical criteria that can be used for assessing research constructs and assess current business model conceptualizations. The paper attempts to show how the criticism plaguing current business model conceptualizations could be removed with future conceptual development against these taxonomical criteria.Design/methodology/approachThe paper synthesizes taxonomical criteria and assesses current business model conceptualizations.FindingsThe results of the paper revealed that the current business model concepts comply poorly with the taxonomical criteria. The assessment of taxonomical compliance in this paper exposed major opportunities for enhancements in the existing conceptualizations of business model.Research limitations/implicationsThe findings of the paper outline novel avenues for future research in developing more coherent and rigorous business model conceptualizations.Practical implicationsThe practical implications of the paper are that current conceptualizations of a business model are at best incommensurate and at worst even misleading. This paper presents criteria that may be used in guiding the necessary caution and careful deliberation when practical application of the current business model conceptualizations is enforced.Originality/valueThe paper is original in that it establishes the taxonomical criteria, which may be used in research seeking to develop more sound and rigorous business model conceptualizations. To advance this new field the paper concludes that the taxonomical criteria can aid in the future research endeavors to design relevant business model conceptualizations.

Purpose The purpose of this paper is to report on studies on the ethics in the design phase in Norwegian construction projects. The ambition is to establish a descriptive picture of ethical challenges practitioners meet in the design phase in order to raise awareness among them. Design/methodology/approach In addition to a literature review and a document study of ethical frameworks within the industry, interviews with key participants were carried out according to a qualitative approach. The study was undertaken in order to address framework conditions for handling ethically challenging situations, challenges of an ethical nature practitioners commonly encounter in the design phase and finally the structural (systemic) reasons for such challenges. Findings This research finds indications of actors manoeuvring in the design phase for own benefit at the expense of other actors. The findings equally indicate that the design phase poses significant challenges in light of tender documents pricing and exploiting cost reimbursement contracts. In some of the projects examined, participants shifted loyalty after novation contracting and they actively tried to steer the decision processes in their own favour. Originality/value There does in fact seem to be perceptions of a room of manoeuvre between what is unlawful and what is ethically sound in this phase.

Purpose The purpose of this study is to investigate the perceptions of property investors of the risks and returns associated with property crowdfunding as an investment vehicle. The study contributes to the understanding of alternative property investment vehicles and how it is perceived by investors. Design/methodology/approach The study focusses on investor perceptions in using property crowdfunding as an investment vehicle and follows a survey-based design. A questionnaire was finalised after the completion of a pilot study and was distributed to existing property crowdfunding investors via email. Inferential statistical measures were used. Findings The results show, to an extent, similarities to general equity-based crowdfunding studies. However, the uniqueness of property crowdfunding as an investment vehicle may explain the insignificance of the results when related to other studies. Overall, the property crowdfunding investor seems to present cautious behaviour with a conservative perception of property crowdfunding as an investment vehicle. Practical implications It is recommended that property crowdfunding platforms present prospective investors with more formal regulation of the property crowdfunding industry. Such a regulatory framework may lessen the current level of uncertainty presented by investors. Originality/value The study enhances the understanding of the role of property crowdfunding as an alternative investment vehicle in Australia. More importantly, it went some way towards enhancing the understanding of how investors perceive and behave vis-à-vis property crowdfunding as an investment vehicle.
