An investigation into whether building information modelling (BIM) can assist with construction delay claims

It is probable that a construction project anywhere in the world will encounter some form of delay as a consequence of change. The impact of the delay on the project will vary but it is likely to have a negative financial outcome. Compensation can be requested by an affected party in the form of a claim; however, issues of liability and quantum can be difficult given the ever increasing complexity of construction work involving numerous differing successive parallel tasks with varying levels of interrelated resources. Experts are often employed to analyse delays based on project records and report their findings to a tribunal. This paper identifies the difficulties associated with the retrieval and representation of information for delay claims and recognises technological opportunities to deal with these challenges. The potential to exploit aspects of BIM to support these possibilities are discussed concluding that it can assist through the ease of access to coordinated contemporaneous project information and the use of visualisation through multiple dimensions. In order to support this initiative a detailed review of the literature is undertaken which forms part of an Engineering Doctorate

Supporting future-proof healthcare design by narrowing the design space of solutions using building information modelling

BIM has been characterized by the UK Government’s chief construction adviser as unstoppable regarding its rise in construction and he further positioned BIM as mandatory for public projects in the UK by 2016. Moreover, large scale public projects such as healthcare facilities must be seen as a process, being able to meet the constantly changing demands imposed on healthcare infrastructure. Facilities should be designed as change-ready rather than to meet fixed requirements, therefore, the designer should accommodate as large section of design space potential solutions instead of mistakenly narrowing the response of the project to only one solution. Scenario based design was employed as research and design method for the proposed software modules which would extend the Activity Database (ADB). Two modules are proposed that will enable designers to improve their spatial design decisions for both new and refurbishment projects through partially automated knowledge extraction. Additionally, the integration of flexibility and standardisation concepts has been addressed. The proposed design approach is intended to provide rich knowledge representation at the early stages of the design process in less time and effort

Using Building Information Modelling (BIM) to design flexible spaces with design standards in healthcare facilities

This paper explored key factors that can enhance the designer's role when designing space for flexibility with the focal use of building information modelling (BIM) and design standardisation. An exploratory study was conducted using a questionnaire survey. The questionnaire was piloted to a Web-based Group (48 responses) and then it was distributed to the top 100 UK architectural firms (10 responses) based on the Building Magazine, (2010). Both descriptive and inferential statistics were used. The questionnaire survey included both open ended and close ended questions. The paper provides empirical insights about how design standardisation and flexibility can be applied with BIM. It suggests that embedding flexibility can be enhanced with BIM by supporting the generation of different design options and scheduling design tasks with different information attached. The results also showed that strategies such as “adapting,” “contracting” and “expanding” are more beneficial than other flexible strategies. Regarding standardisation and flexibility, the results showed that although standardisation is not the panacea of providing flexible solutions, it is indeed applied and applicable in construction projects that require flexibility. The chosen research approach measures, records and reports the perceptions and worldviews of the respondents. Therefore, the research findings are based on how reality is formed by the participants and their experiences. With that in mind, the information identified was used to draw some noteworthy findings that provide detailed information on embedding flexibility in healthcare buildings

Barriers to effective use of CAD and BIM in architecture education in Nigeria

This study investigated barriers to the effective use of CAD/BIM in response to the dearth of data from Nigerian schools of architecture relative to information obtained from practice. This is important to bridge the gap between skill sets required in practice and those obtained from architecture graduates. Objectives of the study were to establish barriers that influence effective use of CAD/BIM tools in Nigerian schools of architecture as well as to identify means of addressing these barriers within the curriculum from the perspective of students. A mixed methodology was employed via questionnaire responses from 64 MSc students at the department of Architecture, Ahmadu Bello University Zaria as well as suggestions for improvement. Quantitative data were analysed in SPSS v. 21 for means (M) and Relative importance Index (RII). Suggestions proffered by respondents were assessed using content analysis. Results reveal that requirements for high computer specifications (RII=0.92), expensive cost of computers (0.91), requirements for intensive training (0.81), inadequate integration within the curriculum (0.81), lack of steady power supply (0.77) and time to master skills (0.76) were the most important barriers to effective CAD/BIM use in architecture education. Overall, government and institutional related barriers recorded the highest means (M 3.68 each). The study recommends government action via policies supporting clear BIM standards, local manufacture and assembly of hightech computers to mitigate importation costs as well as added funding to higher institutions to augment research, power supply and ICT facilities. At departmental level, CAD/BIM tutorials should be integrated within studio sessions as seminars from 200L. At 400L and MSc levels, studio should support collaboration with students from other allied professionals. Recruitment requirements in future also need to include CAD/BIM proficiency to improve quality of teaching staff and learning experience of students

The use of refurbishment, flexibility, standardisation and BIM to support the design of a change-ready healthcare facility

Healthcare in the UK is a very important sector; it provides state of the art accommodation that meets the need of patients, visitors, medical professionals and other staff. The UK Government is currently cutting costs within the different sectors of the economy, while there are raising figures in UK National Health Service (NHS) spending. These are due to a growing and ageing population, advancement in modern healthcare delivery and special needs for different facility users. There is a UK Government proposal set out that requires the delivery of £15-20 billion in efficiency savings over the three year period from 2011 (Department of Health, 2010-2015). This study has understood that cost savings can be achieved by adopting and implementing a framework that supports refurbishment, flexibility, standardisation and Building Information Modelling (BIM). These cost savings can be achieved through Mechanical Engineering and Plumbing (MEP) clash detections using (BIM). 65% of hospital designs are centred on MEP services (interviews). The NHS needs to save cost when responding to possible future changes without compromising the quality of standard provided to the public. A change-ready healthcare facility is proposed to address the issue of change and the design of quality spaces that can enhance effectiveness and efficiency in the delivery of health and social care. A change-ready healthcare facility can be described as a facility that accommodates known or proposed future changes creating novel pathways to increase the quality and life span of facilities. There is also a large chunk of NHS estates that is underutilised EC Harris, (2013). Therefore, healthcare facilities need to respond to future changes in order to optimise their spaces. To achieve quality and cost efficiency in healthcare buildings, key considerations are refurbishment and reconfiguration, optimisation of flexibility, maximising standardisation and implementation of BIM. This research explores opportunities to save costs, time and improve quality of healthcare facilities by making emphasis on the design delivery process. Therefore, the new RIBA Plan of Work 2013 was used as a mechanism to help translate ideas into physical form and yet has been hindered by lack of development and ability to keep up with technological development such as BIM. This is the rationale for developing a framework. The RIBA Plan of Work is accepted nationally. Due to the UK BIM mandate by 2016, this research is focused on the use of BIM to support both space standardisation and space flexibility within a refurbished or new building. Space is a vital component competent in every healthcare facility. It provides the environment for healthcare services to be performed, and links one functional space to another, it can be designed for multifunctional usage. Healthcare spaces are complex entities due to the range of services and technology they support and the number, variety and quality of requirement combined with a rapidly changing environment. Flexibility enables a facility to easily respond to changes, while the introduction of standardisation supports staff performance by reducing the reliance on memory which will reduce human error. But the main question that emerges from current literature is how healthcare designers and planners manage healthcare spaces that cannot easily be standardised due to the constraints of existing structures, diversity in patient and staff needs? With analysis of different flexibility frameworks in the Architecture, Engineering and Construction (AEC) industry, there is a need to improve the existing frameworks. Therefore, a framework for designing a change-ready healthcare facility was developed through a sequence of data analysis starting with literature, preliminary data, questionnaire survey and interviews. Three frameworks for designing a change-ready facility were revised, organised and merged to produce a state of the art framework. Three frameworks were revised as different research methods were required. The successful framework can guide the design process of embedding different flexible design options for a defined project brief to save costs and improve design efficiency. The framework was validated with some of the top 100 architectural practices in the UK, NHS Estates, facility managers and the RIBA through an interview process. Further research and development arising from this research focuses on the process of applying BIM to record or identify key decisions taken for each of the different design options generated from a single brief to inform the designers, clients or other stakeholders involved while collaborating. Findings of this research are described in five peer-reviewed papers. The only certainty in healthcare is change Gressel and Hilands, (2008)

Health and Care Infrastructure Research and Innovation Centre final report 2014

Improving healthcare, while containing costs, demands sophisticated understanding of three core elements in healthcare systems: infrastructure, technology and services. Their tripartite relationship is extremely complex, not least because the pace of change for each is different. That creates considerable challenges in planning for future needs and makes the management of innovation and change difficult. [Continues.

The Integration of Architectural Design and Energy Modelling Software

Intelligent and integrated architectural design can substantially reduce carbon dioxide emissions from energy used in buildings. However, architects need new tools to help them to design enjoyable, comfortable, attractive and yet technically rigorous, low energy buildings. This thesis investigates, by means of a Research Through Design approach, how architectural software could be better designed to fulfil this need by the integration of design, energy simulation and decision support systems. The problem domain of the design of buildings with very low energy requirements was analysed. Two case studies were employed to investigate the limitations with current software. User and domain software requirements were recorded and analysed. Conflicting requirements were noted, in particular, dichotomous views of the building model. An investigation was carried out into the different interoperable standards that result in these views and rules on how to compose the building model as a series of Intelligent Spaces proposed. The Intelligent Spaces would be abstract volumes, enclosed by zero thickness surfaces, which have data and rules attached. Early prototyping of integrated software was carried out by means of a series of sketches and diagrammatic examples. The novel feature of the proposal is that it maintains both an abstract and detailed version of the building model through all stages of the building design and use. Key features of the proposed software are: 1) the ability to move iteratively between sketch to detailed design to explore different approaches to the building form and construction, 2) the setting and monitoring of relevant energy targets throughout the different building design stages and 3) the integration of an advisory system linked to energy targets to support decision making. This space based approach to the software has the potential to provide a ‘designerly’ front to the sophisticated processes of a Building Information Modelling environment

A study of the concept of future-proofing in healthcare building asset management and the role of BIM in its delivery

This research assessed the concept of future-proofing (FP) as a proactive initiative for enterprise asset management is an urgent need against uncertainty, particularly in health care due to unforeseeable demographic shifts and rapid advances in medical technology. Building information modelling (BIM) is a data-driven initiative but a rigorous analysis will indicate that a synergy exists. A multiphase design methodology was adopted to cover as much breadth and depth around the synergies that exist between future-proofing and BIM both in terms of delivery (supply chain) and in an enterprise context (organisational structures). In the first phase, an exploratory survey was conducted. The exploratory data were gathered to include responses of industry experts. The findings provide valuable insights regarding the integration of flexibility and design standardisation and whether this integration can improve change-readiness in designing future-proof healthcare facilities. Then, a first round of primary and secondary case study data were gathered from a major public asset owner organisation. The findings focused on the governance of BIM and FP in an enterprise context. As such three agendas emerged, namely government, strategic management and, due to the opportunities that BIM brings, information management. Then, a second round of primary qualitative data were collected and a series of interviews were conducted. The interviews targeted the opinion of leading industry experts across all phases of a project. At this phase the aim was to develop a classification ontology of the interactions between FP and BIM during project delivery. Finally, the findings were triangulated. As such, a reference model was developed, concentrating on the functional and organisational aspects of the core business of a service organisation. Finally, the three types of findings were connected to give a deployment plan for future-proofing asset management taking into account adoption of innovation which service providers can use to manage their assets across an enterprise

Creativity with Building Information Modelling tools

Whilst the application of BIM continues to be acknowledged and prevailing, design practitioners and academics find themselves in a paradox with an on-going discussion on the impact of BIM tools on design creativity and innovation. Literature suggests that BIM tools can hinder design creativity due to: parametric limitations; interoperability; and the demand for detailed information at preliminary design stages. However, other literature shows that BIM tools increase design creativity, and at some point provide limitless opportunities to be creative. The aim of this paper is to identify and verify the impact of BIM tools on design creativity. It is important for architectural students and practioners to be aware of the impact of BIM tools on the design. A literature review was used to identify the benefits and constraints of BIM tools on design creativity; a questionnaire survey was used to verify its impact. The questionnaire survey was conducted with the top 100 UK architectural firms (group one) and CNBR Yahoo Group (group two). It was found that BIM tools do not affect design creativity and innovation in the opinion of the respondents. This paper enlightens the status-quo of BIM tools on creativity and innovation, but will focus on the impact of BIM tools on architectural design creativity in the early design phase more closely. This research would be important to both academics and architectural designers using BIM in their various applications
