Building Information Modelling (BIM) is increasingly deployed as part of the processes in Architecture, Engineering and Construction (AEC) industry projects. While the benefits of BIM have been extensively proclaimed, explicit justification in terms of direct cost savings for BIM implementation on real-life projects, particularly for clash detection BIM workstream, are not well documented. This paper proposes and demonstrates a methodology to prove how BIM-based clash detection leads to cost savings. A schema is developed based on literature review and industrial expertise to quantify cost savings achieved by the utilisation of BIM-based clash detection and resolution. This paper provides validation of the proposed schema on a major infrastructure project. The developed schema includes the categorisation of identified clashes based on stakeholder involvement and required actions. The validation used the estimated cost of clashes were those not resolved before site operations took place. This schema simplifies both the categorisation and cost estimation of clashes in design. Estimated savings yielded 20% of contract value using the schema, for the multi-million-dollar project case study, thus extending evidence of BIM savings and benefits. The schema improves the existing process and valorises clash detection, thus allowing stakeholders to conduct a cost-benefit analysis. In addition, the categorisation methodology allows prioritising on the most costly clashes, and draw lessons learnt for further projects. This schema opens the path towards a systematic methodology to appraise the benefits of different BIM uses or processes.
Part 4: Building Information Modeling (BIM)International audienceEmployer’s Information Requirements (EIR) is a key document for the successful delivery of construction projects using Building Information Modeling (BIM). EIR sets out the information to be delivered and the standards and processes to be adopted by the suppliers as part of their project delivery approach. The concept of EIR has been developed by the UK BIM Task Group as a holistic framework for the UK construction industry to deliver the UK construction client requirements in projects using BIM. It includes a set of requirements and guidelines in three macro areas namely, technical, management and commercial. EIR, which are specific to the construction industry in Qatar, do not exist yet despite BIM is increasingly adopted across the Qatari construction industry. However, construction projects using BIM in Qatar adopts various aspects in technical, management and commercial areas. In this paper, we analyze the current BIM practice in Qatar and compare the findings against the items of the three EIR’s areas. The overarching aim is to assess the potential of delivering EIR in BIM based construction projects in Qatar. To accomplish this aim, major construction industry players (clients, consultants, contractors), representing a significant part of Qatar construction industry, were interviewed about the three EIR’s areas and their items. The results showed discrepancies in addressing EIR and varied levels of readiness in delivering the different EIR’s areas and items. The paper has proposed general guidelines for delivering EIR in Qatar which are informed by the survey and current international EIR standards
Abstract. Employer's Information Requirements (EIR) is one of the key early documents in projects using Building Information Modelling (BIM). EIR, introduced by the UK BIM Task Group, sets out the general information to be delivered and the standards and processes to be adopted by the suppliers as part of their project delivery approach. It includes a set of requirements and guidelines in three areas namely, technical, management and commercial. EIR, which are applicable to the construction industry in Qatar, are not clearly defined despite BIM is increasingly adopted across the Qatar construction industry especially on large and capital intensive projects (e.g., stadiums, hospitals, rails, roads, museum). In this paper, we aim to develop a set of principles and recommendations for the three areas of the EIR which are applicable to Qatar's construction sector. We start by investigating the currently adopted BIM practices across the three areas of the EIR by interviewing major construction industry players (clients, consultants and contractors). The interview results showed discrepancies and varied levels of readiness in addressing the different areas and items of the EIR. Finally, we propose a set of general principles and recommendations for the different areas and items of the Client Information Requirements (CIR) -an adaption of the term EIR as evidenced in the paper. The proposed principles and requirements were informed by the interviews and validated by administering a questionnaire survey with industry experts.
The research is part of a wider project aimed to develop a whole lifecycle information flow approach enabled by BIM protocols and technologies for Qatari construction industry. We consider the lifecycle information flow as enabler of a consistent and continuous use of building information from design, through construction, to the facility management stage. Building Information Modeling (BIM) is increasingly used by the Architecture, Engineering, Construction and Operation (AECO) professionals around the world. BIM has proven and potential benefits to facilitate Whole Life Cycle (WLC) information flow described above. It is generally accepted fact that AECO industry is fragmented in nature. Using BIM for WLC information flow is seen as one of the potential solutions to contribute towards a more cohesive AECO industry.Within the global construction sector, Qatar's construction market is one of the fastest growing in the world throughout the next decade in alignment with the Qatar National Vision 2030. Currently ongoing and planned construction projects exceed US$220 billion (Kilani, 2014), e.g. Lusail City projects, new Doha Port, new Hamad International Airport, Qatar Rail project, Qatar National Museum project as well as construction of stadiums and related infrastructure projects ahead of the Qatar 2022 FIFA World Cup.This paper aims to identify current BIM related practices, existing procedures, technology and standards being used in Qatar using qualitative data collection and analysis technique and then proposes a framework for BIM processes across whole life cycle of the project to facilitate whole life cycle information flow. 28 semi-structured interviews were conducted with different stakeholders (clients, contractors, consultants) involved mainly in design and construction project lifecycle stages in Qatar. Results of the conducted interview analyses are presented in relation to policy, people, process and technology (3P + T) pillars that have been proposed for use in Qatar.The following key findings were reported by majority of the interviewees (values in brackets indicate the agreement percentage): (Vukovic, Hafeez, Chahrour, Kassem, & Dawood, 2015) Usage of FIDIC contract template (67%) and BS 1192:2007 BIM standards (60%) is prevalent on projects in Qatar. However, specific BIM information/standards should be developed at a government level for the Qatari construction industry (86%), including standard project stages with clear process maps (82%). Also in comparison to the situation in other countries, based on the examined literature, Qatari government should do more to drive the construction industry transformation by undertaking BIM related initiatives.BIM competency is usually a criteria for prequalification and selection during the procurement process (71%).Organizations in Qatar mostly use in-house BIM trained staff (75%).BIM roles are specifically defined in the contract (86%), BIM standards are required by contracts (68%), and should be enforced by contracts (75%).There is no need to create more BIM specific roles/positions (64%), but there is a need to upgrade the skills of people on BIM specific positions (89%). There is also a need to educate other project participants how to collaborate using BIM (96%). Such identified needs are similar to the situation in other countries covered by the literature review.LOD 300 is mostly required in design/construction stages of ongoing projects in Qatar (64%), which is the owners' responsibility (71%). The owner usually also initiates design changes (68%). In alignment with the above findings this paper proposes a framework (Fig. 1) consisting of ‘Project DNA’, BIM Processes and Whole Life Cycle of the projects and their inter relationship. Future work will elaborate on the BIM processes and protocols and validate the proposed framework using case studies.
