I understand that The British University in Dubai may make a digital copy available in the institutional archive. The relationship between national BIM standards and the speed of BIM implementation in the respective countries is also evaluated.
Research Background
With the introduction of BIM in the project workflow, all the building-based information and central model can be shared as a single database for all the disciplines. Adapting BIM workflows on site will ensure the proper documentation of any design changes made on site.
Context Issues
Clash detection and design issues sorted before actual construction takes place on site will ensure time and cost reduction. Therefore, a correct information model containing all 'As - Built' data can be stored in the client or authority archive library for future reference, design changes or extensions to the project.
Research Questions and Objectives
Any change in components or design as a whole will be updated in the cost calculation of the project by the automated counting mechanism in BIM. The green line in the above graph clearly represents the cost effective nature of the BIM workflow. Green building analysis combined with BIM has been shown to provide various benefits such as GBA score estimation, application document management, and overall improvement of the efficiency of the GBA process. (LuY, Wu Z, Chang R, Li Yongkui, 2017) The environmental impacts of building construction are reduced by the introduction of BIM and its subsequent waste reduction methods.
The primary of which is the lack of an effective BIM standards for green buildings.(LuY,WuZ,ChangR,LiYongkui,2017) The collaboration of design BIM model with energy analysis model is essential to produce adequate green building models that meet green completed. building standards. The role of BIM in each specific stage of the project life cycle is briefly discussed above. India – One of the developing countries, which is in the early stage of BIM adoption.
This shows the relatively new nature of the concept of BIM in the construction industry. Half of the respondents were only 2-5 projects old in adapting BIM to their project workflow. Figure 5.16 shows respondents' thoughts on the time frame required for the major BIM implementation in the UAE.
This can be attributed to the recognition of the advantages of BIM workflow over traditional workflow.

Half of the respondents think that it will have a positive impact on the large-scale adaptation of BIM in the country. Figure 5.20 and Figure 5.21 show respondents' opinions on the applicability of BIM to sustainability and the overall reduction of construction waste in the industry.
BIM IMPLICATIONS IN DIFFERENT STAGES OF A PROJECT
BIM in Co-ordination Review
Project coordination between disciplines has also been found to increase with the introduction of BIM into the workflow, which allows users from different disciplines to perform individual analyzes according to their calculation methods and enrich the central model with design data at the same time. time. Once the amount of data reaches a certain limit, the models seem difficult to handle.

Research Gap
The levels of BIM range from level 0 to level 3, which indicates the maturity level of the BIM model. Figure 5.8 above shows data on respondents' training methods in relation to BIM. More than half of the respondents believed that BIM is responsible for taking more time in the detailed design phase.
Figure 5.15 shows the respondent's self-assessment of the BIM mandates set by the relevant authorities in the UAE. High initial expenses are another major concern due to the cost of BIM software and training requirements for it. Some of the opinions involve making strict regulations on the submission of BIM models in the municipality for projects of all scales.
METHODOLOGY
Research Strategy
For the first phase of the dissertation, the difference between the traditional workflow and BIM workflow is assessed by having a step-by-step division of the typical BIM workflow into construction engineering projects, which usually turn out to provide optimal design and efficiency. For the second phase, 5 countries are selected in relation to the connection between the current BIM adaptation status, Implementation strategies, authority mandates and national BIM standards/guidelines. UAE - One of the most thriving construction industries with a history of adapting to the latest technologies.
Of the 5 selected countries, 3 have recognized national BIM standards, approved by their respective central governments. The relationship between the development of national BIM standards and the BIM adaptation in the respective countries is analyzed. For the third phase, a market survey was conducted to understand the current BIM status in the UAE and the need to establish national BIM standards.
Data Collection
The use of BIM in the UAE was already on the rise before this term. None of the respondents mentioned any project (that they were a part of) in the rest of the Emirates that used BIM methodology. Figure 5.6 and Figure 5.7 show a comparison between actual construction experience and BIM experience of respondents.
More than a quarter of the respondents felt that the lack of general awareness about the difference between traditional 2D-based CAD workflow and the BIM workflow is the major obstacle in BIM implementation. But the early recognition of the potential of BIM by the government and implementation of BIM mandates and standards across the country can be found as the positive impact of BIM adoption in the country. The need for a large-scale BIM implementation strategy across the UAE was expressed by most of the respondents.
BIM APPROACH FOR STRUCTURAL PROJECTS AND CASE STUDY
BIM in Schematic Design
After the LOD 100 phase, the project is shaped into a LOD 200 phase, which can be invented as the schematic design phase in normal project standards. The initial coordination of the positioning of the building elements and the BIM protocols to be considered for the desired design result should be decided at this stage. Analysis data, such as the sizes of structural parts, are incorporated into the structural BIM model.
Possible design alternatives and building materials are considered and BIM models are updated. The initial building materials and quantity plans are made and analyzed according to the requirements of the architectural plan. Initial coordination models are set up and examined for potential major design clashes or conflicts between disciplines.
BIM in Detailed Design
Upon completion of the construction project, a proper survey of the site should be performed to verify that the structural elements assigned in the BIM model match the "as built" condition. BCA released the Singapore BIM Guide in 2012 detailing the BIM execution plan using BIM specifications and BIM modeling and collaboration methodology. Projects in Abu Dhabi also have an increasing demand for BIM considering the rest of the Emirates.
But the growing number of personnel using BIM workflow and methodology shows the growing trend of BIM adaptation due to various industry factors and requirements. Structure detection/splice models such as LOD 350, LOD 400 and LOD 500 account for just over a quarter of common BIM usage. Figure 5.17 shows respondents' thoughts on establishing a national BIM strategy in the UAE, similar to industry pioneers such as the UK's BIM level system.
Contractors' unwillingness to bear the additional costs of BIM implementation and hiring of BIM staff are also marginal concerns. Figure 5.19 shows the respondents' preferences for the scale of the construction projects where BIM workflow would be preferred by them. A small percentage thought that it is likely that BIM also contributes to the reduction of construction waste if it is used correctly.

BIM in Project Completion Stage
Upon completion of construction, the contractor or a third party surveyor must assess the 'As Built' condition of the project and create a LOD 500 model with all relevant information on the structural elements and the analytical data for future renovations and demolitions produce. Properly manufacturing this model will ensure minimal wastage in future developments and also make the construction future automation ready. Final coordination reviews should be carried out to obtain all relevant data from all disciplines and it matches the site conditions.
Ensure that all manufacturing details, such as service life cycle care details, warranty time, etc., are entered and coordinated in the BIM model for all building elements and components. If required, general models should also be developed so that all interested parties have a proper control over the construction and all technical information. The client must ensure that all data, including analysis and design information, is incorporated into the final BIM 500 model delivered to it by the contractors.
BIM in Project Facilities Management Stage
Their report is often found to provide information on the level and percentage of BIM adoption in the country. This will be instrumental in the large-scale application of BIM in construction projects in India. The figure 5.5 shows the location of projects in the UAE that the respondents were part of, which used the possibilities of BIM and BIM workflow.
Phase of a project that turns out to consume more time when integrating BIM into the workflow. Phase of a project that turns out to consume less time when integrating BIM into the workflow. More than a quarter felt a very high contribution to sustainability by the correct implementation of BIM in the project workflow.
The use of BIM technology based work has increased among consultancy firms and contractors in the UAE.
