BIM 2020 REPORT NEW ZEALAND

[1]

The New Zealand BIM Acceleration Commission has issued the seventh edition of the report on the application and future of BIM in the country in 2020. BIM in New Zealand [2] - a look at the entire industry in 2020. The most important quotes are below:

This seven-year series follows the industry scrutiny of large and influential organizations in the New Zealand built environment, monitoring progress in BIM adoption. This year, the control group has been expanded to compensate for changes in the construction industry in New Zealand. For the fifth year, we also conducted a customer survey focusing on asset owners and managers to better understand the progress of BIM in facilities and asset management. A separate study of the use of BIM by subcontractors was also conducted. The BIM Acceleration Commission has just completed two full three-year terms and is in the first year of another term. During this period, the overall proportion of industry projects using BIM in New Zealand increased from 34% to 68%.

"Not fully accepted in the industry, which means it's easier not to do by default." (INDUSTRY) "Consultant Compliance. Failure to understand what is required / required. No industry skills. "(CUSTOMER)

• Quiet operation - BIM is not designed with the entire supply chain in mind
• 57% of architects, designers and engineers make BIM available externally
• 29% of subcontractors make BIM available externally
• 60% of subcontractors have to reject and remodel the BIM model design
• 27% of customers say they don't use BIM because their supply chains can't do it

"Subcontractors are not that familiar with BIM, so it's difficult to get them to work in a BIM environment during construction." (CUSTOMER) (...) "Subcontractors are not that familiar with BIM, so it is difficult to get them to work in a BIM environment during construction." (CUSTOMER) (...) “The quality of the design models is not good enough to be used in the production of production models. Production models are often rebuilt from scratch. (SUBCONTRACTOR)

Misalignment Points: Industry • Does not design for the supply chain • Not all operate at the same level (unequal use and skills, different data environments and file types) Subcontractor • No use and / or skills across the community • BIM is not expected from subcontractors • Much rework is required to utilize design models Customer • Stuck with legacy systems • Underfunded and underfunded • I don't see the benefits • BIM is not procured This difference in use may degrade some perceptions of the value of BIM as the Design-Pond-Build model ”Means that the main cost of using BIM (occurring in the design phase) is decoupled from most of the benefits in the construction phase. It takes a lot of time and effort to develop a "single" design model that will move to a "as-built" model. Given the small number of customers using BIM to populate their commonly used legacy systems, is this really a costly 'one size fits all' design effort? Given the myriad needs and applications of the model in a project, would a better BEP benefit from the 20:80 rule (20% of the effort realizes 80% of the benefits)?

BIM Application - Industry and Customer Groups: Both the industry and customer groups were asked about the current use of BIM. Almost everyone in the industry group has used BIM in the last 12 months (98%), and 88% plan to use BIM in the next 12 months, indicating that some who are using BIM now do not plan to do so in 2020. in the industry group, two-thirds of all projects (68%) use BIM in some way. In 2020, an industry group was asked how they actively use BIM. Eight in ten (80%) say they are actively pushing the use of BIM in their projects, and another 20% say they use it, but don't push it. New respondents to the survey are more active in promoting BIM (86%) than the original study group (79%). Subcontractors are less determined in their use of BIM. 14% of subcontractors say they are actively seeking to use BIM, although 52% say they will use it if it is available.

BIM in the procurement process: Previous research has indicated that the willingness of customers to buy BIM has been a barrier to increasing the use of BIM. The survey was conducted done to customers in 2020. She investigated this in more detail. These questions concern the percentage of projects that define BIM in the procurement process and whether customers needed the model, the data, or both. In 2020, approximately half of all new assets (52%) and major upgrades (48%) have BIM specified in the contract. Whether models, data, or both are ordered by customers appears to be the same for new assets or major upgrades. (...) The inability to change current practices is the main reason customers say they are not using or considering switching to integrated digital spatial resource information (27%). It is encouraging to see a significant reduction in the number of customers indicating "lack of knowledge" as a barrier - from 54% in 2019 to 18% in 2020.

What do industry and subcontractors use BIM for? An industry group was asked where in the project lifecycle they had used BIM in the last 12 months or planned to use BIM in the next 12 months. Usage during the planning phase fell from 71% in 2019 to 63% in 2020. Nine out of ten (90%) of industry respondents use BIM during the design phase and eight out of ten use BIM during the construction phase. Both of these phases have extended from 2019. The low level of utilization in asset and facility management may reflect the fact that a significant portion of the industry group is active in the design phase of the project. In 2020, this question was extended to other stages in the project life cycle. Seven out of ten industry representatives use BIM for early contractor engagement and bidding (73% and 70%, respectively), and six out of ten use BIM for shop drawing stage (63%). A sample of subcontractors shows that among subcontractors in 2020: • 43% use BIM at an early stage of contractor engagement; • 57% use BIM for shop drawings; and • 43% use BIM during the construction phase.

BIM is Most Likely to Grow in Industry: Every year we see great optimism that various BIM applications will grow, although few actions have managed to meet the projections. In 2020, a few of the 26 applications are expected to decrease over the next 12 months: • 3D Coordination • Design Review • Modeling Existing Conditions • Creating a Project • Modeling Records. Phased planning (4D modeling) is predicted to bring the greatest growth in 2021. In addition, asset management is predicted to increase significantly to 60% of all projects. While we saw a slight increase (from 37% in 2019 to 45% in 2020), the projected increases we see in each previous year have not been realized. Given that the industry group is mainly sampled by consultants, this can be difficult to predict for them.

Customer Account for "Lifetime, Entire Building" Costs: More than seven out of ten new assets (73%) and two-thirds of major refurbishments (67%) include at least some of the lifetime, total construction costs. In 2019, the ratio of construction costs to 'whole life, whole building' costs was quite mixed. However, in 2020, we see a more balanced mindset - 41% of those building new assets say they are on par (and 30% of those working on major upgrades).

Comparing industry and subcontractors on the benefits of BIM: When comparing responses from industry and subcontractor groups, there is agreement on most of the positives of BIM - better coordination, clash detection, and cost and resource efficiency. The most noticeable difference between the two is the nuance in the industry group's response. They are able to explain the impact of this performance or coordination, while subcontractors are more likely to just specify the results but not what it means at a later stage. There may be the potential to take subcontractors' awareness of the benefits to a higher level so that BIM becomes more embedded in what they are doing. It's not just accuracy, it's accuracy, which then has some impact on the subcontractors' activities.

Industry: Not all parties are on board or in alliance are the main concern. In 2020, there were many comments regarding staff training and experience on platform and file type issues, client preparation and customization, and cost / value perceptions. • Not all sides agree, on board or at the same level (mentioned by 28% of participants) • Customer readiness, alignment and knowledge (mentioned by 23% of participants) • Staff training and experience (mentioned by 20% of participants) • Problems with platform and file type (mentioned by 15% of participants) • Costs and values ​​of using BIM (mentioned by 10% of participants) (...) Costs and values ​​of using BIM: “Not understanding value at the customer level. The cost of implementation is seen as a double decrease according to customers in the work that should already be allowed. The lack of complete industry adoption means it's easier not to do by default. The end results must include lower construction costs and higher quality - the BIM community is yet to make that stronger. " “The cost of constantly changing drawings, the cost of additional calculations. Too little time allowed the construction drawings to catch up on the architectural backlog. The architect will change the design and structure, always trying to catch up on deadlines, which leads to rushed work, long working hours and mistakes. "Traditional tolling arrangements are still not suited to BIM manufacturing programs. Consultants do not allocate BIM resources early enough in the workflows. "

Subcontractors: Respondents from the group of subcontractors were asked about the barriers in using BIM. Responses were grouped according to the main topics: 1. Need for wider use and better understanding of BIM in the industry (and how to make it work for other parties) - indicated by 33% of participants 2. Weak models, information and interoperability of platforms - mentioned by 24% participants 3. Lack of training and knowledge (or access) - indicated by 18% of participants. (...) Weak models, information and platform interoperability: “Broken information flow due to contract requirements. ie there is a requirement that services provide detailed models for coordination, but architectural and structural elements are not modeled well enough to ensure good coordination. The quality of the design models is not good enough to be used in the production of production models. Production models are often rebuilt from scratch. “Consultants are using the wrong families and putting on the wrong equipment. A real hardware ECI has problems with space. " “Seismic data and fastening systems are not shown on the model. Variants are not added to the model ”. "No Hydraulic Calculations for New Zealand Fire Trade"

Customers: Customer comments on the barriers to use of BIM focused on three main issues: • Internal capabilities (mentioned by 43% of customers) • External opportunities (mentioned by 26% of customers) • Cost and perceived value of BIM (indicated by 24% of customers)

What is needed to increase the use of BIM by industry and customer groups? Respondents from industries were asked what should be changed to make their company use BIM more often. In 2020, 35% of participants didn't say anything - they were already using BIM in all their projects. This represents a strong increase from the 23% who said so in 2019. In addition, the main points raised in 2019 included comments about changing the way we think about products and orders, more skilled workers and government leadership. In 2020, Comments focused more on customer acceptance, especially the cost of getting good results and understanding the value of those results. Better quality and more aligned files and platforms were also a problem - and misalignment increased the cost of BIM. In addition, as in 2019, there were comments on staff training / upgrading, as well as greater use and involvement of consultants and contractors. More contractors using BIM, especially prime contractors, and more cross-industry collaboration (mentioned by 33% of subcontractors): "Mechanical contractors need to involve subcontractors more." "Greater collaboration among other industries." “We discovered benefits when prime contractors have BIM enabled and see BIM as a construction tool, not just a 3D model for creating 2D drawings. More prime contractors involved in BIM will see greater use of BIM and a greater variety of applications. We also see that customers who request as-built BIM models with embedded asset information do not know what to do with them. The current required resource information is often a duplicate of what is found in the operation and maintenance manuals. This limits BIM to only what has been installed. A better understanding of what information is required may be more useful if it is included in preventive planning and maintenance systems. "" Prior involvement of subcontractors in the design. "It's just that more workplaces are taking advantage of it and make it available for use early enough to be helpful." "ECI and all on-board transactions." More consideration of BIM in customer purchasing and use outside of construction (mentioned by 19% of subcontractors): "A BIM model would have to be handed over to the facility management team so that we can use it for ongoing service / energy management / green star activities." "Education in the field of purchasing methods." “BIM is gaining ground, being driven and managed from design to construction to completion and more about". “This needs to be specified at the bidding stage and across all industries to collaborate on the model during construction. It should be enforced. Industry respondents talk about customer acceptance and platform and file interoperability, while subcontractors focus on increasing the number of contractors using BIM and customer orders. As a result, subcontractors are now focusing on areas that were important to the industry four years ago. This suggests that subcontractors are currently 3-4 years behind the industry in the adoption curve (unless we do something to speed up adoption among subcontractors).

Sharing BIM Execution Plans (BEPs) In 2019, less than half (46%) of the subcontractors surveyed at least occasionally received BEPs on projects where consultants used BIM. In 2020, that number rose to 57%, although no one said they "always" receive a BEP when a consultant has used BIM (it was 14% in 2019). Both industry and customer groups report not working with industries. This data confirms that BIM information is not consistently shared with all parties involved in a project. Subcontractors who received BEPs were asked to rate the BEPs they received based on several factors. Most agree that the BEP clearly explains roles and responsibilities, clearly explains the methods of cooperation, and provides enough detail. There is less agreement that the BEP was useful in scoping or that it accurately represented the use of BIM in the project. Only four out of ten agreed with each of these statements.

BIM Handbook: This question was about the awareness and use of the NZ BIM Handbook. More than four in five industry representatives both know and use the NZ BIM manual. For architects / designers and engineers, this percentage increases to 100%. People classified as "other" (project managers, quantity appraisers, etc.) make less use of the handbook. Subcontractors reported that 19% of them know and use the NZ BIM manual.

View from industry and subcontractors on the role of government as a customer: Industry respondents were asked about the importance of government as a customer in accelerating the development and use of BIM in New Zealand. More than three in five (63%) in 2020 say the role of government as customer is at least 'very important'. This has been stable since 2019, although in 2020 we see a higher percentage of statements that government involvement is "essential". Among subcontractors, only 14% say the role of government as a customer is critical to accelerating BIM. In fact, 33% say using and accepting BIM is harmful. This suggests that industry and subcontractors have very different experiences with government use of BIM.
