BIM adoption around
How far are we?
All around the world, implementation and usage of BIM occurred in the 1990s. However, the US started earlier – since the 1970s. Many state departments have established their requirements and published them to symposiums such as the National Institute of Building Sciences. But there is no relationship between these standards – they are discovered independently. In 2003, the GSA (US General Services Administration) afresh a formula of the National 3D-4D-BIM Program. This program provided policy mandating BIM adoption for all Public Buildings Service projects.Recently, the US government has released a proposal that includes $200 billion in federal money over the next decade to incite an additional $1.3 trillion in spending from cities, states and private associations on sizable infrastructure projects. The US is one of the largest global markets with output reaching over 1.1 billion US dollars in 2017.
First made BIM as a public mandate in 2005 in Norway and then in 2007 in Finland and Denmark. Like the GSA, they were also focused on controlling initial costs. But on the other hand, other factors were important for their adoption as well, including valid investment at the national government level in innovative technologies, the potential of BIM to persuade to better-performing buildings and lower energy costs, interest at the nationwide level in becoming innovation leaders and global commanders in the building industry.
The Government declared the arrangement of the Digital Building Platform – BIM task group conceived by several industry-led organizations to develop a national BIM system. The government is playing an enormous role in BIM promotion and is all set to make it mandatory for public infrastructure projects by 2020.

What are the benefits
of a digital twin for
the real estate?
A digital twin is the next stage of real estate innovation. The answer comes to light from the benefits it brings – immediate and long-term. It brings savings on maintenance costs, makes the building more sustainable and raises the living standards of tenants.
Speed up decision-making Through cloud solution allowing building owners and operators to access the virtual twin any time and make use of the statistics.
Reduce maintenance costs by easing labor costs related to facility management – the technology will help the specialist to identify the fault location via tablet/smartphone and understand exactly what the problem is.
Create an ecosystem of buildings with the possibility to deploy a single application across a range of properties – digital twins will forecast the impact of buildings on one another.
Increase user satisfaction by timely troubleshooting and improved customer service for tenants.
Foster sustainability with the possibility to deploy a single application across a range of properties – digital twins will forecast the impact of buildings on one another.
the building lifecycle
is so vital?
The future of the building lifecycle is based on BIM solutions which provide saving time and money not only during design and construction but in the management phase as well. In the area of lifecycle costs, it gives us the possibility to:
re-use building models and data to better manage facility operations
analyze data-rich models to optimize resources and reduce waste as well as lower lifetime maintenance and operation costs
use intelligent 3D models to help manage space and perform spatial affirmation for occupant chargebacks
The Facility Manager is no longer responsible for simply “changing light bulbs” or for maintaining elevators but is an active part of a new culture of collaboration, environmental sustainability, information sharing and innovative initiatives.
For whom BIM is useful?
In Europe, more than 80% of buildings were built before 1990 and most of them do not have building documentation in BIM format. Incomplete, missing or outdated information in existing buildings results in inefficient management of time and resources, therefore increasing the cost of maintenance and renovation processes. To bridge this gap, as-built documentation can be generated through the process of Scan-to-BIM to recapture building information in BIM format.
BIM can be beneficial to the stakeholders in all design phases. In the case of existing buildings, it has numerous potential benefits, especially when it comes to the lifecycle of a facility. The design and construction phase contributes to only 30% of costs, whereas the operation and maintenance phase averages around 70% of the total life cycle costs. Life cycle cost analysis (LCCA) through BIM can be used to evaluate the economic performance of the building over its entire lifetime. When focusing exclusively on cost reduction, the life cycle costs of different design alternatives can be compared to understand and identify the most profitable/economic design configuration.
“Moreover, according to The Stanford University Centre for Integrated Facility Engineering’s report on a study of 32 projects from across the US, Europe and Asia, BIM could increase the accuracy of cost estimation up to 3%, eliminate up to 40% of unbudgeted changes and reduce the time taken to generate cost estimations by 80%.”
Save money & time with BIM
The majority of financial benefits in renovation projects can be achieved through increasing the energy performance of the building. According to a study by The Boston Consulting Group, digitizing the building sector by using BIM to conduct a building-wide energy analysis can save up to 20% of energy costs. This number increases when looking at renovations of older buildings because of their traditionally energy-inefficient nature. Using BIM for building energy analysis in these situations helps improve energy efficiency and reduce material waste, as it helps to identify areas of improvement. Additionally, energy and water requirements can also be determined resulting in better optimization and reduction of overall life cycle building costs.
A well-maintained BIM model can help designers and engineers to evaluate the likely impact of major repairs and retrofitting, by accessing detailed information on previously used materials, such as identifying the optimal recovery options for demolition waste. One such example is Belmont House in Guisborough, UK. Belmont House comprises of three floors measuring over 4100 square meters. By capturing and using data of the existing structure and integrating it with the design for refurbishment, it was possible to re-use approximately 70% of the existing structure. BIM optimized the adaptation of the original building and reduced a significant amount of waste in the process.

In the construction industry, the concept of a single source of truth is the practice of storing project information in one place without duplication, specifying a clear path that leads to the required sets of data. Unlike just documentation, SSOT eliminates potential issues of misinterpretations and disorganization. SSOT is a necessity in the construction industry, mostly because inefficient management and low level of collaboration are major obstacles when dealing with existing buildings and can impact the project negatively as high as 60%. (Smart Market Brief: BIM Advancements)
Creating a digital replica or “Digital twin” of a built asset provides significantly valuable information to all stakeholders to enable a single source of information, to improve trust and transparency.
SSOT reduces the fear factor of moving forward with the wrong information. According to the Centre for Digital Built Britain (CDBB)(2019), the digital twin of physical assets helps organizations to make better-informed decisions, leading to improved outcomes; for example, meeting tight deadlines, improved quality of construction while staying in budget and reduced rework. BIM provides platform compatibility with integrated project planning which has had a major impact on the speed of resolving design issues and clashes - which reduces construction delays, saving both time and money.
BIM has changed the way the AEC industry works, by creating a digital format for the interoperability of information during the life cycle of a building. Which also includes renovation, addition and demolition, operation, and maintenance of a facility. BIM promotes O&M through virtual models, that function as a single source of information produced and refined during different phases of construction. This correlation of data allows BIM to avoid conflicts that usually occur due to the lack of coordination between the project´s teams, providing better results and reducing risks that translate into time loss and money. Collaborators can also open up to new possibilities to make O&M of the facility more efficient by merging data sets from multiple sources and creating a smart system.
By making intelligent use of BIM integration into the building’s asset and facility management system and using this combined resource, NTT Facilities, a Japanese building service provider company reduced an estimated 20% on O&M costs. This approach was used considering the inspection, repair, and maintenance of the company’s R&D premises. Another smart technology is the augmented-reality; important information can be accessed on-site with the help of AR by superimposing a BIM model over the actual view. Interaction between the real and the virtual world can help to identify hidden or missing features on-site such as, electrical and mechanical components, maintenance and repair manuals, etc.
”VINCI Facilities has already found that BIM helps achieve time savings of up to 40 % on tasks such as retrieving documents, tracking equipment to be inspected, or checking stocks of a spare part.”
“Although the AEC/FM industry is in the early days of BIM use, significant improvements have already been realised – compared to traditional 2D CAD or paper-based practices”.
Going from a model – BIM model - to Facility Management
Major destruction for Management is researching for information, identify where the data is, bringing the correct place of equipment out – it consumes most of the time for workers. The most important thing is to keep the data electronically. In this way, we can obviously reduce the manual data entry, make sure that the data transfer is controlled as well as always stored in correct places, and that is reducing time, consequently, costs of the entire process.
Microdesk has looked at the numbers of different examples with their customers to see the benefits of implementing BIM for operations in comparison to usage of a typical FM process (table above). We can directly see the conclusion. Without the use of BIM, we waste time (money) on every step. Let´s look on the example of Asset Information Entry and Update – e.g. locating necessary information for making repairs took a significantly longer amount of time – the difference was up too 1616 hours. Through the BIM model integration, facility staff have access to information that a traditional asset management system could not capture or was not easily accessible. Furthermore, around studies of Microdesk with their clients, they have found that the combination of BIM and FM helped to achieve a net 5% savings in annual operations expenditures.
