What is BIM?

“BIM is a process. It is not a tool or solution. It is a holistic approach to the design, construction and management of the facilities used in the built environment.� (BIFM, 2012)

w14025311 BIM or Building Information Modelling is a process for creating and managing information on a construction project across the project lifecycle. One of the key outputs of this process is the Building Information Model, the digital description of every aspect of the built asset. This model draws on information assembled collaboratively and updated at key stages of a project. Creating a digital Building Information Model enables those who interact with the building to optimize their actions, resulting in a greater whole life value for the asset.


Through BIM, the UK construction industry is undergoing its very own digital revolution. BIM is a way of working. BIM is information modelling and information management in a team environment, all team members should be working to the same standards as one another. BIM creates value from the combined efforts of people, process and technology. (NBS, 2013)

Multi Disaplinary BIM: For many decades, the AEC community has relied on a paper-based workflow with designers working in “silos” that focused on a single project discipline or function and sequentially passing the outputs of their design decisions on to the next discipline. This isolated, sequential process created many barriers to effective collaboration and has often led to misunderstandings and mistakes requiring costly rework in the field. BIM has changed the way that designers, consultants, engineers and contractors perceive the building processfrom prelimiary design to the facilities management. The rise of specialists had made it less possible for designers to design without the aid of specialists. For years the constrctuon industry has been classified as being ‘fragmented’ however the nature of the industry requires a diverse multi-disaplinary team (architects, mecahnical enginers, electric engineers, QS. etc. BIM allows for all the disciplines to work on the same project and add implementations of information required from their diciplines.

BIM Mana The free-to-use NBS BIM Toolkit will benefit both public and private sector construction projects. It provides step-by-step help to define, manage and verify responsibility for information development and delivery at each stage of the asset lifecycle. Developed by NBS specialists and industry partners. giving the members of your project team the power to:

Client and Asset Managers: Comprehensively define information requirements to ensure your needs are met and better project outcomes are guaranteed.

Design and Constrcution Teams: Assemble a team with clearly assigned roles and responsibilities to work collaboratively on your Level-2 BIM project.

Construction managers Provide digital information quickly and easily to specifiers on thousands of construction projects.

Souce: (Monagons 2014)

agement TheToolkit is an integral part of the suite of documents and tools that underpin the delivery of UK Level 2 BIM allowing you to:

Define information requirements Easily produce the information requirements, aligned to specific project stages, for insertion into key documentation such as Employer’s Information Requirements.



Common Data Environment (CDE) The CDE is not just for a place to share geometric information. Other information such as registers, schedules, contracts, reports and model information is all shared, building on the concept of a “federated” model by bringing everyone’s information together in a virtual space. PAS 1192:2 states that for the avoidance of doubt all project information, whether in BIM environments or in conventional data formats, should be shared using a single collaborative data environment.

Manage the delivery of this information: Develop and manage this information through the project timeline using a standard digital plan of work that is built for BIM.

ALISTAIR KELL FROM BDP "The BIM Toolkit will allow the industry to enforce a discipline and rigour across building design and delivery that doesn’t exist at present."



BIM Maturity Levels Level 1 There are currently four levels of BIM under which Building Information Modelling can be classified. At Levels 0 and 1 there is either a lack of BIM or an over-reliance on different systems of data. In April 2016, the UK Government mandated compliance with BIM Level 2 in order to fund any public sector construction project. At Level 2 there is a structure to the data for a built asset which requires collaboration across the supply chain. BIM Level 3 will be defined and targeted once the construction industry has achieved compliance with Level 2.

This is the level at which many organisations are currently operating. This typically comprises a mixture of 3D CAD for concept work, and 2D for drafting of statutory approval documentation and Production Information. CAD standards are managed to BS 1192:2007, and electronic sharing of data is carried out from a common data environment (CDE), often managed by the contractor. Models are not shared between project team members.

Level 0 In its simplest form, level 0 effectively means no collaboration. 2D CAD drafting only is utilised, mainly for Production Information (RIBA Plan of Work 2013 stage 4). Output and distribution is via paper or electronic prints, or a mixture of both. The majority of the industry is already well ahead of this now (NBS National BIM Report 2017).

Benefits BIM level 2 Process Optimised designs Reduced Risk Save time & cost at handover Better life Cycle planning

Reduced OpEx costs Integrated real time assessment Reduced life cycle cost Potential to link with asset tagging




The government has recognised that the process of moving the construction industry to ‘full’ collaborative working will be progressive, with distinct and recognisable milestones being defined within that process, in the form of ‘levels’. These have been defined within a range from 0 to 3.

Level 2 This is distinguished by collaborative working – all parties use their own 3D CAD models, but not necessarily working on a single, shared model. The collaboration comes in the form of how the information is exchanged between different parties – and is the crucial aspect of this level. Design information is shared through a common file format, which enables any organisation to be able to combine that data with their own in order to make a federated BIM model,

Design information is shared through a common file format, which enables any organisation to be able to combine that data with their own in order to make a federated BIM model, and to carry out interrogative checks on it. Hence any CAD software that each party used must be capable of exporting to one of the common file formats such as IFC (Industry Foundation Class) or COBie (Construction Operations Building Information Exchange). This is the method of working that has been set as a minimum target by the UK government for all work on public-sector work, from 2016+.

Level 3

Souce: (STROMA, 2014)

Currently seen as the holy grail, this represents full collaboration between all disciplines by means of using a single, shared project model which is held in a centralized repository. All parties can access and modify that same model, and the benefit is that it removes the final layer of risk for conflicting information. This is known as ‘Open BIM’. Current nervousness in the industry around issues such as copyright and liability are intended to be resolved – the former by means of robust appointment documents and software originator/read/write permissions, and the latter by shared-risk procurement routes such as partnering. The CIC BIM Protocol makes provision for these. BIM UK Target 2019 . Source: (STROMA, 2012)



Existing Buildings The global construction market is forecast to grow by over 70% by 2025. ‘Lower Cost, Lower emissions & Faster delivery’ are three of variables that the 2025 vision is planning in improving. This study will be focusing on the effect BIM has with the as-built environment, looking at the all the uses and proceedures that are required on order to deliver these goals. Given that 70–75% of the UK building stock that will exist and be in use in 2050 has already been built, a significant part of the existing facilities will not have a building information model till the next major refurbishment. This creates a major gap in the built environment, when it comes to having BIM for existing buildings.

Industrial Strategy 2025: Government and Industry in Partnership Although it would be ideal to have as-constructed asset information model available for every building, most of the existing estates have been built before the “BIM era”. Even as the the number of projects using BIM nowadays is growing, it is still not being applied to all new constructions. Technology allows to create as- built models that can be used during for multiple purposes


Uses of BIM with Existing Buildings

Facilities Management... Refurbishment... Demolition?...





Scan-to-BIM The most commonly used process to create an as-built 3D model is Scan-toBIM through 3D laser scanning. 3D laser scanning is an imaging technology in use since 1990 with millimetre accuracy the 3D laser scanning allows the creation of detailed data about a building. It has been around in the offshore sector for over 10 years. The offshore sector uses laser scanning to scan and create accurate As-Built models of oil rigs and plant facilities. However it is only in the last couple of years that the technology has been cost effective to use in the wider architectural sector. According to (LandSurveying, 2010) Surveying companies can gain many benefits using 3D laser scanning: - Decreased Field Time - Increased Visibility and Understanding - Accurate Spatial Reconstruction - Higher Precision Data - No risk to People or Animals - No effect/damage on building fabric Coparing the benfits to the traditional surveying methods it can: -Lower Overall Riskw - Reduced Rework - Decreased Project Costs - Capture Existing ConditionsHigh Resolution - Fewer Physical Site Visits

How to Scan: The scanning process can be undertaken by one individual dependant one the site and risk assessment. Using a standard tripod a 3D Laser scanner can be mounted. (e.g.Trimble TX8) To capture the digital representation of a space, a laser rotates at high speed. As the beams hit various objects their position relevant to the scanner and to other elements of site or building is recorded as a piece of digital data, known as a “point”. When several points are collected they begin to build a accurate 3D digital image picture of space. A large collection of these points are referred to a “point cloud” The more points collected, greater the accuracy of the scan. Dependant on the use of the scan may influences the amount of resolution captured.


How to Collect BIM data Scanning complete a file can be converted into a usb into a computer. Dependant on scanning hardware a software programme will need to calibrate to import to BIM authoring programmes. Having a highly accurate 3D digital representation of building more informed to design proposals, progress of works to date. Those engaged with facility/ asset management quickly have a digital picquet of existing stock to hand.

The scanning and reality capture market is undoubtedly growing fast. While there are many software firms that are innovating, the key thing holding back wider adoption is the cost of the scanners. Starting at £20,000-plus, it’s just not something that many firms would use in-house. The take-up of hand held scanners is growing, which is bringing down price and accessibility, but these still cost £3,000-£10,000 and are limited in the size of object that can be captured. Photogrammetry and video to mesh looks to be the cheapest entry point to the market and Autodesk’s Recap and Memento are enabling new possibilities from every day imaging devices. When you add drones and video into the mix, both the small and large scale are covered. The accuracy of photogrammetry is not the same as a laser scan but on the scale of a building site this could be unnecessary, while a manufactured object for fabrication would have issues.

eBIM, 2012

Scan to BIM is a work in progress and, over time, will become more automated and easier to do.

An example of this method is demonstarted in the Durham Cathedral Case Study.




The operational phase of a building is the main contributor to the building’s lifecycle cost. Estimates show that the lifecycle cost is five to seven times higher than the initial investment costs and three times that of the construction cost. As a result, there is a considerable economic and environmental need to manage both new and existing facilities in an efficient way.

Facility management (FM) encompasses multiple disciplines to ensure optimal functionality of the built environment by integrating people, place, process and technology. It covers everything from real estate and financial management to maintenance and cleaning, this variety of services highlights just how complex the FM industry is

Did you know that 20% of the total cost of a building is spent during design and construction, and 80% spent on building’s lifecycle. (YouBIM,2013)

Utilisation of BIM enabled FM has significant value-adding potential; BIM can help create and maintain facilities that are more efficient, have lower carbon emissions, cost less to run and are better, more effective and safer places to live and work. (BIMAcademy, 2015)

w14025311 According to (YouBIM, 2017) ‘we are still at the early stages of understanding the ways BIM can be used throughout a building’s life, there are at least six areas that are proving valuable.’ PREVENTIVE MAINTENANCE CASE STUDY - DURHAM CATHEDRAL A Database can be created with the information stored in BIM models about building mechanical eqipement, and can be used for maintnenance. Equipment that requires regular inspection and upkeep, particularly heating, ventilation and air conditioning equipment and life safety systems, are of particular significance. BUILDING AUTOMATION SYSTEMS Building automation systems (BAS) provide real-time monitoring and control of the sophisticated electrical and mechanical systems used in today’s buildings. Experience has shown that effective building operation is critical to achieving the potential energy savings. Although work is still in early stages, integrating BIM with BAS will provide significant benefits, particularly for technical buildings such as hospitals and laboratories. ENERGY EFFICIENCY INITIATIVES Since commercial and industrial buildings are responsible for almost 20 percent of the energy consumption in many countries, there is a mandate to analyze options to improve energy performance.


SPACE MANAGEMENT BIM models provide a useful starting point for space and occupancy management. Organizations that occupy large amounts of office space will benefit from this information. By integrating building data with human resources data, organizations can reduce vacancy and ultimately achieve major reductions in real estate expenses. BASE OF ONGOING CHANGES Managing accurate record drawings has long been a challenge for building owners and facility managers. Although BIM does not preclude the effort required to maintain accurate building data, it does provide two advantages over traditional CAD technology. LIFE CYCLE MANAGEMENT Building owners are realizing managment through BIM models are economically and ecologically better. BIM models create value in managing relevant data about current building conditions and facilitates the analysis of alternatives. Some building design professionals are embedding data on life expectancy and replacement costs in BIM models, to understant benefits of investing in materials and systems that may cost more initially but have a better payback over the life of the building




FM Preservation/Maintenance Case Study

Durham Cathedral The 900-year-old Chapter House was chosen as a pilot project to demonstrate the benefits of the Building Information Modelling (BIM) process to existing buildings, which saw the historic room turned into a 3D model. The model will aid running of a world famous, well visited, large site and the conservation and protection of an ancient monument. The project demonstrates how digital building technology can improve the efficiency in management and operation of buildings, through the transition from traditional facility management procedures to the utilisation of digital information and 3D models to deliver greater value to the institution. (BIFM, 2014)

Durham Cathedral is expensive to run and costs in excess of £3.3m annually to maintain (Durham World Heritage Site 2015). The newly hired Cathedral’s facility manager, who has previous experience of using modelling tools, encouraged the change from the current work ow of maintaining the buildings to decrease the renovation and maintenance costs and make the process more e cient and nancially sustainable. (Kassem, 2015)

w14025311 “BIM is not limited to the mainstream AEC (Architecture, Engineering and Construction) sector, but can also be implemented on historic renovation projects and the heritage conservation “ (Kaseem, 2015)

3D Model created by point clouds.

What was done? BIM Academy initially surveyed the building using the latest developments in 3D laser scanning to produce geometric models (known as point clouds) of the Chapter House. After surveying was completed, the collections of individual scans were processed to produce a single linked model of the Chapter House. The point cloud was then exported to Revit, within which BIM Academy modelled the Chapter House solely from the point cloud, before adding to the model parameters tailored to client’s needs.

Sources: (BIMFM, 2014)


Key Outcomes According to (BIMFM, 2015) The key outcomes and benefits are: - A central data-rich model available for everyday use, which allows for better informed decisions and enables a variety of facilities management and operations tasks, as well as; - Providing accurate information of the current state and layout of the building as a single reliable resource, which had previously been lacking - Traditional outputs: sections and elevations, as well as the dimensions and volumes of ceilings and walls, at no additional cost and within seconds - Condition surveys interlinked with models with the history of each element


The process of scanning the building and creating the Point Cloud took approximately 2 days. It took 15 days to create the BIModel of the Chapter House, which consisted of 3 days to understand and plan the task, 10 days for modelling and 2 days for adding parameters and creating the di erent templates, lters and walkthroughs.

- Visual walk-through around the facility - Scaffolding simulation for refurbishment planning - Scenario planning and simulation using Revit (e.g. plan an exhibition inside a room) - Ability to take accurate measurements and volumes for restoration works Field tool: utilising mobile technology to explore and update model on site

- Creation of maintenance schedules

- Production of quality visuals to communicate future proposals

Accurate Stone Surveying


Conclusion The project demonstrated that BIM can have a significant impact in supporting and developing the existing FM processes at heritage sites. This case study illustrated how a central data-rich BIM can be created and utilized in aiding the planning and execution of the restoration, and supporting the decision making of daily FM operation.

A combination of the adequate hardware, software and skillset is required to achieve the whole process from laser scanning to producing a BIModel. It can be concluded that the finished model can provide historic sites with the foundation of a new digital toolkit for understanding and managing the building moree efficiently and .or the preservation and maintenence by future generations.



BIM Retrofitting & Refurbishment BIM with renovation, retrofitting and refurbishment has a significant less ammount of research and implementa towards the other FM uses of BIM (SmartMarket Report, 2010)

The most interesting of all the topics covered is BIM and its use in the refurbishment and retrofit markets. When the value of the works at hand are generally less than it might cost to produce useful BIM models, one has to ask the question, why use BIM at all?

Due to the small ammount of projects on BIM for refurbishments,there is very limited accessable data. Most of the data is supported through the use of case studies of projects. However BIM+ has conducted an interview with Allan Hunt, a chartered building surveyor and director at architect and building consultancy AHR, on the challenges of implementing BIM on small-scale refurbishment projects at the University of Sheffield.

Using a survey tool such as Refurbify, whole property surveys have been captured either during one visit or smaller surveys completed during ongoing maintenance visits. The difference with these surveys compared to others is that they have the end goal in mind. The costs, the products, the labour and the time required to perform any chosen measures on properties are being surveyed. Once this data is captured, an IFC model of each property is immediately available on the Refurbify cloud. This model can be instantly queried to provide estimated schedule of costs and durations for any work measures that are of interest. Contractors can be sent a link to IFC models, along with associated tagged information such as photos and videos, specified products and labour skills. Costs and products can be agreed and added directly to the system so that the BIM data is updated accordingly. (Source: PBCtoday,2013)




Souce: (BIMplus, 2014) According to BIM+ an interview was taken place with a Allan Hunt, who had used BIM as a means of refrubishing a small lecture theatre Doesn’t constructing a 3D BIM model involve a lot of input for a small refurb project? “Not if you only build section of the model related to the area you are refurbishing. And if you are doing subsequent projects on the same building it is not long before you have a full model of the asset you can use in the future. Then it is no longer a case of having to build the model again, it just gets tagged into future workflows, which means clients don’t have to pay for that design work again and so they get better value out of their programmes.”


Souce: Refurb BIM Lecture Theatre (BIMplus, 2014

With a refurbishment project, there can potentially be many unknown factors waiting to reveal themselves. Refurbishments are inherently risky as there is always a surprise waiting to cause delay or simply pile on the costs. BIM used properly can be seen as a risk mitigation tool, and while the emphasis is still on multidisciplinary collaboration, it is apparent that the application of BIM is slightly nuanced from a ‘traditional’ BIM project. Managing and sharing the risk by setting the right contractual framework is also critical. Recent research has shown that the use of NEC contracts by clients is becoming the mainstay of their procurement and contracting strategy for refurbishments.



BIM Refurbishment Case Study

Guild Hall Yard, Lon BIMBox Consulting were invited to work with the team at Willmott Dixon Interiors to develop a data rich asset information model and supporting COBie schemas with digital O&M information aligned with PAS1192-2 and delivered through a common data environment.

The Client requested a BIM model after site works had finished. However, to implement the BIM process after the project has been completed, WDI had to retro create documents that would normally be crucial for BIM implementation from the onset,

Willmott Dixon Interiors (WDI) was appointed by the City of London to carry out full refurbishment works to the first to fourth floors and ground floor reception area of this building. The art gallery, which was completed in 1999, was to be the first pilot of BIM Level 2.

The Employers Information Requirements, normally produced by the Client, and a BIM execution Plan, normally produced by WDI, while also having to reengage with the project team.


ndon The project called for the interpretation of a comprehensive set of traditional construction drawings and specifications followed by the creation of Architectural, MEP, Interior & FFE models. These models were clash detected and federated to produce the final COBie output. Using BIM in the 20-week, £3m refurbishment of Guildhall Yard East enabled Wilmott Dixon Interiors to reduce risk and the OpEx costs for the Client. .

Conclusion Given the limited infro on implementing BIM soley for the use of refurbishment projects. From the data presented from Allan Hunt and the case study of guild hall. We are shown that the majority benfit of using bim for refurb projects is for larger scale projects due to the cost of the survey compared to the overall cost over traditional surveys. As well as the facilities managment benefits for the following life cycle. However Allan Hunt explains that BIM for refurbs can be used for smaller scale projects. ‘If you only build section of the model related to the area you are refurbishing’.The asset model to use again the near future for workflows, meaaning reducution in costs.




BIM Demolition / Deconstruction The increasing global urbanisation has resulted in high volume of Construction, Demolition and Excavation Waste (CDEW) from which demolition waste contributes up to 31.8 million metric tonnes yearly in the UK alone (WRAP, 2009). With so many demolitions taking place annually, its environmental and economic impacts cannot be ignored because building materials become unrecoverable and eventually sent to landfills.

According to (Eadie et al. 2013), a distinguishing feature that makes BIM applicable to all work stages is the accumulation of building lifecycle information. As such, information on building requirements, planning, design, construction, operations and even information on recycling materials can be accumulated and accessed at the end of life of buildings.

Case Study Wolverhampton Bus Station

“A BIM model helps us understand the impact of removing structural elements, what kind of machinery the structure will support, how much articulation our demolition equipment will require, how our work will interface with other trades and detect clashes.�



Can BIM be used for conventional demolition projects? “The Wolverhampton Bus Depot demolition process consisted of Coleman using a 3D scanner to create a digital point cloud, from which a BIM model was created. The model was then used to plan demolition sequencing. It has a steel portal frame, and the model was created from scan to BIM. This allowed Coleman to determine section sizes, and plan the demolition sequence (crucial when there are big machines snipping through the trusses, and removing the wrong section too early might affect the structure’s stability). How does BIM work with machinery use? “The BIM model tells us what machinery loads the structure can carry and any constraints on operations. At New Street, we calculated we could use a 25-tonne excavator using significant temporary works, which would make the job far more efficient than a 2.5-tonne Brokk robot which would typically have been used. So we developed a bespoke excavator with JCB using 3D modelling, and imported this into the client’s BIM model. It is remote controlled, so the operator can be outside the cab when guiding the attachment, with a full 360-degree view.”

INTERVIEW: MARK COLEMAN BIM+ talks to Mark Coleman, managing director of The Coleman Group and deputy chairman of the CIOB’s Birmingham Hub. This is leading to big time savings. If an engineer measured the depot using a MEWP, it would of take seven days where as the scan took only a day. The excavator improved productivity immensely. It was also safer – there is an infrared field which cuts off the power if the machine passes a ‘virtual safety barrier’. It has a modular design, making delivery easier and allowing it to be assembled on site and moved from floor to floor as work progressed. We are now using the machine on other specialist projects.

Future... Future of Scan to BIM:

Futue of BIM & Existing Buildings:

“Laser scanning has come along way in recent years, with advancements in technology scanning equipment has become far more efficient. This has made laser scanning (which is often seen as expensive.. pushing people to use more traditional techniques which offer added value) much more affordable, quicker and therefore widely used. As technology develops further over the next 5-10 years, mobile scanning will become more accurate, (Zeb-Revo, Pegasus:Packpack) and will replace static scanners (P20, Z&F 5010C), as again, they will become more efficient solutions.”

“Laser scanning is a great platform to allow as-built geometry to be created for existing assets. The only drawback is that, once you have the scan, there is no automated process currently which can create geometry. Irregular and complex buildings are difficult to model in some software packages. So you have to choose wisely depending on the asset / structure. That geometry can then be populated with existing information such as condition, material etc. This feeds directly to the Architects and Engineers who use the models to aid their design work. Some Architectural practices use existing 2D information to create 3D models, which is fine in some cases. However it is far more accurate to not rely on historical information and to commission a laser scan. BIM for existing buildings has a strong future aided by laser scanning technology and the Government mandate. As soon as the industry realise the long-term value in BIM, there will be no hesitation to invest in the upfront costs that the implementation incurs.“

Shelby Green BSc (hons) Scan2BIM Department Manager

To gain reliable information on the futue of scanning to BIM and BIM with existing buildings. An email request of this information was sent to Scan2BIM depertment manager Shelby Green. Above are her thoughts on the matter.


Future of BIM: The transition to BIM Level 2 and hopefully soon enough to Level 3 will have some important benefits for the construction industry. In short, we could sum up some of them below: The ability to share information faster and easier can offer a significant productivity boost. Collaborative working can decrease the required time for incorporating and editing new information. Increased productivity means also lower cost and by extension higher efficiency in terms of project planning. This will help twards to Industrial vision for 2025. BIM will offer remarkable help in handling vast amounts of data. The more effective managing of big data will change the way many of the professionals within construction (eg. contractors, engineers etc.) are working. It’s expected that a higher demand for data will emerge, as well.


Furure of Demolition with BIM: BIM+ talks to Mark Coleman, managing director of The Coleman Group and deputy chairman of the CIOB’s Birmingham Hub, about how BIM can make a difference on demolition projects. Are we moving towards a world where demolition machinery will be mostly remote controlled or even automated? (BIM+, 2017) “We are certainly heading in that direction. Brokk demolition robots are remote controlled, and they can be programmed to tackle work in a certain sequence, so that key structural elements are not removed too early. The next step is to link that to BIM. The day may come when we tag structural elements in the BIM model which are then automatically dismantled by machinery, with the operator controlling remotely as if it was a video game.” Source: (Coleman, 2017)
