USGIF GotGeoint Blog USGIF promotes geospatial intelligence tradecraft and a stronger community of interest between government, industry, academia, professional organizations and individuals focused on the development and application of geospatial intelligence to address national security objectives.
The UK Government as part of its building information modeling (BIM) initiative has said repeatedly that it expects the big payoff of a digital model, estimated at more than 40% savings, will be during operations and maintenance, typically representing 80% of the total cost of a facility. Companies such as BAM who do Design, Build, Finance and Maintain (DBFM) projects report significant benefits from full lifecycle BIM + geospatial. But there is little if any quantitative evidence supporting this conjecture. I have asked people from Finland familiar with the very early BIM developments in that country if there were studies of the benefits of BIM for operations and maintenance, but apparently the BIM focus there has been entirely on design and build.
Crossrail with a budget of £14.8 billion is the biggest engineering project in Europe. It involves 42 km of tunnels beneath one of the most densely populated parts of Europe. It has wider tunnels and its 40 stations have longer station platforms than the Tube has. Crossrail trains are expected to start running next year and the full network should be open by 2019.
But the most interesting aspect of the Crossrail project is a 3D digital model with associated asset data that has not only been used during design and construction, but is intended to be used for operations and maintenance. Crossrail appears to be the first major project that may be able to provide support for the conjecture that the biggest benefits of BIM are for operations and maintenance.
The Crossrail model is comprised of spatial and non-spatial data with links between the two. The spatial data is made up of more than 250,000 3D BIM models as well as as-builts, together comprising a few terabytes. As construction of each facility is completed as-builts are collected by point-cloud survey using laser scanners. The point clouds captured in the survey are compared to the design and divergences that need resolving are recorded for fixing. The detailed asset data and documentation add an additional 5 terabytes. This represents one of the World's largest BIM model. A critical aspect of the spatial database is that all assets are geolocated so that workers can query a particular location of London on a map and then navigate to the Crossrail assets there.
The model is intended to become a crucial tool for monitoring, operating and maintaining Crossrail’s systems once the railway is running. Sensors monitor various aspects of the railway's operation and remote-controlled devices can change operating parameters from a central control room or from a handheld device. Managers can view this information within the 3D model and can zoom in on an area which needs attention. Crossrail is testing low-power wireless smart sensors called Utterberries that can monitor strain, temperature, humidity, acceleration, and other aspects of a facility. Utterberries weigh 15 grams and are smart - they have an ARM processor on-board and can operate for more than a year on one charge. One of the coolest capabilities of the digital infrastrucure is an augmented-reality interface which allows workers to hold an iPad up to a wall or floor and see a view of the infrastructure (electricity, water, and communications) under the floor or behind the wall.
The latest USGS earthquake risk maps for the first time show the probability of earthquakes next year in the central and eastern U.S. The new USGS hazard model estimates where, how often and how strongly earthquakes may could occur in the central and eastern United States during calendar year 2016. Also for the first time they include human-induced in addition to natural earthquake risk. Induced earthquakes are linked to human activities the most important of which is wastewater disposal from oil and gas production operations (wastewater from fracking).
According to USGS the central U.S. has experienced a dramatic increase in tremors over the past six years.
Average number of earthquakes of magnitude 3 or greater per year in central U.S. 1973-2008 24 2009-2015 318 2015 1010 2016 (to Mar 15) 226
The largest recent earthquake in the region, a magnitude 5.6 tremor, occured near Prague, Oklahoma near several active injection wells.
By way of history the biggest earthquake in the U.S. east of the Rockies was the 1811/1812 New Madrid earthquakes of estimated magnitude 7.6 -8.0. This occurred near the Mississippi just south of the tip of Illinois where Missouri, Arkansas, Tennessee, and Kentucky come together. Significant risk of major seismic activity in this area continues.
Registration is Now Open - GITA Pacific NW Chapter 2016 Conference
I have been attending and speaking at GITA events for many years. One of the best events is the geospatial, utility and infrastructure event organized by The GITA Pacific Northwest Chapter, always in an interesting location in the Pacific North West and British Columbia.
This year Peter Batty and I will keynote as part of an agenda that includes presentations by regional experts. The reason I like regional events is that there are often better opportunities for one-on-one networking with speakers and other folks in the geospatial, utility and other sectors than at the large national events.
This year's event takes place at the Boeing Future of Flight Aviation Center near Seattle. You can register here.
When: April 18-19, 2016 Where: Future of Flight Aviation Center 8415 Paine Field Boulevard Mukilteo, Washington 98275 United States
The GITA Pacific Northwest Chapter Conference returns to the Future of Flight Aviation Center,
The Netherlands has created a new BIM Loket (BIM Gateway). It is intended to be a national portal for information about and and management of open BIM standards in the Netherlands. It is to both provide a central information centre for open BIM standards including related geospatial standards and to stimulate their use.
The most important reason for building a BIM Gateway for all stakeholders is to reduce maintenance costs by bringing together the open BIM standards into one coherent system. This will ensure that the standards can be used more effectively and with greater efficiency as well as promoting their widespread use.
The Dutch Building Information Council (BIR) has been encouraging BIM for a long time. I have blogged about it previously. It will continue to focus improving the quality and competitiveness of the Dutch construction industry through initiatives such as BIM. The BIM Loket's focus will be on open standards for BIM. One of my takeways from the recent RICS BIM conference in London was that there is a desperate need for standards, especially to classify the huge amount of date in addition to the 3D model that accumulates during a construction project. Much of this would be useful to the FM folks who are responsible for operating and maintaining the building after construction.
At a Geospatial World Forum in Amsterdam several years ago, Jantien Stoter of the Delft Univeristy of Technology and an advisor to Geonovum, described work on the Dutch 3D standard which aimed at integrating CityGML and the Dutch IMGeo standard. This inclcuded an attempt GeoBIM which was to be a CityGML Application Domain Extension (ADE) intended to extend CityGML to include detailed, semantic information about the inside of buildings (IFC). Finding some way of integrating of BuildingSmart's IFC BIM standard and geospatial standards like CityGML remains a major challenge for the international construction industry.
As a practical example, I blogged previously about a firm Royal BAM Group nv / BAM Infraconsult that relies on integrated BIM and GIS because many of its projects require full life-cycle BIM. At the first GeoBIM conference in Amsterdam, Jothijs van Gaalen gave some real world examples of Design, Build, Finance and Maintain (DBFM) highway construction that included GIS+BIM integration. BAM's motivation for investing in BIM+GIS are market developments especially more complex construction assignments and an increasing demand from customers for service provision throughout the entire life cycle of a project. The other major drivers are internal business needs especially being able to control safety, quality, costs, planning, and sustainability through the lifetime of a project.
As another example, ARCADIS Netherlands has been involved in projects that integrate geospatial into the design process. On the HOV Nijmegen project it was found that integrating geospatial and engineering design in a single database resulted in a single copy of each data element which supported multiple use. It simplified communication and increased the quality of the final design. It also enabled automated analysis of the consequences of design choices with the result that the planning cycle was shorter. Based on their experience with these projects, Bram Mommers and his colleagues concluded that there are several barriers to the integration of civll engineering and geospatial; Semantics, different terms used for the me things by geospatial analysts and civil engineers and designers, different topology, geospatial uses point, lines, and polygons, CAD/BIM uses splines, nurbs, and other parametric curves and treats polygons in a different way from geospatial topology, and features which are fundamental objects in geospatial vs engineering objects with location as an attribute, and data formats, geospatial data is stored in shape files, GML, and CityCML; CAD/BIM uses DWG, DGN, RVT, and IFC.
As the UK AGI has pointed out in a recent Foresight Report integrated BIM and geospatial technology will be fundamental for BIM Level 3.
The BIM Loket is intended to be a one stop shop for BIM-related standards including geospatial, whether maintained in Holland or internationally. It is intended to involve all the stakeholders, industry, academia, and government organizations. It is considered urgent because standards are essential for the digitization of the Dutch building industry and it is essential if Dutch construction firms like Royal BAM and Arcadis Netherlands are going to remain internationally competitive. The BIM Loket plans to compile a knowledge platform based on a coherent palette of Dutch open BIM standards for industry-standard BIM products.
Thanks to Rob van de Velde for pointing me to this.
The Open Geospatial Consortium (OGC) standards process is quite nimble compared to other standards development processes, but it still involves multiple steps and the overhead of the formal process discourages developers from participating. For reference the Request for Comment(RFC) procedure is the most common way for a candidate standard to enter into the OGC standards approval process. A very good guide has been prepared for submitting an RFC to the OGC and then manoeuvring the candidate standard to final formal adoption.
The OGC has been moving in the direction of a simpler developer-friendly process for standards development. An important motivation has been input from the open source community. Last year Chris Holmes, who was unhappy with the progress in the development of a standard called GeoPackage, decided to join the GeoPackage Standards Working Group (SWG), to learn about how the OGC standards process actually worked so as to be able to offer some suggestions for improvement from an open source software perspective. This was important for the OGC perspective for two reasons. First of all, open source geospatial is an important and growing segment of the geospatial software community, and secondly "open source loves standards" so that historically the first implementations of a standard and the first adopters have often come from the open source community.
It turned out that OGC staff and the members of the SWG were open to new ways of working and the SWG achieved an OGC first by putting the GeoPackage specification out on GitHub, to make it accessible to the open source community. The traditional OGC way is wikis and Word docs. For folks without GitHub experience the SWG prepared tips on how to contribute to the GeoPackage specification without having to learn git. For the OGC putting the specification on GitHub was an experiment, which turned out positively. The resulting standard benefitted from the direct involvement of open source geospatial developers in the OGC standards specification processes. The result was an alternative standards process that focused on early implementations of the standard. The standards process itself was improved by reducing the overhead in the formal OGC process.
The OGC is now taken this one step further and is working on a "standards incubator". The goal is to make OGC processes even more nimble and responsive to rapidly evolving technology. The standards incubator is intended to provide a setting for members to build and evaluate innovative draft standards in a process that mimics the usual OGC standards development process, but does not result in an official OGC standard. It is intended to reduce overhead to zero in order to provide a minimalist formal process.
In a recent presentation announcing Tesla Energy Elon Musk estimated that the total surface area needed to generate enough power to get the U.S. completely off fossil fuel power generation is less than 1/4 of the Texas panhandle.
Solar PV has reached or is approaching parity with fossil fuel energy sources in much of the U.S. and distributed power generation, primarily rooftop solar PV, is disrupting the traditional electric utility business model. The fundamental problem is that as customers install solar PV on their rooftops or find alternative sources of power and even leave the grid, the utility's revenue, which is derived from selling electricity, declines. This in turn drives up rates for the utility's other customers which motivates them to also defect. Put another way the electric power market, which used to be based on a regulated monopoly provider, is giving way to a competitive market where the consumer has a choice. She can generate her own power or buy it from alternative sources such as Solar City. As battery costs drop, customers increasingly have the option of leaving the grid and participating in their own or a community microgrid.
I've blogged about several alternative solutions that utilities and regulators are proposing to meet the challenge of distributed renewable energy. The New York Public Utility Commission is moving the New York state utility industry toward a radical refinition of the utility business model. In the future in New York state the utility industry may be comprised of distributed system platform (DSP) providers, basically providing the grid but not directly selling energy. There will be an energy market with many energy providers including bulk power generators and many distributed energy generators - you and me with rooftop solar panels. Sacramento Municipal Utilities District ( SMUD) is moving from being a traditional centralized utility to a distributed utility providing localized grid services. In other words SMUD is getting out of the business of selling electricity and into the business of selling grid services. In Maryland the Energy Future Coalition (EFC) prepared recommendations for the Maryland smart grid among which the key recommendation was a new utility business model that would decouple utility revenue from selling electric power. Recently it was predicted that by 2020, the largest energy company in the world (by market cap) will not own any network (grid) or generation assets. It will just manage information about energy sources and consumers similar to Uber and Airbnb in their markets.
Some utilities like Hawaii's power utilities are embracing distributed renewable energy and adapting their business model. The Salt River Project has introduced a rate structure designed to charge solar PV customers for using the utility's grid infrastructure, but which incentivizes them through "time of generation" pricing to generate power at peak times when demand is high. Other utilities see rooftop solar PV as a threat to their revenue base and are penalizing customers who install rooftop solar PV, either by a fixed infrastructure charge or by reducing the rate the utility pays for customer-generated power.
I just came across another approach to address the problem of customers generating their own power leading to declining revenues for the utility. One utility's strategy is to not only lower the rates paid for customer-generated power but to make them (at least large customers) pay a fee (penalty) to leave the grid. There is an open question about whether this is even legal and it is being challenged in the courts.
NV Energy, which is owned by Berkshire Hathaway, is the power utility for Las Vegas. The casinos, to reduce their power costs which are significant as you might expect, have started finding alternative sources of power. For example, the Mandalay Bay is installing the largest rooftop solar PV array in the U.S. on top of its convention center (6.4-MW dc system with 21,324 solar modules expected to provide 20% of the resort’s power demand.). Others are looking to buy power on the open market. With the available alternatives the casinos and resorts are planning to leave the grid and Nevada Energy's monopoly. They want to do this because it saves them money.
The resorts and casinos consume about 7% of NV Energy's power. If they leave the grid, it will create a significant hole in NV Energy's revenue. NV Energy is an investor-owned utility and makes a profit which returns value to its investors. NV Energy's solution (with the acquiescence of the state power regulators): charge customers a fee for leaving the grid. According to the source, it will cost the casinos and resorts a fee (penalty) of $126.5 million to leave the grid. The penalty is to compensate NV Energy for investments it made to generate power for the casinos and to prevent raising rates for NV Energy's remaining customers.
The casinos and resorts are not the only customers of NV Energy to face a penalty for leaving the grid. A data storage company called Switch had the same problem last year when it decided to use renewable power to power its data center. It uses 3% of NV Energy's power and the company was told it had to pay $27 million to NV Energy to leave the monopoly's grid. Reportedly Switch and NV Energy came to an agreement where Switch is paying NV Energy to build a new solar farm in North Las Vegas. This looks like a policy whereby NV Energy pressures its big customers to remain with the monopoly and pay for its sustainability initiatives through the threat of a substantial penalty for leaving the grid.
Thanks to Derrick Oswald for pointing me to the NV Energy story.
The world is changing. Microsoft has been doing things in the open source world for some time, but this last week it has gotten wild.
Microsoft has just kicked off launch activities for SQL Server 2016 with general availability later this year. Spatial data has been supported in SQL Server since 2012. According to a Microsoft blog post this is the most significant release of SQL Server ever. It includes some very cool technology: in-memory database support with dramatic performance increases and advanced analytics based on R that enables customers to do real-time predictive analytics on both operational and analytic data among other things. Microsoft introduced Polybase, a SQL Server connector to Hadoop in 2015. Microsoft has now incorporated that functionality into on-premises SQL Server 2016.
That's all pretty cool, but the biggest surprise is that Microsoft has announced plans to bring SQL Server to Linux. The core relational database capabilities are being previewed right now. SQL Server 2016 will be available on Linux in mid-2017.
Microsoft has just released the source code to an open-source operating system, based on Debian GNU/Linux, that runs on network switches. The software is called SONiC (Software for Open Networking in the Cloud). SONiC builds upon Microsoft's Linux-based Azure Cloud Switch (ACS) operating system.
What is BIM Level 2 and how do I know I am compliant ?
What if you are a small company with no more experience with BIM than discovering what the acronym stands for ? It turns out that one of the biggest challenges, especially for smaller firms, is just what does BIM Level 2 means in practice. What do I have to do to be compliant ?
At RICS BIM 2016 there was a sequence of presentations by a group of mostly quantity surveyors (people who do quantity takeoff), all BIM novices, who came together to try to understand and share openly what BIM Level 2 means practically. This project brought together seven knowledge transfer initiatives funded by InnovateUK. They called it KT4BIM (which you can find on Twitter at #KT4BIM and on LinkedIn). The objective of the project is to answer the questions
how do we do BIM Level 2 ?
how do we demonstrate compliance ?
The target audience is BIM novices in both the residential and commercial sectors of the construction industry. KT4BIM intends to share all the material used and developed as part of this project with the rest of the industry.
They setup a mock project so that they can work through five stages, from stage 0 through 4, of an actual construction project. The project started with Stage 0 & 1 of the RIBA Plan of Work, the definitive UK model for the building design and construction process. From there the plan is to work through Stages 2 to 4 to create a design and various outputs to test the Level 2 process. The roles included in the mock construction project are the Client (owner), Information Manager, Architect, Structural Engineer, HVAC, Fit Out Contractor, Cladding Contractor, and Virtual & Augment Reality, with professional representatives from industry and academia responsible for each role. BIM4SME is playing the role of client.
Initially it was expected that Stages 0 and 1 would require two and a half months. But Stage 0 has taken much longer than expected because right at the start they encountered a major challenge in the form of many very complex standards, which at that time were to be found on different web sites.
Question 1: What are the BIM Level 2 standards and which are required ?
There are a many BIM Level 2-related standards, BS 2007, PAS 1192-2, PAS1192-3, PAS1192-4, PAS1192-5, Government Soft Landings, ... and on several different sites, BIM Task Group website, B1M, and others.
The good news is that there is now a single web site (BIMLevel2.org) where all the documents can be accessed. But it is quite a list and it is hard to know where to start.
Question 2: With so many documents where do you start ?
There are several alternatives. PAS1192-2 is the most read, but PAS1192-3 and PAS1192-5 provide a broader perspective on the whole life cycle process. The KT4BIM team recommends starting with PAS1192-5. If you are an employer (client), it is recommended that you begin with the Built Asset Security Strategy (BASS) and Organizational Information Requirements (OIR) sections. If you are a consultant, then you should begin with the BIM Execution Plan (BEP) section.
Presumably, since BIM Level 2 is mandated by the UK Government for public projects, a company could risk legal action for noncompliance (although one speaker mentioned that there is no legal definition of BIM Level 2 compliance). The question KT4BIM intends to answer is
Question 3: How do we as contractors know when we are BIM Level 2 compliant ?
KT4BIM came up with the concept of a Success Matrix, an Excel spreadsheet that signals degree of compliance. The tool is intended to be accessible to the entire team from client through to contractors and it is designed to provide an interactive learning experience for all project managers. The Information Manager can utilize the tool to effectively police the project. It is designed so that a client (owner) with a low level of training can use the tool to make sure they are getting a fully compliant BIM maturity level 2 project. It is also expected that the Government Soft Landings Champion (see Government Soft Landings) will also benefit from the tool.
A very good and readable (for BIM novices) overview of Stage 0 of the KT4BIM project can be found here. It is intended that the project will continue through to Stage 4 and I expect that many, especially folks for whom BIM is new, will be following the progress of KT4BIM with a lot of interest.
At this year's RICS BIM conference the elephant in the room was April 4th 2016, the deadline for all public construction projects to be BIM Level 2 compliant. This is the culmination of a five year process starting in 2011 focussed on developing a set of documents defining BIM Level 2 and providing best practices for achieving compliance.
This year's conference suggests that for many in the industry they are now wrestling with implementation issues and are reporting a shortage of BIM skills. They are finding that BIM is really about data and are realizing that data management and analytics are essential to handling and interpreting the huge volume of data that is being generated. A shortage of data scientists to help them to do this has become an acute problem.
Transforming the UK Construction Industry in Five Years
The government's focus from the beginning has been on full life cycle BIM. Back in 2010/2011, the Government's BIM roadmap was perceived to be very aggressive, mandating BIM Level 2 compliance for all national government projects after just five years. In the UK public projects comprise about 50% of the construction industry so this amounted to radically transforming the UK construction industry in half a decade. Put another way the construction industry had to move from thinking analog to thinking digital in just five years.
The utility industry has been going through a similar transition in moving to what is called a smart grid and distributed generation. Some think that this process will take 20 years. But new technology and a younger generation steeped in digital is stepping in to make this happen much sooner than that. Energy is going digital more rapidly than expected. I think it likely that something similar will happen in the construction industry because digital enables all sorts of efficiencies that we often cannot even imagine. Uber and Airbnb are classic examples. Both are the largest or second largest companies in their respective industries. Gartner has forecasted a similar type of company will emerge for managing energy flows in the electric power industry by 2020.
For 2012 the Government's strategy focussed on discovery through pilot projects, notably the Ministry of Justice Cookham Wood project, a £20 mllion project where it is estimated that BIM saved hundreds of thousands of pounds in CAPEX costs.
At the 2013 conference David Philp,Head of BIM Implementation, Cabinet Office, UK Government, announced PAS 1192-2 a key document supporting the Construction BIM Strategy to achieve Level 2 compliance. It specified requirements for achieving BIM Level 2, sets set out the framework for collaborative working on BIM enabled projects and provided specific guidance for the information management requirements associated with projects delivered using BIM. David Philp made it clear that although the initial focus is on the design/build part of the lifecycle with the goal of saving 20% of Capex and reducing the 30% waste in most construction projects, the "largest prize for BIM lies in the operational stages of the project life-cycle".
At the 2014 conference Peter Hansford, Government Chief Construction Advisor, made a link between the overwhelming interest in BIM as represented by the sold-out RICS BIM conference and the industry’s enhanced interest and appetite for BIM. He saw a shift in emphasis from asking ‘’should we do BIM?’’ to ‘’how do we do BIM?’’ This was happengin inspite of the fact that as, Rich Saxon, the UK Government's BIM Ambassador for Growth, pointed out In a panel discussion on the future of BIM that some aspects of BIM Level 2 were still incomplete.
Deborah Rowland, Head of Facilities Management, Government Property Unit, Cabinet Office in the UK Government outlined the Government's motivation and plans for a program to improve the post construction handover and operation of newly constructed buildings. She described the Government Soft Landings (GSL) program which was intended to rectify this and was designed to put in place a legal, contractual, and technical framework (based on the BSRIA Soft Landings Framework) incorporating building information modeling (BIM) to fix the problem by ensuring continuity thoughout the buiiding lifecycle from inception, though design, construction, commissioning, training and handover through to operations and maintenance for 1-3 years after handover.
At the 2015 conference seven key BIM Level 2 documents (PAS 1192:2, PAS 1192:3, BS 1192-4, CIC BIM Protocol, Classification (Uniclass), Digital Plan of Works / Levels of Detail (LoD), Government Soft Landings) which collectively represented the current repository of BIM best practices were announced. Every speaker at the conference referenced these documents.
Seven major government projects using BIM, worth about £ 10 billion, have maintained records of the savings they have seen from using BIM. The measured benefits of BIM and factors associated with BIM range between15-20 %. By 2014 the government estimated that it had achieved savings of £ 1.4 billion through BIM and related improvements in the 2013/2014 fiscal year. But with full lifecyle BIM, the government saw an upside potential of 40%+ with the biggest benefits being realized in the operations phase of the building lifecycle.
This year it was announced that Government statistics show that in 2015 Her Majesty's Government saved GBP 3 billion on these demonstration projects as a result of gains in construction productivity related to BIM.
Full Life Cycle BIM
But BIM Level 3 is where the gold is. Level 3 will enable the interconnected digital design of different elements in a built environment and will extend BIM into the operation of assets over their lifetime. It will support the accelerated delivery of smart cities, services and grids. As the AGI has pointed out in a recent Foresight Report integrated BIM and geospatial technology will be fundamental for BIM Level 3.
Is the UK construction industry ready for April 14 2016 ?
An industry survey in the UK in 2013 reported that 54% of respondents said that they were using BIM on projects. Most of those not yet using BIM said that they would be within one to two years. 70 % of the respondents reporting using BIM said that BIM has given them a competitive advantage. But this year's conference suggests that most in the industry are doing BIM although for some it is not really clear what BIM Level 2 is and how one demonstrates compliance.
Data and People
This year's RICS BIM conference was quite different from previous conferences. The focus was heavily on implementation, not on progress in completing specifications or developing and working with 3D models as in previous RICS BIM conferences.
The event was led off by a panel discussion that set the tone for the rest of the conference - the focus was on data and people rather than 3D BIM models. The industry people on the panel were patently up to their elbows in real world BIM projects including data, the analytics to make sense of it, and the shortage of the required skills (data scientists and people with BIM skills).
Alex Jones, Interserve, said that within the construction industry there is now a focus on data and how data is used downstream. He said that clients (owners) are now aware of BIM and that both private and public procurements are asking for BIM. But he qualified this - they are not so much asking for BIM (as in 3D models) as asking for data that can be used downstream. David Throssel, Skanska, added that deliverables now means data.
In the context of data, Simon Rawlinson, Arcadis UK, gave an example of utilities where smart devices and automated capture has resulted in a database of asset conditions, and which also includes geospatial data for geolocating those assets. This information allows utilities to move forward to condition-based maintenance where prioritizing maintenance and replacement depends on asset condition not the calendar. Real-time monitoring is being adopted by virtually all industries. For example, devices are being implanted in structures such as bridges to monitor distortions. He added that the leadership has not yet recognized that sensors and analytics enable a major change that will revolutionize asset maintenance.
Also the new digital economy is disintermediating certain skills. For example, digitalized construction requires fewer layers. Simon cited a KPMG study of disintermediation by technology. As an example, he mentioned data such as that collected by utilities from smart devices that allows owners/clients/utilities to do condition-based maintenance, which can lower field staff requirements significantly.
In the construction industry as a whole one of the major issues that emerged is a shortage of BIM related skills.Simon emphasized that now that we have lots of data, what we need urgently are data scientists to help make sense of it. He identified this as a major problem because in his experience data scientists are as rare as “hens teeth”.
David Hancock, UK Government Construction, said that construction industry still thinks analog. Nowadays we can all produce data, but analyzing it is the challenge. We need people who can analyze to produce actionable items. He also identified BIM skills shortage as a major problem, and repeated that data scientists people are “as rare as hens' teeth. He suggested that one solution is upskilling – training existing construction/bldg maintenance/utility folks in BIM and data science. Another may be raiding the U.S. baseball industry where teams such as the Oakland Atheletics starting using analytics several years ago. "Moneyball" analytics has been recommended as a strategy for the utility sector in the U.S.
In the question period a speaker argued that the 3D BIM model has been "massively overplayed". BIM is really about data and collaboration, not about 3D. To maximize the benefits of BIM clients (owners) have to be clear about what the model, and much more importantly the data associated with the model, are going to be used for. For example, if for facilities management (FM) then clients (owners) have to be specific about what data is required for maintaining and operating the building as part of defining deliverables.
