PRESIDENT’S MESSAGE We are pleased to present the 13th Issue of the USIBD’s Cornerstone Report (CSR). This issue introduces a new topic of Data Distribution to the Cornerstone series. In recent years, the adoption and advancement of Building Documentation technology has greatly increased the amount of data available on a project. The ability to collect more information creates both opportunities and challenges for service providers, vendors, and end users alike. This issue explores the industry trends related to managing and distributing data and identifies some key pain points shared by industry stakeholders. This survey provides an in-depth look at reality capture data management and its impact on process and deliverables. Respondents indicate several pain points when collecting and processing large data sets revealing the need for purpose-built storage and processing solutions. It is clear that how data is managed, stored, and distributed can have a substantial impact on costs, timing, and overall success of reality capture implementation. I would like to extend our gratitude to all the CSR survey participants. The benefits of shared knowledge and collective experience are a rare consistency in our ever-evolving industry. It is your continued support and willingness to share knowledge and experiences that allows us to continue to bring value to the building documentation community and stakeholders through this survey and report. We hope you will contribute to future Cornerstone Report surveys. We encourage you to share this report with your network and invite your friends and colleagues to participate in our surveys. On behalf of the USIBD’s Board of Directors and Technology Committee, we hope you enjoy this issue of the USIBD Cornerstone Report. Sincerely, John M. Russo, AIA

President, USIBD

Introduction This survey grew out of many questions at the last USIBD symposium (SPAR 2019) about how people were storing and distributing reality capture data within the AEC industry. With 149 respondents, this is one of our top three surveys in total number of participants. We would always like more, but this gives us a good number to draw conclusions from and look for trends in sub-sections of the demographics. Thank you to all who took the time to respond and contribute to our efforts! This is our first survey on data sharing and delivery, so we have no prior data to compare against. However, we are looking forward to iterating on this survey in a few years, particularly post-pandemic! Readers should bear in mind that this survey’s responses were pre-pandemic. Obviously, the dramatic changes in acceptance of work-from-home and other remote working arrangements during the pandemic would result in different responses to a survey of this nature. So, please put yourselves in a pre-pandemic mindset when looking at the results below.

Company Demographics Each of our surveys experience varying participating from the industries USIBD supports. While our last few surveys heavily favored general contractors, this survey was more representative of our membership overall, with our largest respondent group being reality capture capable service providers. Interestingly, we had enough people outside of our typical contributors for “Other” to be the third largest group!

Like our last few surveys, company size trends towards the extremes with firms under 100 people making up over 50% of the respondents, and firms over 1000 making up over 25%. There are noteworthy trends in company size amongst the various types of firms. These more detailed results can be found in the full report available to USIBD members, member firms, and sponsors.

Connectivity Demographics The core challenge that makes the storage and distribution of reality capture data so difficult is the size of the data itself. Complaints about distributing model files have largely been addressed by the steady improvements in network and internet bandwidth. However, these increases have not yet caught up to the terabytes of information that can easily be created on even medium sized reality capture jobs. So, we also asked a few questions about each company’s connectivity internally and externally. Unsurprisingly, most firms have moved to gigabit LAN, though a surprisingly large number of firms are still on very slower internet connections with over 60% still on Mb service.

Now, to correlate this to something concrete, let’s remember that connection speeds are typically provided in bits per second instead of bytes per second. Why do I care you ask? Well, because there are 8 bits in a byte. So, if you have a file that is one megabyte in size it is composed of 1 million bytes, but 8 million bits. Bits are what has to get transferred, which is why connectivity is described in Mb (with a little b) while file size is described in MB (with a capital B). So, you always need to think about it taking at least 8 times longer than you think to transfer a file. Latency (how long it takes for a communication to be sent and then received) and efficiency (how much of the bandwidth is actually used by the communication protocol - 40% for TCP/IP!) make it even worse than that. So, if we have 100GB of scan data to transfer over a 100Mb connection (best case!): 100GB = 800,000,000,000 bits * 40% overhead = 1,120,000,000,000 bits / 100,000,000 bps = 11,200 seconds = 187 minutes. Over a Gb connection, that same file could transfer in 18.7 minutes.

Project Demographics Distribution and storage issues are obviously correlated to the specifics of each project as well. We asked four questions to profile respondent’s projects to better understand their frequency, duration, and size.

Looking at the entire base of respondents, we can see that frequent, short duration projects under 200 scans are the most common project profile for the firms our participants work for. Average size of the projects in scans and folder size are closely correlated as we would expect since the scan data makes up the bulk of the project data. Comparing these two charts tells us that there is a rough ratio of 1GB of project folder size per scan. While this isn’t a precise metric by any means, it is interesting as we can make some assumptions about typical scan resolution from that storage/scan ratio.

Data Retention Demographics Of course, now that we have all this data on… all this data; the remaining demographic question is how long to people hold onto it. This is a delicate question as different stakeholders have different legal requirements for data retention. Across all respondents, we can see that 10+ years had the highest response rate by a hair. Combined, over 60% of firms keep their data between 2 and 10 years. This is particularly interesting because most firms in the design and construction industry are usually obligated to retain data for 10 years from the completion of the project in case of HSW related lawsuits, etc… So, it was very surprising to me personally to see such a low number of respondents report that they were keeping data 10+ years!

Barriers to Adoption Comparison Our first and last question in the main part of our survey asked our respondents to rank the various barriers to adoption faced by firms implementing reality capture technologies into their practice. The first question asked our respondents to rate each of our five barriers to entry on a difficulty scale of 1-10.

Looking at the overall results, we see a lot of noise in the barrier to entry posed by the cost of the equipment, with three “peaks” in the data indicating that it is a minor problem for a lot of firms, right smack in the middle for the largest group of firms, and a major problem for a large number of firms. The remaining four questions show an interesting trend. Our respondents are reporting that each barrier to entry in the process of delivering a scan-to-BIM project are sequentially harder. So, field acquisition peaks as a minor barrier to entry (3), with registration and post-processing peaking out as a problem right in the middle of our range (5), data management and distribution comes in as a hard barrier to entry (7) while creating the deliverables peaks at a significant problem (9). These answers correspond to anecdotal information from USIBD members as well. Steady decreases in the cost of equipment over the last 10 years means equipment cost isn’t as big of a barrier as it used to be. Meanwhile, the technology development curve of each of the other barriers corresponds well with how long those technologies have been under constant development and improvement. Scanner firmware and field registration tools have done a lot to make field data collection easier, lowering the adoption cost of the equipment itself. Processing and registration tools have also seen a lot of incremental improvements, with newer tools focused on ease-of-use now in the market for several years. However, the technologies for distribution of the data and creation of deliverables haven’t been on the market as long and thus haven’t seen the full benefit of decades of incremental improvement.

Our second question was framed a bit differently. Rather than focus on the relative difficulty of the barriers, we instead asked participants to rank on a scale of 1-5 (1 being the highest) how much each of these inhibited the use of laser scanning on their projects and then averaged each barrier’s results by the total number of respondents. We can see that this generated a very different set of responses.

With this question, we saw an interesting reversal in the data! When in the context of an actual project with a set scope of work as opposed to overall difficulty, this data tells us that creating deliverables is the least important of the barriers. This makes sense as the deliverables are, of course, required for the project. So, while it may be the hardest step relatively speaking, it is the least likely to prevent someone from using reality capture on a project. From there, we see that the time and complexity of data acquisition in the field is now rated as the largest of the five barriers to performing reality capture on projects. Meanwhile, our other three barriers are right in the middle of the pack in terms of impact on projects. Note that our signal to noise ratio here isn’t great. None of our 5 barriers got more than .4 away from the average. So, that means there were a lot of mixed feelings about this question across our respondents.

Data Storage and Distribution Questions Now on to the meat and potatoes of our survey. These questions seek to understand the current state of the industry as it pertains to data storage and distribution on reality capture projects. Let’s dive in!

When asked where their firm typically stores the master copy of their reality capture data for projects, we can see that over 50% utilize some kind of network storage to do so. This is the generally accepted best practice. However, we still have just over one quarter of respondents keeping the master copy either on an internal drive in their workstation or an external drive connected to their workstation. These types of drives typically have no redundancy, so if there is a drive failure the data is usually lost. We’re also seeing a number of firms switching to using cloud storage options for the master copy, with a majority of that market going to generic cloud platforms like OneDrive, Google Drive, or DropBox, etc… We’ll take a look at these services in more detail later on in the survey. Looking at the local (user) copies, we see that most people are working on internal hard drives or external drives as we would expect. For a local copy, redundancy isn’t a concern as the copy itself is typically redundant. It is interesting to see over a quarter are utilizing their network storage for this as well given the significantly lower bandwidth and higher latency of such solutions. Some even report utilizing cloud storage for this, though most of these services use a local cache on disk for frequently accessed files, so we should assume these users are effectively using a local disk as well. Combining these various categories together, 69% of our respondents are working from a local copy of their reality capture data – though for 28% of them that may also be the master copy.

From an archival perspective, we can also see a strong correlation between where firms store their master copy and where firms keep their archive. Not surprisingly, those who keep their master copy on a workstation’s hard drive shift to using external drives once a project is archived. This is a cause for concern as more than a third of respondent’s firms are keeping their archive on non-redundant media, none of which are rated to last the legally required duration of time for backups. They may survive 10 years in storage, but there is certainly no guarantee! Backups are a critical part of our industry’s legal obligations, so hopefully this is an area where USIBD can raise awareness of these requirements! When we look at how that data is typically distributed to team members, we see that the distribution method is closely correlated to the location of the master copy of the data. This makes sense of course, though I was surprised to see such a low use of thumb drives as those work equally as well as external HDDs (cheap but slow). But, in terms of work patterns, the difference is not particularly relevant. Looking at how data is typically shared with external stakeholders (which we defined as being external members of the project team and the client / end user); we can see that mailing hard drives is still very popular. However, transferring the data over the internet has displaced physical shipping of data as the dominant method. Interestingly, generic cloud file services still dominate this workflow despite the availability of reality-capture centric solutions – likely due to the substantial cost differences between these services.

For those using generic cloud storage solutions we can see that Microsoft’s OneDrive, Google’s Drive, and DropBox are all close to the 20% mark in terms of market share (as is Other!). This was a multiple selection answer so that people using multiple platforms could identify all the ones they are using which is why the total responses exceed the number of respondents. For those answering “Other”, Autodesk BIM 360, Sharefile, and Amazon Web Services were the only write-in responses with multiple mentions. It should be noted that AWS answers imply that a company has developed or purchased a customer sharing solution, as does the one Azure answer we received. There were a bunch of other one-off answers which speaks to the plethora of solutions available on the market. When asked for their preferred solutions, we can still see a close correlation between which ones they’re using and which ones they prefer to use. However, those writing in answers to the first question almost invariably chose those as their preferred which is why we’re seeing a decrease in the overall share of the more common platforms in this second chart. It should be noted that many of people’s write in answers here included some colorful commentary about “preferred” being a euphemism for “the least bad” as none of these solutions are well tailored for the data profile of reality capture data. Many also noted that these services have significant limitations on single file size, total folder size that can be downloaded, or reliability of synchronization companion applications. So, bear that in mind as we consider the next set of solutions.

Cloud storage solutions focused on the distribution of reality capture data don’t suffer from the same limitations as the generic platforms, but they come at a higher price premium because of their specialization and relatively small scale. While only 25% of our respondents reported using these platforms at all, there was no similar commentary about the unsuitability of these solutions to the task. So, at least comparatively, it seems like these solutions do provide a better solution for distributing data than the generic solutions do. Cintoo has a clear market share lead in this chart, with “Other” being the second largest response. Amongst those responding “Other” we had only one repeat response – custom solutions built on AWS or Azure. Otherwise, each major vendor’s proprietary solution got a single response and there were a few more thrown in as well. When asked about their preferred solution, our one-off and write-in answers usually marked their answer as preferred as well. Our more broadly used solutions weren’t 1 for 1 in terms of being preferred. One could read into the preferred vs use response ratio suggesting Cintoo also has an advantage in terms of customer satisfaction over the other more broadly used solutions, though with only 38 respondents to the first question (multiple choice, so responses totaled 43) and only 17 responses to the preferred solutions question we shouldn’t extrapolate too much.

Given that these reality capture specific solutions are relatively new to the market and lack the day-to-day exposure the generic solutions have, we also asked a question to understand the reasons our respondents might not be using a more focused solution. From these responses, awareness is almost as much of a barrier as cost or data privacy concerns. So, you’re welcome RCCS vendors! It is also interesting that so many cited data privacy concerns given that over 60% of respondents reported transferring data over the cloud as the typical mechanism for delivering it to external parties, and that we got 189 responses from our 149 respondents as to the services they actively use! 17% also stated that these solutions don’t solve their workflow problems even though they’re often using even more limited generic cloud storage solutions to do the same thing. Anecdotally, the higher price tag associated with these services seems to drive higher expectations that the generic solutions are subjected to. It will be interesting to see if future iterations of this survey show a shift from generic cloud storage solutions to ones focused on reality capture data, and how the market share will change over time!

The Costs of Current Solutions In an effort to understand how the currently available solutions impact projects, we asked a series of questions to try and quantify the costs of various solutions on the project. As a starting point, we asked people to rank six costs we identified through prior surveys or feedback from USIBD members. The most costly of the six was ranked as 1st and so on with the least costly ranked 6th.

From here we can see that the time it takes project personnel to distribute the data is ranked by a thin margin as the most costly issue, with costs associated with storage and costs related to the interoperability of file formats ever so slightly behind. These three areas are where our respondents perceive the most cost impact to their project, though again these all hover close to the median value of 3.5 suggesting that there isn’t a lot of clarity across all firms and firm sizes. If we look at each of these more closely though, we can see that the lack of a clear answer has much more to do with the respondents not knowing the actual costs of these issues on their projects. As you will see on the next pages, “I don’t know” is the top response for each question where we ask for a quantitative assessment of costs except for the costs of shipping per project. This raises an important issue for our industry – it would appear that a large number of our respondents are not aware enough of the costs these pain points cause to feel comfortable making a guess as to the impact on their project’s profitability. This may also explain the low adoption of reality capture focused cloud storage and distribution solutions as they cost a lot more but without the costs of current practices being clear the value proposition is equally unclear.

Top provide some context for this question, cost per gigabyte is a common metric provided by cloud storage platforms, vendors providing NAS hardware, and even hard drive vendors. Total costs of ownership for these solutions (including equipment costs, operation costs, and maintenance costs) typically range in the 50 cents per gigabyte per year up to 10 dollars per gigabyte per year for the highly performant NAS solutions designed for 100s of users to access simultaneously. If we take 100GB as the median project size (from our demographics section) and calculate out actual costs, it is certainly possible to achieve the $100 per project that 46 people selected as their response, but only by using low end internal or external HDDs as your solution. As soon as you start upgrading to any reasonably redundant storage solution you rapidly exceed that $100 dollar per project barrier by a large margin (5X!). Given that roughly half of our respondents stated that their firms were using some kind of NAS to store their active data AND to archive projects, we can extrapolate that at least half of our firms are spending between $500 and $5000 for the five year period asked about in this question. However, it is clear that a lack of knowledge about real storage costs is leading to a significant underestimation of this cost in our respondent’s answers.

Shipping is a project cost that is clearly visible via a few receipts – so it is relatively well understood overall. Most respondents report spending less than $100 per project on average projects, which makes sense given that the majority of firms are utilizing cloud services to distribute data. The roughly 40% of respondents that rely on shipping of hard drives or thumb drives to distribute their data are still likely spending less than $100 on the average project unless that data exchange is happening frequently or the project’s schedule demands incur overnight or same-day delivery rates. Overall, these answers correlate well with the project information provided at the beginning of the survey. As a mechanism to understand the costs of the time and delay associated with the transfer of reality capture information between physical locations, we began by asking the user to answer questions about the time lost due to the transfer process and the impacts of that time lost in terms of project delivery.

For time lost waiting for data transfers to complete, roughly one third of respondents only saw a few hours of wait time, and three quarters of respondents said this took a day or less. If we compare this back to the average folder size of reality capture projects and take into account the typical internet bandwidth these responses make sense. However, we also had 40% of respondents say they typically ship physical copies to distribute data, so it would appear that there is also some underestimation of the delay incurred in the transfer of data in these numbers. One observation during the review process is that many times the sender or recipient is only aware of half of this penalty as they see the upload, but not the download. Similarly, with shipping the sender isn’t aware of how long it takes to receive, open, and transfer the data locally at the recipient’s side (and vice-versa). So, it may be reasonable to assume these numbers are underestimated by a factor of 2.

When asked to identify the impacts this delay had on their projects, most respondents identified at least one project impact as a result, and many respondents identified selected two or even three challenges the delays in data delivery can cause. This survey was initially conducted before the COVID pandemic had a significant impact on offices, so it would be interesting to see if the shift to work-from-home during the pandemic casued any significant changes in respondent’s opinions on this question. One point of interest, most of the “Other / No Issue” responses had write-in explanations that there was no time lost at all due to transferring data. While this is certainly a small percentage of responses to this question, it represents one sixth of the total respondents. Many of these noted that they do all their work in house (no transfer occurs) or that they don’t send the reality capture data to their clients at all and instead send BIM or CAD files as the only deliverable. We did have a few write-in responses that because of these challenges the respondent’s companies pass on work they’re qualified to perform because they’d need to collaborate externally and don’t find that to be feasible. Not pursuing work because of these challenges speaks to a significant business cost far beyond the options in the follow-on question.

Having laid a framework by which to evaluate these costs, we then asked respondents to quantify the cost in monetary terms. Again, we see a large number (50%) respond with “I don’t know”. Of those willing to hazard a guess, we see a much flatter distribution of answers. One sixth of respondents said it was less than $100 of cost incurred from the time spent managing the transfer of reality capture data. This exactly matches the number of respondents who selected “Other / No Cost” in the prior question. So, at least we’re getting consistent results! The remainder who thought there was a real cost were split more or less evenly between the remaining four selections. Of course, none of these selections adequately capture the costs of passing on work because collaborating with other consultants is too challenging.

Asking our respondents to provide an amount of time spent managing multiple copies of data yielded a similar number of “I don’t know” responses. However, amongst those who provided an answer the responses were weighted towards the low end of our selection choices. Given that a majority of those who had an answer selected “1-4 Man Hours” I wish we had broken this down into smaller buckets so we could get some better granularity in this range. If we make some estimates about typical burdened and billing rates we can extrapolate that the costs associated with data duplication issues on most projects will range from $30 at the lowest end up to $450 on the high end of the 1-4 hour range. Looking at billing rates the numbers are a little more impactful. Given, these aren’t the real costs absorbed by the project. However, they are representative of the loss absorbed by the business if that hour (or 20) could have been spent on additional billable work instead.

Costs associated with file format interoperability ranked third in our list, but was very close to the median answer. Our respondent’s answers to our questions were equally inconclusive.

When asked if current proprietary file formats met respondent’s needs for data storage and distribution the answers were almost perfectly split with a tiny negative lean. The answers were slightly more positive for industry standard formats such as E57, but far from a glowing recommendation of said formats. We also queried our respondents about the importance of extensibility in their formats, and this at least should provide a very clear answer back to vendors and standards bodies alike. Custom metadata matters!

Our last pain point to evaluate (and tied for fourth in the respondent’s ranking) revolves around archiving and data retention. Our respondents were relatively evenly distributed across these five concerns. Again, this was multiple selection so we have 328 total responses from our 149 respondents. This means that on average respondents had at least 2 concerns when it comes to their firms’ archiving and data retention policies.

The selection with the largest number of responses was focused on redundancy of backups. Considering the large number of firms utilizing external drives for archiving or even their active master copy, this isn’t surprising to see. It also means that if these firms address these concerns by investing in redundant storage arrays and off-site backups for disaster recovery that their storage costs will increase considerably. As such, storage costs for achieving redundancy and keeping data the required amount of time is a logical second place answer, as is our close third place concern of whether the data will even be usable in 10 years. This last concern is both a function of hardware (external drives are not designed to keep data safe for 10 years) and software (will the format be abandoned and unusable). Based on the answers to prior questions and the requirements on software vendors to support the 10-year life span of data in our industry, the hardware side of the concern seems far more serious. Perhaps unsurprisingly, regulatory compliance ranks as the smallest concern – very much in line with the actual archival policies at most respondent’s firms. Cybersecurity was also less of a concern at the time of this survey, though this may change over the next few years given the increase in ransomware attacks within our industry specifically.

CONCLUSION When we put this survey together initially, we were trying to answer a broader question about the significance data distribution and delivery played in inhibiting the use of reality capture on projects within our industry. Shortly after we wrapped up collecting responses COVID changed the playing field out from under us. As such, it is important to view this report as a snapshot of the state of the industry before COVID occurred. We are hoping to run a second iteration of this survey next year to see what’s changed over the course of the pandemic. However, we were able to draw several interesting conclusions from this snapshot. First, that while our industry does see data distribution and delivery as a challenge to the adoption of reality capture – it is just one of many. So, while improvements in this area would be welcome by most respondents, it isn’t going to make or break any decision. Second, that there is a lot of ambiguity within the building documentation profession around archiving requirements and how AEC regulatory requirements apply to the data we collect. This is an area where we believe USIBD can provide some clarity to practitioners by better explaining what firms should be doing to meet regulatory requirements and to provide best practice guidelines so firms can make better decisions about how they retain their data moving forward. Third, we can clearly say that the internet has supplanted physical copies when it comes to distributing reality capture data in our industry. While a 60/40 split isn’t a landslide, it is still a significant margin. However, services that focus on reality capture data are only used by a small minority of respondents. Most firms still prefer to use larger generic services due to the lower cost of those services. Fourth, I think we can clearly say that current file formats are underwhelming at best in terms of meeting our industry’s needs for efficient and transportable data. While we didn’t dive into the details of why people’s needs aren’t being met in this short form of the report, we did get a lot of write-in answers as to why people answered as they did. In summary, there are too many options and there is a loss in fidelity of the data when moving between formats whether they are proprietary or not. So, there is a lot of room for improvement on this front. Last, it seems like the actual costs of storing, managing, and distributing reality capture data are not well understood by practitioners in our industry. To some extent this is understandable given the level of techno-babble one has to understand to understand where the costs arise. However, these costs do have distinct business impacts as shown by our respondents’ answers to qualitative questions. However, the same respondents struggle connecting those impacts to any quantitative metric. So, there’s definitely work to do to advance our general understanding of these issues and the costs they entail. We will close by pointing out that there are some more definitive trends in the data when we isolate specific industries or segment the data by the size of the respondent’s companies. So, if you’re interested in the detailed report with demographic breakdowns, make sure to join the USIBD so you can access it!
