10 SCAFFOLD SAFETY ESSENTIAL

7 Major Construction Technology Innovations to Watch in 2018

2017 was a big year for technology innovation in the construction industry, and that pace is unlikely to slow in 2018. This is good news for companies that embrace technology to improve cost, safety, efficiency, and quality of construction.

If you plan to be among the leaders, here are 7 construction technology innovations to watch in 2018.

1. Virtual Reality

Virtual reality has finally made its way out of the gaming industry fully into the (pun intended) real world. Winter Construction used 4D virtual reality models to fully immerse owners and other stakeholders in the environments of planned construction during planning and design stages for major projects including an airport hotel and a zoo parking and entertainment complex.

In both cases, walking stakeholders through a fully interactive immersive experience prior to finalizing plans allowed them to win buy-in and produce plans that fully met expectations. It also allowed them to work around unique conditions including the schedule needs of zoo animals and views of aircraft take-offs and landings.

While virtual reality has previously been the domain only of the most cutting edge organizations, it is becoming increasingly mainstream, and increasingly in demand from owners. 4D environments allow construction companies to plan every aspect of the construction project, improving everything from safety to efficiency, and delivering a more consistent and quality final product.

2. Augmented Reality

Augmented reality provides ability to literally walk through designs via tech like DAQRI Smart Glasses

While virtual reality allows users to “walk” through 3D and 4D model environments without actually moving their feet, augmented reality allows users to walk through real 3D environments, with their feet, while gathering and/or viewing additional real-time information about that environment.

For instance, a new iOS app called MeasureKit allows users to point their phone or iPad at an object or building component, and interact with that component through the screen in three useful ways: Measure, level, and place objects.

We predict that many new augmented reality applications will arrive in 2018, and that some of the existing applications will become mainstream, such as the ability that BIM 360 Glue provides for subcontractors to point a device at a component and get information from the 3D models laid against the image that is framed in the device.

3. Wearable Technology

The construction site has never been safer than it is today, and we think it’s only going to get safer with the introduction and mainstreaming of wearable technology. Companies like Triax offer wearables that track where workers are on the job site, alert them in real time of potential hazards, and identify when someone has tripped, slipped, or fallen, so help can be sent right away.

We think there will be more and more products like Triax available, and that companies who take advantage of them will become more and more in demand, especially as the industry begins to develop benchmarks for safety that become part of the bid process.

4. Machine Learning

While we’re on the topic of safety, take a look at some of the past year’s innovations in machine learning, and their implications for the new year. Smartvid.io, for instance, aggregates visual data from the job site and intelligently analyzes it for a variety of purposes including safety, quality, progress tracking, and marketing.

Smartvid.io constantly analyzes photos, videos, and other visual data coming from the job site, and looks for safety violations (failure to use PPEs, for instance), as well as tagging items by room and associating them with plan data. This allows folks in the job trailer or the office to quickly find visual information about the site without having to sort through masses of data. Additionally, it makes it easy to identify visual data to use for marketing purposes.

We think technologies like Smartvid.io are going to transform the way companies do business in 2018, by making existing data more accessible and easier to use to improve everything from quality and timelines to safety and marketing.

5. Prefabrication

Prefabrication is hardly a new innovation in itself. The construction industry has been using prefabrication in various applications for decades. However, new technologies are making the benefits of prefabrication easier to access, and changing the way the construction industry integrates prefab into the process.

For instance, ManufactOn provides a mobile technology that provides complete visibility into the prefabrication process, so that anyone involved in the project can see what is being manufactured, where it is the process, and when it will be delivered. A new integration with BIM 360 Docs will make it possible to view that information in one workflow from beginning to end of the design and build process.

We predict that companies who take advantage of these technologies to streamline and increase their use of prefabrication will gain competitive advantage in 2018.

6. Predictive Analytics

Often, the difference between a successful construction company and a struggling construction company lies in your ability to manage risk. Predictive analytics is about to make risk management much easier.

In 2017, BIM 360 Project IQ ran beta tests with leading edge companies to see how much we could help them manage their risk through the use of predictive analytics. Project IQ analyzes data from subcontractors, materials suppliers, design plans, and the site itself to analyze risk factors based on historical data. It provides a dashboard where GCs can identify which elements of their project are highest risk and need attention, and allows them to drill down to see the reasons for the risk assessment. Project IQ learns both from past data and from how the GC interacts with the information it provides, in order to continuously provide better and more accurate risk assessments.

We expect Project IQ to roll out to the wider industry in 2018, and we predict it’s going to massively improve how its users manage their risk.

7. Connected Job Sites

Communication delays between the job site, trailer, design office, and engineering can be costly and aggravating. In short, a disconnected job site can quickly burn up your profits.

Fortunately, job site connectivity is catching up to becoming easier and easier to achieve. With a connected job site, everyone on the site has access to up-to-the-minute drawings and documents, and holds the ability to file RFIs and issues in the palms of their hands. Likewise, everyone in the trailer and design and engineering has immediate access to everything that is happening on the job site.

Communication around RFIs and issues is reduced from days or weeks to mere hours or minutes. Mistakes due to miscommunication are nearly eliminated. And change orders and rework are significantly reduced. We think very few construction companies will thrive in 2018 without moving toward the connected job site.

TOP 10 WAYS TO KEEP YOUR PROJECT ON TIME AND ON BUDGET

There are many factors that can affect the success of a project. Following are 10 of the most common issues experienced during insulation installation and solutions to ensure they don’t negatively affect the project. These issues tend to crop up repeatedly, so it is important to continually reinforce these lessons to project teams. By avoiding these issues, you can help ensure your project meets the planned deadline and budget.

1. Problem: Scheduling and Sequencing of Work

One common issue is the lack of a schedule or the use of a schedule with inadequate time allocated for insulation activities. It is fairly common to have partial releases on a site when part, but not all, of a section is completed. This can hinder the efficiency of work, as well as causing multiple trades to be working in an area at one time—leading to slower work schedules or the need for repeated visits to a part of the project. Staying on time is also critical—work that is released late can cause increased costs because workers might not be able to access the area they need without working over or through other trades.

Solution

These issues are mostly avoidable if those managing the project are aware and take appropriate action. Solving these problems with the general contractor or mechanical contractor as or before they occur, rather than waiting, can ensure the overall project stays on budget and is successful. Proactive communication prior to the start of project is a must. Additionally, it is advisable to hold weekly project status meetings to discuss any issues and to communicate the current state of the project. If there are delays, it is incumbent on the insulation contractor to provide notice on cost impacts as soon as possible or per contractual requirements.

2. Problem: Access

Failing to include a clearly defined access plan and the associated costs in the bid has a huge potential financial impact. Many times scaffolding, man lifts, and other forms of access to work areas are underestimated or not clearly enumerated in the request for proposal (RFP) or a contractor’s proposal. Once again, cost overruns due to underestimated scaffolding or lift costs as well as loss of productivity are likely to occur when there is not an agreed-upon access plan with the client and the associated costs are not contained in the proposal.

Solution

During the bidding process, make sure the insulation contractor qualifies and clarifies access plan requirements and costs. This must be agreed upon and part of the contract document. Prior to mobilization, it is helpful to meet with the insulation contractor to review the access plan requirements. It should also be revisited during weekly project status meetings.

3. Problem: Damage to Installed Insulation Systems during Construction

Insulation being walked on and damaged by other trades during construction is a constant
problem on projects. This may lead to conflict on the site if there are disagreements about who caused and is responsible for the damage. It can sometimes fall to the insulation contractor to correct all damage to the system during construction. This frequently results in a contentious and costly issue, often near the end of the project.

Solution

Damage to insulation systems is likely to occur on any jobsite. The issue can be mitigated, however, with proactive and constant communication between the trades. It is advisable to bring up the issue at weekly meetings and ensure there is an awareness down though the field level. For the insulation contractor, it can be useful to create a damage-to-work document complete with pictures and a description of the damage. This document should be updated weekly (must be a cumulative, living document) and transmitted to the general contractor or mechanical contractor each week, with cost estimates to repair the damaged items. Damaged insulation compromises the integrity of the system, and even opens up the potential for system failures. Being proactive about preventing damage to the insulation will save the building owner money down the road.

4. Problem: Material Storage

Onsite material storage that is not in close proximity to the work area can be costly. Many times, cost overruns for material handling and loss of productivity occur because these costs aren’t accounted for at bid time or there isn’t a good project logistics plan in place from the start. Remember, if the installers don’t have the materials, they can’t put them on, potentially leading to project delays. Another potential issue is weather—if the materials aren’t stored in a protected area, they can be at risk of damage from rain or high winds if they aren’t secured. If the insulation becomes wet, it may need to be reordered incurring additional costs and delays.

Solution

Make sure you receive detailed material storage and laydown requirements for the project in the contractor’s proposal. Laydown requirements refer to a specified place where material will be stored. This must be agreed upon and be part of the contract documents. Costs for this function must also be included in the contractor’s estimate. It is important to ensure this is clear prior to mobilization, and to abide by the terms and conditions contained in the contract.

5. Problem: Interferences

Many times there is a lack of adequate room to install the specified insulation thickness. This can be caused by a design that doesn’t leave enough room for the required insulation thickness or other trades installing parts of the job out of sequence, lessening the available area for insulation. Unfortunately, sometimes the insulation’s thickness is modified to fit the available space. It is never recommended to allow this, as it could cause performance issues with the specified insulation system down the road. Modifying the system without engineering approval could lead to costly rework requirements. Additionally, the field modifications increase the cost of installation by slowing productivity down on the initial installation. Finally, a system without adequate insulation thickness may not run as efficiently, leading to higher operating costs down the road. Other interferences include physical barriers such as temporary hangers. The insulation contractor will have to work around the temporary hanger and leave space for where the permanent hangers will go, which will necessitate multiple run-throughs and can increase project costs.

Solution

The first step in preventing this issue is for the mechanical engineer to know the pipe size and design enough room for the appropriate amount of insulation. It is particularly important to design enough space for valves to be insulated—this tends to get overlooked and can lead to system failure if the valves do not have sufficient insulation. Staggering the valves can be one option, as it can be hard to fit the proper insulation around valves if they are in close proximity. At bid time or prior to the start of the project, it is advisable to meet with the mechanical contractor to discuss space requirements needed for the total finished specified insulation system. This should be followed up with a written document detailing the meeting. The insulation contractor should notify the owner and general contractor that the lack of appropriate space requirements may result in an insulation system that cannot be warranted. Insulation systems should not be modified from required thicknesses due to lack of appropriate space requirements. This may result in insulation system failure as well as costs impacts to the client. Solving these issues upfront will save time and money. In terms of other interferences, such as temporary hangers, proactive communication between the trades responsible for these systems can help them establish a schedule to minimize repeated trips and keep costs under control. These types of issues should be discussed in initial planning meetings and revisited in weekly meetings.

6. Problem: Lack of Proper Workflow (Jumping Around)

Incomplete releases of work are common and always quite costly to the insulation contractor and ultimately to the owner. They often cause multiple trades to be working in one area at the same time, and also necessitates multiple run-throughs by different trades on site, which can cause work to go more slowly. Normally, they are a result of a lack of good scheduling or when a client—who could be the mechanical contractor, general contractor, or owner, depending on the project and who the insulation contractor is working for—gets behind and must rush to get back on schedule. This can be disruptive to overall progress and lead to stalls in progress, causing potential delays to the overall schedule.

Solution

During the proposal process, discuss and clarify what is expected regarding minimum expected work backlog (percentage of effective work available) for the insulation contractor prior to mobilization. The general contractor, building owner, or mechanical/
plumbing contractor should sit down with the insulation contractor and come up with a schedule to minimize delays caused by improper workflow. It can be helpful for the insulation contractor to provide weekly reports to the client as to the percentage of available work released ahead, as well as completed, by the contractor. Cost impacts due to jumping around should be given as soon as possible or in conjunction with contract requirements.

7. Problem: Leaving Welds-Fittings-Hanger Points Open

Many times specifications or contract documents call for welds and fittings to be left open for testing and inspection purposes. This requires the insulation contractor to work multiple times in an area to complete the insulation system. This will increase the cost of installation and can also cause delays.

Solution

During the bid process, get pricing from the contractor on the impact that multiple run-through will cost to get an idea of the potential impact from this issue. It is good practice to meet before the project to attempt to reduce or eliminate having to go back and fill in welds or fittings. As always, proactive communication and collaborative planning are key to avoiding issues that cause increases in budget or project delays. Minimizing the need to go back and re-insulate can decrease costs and save money for the building owner or manager.

8. Problem: Sub-Tier Insulation Contractor Status

Many times there is no direct communication link with the prime contractor and other trades by the insulation contractor. This typically results in work being done out of sequence and can potentially have a costly impact for the insulation contractor. It is most prevalent on commercial work and sometimes occurs in the industrial environment as well.

Solution

Recognize and be pro-active on communication and payment issues. Make sure to include the insulation contractor in weekly subcontractor site meetings and be prepared to discuss relevant issues at the meeting. Document the discussion in written format so everyone is on the same page—communication and documentation are vital to preventing slowdowns and additional costs.

9. Problem: Hot Spots/Cold Spots

We have all encountered warranty issues that more than likely could have been avoided at the time of initial installation. These issues can potentially be costly and lead to headaches for the building owner or manager. Hot or cold spots almost always result from workmanship issues—insufficient insulation on fittings, gaps in insulation, etc. In a cryogenic system, improper insulation can lead to freezing and system failure, which can lead to huge repair costs for the building manager or owner.

Solution

Continuous quality control (QC) and quality assurance (QA) are the keys to preventing hot and cold spots in a system. A high-quality contractor should provide specific craft training on the installation details of the specified insulation system prior to each person beginning work on the project. Additionally, QC/QA inspections should be done daily to ensure compliance with project-specified and industry-standard installation requirements. In this instance, hiring matters. Make sure you enlist the services of an insulation contractor that is proactive about these issues and has a QC/QA process in place for the project.

10. Problem: Poorly Installed Insulation

Generally speaking, if an insulation system visually does not look good, it probably won’t work well. Gaps, insulation that isn’t securely fitted to the pipe, or other installation issues can lead to severe performance issues down the road. As with other issues, improperly installed insulation puts the system at risk of inefficiencies or in the worst case, failure.

Solution

Again, this will come down to hiring a quality insulation contractor. During the bid process, inquire whether the contractor provides specific craft training on the installation details of the specified insulation jacketing system. Additionally, make sure they will perform QC/QA inspections daily to ensure compliance with project specified and industry standard installation requirements.
