What is AR Augmented Reality?

Using advanced camera and sensor, AR blends physical surroundings with computer-generated information, presenting in real-time. The technology has been used for several years in the video game and currently this “augmented” experience is creating waves in construction, providing opportunities to improve project lifecycle.

Blending digital and physical outlooks, augmented reality is assisting construction teams to become competent, precise, and confident in their projects. The AR global market is estimated to grow $90 billion by 2020. Instead of substituting workers on the field, AR can be used to improve the ways humans and digital machines collaborate.

As technology continues to grow, augmented reality will turn out to be a vital tool with the potential of transforming the future of the construction industry. Read on to learn about the applications of AR in 2020 and beyond.

Augmented Reality (AR) 

As per Construction World, though virtual reality has been a developing trend over the last few years, it will become outdated compared to augmented reality uses and benefits. AR presents the fact to visualize the real world through the camera lens. The technology will open new opportunities for the construction industry even if it comes with a cost. It’ll revolutionize the project and the way of building things. Many consider that instead of using safety goggles, they will plan and plot sites before breaking ground.

How Augmented Reality works?

  • 3D Model Creation, combining construction data
  • Users wear an AR device, orienting to their viewpoint
  • Building data presented digitally over physical surroundings in real-time

While virtual reality is strictly a digital experience, augmented reality pools real and digital into an immersive setting. AR projects 3D images on an individual’s physical settings as they walk through with a mobile device.

Through GPS and cameras, AR presents actual data geospatially, updating and exhibiting the essential information as the user moves through the building space. Data like schedules, working specifics, and structural plans are easily accessible, letting users automate the construction process and make decisions on site.

Applications of AR in Construction

Augmented reality is used to improve efficiency, safety, streamline collaboration, manage costs, and boost the project. Let’s check out the applications of Augmented Reality in construction.

1. Project Planning

Innovative developments in augmented reality help to produce 3D models directly on a 2D plan. Using 3D Modeling software and BIM (Building Information Modeling), 3D Modeling companies in the USA provide interactive models of building projects and present to clients at the onset of a project. The clients thus get a realistic project outcome and make desired changes before construction. Client involvement prevents expensive changes later.

AR help teams conduct walkthroughs of the complete project before execution, inspecting the structural details and components. The foresight prevents delays, reduces cost overruns, and identifies mistakes before surfacing.

2. Automated Measurements

Augmented reality helps to measure a space’s physical properties, including the height, width, and depth. Construction companies can integrate the details into the models, letting them produce more accurate structures with a comprehensive view of how the project will appear. Accurate measurements in construction ensure efficacy in the project time with the exact requirement for the labor and materials.

Besides planning, augmented reality allows field workers to automate measurements on-site at the time of construction. Wearing an AR unit, workers can tap to make automatic measurements of the constructed components and compare them against the measurements detailed in the building models. Consequently, the workers can find inconsistency in the structures and correct the problems areas to avoid higher costs and delays in construction.

3. Project Revisions

Augmented reality helps the users to make modifications to building models directly on site. Through a headset or a mobile device, workforces can exhibit interior and exterior views of construction and make alterations to the virtual plans while keeping a view intact. For example, engineers can remove and relocate walls or other components or change the layout using just a few taps on an AR device.

AR helps construction professionals to troubleshoot mistakes in a virtual environment before making changes to the structure. As digital data is updated continuously, it eliminates the guesswork from any project change, thus streamlining the workflow and avoiding material waste.

4. On-Site Project Information

The ability to pool digital data and documentation with the physical view is a game-changer. Information like the places of pipes, outlets, walls, switches, and ventilation can be accessed directly on-site in layers which can be toggled on and off. Data recovery lets field workers to monitor a project against building plan efficiently and ensure successful completion. For example, a contractor using a headset can see the locations of the drill holes in the building plans to let them make the additions appropriately and moving the project.

AR allows users to virtually see the building progress against schedule, offering project management. 

5. Teamwork

Construction projects entail collaboration among several project teams, including, electricians, plumbers, designers, and managers, and more. An effective partnership confirms that a project gets completed on time as per the proposed budget.

Nevertheless, all stakeholders involved in a project are not always present on a job site. If any error crops up that needs to be addressed by all parties involved to review blueprints and make necessary changes. AR lets users take notes and share video views of an error or design issue and send information to remote teams in actual time. Both on-site and remote team members can consult with each other and work with the desired information, reducing the time and costs to make a decision. 

6. Safety Drill

Safety is a challenge in the construction industry. Safety programs take time and money and aren’t always appropriately communicated to the workers. Using an AR headset, workers can be provided training on virtual drills, instruction, and safety scenarios. The direct learning improves awareness of safety, offers intuitive practice, and reduces training costs and interruption.

Augmented reality is also explored to make virtual models of equipment like cranes and lifts. Workers can use their headsets to practice operating heavy machinery in a safe and virtual set up, improving their learning and progress.

Benefits of AR Augmented Reality

  • Accomplishing a project on time & budget with the right plan 
  • Ensuring project accuracy from start to finish, preventing rework, saving building costs
  • Overall precision & efficiency lets construction companies increase confidence in projects
  • Improving client relations, creating long-term ROI

Road Ahead

Even though large construction firms have implemented AR, it will become more accessible in the future as technology reduces costs. Several companies are providing the technology on a per-project basis and with free trials, letting construction managers experiment with new technology and adapt to business. From removing errors to offering insight, augmented reality can effectively streamline the product lifecycle.

Special Mission for the Blue and Golds

Special Mission for the Blue and Golds

The U.S. Naval Academy maintains a tradition of producing young men and women who will go on to lead one of the country’s five branches of the military. The academy expects excellence in the classroom and excellence in the sports arena. A plan was developed to make modifications to the Navy-Marine Corps. Memorial Stadium in Annapolis, Maryland, one CSDA member had to be at the top of their game to complete a portion of this challenging project.

Purpose of Renovation 

The stadium was opened in 1959 and is home to the Navy Midshipmen football team, the Navy Men’s Lacrosse team, and the MLL’s Chesapeake Bayhawks Lacrosse team. The Naval Academy needed to renovate a section of a mid-level wall in the 34,000-seat venue to incorporate elevator access to new skyboxes at the east end or “gold” side of the stadium. There was only a short time available to carry out this renovation, as the graduation ceremony for the 2010 Naval Academy class was about to take place just two days after the work was due to start.

Stadium Details 

The mid-level exterior wall of the stadium consisted of two 8-inch-thick concrete walls with a small space between them. An opening measuring 14 feet wide by 4 feet tall was required and was to be included being safety sealed. Besides, further cutting work would be necessary some weeks later inside the stadium to allow the general contractor to connect the new skyboxes to the existing structure. This work would consist of cutting 136 feet of a concrete wall that varied in thickness from 8 to 12 inches.

Special Mission for the Blue & Golds

Project Stakeholders Involved in the Stadium Renovation 

Structure Tone, Inc. of Washington, DC, was the general contractor for the stadium renovation work. The company selected Viking Enterprises as the demolition contractor for the job, who then contacted CSDA member G&S Concrete Cutting of Rockville, Maryland, to perform the specialist cutting work that would create the specified opening. 

Quote from Operation Manager

“We were very proud to be called in on such a fast-paced, high-profile project,” said Rob

White, Operation Manager for G&S. “Viking Enterprises came to us because of our professionalism and ability to work within a strict time.” 

Proposed Plan for Creation

For the creation of the 14-foot-wide by 4-foot-tall opening, G&S proposed a plan to use a diamond wall saw to cut the section free. The general contractor was in agreement with this plan, and no other methods of demolition were considered. Alternative demolition methods, such as jackhammers, would have produced large amounts of debris and much more time would have been required to attain the precise dimensions of the specified opening. Before work commenced, G&S needed to subcontract a crane operator for the next day to hold the cut section of concrete during cutting and remove it. A 100-ton Liebherr crane was supplied. The following day, G&S arrived on site to set up equipment to begin cutting the opening. An operator core drilled two 4-inch-diameter holes through both 8-inch-thick outer precast and inner cast walls using a CB748 core drill from Diamond Products. The holes were to be used to thread through crane connections for the safe removal of the sections, once cut.

Implementation of the Plan

The cutting team, working approximately two stories up in a boom lift, used a hydraulic hand saw with a 20-inch Diamond Products blade to perform the wall cuts, before switching to an ICS 880 series chain saw to complete the corner cuts. Cutting and removal of both inner and outer wall sections, weighing 9,520 pounds and 5 tons respectively, were completed within five hours of the first day’s work. Following the successful completion of this cutting work within a short time scale, G&S was contacted several weeks later for another job.

Within three weeks, the contractor was asked to return to the stadium to cut and remove 136 linear feet of concrete from the top wall. The cutting work was split into eleven 12-foot-long sections that ranged from 8 to 12 inches thick. Some parts were to be cut by wall saw and removed by crane, while other sections had to be cut free using a hand saw and placed onto pallets for removal.

Corner cuts were made using a diamond chain saw.

Time Taken

New skyboxes were installed at the top of the stadium after cutting because of a 52-foot-long by a 5-foot-wide overhang on the part of the wall would not allow access by the crane. The team from G&S took 12 days to cut and remove the 12 sections of concrete. A Hydro stress wall saw from Tyrolit, with a 36-inch-diameter blade from Diamond Products, was used to make the cuts and wet vacuums were employed to collect and contain any slurry. Cutting of each section took three hours, while removal by crane took 30 minutes for each 4.2-ton piece from inside the stadium.

Challenges Faced 

The use of pallets to remove some of the cut wall sections worked well as an alternative method of removing those concrete sections with an overhang, but there were a couple of other factors that presented challenges for G&S. Water supply for cutting and the positioning of hydraulics at the work area required some extra effort. The cutting area was located 250 feet above the nearest water supply, so a water hose had to be run-up to the top of the stadium to allow wet cutting. The foundation and sections of the steel structure had already been set in place to construct the new skybox, so the positioning of the contractor’s truck and hydraulic equipment was limited. The general contractor was able to remove a section of fencing around the stadium to move the truck and equipment closer to the work area.

Cut wall sections were lifted out by crane or placed on pallets for removal.

Solution – Problem Solving Approach for Overcoming the Challenges

  • A 60-foot boom lift was utilized to position operators at the work face; therefore, safety harnesses were required to be worn and secured to the elevator at all times during cutting.
  • All other items of personal protective equipment were worn by the contractor’s team to ensure safe operations.
  • A 20-amp CB748 Diamond Products core drill was used to create the holes for the crane connections. 
  • Diamond Products also supplied the 20-inch-diameter blade for the hand sawing portions of the work, with an ICS 880 series chain saw used to perform the corner cuts.
  • Wall sawing of the 12-foot-wide sections at the top of the stadium was completed using a Hydrostress V465D1 saw from Tyrolit with a 36-inch-diameter blade from Diamond Products.

Result

  • The total amount of concrete cut at the Navy-Marine Corps. Memorial Stadium was 570 linear feet of 8- to 12-inch-thick wall sections. Both stages of the project performed by G&S were completed on time and within budget.
  • The project was a design-build that took only five months from design to completion. The new skybox area at the stadium was opened in September, and now fans of Navy’s sports teams can cheer on the blue and golds from this vantage point. 

Testimonial from CEO -”We are happy to have completed this work for the Naval Academy, and are pleased with the results,” said Preetie Ghotra, CEO of G&S.
