For the university, the 35,000-seat outdoor college arena\u2014which hosts football games, professional soccer matches, and other public events\u2014offered an opportunity to engage in sustainable building practices."},{"acf_fc_layout":"image","image":580092,"image_position":"right","orientation":"horizontal","hyperlink":""},{"acf_fc_layout":"content","content":"The construction of Snapdragon Stadium involved recycling all the concrete from the stadium that San Diego\u2019s former professional football team, the Chargers, used to play in and redistributing it as the subbase material for the roads that service the university\u2019s new stadium and 132-acre Mission Valley campus. This entailed processing more than a million cubic yards of materials from the demolished arena at an on-site batching plant and moving it to the adjacent construction site.\r\n\r\nOCMI, Inc., a California-based firm that provides estimating, scheduling, and project and construction management services, oversees capital projects at the university. The firm needed a solution to help track the movement of materials around the construction site and provide progress reports to stakeholders.\r\n\r\n\u201cWe needed a way to track and understand how those materials were being moved in conjunction with the schedule and be able to validate [the information that contractors] were giving us,\u201d said Justin Dorsey, project executive and preconstruction manager for OCMI.\r\n\r\nDorsey and his team elected to use drones to fly around the project site, along with Site Scan for ArcGIS to collect, process, and analyze imagery. This would allow them to not only keep tabs on materials but also monitor construction and provide progress reports and metrics to stakeholders at the university.\r\n\r\nThis was a high-profile project for the community and part of a larger, multimillion-dollar construction venture, so Dorsey was determined to do the best job possible.\r\n\r\n\u201c[The old stadium] was a relic to San Diego residents. So that was quite a big deal that the stadium where so many memories were made was going away,\u201d he said. \u201cKnowing the gravity of that project\u2026we had to knock it out of the park for the community.\u201d"},{"acf_fc_layout":"quote","image":580132,"text":"Site Scan fit the bill for what we were looking for, and it gave me the flexibility to scale.

A Flexible, Scalable Drone Solution<\/h2>\r\nIn searching for the right software to use with drones, Dorsey found the scalability of cloud-based Site Scan to be a defining factor. He also liked the tools that came with it.\r\n\r\n\u201cSite Scan fit the bill for what we were looking for, and it gave me the flexibility to scale,\u201d he said. \u201cMy goal is not for me only to fly but for me to grow [drone use] as a business line within my organization and run it from the enterprise level.\u201d\r\n\r\nAnother benefit of using Site Scan was that it was \u201cdrone agnostic,\u201d according to Dorsey. Other solutions he researched required users to purchase the drone along with ground control points and other proprietary hardware, which would lock OCMI into using one company\u2019s products. Site Scan, however, is compatible with a range of drone technology. Recently, when one of his organization\u2019s drones required maintenance, Dorsey was able to continue flying weekly missions using his personal drone.\r\n\r\nDorsey was also able to learn how to use Site Scan quickly and easily because it is user-friendly and intuitive. After receiving airspace authorization at the project site, Dorsey began flying his drone every Thursday to take images of the construction.\r\n\r\n\u201cI went out, and I took my drone out and flew it, and I tried to reverse engineer how I thought the software would work,\u201d Dorsey said. \u201cThe datasets were pretty large\u2014about 700 to 900 photos per mission.\u201d\r\n\r\nFor the stadium construction project, which began in 2020, Dorsey said his typical workflow was to fly over the site with a drone, upload the images to Site Scan, and then process the imagery. He shared a weekly distribution report with stakeholders that showed the site plan and included a link to a 2D orthomosaic and a 3D mesh model that let users walk around the site remotely. Dorsey also included videos from his flights."},{"acf_fc_layout":"image","image":580102,"image_position":"left","orientation":"horizontal","hyperlink":""},{"acf_fc_layout":"content","content":"

Capturing the Right Metrics<\/h2>\r\nBecause site construction began at the height of the COVID-19 pandemic, using Site Scan was key for Dorsey and his team to keep stakeholders up-to-date on the project.\r\n\r\n\u201cI [would] get requests from clients [that said], \u2018Hey, can I get that new plan? [\u2026] It created a sense of awareness of [the] project site from a visual aspect,\u201d Dorsey said. \u201cPeople do like the 3D mesh model. That does give them visibility on the project site.\u201d\r\n\r\nDorsey was pleased that Site Scan gave him the ability to create models. He and his team recently used the software to complete a topographic survey of the new women\u2019s lacrosse field at San Diego State University. Using ground control points of the field, he said he completed a drone flight in 15\u201320 minutes and was able to immediately process the data to create the survey. Getting a plane or helicopter to fly the same mission could cost $8,000 to $10,000, so the use of a drone and Site Scan led to significant cost savings.\r\n\r\n\u201cBack when I was flying a drone as a photographer, I was just taking artistic photos or getting to spots that I wanted to capture. But you couldn\u2019t create models,\u201d Dorsey said. \u201cSo I see the value of how this is going to start to weed out some of those big-dollar costs on projects if you have the right tools in place to do so.\u201d\r\n\r\nOn the Snapdragon Stadium construction project, using Site Scan enabled OCMI team members to obtain the metrics they needed for their client. When the original stadium was being taken down, construction personnel created large stockpiles of concrete, and an on-site batching plant was set up to reprocess it. OCMI was asked to get quantity takeoffs on the stockpiles\u2014that is, to estimate materials\u2014and Dorsey and his team were able to use Site Scan to run volume calculations that told grading subcontractors exactly how much material was excavated."},{"acf_fc_layout":"image","image":580112,"image_position":"right","orientation":"horizontal","hyperlink":""},{"acf_fc_layout":"content","content":"\u201cWhen we were faced with a change order request, we were able to quantify exactly how much material was in the various three stockpiles on-site, which then we were able to [use to] thwart the claim that there wasn\u2019t enough material to fulfill the base [of the stadium],\u201d Dorsey said. \u201cSo that was a big win for having [Site Scan].\u201d\r\n

Knowledge Sharing for Continued Returns<\/h2>\r\nDespite the challenges of constructing a new stadium with recycled materials during a global pandemic, Snapdragon Stadium was built on time and came in under budget.\r\n\r\nThe successful deployment of Site Scan for the stadium project has led Dorsey and the OCMI team to use it for other construction projects as well. And Dorsey\u2019s end goal is to pass on the knowledge he\u2019s gained and teach other pilots how to employ the technology.\r\n\r\n\u201cI\u2019m thinking, how do I scale it?\u201d Dorsey mused. \u201cIt\u2019s just something that I\u2019m really passionate about and want to invest in. I think there are a lot of returns when it comes to where [Site Scan] is going.\u201d"}],"references":null},"yoast_head":"\nFor New Stadium Build, Drone Technology Keeps Sustainability On Track | Spring 2023 | ArcNews<\/title>\n<meta name=\"description\" content=\"The project involved recycling concrete from an old stadium to use at the new venue.
