Using drones in the construction industry

By Pae Natwilai -  12/24/2018

People have been building things for a long time – that’s for sure. Construction has been around for centuries, and it should be round for many more. However, construction today isn’t the same as it was a thousand years ago. As with anything, things modernise and develop. Today, things are moving faster than ever, and new ideas, methods and technologies are entering the construction industry every year.

건설현장 드론 활용 어디까지 왔나

[미래의 드론 활용 기술]

측량 3차원 데이터 실시간 전송

자동으로 작업량 시공계획 산출

관제센터 지시로 건설장비 작업 수행

  드론을 통해 건설현장을 측량한 3차원 데이터가 실시간으로 서버에 전송되고, 이를 바탕으로 자동으로 작업량과 시공계획이 산출된다. 이 데이터는 현장의 건설장비로 전송되고, 관제센터의 지시에 따라 건설장비는 작업을 수행한다. 현장 근로자는 지형정보와 작업 진척상황 등 최신정보를 수시로 받을 수 있어 최적의 공사계획을 세울 수 있으며, 현장의 문제와 변화에 실시간으로 대응할 수 있게 된다. 조만간 국내와 한국 건설사가 진출한 세계 각지의 건설현장에서 목격하게 될 일상의 모습이다. 국내 주요 건설사와 건설 공기업이 4차 산업혁명시대의 대표 상품인 드론을 활용한 측량, 공정관리 등에 속도를 내고 있기 때문이다.

업계에 따르면 국내 대형 건설사 대부분은 이미 드론과 빅데이터, 정보통신기술(ICT) 등의 현장 적용과 고도화를 위한 별도 조직을 신설·운용 중이다. 대우건설의 경우가 대표적이다. 대우건설은 ‘대우 스마트 건설’(DSC) 시스템을 활용해 실시간 관제, 안전 환경 모니터링 등의 작업을 수행 중이다. 특히 대우건설은 사람이 직접 하기 어려운 대단위 면적의 산업단지 현장이나 방조제, 매립지 등의 토사량·매립량 측정 등에 드론을 적극 활용한다. 드론이 촬영한 사진은 3차원(3D) 입체 방식으로 제작돼 보다 정확한 현장정보를 산출할 수 있다. 대우건설은 2017년부터 전국 40개 건설공사 현장에서 드론을 활용해 왔다. 전문 업체와 협력을 통해 장시간 비행 가능한 드론도 개발 중이다.

중견업체 가운데선 한라가 최근 드론을 활용한 ‘드론 가상현실(VR) 촬영 공정관리’, ‘드론측량 3차원(3D) 현장관리’, ‘모바일검측앱’을 건설현장에 시범도입해 관심을 끌었다. 한라는 국토교통부, 기획재정부, 한국토지주택공사(LH)가 공동 주관한 ‘드론웍스데이’에 건설사로는 유일하게 초청을 받아 관련 기술력을 인정받았다. 한라의 드론 VR 촬영 공정관리는 현장 상공에서 드론으로 360도 파노라마 촬영을 하고, 촬영정보를 공유해 관리하는 기술이다. 드론측량 3D 현장관리는 드론으로 항공사진을 촬영한 후 프로그램을 이용해 현장 현황을 3D로 모델링한다.

5세대(G) 이동통신시대를 앞두고 통신사와 건설사의 협업도 강화되고 있다. 현대중공업그룹의 현대건설기계는 최근 SKT, 측량 전문기업 미국 트림블사와 ‘스마트 컨스트럭션’ 사업협력에 관한 양해각서(MOU)를 체결했다. 현대건설기계의 스마트 컨스트럭션은 측량부터 시공, 완공 후 유지관리에 이르기까지 토목공사의 프로세스 전반에 걸쳐 ICT를 활용해 관련 정보를 취합·분석·제어하는 지능화 기술이다. 또 SKT는 5G 통신을 포함한 통신서비스 제공 및 건설현장 안전을 위한 다양한 솔루션 개발을, 트림블은 드론을 이용한 지형 측량과 변환 솔루션 개발 등을 담당한다.

That’s why drones have started to make such a big impact. While they aren’t helping the actual labour process (yet) – they’ve still got a huge role to play in the construction industry, and that role is growing. Drones have helped revolutionalize the planning stages of construction, along with land surveying and data capturing. And these are just a few of the uses for drones in construction.

Construction is one industry that’s really taken drones and run with them. Drone use in construction is up year-on-year, and that looks et to continue. There are two simple reasons why drones are so popular in construction – they can save developers time and money. Builders love drones because they can provide an aerial view of either sites or potential sites with simple and affordable ease.

Previously, you had to pay for a manned aircraft to get such an aerial view. The cost of doing that can be prohibitive to many building firms, especially smaller ones. Even those that could afford to do it, wouldn’t do it regularly.

Now with drones, you can get up-to-date images as often as you like. Every day if you need them. That means you can get a real feel for how the build is progressing. Drones allow builders the chance to develop better plans, track progress and monitor any issues with the construction by providing an unrivalled wide-view of a site at a fraction of the cost.

Key benefits of using drones in construction

Mapping a site

Creating maps of construction sites used to be difficult and labour-intensive. That also made it expensive. Hiring a plane obviously isn’t cheap, and that often meant only large building firms could afford to do it for big projects. Now, a drone can access any area of the site you want with relative ease, while capturing all the information and footage and relaying it in real-time to computer mapping software.

Inspecting construction sites

Most construction sites need regular checks and inspections – but this can be dangerous work. Now drones can carry out real-time inspections of high risk areas so you don’t have to send people to them. This helps improve health and safety on a site, which should be a construction firms’ biggest priority.

Images can be relayed back to an advanced modular ground control system, allowing health and safety managers the chance to inspect a site without leaving their office.

Building surveys

Building surveys are another area where drones have really helped. Checking something like a roof used to be difficult, expensive and dangerous. Especially if it’s a particularly difficult roof to access. Now you can simply fly a drone up there and analyse live video in real time. That means you don’t have to spend time and money on scaffolding and ladders. Inspecting roofs like this also help improve health and safety on site dramatically.Building surveys that use drones are much faster, safer and cheaper.

Disadvantages of using drones in construction

While drones have tons of benefits in the construction industry, there are a few key points you need to be aware of. Let’s have a look at them:

Firstly, you generally need two people operating a commercial drone at the same time. It’s not a one-man job, and these people need to be highly trained in drone use while being fully aware of the planned flight path and any other relevant issues.

Those operating your drones will need to have plenty of experience doing so in the construction industry, and have specific knowledge of the exact model of drone they’re in control of.

You also need to be fully aware of any weather issues that could prevent the drone‘s safe or effective use. Cloud and wind are the two most common problems for many commercial drones. Too much wind could make the drone impossible (or unsafe) to fly, and too much cloud cover could prevent the right images being taken.

Drones are also expensive. While they should save many construction firms a lot of money in the long-run, they have a high up-front cost. This should hopefully come down in the next few years as the technology becomes more common.

Drone use in the construction industry has seen massive growth in recent years, and this looks set to continue. With technology improving for drones every year, they look set to help construction even more over the next decade.
