Using Drones in Construction for Aerial Inspection, Photogrammetry or Lidar

Drones are creating new workflows, processes and applications in construction design, surveying and mapping, and many see them as the future of the construction industry. Rick Rayhel, Microdrones' sales manager for United States' Western Region, is one of those people; he's seen first hand how drones can enhance the construction business. In the U.S., drones have only been used to aid construction in the last couple of years. On the precipice of drone potential, Rayhel said, “There’s never a lack of ideas or interest on what can be done with drones.” Perhaps the biggest advantage of drones in construction, though,...

3D Modelling for Construction

When it comes to 3D modelling for construction, what are the advantages and disadvantages of photogrammetry versus Lidar in terms of accuracy, complexity and cost? Breaking away from laser measurement in construction is a taboo subject, perhaps hampering the use of photogrammetry. In construction, aerial survey has enormous time-saving benefits for measuring groundwork areas. Data can be used for asset classification, construction validation as well as health and safety. In particular, regular scans provide a time series of work in progress to detect new issues, managing risk rather than responding to it. This article looks at the state of the... (read more)

Virtual Design and Construction to Plan, Build and Manage Every Project

As a US-industry leader in the application of Virtual Design and Construction (VDC) technologies, Hensel Phelps continues to advance the use of VDC to improve the process of design and construction projects. It does so from beginning to end, through the implementation of technologies such as 360 photogrammetry plans, integrating drone use into safety plans, and applying drones to verify topographic design. This article provides an in-depth look into how Hensel Phelps utilizes these three up-and-coming technologies throughout construction sites. At the ongoing US$225 million McGregor Square project located in Denver, Colorado, Hensel Phelps is using 360 cameras to document... (read more)

The Smartphone as a Professional Mapping Tool

To what extent will the smartphone become a professional mapping tool? Modern smartphones already contain many of the important functions to be used as mapping tools. However, whether they are suitable for use as such professionally depends not only on the built-in sensors, but also on the available computing power, RAM and data storage capacity. For data acquisition, a smartphone usually has two to three cameras, a GNSS sensor, an acceleration sensor and a gyroscope for positioning the system in 3D space. In addition, a smartphone has a magnetometer which displays the orientation or north direction by a compass, and... (read more)

Taking Full Advantage of the Benefits of UAS Technology

Leveraging UAS technology across surveying and engineering sectors is demanding. Meeting the expectations of accuracy and accountability requires the best in expertise, methodology and equipment. The latest unmanned aerial system (UAS) photogrammetric hardware and software now enables surveyors to capture millions of survey measurements on the ground, where they would previously have measured only hundreds. It is essential to have the best-quality equipment, software and workflows to ensure this data is accurate, robust and defensible for professional use. Geosyntec is a leading consulting and engineering firm that works with private and public sector clients to address new ventures and complex... (read more)

Rebuild Ready: 3D Mapping a Quake-damaged Cathedral

Surveying a damaged building can be dangerous. Mapping using drones reduces risk to staff and costs to the community. This case study on the iconic cathedral of Christchurch, New Zealand, severely hit by an earthquake, demonstrates how drones and advanced photogrammetry software delivered the orthomosaic map enabling the accurate spatial planning needed in order to rebuild the cathedral. In February 2011, New Zealand’s second-most populous city was rocked by an earthquake. The iconic Christchurch Cathedral was shattered in the shake, and the clean-up is still ongoing. Christchurch's central city and eastern suburbs were badly affected. Before the cathedral can be rebuilt and the... (read more)
