Beschreibung

A start-to-finish roadmap on incorporating drone technology into your AEC firm workflow Drone Technology in Architecture, Engineering and Construction: A Strategic Guide to Unmanned Aerial Vehicle Operation and Implementation is the only process-driven, step-by-step handbook to implement drone technology in AEC workflows. It provides a comprehensive and practical roadmap for architecture, engineering, and construction firms to incorporate drones into their design and construction processes. The book offers extensive information on drone data processing, and includes guidance on how to acquire, manipulate and use the various data types produced from drone flights. The creation of three-dimensional data and visualizations are covered in-depth. Drone Technology reviews how to select and fly drones based on data needs and initial costs, and how to collect and maintain required flight logs, licenses, and permits. Drone Technology uses several real-world project examples that demonstrate and explain how drones can be used to collect: · Full-color orthorectified imagery · Accurate 3D point cloud and mesh models · Topographic contours · Digital Elevation Models (DEMs) The project examples also describe how these datasets can be integrated with 3D models of proposed conditions, photos, and other project datasets. Drone Technology in Architecture, Engineering and Construction is an essential guide for a wide variety of professionals, from civil engineers to landscape architects. It provides information on professional use of drones for those just considering the technology, to those already flying drones professionally. It is an invaluable guide for anyone working in the design or construction of buildings and landscapes.

Acknowledgments

Jon Altschuld

This book has been created at a crossroads in my life. Shortly after deciding to go out on my own and found Chinook Landscape Architecture, my longtime friend and colleague Daniel Tal approached me about co-authoring a book on drone use and technology. We had collaborated on projects for many years and had even written a business plan for integrating drones into an existing practice when we worked together at a global engineering firm. The idea to write this book was exciting and intimidating, much like the idea of going out on my own. And, as was the case with starting Chinook, there are many friends, colleagues, and family members who made it a possibility.

Thank you to Daniel for always being a collaborative resource and for co-authoring this book with me.

There were several drone industry professionals who were helpful, and I'd like to give a special thanks to Eran Steiner, founder and CEO of AirData UAV, and Joshua Haga of Pix4D. Eran reviewed and added to sections outlining the importance of maintenance and operations logging, and Joshua was a tremendous help in analyzing photogrammetry data and metrics for particularly complex subjects.

Many of the projects highlighted in this book were collaborative efforts. Howard Hume of Yeh and Associates, Inc. and Kevin Shanks of THK Associates, Inc. were key members of several of these projects.

And finally, a big thank you to my wife Brittany and our entire family for putting up with late nights, weekend work, and the overall level of stress that comes with both starting a company and writing a book.

Daniel Tal

There are many people I would like to acknowledge that led to the creation of this book.

My parents, Nissim and Ruth Tal.

Justin Clark, who might as well be an uncredited author for this book. A partner in work and innovation, our synergy and combined energy moves mountains, crashes drones, fries computers and made this book possible. I've never met or worked with a more talented person who I also call friend.

Jenn Becker, Kaitlin Weber, Christ Fortin, Sam Carpenter and Alex Kistler for their boundless humor, dedications to their craft, and making the days fun even when work is not.

The support of my wife, Jenn, and two kids, Anina and Raya, who are the reasons I do anything in my life, I do it for them.

Ann Christensen, Bill Neumann and Laura Kirk, Karen Current, and last but for sure not least Mark Wilcox for their support and belief in the work we do.

DHM Design who has funded my drone work and training; none of this would be possible without them.

PART 1Introduction to Drone Practice

CHAPTER 1How to Use This Book

This chapter will provide an overview and road map of the book's content to allow readers to have a clear understanding of how to approach the book's information.

Drones for Architecture, Engineering, and Construction (AEC)

Welcome to Drone Technology in Architecture, Engineering, and Construction. This book will delve into the world of drones and how to implement and achieve professional quality results using a drone in a variety of AEC related industries.

First, it is important to define the word drone as it relates to this book. The word drone is used throughout this book to describe the various flying devices used to collect video footage, images, and other data. Two more technically correct terms for these devices are UAVs (unmanned aerial vehicles) or UASs (unmanned aerial systems). All three terms will be used throughout the book.

The primary focus of these chapters is how to implement and use drones as it relates to architecture, engineering, and construction (collectively called AEC) projects. The book is a road map to implement UAVs through process driven steps with an emphasis on AEC projects. As detailed in the parts and chapters below, the book will review specific technology, software, regulations, costs, and practical data, and will provide direction to the implementation and management of drones with an office business cycle and budget.

While detailed, the book is by no means comprehensive, as the technology is changing and updating at a fast pace. However, this book should be more than enough to get any reader started with flying a drone, getting insured/licensed, and collecting basic site and project data (Figure 1.1).

The Method Behind This Book

Process is at the heart of this book. With that in mind, readers should go sequentially through the chapters, even if they are already familiar with some of the material. In that case, skim through sections, but it is important to understand all the different levels of logistics involved with using drones for work.

Who Can Use This Book?

This book is intended for anyone interested in using drones, particularly on a professional level. This includes hobbyists, architects, landscape architects, surveyors, engineers, planners, and anyone else working in exterior built and non-built environments.

This book DOES NOT require any prior knowledge or use of a drone. Instead, readers will be provided with the full spectrum of requirements and activities to implement the tools, buy the drone hardware, work with specific software, and understand regulations, permitting, and rules that govern UAVs.

The license and permitting portions of the book focus on the rules in the United States, but the remainder of the content would be appropriate for drone pilots and users anywhere in the world.

The Book Road Map

Part 1: Introduction to Drone Practice serves as a general introduction to drones and provides an overview for the book. In addition, Part 1 provides a big picture approach to how drones fit within a firm, what they can accomplish, and why the technology is easy to implement, if not required. Part 1 includes:

Chapter 1: How to Use This Book provides a quick guide and overview for readers on how to best approach this book. Chapter 2: A Paradigm Shift in Viewing the World discusses the ethics, design implications, and mindset that drone operators and managers should consider when bringing these tools to practice. Chapter 3: Drone Data Visualization as a Full Cycle Tool reviews specific project types that have used drones. These projects span the broad AEC industry and demonstrate how UAVs can be adapted for many types of locations, project goals, and the range of deliverables (Figure 1.2).

Part 2: Getting off the Ground provides the nuts and bolts of drone ownership, implementation, permitting, and start-up costs. It includes chapters on how to fly a drone, a review of drone hardware, specifics about rules and regulations, and tips to get the best results for specific projects. Chapter 4: Buy In, addresses the challenge of bringing a new technology to a practice. This includes how to answer questions from stakeholders about implementing drones easily, and with minimal investment and full understanding of the benefits. Chapter 5: Getting Started delves into drone hardware, what drones are best to start out with, the types of drone sensors and equipment, computer hardware requirements to process drone data, and photogrammetry and applications and software. Chapter 6: Documentation, Permissions, and License focuses on the drone pilot requirements to legally fly a drone in the US, as well as ethical and insurance considerations. This includes how to obtain permission from clients and locations to fly, access important flight data, and how best to approach liability issues. Chapter 7: Best Practices for Flying delves into the specifics of actual drone flight. This will include how to best start flying a drone to collect videos, still images and specific data, and review autonomous drone flight through the use of apps (Figure 1.3).

Part 3: Acquiring and Working with Drone Data focuses on drone data types and processing. This includes how to acquire, manipulate, and use the various data types produced from drone flights. Chapters provide details on converting photogrammetry data into useful 3D models. Chapter 8: Imagery and Videos provides examples of different types of graphics, videos, still images, and diagrams that can be derived from drone footage. Chapter 9
