Case study: ADA Compliance

ADA standards state that, “Among other things, the Americans with Disabilities Act (ADA) ensures access to the built environment for people with disabilities. The ADA Standards establish design requirements for the construction and alteration of facilities subject to the law. These enforceable standards apply to places of public accommodation, commercial facilities, and state and local government facilities.” Continue reading “High-Accuracy 3D Laser Scanning Helps Illustrate Critical Measurements”

Easier Airspace Authorizations on the Horizon for Commercial Drone Pilots

Jon W. Adams, Director of Architectural and Heritage Services ::::
The Federal Aviation Administration (FAA) is hard at work on developing the Unmanned Traffic Management System (UTM), a “traffic management ecosystem” that will “ultimately identify services, roles/responsibilities, information architecture, data exchange protocols, software functions, infrastructure, and performance requirements for enabling the management of low-altitude uncontrolled Unmanned Aircraft System (UAS) operations”.
The first step of this process has been centered on the Low Altitude Authorization and Notification Capability (LAANC), a system by which Part 107 (commercial) pilots will be able to obtain airspace authorizations in controlled airspace much more efficiently than the current system, which requires an online form to be filled out, followed by a waiting period of up to 90 days.
For many Part 107 pilots, including DJS pilots, this 90-day barrier has meant that some projects that could benefit from aerial stills and video could not be accomplished in a timely manner. Continue reading “Easier Airspace Authorizations on the Horizon for Commercial Drone Pilots”

Preparing for the next generation (AR/VR)

Jon W. Adams, is the Director of Architectural and Heritage Services ::::
DJS Associates strives to stay on the forefront of technology, both in how we collect our data, and how we present the results to our clients.
DJS Associates continues to research various new and exciting ways in which we can demonstrate the results of engineering analysis and documentation efforts. As we look to the future, we observe that technology continues to develop rapidly, with each generation possessing increased knowledge on how to interact with complex gadgets. Of particular interest are gadgets that allow for interactions with data, within our “reality”. Below are two of the “reality” technologies DJS Associates is exploring.
Augmented reality (AR) is a technology in which real-world environments/objects are augmented by computer-generated sensory input such as sound, video, graphics or GPS data.1 With this technology, users can point their “smart “ electronic devices at real-world objects, and interact with virtual data in the real-world.
AR can possibly be used by engineers in the field, overlaying information captured on the day of an incident. AR has the potential to aid in understanding the events which led up to the incident.
In the AEC world, AR can be utilized to help stakeholders envision a new design over existing features/structures.
Historical objects/structures can be seen alongside current day conditions, adding to the interactivity of visitor tours. Continue reading “Preparing for the next generation (AR/VR)”

Drone Alphabet Soup: Decoding Drones

Drone Documentation

Jon W. Adams, Director of Architectural and Heritage Services ::::
FAA. NAS. UAS. PIC. VO. 14 CFR Part 107. Confused? You may be… unless you’ve been dabbling in drone flight, and the associated regulations which govern the use of drones.
Below, I will briefly cover a few of these items, which I hope will help in learning more about drones and how they operate in the airspace above the United States.
FAA – Federal Aviation Administration
This is the national authority which regulates all aspects of civil aviation, including air traffic control, certification of personnel and aircraft, and others.
NAS – National Airspace System
The airspace above the Unites States, which is broken down into specific classes: A, B, C, D, E, and G. Legal drone flight is only permitted in class G airspace, unless special permission is granted by the FAA. Continue reading “Drone Alphabet Soup: Decoding Drones”

Part Two: What’s In Our (Data Collection) Toolbox?

In case you missed it, click Here to read PART 1 of What’s In Our (Data Collection) Toolbox?
Jon W. Adams, Director of Architectural and Heritage Services ::::
DJS Associates utilizes a number of different tools to collect important data. Whether we are working on a forensic case, capturing as-built measurements for AEC documentation, or digitally preserving important historic landmarks, it is always important to have the right tool for the job. We previously discussed our use of DSLR cameras, video recording systems, and Unmanned Aerial Systems (UASs). Here, we will look at our use of 3D laser scanning technology, and some of our laser scanners. Continue reading “Part Two: What’s In Our (Data Collection) Toolbox?”

Part One: What’s In Our (Data Collection) Toolbox?

Jon W. Adams, Director of Architectural and Heritage Services ::::
At DJS, we utilize a number of different tools to collect important data. Whether we are working on a forensic case, capturing as-built measurements for AEC documentation, or digitally preserving important historic landmarks, it is always important to have the right tool for the job.

DSLR cameras/video recording systems

Although DSLR (digital single-lens reflex) cameras and video recording systems are common items utilized by millions of consumers in their everyday lives, they are still essential tools in every DJS case/project.
Video recording systems are utilized to analyze signal timing patterns at intersections of interest, and also to provide a visual record of inspection procedures.
DSLR cameras are used by DJS technicians to capture photographs during accident site investigations/vehicle inspections, providing additional context for measurement data that is captured, and also supplementing details relating to conditions present at the time of the inspection.

Industry Update: UAS Part 107 – New Rules Are in Effect!

Drone Technology

Jon W. Adams, Director of Architectural & Heritage Services ::::
On August 29th, 2016 the small UAS Rule (Part 107) went into effect. This rule will have a major impact on how Unmanned Aerial Systems (UAS) operate commercially in the National Airspace System over the United States.
Prior to this rule, the only way to legally operate a UAS, for commercial purposes, was to apply for and receive a Part 333 Exemption, which was an arduous task. Process aside, the 333 Exemption also required that operators hold “either an airline transport, commercial, private, recreational, or sport pilot certificate”…in other words, a license to fly a manned aircraft.
