Projection Mapping by International Artists in Napa, CA

By | Uncategorized | No Comments

Napa Lighted Arts Festival 2020 welcomed international artists to create 3-dimensional light shows projected onto some of Napa’s iconic buildings throughout downtown. 3DVDT helped make this possible by capturing the building facades with 3D laser scanning and photogrammetry to create 3D models for the artists to use as templates, allowing them to create their shows virtually.

3D Projection Mapping onto Building Facade for 150th Anniversary

Producing an amazing 3D projection mapping show onto a building facade requires a 3D model. 3DVDT scanned the building facade using a 3D laser scanner, then created a precise 3D model from the scan data to be used as a template for the artist to realize the show.

The Magic Lantern 3D show was created for the 150th Anniversary of Redwood City.

Oakland’s Brooklyn Basin 9th Ave. Terminal to be Preserved

By | Uncategorized | No Comments


As development of Oakland’s largest new building development in a half a century is underway, efforts to save the historic 9th Avenue Terminal at the Port of Oakland have resulted in the preservation of the historically significant portion of the building, to showcase a maritime museum.

3DVDT surveyed the 180,000 sq. ft. warehouse that was opened in 1930 at the west end of Brooklyn Basin. The survey was executed using 3D laser scanning technology to create a 3D model and 2D CAD drawings.

The main purpose of the warehouse building was to handle lumber, steel and other bulk commodities. It is the last surviving municipal terminal in Oakland constructed from the 1925 voter-approved harbor bond, and has been in continual use from October 1930 to 2015. It is a rare example of a particular architectural typology; a prewar municipal port building utilized for break-bulk cargo in Oakland with railroad spur tracks on either side, and extensive open platform space along the west side.

An Important Message From An Industry Expert

A recent article published in LiDAR Magazine by a colleague speaks the truth about the benefits of 3D laser scanning technology in the construction industry.

“I find it inexcusable for any significant new construction project to not incorporate 3D laser scanning technology as a part of the QA/QC construction process on a phased approach or milestone basis. There is simply too much to be gained by utilizing this technology. It shows the lack of understanding or maybe unwillingness to change within the construction industry. The small amount of investment in this process can literally have 10x ROI or even more.”  Ken Schmerz, Eco3D

Precision Preservation at Mare Island with 3DVDT

By | Uncategorized | No Comments

2015-11-06 09.11.36On November 4th, on-site documentation took place in the form of several workshops, sponsored by California Preservation Foundation in partnership with Mare Island Historic Park, Vallejo CA.

Demonstrations of laser scanning, photogrammetry, drones and large format cameras engaged a curious audience eager to learn more about innovative technologies currently used to assess, evaluate and measure historic properties and landscapes.

Mare Island, site of the U.S. Navy’s first permanent base on the West Coast, has several hundred structures and sites of historic and architectural interest. The shipyard opened in 1854 and had the first permanent drydock, turning out ships from WWI & WWII in its 142-year history.

3DVDT performed a live demonstration of laser scanning the facade of Building 46.  Built in 1855 and once the Pipe Shop/Smithery, it is an example of industrial Romanesque Revival architecture.  A presentation by Shari Kamimori followed, explaining the post-processing registration of the scan data and included case studies focused on post South Napa Earthquake analysis of several historic structures damaged by the Earthquake.

Scan to BIM Solution For Off Site Fabrication

Pre-Fabrication of a Containment Structure for the historic Goodman Library

Designed by local Napa architect Luther Turton and constructed in 1901, the Goodman Library suffered extensive damage from the South Napa Earthquake in August of 2014.

The tower stands currently at risk of further damage due to potential after shocks and vibrations from a development project under construction directly adjacent to the building. The imminent danger of falling masonry presents a potential hazard to passers by down below.

The immediate concerns of City officials to shore-up the tower presented several challenges to the project architect and engineer.  Ultimately, the ideal solution would be to design and construct a containment structure off site whereby the contact of contractors on the fragile roof structure was minimal.

The solution: Laser scanning is an effective, non-invasive method to document buildings too fragile or structurally unsound for direct contact.

3DVDT was commissioned to laser scan the building and produce a 3D model. The scan data was used to accurately measure the tower virtually which enabled the architects to design the containment structure without physical contact to the building or rooftop.

The containment structure will be pre-fabricated off site and hoisted by a crane over the tower where it will be secured.  Minimal roof contact will be necessary by a single contractor to anchor the containment structure to the roof.



Should I Stay or Should I Go? From the US to the UK

With today’s technology, it is pretty cool to be able to communicate with a collaborative partner “virtually”, however, there may come a time when “face-to-face” contact becomes necessary in order to grow the relationship. So I asked myself, “should I stay or should I go?” The answer was clear, and a recent trip to Worcester, England proved to be a trip worthwhile.

The initial contact was established through Linkedin and the communication via emails. We then progressed to virtual Skype conversations, which led to a collaborative working relationship between the two companies.

The convenience of remote access to data and communication, allowed us to effectively deliver the project until the project size began to grow. The overseas time difference, combined with traditional ‘snail mail’ (data too large to send via internet) posed unforeseeable problems to meet the deadlines.

So off I went to Bury Associates, Ltd. in Worcester, England to learn about their in-house workflow, speak with their managing staff, and most importantly to build trust and rapport for enhancing the partnership.

There is no doubt that electronic communication is valuable and cost-efficient for initiating contact and establishing rapport, but when things get more serious, it’s time to make a trip in person!
