Virtual Design Analysis Group is a division of NVentum, LLC.

This unique collaborative endeavor; to utilize the latest reality capture technology to document the artifacts, buildings and campus of History San Jose, provides opportunities for private sector, non-profits and institutions of higher education to work together to solve some of today's most pressing engineering issues. The protocol for retrofitting as-built historic facilities and the use of new technologies to preserve our most prized historic treasures are vital to the continued success and expanded influence of our museums.
This blog will document the challenges and successes of this ambitious, one of a kind project.

Laser Scanning's Impact On Surveying

How Laser Scanning Has Revolutionized Surveying
Laser scanning provides more detailed and more accurate data than information obtained through manual measurements, incomplete or obsolete as-built drawings and/or maps.

The accuracy of models prepared using laser scanning technology translates directly into reduced project cost due to the reduction of construction reworks and delays. 3D models also facilitate cost reduction through the accurate development of prefabricated construction components and materials.

Prevents schedule delays by reducing time required to collect data from as-built structures 

Safer data collection- information can be obtained from the ground without the need for harnesses and other safety equipment. Data can be collected in areas that are too dangerous or unstable for people to safely work

Unobtrusive data collection technology reduces field construction time and facility down time.

Data captured by the laser scan can be translated in accurate 2D or 3D AutoCAD drawings to be used for 3D visual walk-throughs and 2D or 3D design. The data could ultimately be rendered into a complete 3D Building Information Model. 

How Laser Scanning Is Revolutionizing Museums and Public Venues
The 3D Model is the ideal database for storing and accessing information about the entire life-cycle of a facility.

Building Information Modeling contains building geometry, spatial relationships, geographic information, quantities and properties of building components and materials.

Data contained in the BIM allows for real-time energy audits, acoustical simulations, maintenance and monitoring of air contaminants/pollutants and development and implementation of various RFI technologies and solutions.

The marriage of BIM and GIS technology will provide unique marketing/sales opportunities resulting in new revenue streams for facility owner/operators.

The concept of Virtual Museums is no longer confined to a collection of high definition photographs.

3D model is an excellent marketing tool; allowing a client, exhibitor, guest or visitor to see the facility without actually being there.

BIM is a useful tool in the reduction, monitoring and maintenance of a facility's carbon footprint.

BIM software applications allow building operators to monitor and adjust the building's electrical, environmental, mechanical and security systems remotely via SMART phones, tablets or laptops.
