St. Nicholas Church at 155 Cedar Street in New York City was the only place of worship destroyed in the September 11, 2001 attacks.
Today, Skanska, a multinational construction and development company, is responsible for new project of the church. Among them, NavVis VLX wearable scanning system is used to provide accurate construction archives to support site space planning.
According to Val Tzvetkov, Skanska's senior regional VDC (Virtual Design and Construction) manager, technicians using NavVis VLX can capture the entire floor plan in less than an hour, including low ceilings and narrow passages.
"A variety of poses unlock different terrains, and there is nothing NavVis VLX cannot go."
"To build a building, timely and accurate archiving is essential to support spatial planning." Tzvetkov explained. "NavVis VLX scans complex terrain including corners and crevices in less than 60 minutes."
When completed, the new St. Nicholas Greek Orthodox Church at 130 Liberty Street and the National Shrine will serve as places for believers to pray and reflect silently.
The new building was designed by Spanish architect Santiago Calatrava and is modeled on the Byzantine churches of Hagia Sophia and the Church of the Holy Savior in Istanbul. Designers hope that this building can light up the darkness at night and become a beacon of hope for the World Trade Center.
In addition, NavVis VLX also helps Skanska overcome scanning difficulties and easily generate archive point clouds.
"SLAM captures space 90 percent faster than traditional ground-based laser scanners." Using NavVis VLX to record the construction process of the new St. Nicholas Church and Shrine is more efficient and smooth than traditional scanning equipment.
Tzvetkov said: "Faster and more accessible data can help decision makers make effective decisions in a short time. "Good mobile scanning will greatly reduce the time required for field scanning and post-processing of data in the office. He added: "It would take several days to do the same thing with a ground-based laser scanner."
NavVis VLX
Mobile scanning equipment that is 90% faster than fixed-point laser scanning.
NavVis VLX is the first choice for disruptive scanning technology, providing high-precision compact and multifunctional scanning equipment for professionals in AEC (Architectural Engineering And Construction) departments. NavVis VLX relies on SLAM (simultaneous localization and mapping) algorithm ,which can easily build the surrounding environment by walking slowly.
