Digital twin of an object: what is it and why does a developer need it?
A digital twin in construction is an interactive 3D model of a real object, created from laser scanning and photogrammetry, in which you can move, measure distances and see structures with millimeter precision. Essentially, this is a “cast” of the building at a specific point in time, accessible through a browser from any device. The technology came to construction from industrial IoT and over the past five years has become a working tool for developers, general contractors and technical supervision. Below we will look at what problems a digital twin solves, how the shooting goes and how much it costs.
Why does a developer need a 3D tour of the property?
A digital twin solves several developer pain points at once - from sales to work acceptance. Specific benefits:
- Remote sales of apartments and commerce. The buyer walks through the actual layout from anywhere in the world. According to our client developers, the conversion into a deal from a 3D tour is 25–40% higher than from a regular photo gallery, and the number of “idle” impressions drops by 2–3 times.
- Recording hidden work. One pass with a scanner - and you have an archive of all utilities before covering with plasterboard. After 2 years, when renovating, you don’t need to break down the wall to find the riser.
- Construction control by stages. The weekly scan shows actual progress and discrepancies with the schedule. Technical supervision and the customer see the same picture without visiting the site - saving up to 8 hours per week per engineer.
- Reception and claims work. Accurate measurements directly during the tour record deviations from the project. The dispute with the contractor about “how it was delivered” is closed with one screenshot with the date.
- Marketing and investor presentations. The finished object is shown to the investor in 5 minutes instead of a two-hour visit. The tour is embedded on the website of the residential complex, in Avito, and in commercial rental offers.
How is a digital twin of a construction site created?
The process takes from one day for an apartment to a week for a residential complex. The stages are standardized:
- Departure of an operator with a Matterport Pro3 or Leica BLK360 scanner. The equipment makes 360° panoramas and a point cloud every 2–3 meters. Apartment 80 m² - about 1.5 hours of work, business center floor 1500 m² - one working day.
- Data processing. The point cloud is collected into a single model, marks, measurements, a floor diagram are added, and, if necessary, a connection with the BIM model in IFC format.
- Tour accommodation. The finished digital double is available via this link 24–72 hours after shooting.
We offer three options for storing and delivering a tour: 360° Space cloud with high-speed servers and technical support; deployment on the customer's server - if security requirements prohibit external hosting; offline version for PC or a separate assembly for the Meta Quest or Pico VR headset - works without the Internet at exhibition stands and private presentations.
The finished model opens in any browser, does not require plugins, supports sharing via a link with access rights, and is integrated into the developer’s CRM via API.
How much does a digital twin of an object cost?
The price depends on the area, complexity of the geometry and accuracy requirements. Market guidelines:
- Apartment 40–100 m² — from 8,000 to 18,000 rubles for a ready-made tour with measurements and floor plan.
- Cottage, office 200–500 m² — from 25,000 to 60,000 ₽.
- Residential complex floor, business center, warehouse 1,000–3,000 m² — from 80,000 to 200,000 rubles for filming and processing.
- Regular monitoring of construction — subscription model from 40,000 ₽/month for weekly scans of one section.
BIM integration, travel to another region and VR assembly are additionally paid for. Exact calculation for your object - at cost calculator in 2 minutes.
Frequently asked questions
How is a digital twin different from a regular BIM model?
BIM is a “how to be built” design model. A digital twin is an actual “as-built” slice created by scanning. They are linked: the BIM model is loaded on top of the scan, and all deviations are visible.
Is it possible to rent a property at the rough construction stage?
Yes, and this is one of the key scenarios. Scanning before covering the walls records all communications, reinforcement, and nodes. The archive is used during operation, repair and to resolve disputes with contractors.
Does the tour work on a phone and in a VR helmet?
Works in any modern browser on a PC, smartphone and tablet without installing applications. A separate version is being assembled for VR headsets Meta Quest, Pico, HTC Vive for presentations and showrooms.
How long does a finished tour last?
The storage period depends on the chosen placement format. On the 360° Space cloud we provide tour operation at a rate with technical support; on the customer’s server - as long as the customer’s infrastructure supports access; The offline version and VR build live on your hardware without a deadline.
