Online construction control: a new standard for developers
Online construction control: a new standard for developers In short: 3D tours replace on-site visits by foremen and technical supervision with a digital model of the object accurate to the centimeter. One day of filming a floor reduces the number of controversial issues between the contractor and the customer by 60% and records hidden work in the form of an evidence base. Online 3D construction control is a format for remote supervision in which each stage of construction is recorded in the form of a walkable digital twin of the object. The developer, technical supervision, investor and designer go into the browser and see the site as if they were there in person - with the ability to measure distances, compare stages and rewind the work history. According to developers who have switched to regular 3D recording, the average time for approval of hidden work reports is reduced from 7–10 days to 1–2. The technology is especially in demand at sites over 5,000 m² and for remote management of a portfolio of construction projects in different regions. Why does a construction site need a 3D tour? Digital recording of an object solves several typical problems of a developer at once - from disputes with a contractor to claims from buyers of finished housing. Specific benefits: Save 40% time on detours. The chief project engineer, who oversees 4–6 sites, spends up to 25 hours a week on the road. A 3D tour replaces 70% of visits: checking the geometry of walls, engineering systems and quality of finishing is available from the office. Evidence base for hidden work. Each shooting point receives coordinates and a time stamp. In case of disputes with a general contractor or subcontractor, the tour works as a notarized record - you can see what and when was done before the screed, plaster or suspended ceiling was closed. Reduction of the acceptance cycle by 30–50%. Shareholders and commercial tenants receive access to a tour of the finished space prior to a personal visit. Controversial issues are identified in advance, and a face-to-face examination takes 20 minutes instead of an hour. Sales acceleration by 15–20%. A tour of a facility under construction, updated once a month, increases buyer confidence: they see real progress, and not renderings from a prospectus. Quality control of finishing before signing KS-2. Matterport scanning accuracy is up to 1% in linear dimensions. This is enough to challenge the volumes with the contractor without repeated measurements with a tape measure. How does this work? The process is divided into three stages: filming, processing, delivery of the tour to the customer. An operator with a Matterport Pro3 camera or similar certified equipment goes to the site. The shooting points are placed in increments of 2–3 meters—for a typical floor with an area of 1,000 m², this is about 80–100 scans and 4–5 hours of work. The camera simultaneously takes 360° panoramas and collects a cloud of points using lidar: the output is a geometrically accurate 3D model, and not just a stitching of photographs. Processing and assembly of the tour takes from 24 to 72 hours depending on the size of the object. The finished tour includes Dollhouse mode (a general view of the building with a section of floors), floor plans with automatic dimensions and a tool for measuring distances directly in the browser. You can place comment marks on the site with reference to the contractor’s tasks - each comment has exact coordinates in space. 360° Space offers three options for storing and delivering a tour: hosting on the company’s cloud platform with high-speed servers and technical support, deploying the tour on the customer’s own infrastructure (for developers with information security requirements) or offline assembly - a standalone version for PC and a separate build for a VR headset that works without the Internet in closed security facilities. The regularity of filming is selected according to the stages of work: usually developers fix the object before closing each layer - after the monolith, before plastering, before installing floors, at the end of finishing. For active construction, once every 2–4 weeks is optimal. View all projects → How much does online 3D construction inspection cost? The cost of shooting is calculated based on the area of the object and the complexity of access. Approximate range for the market and tariffs of 360° Space: Up to 500 m² - from 25,000 ₽ per departure, ready tour in 1-2 days. 500–2,000 m² — 50–120 thousand rubles, optimal format for commercial properties and townhouses. 2,000–10,000 m² — 120–400 thousand rubles, typical cost of a floor of a residential complex or production workshop. From 10,000 m² - individual calculation; for a regular series of shootings there is a 15–25% discount. Additionally, you pay for the placement of the tour (or a one-time deployment on the customer’s server) and integration with the developer’s CRM or BIM system, if required. It is more convenient to calculate the exact estimate for a specific object in a calculator indicating the area, number of floors and the desired frequency of repeated surveys. Frequently asked questions Can a tour be used as evidence in arbitration? Yes. The tour records the geometry and condition of the object with reference to the time of shooting. When drawing up an acceptance or examination certificate, the 3D model is accepted as visual evidence along with photographic recordings and measurement protocols. How accurate are the measurements within the tour? The accuracy of Matterport Pro3 and comparable cameras is about 1% in linear dimensions at a distance of up to 10 meters. This is enough to check the final dimensions of premises, openings and calculate the volume of work in disputes with the contractor. How often should a subject be re-shot? For active construction - once every 2-4 weeks and always before closing hidden work. For a finished property at the sales stage, one survey with updating during redevelopment or repair is enough. Is the tour only available online or can it be used without internet? 360° Space provides tours in three formats: in the company’s cloud, on the customer’s server, and as an offline build for a PC or VR headset. The offline version is in demand at sensitive facilities and in field conditions without a stable connection. Calculate costProject catalogMatterport
