For field operators, even a simple task like locating a valve in an 8,000-square meter building used to require site visits, physical measurement taking, and time-consuming inspections. By uploading their reality capture data to a 3D scan data management platform, SIAAP teams can now visually identify assets in a 3D environment, take measurements remotely, and plan interventions without needing to be physically on site. This has considerably reduced the number of site visits needed, particularly among its operations and maintenance team. As well as saving time, it also saves unnecessary site exposure, reducing the chance of incidents.
Outdated or inaccurate plans are a common pain point in infrastructure retrofits. By using point cloud data to verify existing conditions, SIAAP ensures that new projects reflect reality. SIAAP’s engineers visually assess whether models match the actual built environment, eliminating costly rework and improving construction precision. In fact, SIAAP estimates that by comparing its scan data to BIM models digitally, it saves the team four hours on average.

SIAAP’s digital transformation also includes object-based progress monitoring. This automates deviation detection by comparing scan data to digital models, showing what’s been built accurately, what’s misaligned, and what’s missing. With this data, project managers receive actionable metrics on construction accuracy – down to specific equipment types – streamlining quality assurance.
Teams now have the full picture, with data that wasn’t previously accessible or interpretable not only now easy to understand but easy to collaborate on, fostering better communication and alignment. “The ability to show the existing context to all stakeholders during review and concept meetings enhances positive exchanges and common understanding between stakeholders, ultimately leading to smoother-run projects.”
Reality capture isn’t just for construction. At SIAAP, scan data is integrated across the entire asset lifecycle, from design and engineering to operations, maintenance, and even employee onboarding. Staff who’ve never visited a site can virtually explore facilities before setting foot in them - a valuable benefit that improves familiarity and safety.
Located assets in 3D view.
SIAAP has imported over 6,000 pieces of equipment and 120,000 documents into their centralized 3D data platform, achieving major efficiencies in asset tracking, planning, and collaboration. Connecting this with visualization and measurement tools, they’ve transformed how teams access and use their data, empowering them to make faster decisions and saving hundreds of hours annually by minimizing site visits, rework, and project delays. A notable example of 3D scan data proving its value was when it revealed existing beams that had been overlooked in the design. If the team hadn’t spotted these on their scans during the design phase, work would have started and then had to be stopped while the design was updated. The result would have been costly delays and rework for the contractors and subcontractors and ultimately holding up the restarting of the plant, which would have commercial implications.
Reality capture brings significant efficiencies for water utilities at a time when many are looking to modernize their outdated infrastructure and trim operating costs. SIAAP’s transformation has shown that digitizing and unifying infrastructure data not only saves time and money, but also enhances safety, sustainability, and long-term resilience. For companies seeking to upgrade facilities, reality capture can offer a low-friction and scalable route to smarter operations and ultimately better commercial outcomes.
