Tight schedules leave no room for guesswork
Earlier this week I traveled to Washington to scan a new aquatic facility where an adjustable obstacle course will eventually hang above the pool. When the project opens to the public, visitors will move across suspended obstacles that shift and reconfigure to create different course layouts. Behind that experience sits a structural system that must align precisely with the building that supports it. Before fabrication begins, the team must confirm where the structural anchors actually exist in the roof framing. Once fabrication starts, the geometry of that system becomes fixed. If the anchors in the building differ from the design assumptions, the fabricated components must account for those differences before installation crews arrive.
Walking into an active jobsite
When I arrived onsite, the building remained in the middle of construction. Tile crews worked along the waterline installing the first band of finish tile while concrete crews continued forming and pouring sections of the surrounding deck. Temporary railings and caution tape surrounded the pool basins, and ladders and materials sat around the perimeter as different trades moved through the space. The pools themselves had taken shape, but finishes and deck work still progressed across the area. For scanning purposes, the timing worked well. The structure above the pool remained fully exposed, allowing a clear view of the roof framing and the anchor points that will eventually support the obstacle system.
Looking at the structure that holds the system
The real focus of the scan sat above the pool. Steel roof trusses stretched across the width of the building, creating a large open span with no interior columns over the water. Welded into that structural steel were the anchors that will eventually carry the suspended obstacle system. Each cable, bracket, and frame component of the course will connect to those anchors. The design drawings show where those anchors should exist, but the building itself determines where they actually landed during construction. Small variations in steel erection, layout, and installation tolerances often shift structural elements slightly. The only way to confirm their exact location is to measure the structure directly.
The question fabricators always ask
Fabrication shops rely on precision. When they cut steel, weld brackets, and assemble structural components, the geometry of those parts must match the connection points waiting in the building. For suspended systems like this obstacle course, that relationship becomes critical. The distance between anchors, their elevation above the pool deck, and their alignment relative to each other determine how the entire system will hang and function. If those anchors differ from the original design layout, the fabrication team must know before manufacturing begins. Anchors welded into structural steel cannot move easily after installation. Confirming their position early prevents expensive adjustments later in the project.
When assumptions reach the jobsite
Anyone who has worked in construction has seen the moment when installation slows and investigation begins. A crew lifts a fabricated assembly into place expecting it to align with the structure in front of them. At first everything appears correct. Then someone notices the mounting points do not line up as expected. Work pauses while installers pull out tape measures and open drawings to understand what changed. Fabricators review shop drawings while engineers determine whether field adjustments will work safely. Meanwhile the project schedule continues moving forward. Crews wait while the team searches for answers, and other trades begin stacking up behind the delay. Time disappears quickly when uncertainty reaches the jobsite.
Capturing the structure as it exists
To remove that uncertainty, we scanned the entire pool environment along with the roof structure above it. LiDAR scanning captures millions of measured points throughout the space, creating an accurate digital record of the building geometry. The roof trusses, anchor points, pool basins, and deck surfaces all become part of a measurable environment. The team can verify distances between anchors, confirm their height above the pool deck, and identify offsets between structural members. Instead of relying on assumptions about the building, the project team can work from a measured representation of the structure that actually exists in the field.
Turning the scan into fabrication-ready information
After completing the scan, we converted the captured geometry into a detailed Revit model of the entire pool area. The model represents the building exactly as it exists, including the structural roof framing, the welded anchor points, the pool shells, and the surrounding deck geometry. From that model we produced a full set of DWG drawings for the project team. Those drawings allow the fabricator and design team to review the anchor layout using tools that fit directly into their workflow. They can verify the exact position of each anchor, measure the distance between mounting points, and confirm elevations relative to the pool deck. If any anchor differs from the original design assumptions, the fabrication team can adjust connection components and assembly geometry before materials reach the jobsite.
Why this moment in the schedule matters
The timing of this scan matters just as much as the data it produced. At this stage of construction, the structural steel had already been erected and the anchors had been welded into place. At the same time, finishes and ceilings had not yet closed off the structure above the pool. That window between steel erection and final finishes often provides the best opportunity to verify structural conditions. The anchors remain visible, the geometry of the building remains accessible, and fabrication decisions can still adapt to the measured conditions. Waiting until later in the project would place more finishes and systems in the way while reducing the opportunity to adjust fabrication.
Fabrication with confidence
Once the team verifies the anchor geometry, fabrication becomes far more predictable. The shop can build assemblies that match the building exactly as it stands today. When installers arrive onsite later in the project, they work with components that already account for the structure above the pool. Installation becomes a matter of placing components rather than solving unexpected problems. Crews can focus on the work they planned to perform rather than investigating differences between drawings and reality.
Construction always reveals reality
Every construction project begins with drawings that describe how the building should come together. As the project progresses, the physical building reveals small variations along the way. Steel moves slightly during erection. Layout lines shift as work continues. Trades make adjustments that allow construction to move forward. Those variations represent the normal process of building complex structures. Measuring existing conditions allows teams to understand those changes before fabrication depends on them.
Clarity before installation
For this aquatic obstacle system, scanning the structure provided the project team with a clear understanding of where the anchors actually exist within the roof framing. The Revit model and DWG drawings now give the fabricator the information needed to verify the geometry and adjust fabrication pieces accordingly. When installation begins later in the project, the system will align with the building because the fabrication already reflects the measured conditions. That small step removes uncertainty and allows the project to continue moving forward with confidence.
At Precision 3D Scanning, we believe construction works better when truth is clear, shared, and measurable. We bring clarity to construction by measuring reality, not assumptions.
