A building owner commissions a survey of a 1970s office building ahead of a planned interior renovation. The fieldwork goes smoothly, the data is captured on schedule, and a few weeks later the files arrive. The architect's team works in 2D and cannot use the delivered 3D model. The mechanical engineer needs ceiling-space detail the drawings never show. Nobody asked, before the first scan was taken, what the deliverable was supposed to do.

When evaluating as-built services, most owners focus on accuracy, price, and schedule. Those factors matter, but the final deliverable’s format deserves equal attention because it determines whether the information can actually be used.

Why the Deliverable Should Be Chosen Before Fieldwork

The deliverable is not a formatting choice made at the end of a project. It shapes everything that comes before it. The intended output influences how densely a space is scanned, which areas need extra coverage, what level of accuracy must be specified, and how many hours of modeling or drafting follow the fieldwork.

Deciding late usually leads to one of two outcomes: paying to convert data into a format it was never captured for, or sending a crew back to the site to fill gaps.

Point Clouds: The Raw Record

A point cloud is the direct output of 3D laser scanning: millions of measured points that together form a precise, three-dimensional record of a space. It captures everything within the scanner's line of sight, including conditions no one thought to ask about at the time.
Point clouds are valuable to engineers and technical teams who want to take their own measurements on demand, and they serve as a permanent archive that can be revisited when new questions come up. The limitations are practical. Files are large, they require specialized viewers, and a point cloud is not a drawing. Someone still has to interpret the data before it becomes a plan or a model.

2D CAD Drawings: Familiar and Efficient

For many projects, a well-prepared set of 2D CAD drawings is exactly the right tool. Floor plans, exterior elevations, and building sections are familiar to nearly every architect, engineer, and facility manager, and they open in software most teams already own.
CAD drawings work well for space planning, leasing, straightforward interior renovations, and maintaining a clean record set. They are typically faster and less expensive to produce than a full model. Their limitation is dimensional: systems above the ceiling and complex spatial relationships are hard to understand on a flat sheet.

Revit Models: Intelligent Data Across the Building Lifecycle

A Revit model goes beyond geometry. Walls, doors, equipment, and systems are represented as intelligent objects that carry information, so the model can generate plans, sections, schedules, and 3D views from a single source.
Models are the best fit for complex renovations involving multiple disciplines, for owners planning long-term facility management, and for buildings where the spatial relationships between systems matter. The key is matching the model's Level of Development (LOD) to its intended use.

Deliverable Needs in Industrial Facilities

Industrial buildings put deliverable decisions to the test. An industrial as-built package often combines a registered point cloud with selectively modeled elements, such as structure and critical utility runs, so the team gets precision where it matters without paying to model every conduit.

Timing is another factor. When an industrial as-built service is needed during a due diligence period that may last only 30 days, the deliverable must be defined up front so field capture and processing can move quickly and produce information decision-makers can act on.

Questions to Ask Before You Commit

Before signing a proposal, answer a few simple questions. Who will use the deliverable, and what software do they work in? What decisions will it support? Does it need to serve a single project or the life of the building? How accurate does it need to be, and in which areas? Clear answers turn a generic scope into one that fits the job.

For owners and design teams seeking reliable as-built services, Architectural Resource Consultants (ARC) is a trusted partner. Since 1997, ARC's licensed architects and LOA-certified technicians have documented the built environment nationwide, bringing more than 25 years of experience to every project. ARC helps clients reduce risk by choosing and delivering the point clouds, CAD drawings, and Revit models their projects actually need.
