Scan-to-BIM Price vs Value: Why a Cheap Model Can Cost More
A low scan-to-BIM price is not a problem by itself. It becomes one when it is attached to a scope nobody wrote down, a point cloud nobody checked, a model nobody compared with the scan, or a file the design team cannot use, because then the missing work reappears as the design team’s hours after delivery, where it was never a line item. This guide explains what a scan-to-BIM price buys, where a cheap model gets expensive, and how to read two quotes that look far apart.
What the price pays for
A scan-to-BIM model is three pieces of work. The scan: the building is recorded station by station and the stations are registered into one point cloud, checked in the field, with a registration report that lists the average error of each station and the overlap between scans. The model: each element is built against the cloud at the level of development the scope names, in the BIMForum Level of Development Specification’s terms, and checked against the cloud before delivery to the Level of Accuracy the quote states. The handoff: the Revit file in your version, the registered cloud in E57 and RCP/RCS with its report, and a note of what was excluded and where the scanner could not see. The price follows the area, the level of development and how much of the building is in scope, and every one of the three pieces is either in the quote or missing from it.
Typical ranges from recent projects, for the scan and the model together: a house or an apartment, $2,000 to $4,500; interiors with the facades and the site, $2,500 to $5,000; an office or a commercial floor, $3,000 to $9,000; large buildings from $12,000, quoted on their own. The point cloud alone starts at about $1,200, and a model built from a point cloud you already have is quoted on that cloud. The guide to scan-to-BIM cost explains what moves the number within those ranges.
Where a cheap model gets expensive
Undefined scope is a more common failure than bad modeling. If the quote does not name the element categories, the reviewers argue afterwards about what should have been there. If it does not set the LOD per category, some elements come back too rough and others over-modeled. If it states no accuracy and describes no check against the cloud, nobody can verify a single modeling decision. If the Revit version is unstated, the file may not open in your Revit at all. A low number with those gaps cannot be compared with anything.
Registration matters most here: a cloud that was never checked forces the modeler to guess from weak evidence, which shows up as wall offsets, floors that do not meet and review rounds that go nowhere. Ask whether the price includes the registration and its report, and whether the cloud is delivered with the model in E57, the ASTM exchange format for 3D imaging data, and in RCP/RCS so your team can open it in Revit and check the model against it. Without the cloud, the model cannot be checked against the scan. The guide to registered vs unregistered point clouds explains what the report shows.
Accuracy is a separate question from detail: a model can carry LOD 300 detail and still be off by inches. The U.S. Institute of Building Documentation’s Level of Accuracy specification states each level as a standard deviation at the 95 percent confidence level, LOA30 being a deviation between 15 mm and 5 mm, and a quote that names the level and says how the model is checked against the cloud is selling a different product from one that does not.
Reading two quotes that look far apart
Two companies can use the same words and price different products. One includes the scan, the registered cloud with its report, the architecture and the visible structure at LOD 300, the visible systems at LOD 200, a stated LOA and a review round. The other includes an architecture-only model built from a cloud you supply, no sheets, no cloud delivered back, no stated accuracy and no review. The second is not cheaper if you needed the first. The fastest way to see the value is to put both quotes on the same lines before comparing the totals: scan included or not; cloud delivered with its report or not; Revit version; categories named; LOD per category; systems scope; accuracy stated and the check described; sheets; review rounds; exclusions listed. Filled in, the list usually shows where the price gap comes from. The guide to comparing scan-to-BIM companies walks through that comparison.
Write the scope so every quote hits the same target
Your request decides how comparable the quotes are, since each company fills a vague request with its own assumptions. Something like: “A Revit model from a laser scan for renovation design. Include the walls, doors, windows, floors, stairs and ceilings, and the visible columns and beams, at LOD 300; exclude the concealed systems, furniture and manufacturer-specific families. Deliver the Revit file in our version, the registered point cloud in E57 and RCP/RCS with its registration report, the model stated to LOA30 and checked against the cloud.” The guide to the scan-to-BIM quote checklist lists everything else to send.
A quote from us names the categories, the LOD and the LOA, the Revit version, the deliverables and their dates, and arrives within one business day of your sending the address, the LOD and the element categories. The scan-to-BIM page describes the scope, and we scan in all 50 states.
FAQ
Why is the cheapest scan-to-BIM quote sometimes the most expensive choice?
Because the gap is usually scope, not skill. A low quote often leaves out the cloud, the registration report, the systems, the sheets or the check against the scan, and the missing work comes back as the design team’s cleanup after delivery.
What should a scan-to-BIM quote state?
The element categories and the exclusions, the LOD per category, the accuracy as a USIBD LOA and how the model is checked, the Revit version, whether the cloud is delivered with its report, the sheets if any, the review rounds and the dates.
Is the point cloud part of the price?
It should be delivered with the model, with its registration report, in E57 and RCP/RCS. Without it the model cannot be checked against the scan.
How much does scan-to-BIM cost?
Scanned and modeled, a house or an apartment usually $2,000 to $4,500, interiors with facades and the site $2,500 to $5,000, an office or a commercial floor $3,000 to $9,000, large buildings from $12,000; the point cloud alone from about $1,200.
