in a fraction of the time.'
piece by ensuring the as-built structures
lined up with design plans. Other customers
soon began suggesting the same thing and
ClearEdge3D went to work on developing its
next product, Verity. Cone joined the company about a year ago to help develop and test
the software.
Verity takes some of the concepts behind
EdgeWise and repurposes them to focus on the
general contractor market. Where EdgeWise
functions as a computer aided as-built modeling tool, Verity is a comparison tool focused on
quality assurance. It is a deep dive to solve the
core problems of quality in the construction
industry. "The biggest change was moving
from an analyze-everything[process with
EdgeWise] to letting the user choose what they
want to analyze," Cone says. This workflow
change aligns Verity with other construction
industry processes like clash-detection.
Verity works with any scope of work on
a project, from mechanical, electrical and
plumbing (MEP) systems to the concrete,
walls and finishes. The software can detect
installation status and inform project stakeholders whether a component is in place,
missing or obstructed from the scan. Knowing the status of that piece helps contractors
know whether that part of the project is on
schedule. Clients can also set the tolerance
level for the work they are analyzing, and
the software will compare the as-built point
cloud against the CAD model, then automatically flag components that exceed those
tolerance limits.
The software is a companion application
to Navisworks, a 3-D design review package.
This integration allows users to update the
Navisworks elements to their as-built positions, clash-detect the position of the as-built
model against the design or fabrication model and visualize the out-of-tolerance work

using a color-coded classification scheme. Unlike other comparison
tools that offer heat maps and measurements between the model
and the point cloud, Verity fits solid model elements to the as-built
point cloud, allowing it to make solid-to-solid model comparisons
and provide more accurate and detailed variance data. The software
then generates reports to stakeholders to communicate problems
with the building.
The system is not designed to replace quality assurance professionals and inspectors, but rather to dramatically improve their
efficiency. Says Cone: "Our goal was to give quality professionals a
tool to let them check 100 percent of the installed work in the same
time it now takes them to spot check 5 to 10 percent."

Quality Control
Because it can examine the entire structure, Verity solves a fundamental problem with how the construction industry approaches
quality inspections: the spot check methodology. Spot checking
randomly tests small sets of work to gauge whether there are more
widespread quality issues. It's an effective methodology in manufacturing facilities and on assembly lines where the consistency of
production means that a small sample of a batch is likely to reveal
any present faults. "Spot checking works when it's random because
you can't find ways to beat the system," Cone says.
But on a construction job, Cone argues that spot check sample is
rarely ever random. Supervisors know what problems to look for
based on past job experience. Workers learn quickly what the superintendent in charge of their area is worried about and what parts are
most likely to receive inspection attention. Those items are likely to
meet standards, but other areas can be easily overlooked.
With more than 100 clients using Verity, ClearEdge3D has seen a
clear pattern in those quality issues. "What we find are the biggest
mistakes are where no one is looking," Cone says. He recalls one
customer that was beta-testing Verity to check for installation issues
on the perimeter of a project. The software discovered a major issue
on the interior of the building. The project's design called for a slope
in the middle of the building's footprint to facilitate drainage, but
the steel and metal deck was fabricated and installed flat.
Verity picked up on the deviation from the expected design and
the quality team alerted the project stakeholders. Fortunately, the
concrete had not yet been poured so the contractor was able to fix
the problem within a day and stay on schedule. "If the slab had
already been poured, that's a $50,000 mistake, and there's no way
