Capture What Was Built. Document What Will Be Hidden.

Construction changes quickly. Once walls are closed, ceilings installed, and finishes completed, important information about how a building was constructed can become difficult to recover.

Ilios Remote Sensing provides high-precision 3D laser scanning and interactive visual documentation at key construction stages.

Terrestrial laser scanning creates measurable records of constructed geometry and exposed infrastructure.

iGUIDE visual capture creates an intuitive, navigable record of what the project looked like at a particular stage.

Together, they can help project teams identify discrepancies earlier, document concealed work, preserve project knowledge, and create useful records for future maintenance and renovation.

Measure what was built. Document what's about to disappear.

Construction Documentation

& As-Built Verification

Document Construction Before the Next Phase Begins

Not every construction question requires the same type of documentation.

When the question is:

“Where exactly was this built?”

High-precision terrestrial laser scanning provides measurable geometric information.

When the question is:

“What was here before it was covered?”

An iGUIDE capture provides an intuitive visual record that owners, contractors, consultants, and facility personnel can revisit later.

For many construction projects, the two technologies complement each other.

Terrestrial Laser Scanning

Where exactly is it?

High-density terrestrial laser scanning captures visible construction within a three-dimensional coordinate system for dimensional documentation, existing-condition capture, concealed-infrastructure documentation, and comparison with project information.

iGUIDE Visual Documentation

What was here?

iGUIDE creates a navigable visual record of the project, allowing users to virtually return to a particular stage of construction and see what existed before subsequent work concealed it.

Document Construction Before the Next Phase Begins

Capturing a project while work remains exposed provides information that may become difficult or impossible to obtain later.

Depending on what needs to be documented, Ilios can provide precision 3D measurement, navigable visual documentation, or both.

Terrestrial Laser Scanning — Measure Constructed Conditions

A dimensional discrepancy discovered early may be relatively straightforward to address. The same issue discovered after other trades have built around it can lead to demolition, rework, delays, and additional cost.

Terrestrial laser scanning captures millions of measurements to create a detailed three-dimensional record of constructed conditions.

Applications can include:

  • Structural geometry

  • Walls, columns, slabs, and openings

  • Penetrations

  • Mechanical and equipment locations

  • Existing conditions

  • Dimensional documentation

  • Construction progress

  • As-built documentation

The resulting point-cloud data can support measurement, coordination, analysis, and comparison of constructed conditions with design information.

Measure what's been built before the next phase depends on it.

iGUIDE — Create a Navigable Visual Record

Not every construction question requires precision measurement.

An iGUIDE capture allows owners, contractors, consultants, and facility personnel to virtually return to a documented stage of construction and see what was visible at the time.

Unlike collections of individual photographs, the navigable environment preserves spatial context. Users can understand which room they are viewing and how documented components relate to walls, doors, windows, and surrounding spaces.

Interactive tags can add information directly to the tour, including equipment identification, electrical and data systems, plumbing, shutoffs, blocking, installation information, and links to supporting documentation.

Capture the Project at Key Milestones

Create a Record of Construction Over Time

A single capture records one moment. Multiple captures can document how the building changes throughout construction.

Existing Conditions

Document the structure or site before work begins.

Structure & Rough-In

Record structural geometry and exposed electrical, plumbing, mechanical, communications, and other building systems.

Pre-Close

Capture infrastructure immediately before drywall, ceilings, flooring, cabinetry, and other finishes conceal it.

Completion

Document finished conditions and create a final as-built record.

Terrestrial Laser Scanning — When Dimensional Information Matters

Laser scanning can be performed at selected milestones where accurate geometry, measurement, or comparison with design information is important.

Pre-close scanning can also preserve measurable 3D locations of exposed infrastructure before it disappears behind finished surfaces.

iGUIDE — When Visual Documentation Matters

iGUIDE can efficiently create navigable records of project conditions at selected stages.

The resulting captures allow project teams and owners to return virtually to previous stages and understand how the project looked before subsequent work occurred.

For projects requiring both measurable spatial information and intuitive visual documentation, the two technologies can be combined.

Reduce Uncertainty and Preserve Project Knowledge

Better Documentation During Construction — and After

Construction projects involve multiple contractors, changing personnel, concealed work, and constantly evolving site conditions.

When a question arises months or years later, determining what existed at a particular point in the project can be difficult.

Dated laser scans and visual captures can provide contemporaneous records of observable conditions, including:

  • Existing conditions before work began

  • Work completed at project milestones

  • Concealed installations

  • Conditions before subsequent trades began work

  • Changes between successive captures

  • Areas later involved in a claim or dispute

This documentation does not determine liability or replace engineering, inspection, contractual, or legal processes. It can provide useful supporting evidence and reduce reliance on memory or disconnected photographs when questions arise.

It can also preserve information after the people who originally constructed the building have moved on.

Owners and facility teams can reference the documentation when planning renovations, maintenance, equipment installation, electrical or plumbing modifications, network upgrades, building-system investigations, and future construction.

The information can also be shared remotely with architects, engineers, contractors, maintenance personnel, and other project professionals.

People change. The record remains.

The Right Capture for the Right Question

Terrestrial laser scanning and iGUIDE visual documentation provide different types of information. The right approach depends on what needs to be documented—and how precisely.

iGUIDE — When You Need to See and Understand the Space

Best suited for:

  • Construction progress

  • Navigable visual documentation

  • Pre-drywall visual records

  • Interactive information tags

  • Remote review of documented conditions

The question it answers:
What was here, and what did it look like?

Terrestrial Laser Scanning — When You Need Precise 3D Information

Best suited for:

  • Structural geometry

  • Dimensional documentation

  • Precise locations of exposed infrastructure before concealment

  • Data for comparison with design information

  • Precision as-built documentation

The question it answers:
Where exactly was it recorded?

Terrestrial Laser Scanning + iGUIDE — When You Need Both

For projects where both visual context and measurable spatial information are valuable, the technologies can be combined.

This is particularly useful for:

  • Pre-close documentation

  • Complex mechanical, electrical, and plumbing installations

  • Construction milestone documentation

  • Long-term facility and renovation records

The questions they answer together:
What was there, what did it look like, and where was it recorded?

The objective is not to use the most complicated technology on every project.

It is to capture the information that will matter later, at the level of accuracy the project requires.

Capture It Before You Need It

Once construction is concealed, recovering information about what lies behind finished surfaces becomes considerably more difficult.

Capturing the project at the right stages can provide useful information during construction while creating a record that remains valuable throughout the life of the building.

Ilios Remote Sensing can develop a capture approach based on the project—using high-precision laser scanning, interactive visual documentation, or both.

Measure what was built. Document what's about to disappear. Preserve the record.
