Laser Scanning for Historic Hotel Renovations
Laser scanning for a historic hotel renovation creates a measured record of visible building geometry at agreed milestones. Capture pre-renovation conditions before demolition, return when approved strip-out exposes needed surfaces, and document selected installations before concealment. A final record supports handoff. Consistent coordinates and clear capture dates make the records usable together.
Our Approach
How we help your team
A hotel refurbishment combines existing building constraints with the building's planned use. We help owners and project teams define the conditions that should be recorded before access changes, then turn the captured geometry into the agreed documentation for design and delivery.
Certified Laser Scanning scopes the areas, access restrictions and project coordinate basis with your team. Our FARO capture and SCENE registration workflow produces reviewed data for the agreed point cloud or CAD/BIM deliverables. Preservation requirements and phased access are identified before the field plan is set.
Part 1 of 7
Record what the renovation is about to change
A hotel's existing drawings may describe an earlier refurbishment. A decorative ceiling can conceal a later alteration, and apparently repeated guest rooms can have different service routes. Start with the questions that affect the design. Identify which historic features must remain and which spaces will become accessible only after approved work begins.
For an illustrative historic hotel, that could mean capturing a retained lobby and its irregular openings before protection is installed, then returning to selected guest-room floors after strip-out. The preservation architect identifies the significant fabric and the recording detail it needs. That decision shapes the survey scope and the supporting photographs or measured drawings.

Plan four capture windows
A final scan cannot recover a ceiling profile removed months earlier. Equally, an initial scan through a finished corridor cannot measure the structure hidden above it. Plan each visit around information that becomes available or is about to be lost. Agree the required zones with the renovation manager so a change in schedule triggers a review of the capture window.
The milestones below are a starting point for scoping. Some hotels need more visits because work moves floor by floor. Others need a limited survey of a lobby, plant area or roof. Capture should follow the design and preservation decisions that require measured evidence.

| Milestone | Visible conditions to consider | Purpose |
|---|---|---|
| Before approved demolition | Retained finishes, openings and accessible existing geometry | Design baseline and preservation documentation |
| After authorized strip-out | Exposed structure and newly accessible service routes | Existing-condition coordination and scope review |
| Before new work is concealed | Selected installations and fit-sensitive interfaces | Location record or agreed dimensional verification |
| At closeout | Completed areas within the handoff scope | Dated final documentation for the receiving team |

Keep the surveys in a common reference system
Separate scan visits need a shared coordinate basis if the team will compare them. Establish references that can survive the work, with the required survey control and independent checks. A wall scheduled for removal is a poor long-term reference. Repeating a tripod location alone does not establish that two surveys are aligned accurately.
Historic England's heritage guidance explains the role of control in joining scan data and supporting repeated measurement. For a renovation, keep the capture dates with the data and document any coordinate transformations. Review alignment uncertainty before interpreting a difference between surveys. An apparent change can arise from registration or incomplete coverage as well as from the building itself.

Choose the record the design team needs
The scanner measures visible surface positions. A registered point cloud lets a team inspect that geometry and take sections through it. CAD plans or an existing-condition BIM model add interpretation. Agree which features need representation, how irregular surfaces will be treated and where an idealized model element is acceptable for the design task.
For example, a designer can cut a section through a stair and the adjacent floor in the point cloud to investigate the available space. A renovation model may then represent the elements needed for coordination. The agreed modeling rules determine how closely that representation follows irregular existing surfaces.
Historic fabric often needs context the points cannot supply. NPS laser-scan guidance distinguishes geometric capture from the interpretation of materials and construction history. Close-range photographs, field notes and measured details may be needed alongside the scan. Fragile finishes also affect how the crew can move through the space and place temporary references.
Keep retained, removed and newly installed conditions distinguishable in the issued information. Combining every visit into one undated model could leave a designer checking a proposed route against an element that has already been demolished. The receiving team should be able to identify the condition and date relevant to its decision.

A documented hotel example from Los Angeles
FARO's published Century Plaza Hotel case study describes Webcor using survey work and FARO scanning to understand the existing Los Angeles building during the renovation that began in 2016. The team compared registered scan data with the project model and investigated discrepancies in the existing geometry. Floor-elevation maps also helped the team understand the existing levels.
The practical lesson is to test the assumptions in the drawings before those assumptions govern new work. For your hotel, the useful question might concern a shaft opening, a structural interface or an existing floor level. Define the question and required check first, then request the capture and documentation that can answer it.

Plan access around hotel operations and preservation work
In an occupied hotel, access can determine whether the required view is obtainable. Room availability and housekeeping schedules need coordination, and public areas may require controlled working periods. Identify escorts and restrictions before the survey. Temporary screening or stored furniture can leave important surfaces out of view.
A representative room is useful only within an agreed sampling strategy. Record which rooms were scanned and why; older buildings may have variations that affect the refurbishment. The architect and owner should decide whether the project needs every affected room or a defined sample with stated limits. Scanning cannot establish the condition of an unvisited room.
For protected interiors, agree movement and target placement with the preservation team. A non-contact instrument still requires physical access for its crew and equipment. The record can support conservation decisions, while material investigation and approval of interventions remain with the relevant professionals.

Make the handoff useful for the next refurbishment
Owners benefit from being able to identify what was recorded and retrieve it when another project begins. Agree file formats and the receiving software, then retain the coordinate description and coverage notes with the issued data. If long-term heritage documentation is required, establish the archival requirements before commissioning the survey.
A geometric record can support later access planning or help a designer investigate a fit constraint. Asset identification and maintenance information are separate requirements that need their own agreed scope. For a scanning quote, send the renovation area, significant features and phase schedule, with the decisions your team needs the records to support.
Agree the pre-renovation record before irreversible work starts. Keep each survey tied to its capture date and coordinate basis, and scope the return visits around the surfaces that become exposed or will soon be concealed.
