How Should Architects, Interior Designers, and Engineers Be Coordinated on a Hotel Project?

In a hotel project, the investor usually starts by hiring an architect.

Then the interior designer comes on board.

The electrical project gets prepared.

The mechanical project gets prepared.

Structural, plumbing, fire safety, low-voltage, and other technical disciplines join the project.

On paper, everyone is doing their own job.

But in hotel projects, the problem often isn't that the teams are unskilled — it's that they aren't working together closely enough on the same project.

The architect has prepared a beautiful plan.

The interior designer has detailed the rooms.

The engineers have designed the technical systems.

But once execution begins, problems start to surface.

An AC duct clashes with the designed drop ceiling.

An electrical outlet ends up behind a fixed piece of furniture.

The bathroom plumbing doesn't match the planned layout.

The fire safety equipment affects the decorative ceiling layout.

The space set aside for a technical shaft turns out to be insufficient.

At this point, the problem usually isn't that one single person made a mistake.

The problem is that even though everyone thinks their own project is correct, the projects aren't talking to each other enough.

Getting a good result in a hotel project isn't just about hiring a good architect, a good interior designer, or a good engineering team.

What really matters is this:

Can these teams work toward the same goal, from the same information, in the right order?

In this article, I'll look at why coordination between the architect, interior designer, and engineers matters in hotel projects, and how you, as the investor, can manage this process more soundly.

Why Does Coordination Matter So Much in a Hotel Project?

In a residential project, certain technical mistakes can stay limited to specific areas.

But in a hotel, the same design or planning mistake can repeat across many rooms.

For example, an outlet layout in one room might be poorly planned.

That mistake creates a small problem in a single room.

But if the hotel has 30 rooms, the same mistake can repeat 30 times.

The same is true for:

• bathrooms
• AC systems
• lighting
• furniture
• plumbing
• doors
• sound insulation

That's why a small coordination mistake in a hotel project can turn into a repeating cost.

A mistake in one room isn't a single mistake in a hotel project. It's usually a multiplied mistake.

That's why project coordination isn't just about making sure the drawings don't clash with each other.

It's also about preventing wrong decisions from turning into repeating costs.

1. Everyone Needs to Answer the Same Questions at the Start of the Project

The first step of coordination is making sure the teams are designing the same project.

This might sound simple, but on many projects, decisions that aren't clear enough at the start end up getting interpreted differently by different teams as the process moves forward.

For example, there are some core topics that need to be as clear as possible before the project starts:

• What is the hotel's concept?
• Which guest profile will it serve?
• How many rooms are targeted?
• How will each room type be used?
• What will the functions of the common areas be?
• What will the hotel's operating model be?
• What's the target investment budget?
• Is the project's priority aesthetics, cost, or durability?
• In which areas will investment be made, and in which areas will more economical solutions be preferred?

The answers to these questions shouldn't stay only with the investor.

The architect, interior designer, and engineering teams need to understand the same framework too.

Because an architect doesn't just draw a room plan.

An interior designer doesn't just design a beautiful space.

Engineers don't just select technical systems.

Every decision each of them makes affects the other disciplines' work.

2. Architectural Decisions Need to Be Finalized First

One of the significant problems in project coordination is other disciplines starting detailed work while the architectural plan is still constantly changing.

For example, the interior designer might have finished a room design.

The electrical engineer might have prepared the outlet and lighting plan based on it.

The mechanical project might be finished.

Then the architectural plan changes.

A wall shifts.

The bathroom moves to a different spot.

The room layout changes.

In that case, the other projects already prepared need to be updated too.

That's why it matters for the core architectural decisions to be as clear as possible at a certain stage.

In particular:

• room layouts
• corridors
• stairs
• technical shafts
• common areas
• wet areas

moving into detailed projects without enough clarity on these core elements increases the risk of duplicate work.

But this doesn't mean the architect has to make all the decisions alone.

Quite the opposite — early feedback from the technical disciplines needs to be gathered while architectural decisions are being made.

The architectural project comes first, but it doesn't move forward independently of the technical teams.

3. The Interior Designer Shouldn't Only Come In at the End of the Technical Projects

On some projects, the process goes like this:

The building is designed first.

The technical projects get prepared.

Construction begins.

Then the interior designer comes in to try to make the spaces beautiful.

This approach can create problems, especially in hotel projects.

Because interior design decisions can directly affect the technical infrastructure.

For example:

• the bed's position
• headboard panels
• the TV's position
• the minibar
• the desk
• the mirror
• lighting fixtures

change the electrical infrastructure.

The bathroom design can affect:

• the plumbing
• the drains
• ventilation

The drop ceiling design needs to be resolved together with:

• AC
• ventilation
• lighting
• fire safety equipment

That's why the interior designer shouldn't be thought of as someone who just picks colors and furniture once the structure is finished.

Especially in hotel projects, interior design needs to progress in parallel with the architecture and the technical systems.

4. Technical Projects Shouldn't Be Prepared Without Seeing the Furniture Layout

In a hotel room, many technical decisions depend on the actual position of the furniture.

For example, planning the outlets requires answers to these questions:

• Where will the bed be?
• Will there be a nightstand?
• Which wall will the desk be on?
• Where will the TV be?
• Where will the minibar be?
• Where will the space for a hair dryer be?
• Where will luggage be set down?

An electrical plan made without knowing the furniture layout can be technically correct.

But it can turn out to be impractical from an operational standpoint.

The same is true for lighting.

A lighting point can look correct on an empty room plan.

But once the furniture is in place, it can end up off-center from the bed, or fail to light the work area sufficiently.

That's why it's especially useful for all the disciplines to work together on a sample room.

A hotel room needs to be designed not as an empty architectural plan, but as a space the guest will actually use.

5. Everyone Needs to Check the Ceiling Plan Together

One of the most critical coordination points in a hotel project is the ceiling.

Because many different systems can be present in the ceiling at the same time.

For example:

• AC vents
• ventilation
• sprinkler systems
• fire detection equipment
• lighting
• speakers
• camera systems
• decorative elements.

If each team prepares its own project separately, clashes can surface during execution.

That's why building a coordinated ceiling plan, especially in common areas and room types, provides a major benefit.

Ideally, the architectural and interior design plan and all the technical systems should be evaluated on the same plan.

That way, questions like these can be answered before execution begins:

• Is there enough space for all the equipment?
• Can the ceiling height be maintained?
• Does the technical equipment block each other?
• Does it compromise the lighting design?
• Is maintenance access possible?

Many costly execution mistakes can be prevented with one good coordination meeting before the ceiling is closed up.

6. Engineers Shouldn't Just Work Off the Plan Handed to Them

The engineer's job isn't just to place technical systems onto the architectural plan they're given.

In a good coordination process, the engineering teams need to give early feedback on the project too.

For example:

"This shaft isn't big enough."

"This system is hard to install at this ceiling height."

"This equipment needs a separate space."

"This room layout increases the plumbing cost."

When feedback like this is given at the project stage, the architectural solution can be adjusted for a healthier outcome.

But if these problems surface during construction instead, the options become fewer.

So an engineer's contribution to the project isn't just technical calculation.

It's also giving early warning about whether the architectural and operational decisions are actually executable.

7. Everyone Needs to Work Off the Same Current Project

One of the simplest but most common causes of coordination problems is different teams using different versions of the project.

The architect has updated the final plan.

But the electrical engineer is working off an old plan.

The interior designer is using a different revision.

The execution team started work based on a previously sent PDF.

As a result, different projects end up getting built in the same building.

That's why a simple but important system needs to be set up in project management.

Every project revision's:

• date
• version number
• reason for the change
• which teams it affects

needs to be tracked.

For example:

Revision 08 — August 15

• Room 104's bathroom door was changed.

•

• The floor's technical shaft was widened.
• The lobby ceiling height was updated.

Which disciplines each of these changes affects should be clearly stated too.

The current project needs to be the project everyone can access.

8. Hold Coordination Meetings Regularly, Not Just When a Problem Comes Up

On many projects, teams only meet once a major problem has already surfaced.

But the goal of coordination isn't finding a solution after a problem happens — it's catching the problem before it happens.

Regular meetings can be held especially during the project and execution stages.

For example, a weekly meeting can cover topics like these:

Architecture

• What are the latest changes?
• Is there any deviation in execution?
• Are there areas that need a new decision?

Interior Design

• Have the furniture and material decisions been finalized?
• Are there any changes affecting the technical systems?

Electrical and Mechanical

• Is there a clash between the projects?
• Has a new technical need come up?
• Are there details that need to be resolved before execution?

Execution

• Is there anything on-site that doesn't match the project?
• Is there a delay in the work schedule?
• Has a new cost risk come up?

These meetings don't need to run for hours.

What matters is that decisions are recorded and owners are assigned.

9. Don't Move to Mass Execution Without Building a Sample Room

I think one of the most valuable practices for coordination in hotel projects is building a sample room.

A room gets finished as completely as possible.

Furniture gets placed.

Lighting gets turned on.

The bathroom gets used.

The AC gets tested.

The outlets get checked.

The room gets walked through from the guest's perspective.

At this stage, many details unnoticed on the drawings can surface.

For example:

• an outlet might be in the wrong place
• the nightstand might turn out too small
• the light might not reach the bed sufficiently
• the AC might be blowing directly onto the bed
• the towel hook might be positioned incorrectly.

Catching these mistakes before every room is built provides a huge advantage.

A sample room isn't really built just to see the design.

A sample room is where all the teams test the same project in real life.

10. The Investor's Decisions Can Be One of the Biggest Variables in the Process

When talking about project coordination, it isn't enough to only evaluate the architect, interior designer, and engineers.

The investor is also an important part of the process.

Because many changes during the project come from the investor.

A new idea gets noticed.

A different execution admired at another hotel.

A material change is wanted.

A new area gets added.

If each of these changes isn't communicated to the teams correctly, coordination problems can come up.

That's why, as the investor, it matters that decisions made are:

• not lost as verbal conversation
• communicated to the project teams
• evaluated for cost and timeline impact
• recorded in a project revision if needed

If a decision made on the project doesn't get entered into the drawings or a record system, everyone can end up remembering it differently after a while.

11. There Should Be One Coordination Owner

On large or complex projects, expecting everyone to coordinate with each other on their own may not be realistic.

That's why it helps to have a designated coordination owner within the project.

This person can be:

• a project manager
• the architect
• a representative working on behalf of the investor

or another professional suited to the project structure.

What matters isn't who this person is — it's that the answers to these questions are clear:

• Who is tracking the final decisions?
• Who is distributing the project revisions?
• Who is tracking clashes between disciplines?
• Who is recording the meeting decisions?
• Who is checking on open items?

It's possible for more than one person to share this responsibility.

But having a specific person ultimately responsible for tracking the process can prevent a lot of issues from being left hanging.

12. Keep Communication Strong Between the Site and the Office

What's drawn on the project and what's built on-site aren't always identical.

Differences in the existing structure.

Measurement problems.

Unexpected plumbing.

Execution mistakes.

Material changes.

All of these can come up on-site.

That's why the site team needs to be able to access the project and communicate the problems they encounter to the right people.

Similarly, a project change made in the office absolutely needs to reach the site too.

Otherwise, the project gets updated in the office, but execution continues based on the old drawing.

That's why, for critical changes:

• The problem gets identified.
• It's evaluated with the relevant teams.
• A decision gets made.
• The project gets revised if needed.
• The current decision gets communicated to the site.
• Execution gets checked.

If any link in this chain is missing, the same problem can come up again.

A Short Checklist for Coordination in a Hotel Project

Project Start

• Has the hotel's concept and goal been shared with all the teams?
• Are the room count and core usage scenarios clear?
• Has the target budget been determined?
• Is it clear which priorities matter most in the project?

Architecture and Interior Design

• Has the core architectural plan been made clear enough?
• Was the interior designer brought into the process early?
• Was the furniture layout evaluated before the technical projects?

Technical Projects

• Are the electrical and mechanical teams working off the current architectural plan?
• Are the technical shafts and equipment spaces sufficient?
• Have the ceiling plans been checked together with all the disciplines?
• Is there a clash between the technical systems?

Project Management

• Can everyone access the same current project version?
• Are revisions being recorded?
• Are regular coordination meetings being held?
• Are owners being assigned for meeting decisions?

Execution

• Is the site team working off the current project?
• Are the problems that come up on-site being recorded?
• Was a sample room built?
• Was the sample room checked with all teams before moving to mass execution?

Conclusion: A Good Project Isn't the Sum of Good Teams

You can work with a very good architect, a very good interior designer, and very good engineers on a hotel project.

But if these teams move forward independently of each other, the project can still run into problems.

Because a hotel isn't a structure produced by a single discipline.

Architectural decisions affect the technical systems.

Interior design decisions affect the electrical and mechanical infrastructure.

Technical requirements affect ceiling height and spatial design.

And operational needs can change the whole project.

That's why what matters for a successful project isn't just choosing the right people.

These people need to:

• understand the same goal
• have access to the same current information
• talk to each other at the right time
• record the decisions that get made

For the investor, one of the most important roles in the process isn't technically intervening in the teams' work.

The real role is building a system where the right questions get asked and everyone works together.

A good project doesn't come from good drawings coming together — it comes from different disciplines completing each other.
