| Cost Line | Modular (150 keys) | Conventional (150 keys) | Why It Diverges |
|---|
| Guest module fabrication | $78,000–$112,000 / key | n/a | Factory labour at $28–42/hr vs $65–95/hr site labour |
| Superstructure & shell | $52,000–$71,000 / key | $61,000–$88,000 / key | No scaffolding, no weather cladding sequence, no formwork |
| MEP rough-in | $19,000–$26,000 / key | $24,000–$34,000 / key | Bench assembly, 22% less rework on average |
| Site works & foundations | $14,000–$23,000 / key | $21,000–$33,000 / key | Perimeter slab and pile caps only; no full footprint slab |
| FF&E | $9,000–$14,000 / key | $9,000–$14,000 / key | Parity, brand standard sets this number either way |
| Preliminary financing period | 10–13 months | 20–26 months | Carry is charged monthly on the drawn balance |
The financing line is where modular quietly wins. On a $21M construction loan at 8.5% interest, each month of programme removed is roughly $149,000 of interest carry avoided, plus the earlier start of revenue. A typical 150-key select-service property stabilising at $118 RevPAR on 68% occupancy generates about $4.4M of room revenue per year . So each month the opening moves forward is worth around $366,000 at the top line and considerably more once the asset is valued on stabilised NOI.
Who Owns What: Responsibility Split on a Modular Hotel Programme
The single most expensive misunderstanding on a modular hotel is where the developer’s obligations end and the factory’s begin. On a conventionally built hotel the boundary is drawn by trade contracts. On a volumetric programme it is drawn by module delivery, and every gap in that line becomes a change order. The table below is the split we contract to, with the column that actually matters in negotiation: the decision that closes the boundary.
| Work item | MODURA scope | Developer / consultant scope | Decision that closes the boundary |
|---|
| Geotechnical investigation | Reviews report for foundation interface | Commissions the survey and bears the risk of what it finds | Signed geotechnical report issued before module design freeze |
| Foundation and podium | Provides hold-down and bearing-point loads | Designs and builds to those loads | Setting-out survey accepted by both parties |
| Module structure and envelope | Full scope, single contract, serial-number traceability | Approves finish schedule and exterior palette | Signed prototype compliance matrix |
| MEP rough-in inside modules | Installed and pressure-tested in the factory | Specifies the systems standard | Factory witness test signed off before shipment |
| Inter-module connections | Connection design and materials supplied | Erection contractor makes the joints on site | Interface drawing issued at IFC stage |
| Vertical risers and plant rooms | Module-side stubs only | Site-built riser and central plant | Stub-out schedule locked with the MEP engineer |
| Brand technical services review | Provides as-built records and test data | Owns the franchise submission and the review meetings | Franchisor comment log closed out |
| Insurance and title during transit | To the delivery point named in the contract | From delivery point onward | Bill of lading naming the risk-transfer address |
Two of these rows cause most of the disputes we see. The foundation row, because a modular building is far more sensitive to setting-out tolerance than a site-built one: modules are rigid and cannot be persuaded into place. And the riser row, because developers routinely assume the factory is delivering a finished wet core when it is delivering module-side stubs that a site trade must connect. Our foundation systems guide covers the tolerance question in detail, and our contract types comparison sets out how each split is priced.
The Brand-Standard Gap Most Developers Miss
Franchise agreements do not just specify finishes, they specify assemblies. The two clauses that most often delay a modular hotel are acoustic separation and fire-rated corridor construction, because a factory must prove the assembly before the first module ships, not after the first inspection fails. Our guest modules are built to STC 55 / IIC 52 (typical brand minimum is STC 50 / IIC 45) and 1-hour fire-rated assemblies at Type IIA, tested under the same protocols behind our Intertek loadbearing steel stud panel fire test to ISO 3008-1.
Request the assembly documentation pack, acoustic test reports, fire test certificates, and steel mill certificates for your project’s jurisdiction. Ask us for the documentation set and we will send it before you commit to a design.
Brand standards are not a marketing claim, they are a document set. A franchisor’s technical services team will ask for specific evidence, and a programme that cannot produce it stalls at the review stage regardless of how good the building is. The matrix below lists what a select-service and upper-midscale brand typically requests, and what we hold on file per module.
| Brand requirement | What is submitted | When it is issued | Evidence that decides the claim |
|---|
| Guest room dimensions and clearances | Dimensioned room drawings per key type | Design development | Dimensional check against the prototype drawing set |
| Acoustic separation between keys | Assembly build-up and lab test data | Design development | STC / IIC test report, not a calculated estimate |
| Fire separation and egress | Compartmentation drawings and door schedules | Permit set | Third-party fire test certification per assembly |
| Bathroom finishes and waterproofing | Finish schedule and wet-area detail | Design development | Factory flood test record per wet module |
| Corridor and public area finishes | Palette matching the brand standard book | Design development | Physical sample board sign-off |
| FF&E coordination | Blocking and backing drawings | Pre-fabrication | FF&E contractor written acceptance |
| Accessibility compliance | Accessible unit layouts and hardware spec | Permit set | Accessibility consultant review letter |
| Energy and envelope performance | Assembly U-values and air-tightness approach | Permit set | Code compliance calculation for the project jurisdiction |
Structural Basis: What the Modules Are Actually Built From
Hotel modules in the MODURA network run on two structural platforms, and the choice is driven by storey count and seismic category rather than by cost alone:
- Light gauge steel (LGS) framing, ICC-ES ESR-5348 evaluated system, compliant with IBC/IRC 2021 plus the California and Los Angeles supplements. This is the platform to specify for seismically active US markets; our seismic design guide covers the ductile detailing requirements in detail.
- Q355B structural steel . Hot-rolled frames for volumetric and hybrid builds, supplied with full mill certificates and weld traceability. Verified by SGS chemical composition analysis and covered by an SGS CPR certificate for EN 14350 light gauge steel framing.
Both platforms come out of production lines holding ISO 9001, ISO 14001 and ISO 45001 certification, with documented inspection gates at every workstation and records traceable to the module serial number. That traceability is what allows a modular hotel to pass a brand’s technical services review without re-opening closed walls.
Recent Reference: Soledad, California
Our container-module line delivered the Soledad, California interim housing community in 2026 . A project that exercised exactly the code path a California hotel would need: US jurisdiction, California amendments, permanent modular line production, and documented handover. Container module production runs across six production bases in China, with a permanent modular line added in 2025 specifically for US permanent-occupancy projects.
Programme Comparison: 150-Key Select Service
| Milestone | Modular | Conventional |
|---|
| Design & brand approval | Month 0–3 | Month 0–4 |
| Foundation, site & utilities | Month 2–6 (parallel to factory) | Month 4–9 |
| Module fabrication | Month 3–9 (60–75% complete on dispatch) | n/a |
| Superstructure on site | Month 9–11 | Month 9–17 |
| Fit-out, commissioning, brand sign-off | Month 10–13 | Month 17–24 |
| First room revenue | Month 13–15 | Month 24–28 |
The overlap between site works and factory fabrication is the entire mechanism. Because the module production schedule runs independently of weather and of site readiness, a delayed foundation does not stop the factory, it only delays erection, and the finished modules queue in the yard rather than accumulating site standing time.
How to Verify a Hotel Programme Before You Sign
Every item below can be completed from your desk. None of them require flying to a factory, and together they separate a programme that will hold its dates from one that will not.
| # | Check | What you are looking for | Red flag if |
|---|
| 1 | Match the certificate holder to the factory address | ISO 9001 and structural certification naming the production site | The certificate names a different address or a trading name only |
| 2 | Ask for a factory witness test schedule | A dated hold-point list you are invited to attend | Testing is described but never scheduled |
| 3 | Request the serial-number traceability sample | One real module record: fabrication, inspection, sign-off | Traceability is promised as a future system |
| 4 | Confirm the prototype compliance matrix is signed | A matrix mapped line-by-line to your brand standard | The response is a brochure, not a matrix |
| 5 | Check the transport route survey | A permitted-route study for your specific site access | Logistics are quoted per module without a route survey |
| 6 | Read the risk-transfer clause against the delivery point | Bill of lading language matching the contract | Transit risk is not allocated in writing |
Items 3 and 5 are the ones that separate a real volumetric programme from a panelised one wearing the same vocabulary. Serial traceability implies a controlled production line. A route survey implies the modules have actually been moved at the size you are being quoted. Our bid comparison guide explains how to score competing proposals on exactly these points, and the fire safety guide covers what the certification evidence should contain.
Questions We Are Asked Before Every Hotel Contract
- Can you hit our brand’s prototype? Yes. We build to Hilton, Marriott, IHG and Accor prototype standards and have taken programmes through technical services review. Non-prototype and soft-brand collections are handled as custom modules.
- What about a mid-rise urban site with no laydown area? Volumetric modules are craned directly from the truck into position, so site storage demand is measured in hours rather than weeks. See urban infill delivery for the logistics pattern.
- Who carries the warranty on a factory-built room? Structure and envelope are warranted under a single contract; the module serial number ties each unit to its fabrication and inspection record. Our insurance and risk guide explains how that affects premiums and liability allocation.
- Can we phase the build? Phasing is one of modular’s structural advantages. A 300-key property can open 150 keys, begin trading, and add the balance from the same production line. Our financing guide covers how phased delivery changes the loan structure.
- What is the realistic saving against site-built? On a 150-key select-service property the programme saving is measured in months of revenue, not in construction cost per square foot, and those are not the same number. Our cost per square foot guide separates the two so you can put the right figure in the pro forma.
- Who is responsible if a module arrives damaged? Risk transfers at the delivery point named in the contract, and the serial number on the module is what makes the claim traceable to a specific fabrication record. See the responsibility table above for where that line sits.
- Do you deliver the FF&E and the operator handover? We deliver the building to a defined completion standard. FF&E installation and operator training sit with the developer’s team, and the interface is fixed at design development so the two workstreams do not collide on site. Our programme timeline article shows where that interface falls.
