Bottom Line: When sourcing prefabricated accommodation for your resort project, always verify factory capability, material specifications, structural ratings, export experience, warranty terms and total cost of ownership before placing an order. The 15 questions in this guide will help you compare suppliers objectively, avoid hidden costs, and select a manufacturer that can deliver on quality, timeline and long-term support – not just the lowest upfront price.

Questions About Factory & Capability

Short answer: Start by confirming production capacity, direct factory status and relevant project experience to avoid trading companies and middlemen.

1. Are you a direct manufacturer or a trading company? Can we arrange a factory visit or live video tour?

2. What is your monthly production capacity, and what is your current lead time for orders of our size?

3. How many similar projects have you completed in our country or region? Can you provide references?

4. What certifications do your products hold, and do you provide documentation for local building permits?

5. How long have you been producing prefabricated buildings specifically for the hospitality and resort sector?

Questions About Materials, Quality & Structure

Short answer: Dig into material specifications, structural ratings and warranty coverage – these are where low-price suppliers most often cut corners.

6. What is the exact wall structure, insulation thickness and insulation material R-value?

7. What wind speed and seismic level is the structure designed to withstand for our location?

8. What anti-corrosion treatment is applied to the steel frame, and what is the expected service life?

9. What brand and grade of interior materials, fixtures and sanitaryware are included in the standard package?

10. What warranty do you offer on structure, waterproofing and finishes, and what does it actually cover?

Questions About Delivery, Installation & Total Cost

Short answer: Always clarify what is included in the quoted price, what additional costs you will incur, and who is responsible for each step of delivery and installation.

11. Does the quoted price include packaging, sea freight, insurance and customs documentation?

12. Is foundation design included? Do you provide on-site installation supervision or a full installation team?

13. What utilities and site preparation work are our responsibility before installation begins?

14. What is the exact production lead time, shipping duration and total estimated project timeline?

15. What after-sales support, spare parts supply and maintenance service do you provide after handover?

How to Evaluate the Answers You Receive

Short answer: Look for specificity, evidence and transparency. Vague promises, refusal to share references and prices that seem too good to be true are all red flags.

A reliable manufacturer will answer each question with specific numbers, document names and concrete examples. They will volunteer photos, videos and project references you can verify. They will also be upfront about what is not included and what costs you will need to budget for locally. Be especially cautious of suppliers who quote significantly lower prices but cannot clearly explain material specifications or provide structural calculations. In prefab construction, hidden quality problems become very expensive to fix after delivery, so choosing the right partner based on total value is always smarter than choosing based on lowest initial price.
