On-Site Measurement and Detailed Design for Hotel Fixed Furniture

Hotel fixed furniture — built-in joinery integrated with walls, floors, and ceilings — must fit the actual site perfectly. Unlike movable furniture, it cannot rely on architectural drawings alone. Detail designers must measure on site, produce production drawings, and obtain client sign-off before manufacturing begins.

I. Why Fixed Furniture Needs On-Site Measurement

"Aren't dimensions already on the drawings?" The answer is clear: civil construction has tolerances, and drawings never match the site exactly.

Key sources of deviation:

• Walls not plumb: Masonry walls often have 5–15mm verticality deviations.
• Floors not level: Room floors can have 3–8mm height variations.
• Ceiling height deviations: Suspended ceilings often differ by 5–10mm.
• Corners not square: Wall corners are not always 90 degrees.
• MEP point offsets: Switch and socket positions frequently shift.

Skipping on-site measurement almost always leads to fit problems, gaps, and misaligned cutouts — requiring on-site patching or factory rework.

II. The Measurement Process

Ronghetai's detail team (15 fixed + 3 movable furniture designers) follows a standard "initial survey → re-measurement → key point recording" process.

1. Initial Survey

Before hard finishes begin, the detail designer assesses structural dimensions, beam and column locations, door openings, and overall deviation from drawings. The goal is to identify major structural deviations early, giving the design team time to adjust.

2. Re-Measurement

After wall plastering, floor screeding, and ceiling suspension are complete, the detail designer returns for millimeter-precision re-measurement. This is the critical measurement — production drawings are based on this data.

3. Key Point Recording

Beyond dimensions, the detailer records special conditions: protruding beams, concealed pipes, large wall deviations, and MEP cutout requirements. All are marked on the drawings.

III. What Detailed Drawings Include

After measurement, the designer produces:

• Floor plans and elevation drawings with dimensions and materials
• Detail sections and trim details for critical junctions
• Bill of Materials (BOM) listing all panels, veneers, hardware
• MEP cutout drawings with precise opening locations
• Installation diagrams showing assembly sequence

This set serves as both the production basis and the client confirmation document.

IV. Drawing Review and Sign-Off

Drawings go through: internal review → client submission → review meeting → revision → sign-off.

Sign-off is essential before production. Drawings without authorized signature must never enter production — this protects both the client and the factory.

V. Production Ordering After Confirmation

After sign-off, four key principles apply:

1. Lock dimensions: Confirmed sizes do not change. Any modification requires a formal change order with written client confirmation.
2. Phased production: Deliver by floor or zone to ease factory capacity and site storage pressure.
3. Change management: All changes must be documented — scope, reason, cost/schedule impact, and signatures from both parties.
4. Mock-up first: Produce one mock-up room set before full production to confirm results on site.
