Key Structural Considerations
1. Room Size & Grid Alignment
a. Ensure room dimensions align with structural and M&E planning.
b. A standard 4-star hotel room is typically 30m² (4m x 7.5m).
2. Vertical Service Well Design
Must be planned in coordination with the Mechanical & Electrical Engineer.
Ideally designed during the first meeting to prevent costly delays later.
3. Floor Structural Grids & Optimization
a. Economical grid spacing: Generally, 5m to 6m, even in earthquake zones (with additional spiral steel reinforcement for columns).
b. Car park grids: Typically, 8m to 9m, allowing for three cars between columns, with alternating rows serving as driveways.
c. Low-rise hotels (without underground parking): A common structure uses 4m x 6m grids.
d. Room & corridor alignment: Two 7.5m rooms plus a 2m-wide corridor results in a 17m span, which can be adjusted for optimal column placement.
e. When grid mismatches occur, a transfer beam may be necessary to support new grids or reinforced walls above. If required, utilize the empty spaces between transfer beams for storage or staff accommodations.
4. Air Handling Unit (AHU) Room Sizing
This space is often overprovided, leading to inefficiencies.
Identify AHU size early in the design and allocate space efficiently, ensuring doors allow for proper service access.
5. Car Park Placement
a. Above-ground parking significantly reduces construction costs and shortens build time.
b. Basement parking is expensive and extends construction timelines—should only be considered if absolutely necessary.
Final Thoughts
Structural planning plays a crucial role in both construction cost efficiency and long-term operational success. By aligning grids, optimizing space usage, and minimizing unnecessary expenses, we can significantly enhance the hotel’s profitability and functionality.
