Technical Challenges and Preparatory Work for the Mountain-Top Hotel Project (Tent Hotel, Clubhouse, and Art Center)

I. Technical Challenges

1. Complex Terrain

   • The project is located at the mountain top, where access roads are narrow and steep, making transportation of large materials and equipment difficult.

   • Strong winds at the summit increase the risks of hoisting and installation of glass curtain wall panels and aluminum cladding.

2. Curtain Wall System Complexity

   • Large-scale glass curtain walls must meet strict requirements for safety, wind resistance, and condensation prevention.

   • The aluminum panels include curved and double-curved surfaces, requiring high-precision fabrication and installation based on 3D modeling and accurate field layout.

3. Structural Integration

   • The curtain wall must seamlessly connect with steel structures, roofing, and waterproofing systems. Joint design must address drainage, waterproofing, and thermal expansion.

   • At the tent hotel, membrane structures transition into curtain walls and cladding; flexible connections are required to prevent cracking and leakage.

4. Adverse Construction Conditions

   • Large daily temperature differences and frequent rain, snow, and strong winds at the mountain site affect sealant curing and panel hoisting stability.

   • High-altitude work carries significant safety risks, requiring strict control of scaffolding, platforms, and installation procedures.

II. Crane Installation and Preparatory Work

1. Equipment Setup

   • Crawler cranes or truck cranes should be selected based on terrain, with temporary platforms reinforced to ensure load-bearing capacity and leveling.

   • Equipment transportation may require road reinforcement or segmented delivery, with smaller cranes used for secondary lifting if necessary.

2. Surveying and Layout

   • Total stations and laser scanning equipment will establish a high-precision 3D coordinate control network.

   • BIM models will guide the layout of curtain wall mullions and aluminum cladding, ensuring accuracy during on-site marking.

3. Material Transportation and Storage

   • Glass panels and aluminum cladding must be transported in batches, with protected temporary storage zones established on site to minimize damage.

   • Oversized glass panels require special wooden packaging, with lifting points pre-installed on components for safe hoisting.

4. Hoisting Procedure Preparation

   • A detailed lifting plan must be developed, covering lifting point arrangements, rigging specifications, and wind speed safety limits.

   • Adequate crane swing radius and temporary assembly zones must be reserved at the summit to avoid interference from concurrent operations.

5. Safety and Emergency Plans

   • Workers engaged in high-altitude operations must undergo specialized safety training and be equipped with fall-arrest systems.

   • Emergency protocols should be established for strong winds, heavy rain, or lightning, ensuring safety of both equipment and personnel.
