(2) Key and difficult points of construction:

The first floor lobby and rotating staircase of the project are key quality areas. Due to the fact that the ground of the first floor lobby is a mosaic floor and the rotating staircase is paved with stone, we directly selected the stones from the Fujian Shuitou stone supply market and sent them to a professional stone processing factory in Shanghai for processing. The project department sent professional personnel to the factory for tracking and pre layout during processing to ensure the quality of the stones. The stones were numbered and on-site construction was carried out according to the numbering, During the construction, operators with good stone paving techniques were selected to carry out the construction, ensuring the quality of large area stone mosaic flooring and staircase stone, becoming a highlight of the project.

With the favorable situation in the hotel industry, every investment unit needs to be effectively controlled in terms of decoration time, cost, and environmental protection. During the decoration process, new construction techniques such as off-site processing and on-site installation of wood veneers are also an inevitable trend facing the industry. They effectively adapt to the development and application requirements of new building materials, prevent on-site processing, and reduce environmental pollution caused by on-site paint construction, Simultaneously meeting the requirements of modern design.

(3) The use of new engineering materials and processes

1. The factory production of finished wood veneers has greatly improved the quality of decoration: all equipment and environments in the factory are designed for the production of wood veneers, and the paint effect produced by dust-free paint rooms and infrared paint rooms is incomparable to on-site construction. Customized wood veneer products based on on-site dimensions will fit well with the site, making better use of the on-site space. Factory production adopts standardized and serialized component assembly production processes, which are strictly monitored to ensure stable product quality. The relative humidity in the southern summer is relatively high, so wooden decoration is prone to deformation and swelling. Factory operation effectively solves this problem

2. Application of Chevrolet Plate: The HVAC system and decoration requirements of this project require the use of new material Chevrolet plate for the air supply outlet to replace the traditional aluminum strip air outlet. In addition, the new carving processing technology effectively ensures a simple European style design, and the application of its material completely solves the problems of deformation and aluminum air outlet mismatch caused by temperature changes in the air supply outlet. It is also an innovation in the use of materials in this project. Chevrolet board, also known as PVC expansion sheet and Andy board. PVC is used as the main raw material, added with foaming agent, flame retardant and anti-aging agent, and extruded with special equipment. The application of this new material is mainly in the side air supply outlets of the lobby, the flat air supply outlets of the multi-functional hall and banquet hall, with the aim of effectively ensuring that the air outlets do not deform and achieving a simple European design style.

2、 Exclusive interview (report by the owner's representative)
