Basic Information and Market Adaptability of Two-Story Warehouse Project in US Virgin Islands

 

 

 

This project is a customized two-story warehouse designed for clients in the US Virgin Islands, adopting the mature CBC steel structure system matched with EPS sandwich panel wall and roof panel enclosure system. The overall external dimension of the warehouse is 160 feet (length) × 60 feet (width) × 27 feet (total height). The whole building is divided into 3 independent functional units, with a single unit length of 53.5 feet, and 50mm thick EPS sandwich panels are used as partition walls between each unit to realize independent space division.

 

In terms of storey height design, the first floor of each unit has a clear height of 14 feet, and the second floor has a clear height of 13 feet, which meets the conventional storage and cargo handling height requirements of industrial warehouses. Each independent unit is equipped with complete supporting facilities, including one electric roller shutter door with a size of 12ft (width) × 14ft (height) for large cargo access, one standard steel door for personnel daily access, and one professional steel structure staircase as the fixed vertical traffic passage connecting the first and second floors. The overall functional layout is reasonable, which can meet the independent operation and use needs of a single unit, and also support the overall unified scheduling of the three units.

 

 

 

The project adopts a rigid and stable CBC steel frame structure system, with standardized and optimized section design of main load-bearing components to ensure structural safety and stability under complex environmental and load conditions. The specific component section parameters are clear: the main steel column adopts H-section steel with a specification of 450*250*6*10mm; the main roof and wall frame steel beam adopts variable cross-section H-section steel with a specification of 700~500*200*6*8mm; the floor bearing beam of the second floor adopts H-section steel with a specification of 500*250*8*10mm. The hierarchical and differentiated section design of structural components realizes the optimal matching of force-bearing capacity and material consumption.

 

In terms of load design, the project complies with local industrial building design standards in the US Virgin Islands, with a designed wind pressure of 1.44KN/m², which can resist strong wind weather in coastal island areas effectively. For floor load-bearing, the second floor adopts a composite force-bearing system of CBC steel frame + floor slab + cast-in-place concrete, with a designed floor live load of 5.37KN/m² and a dead load of 4.00KN/m². The 120mm thick on-site cast-in-place concrete layer greatly improves the overall rigidity, flatness and bearing uniformity of the floor structure, avoiding local deformation and damage caused by long-term cargo stacking and mechanical handling, and ensuring the long-term safe service of the warehouse structure.

 

 

 

The project's main materials are divided into three core categories: steel structure main components, enclosure and partition materials, and floor concrete materials, with standardized and economical material matching. First, the steel structure system covers all main load-bearing and auxiliary force-bearing components, including main steel columns, primary and secondary steel beams, floor steel frames, steel structure staircases and door frame steel accessories. All steel components adopt high-quality H-section steel with precise section specifications, featuring high strength, good toughness and stable mechanical performance, and all components are prefabricated in the factory with high dimensional accuracy.

 

Second, the enclosure and partition system adopts EPS sandwich panels uniformly. The outer wall and roof of the whole warehouse use customized EPS sandwich panels matching the CBC steel structure system, and the internal unit partition walls adopt 50mm thick EPS sandwich panels. This kind of panel integrates heat insulation, heat preservation, wind resistance and sealing performance, and has the advantages of light weight and fast installation. Third, the floor structure of the second floor adopts on-site cast-in-place concrete with a thickness of 120mm, which is compounded with the pre-installed CBC steel floor frame to form a reliable composite floor system.

 

In terms of material consumption characteristics, the CBC steel structure system optimizes the section design, avoiding the waste of traditional steel structure materials; the lightweight EPS sandwich panels reduce the self-weight of the building structure, thereby reducing the bearing pressure of the main steel frame and foundation, and further controlling the overall material consumption and engineering cost. The overall material matching realizes the balance of safety, durability and economy.

 

 

 

First of all, it has outstanding structural safety and environmental adaptability. The CBC standardized steel frame structure has high overall rigidity and strong wind resistance, which can adapt to the strong wind, humid and rainy climatic conditions of island and coastal areas. The customized wind pressure and floor load design can meet the strict building safety standards of overseas regional markets. The composite floor system of steel frame + cast-in-place concrete solves the problem of insufficient rigidity of traditional light steel floors and improves the stability of heavy-load storage.

 

Secondly, the construction efficiency is extremely high. All steel structure components are prefabricated and processed in the factory with standardized sizes, which only needs on-site assembly and fixation, greatly shortening the on-site construction cycle. The EPS sandwich panel is an integrated finished enclosure material, which does not need secondary wall and roof decoration, realizing one-time forming of enclosure and heat preservation. Compared with traditional concrete frame and brick wall warehouses, the construction period can be shortened by more than 40%.

 

In addition, the system has excellent economic and functional advantages. The lightweight design of steel structure and EPS panels reduces the foundation construction cost and overall building self-weight; the EPS sandwich panel has good heat insulation and heat preservation performance, which can effectively reduce the later operation energy consumption of the warehouse. At the same time, the modular unit design is flexible, which can realize independent use or combined use of multiple units, meeting the diversified storage needs of customers. The standardized steel components also facilitate later maintenance, replacement and expansion of the building.

 

 

 

Applicability for the Philippines Market: The Philippines is a coastal island country with frequent typhoons and humid and hot climate throughout the year. The project's designed wind pressure of 1.44KN/m² fully adapts to the local typhoon weather resistance requirements. The EPS sandwich panel enclosure system has good moisture-proof, heat insulation and anti-corrosion performance, which can effectively avoid building mildew, corrosion and structural aging caused by long-term high humidity. In addition, the local industrial infrastructure construction demand in the Philippines is large, and the CBC modular rapid construction system can meet the market's demand for short-cycle and low-cost warehouse construction, with extremely high market matching degree.

 

Applicability for the Chile Market: Chile has a diverse climate, with coastal strong wind areas and high-altitude temperature difference areas. The CBC steel structure has high structural stability and strong wind and pressure resistance, which can adapt to complex local climatic conditions. The 5.37KN/m² high floor live load design meets the storage needs of local industrial goods, mineral products and other heavy goods. At the same time, Chile's industrial warehouse market has high requirements for building durability and standardized design, and the standardized prefabricated CBC steel structure system conforms to local industrial building specifications, with convenient later maintenance and strong market promotion adaptability.

 

 

Applicability for the Indonesia Market: Indonesia is a tropical archipelago country with high temperature, high humidity and frequent strong winds, and local warehouses are prone to corrosion and heat accumulation. The EPS sandwich panel adopted in the project has excellent heat insulation and anti-corrosion properties, which can effectively reduce the internal temperature of the warehouse and protect stored goods. The CBC steel structure has been optimized for anti-corrosion and wind resistance, adapting to the local harsh marine climate. In addition, Indonesia has a huge demand for small and medium-sized multi-unit warehouses, and the 3-unit independent split design of the project is highly in line with the local market's diversified storage and rental operation needs, with broad application prospects.

 

Applicability for the Papua New Guinea Market: Papua New Guinea has backward local construction infrastructure, scarce traditional building materials and high construction costs. The CBC prefabricated steel structure system has a high degree of factory prefabrication, low dependence on on-site construction conditions and local building materials, and can complete construction efficiently with simple on-site assembly. The lightweight building system reduces the difficulty of foundation construction, adapting to the complex local geological conditions. At the same time, the system has low later maintenance cost and strong durability, which can make up for the shortage of local building maintenance capacity, and is very suitable for industrial warehouse construction in Papua New Guinea and other emerging markets with backward infrastructure.
