Step 1 One
Design Scheme

The first step in bringing your dream project to life is the design phase, where we create detailed architectural blueprints tailored to your needs and vision. These blueprints form the foundation of a successful build, capturing every essential detail from layout to aesthetics.

Once the blueprints are complete, our experienced structural engineer steps in to ensure the design is not only beautiful but also structurally sound. Using industry-leading software like Autodesk Revit and AutoCAD, we analyze and refine the design to meet all safety and engineering standards. This process helps identify any potential issues early, saving you time and money down the line.

Step 2 Two
Steel Structure Frame

In the second step of modular integration construction, the steel structure is precision-manufactured in the factory based on the partitioning of the architectural blueprints. Our engineering team carefully divides the design into individual modules, allowing each section of the building to be fabricated as a self-contained unit.

Using advanced manufacturing techniques and software, we produce steel frames and components for each module under strict quality control standards. This modular approach ensures that every part fits seamlessly together during on-site assembly, improving efficiency, reducing waste, and shortening the overall construction timeline.

Step 3 Three
Insulation & Fireproof Materials

The third step in the modular integration construction process is insulation and fireproofing, a crucial phase that ensures the building meets high standards of energy efficiency, comfort, and safety.

Once the steel modules are fabricated, we apply insulation materials to the walls, roof panels, and other key areas to provide excellent thermal performance and soundproofing. This step helps reduce energy costs, improve indoor comfort, and support sustainable building practices.

At the same time, we carry out fireproofing treatments on all critical materials, including steel structures and wall panels. Using certified fire-resistant coatings and materials, we enhance the building’s safety and compliance with international fire safety standards.

Step 4 Four
Exterior Wall Decorations

The fourth step in the modular integration construction process is the installation of exterior decorations, where we bring the building’s design to life with custom finishes that match the client’s vision.

At this stage, we apply decorative treatments to the exterior walls, giving the structure its final aesthetic look while also enhancing durability and weather resistance. We work closely with clients to select the right materials and finishes to achieve the desired style — whether modern, classic, industrial, or minimalist.

Some popular examples of exterior decorations we offer include:

Aluminum composite panels for a sleek, modern look

Wood or wood-look cladding for a warm, natural appearance

Stone veneer or cultured stone for an elegant, timeless finish

Textured or colored coatings for unique surface effects

Ceramic or porcelain tiles for a high-end, polished facade

Step 5 Five
Interior Decorations

The fifth step in the modular integration construction process is interior decoration and finishing, where we transform the internal space into a comfortable, functional, and beautifully designed environment.

At this stage, we install a range of high-quality interior materials that enhance both aesthetics and usability. This includes:

Interior wall panels (available in wood, PVC, or decorative finishes)

Flooring systems such as laminate, vinyl, tile, or engineered wood

Ceiling treatments including suspended ceilings or decorative panels

Interior doors and trim work for a polished, complete look

We work with clients to tailor the interior style to their preferences — whether they want a modern, minimalist design or a warm, classic atmosphere. All materials are selected for durability, easy maintenance, and long-term performance.

Step 6 Six
Equipment Installation

The sixth step in the modular integration construction process is the installation of essential equipment, including kitchen cabinets, bathroom fixtures, and other interior elements that complete the functional spaces of the building.

In this phase, we install:

Kitchen cabinets and countertops, ensuring optimal layout and functionality for a stylish and efficient cooking space

Bathroom fixtures including sinks, toilets, showers, bathtubs, and storage solutions

(MEP system) Plumbing and electrical systems are also connected and tested, ensuring everything is in place for operational use

The seventh step in the modular integration construction process is packing and shipping, where we ensure that every module and component is securely prepared for transport to the project site.

Given that the modules can vary in size, we use customized packing solutions, including a large, durable fabric cover that protects the modules from environmental factors during transit. The covers are designed to safeguard the building materials, ensuring they remain in perfect condition until they reach their destination.

Step 8 Eight
On-Site Assembly

The eighth step in the modular integration construction process is the on-site installation, where the pre-fabricated modules are carefully placed into position and stacked to create the structure.

To ensure precise and safe installation, we use a crane with four lines, which allows us to securely lower each module into place. This method guarantees stability and accuracy during the installation process, ensuring each module is perfectly aligned with the others.

Once each module is in position, they are connected with heavy-duty bolts to secure them together, creating a stable and robust structure. These connecting bolts ensure the modules are firmly attached and properly aligned, providing the necessary strength and durability for the entire building. After the modules are stacked and bolted into place, the entire framework of the building is complete.

Using industry-leading software like Autodesk Revit and AutoCAD, we analyze and refine the design to meet all safety and engineering standards. This process helps identify any potential issues early, saving you time and money down the line.

Step 2 Two
Concrete Integral Mold

In concrete modular construction using Ultra High-Performance Concrete (UHPC), the main body of each module is integrally molded as a single, seamless structure. This process ensures high structural integrity and precision from the outset. Once the concrete has cured, the surface is polished and refined by automated robotic systems, achieving a smooth, high-quality finish without the need for extensive onsite work.

Step 3 Three
Partition Wall and Window Installation

Based on the layout design requirements, prefabricated wall panels can be attached to both sides of the core module, functioning as exterior walls or corridor partitions. Openings for doors and windows can be integrated into these panels as needed. Like the core module itself, the prefabricated wall panels feature an insulated core layer, ensuring compliance with insulation and thermal isolation standards.

Step 4 Four
Electricity, Drainage, HVAC Installation (MEP)

In concrete modular construction, electrical, plumbing, drainage, and HVAC systems are strategically integrated during the factory production phase to ensure seamless functionality upon installation. Electrical conduits and junction boxes are embedded within the concrete walls and ceilings of each module, allowing for pre-installed wiring that connects easily on-site. Similarly, plumbing and drainage pipes are cast or channeled into the module’s structural elements, with precise openings and access points aligned to facilitate quick connection between modules and the site’s utility network.

HVAC systems are accommodated through pre-planned duct routes, embedded sleeves, or designated spaces within the module’s structure, enabling easy integration of ventilation, heating, and cooling systems. Depending on the project’s complexity, HVAC units and controls may be partially or fully installed in the factory, reducing on-site labor and installation time. By embedding key MEP (mechanical, electrical, plumbing) components directly into the modules, concrete modular construction achieves faster commissioning, higher quality control, and minimal disruption during final assembly on-site.

Step 5 Five
Interior & Equipment Installation

In concrete modular construction, interior and equipment installation is largely completed within the factory before the modules are delivered to the site. Interior finishes such as wall panels, flooring, ceilings, and built-in cabinetry are installed in a controlled environment, ensuring high quality and consistency.

Step 6 Six
Packing & Shipping

The seventh step in the modular integration construction process is packing and shipping, where we ensure that every module and component is securely prepared for transport to the project site.

Given that the modules can vary in size, we use customized packing solutions, including a large, durable fabric cover that protects the modules from environmental factors during transit. The covers are designed to safeguard the building materials, ensuring they remain in perfect condition until they reach their destination.

Step 7 Seven

Step 2 Two
Framing Machine

In lumber modular construction, the framing process is highly automated, utilizing advanced machinery such as CNC saws, robotic nailers, and precision assembly lines to cut, assemble, and secure structural components with exceptional accuracy. Each piece of lumber is measured and cut by computer-controlled equipment to exact specifications, reducing material waste and ensuring tight tolerances. Automated systems then position and fasten studs, plates, and joists, creating wall, floor, and roof panels or volumetric frames with consistent quality. This machine-driven process not only accelerates production but also enhances structural integrity and minimizes human error, resulting in reliable, factory-built modules ready for finishing and assembly.

Step 3 Three
Module Production

In lumber modular construction, the building envelope is completed efficiently within the factory through a streamlined process. First, exterior sheathing is installed over the wood framing, followed by vapor barriers and insulation placed within the wall cavities to ensure thermal performance and moisture control. Once insulated, the interior is finished with drywall or wood paneling, primed and painted, and outfitted with flooring, cabinetry, doors, and windows, creating a near-complete interior environment.

Meanwhile, mechanical, electrical, and plumbing (MEP) systems are pre-installed inside the modules, including wiring, outlets, switches, plumbing lines, and basic fixtures, allowing for easy connection on-site. Finally, exterior finishes such as siding, cladding, or weatherproof coatings are applied as per the design, providing a fully enclosed, finished module ready for transport and rapid installation at the building site.

Step 4 Four
Packing & Shipping

The seventh step in the modular integration construction process is packing and shipping, where we ensure that every module and component is securely prepared for transport to the project site.

Given that the modules can vary in size, we use customized packing solutions, including a large, durable fabric cover that protects the modules from environmental factors during transit.
