2. Excavation and Foundation Construction

Foundations are constructed according to the engineering specifications. This may involve excavation, formwork, reinforcement placement, and concrete pouring. The type of foundation varies depending on site conditions and structural requirements, ranging from simple concrete footings to complex deep foundation systems.

3. Anchor Bolt Installation

Anchor bolts are embedded in the foundations at precise locations to ensure proper alignment of structural components. These bolts are critical for securing the support structure and must be positioned accurately to avoid installation issues later.

4. Utility Relocation or Protection

If necessary, existing utilities are relocated or protected to prevent damage during installation. This may involve coordination with utility companies and implementation of protective measures to ensure safety and service continuity.

Structural Frame Installation

With foundations complete and cured, we begin installing the structural frame that will support the membrane:

1. Erection of Support Structures

Primary support elements such as masts, arches, or frames are erected and secured to the foundations. This process typically requires cranes or other lifting equipment, and our team follows strict safety protocols to ensure a safe and efficient installation.

2. Secondary Structural Elements

Secondary structural elements, such as purlins, edge cables, and support frames, are installed to create the framework that will support the membrane. These elements are positioned according to the design specifications and secured with appropriate connections.

3. Cable and Tensioning System Installation

Cables and tensioning systems are installed according to the engineering design. This includes positioning cables, installing fittings, and setting up tensioning devices that will be used to apply the appropriate tension to the membrane during installation.

4. Quality Checks and Adjustments

After installing the structural frame, our team conducts thorough quality checks to ensure all components are properly positioned and secured. Any necessary adjustments are made before proceeding with membrane installation.

Membrane Installation

The installation of the membrane is a critical phase that requires skill and precision:

1. Membrane Unfolding and Positioning

The fabricated membrane is carefully unfolded and positioned on the structural frame. This process requires coordination among team members to ensure the membrane is oriented correctly and not damaged during handling.

2. Initial Attachment

The membrane is initially attached to the structural frame at key points to secure it in position. This typically involves clamping or bolting the membrane edge to the support structure at predetermined locations.

3. Progressive Tensioning

The membrane is progressively tensioned using the installed tensioning systems. This is a delicate process that requires careful monitoring to ensure even tension distribution and prevent over-stressing of the material. Our technicians use specialized tools and techniques to achieve the optimal tension specified in the design.

4. Edge Detailing and Finishing

Once the membrane is properly tensioned, edge details and finishing elements are installed. This includes edge cables, clamping systems, and protective covers that provide a finished appearance and ensure the long-term durability of the membrane.
