Replacing a new fabric on a old tensile membrane structure

Replacing the fabric is a complex process that requires qualified professionals fabric specialists. Some of the steps involved in replacing tensile membrane fabric, the process is more streamlined and focuses on the fabric itself, not significant structural modifications or engineering aspect of the old tensile membrane structure. Here’s a breakdown of the typical steps for fabric replacement. The focus is on replacing the fabric, not rebuilding the entire structure.:

Evaluation and Planning:

  1. Inspection and Assessment: Specializing in tensile membrane structures will thoroughly inspect the existing structure. This includes the fabric, cables, and support structures. They will assess the condition of the fabric, identify the reason for replacement, and ensure the remaining structure is sound for a new fabric installation.
  2. New Fabric Selection: A new fabric based on the structure’s design, location, wind load requirements, and desired lifespan. Factors like fire resistance, UV resistance, and weight will also be considered.
  3. Engineering Analysis: The engineer might perform additional calculations to ensure the new fabric is compatible with the existing structure and can withstand the expected loads. They likely won’t need to design a completely unless there are significant issues with the existing one. Design and engineering new secondary structure needs significant upgrades to support the new fabric.
  4. Project Planning: A detailed plan will be created outlining the replacement process, including scheduling, access requirements, safety measures, and disposal of the old fabric (if possible).

Replacement Process:

  1. Preparation: The area around the structure will be cleared and secured. Depending on the size and complexity, scaffolding or other access platforms might be needed.
  2. Removal of Old Fabric: The existing fabric panels will be carefully removed, following a specific sequence to maintain structural stability. Depending on the fabric condition and local regulations, it might be possible to recycle some of the material.
  3. Survey the tensile membrane structure. Resurvey New Position: Unless there’s a major change in the fabric design that alters the structure’s position significantly..
  4. Cleaning and Inspection of Supporting Structure: The underlying main support structure. To introduce new secondary structure to receive the new fabric connection. All cables, bolts and nuts, accessories and anchorages will be new. Minor repairs might be needed for main structure, but extensive modifications to the secondary structure are typically required for fabric replacement due to different specialist contractor.
  5. Welding New Secondary Structure: Extensive welding on the secondary structure for fabric replacement. Minor repairs might be needed.
  6. Painting: Painting the entire structure might be done for aesthetic reasons, but it’s not essential for fabric replacement.
  7. New Fabric Installation: The new fabric panels, fabricated according to the approved design and pre-tensioned if necessary, will be carefully installed onto the structure.
  8. Tensioning and Adjustment: The new fabric will be tensioned to achieve the desired shape .
  9. Quality Control and Inspection: After installation, the entire structure will be rigorously inspected by to ensure proper tension, seam integrity, and overall functionality
  10. By involving the right tensile membrane specialist and following a proper plan, you can ensure a successful and safe tensile membrane fabric replacement project.
