Medium Fabric Structures

In terms of our LSAA Design Awards, a Medium sized Fabric Structure, or tensioned membrane structure, would have a surface area of between 250 and 1000 sqm.

Tensioned fabric or membrane structures of this size are often of one geometric form such as a conical structure with a central bale ring attached to a mast or tied down. The perimeter could be a series of edge cables, trusses or beams. If multiple units are used they the final structure may fall into the "large" category.

Other forms could be panels with internal diagonal arches, crossed arches, barrel vaults with intermediate valley cables.


The following articles are in random order whilst the (separate) List of Medium Structures is in order of most recently modified article first. As of May 2025 approximately 42 articles are available.

PROJECT NAME:    Trinity Point Tension Membrane Structure

 MLF22Trinity00158

PROJECT DESCRIPTION:

This project was located in the Central Coast of New South Wales. It is a unique tension membrane structure designed to create a wow factor for a new restaurant. It was not only designed to create a visual impact, but also to provide extensive coverage to maximise the outdoor dining area table space and increase revenue for the restaurant.

We were approach by the client to Bring a design vision to life. The initial vision of the client to produce this project had come to a halt, then we were asked to come on board to use our expertise to bring this project to fruition and create a visual impact that would create global publicity for the restaurant.

APPLICATION OF PROJECT:      

3 Pod like classrooms at Green School NZ

PROJECT DESCRIPTION:

To provide an outer skin from a material that can be recycled if/when replaced and also blends into environment.  Wastage of non-recyclable materials to be kept to a minimum.

Also to provide the support frame to take the PVC membrane.

DESIGN / FABRICATION / INSTALLATION BRIEF

It was requested by the architect that we would supply a membrane solution for three-pod like classrooms for Green School New Zealand, to function as an aesthetic cladding and to create a ventilated thermal barrier to reduce a “heat soak effect” into the building.  This was to complement the “green” label for the structure, reducing running costs and adding an organic look.

STRUCTURAL SYSTEMS

The overall complexity of the project was caused by the intriguing shape and challenging geometry, also the construction materials which were proposed.  

The glulam timber beams implicated large tolerances on site, which required the steel components to be customized to match each of the three structures.

3d- digitizing of the design assisted by the construction of the tension-membranes.  The high stretch of the fabric paired with the shape of the structures added the additional complexity of staged tensioning over multiple weeks.

MATERIALS

Mehler – Valmex Lodge de lux FR – 580gsm PVC

FABRICATION

The fabrication had complex geometry as the fabric had a high weft compensation which meant minimum tolerance to allow for the correct fit. The geometry for the fabric started with digital site measure using a Proliner first, followed by computer controlled cutting many checks and keder length dimensions to ensure accurate final panel size.

A similar process was used for the steel fabrication given the challenging geometry.

COLLABORATION, CONSTRUCTION AND MAINTENANCE

Being a bespoke membrane structure Cleland Construction Limited had to overcome the different approach from standard construction methodology and Fabric Structures & Cleland Construction work well to get the desired effect. This was mainly around a realization that fabrication off a 3D model was not going to create a successful outcome, therefore a proliner measure once the steel had been installed, then fabrication (with multiple QA check s) was agreed.

PROJECT NAME:

Tumbalong Green Amphitheatre Roof

APPLICATION OF PROJECT:

Public Amphitheatre roof covering

 

PROJECT DESCRIPTION:

Creating a showpiece architectural structure in Darling Harbour, the Tumbalong Green Amphitheatre is a remarkable marriage of beautiful elements and engineering expertise. Exemplifying the stunning possibilities of lightweight structure design, the soundshell curves up and over the stage, appearing to almost float over the performance space and encourages sound to wash over the audience like a breaking wave.

An example of architectural design meets functionality, the combination of Cross Laminated Timber (CLT) structural elements supporting a 1000 square metre PVC membrane have created a lightweight, and visually appealing public amphitheatre roof.

APPLICATION: Public space & market canopy

As part of a major revitalisation and landscaping project for the Whangarei City Town Basin, the local council approached FSS to design a permanent canopy structure for the recently closed John Street bridge.

The John Street Bridge was one of two original road bridges connecting the Northern and Southern shores of the upper Whangarei harbour and forms part of the City Town Basin.

The Rady Shell Concert Venue Description

The Rady Shell in San Diego Symphony’s new bay side venue is the first permanent year-round bay side concert venue in the nation operated by the Symphony Orchestra. The Rady Shell can accommodate audiences of 3,500 – 8,000 per concert and up to 10,000 for special events.

Fabritecture was engaged for the technical design and fabrication of the Rady Shell performance structure and surrounding pavilion structures. The Shell itself comprises a rolled steel frame and PTFE cladding. The entire structure is approximately 236,000lbs (107,000kgs or 107 tonnes).

The stage accommodates an orchestra size of up to 150 musicians and choir with a front of stage width of 32m and depth of 20m. The roof cantilevers 15m from the front of the stage and can carry a payload of up to 50T. The stage incorporates state of the art constellation sound system designed and engineered by Meyer Sound. This system provides an exemplary sound environment on stage for the musicians, whilst also providing the technical flexibility required for a variety of other performances

The overall project includes development of a range of public facilities, including restrooms, fitness facilities & rest areas. Food pavilions and a small stage are also part of the master design plan.

PROJECT DESCRIPTION

This project was essentially a weather cover over a public space. During discussions with our sales team at the tendering stage it was clear that the project also had an element of environmental consideration. For this reason we developed a custom design that worked to these constraints.

The purpose according to builders was to create an inviting public recreation area. The architects specified a tensile membrane roof in order to cover the area while allowing natural light to enter the space.
