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.


 

Aquinas College Forum
Aquinas College Forum

 

This project was entered in the LSAA 2007 Design Awards (#3197) "Medium Fabric Structures"

Entrant: Tattersall Engineering

Client: Aquinas College / J A Dodd     Architect: Designinc Adelaide (Geof Naim)
Structural Engineer: Tattersall Engineering (See SEMF 2015)
Specialist Consultant(s): Wade Consultants     Builder: Tecraft Pty Ltd
Fabricator(s): Horizon Sailmakers / C E Bartlett, Riband (Steel), A Noble & Son (Cables)

Application and Function(s) of Project:

The structure is a pivotal element in an $8m redevelopment of the main Aquinas College campus, which comprised a new library, Year 9 centre, canteen and arts centre as well as refurbishment of the old library as an IT, arts and careers centre. The Forum structure links and protects all the adjoining buildings, proving a substantial undercover area in the middle of the school which serves as a protected function centre, meals and play area, incorporates a stage with a protected auditorium area, and links with the existing gymnasium and sports centre building.

Green School Pods, New Plymouth, NZ
2374 Green School Pods - New Plymouth, NZ

LSAA 2022 Plaques 0010

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.

COSTS

Design – 12%   Fabric – 6%   Fabrication – 6%     Steel – 50%     Extrusion etc – 4%  Installation – 22%

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.

Knox Grammar School
Knox Grammar School Project (2018)

APPLICATION OF PROJECT:

The project was to design and install a unique waterproof shade structure to a Year 11/12 study area at an elite private Grammar School in Sydney.

The area under cover is 760sqm. The space to be shaded was clearly defined and located between the austere 19th century red brick buildings on a second floor flat tiled roof

PROJECT DESCRIPTION:

Beyond a school’s playing fields, exposed concrete surfaces often represented the extent of outdoor space in many schools built a century ago. Knox Grammar was no different.Today the definition of outdoor space is much more exciting and open to design possibilities. For schools with resources, outdoor spaces can be unique, comfortable, multifunctional and aesthetic.
