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 List of Medium Structures is in order of most recently modified article first:

Shore School Pool Hall Skylight (DA 2022 Entry by MakMax)

LSAA 2022 Plaques 0006
APPLICATION OF PROJECT
:      

ETFE 600 sqm Skylight over an indoor swimming pool

PROJECT DESCRIPTION:

The Shore Physical Education Centre (SPEC) was built to deliver a suite of new flexible learning spaces including a multi-purpose sports complex and an indoor swimming pool. The 16 pillow, 3-layer ETFE skylights were a key part of the indoor swimming pool roof, designed to fill the indoor aquatic centre with natural lighting, while also providing a modern, highly aesthetic architectural feature to the roof.

DESIGN / FABRICATION / INSTALLATION BRIEF

The ETFE skylights located over the indoor swimming pool in the new Shore Physical Education Centre (SPEC) were required to interface with the surrounding Kingspan insulated roof system. We worked closely with the project Architect, Structural Engineer and Builder to develop design details that allowed the two elements to seamlessly connect.

Hiding of ductwork and the air supply plenum was important to the overall finish and as part of our value engineering approach to design, we proposed unique design touches, such as painting the air supply lines to match the internal fascia and keeping the ductwork hidden adjacent to structural elements in order to keep the premium-quality project finish required by the project brief.

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.

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

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.

DESIGN FABRICATION INSTALLATION BRIEF

The Kina building at Green School New Zealand was conceived as a groundbreaking educational facility, designed to embody sustainable and innovative principles. The client’s vision was for a building that would integrate biophilic design with neuroarchitecture, enhancing both cognitive function and emotional well-being. The challenge was to create a structure that not only supported Green School’s commitment to holistic education and environmental stewardship but also reflected a deep connection to nature.

In addressing the design brief, Fabric Structures focused on several key aspects. The project demanded the use of cutting-edge fabric materials that would contribute to both the aesthetic and functional goals of the building.

PROJECT DESCRIPTION

Close to completing the tensile membrane roof at Metricon Stadium, our client engaged MakMax to cover a smaller outdoor area. This project was a simple solution to shade and weather protection with a twist. Considerations for maximum ground space and design constraints made this project far more interesting.

Our brief for this project outlined a need for a large covered area for common use. Specifics included limited space for footings and design considerations to match the structure’s surroundings. The structure also needed to compliment the design of the stadium roof, MakMax engineers and architects Populous came up with a simple looking yet highly complex shape.

Outdoor concert theatre at Jacobs Park

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.
