MAJOR CONSTRUCTION

RESEARCH

INFLUENCE- Broadmeadows, Victoria, Australia // Cox Sanderson Ness Fibreglass extruded custom profiles, thermal bridging, gel coating












DESIGN INTENTION

-The Polymer Engineering Centre is a 23, 680 square foot (2200 sq. metres) microcosm of a plastics manufacturing plant, replete with laboratories, meeting rooms, offices, and teaching spaces

-The design attempts to shape a collaborative role between the public community in the area and private users of the building, as well as a shared link between the plastic industry and the education community.

-This building not only advocates for the formal beauty and adaptability of plastic, but also for its environmental qualities.

MATERIALITY

-In this project, the wall material is also the roof material; the exterior moisture barrier is also a light-transmitting skin; the insulation system is also a convection system; few materials or assemblies can perform all of these functions

-The building is a steel skeleton clad in a double layer of translucent corrugated fibreglass.

-The plastic skin provides lightweight solution for thermal bridging and direct heat transmittance while allowing natural lighting throughout most of the building.

-Located in a hot, dry climate, and orientated with its long face toward the hot afternoon sun, this building uses the wall not as a barrier but as a channel for air movement to passively exhaust unwanted hear, simultaneously bringing in optimal daylight and reducting the need for artificial cooling of the interior space.

TECHNICAL

-The primary structural system is a steel frame, composed of tube section columns and custom fabricated trusses to the form the curved roof and north wall.

-Custom fabricated parellel chord trusses span horizontally between vertical trusses located at gridlines. The trusses hold the layers of cladding apart to permit air to circulate vertically in the cavity

-The corrugated fibreglass cladding is an Australian-made product called Cool-lite GC, which provides diffused light and only 23.5 percent total heat transmission due to gel coat technology.

-Corrugated sheeting profiles were installed using the fastening screws together with (32mm) weathertight washers for a secure and waterproof finish

-Santiago, Chile // Felipe Assadi
Multiwall Polycarbonate Sheeting, Transparency


















-It is extremely difficult to find information on Felipe Assadi, his work is only found in exclusive magazines and selected website. I was fortunate to find a magazine where a selected few were found.

DESIGN INTENTION

-This building is a pick-up facility for merchandise that was ordered online or through the mail. The simple program consists of a lobby/ pick-up area, storage space, and restrooms

-The linear floor plan allows for three customers in automobile to simultaneously be served by the three functions; purchasing, payment, and pick-up

-It was designed to appear more than a storage facility. The architect used ways in technology and materiality to create something simplistic to complex

MATERIALITY

-Arauco Express has a unusual reflectance and transmittable characteristics of multi walled polycarbonate sheeting, could be an interesting way to improve the geometric structure.

-It is a simple steel structure with a double skin of wood panels, over which is a multilayered polycarbonate skin, giving the building a luminous presence through its translucent layer.

-Compared to glass, polycarbonate cladding is lighter, less expensive, and is easier to install using simple detailing.

-The buildings appearance changes constantly due to varying daylight conditions, and the reflections of passing vehicles

-Between the wood and polycarbonate are 150 blue-hued fluorescent light to illuminate the building after sundown.

-ARCHITECTS -Sean Godsell (Carter Tucker House)















-Sean Godsell a renowned Australian architect who experiments with a range of materials and concepts

-Fascinated in his work including the Carter Tucker House which the facades are veiled with a system of adjustable louvers which blur the edges of the building and constantly modify its appearance

-This is a conscious attempt to accentuate the buoyancy of intermittent light changes caused by changing light conditions with the system.

-INITIAL SKETCHES

My initial sketches, i began experimenting with different geometric shapes. I wanted the construction to somehow resemble or have inspiration from the theme of the construction.















-MATERIALS

Researching thoroughly into the selected architects materials To start my research i began with Info link sourcing materials and concepts.

-COOL LITE GEL COATING







Installation - Fixing Details

-Ampelite sheeting shall be installed in accordance with Ampelite fixing instructions and with AS/NZS 1562.3:1996, Design and installation of sheet roof and wall cladding

-Please note these additional requirements:Ampelite translucent sheeting matching positive fixed profiles shall be installed using the fastening screws applicable to the main cladding, together with a 32 mm Weatherlok washer.

-This combination gives a secure and weathertight finish. The fixing screws should not be overtightened to an extent that the sheet buckles, allowing water penetration at the seal or sheet overlap.

-Fixing should be made at every crest at both ends of the sheet, and every second crest at intermediate purlins or girts.

-Where Ampelite fibreglass sheeting is in CONTACT WITH SAFETY MESH a Protective Foam Strip (75 mm x 5 mm), or a 70 mm Fibreglass profiled Isolation Strip, should be installed over the safety mesh, to avoid fracturing of the underside of the sheet.

-Where END LAPPING is required a minimum of 300 mm overlap is essential. On profiles such as corrugated, 5-rib or similar, we recommend the use of 25 mm Lap Seal Tape at the top and bottom edges of the purlin. This ensures the strips are concealed.

Clip fixed Decking

-Ampelite sheeting matching clip-fixed deck profiles shall be installed in conjunction with the main cladding and should be side lapped with overlaps on both sides (Ampelite sheets have 2 female laps).

-Fixing of sheets should be carried out in the same manner and practice as those stated for positive fixed profile roofing.

-Wall Cladding Pan fixing is required at each girt, and use of Ampelite grey dome 22 mm weatherseals ensures a weathertight seal.

-Overtightening or flattening the weatherseal must be avoided. Fixing shall occur in every pan at both ends of the sheeting, and every other pan at intermediate girts.
