Aku adalah binatang jalang yang menghembuskan angin kedinginan. apa pun bisa kita lakukan, biarkan Hayal mu melambung tinggi menikmati sensasi lambda sehingga hayalmu menembus batas, bangun ketika kau mulai lelah akan semua, bakarlah dinding-dinding yang membuatmu tidak mempunyai waktu untuk membuka sensasi Lamda. masih ingatkah kita pernah bercerita tentang puncuk-puncuk lambda di ketinggian 200Hez aku telah menemukan seluk beluk lambda. Mari bersama menembus batas normal, yang akan membuka tabir mimpi menjadi kenyataan. aku lambda yang membagunkan dengan Argumentum ad populum, wujud nyata, ilusi, melayang maya membuka tabir biru menjadi sir Lamda

Case Study: Canberra Olympic Swimming Pool

JK.25071987.
Background:
The Canberra Olympic Swimming Pool development was an ACT Government funded initiative to remove, replace and recycle the existing 22-year-old air-supported membrane enclosure in order to upgrade the look, feel, and functionality of the facility.
Scope of Work:
The replacement structure was required to be a clear-span design with curved roofing in the shape of a dome. PVC tensile fabric with a blue and white colour scheme was specified to match the existing structure design.
Key design criteria included:
  • Improve functionality and visual appearance compared to existing structure
  • Easy to clean, maintain, and repair, with the ability to replace side panels if necessary
  • Provide a comfortable, light and airy internal atmosphere without excessive heat or humidity, through all seasons of the year
  • Ability to open the sides in summer for weather control
  • Incorporate a hanging framework for flags, ropes and other equipment
  • Incorporate a mechanical ventilation system and a suspended internal ceiling liner within the roof space to aid internal environmental control
  • Capable of supporting heavy duty roof fans, artificial lighting, and electrical cabling
  • Structural steel framing to have corrosion protection suitable for an indoor chlorinated pool
  • Existing air-supported membrane to be removed and recycled in accordance with the ACT "No Waste" strategy
The Solution:
The standard Supa-Span-C design was customised to incorporate key project requirements. The steel truss framing was engineered to integrate the required electrical and fire detection systems, and manufactured with a special three-coat high build paint, to avoid erosion. Ferrari 702s membrane was chosen to clad the structure with the 502s range selected for an internal liner.
With the use of translucent membranes allowing natural transmission of sunlight, the requirement for daytime lighting has been significantly reduced. To support and regulate climate control, a mechanical ventilation system operates between the external membrane and interior liner creating an insulation air gap, and mesh vents along the sides of the structure provide the required air and moisture release. A retractable curtain walling system has also been implemented to allow cross ventilation during warmer weather.
In an Australian first, the existing air supported structure was dismantled and recycled using the Texyloop process. Developed by the Ferrari and Solvay™ Groups, Texyloop involves the closed loop method of recycling polyester-PVC composite textiles. Until the arrival of Texyloop, these composites were not fully recyclable due to the difficulty in separating the PVC from polyester fibres. Now these textiles can be separated, minimising the impact of raw material consumption and landfill or pollution through incineration.
Installation of the structure was very difficult due to the limited site access and construction over the existing in-ground swimming pool. Steel assembly was completed in the adjoining car park with the completed arches crane lifted onto the site. The fabric was also crane lifted from the car park to the top of the completed frame and then spread out over the steel frame, fixed, and then tensioned. The installation was completed in approximately four weeks. The existing entrance canopy was also refurbished with new fabric and better blind systems, and mechanical glass sliding doors were added to provide entry into the pool.
