INTRODUCTION
LOCATION The Graduation Urban Studio initially proposed a master plan for the full extent of The Bays Precinct - each of Blackwattle, White and Rozelle Bays were explored – which lead to a selection of a specific site, Glebe Island was examined closer with an inherently public program, developing a complex architectural and urban project derived from a master plan proposal. The Project derived was ‘Places of Performance’ a place for the amateur to professional performer. A flexible and adaptive place for gathering, observing and performing. It is a place for community, school eisteddfod, cultural organisations and dance companies. Looking back through the history of Glebe Island, it soon becomes obvious that the island hasn’t changed its identity through various modes of commercial industries, Glebe Island hasn’t had a living community since European settlement, the memory and place has been about working along side the water.
‘Places of Performance’ is a project to give the bays a new identity within the ‘Living Local’ masterplan. The ‘Living Local’ masterplan gives context to the selected site. When visiting Glebe Island and the surrounding areas, the key identifiable and lasting memories of the area are the three heritage artefacts on the site. The defining feature and initial concept of the master plan is the heritage axis, linking The Power Station, Silo and the Swing Bridge. This idea of place and memory are embodied by these three heritage artefacts in which the people of Sydney associated with the Bays Precinct. It is in the new cultural buildings in the masterplan that the new memories and ideas of place are created. ‘Places of Performance’ focuses in on one of these three cultural buildings the theatre. The theatres and its surrounding civic areas form a performance district to create an urban character explored through different scales of social interaction, experiences and the transition between the amateur to professional.
USE/FUNCTION OF THE SITE
INTRODUCTION
‘Places of Performance’ focuses on two main areas: The theatres and the civic space. Within the performance district there are two theatres; The Dance Theatre comprises of a 500 seat two story auditorium, full back of house facilities, rehearsal studios, wardrobe and change, green room, offices and a restaurant. The Recital Theatre comprises of a 600 seat auditorium, a multi purpose function area, a 250 seat lecture theatre, wardrobe and change and green room. The two theatres are both connected underground through a dock level sharing back of house areas. Supporting the two main theatres buildings, The Performer’s Entrance provides an alternative back of house entry for staff and performers, the building provides amenities and a cafe. The Civic space between theatres and within the performance district, are areas for amateur performer to use as a stage for their performance.

INTRODUCTION
DESIGN APPROACHES & KEY DESIGN IDEAS Built Environment The Performance District is directly related to the metro system to provide accessibility and walk ability. The dance theatre therefore is aligned to the Sydney Harbour Bridge and the metro station to form the main axis of the district. A key design idea is to have the performance district a pedestrian based area, this provided challenges with access for the back of house, the decision was made to connect the dock to both theatres providing a back of house sequence; from performers entry to the stage. Throughout the performance district the concept of observation and viewing can be seen everywhere. Each theatre has a large foyer volume that also provides a sequence of entry; from ticketing to pre show lobby. The overall concept within the theatres is this idea of viewing in and viewing out, an idea about dark and light space in which to perform and observe. The Facade is a direct response to this framing and directing the viewer to certain aspects of the city and the performance district.

INTRODUCTION
DESIGN APPROACHES & KEY DESIGN IDEAS Civic Environment The civic space around and between the theatres provides space for amateur performers to use as a space to perform. The main idea was to provide different scales of amateur and public performance; from soloist to the outdoor amphitheater. The Urban Spines are directly formed by the design language from the facade details of the theatres, however they provide opportunities for planting, seating and a space, defining a small platform or stage for a performer to use. The urban spines run along the main axis of the district. The Urban Spines provide a performance of 1-2 people, mainly aim at people passing by, ‘The busker’. The Amphitheater stages provide an organised outdoor event with a higher level of production, ‘The Festival’. What this project looks to solve is the missing scale in the civic performance, the middle ground between a busker and an orgainsed event. ‘The Street Performance’ is a performance 1-5 people that stops and forms a crowd which engages with the performer, they stop and pause. Providing different scales of interaction is the overarching goal for the civic space.

INTRODUCTION
CLIMATIC CONDITIONS Due to the large concrete surface at the base of the theatres, investigation of the potential solar collection within the civic area took place. Three simulations were run to understand the amount of cumulative insolation that could be obtained to power the proposed solution. A Summary of the results below: At the Winter solstice numbers below 1 kWh/sqm were estimated. At the Summer solstice numbers below 3 kWh/sqm were estimated. A year long cycle numbers below 5 kWh/sqm were estimated. Due to the overshadowing of the theatres, the numbers were below anticipated, another option will be looked at to use for energy collection.

DESIGN SOLUTIONS & CONSTRUCTION APPROACHES The design solution proposed was formulated to achieve 2 main goals; a structure overhead and energy collection. The design solution looks to provide a medium sized street performance area for performers to use. The Structure can be broken down into two different parts; The Canopy - which comprises of an acoustic and fiber optic material attached to a deployable structure controlled by the spar. The spar is the central unit that controls the length of contraction and expansion, the spar can tilt the canopy to provide a more suitable cover for protection and acoustic performance. The Reels - provide movement to the canopy within a programmable limit box, this gives the boundary of the movable area for operation. Larger reels of high tensile cable sit at the base of the vertical posts which provide the main support for the whole system. Pulleys at the top allow the cable to connect to the spar.

Energy Collection is achieved through kinetic pavement, sections under the canopies are paved to proved energy to the system. The system also runs on the data mapping that pavement provides. The data provided by the pavement reveals hotspots or large gathering of people, this data is processed and then gives coordinates to an area under the canopies structure. A sensor under the canopy gives data on acoustics and analysed with the data from the kinetic pavement to give information to the spar to deploy the canopy’s structure, this allows the canopy to expand to meet the needs of the performance. The underlining construction approach is similar to that of a cable-suspended camera system used within stadiums, with the deployable structural system similar to an inverted umbrella or portable gazebo.
CONSTRUCTION
TECHNOLOGY The Canopy’s ability to move and operate has been derived from the technology used with cable-suspended camera systems, using this as a starting point the canopy like the camera can be suspended over a large volume of space only using four points of contact. The Canopy from here can be contained in a 3d virtual box, allowing the canopy to move in all directions within the box. What makes the canopy step away from the camera system is the weight, where the camera system is built for steadiness and speed, the canopy needs only to be held up and move at a fraction of the speed. At its bare bones the base of the system can be achievable through current technology and construction techniques with the cable and reels up specced to accommodate the weight. The Canopy’s deployable structure is achievable with current structural components. In its base form, the structure is a scissor arm connected with pin joints. The structure can be deployed through one point in the center and when combining the scissor arms to form a complex 3d system each arm supports each other. Improvement could be explored by stabilisation and seeing the effect of wind on the system as a whole.
Kinetic Pavement is a new technology being explored through using footsteps as usable energy. The technology uses vertical displacement on pressure pads traveling between 5-10mm into a electromagnetic induction generator. Pavegen a company leading in the technology states that one step with a vertical displacement of 5mm is 8 watts of kinetic energy over the course of the footstep, resulting in a LED streetlamp turning on for 30secs.1 Pavegen also state they can use the data from the peoples movements to locate hotspots or paths, with this data I purpose the canopy uses this information to locate groups of people and a way to position itself to deploy. The acoustic fabric that is proposed in the solution is an unknown, the fabric would be a combination of two materials which can be derived from a flexible acoustic material currently used in todays applications and fiber optic material or flexible LED fabric. Currently fiber optic material is embedded into a textile surface, the new material would use this technique of embedding into an acoustic fabric to produce a material that can be used for visual and acoustic effects. 1 https://newportpartners.wordpress.com/2018/09/14/what-is-kinetic-paving/

KEY ASPECTS
CONCLUSION
The project set out to provide the inbetween scale of civic performance missing from the project ‘Places of Performance’. The project addressed the large unresolved blank concrete area infront of the dance theatre. Using innovative technology such as kinetic pavement to capture foot traffic as a source of energy for the installation, the data collected provided real time information of the location and paths of the people passing by. This data is used to give the canopy, a deployable shade and acoustic amplifier a destination. The canopy lined with an acoustic and fiber optic embedded fabric, the canopy’s ability to move is operated in a cable-suspended system which allows free movement within a 3d virtual box. The canopy creates and defines space for a street performance within the performance district.
