These Technical Conditions of Tender shall be read in conjunction with the Control Plans provided in the Developer’s Packet. 2 Technical Conditions of Tender 2.0 INTRODUCTION TO THE SITE AND ITS URBAN CONTEXT 2.1 Marina Bay, Singapore’s Downtown 2.1.1 The Marina Bay area, Singapore’s Downtown district, is located at the heart of Singapore’s city centre. It comprises the existing Central Business District (CBD) at Raffles Place, Shenton Way and Marina Centre, together with the new development areas around the Bay at Central and Bayfront Subzones, as shown on the Control Plans. The district is envisioned to be an international business and financial hub and part of a 24/7, waterfront ‘Garden City by the Bay’. Marina Bay reflects Singapore’s position as a dynamic global city. It is a great place to live, work and play; a place to explore, exchange and entertain. 2.2 City Around the Bay 2.2.1 The new development area around the Bay is being developed from two directions. One direction is from the existing CBD and comprises the developments at One Raffles Quay, The Sail @ Marina Bay, the Marina Bay Financial Centre, Asia Square Towers and Marina One. The other direction is from Marina Centre and comprises the development at Marina Bay Sands, which has extended the critical mass of exhibition and convention, hotel and entertainment facilities into the Bayfront area. 2.2.2 Marina Bay is a vibrant destination with a good mix of commercial, residential and entertainment uses. The area has been established as a major business and financial precinct to complement the existing CBD and is home to many major local and international companies and financial institutions. 2.3 Vibrant Activities 2.3.1 The 48 hectare (ha) water body at Marina Bay forms part of Marina Reservoir, which also includes Singapore River, Marina Channel and Kallang Basin. The Bay is a key urban water space within the city, a meeting place for the nation and a focal point for celebrations and activities. The extensive waterfront promenade around the Bay forms a natural amphitheatre to accommodate large crowds of spectators, making it an ideal stage for events. Marina Bay is a source of national pride, where Singaporeans and visitors of all ages can come together to enjoy the unique location and attractions. 2.3.2 Marina Bay has already been the venue for many major events. These include national celebrations, international water sports competitions, outdoor concerts and firework displays. It is also a place where the local community learn to sail, canoe and kayak. Water taxi services within the Bay serve the developments in the area and along Singapore River, with boat landing points at Marina Bay Sands, Marina Barrage, etc. 3 Technical Conditions of Tender 2.4 Necklace of Attractions 2.4.1 The development plans for Marina Bay feature a continuous ‘necklace’ of attractions along the waterfront. These include the Merlion Park, the Esplanade – Theatres on the Bay, the Singapore Flyer and Gardens by the Bay. 2.4.2 The two promontory sites have been set aside for the development of major public attractions and distinctive landmark buildings. The Bayfront Promontory site has been developed as the ArtScience Museum as part of the Marina Bay Sands development. The Central Promontory site is currently retained as an interim open space, known as the Promontory @ Marina Bay, and is a popular location for events and activities. Along the historical waterfront at Collyer Quay, the existing pier structures and buildings at the former Clifford Pier and the former Customs Harbour Branch have also been retained and developed as part of the Fullerton Heritage waterfront and lifestyle development. 2.5 Pedestrian Promenade 2.5.1 The continuous pedestrian promenade and two pedestrian bridges link together the developments, attractions and public open spaces along the waterfront and form a 3.35 kilometre (km) route around the Bay. In addition to The Helix, the Jubilee Bridge, completed in 2015, enhances connectivity and the pedestrian experience along the waterfront by linking the Esplanade Theatres and Merlion Park. 2.5.2 The promenade is a popular destination. It includes a variety of spaces that cater to individuals, small groups and large crowds, as well as accommodates a range of activities and events. There is lush tree and shrub planting to create shady and comfortable places, and steps and ramps that allow people to go closer to the edge of the water. In addition to the large scale events, community events such as big walks, flea markets, and marathons, are held regularly at the waterfront. Many of these are initiated by the community and include small groups of runners and yoga enthusiasts who meet to use the waterfront as a location to exercise and relax. Such events and activities add year-round vibrancy to Marina Bay, reinforcing it as an endearing and community space for all. 2.6 Garden City by the Bay 2.6.1 The Gardens by the Bay, comprising three waterfront gardens with a total area of more than 100ha, are being implemented in stages within the Greater Marina Bay area. Bay South Garden is the largest of the three gardens. It includes a Conservatory Complex with the Flower Dome and Cloud Forest cooled conservatories, and a Supertrees Grove which incorporates vertical greenery with environmentally sustainable functions, for example, to collect rainwater. More parkland will be opened up when subsequent phases of the Gardens (Bay East and Bay Central) are completed. In addition, the waterfront promenade around Marina Bay will be 4 Technical Conditions of Tender extended to the entire Marina Reservoir, totalling 11.7km in length, and integrated with the future Round Island Route (RIR). 2.6.2 Marina Bay is planned to include a series of distinctive districts, clustered around major public open spaces and signature streets. These open spaces and streets will provide prestigious address locations for the surrounding developments and create an amenity for people living and working in the area. The public open spaces will be complemented by a series of pocket parks, sky terraces and roof gardens within the individual developments to create a lush tropical landscape and unique sense of place, reinforcing Singapore’s ‘City-in-a-Garden’ image. The roads and public open spaces will have unique tree and shrub planting utilising different forms, colours and fragrances to provide a delightful visual and sensory experience. The specific planting schemes will reinforce the street hierarchy and provide a sense of orientation and direction within the area. 2.7 State-of-the-Art Infrastructure 2.7.1 All developments within the area, including the development on the Land Parcel, will be served by the Common Services Tunnel (CST), a comprehensive system of underground tunnels which houses and distributes utility service lines, including electricity, potable water, chilled water, NEWater and telecommunication cables. This allows for power feeds, fibre optic cabling, and capacity for expansion to meet changing utility needs. 2.7.2 A District Cooling System (DC System) is in operation to serve the developments within Marina Bay. The first district cooling plant is located at One Raffles Quay and the second district cooling plant is located at Marina Bay Sands. Singapore District Cooling Pte Ltd (SDC), hereinafter referred to as DCS Licensee, is the operator of the DC System at these two district cooling plants. All developments are encouraged to take chilled water supply from the DC System. 2.7.3 The DC System supplies chilled water 24 hours daily through a piping network for air-conditioning of buildings. The DC System dispenses with the need for individual buildings to have stand-alone chiller plants and there is GFA savings if the developments choose to take chilled water supply from the DC system. These space savings can then be converted to more usable space. 2.8 Convenient Road, Rail, Cycling and Pedestrian Access 2.8.1 Marina Bay is planned to be well-connected to other parts of the city and to the rest of Singapore via a comprehensive and efficient transport network. The area is well-served by major expressways including the Marina Coastal Expressway / Ayer Rajah Expressway (MCE / AYE) and the Central Expressway (CTE), arterial and access roads. Multiple rail lines serve the area, including the North-South Line (NSL), East-West Line (EWL), Downtown Line (DTL), Circle Line (CCL), and the future Thomson-East Coast Line (TEL). The area has also been planned with an extensive 5 Technical Conditions of Tender network of at-grade covered walkways and tree-lined walkways, and both underground and second storey pedestrian links, creating a pedestrianfriendly district. 2.9 Vision for the Future Development A Unique Gateway for the City 2.9.1 The Land Parcel is strategically located with a prominent frontage along Central Boulevard and Raffles Quay-Shenton Way, two key roads within Marina Bay and the CBD. The future development on the Land Parcel will offer excellent views for tenants to the Marina Bay waterfront to the northeast, green open space to the south-east, and the across the CBD to the west. The Land Parcel offers a unique opportunity to develop a distinctive landmark mixed-use development that is well-designed and features highquality architecture and landscaping that will underscore the importance of the site within the city. A Well-Connected Part of the City 2.9.2 The future development will be conveniently connected to the rail network through a direct underground pedestrian link to the Downtown Mass Rapid Transit (MRT) Station, providing convenient and seamless access to the island-wide rail network. It will also be linked to other stations, such as Raffles Place Interchange MRT Station, Marina Bay Interchange MRT Station, and the upcoming Shenton Way MRT Station (slated for completion by 2021), via the underground and elevated pedestrian network. 6 Technical Conditions of Tender 3.0 SUMMARY OF PLANNING AND URBAN DESIGN REQUIREMENTS 3.1 The successful tenderer is required to comply with the following planning and urban design requirements for the development on the Land Parcel.
