Project:ChinaHuarongTower

Location:Hengqinzhen,Xiangzhou,Zhuhai,Guangdong,PRC

Type:Mixed-useDevelopment

Scheduled Time of Completion:TotalCompletionisscheduledforDecember2014

Rapid Design Development and Integrated Collaboration

Atkins has been announced to design the China Huarong Tower. After winning the one-month competition, the project was set on a “fast-track”, reducing design development time to only two months for delivering the final scheme design. In order to fully embrace the rapid design development, the BIM workflow, centred on Revit has been adopted. Revit also enabled integrated collaboration with structural and environmental engineers by sharing one 3D design model.

ABouT CHInACHEM

The Chinachem Group (“Chinachem” or the “Group”) is one of Hong

Kong’s best-known and most prolific property developers, with a

successful corporate history of more than 40 years. Still the largest

privately held group of its kind.

The early years of the company were dedicated to exploration of, and

investment in, agricultural projects and chemicals, but in the 1960s, the

Group was one of the first to see the future of property development in

Hong Kong and shifted its focus to the development of the city. It has

subsequently contributed tremendously to the city, working to meet the

needs of its citizens.

By the mid-1970s, Chinachem had grown from a burgeoning company

into one of Hong Kong’s largest property developers. The group has

consistently maintained its position as a forward-thinking pioneer in the

industry, active in the development of new towns and districts in Hong

Kong. Tsuen Wan, Kwai Chung and Shatin were all developed in large

part due to the dedication and foresight of the Group. Through their

consistent efforts to improve Hong Kong, the Group continues to create

private residences for elegant living for a wide range of Hong Kong’s

residents and families.

Today the Group boasts an impressive and diverse range of high-quality

properties that span Hong Kong Island, Kowloon and the New Territories,

with business interests including hotel ownership and operation,

residential and commercial properties, as well as retail and industrial

interests in a number of Hong Kong’s best-known and most iconic

buildings.

Chinachem has added to its portfolio of business interests on a global

scale, investing in ventures related to its core businesses and associated

industries, together with biochemistry, electronics, education and

finance.

With BIM, our team works efficiently with landscape architect during the design process. BIM visualizes the design and extracts 3D geometry data to assist the decision making concerning aesthetic, function and cost.

Through the collaboration, BIM successfully helps to maintain the design principle while optimizing the structural design to reduce significantly the concrete volume and in turn the construction cost.

BIM helps not only to visualize but also facilitate the design, saving time and cost ultimately.

Project:ConstructionofPublicRentalHousingatShaTinArea52Phase1(knownasShuiChuenOPh1)

Location:ShaTin,HongKong

Type:PublicHousing

Scheduled Time of Completion: February2014

Pioneering BIM for Quantity Surveying

The Housing Authority is implementing probably the Greater China Region’s first project for obtaining detailed quantities data from a BIM model. The “5D” model – with three physical dimensions plus time and cost data – generates data far more quickly than traditional QS methods. The standardised approach and guidelines developed in the project may extend the use of BIM in the construction industry.

The Hong Kong Housing Authority (HA) develops and implements a

public housing programme which seeks to achieve the Government’s

policy objective of meeting the housing needs of people who cannot

afford private rental housing. Approximately 30% of the Hong Kong

population is now living in public rental housing units.

The HA plans, builds, manages and maintains different types of public

housing, including rental housing estates, interim housing estates, and

transit centres. In addition, the HA owns and operates some flatted

factories and ancillary commercial and other non-domestic facilities. The

HA also supports the Government’s policy in providing subsidised home

ownership flats to qualified persons.

The Housing Department (HD) acts as the executive arm of the HA to

Scheduled Time of Completion: 2015

Mega Station Builders Deploy Mighty BIM

The MTR Corporation is making extensive use of BIM during the construction of the West Kowloon Terminus, by far the largest railway station in Hong Kong. The massive, detailed BIM model was originally deployed for modelling the Terminus structure ahead of construction to identify spatial clashes and construction co-ordination issues, its uses have expanded through collaboration with the project teams within MTR Corporation and its contractors. The project team plans to leave a legacy in the form of an ‘as built’ model in addition to the usual as built drawings to the terminus operator.

ABouT MTr CorPorATIon LIMITED

Carrying an average of 4 million passengers every weekday, the MTR is regarded as one of the world’s leading railways for safety, reliability, customer service and cost efficiency.

The MTR Corporation was established in 1975 as the Mass Transit Railway Corporation with a mission to construct and operate, under prudent commercial principles, an urban metro system to help meet Hong Kong’s public transport requirements. The sole shareholder was the Hong Kong Government.

The Company was re-established as the MTR Corporation Limited in June 2000 after the Hong Kong Special Administrative Region Government sold 23% of its issued share capital to private investors in an Initial Public Offering. MTR Corporation shares were listed on the Stock Exchange of Hong Kong on 5 October 2000.

The Corporation marked another major milestone on 2 December 2007 when the operations of the other Government-owned rail operator, the Kowloon-Canton Railway Corporation, were merged into the MTR, heralding a new era in Hong Kong railway development.

Other than bringing more efficient and competitively-priced services to local rail passengers, the merger brings new growth opportunities to the MTR Corporation’s businesses in and outside of Hong Kong.

The merged rail network comprises nine railway lines serving Hong Kong Island, Kowloon and the New Territories. In addition, a Light Rail network serves the local communities of Tuen Mun and Yuen Long in the New Territories while a fleet of buses provide convenient feeder services.

The Corporation also operates the Airport Express, a dedicated high-speed link providing the fastest connections to Hong Kong International Airport and the city’s newest exhibition and conference centre, AsiaWorld-Expo.

From Hong Kong, passengers can travel with ease to Guangdong Province, Beijing and Shanghai in the Mainland of China using the MTR’s intercity railway services.
