Dubai Light Rail - Red / Green Line Viaducts
Atkins is the lead designer responsible for all civil works associated with the Red and Green Lines of the Dubai Metro. Atkins role is the full multi disciplinary design and management of the civil works including viaducts and bridges (utilising post-tensioned, segmental construction), geotechnical and site investigations, bored tunnels, cut and cover tunnels, route alignment, elevated, at-grade and underground stations, depots and additional specialist services such as fire and ventilation, environmental impact, concrete durability and landscaping.

The elevated structures include 59.9km of segmental elevated viaduct and associated structures. Detailed design was carried out for all aspects of the viaduct design and erection including:

Improvements to San Tin Interchange
The design was undertaken by Atkins as part of the Contractor's designed section of works, effectively under a design and build arrangement. The improvements to San Tin Interchange will relieve congestion on Fanling Highway and allow for increased traffic flows at the Lok Ma Chau border crossing. The design scope included the deck designs, abutments, approach ramps, retaining walls and foundation designs. The viaducts are composed of 413m single box and 169m of twin box, precast segmental viaduct, erected using the balanced cantilever method of construction. In addition, 349m of insitu post-tensioned viaducts were constructed by the span by span method. The total length of viaduct is 931m. Temporary traffic management services were also provided on this very busy area near the border crossing.

Shatin New Town, Stage II - Road T3 and Associated Roadworks

Atkins China Ltd was appointed in November 2003, by Maeda Barbican Hsin Chong JV to carry out the detailed design for the Temporary Road No. 4, which was part of contract ST79/02 – Shatin New Town, Stage II, Road T3 and Associated Roadworks. The proposed Temporary Road No.4 provided a temporary access for vehicles to the Shing Mun Tunnel Bridge. The access consisted of 200m single carriageway viaduct and approach ramps. Atkins proposed a steel design that provided a more cost effective, simple to erect and shorter programme construction as compared to the conventional concrete construction.

HyD Contract 2002/26 Stonecutters Bridge - ICE
Atkins was commissioned by Maeda-Hitachi-Yokogowa-Hsin Chong Joint Venture to carry out an independent checking of the temporary jetties, which are gravity type with vertical blockwork seawalls, for berthing and mooring for self-propelled dynamically positioned barges and working barges for bridge construction, and temporary pad footing for steel deck segments lift up from barge and sliding to assembling location on the ground level under HyD Contract HY/2002/26, Stonecutters Bridge.

Contract No. KL/2005/01 Development at Choi Wan Road and Jordan Valley Remaining Infrastructure Work- Stage 1 - ICE
Atkins China Ltd was the independent checking engineer for Maeda Corporation for this project. The objective of the project is to connect a development near Jordan Valley with Choi Wan Road by the construction of two high level vehicular bridges and a footbridge, over a major highway with numerous ground level constraints.

Atkins was responsible for the independent checking of the contractor's cost saving alternative design for one vehicular viaduct, with associated abutments, piles, approach ramps and the footbridge foundation alternative check. Atkins also was responsible for the associated temporary works for the decks.

Contract P330 International Exhibition Centre at Hong Kong International Airport - ICE Checks for Permanent Works at AEL Station
Atkins was appointed by Dragages et Travaux Publics (HK) Ltd to carry out an independent check on the permanent works design of the Airport Expo' Station (AEL) at Hong Kong International Airport (now renamed as AsiaWorld-Expo Station) and the associated Link Bridge structure under the Contract P330.

HyD Contract HY/2003/19 Improvements to Tung Chung Road between Lung Tseng Tau and Cheung Sha - ICE
Atkins China Ltd was the independent checking engineer for China Civil Engineering Company Ltd. for this project. The objective of the project is to improve existing Tung Chung Road between Lung Tseng Tau and Cheung Sha.

Atkins are responsible for the independent checking of the contractor's alternative design for the vehicular viaduct, with associated abutments, piles, approach ramps. Atkins also was responsible for the associated temporary works for the decks.

KCRC East Rail Extension LDB201 Sheung Shui to Chau Tau Tunnels - ICE
Atkins are the Independent Checking Engineer (ICE) for the Dragages (HK) Joint Venture for the HK$2.8Billion Design and Construction of KCRC Contract LDB201 Sheung Shui to Chau Tau Tunnels.

HyD Contract No - HY/2002/23 Deep Bay Link - Southern Section - ICE
Atkins China Ltd was commissioned by the China State Joint Venture to carry out independent checking of all aspects of the temporary works including those associated with the construction of bridges, earth retaining structures, temporary slopes, temporary access roads, temporary excavations, temporary diversion of utilities and installation of lifting equipment such as tower cranes and gantries.

Atkins was also responsible for assisting the Contractor to analyse the impact of the erection methodology on the incomplete permanent structure. The unusual ”doubleblade“ column arrangement required protection measures under temporary loads. In the case where remedial measures were required, Atkins proposed solutions to minimise the extent of temporary works.

CEDD Contract ST79/02 Sha Tin New Town, Stage II, Road T3 and Associated Roadworks - Bridge N263
In order to relieve the predicted traffic congestion after diversion of all North bound traffic from Tai Po Road (Tai Wai section) onto the Shing Mun Tunnel Bridge under the CEDD contract ST 79/02 Shatin New Town, Stage II - Road T3, Atkins was commissioned by MBH Joint Venture to carry out structural assessment and the condition survey of Bridge N263 at Sha Tin Rural Committee Road. The viaduct supports the critical junction at which the additional lane of traffic was added.
