PLAN LONDON 2012 OLYMPIC PARK, UNITED KINGDOM Atkins was part of the team delivering the design of the Olympic Park infrastructure for the Games and the Legacy 4 Transportation projects. Working in collaboration, we helped transform the 246ha site in time for London 2012. A 450-strong Atkins team worked side-by-side on the project to allow 11,000 workers safe access to the park’s differing construction sites. In a short period of time our bridges have seamlessly transformed from construction utility structures into dramatic park spaces during the games and then into durable legacy bridges for the local community. 4 Collaboration Innovation Sustainability Having the right people to work Most bridge projects are novel; As engineers we have a responsibility on an infrastructure programme or that’s what keeps our passion to society to provide practical and project is essential in making the right for engineering solutions fresh. holistic solutions, so sustainability choice.

The main approximately 40m across the Staunton Creek Nullah. structure was delivered to site by barge before installation The superstructure of the bridge is prefabricated and of the glass canopy and parapets with glass balustrade. 6 ASIA PACIFIC ABERDEEN CHANNEL BRIDGE, DESIGN HONG KONG ISLAND, PEOPLE’S REPUBLIC OF CHINA Detailed design of 115m post-tensioned balanced cantilever bridge over the Aberdeen Channel and 7km of precast segmental viaduct, for the MTR South Island Line extension in Hong Kong. Tight site constraints to avoid existing structures, tie-in with an existing viaduct and matching the existing bridge were key challenges. Integral construction using split piers improved construction and long-term durability. 7 ASIA PACIFIC ENABLE SAI VAN BRIDGE, MACAU, PEOPLE’S REPUBLIC OF CHINA The 2.2km long viaduct over Praia Grande Bay connects Macau and Taipa Island. To accommodate the expansion of the Light Rail system the interior of the box structure required assessment and upgrading for new trains and enhanced safety measures. Atkins undertook assessment and design for this post-tensioned concrete box viaduct with a 400m long cable stayed navigation span. 8 PENANG BRIDGE, ENABLE MALAYSIA Atkins was the Client’s Special Advisor for the cable stay replacement scheme on the 13.5km crossing, carrying out structural analysis of the bridge due to traffic increases, conducting construction audits and advising on maintenance regime. 9 10 MIDDLE EAST RIYADH METRO, KINGDOM OF SAUDI ARABIA DESIGN Atkins is working on Package 3 (Lines 4, 5 & 6) Atkins value engineered the entire of Riyadh Metro supporting the Design & Build viaduct design resulting in significant savings to the Consortium FAST comprising FCC, Samsung C+T, consortium. Struckton, Freyssinet Saudi Arabia and Alstom Transport. The viaduct’s section is covered with either single cell box girders or twin-precast U-girders. A full span Atkins was lead Consultant of a Design Joint Venture launching method is used for straight sections while comprising Atkins, Typsa, Setec and Sand Consult a precast segmental method is used for the curved for the full multidisciplinary design over the 75km stretch of the alignment. Longer viaduct spans over stretch of the alignment of which 30km is on elevated 50m and up to 92m are erected by balanced cantilever viaducts, 27km is underground and 8km is in tunnels or by cranes. along with 15 underground stations, nine elevated stations, two depots and park and ride facilities. 11 MIDDLE EAST DESIGN DURRAT AL BAHRAIN BRIDGES, KINGDOM OF BAHRAIN Design of 3.5 km of bridges to connect the man- made islands of Durrat Al Bahrain. Each 15m long simply supported voided deck slab was precast in two longitudinal sections, and connected by an insitu stitch. Foundations were designed to provide frame action for strength and structural stability of the bridge against lateral loads, including ship collision. 12 PRINCE TURKI BIN ABDULAZIZ DESIGN ROAD BRIDGE, KINGDOM OF SAUDI ARABIA Designed for the ArRiyadh Development Authority the Prince Turki Road bridge is a striking solution to one of the most congested intersections in the city. We have worked with Knight Architects to develop a number of concepts for the project and the selected option is a 210m long and 30m wide bridge, arranged in three spans of 60- 90-60m. The bridge deck is a steel through structure with two 3-dimensional side trusses as the main load-carrying elements. The side trusses also support the architectural cladding which fans out at mid span to provide shading to pedestrians coming out of the Metro station. Sculptural piers support the deck which seems to float on the substructures. DUBAI METRO VIADUCTS, DESIGN UNITED ARAB EMIRATES Design and technical construction support for 61km of precast segmental viaduct, including large diameter monopile foundations. Time dependent studies, rail-structure interaction as well as seismic design were key considerations. Atkins introduced new precasting and launching technology to the UAE permitting construction with minimal traffic disruption. 13 NORTH AMERICA DESIGN HAVEN AVENUE GRADE SEPARATION, UNITED STATES OF AMERICA The Haven Avenue Grade Separation is a commuter train and Burlington Northern landmark bridge in Rancho Cucamonga that Santa Fe freight trains. was built to ease traffic congestion caused by increased rail service in the area. Vehicle Atkins provided the structural planning, and train traffic were separated by lowering design, and construction support services Haven Avenue 9m, and building an for the award-winning grade separation underpass bridge to support the Metrolink structure. DESIGN FIRST STREET WIDENING, UNITED STATES OF AMERICA The Metro Gold Line extension required approach span girders were configured to the 400m long First Street Viaduct in Los match the existing girders and the cast-in- Angeles, California to be widened in order place arch sections were exactly matched to accommodate two new light rail tracks.
