Projects of the decade: Aecom

Aecom’s four diverse projects overcame big challenges and transformed a number of urban and rural spaces

Braid Burn

AECOM’s role

AECOM was commissioned to provide the design and economic analysis for the Scottish Government, carry out the detailed design and prepare the tender documents. AECOM is now supervising the works on site.

Other parties

■ Client City of Edinburgh Council
■ Contractor Carillion Construction
Environmental Regulator Scottish Environment Protection Agency(SEPA)
■ Archaeology City of Edinburgh Council
Nature Conservation Scottish National Heritage
■ Landscaping AECOM/Aedas

Start/finish

2002/2010

Cost

£20M

Brief description

This flood protection scheme will achieve 1 in 200-year protection for 750 residential and 110 commercial properties using nine temporary water storage areas and two large reservoirs.

Challenges

AECOM has to regularly consult with individual residents and community groups to minimise disruption in the urban area and be prepared to change the design throughout in order to mitigate utility diversion costs. The company is also providing an environmental specialist to minimise impact on bird, fish and mammal habitats.

Natural Vision at Chester Zoo

AECOM’s role

All design services including environmental studies, ecology, geo-environmental, building sustainability, transportation studies; services and structural design − lighting, fire, acoustics, thermal modelling, CEEQUAL, environmental assessment; appointing architect, landscape and specialist designers.

Other Parties

Client Chester Zoo
Architect Proctor & Matthews
Project Management and Cost consulting Turner & Townsend

Start/finish

Summer 2011/Winter 2014

Cost

£65M for phase 1

Brief Description

Tropical bio dome (95m by 190m) contoured to reflect Cheshire landscape, steel shell construction with ethyl tetra ethylene translucent panels.

Challenges

An extraordinary challenge to create a tropical rain forest where gorillas, chimpanzees and other animals can roam freely in and out of a 1.4 acre bio dome with humidity of up to 80% and temperatures of up to 30c. The highly sustainable site, set in 6.6 acres of ground, includes 250m2 rain recycling tank, biomass, animal and human waste treatment and green roofing.

Halley VI

AECOM’s role

Structural Engineer, Building Services Engineer, Fire Engineering, Acoustic Engineering, Sustainability Consultant and Design Project Management.

Other Parties

Client British Antarctic Survey
■ Architect Hugh Broughton Architects
■ Contractor Morrison (Falklands)
■ Hydraulic Specialist Bennett Associates

Start/finish

July 2004/March 2011

Cost

£24.5M

Brief Description

AECOM has designed and is building a pioneering new mobile, modular Research Station for the British Antarctic Survey, home to 52 scientists working in temperatures as low as -56C. With four previous stations eventually forced into the sea by glacial movement, the new building is relocatable, lifted above the snow on hydraulic legs with skis that allow it to be towed to new locations as the ice shelf recedes.

Challenge

The design beat 86 entries in an international competition to design and build Halley VI on the Brunt Ice Shelf, 16,000km away from the UK. With a construction season of two months, the modular design accommodates deliveries to site of 6.5t of material per sledge load. The building has to resist annual snow accumulation of 1.5m, temperatures that dip to -56C and 100mph wind speeds.

Manchester Metrolink

Manchester Metrolink

Manchester Metrolink

AECOM’s role

AECOM is the multidisciplinary consultant providing preliminary and detailed design of the new extensions to the Manchester Metrolink, including environmental services.

Other parties

Joint Designer Jacobs Engineering
Contractor MPact-Thales, a construction joint venture between Laing O’Rourke, Volker Rail and Thales

Start/finish

June 2008/August 2011

Cost

£575M

Brief Description

New Metrolink lines will cover nearly 32km and nearly double the size of the network, saving around 5M car journeys annually.

Challenges

The new tram lines will run to Oldham and Rochdale, Droylsden in East Manchester and Chorlton in South Manchester as well as providing a 0.4km spur to Media City UK in Salford Quays. The challenge has been to thread a new tramway through the streets of East Manchester. To speed construction the track slab is being slip-formed, a first for a tramway.
