British Construction Industry International Award 2002 is open to projects of any size outside the UK in which either the principal designer or the principal contractor is a UKbased British firm.
Seven entries were shortlisted to four schemes by the judging panel.
Presentations on these schemes were made by the project teams to the BCI Awards International judges in London. The judges then travelled to site for further interviews and first hand inspections.
The judging panel for the BCI International Award 2002 was: Bryan Jefferson CB, CBE, architectural adviser, Department for Culture, Media & Sport; Bob McGowan, former chairman, Scott Wilson Group;
and Alan Crane, chairman, Movement for Innovation.
Results of the International and all other BCI Awards will be revealed next Wednesday evening at the BCI Awards dinner to be held at the London Hilton, Park Lane. Details of the award winners and commended projects will be published in The Daily Telegraph and a supplement accompanying next week's NCE. Mike Winney reports
Accra Waste Project, Ghana
A huge improvement in the environment of a substantial proportion of Accra is attributed to this project which introduced modern sewage treatment to the city for the first time. It is also the first time in sub Saharan Africa that the upflow anaerobic sludge blanket treatment process has been used - claimed to be a robust and appropriate treatment method which involves minimal operation and maintenance costs.
Taylor Woodrow has a long term commitment in West Africa going back 50 years. The need for a waste project for Accra was identified in 1992 and the company put together a scheme and the finance to build it.
Night soil had previously been simply dumped in skips at uncontrolled tips and left to evaporate - or more likely overflow. This project created a network of 60 underground storage tanks from which tankers carry accumulated sewage to the central treatment plant. A properly engineered solid waste disposal site has also been created.

Robert Benaim & Associates have something of a reputation for coming up with alternative designs for viaducts, especially structures carrying railways. In Hong Kong some 22km of viaduct deck were needed for the West Rail project.
An alternative monolithic design was developed and used for construction which eliminated bearings, reduced airborne noise and made substantial materials savings. Cost savings at tender were £35M on an estimated £210M conforming bid.
The viaducts were constructed as a series of portal frames with the post-tensioned precast segmental deck boxes connected to the pier heads with monolithic joints. Key modification to the conforming design to reduce airborne noise generation was to position the box web sections directly under the rail centres, reducing high frequence bending deflections in the top slab.

Arup Energy's ACE offshore platform used in the West Natuna field is believed to be the world's first truly relocatable gas production platform.
It consists of a barge deck, lattice legs raised and lowered by strand jacks and a pumping system - all mounted on a steel gravity base adaptable for a variety of sea bottom conditions.
The jacking arrangement sets the structure apart from conventional jack up platforms.
Employing a strand jack system rather conventional jack up barge technology eliminates high local loadings on the legs. This means that neither forged and cast steel components nor special grades of steel are required.
Major cost savings result because the deck can be manufactured using plate-line fabrication as widely employed for ship construction.
The jacks are dismantled and removed once the platform is in position, giving a far clearer work space on the deck than with a permanent jacking installation.
When production is complete at the well site the jacks can be reassembled and raise the base so that the platform can be moved to another production site or a dismantling yard.

Five multi-lane highway tunnels were required to carry the Boston Central Artery beneath a complex network of seven interconnecting railroad lines at the approach to the city's South Station.
Mott Macdonald and a specialist team of British contractors convinced the Massachusetts Turnpike Authority and its consultants that three jacked tunnels driven through specially frozen ground would be a better option than the original plan to relocate the tracks and dig a series of open cuts from the surface.
Precast concrete jacked tunnels on this scale had not been attempted anywhere before.
They had to slip tightly beneath the main railway lines on which there were extremely small tolerances on permitted heave or settlement, and without interrupting the train service. It was the only project on Boston Central Artery that was completed to time and budget.
