News update - August 2007
A brief synopsis of some of the key news items related to technical guidance,
construction practice, and new regulations that you might have missed in the
press.
Contaminated concrete concerns
David Turner, president of the UK’s Institute of Demolition Engineers, said that
there is “a serious lack of knowledge of the CDM regulations” at the local
authority level and called on the UK’s Environment Agency (EA) and NFDC to
resolve issues concerning the disposal of concrete and hazardous wastes.

Energy Performance Certificates ‘go live’ as Home Information Packs
come in
Home Information Packs (HIPs) have become mandatory on sales of properties with
four or more bedrooms. The HIPs will be completed by the vendor and will provide
details of land searches, title
deeds and the property’s Energy Performance Certificate (EPC). The EPC will
assess the building’s energy efficiency and recommend how, if required, to beef
it up. It is hoped the move will help cut the impact that homes – which are
responsible for around a quarter of the UK’s carbon emissions – have on climate
change.

Scalding risk from domestic hot water systems
HSE has issued a safety alert to individual homeowners, tenants, landlords
and the plumbing industry. This is to raise awareness of a rare but potentially
serious scalding risk from domestic hot water systems which include a fixed
all-electric or part-electric immersion heater in conjunction with a plastic
cold water storage cistern or ‘tank’ located in the roof space.

The forecast that’s right up your street
The Met Office are developing detailed town-by-town forecasts that show
precisely where extreme rain will fall. By 2011, new computers will allow
forecasters to predict the exact path of downpours such as those that flooded
Tewkesbury and Gloucester.

Newcastle’s homage to Frank Lloyd Wright goes on sale
The North East’s
answer to Frank Lloyd Wright’s 1930s masterpiece Fallingwater, which claims to
be one of the UK’s finest examples of 1970s architecture, has been put up for
sale. Called Falling Waters, in a misspelled nod to Wright’s own work, the
family home is so named because of its proximity to Newcastle’s Jesmond Dene
park and its waterfall. The house was designed by local practice Ronald
Chipchase and Partners in 1973 and has been listed on the market for Ł2 million.

St Paul’s, meet Darth Vader cathedral
Lord Foster is to build a futuristic
twin for St Paul’s Cathedral, just 600 yards from Sir Christopher Wren’s baroque
masterpiece, at an estimated cost of Ł300m. The practice has won planning
permission for an office complex built into a giant dome just 10ft shorter than
St Paul’s.

Tender prices are continuing to soar
Building prices in Greater London have
risen by 8 per cent over the last year and will continue to rise at this rate
for another two years. Output in Greater London broke the Ł10 billion mark
rising 18 per cent in cash terms last year, a rate of growth matched only by the
North East. Rapid growth across the board – led by a 60 per cent growth in
private commercial - means contractors are cherry-picking their projects.
Holding the “bargaining power in contract negotiations”, they are increasing
risk allowances and negotiating “healthy” margins. Large and complex projects
attracted a premium of up to 4 per cent over and above underlying inflation over
the last year. Materials cost inflation, although still high, eased off to 2.9
per cent in 2007 after hitting a peak of 10 per cent in 2006. However increased
demand for timber in Europe, Middle East and China has led to a 15 per cent leap
in prices in 2007, and shows no sign of cooling. And an expected dip in steel
prices has not materialised, prices shooting up between 90 and 150 per cent over
the past 18 months. Davis Langdon reported a 35 per cent rise in private housing
output last year with social housing up by 75 per cent. Infrastructure rose by
just 1 per cent (Ł200 million) in cash terms but has declined in real terms by
30 per cent.

documents, geared to clients as well as to designers, covering performance
requirements and specifications and giving design examples.

Performance of recycled aggregates in concrete
A new report launched by
WRAP (Waste & Resources Action Programme) provides detailed technical
information on the performance of recycled aggregates in concrete. The research
demonstrates that blending 20% recycled aggregate with natural aggregate does
not have a negative impact on concrete performance. A total of 125 concrete
mixes were cast and tested using a number of different aggregates including
natural aggregate, crushed concrete, crushed brick, combinations of brick and
crushed concrete, and recycled aggregates sourced from recycling plants in the
“as produced” condition. Tests were carried out to determine: cube strength,
flexural strength, elastic modulus, drying shrinkage, initial surface
absorption, carbonation resistance, chloride ingress, freeze/thaw attack,
abrasion, sulphate attack and leaching. The research produced general guidance
supporting the wider use of recycled aggregates in concrete as well as grouping
aggregate particle composition into three classes of recycled aggregate suitable
for different applications.

Bridge to link Denmark and Germany
Denmark and Germany have signed a
Memorandum of Understanding that will see construction of a new € 4.2 billion
bridge linking the two countries across the Baltic Sea. Known as the Fehmarn
Belt Link the 20 km long bridge is expected to start construction in 2011, with
completion scheduled for 2018.

United Arab Emirates
In a break with their usual temporary installations,
the artist Christo and his wife Jeanne-Claude have unveiled a plan to build a
giant pyramid of oil barrels in the desert of the United Arab Emirates. The idea
for the 150-metre (500-foot) monument, roughly two thirds of the height of the
Eiffel Tower, with a flat summit, made up of 390,500 oil barrels piled up
horizontally, dates back to the 1960s. The so-called Mastaba project takes its
name and shape from the rectangular funerary constructions of Ancient Egypt. The
exact location for the pyramid, which will be entirely in yellow-orange shades,
has yet to be finalised. Models for the Mastaba project can be seen at the
Galerie Guy Pieters in this southern French town until September
