Another
Double Bill
That
was the format for Northern Branchs' latest evening
seminars on the 27th January 2005.The venue was the
extensive Alred McAlpines Utility Services
training centre at Nash Road ,Manchester who also provided
an excellent buffet prior to the start of the evening.
With
an attendance on a cold January evening in the mid thirties
the first presenter of the evening was introduced by
Northern Branch chairman Mark Jordan
and has become the norm an opportunity for a younger
member to take the first step on presenting.
Maria
Manidaki from Mott McDonald Bentley gave a
paper with the intriguing title of "Life
on Broadway". No, its not a glamorous
lifestyle in New York but more down to earth in Bradford.
Marias' presentation centred around the diversion and
protection of sewers up to 2440mm diameter in Bradford
City Centre to facilitate the Bradford Broadway redevelopment
and the commercial, technical and financial challenges
associated with the project.
The
Broadway development is a £300M redevelopment
of the city centre involving the demolition of the 1960's
city centre and redeveloping the shopping and office
blocks..Part of this overall plan is a section termed
"connecting the city" and is a £22M
plan to cover new roads, sewers, utility apparatus and
diversions to prepare the ground for development..
Maria
told us about the issues on the sewer network where
2 main trunk sewers crossed the site plus the Eastwood
and Bradford becks.
The arger 2440mm sewer was too large and costly to divert
so protection and improvements were made to this but
other sewers on site were diverted. Total costs of the
sewer works were £2.1M plus an additional £0.5M
of risk money.
With
such a large scheme on a relatively small yet commercially
valuable site what were the lessons learned.
Planning,Planning
and more Planning was key to actioning a smooth running
job.
Health
and Safety was crucial again foreseeing and planning
out issues.
The
Importance of Effective Communications again important
with many differing parties and customers invloved (e.g.
the local daily papers offices actually overlook the
works).
Research
before you dig to avoid unpleasant surprises and give
accurate forecasting and costs.
Certainly
the members of the audience were all impressed with
the quality of the presentation and Maria's in-depth
knowledge from a young presenter.
So,
moving to the main presentation of the evening came
Jim Watt, Operations Director of Environmental
Aggregates. Jim has worked as an engineering
manager with British Gas for 17years until 1995. He
then joined CableTel NTL as Head of Consumer Affairs
in Glasgow managing the build of the cable network before
joining Encore in January 2000.
His
presentation covered a no. of areas such as the history
of Encore and its raison d'etre. Every year in the UK
16 million tonnes of waste material arise from highways
repair and maintenance and was taken to landfill.
Encore
was a joint venture between British Gas and Kennedy
Contractors and was set up in 1998. The company aims
were to evaluate recycling the vast volumes of excavated
waste generated by their works. Since then Encore has
reprocessed more than 600,000 tonnes of waste which
would have otherwise gone to landfill.
Jim
then covered the processes and equipment used in the
quality process and protocol including inspection (prior
to accepting the material), segregation (prevents contamination),
pre-screening (maintains quality T1 R), blending (to
give best performance) and monitoring (of stocks, costs,
markets and material testing).
Jim
then looked back at resistance to use of recylced material
and against each point put the current position.
- Previous
Bad Experience - Material Quality much Improved.
- No
Cost Differential - Aggregates Levy.
- Doesn't
look The Same - Confidence and Use.
- Unsure-New
ground - Leading body/specifications for use.
- Is
it HAUC approved - provide RAUC Approval.
Moving
on, he then looked at some of the spin - off benefits
of using re-cycling such as:
- Mobile
equipment can be set up in a short space of time.
- It
provides a one stop shop for utilities reducing traffic
volumes.
- Ideal
locations are "orphan" sites ,old quarries,
contaminated land where surplus materials can be used
to re-generate environmental eyesores.
Encore
also won the VIBES (Vision In Business for the Environment
of Scotland) Award for demonstrating "Outstanding
Enviromental Good Practice.
Moving
towards a close Jom asked "Do we have a choice?".
The government does not want us to pay the Aggregate
Levy Tax; they want us to find new ways of working and
keep the resources we have already produced. Without
the levy there is little or no incentive to change. |
