BASF Interested in Acquiring Degussa's Construction Chemicals Division
BASF is interested in acquiring Degussa’s construction chemicals division to expand its own portfolio
in a high growth market through forward integration. BASF’s Board of executive directors has
proposed to Degussa’s Board of management to conduct exclusive negotiations on the possible
transaction. Following a detailed review of the business case, BASF plans to make a concrete offer for
Degussa’s business. BASF wishes to start the review as quickly as possible.
The global construction chemicals market is valued at around €13 billion and is attractive in view of
annual growth of about 4%, relatively stable margins and high potential for innovation. The acquisition
of Degussa’s business would give BASF rapid access to additional industrial customers and endusers.
German mining company RAG, owner of a 50.1% stake in Degussa, announced on 19th December it
would acquire the 43% share in the specialty chemical giant now held by E.ON, effective 1st July,
2006. Analysts say the deal will effectively bring to an end Degussa's 132 years as an independent
company. But that independence has been precarious since 2002, when RAG first acquired a stake in
Degussa through a shares swap with E.ON.
It was partly to fund the E.ON buyout that RAG, in early December, pressured Degussa to seek a
buyer for its profitable construction chemicals unit. Within two weeks, fellow German firm BASF had
requested exclusive negotiations to acquire the business, which accounts for about 14% of Degussa's
annual sales.
According to Degussa’s annual report, the company’s construction chemicals division posted sales of
approximately €1.8 billion and an EBIT of €201 million in
fiscal 2004 with a global workforce of about 7,400 employees.
The division markets over 40,000 products in the Americas,

France. French Rail Network (RFF) decided on 6th December
to continue preparations for construction of the ProvenceAlpes-Cote d'Azur high speed line (read E-News Weekly
12/2005) following a four-and-a-half month public
consultation in which most participants were in favour. Costs
for the 10-15 year project are estimated at between €5 billion
to €7.5 billion.
RFF will launch complementary studies this year to
investigate three different scenarios: to reduce the journey
time between Paris and Nice to less than four hours

compared with five hours 33 minutes at present by extending the present line from Marseille to Nice
via Toulon; to serve Toulon and Nice on a separate line bypassing the centre of Marseille; or offering
direct access to Toulon and Nice by rapid regional links from the existing high speed line.
The studies will also consider possible extension of the project towards Italy, short-term improvements
to regional and freight services in the area, and the possibility of serving Cadarache, the European
home of the ITER reactor, which is designed to demonstrate the scientific feasibility of nuclear fusion.

France. SNCF, the French railways, have plans to build a new underground station for high speed rail
in the heart of Paris, in Place de la République. The project is mentioned in a document handed on by
SNCF to the Ile-de-France region, as part of the revision of the infrastructure and transport guidelines.
The Gare du Nord, Gare de Lyon and Gare Montparnasse main stations are close to saturation and it
is necessary to anticipate the traffic generated by the future high speed lines (Rhine-Rhone
connection, etc.). In addition, all Parisian stations are cul-de-sac, hardly compatible with through
traffic. The idea to put and end to the deadlock effect of the stations is to build a 5 km underground
link and the Gare de la République station between the Gare du Nord and Gare de Lyon stations. The
project would intersect with four of the five RER (regional express rail) lines and seven of the fourteen
metro lines.
The technical challenge would be to dig under the existing metro lines. The SNCF estimates the cost
of the tunnel to €1 billion (the cost per kilometre of tunnel in Paris is €120 to €200 million) and the cost
of the Gare de la République underground station to €500 million.
Indonesia. Japan's Nippon Koei and Sojitz Corporation are studying a plan to build a 70 km tunnel for
electric trains in the western coast of Sumatra. The underground track between Musi Rawas in south
Sumatra province and the province of Bengkulu in the western coast of Sumatra is estimated to cost
IDR4 trillion (US$400 million). The consortium would hold a survey of soil structure in that area this
month. Visit www.n-koei.co.jp/english, www.sojitz.com/en/index.html and www.tunnelbuilder.com,

Netherlands. A long tunnel
is under study to link the A6
and A9 highways in
southeast Amsterdam (see
dotted alignment on map), to
connect directly Almere,
Amsterdam and Schiphol.
The A6-A9 tunnel is one of
two alternatives that the
minister for transport, public
works and water
management will have to
choose from next summer.
The other solution is the
widening of existing roads
northwest of the A1 / A6
junction, the Gaasperdammerweg running right through southeast Amsterdam and a section of the A2.
The studies, like the environmental impact assessment, have just been completed. The A6-A9 option
is slighty preferable. Since the region is a green lung a tunnel seems to be the only acceptable
solution. This tunnel has been studied by Tunnel Engineering Consultants in 2005, with several
variants. Visit www.tec-tunnel.com
The basic principle is for a twin bored three-lane tunnel between the A1 / A6 junction and the A9, with
a length of 7.4 km, crossing the Vecht and Gein rivers, Amsterdam's Rijn canal and two railways.
Outer diameter would be 15 m. The design is being detailed to get a realistic cost estimate with a
deviation not exceeding 20%. The costs are estimated at €2 billion. The overall project would cost €4.5
billion for the road construction between Almere and Amstelveen. A first market consultation is

expected in 2008. Geology is mostly sand. The Centre for Tunnel Safety made requirements regarding
safety, such as doors every 250 metres. The ministry plans to write a functional description to estimate
the cost of safety-related technical choices like Promatect fire protection and other products. Visit

New Zealand. The
latest plan for
expanding access to
one of New Zealand's
most popular tourist
destinations involves
digging a tunnel from
the Routeburn road
near Glenorchy in
Mount Aspiring National
Park to the Hollyford
Valley road in Fiordland
National Park. The
NZ$150 million plan the latest of three
proposals for Milford
access - was unveiled
in Queenstown on 20th
December by Milford
Dart Ltd. Milford Dart
has applied for a concession for the venture to the Department of Conservation (DOC).
Two other proposals are also in the pipeline - a monorail through the Snowdon Forest to Te Anau
Downs linking with a one-hour coach trip to Milford and a 12.6 km gondola linking the Caples and
Greenstone valleys to exit at the Te Anau-Milford road before the Homer tunnel.
Forest and Bird said the latest plan would have the least environmental impact on other national park
users than either the monorail or the gondola. The proposed 10.2 km-long tunnel would be the longest
in New Zealand. The tunnel, to be known as the Dart Passage, would cut the total driving time
between Queenstown and Milford Sound from a 10-hour round trip to just four hours. Milford Sound
has become increasingly congested as its popularity with overseas visitors grows and the tunnel would
ease congestion at peak times by spreading the arrival of visitors over a much longer period. The
tunnel plan would see up to 40 diesel/electric hybrid coaches making the journey in two hours several
times a day.
If the DOC concession is granted, it is hoped the tunnel can be finished in time for the 2011 Rugby
World Cup. The tunnel would take three to four years to build while the planning process is expected
to take about two years. Visit www.milforddart.co.nz/information/media-release-20051220 to view

United Kingdom. The government is considering whether or not to build the Thames Tideway tunnel
to protect the river from wet weather discharges of sewerage overflows. The Thames suffers
considerably from untreated sewage overflowing from its ageing underground networks. Between 50
and 60 incidences occur annually amounting to an estimated 20 million cubic metres of untreated
sewage entering the river. This was brought into sharp focus last summer when 600,000 tonnes of
sewage was forced into the water in a single day killing thousands of fish.
For many years, the Environment Agency and others have argued that the situation could be resolved
by building the Thames Tideway - a 35 km-long interceptor tunnel which would run beneath the river
from Hammersmith in west London, capture the effluent from the combined sewer overflows, and
convey the discharges to the Crossness sewage works in east London. The Office for Water Services
(OFWAT) excluded the tunnel from its final price determinations meaning that Thames Water could
Page 3 of 12
E-News Weekly
2/2006
not afford to build it despite being allowed to raise prices by 24% over the investment period.
Now, a supplementary report published in November 2005 by the Thames Tideway Strategic Study
has been delivered to government recommending building the tunnel as the best solution out of the
options considered. Given that the tunnel, which would be of 7.2 m diameter, is likely to take at least
15 years to build, the report also considers extending the range of smaller scale interim measures to
provide short-term alleviation much sooner.
The latest report from the Strategic Steering Group, which follows a previous report released in
February 2005, finds that the tunnel had the highest net benefits in their cost benefit analysis of the
available options. The group calculated the cost of building at £1.5 billion with an annual operating
cost of £3.2 million. This translates into an average annual sewerage bill rise of between £40 and £45
over the level it would otherwise reach were the Tideway project not to be implemented. The majority
of the increase would take effect over the expected construction period. Visit

United States. Peak-period traffic at the Pennsylvania Turnpike's Allegheny mountain tunnel is
projected to be so heavy by 2025 that turnpike officials plan to dust off a study from six years ago
which investigated whether a bypass over the Somerset County mountain or a third tunnel would be
the better way to head off the congestion. The study was dropped in 2000, partly because the cost of
options ranged from $91 million to $150 million, but mostly because a hunting-fishing club and
environmentalists opposed a bypass, which included a 67 m-deep cut, creating a gorge in one of the
last continuous mountain ranges in Pennsylvania. A decision will be made no later than 2007 about
what to do but it will be at least another eight to 10 years before construction would start.
The turnpike is investing about $50 million to repair and upgrade the 1,830 m twin tunnel, 22.5 km
east of Somerset, and to rebuild and straighten the dangerous S-curves on the long westbound climb
leading to its entrance. The improvements will extend the life of the existing tunnels and make the
highway safer for the growing volume of vehicles. The average daily traffic through the Allegheny
mountain tunnel reached 30,648 vehicles in 2004, a 25% increase in 10 years. Many of the vehicles
are trucks.
The turnpike has other work under way or planned. A $6.9 million contract has been awarded to
replace the tunnel lights with brighter, more modern lights. Work is to be finished by fall 2006. Bids are
to be advertised in spring to upgrade the tunnel ventilation fans, housings and related equipment for
about $2 million. About $10 million has been set aside in the turnpike's 10-year capital plan to maintain
and repair the tunnel walls and ceilings, including an inspection to be done this year. Engineers are to
pay special attention to the ceiling of the westbound tunnel, built in the late 1930s, where a heavy wire
mesh was installed years ago to contain chunks of falling concrete. Visit www.paturnpike.com
United States. A planned $55 million stormwater tunnel designed to end flooding on both sides of the
San Francisco-Daly City border is planned to go directly under the county border. The proposed
project includes constructing a new tunnel, upgrading Daly City's stormwater infrastructure and
converting the canal to wetlands. The city is set to submit its draft plan this month. Once a plan is set,
the city will seek state and federal funds to proceed with the project.
The tunnel length of the project, still with no official name but most likely to be named Vista Grande
stormwater diversion tunnel, is 1,375.5 to 1,464 metres. The tunnel exterior diameter will be 4.57 m.
The concept is to divert upwards nearly 42.5 cu m/s. The project is still at conceptual stage and
conceptually work is expected to continue from present with construction completed by late 2011. The
expected date to invite tenders for construction is unknown. The tunnelling method is expected to be a
TBM. Other parameters like the planned lining technique and geology are also still to be determined.
The estimated price tag ranges from $52 to $55 million depending upon alignment. A third alignment is
being examined and the results are awaited. Visit www.dalycity.org
Focus on Lyon-Turin
France-Italy. The Lyon-Turin high speed link project comprises of three sections, both for freight and
passenger transport: the French section, from Lyon to Saint-Jean-de-Maurienne, managed by Réseau
Page 4 of 12

Ferré de France (RFF); the international section between France and Italy, from Saint-Jean-deMaurienne to Bruzolo, managed by Lyon Turin Ferroviaire (LTF); and the Italian section, from Bruzolo
to Turin, managed by Rete Ferroviaria Italiana (RFI). These three companies work in close
collaboration. LTF is jointly controlled by RFF (50%) and RFI (50%) and works under the responsibility
of an inter-governmental commission, chaired alternatively by France and Italy.
In January 2001, the French and Italian governments signed an agreement, which later became a
treaty when it was ratified by the parliaments of the two countries in 2002, to build a 53.1 km-long base
tunnel on the international section to link Saint-Jean-de-Maurienne in Savoy, France with Venaus in
Susa valley, Italy. This tunnel will be extended by the 12.2 km Bussoleno tunnel between Venaus and
Bruzolo.
In the first phase, LTF is responsible for the preliminary studies and the ground investigation works on
the international section (the Modane/Villarodin-Bourget, Saint-Martin-la-Porte and La Praz access
adits in France and the Venaus exploratory tunnel in Italy) and for making a proposal to the
intergovernmental commission related to the final design of the tunnel network, the location of the
structures, the foreseen financial cost and the construction methods so that the governments can
commence, in the second stage, the operational phase of the cross-border section.
In accordance with the January 2001 agreement, the studies and construction will be equally financed
by the two countires. The European Union is also contributing to nearly 50% in the financing. The
target cost of €13 billion has been endorsed by the French and Italian prime ministers during the
signature of a financial agreement in May 2004. The new line will enable greater mobility, cutting
journeys to just one hour 45 minutes to mo more than four hours 17 minutes today.
Access adits and exploratory tunnel
Work at the Modane/Villarodin-Bourget,
Saint-Martin-la-Porte and La Praz access
adits in France commenced respectively in
July 2002, March 2003 and October 2005.
Their lengths is respectively: 4 km, 2,050 m
and 2,572 m. These three drifts will make it
possible to go down to the heart of the
massif until the level of the future base
tunnel. At the end of these access adits,
investigation tunnels will be driven
horizontally. The three access adits are built
using the drill/blast method. These adits will
serve for access to start several drives
when excavating the base tunnel and for
ventilation, maintenance and rescue during
operation of the line.
In mid-May 2004, progress at the
Modane/Villarodin-Bourget adit had reached
1,086 m but LTF cancelled the contract with
the contractors due to a disagreement (read
E-News Weekly 28/2004). Razel, Bilfinger Berger and Pizzarotti were contracted in September 2005
to complete the 2,914 metres of 65-80 sq m tunnel. At the end of the adit, a 2,050 m 29-37 sq m
exploratory tunnel will be driven to the east. The new contractors have selected four Atlas Copco drill
rigs for the job (a WL3 C, a L2 C, a Boltec LC and a Diamec U6). Visit www.atlascopco.com
Razel, Bilfinger Berger and Pizzarotti had also secured the contract for the 80-100 sq m Saint-Martinla-Porte adit. As of early December 2005, 1,333 m had been excavated. The machinery used is an
Atlas Copco XL3 C jumbo, equipped with Secoroc drill bits, and two 435H bolting machines, also
supplied by Atlas Copco. The construction management has been commissioned to a joint venture of
Scetauroute, Antea and Alpina. The Saint-Martin-la-Porte reconnaissance gallery will be 1.5 km long
and of 32-43 sq m section.
Spie Batignolles TPCI, Sotrabas, Ghella and Cogeis are the constructors of the 80 sq m La Praz adit.
An announcement regarding the tunnelling and supporting machinery is imminent. Construction is
supervised by Schmidhalter & Pfammater Ingenieure (SPI) of Switzerland. The La Praz investigation
Page 5 of 12

tunnel will be 30 sq m in section for a length of 2 km. Read E-News Weekly 43/2005.
Tunnelling of the 7 km-long 6 m-diameter Venaus tunnel, with option for 3 more kilometres, should
commence in Cenischia valley next spring, using a Robbins TBM. The tunnelling contractors are CMC,
Strabag, Bentini Costruzioni, Cogeis and Geotecna. Construction will be managed by Geodata, SNCF
Ingénierie and Systra. However, protestors have been actively demonstrating against the project in
Susa valley. Read E-News Weekly 50/2005. Visit www.robbinstbm.com
International section
The final design of the cross-border section between France and Italy is under way to study in depth
all the aspects of the project: functional (operation, maintenance, safety), technical (civil engineering,
geology, equipment and environment), economic, legal and financial.
In addition to the above-mentioned adits and exploratory tunnel, the international section includes the
Saint-Jean-de-Maurienne station, the Maurienne-Ambin base tunnel, the Modane underground
station, bypass tunnels (in red on alignment below), cross passages every 400 m, the Avrieux
ventilation shaft, six ventilation stations, the Cenischia valley viaduct, the Bussoleno tunnel and the
Bruzolo facility.
To be driven at 570 to 750 metres above sea level, the Maurienne-Ambin base tunnel will be formed
by two 53.1 km parallel single-track tubes under a maximum cover of 2.5 km. It will be designed and
built to carry all types of traffic (freight trains, trucks on trains and passenger trains). The maximum
slope will be 12‰. The inner diameter will be 4.2 m.
The tunnel will be bored from five accesses, with 16 drives using the drill/blast method and open face
TBMs. The Lyon-Turin high speed link will generate 17.5 million cubic metres of excavated materials.
This represents the equivalent of six Kheops pyramids. More than a third will be processed to produce
concrete additives.

Pakistan. Pakistan received only two bids following an international competitive bidding for civil works,
mechanical works, hydraulic steel works and electrical works for the 969 MW Neelum-Jhelum
hydropower project. The two bids are from China International Water and Electric Corporation
(CIWEC) and China Mechanical Electric Company (CMEC). The project will cost $1.6 billion. The
Water and Power Development Authority (WAPDA) is currently evaluating the bids.
About 98% of the the Neelum-Jhelum hydropower project structure would be underground, including a
41 km tunnel, powerhouse and transmission system, and the remaining 2% (inlet and outlet of the
water tunnel) would be at grade. The tunnel would be about 300 metres below the riverbed. On
completion, the Neelum-Jhelum project would protect Pakistan’s priority rights over Neelum waters,
besides providing cheap electricity.
Pakistan’s proposed project will be built on the Neelum river in Azad Kashmir, which is part of the
Pakistani-administered part of Jammu & Kashmir. The Neelun river is called in India Ganga river on
which India is building the Kishanganga hydropower project. Pakistan considers construction of the
Kishanganga hydropower project by India a violation of the Indus Waters Treaty of 1960. India is
reported to have completed 75% of a 22 km diversion tunnel of the project.

World Digest of Contract Awards
France. HSBC, Bank of Scotland Corporate - part of HBOS - and Calyon, the corporate and
investment banking arm of Crédit Agricole, are providing a total of €940.5 million to French consortium
Adelac, headed by Bouygues, which will design, build and run a new motorway across the French
section of the Alps. All three banks are contributing equally towards the costs.
The current initiative sees the A41 north stretch for 19 kilometres between Annecy and Geneva in the
Rhône-Alpes region in France. This particular motorway is being touted as a safe way to travel to
Switzerland as the current route is treacherous at best and is accident-prone. The motorway also
includes a tunnel that runs through Mont Sion for 3 km.
Motorway operator AREA, French construction group Bouygues and the Caisse d'Epargne et de
Prévoyance des Alpes bank are the joint owners of Adelac, which is supposed to begin construction
this year. The venture is supposed to be completed in five years time. Revenue will be generated by
charging toll as well as fees for using the gateway. Visit www.tunnelbuilder.com, fr/56.
Spain. Tecsa and Construcciones Galdiano bagged a €21.6 million contract to build section San

United Kingdom. The cost of a 250 m tunnel to tackle chronic traffic congestion at a notorious
Sandwell railway crossing has soared to £18 million, and it will not open until at least 2009. Work on a
relief road under Tipton's Owen Street crossing was originally supposed to cost less than half that and
start several months ago. Now Sandwell Council says unforeseen ground conditions - including
mineshafts and geological faults - and increases in land values has lead to an increase in costs. The
proposed scheme involves complex construction methods in order to avoid disruption to the railway.
Sandwell Council is awaiting approval from the government for the scheme, which is unlikely to be
known until the spring. The contractor was announced in June 2004 (read E-News Weekly 24/2004).

Australia. The Mandurah railway in Perth might not be operating by its April 2007 deadline because of
delays in digging a 770 m twin bored tunnel. The problems with construction of the tunnel under
William street, which is already three to seven weeks behind schedule, have forced the Public
Transport Authority (PTA) to draw up plans based on a revised timetable for other aspects of the
project. The first leg of the tunnel from the Esplanade missed the two-week Christmas shutdown on
22nd December and is now due for completion in late January or early February. Read E-News Weekly

China. The Asian Development Bank (ADB) said on 17 December it has approved US$208 million in
a loan for a 64 km-long expressway project in central China's Hunan Province. The Jishou-Chadong
expressway aims to spur economic growth in Hunan's rural and mountainous Xiangxi autonomous
prefecture, where economic growth has been stunted due to limited road access, by linking the area to
the Changsha-Chongqing highway, one of the key traffic passages in the western regions.
The project covers one city and four counties in which 80% of the population lives in rural areas and
more than three quarters of the people are ethnic minorities.
The project involves construction of 64 km of toll expressway from Jishou to Chadong, including a

large suspension bridge, 13 tunnels, 36 other large bridges, interchanges, toll stations, and service
areas.
The total project cost is US$519.51 million, with partial financing from China's Ministry of
communications, the Hunan provincial government and the China Development Bank. The project will
be managed by the Hunan provincial communications department.
China. A section of the third ring road East
running past Beijing's central business district
caved in at 2 a.m. on 2nd January, rupturing a
sewage pipe and flooding a construction site of
metro Line 10 which is under construction for the
2008 Olympics. Labourers working on Line 10
were evacuated and no casualties were reported.
It is too early to conclude that the cave-in was
caused by the metro construction site.
Another leak from an old waste water pipe caused
a tunnel on the same Line 10 to cave in last
November, leaving a 10 m-deep 400 sq m pit. The
first phase of Line 10, which is 26.2 km long with 22 Picture 1: A waste water pipe broke in the third ring road

Shanghai also experienced woes building its metro when a tunnel under the city's Huangpu river
collapsed, causing nearby land and buildings to sink and flooding in nearby areas. Three officials were
arrested in connection with the Shanghai accident, which cost the city CNY850 million ($142.8 million).

Ireland. Conciliation talks over a €444 million overrun in the construction of the Dublin port tunnel
have collapsed. The talks took place between Dublin City Council and the Nishimatsu / Mowlem /
Irishenco consortium. Press reports say that they took place after the consortium made two claims for
extra payments of €354.6 million and €89.5 million. If successful, these would have pushed the total
bill for the behind schedule project to €1.3 billion.
The €444 million involved is just €4 million less than the entire original estimated cost of the project.
With conciliation talks having failed, the matter is now due to be sent to a dispute adjudication board.
This board is made up of one representative of Dublin City Council, one member of the contractors
and an agreed independent member. If the board fails to find an agreement between both sides it will
be sent back into conciliation. If this then fails it will be referred to adjudication as both strongly
opposed sides attempt to prevent the dispute spilling into the courts.
The opening of the tunnel was originally set for early 2005. However, problems on the contract pushed
the date back to July last year. This deadline was also missed and a summer date for this year was
set. Dublin City Council is "confident" the tunnel will be open this summer and that it could even be
ready as soon as May.
Dublin City Council expects to pay out over €1.38 million to residents living above the Dublin port

Russia. Bamtonnelstroy of Krasnoryarsk has launched their new 9.5 m-diameter single shield hard
rock TBM, dubbed Martha, to drive the 2,300 m Krolsky tunnel project through mostly highly-abrasive
metamorphic slate and argillite as well as some limestone and granite. The TBM is expected to run
two 10-hour daily shifts and hole out in October 2006. A launch ceremony was held at the Krolsky site
in Siberia in November.
The Lovat also designed and supplied a segment plant (including forms, segment carousel and plant
design/layout) for the manufacture of the precast tunnel lining elements. They also provided technical
services for the assembly, testing and commissioning of the TBM and will give Bamtonnelstroy
technical assistance for the first 200 metres of tunnel.
This TBM features an hydraulically-driven cutting head which includes seven ground conditioning
injection ports that allow the operator to inject conditioning agents (foam, polymer, water) to reduce
friction and wear. The cutting head face and edge are protected with chromium carbide plating. It has
a total installed power of 2,100 kW delivered by seven electro-hydraulic power and has been supplied
with an initial dressing of 62 disc cutters. Mounted on the motor plate and positioned at the centre of
the bearing is the mucking ring which collects the excavated material from the excavation chamber.
The belt conveyor is positioned at the centre of the mucking ring for loading of the excavated material.
The conveyor is a two-stage, variable-rate and reversible equipment. The primary belt is 20 m long
and the secondary belt is a further 73 m. Each section is capable of discharging 800 tonnes per hour.
The system deposits the rock into rail-mounted muck cars for removal from the tunnel. Lovat designed
and manufactured this TBM in nine months, three months ahead of schedule. Visit www.lovat.com and

United Kingdom. Drivers are facing another year of disruption after a £9 million project to upgrade the
Clyde tunnel in Scotland hit a major snag. Cracks have appeared on the tunnel's new cladding.
Contractors have said a hitch means one lane in the tunnel will have to stay closed at nights until
November 2006 instead of the original completion date of this October - 13 months longer than
planned. The delay comes after the job of spraying fire-resistant concrete cladding in the first of the
two tunnels had to be stopped when a test section cracked. Contractor Byzak scrapped plans for a
further test and is investigating alternative designs. Unless Byzak can come up with reasons to justify
an extension to the contract, it will be hit with a bill for £2,000 for every day the work is delayed - a bill
of around £730,000. Since work began, one of the two tunnels has been closed seven days a week
between 7 p.m. and 6 a.m. The closures will continue until the project is finished. Read E-News
Weekly 43/2004 & 44/2003.
United States. The Pennsylvania Department of Transportation (PennDOT) plans to give the
downtown side of the Liberty tunnels in Pittsburgh a face-lift in a couple of years. Early signs indicate
the concrete underneath the northern portal is crumbling, prompting PennDOT to order an inspection
and set a plan in motion to repair the damage at an estimated cost of $20 million. The steel panels
covering the concrete are heavily worn and need to be replaced. PennDOT discovered the
deteriorating steel about a year ago and hired Gannett Fleming for $246,000 to do the evaluation. The
consultant will determine whether the concrete underneath the steel panels is damaged and how
much has to be spent to fix the deterioration. Dismantling the Cor-Ten steel facade at the portals
started on 3rd January. The facade removal will cost between $60,000 and $75,000. The steel facade
was installed in 1975. Removing the panels is budgeted to cost up to $75,000.
Gannett Fleming's analysis is expected to be completed in March. Work to repair the concrete and
replace the face is not planned to begin until at least 2007. The steel panels on the other end of the
tunnel does not appear to be in as poor condition. The tunnel assessment also will include looking at
its ventilation, electrical and lighting systems since PennDOT plans to repair and modernise all but the
tunnel floors, which were replaced in 1996. The design of the new facade has yet to be decided.
45,000 motorists use the 1,796 m-long tunnel daily. Visit www.dot.state.pa.us
United States. The century-old railroad tunnel connecting the Simi and San Fernando valleys is
scheduled to undergo about $7 million worth of renovations to make it safer during earthquakes. The
Southern California Regional Rail Authority said the concrete lining needs to be reinforced with grout
and bolts. Work is expected to start in March and last about nine months. The tunnel is used
throughout the day by freight, Amtrak and Metrolink trains. There are actually three railroad tunnels in
that area - Tunnels 27 and 28 in Chatsworth, and Tunnel 26, the longer, 2,247 m tube between
Chatsworth and Simi that is getting the makeover.
DMJM+Harris, Milbor-Pita & Associates and PanGeo prepared the design and bid documents of the
seismic upgrade project regarding Tunnel 26. The rail authority, which operates Metrolink, is
evaluating bids for the renovation (contract C3084-06). For more, contact Michael McGinley, director
engineering and construction, e-mail [email protected] or Gray Crary, assistant director of
engineering and construction, e-mail [email protected]. Visit www.metrolinktrains.com
