JA NEWS
This past fall, Jacobs Associates opened
the doors to our newest branch office in
Melbourne, Australia. The expansion solidifies
our fi rm’s presence in the region and positions
us to better provide tunnel and underground
engineering for water, wastewater, and transportation
projects throughout Australia and New
Zealand.
The Melbourne office currently supports two
ongoing projects in the region—the Northern
Sewerage Project Stages 1 and 2 in Melbourne
and the Boggo Road Busway in Brisbane. These
projects are the latest in Jacobs Associates’ history
in Australia, which dates back to our founder
J. Donovan Jacobs’ involvement with the
Snowy Mountains hydroelectric tunnels in the
1960s. Since that time, we have provided service
on over twenty major contracts in the region,
including rail transit tunnels for Melbourne
City Loop in the 1970s, the M5 East Motorway
in Sydney in the 1990s, and the Melbourne
CityLink tunnels in the 1990s.
Construction is underway on the Lenihan Dam Outlet Modifi cation Project, undertaken by Santa Clara Valley Water District at the Lexington Reservoir in Northern California. The project
will restore the outlet works to their original operating capacity. Jacobs Associates designed the new outlet tunnel and pipeline, and is providing on-site support during construction.
Jacobs Associates' new Melbourne offi ce is located in the
popular Docklands area.
SHAWN SPRENG
Just south of Los Gatos, California and within
three kilometers of the San Andreas Fault, new
outlet works are being constructed for Santa
Clara Valley Water District’s Lenihan Dam at
the Lexington Reservoir.
The project will more than quadruple the current
discharge capacity, from 70 cubic feet per
second to the original operating capacity of 410
cubic feet per second. Releases from the reservoir
have been restricted because of damage to the
current outlet.
Jacobs Associates designed the new outlet tunnel
and pipeline and is providing on-site support
during construction, which began in late 2007.
The 2,035-foot-long tunnel is a straight-legged
horseshoe shape with an excavated width and
height of 14 feet and 12.5 feet respectively. It is
being excavated by conventional roadheader and
drill-and-blast methods.
The regional geology along the tunnel alignment
is a Franciscan melange—a chaotic mixture
of hard and resistant blocks embedded in a
crushed and sheared matrix. The blocks generally
are moderately jointed to blocky and seamy
greywacke and serpentinite with some greenstone
and chert, and the matrix material is crushed and
clayey altered shale and serpentinite.
the excavated space can remain “standing”
without support).
• Squeezing ground conditions which may
cause the tunnel sidewall and invert to move,
either immediately or weeks after excavation,
which can cause the tunnel supports to
deform and fail over time.
• Blocks of strong, hard, highly abrasive rock
with moderately spaced joints require drilland-blast
excavation.

challenging due to several factors:
• Weak and friable rock units have low standup
time when below the groundwater level,
leading to difficulty when installing support
(stand-up time is the length of time that
• Mixed ground conditions consisting of
boulders of closely fractured, strong, hard
rock embedded in a weak, clayey and gravely
matrix require both drill-and-blast and
roadheader excavation in one face.
For the project design, Jacobs Associates analyzed
geological and groundwater data using numerical
and empirical methods, then created tunnel
support and groundwater control systems that
can be used flexibly in three types of ground. The
ground types vary from Type 1 (most stable) to
Type 3 (least stable).
The initial support system was designed to be
adaptive to accommodate highly variable ground
conditions. All three support types employ
W6x25 steel sets placed at 4 feet on center and a
cast-in-place reinforced concrete invert. Type 1
support includes up to 3 inches of fiber-reinforced
shotcrete to control localized instabilities. Type 2
and 3 supports include 6 inches and 9 inches of
fiber-reinforced shotcrete, respectively, to control

PRINCIPAL'S MESSAGE
Nothing
Comfortable about
Cost Estimating
One of the thorniest tasks we undertake for our
clients is that of recommending or validating
the project budget. If the project is one of many
in an owner’s capital improvement program, it
is likely competing for a limited pool of funds,
so it demands an accurate cost forecast. If the
budget is too low the project will run out of
funds before
construction is
complete, but if
it’s too high it
takes resources
away from other
projects in the
program.
It’s a familiar
issue: our clients
ask us to help
them commit to
John M. Stolz, PE
an authoritative
cost for an asyet
undefi ned
project with as-yet unknown impacts to the
environment and community. Furthermore,
the cost can’t be a moving target, because it’s
usually impossible to return for additional
funding. A realistic budget must be established
and adhered to from the outset, and it usually
must be established when we know the least
about the project. Often the initial processes
that are supposed to help us better defi ne cost,
such as selecting a fi nal alignment and making
preliminary subsurface investigations, seem to
raise more cost-related issues than they address.
Establishing a realistic cost estimate under these
conditions calls for a skill set that isn’t widely
available in the underground construction
industry. For one, the skill is best developed
under the employment of a heavy construction
contractor whose livelihood depends on accurate
competitive bids. But it also requires other
technical abilities like an aptitude for matching
cost-effective design solutions to state-of-the-art
construction means and methods. It requires
an up-to-date, practical understanding of how
the work is likely to be constructed under a
competitively bid contract. And it requires what
might appear to be a prescient awareness of
potential risks endemic to the industry.
Improving Contract Practices
Published this month by the Underground
Construction Association of the Society for
Mining, Metallurgy, and Exploration (UCA
of SME), Recommended Contract Practices for
Underground Construction is the culmination
of four years of effort put toward defi ning some
best practices to improve the development of
contract documents and the administration of
construction contracts for underground projects.
The manual was undertaken in response to
the increase in the extent and sophistication of
our use of underground space, which has been
mirrored by a noticeable lack of development in
contracting practices.
When faced with similar circumstances in
1974 industry insiders prepared the Better
Contracting for Underground Construction
manual. The manual recommended a number
of improvements to underground contracting,
many of which are in use today.
The goals of these
recommended contract
practices are better
relationships, better
contracts, and projects that
are more cost-effective for
owners and more profitable
for contractors.
The new book builds upon the work
done in 1974, and expands it by making
recommendations for better contracting
practices in eleven separate areas: relationships
of the parties, project planning, subsurface
conditions, risk management, design and
construction management, cost estimating,
schedules, pricing and payment, contracts,
changes, and dispute resolution.
Each chapter offers a comprehensive overview
of one of these topics, then discusses its impact
on contracting and presents the perspectives of
owners, design engineers, contractors, and/or
other stakeholders.
The twelve authors of Recommended Contract
Practices are each acknowledged authorities in
a different aspect of underground construction
contracting and delivery. The recommendations
made reflect their experience as well as industry
consensus on best practices, as established
TBM Arrives at Northern Sewerage Project
during conversations and workshops with
members of the industry.
JUST ANSWERS
SME
The National Academy of Sciences' 1974 manual, left, inspired the Underground Construction Association of the Society for
Mining, Metallurgy, and Exploration (UCA of SME) to commission an update, out this May. Recommended Contract Practices
for Underground Construction (at right) covers topics ranging from relationships and planning to dispute resolution.
William W. Edgerton (Jacobs Associates),
chaired the steering committee responsible for
developing the new manual. The committee
members were Lok W. Home (The Robbins
Company), James E. Monsees (Parsons
Brinckerhoff ), Edward S. Plotkin (independent
consultant), Richard E. Sage (Sound Transit),
David Hatem (Donovan Hatem LLP), Robert
Miller (Allied North American Insurance
Brokerage), and the late Robert A. Pond
(Frontier-Kemper Constructors).
Copies of Recommended Contract Practices are
available in early May from SME at www.

PROJECT UPDATE
Estimating is more than just “thinking the job
out on paper.” The estimator has to know how
it would be built in real life, orchestrating crew
sizes, equipment spreads, and production rates
with community and environmental constraints
to optimize construction of the project.
The estimating process demands a fiduciary
duty to our clients that we take very seriously;
we neither infl ate our engineer’s estimates to
provide a reserve cushion of funds nor lowball
costs to match an existing budget. Our clients
receive no value unless the engineer’s estimate
reflects our best assessment of the expected
amount of the low bid, based on the project’s
technical and contractual requirements.
Because there is so little wiggle room and so
much at stake, we advise our clients to add our
recommended reserve for the current market and
bidding climate and risks that will materialize
during construction.
That is the only way to truly serve our clients’
best interests, but like contractors, we sure have
a lot of nervous estimators on bid day.
Sincerely,
John M. Stolz, PE
Principal and Corporate Secretary
John’s 29-year career has spanned the contracting,
construction management, design, and dispute
resolution side of over a hundred projects in the
underground construction industry. While he and
his wife Maria are just getting to know their fi rst
granddaughter, Talia Yasmine, they have already
determined that she will contribute immeasurably
to the advancement of mankind.
This Herrenknecht earth pressure balance tunnel boring machine (left) is one of three machines that will be used in the construction of the Northern Sewerage Project near Melbourne,
Australia. When complete, the project will signifi cantly increase sewerage capacity in the growing suburban areas north of Melbourne. The project involves the construction of 12.4 kilometers
of tunnel and eight shafts, ranging in depth from 25 meters to 64 meters.
MARK E. TRIM, P.E.
The Northern Sewerage Project (Melbourne,
Australia) will employ three tunnel boring
machines (TBMs) to excavate 12.4 kilometers
of tunnel—part of a large upgrade of one of
Melbourne’s aging, under-capacity trunk sewers.
The project’s two phases are a joint effort of
Melbourne Water and Yarra Valley Water.
In early April, the fi rst of the three TBMs
arrived on-site. The 3-meter-diameter
Herrenknecht earth pressure balance TBM,
named Victoria by local school childern,
was lowered into the De Chene shaft launch
chamber on April 19, 2008.
Victoria will be used for three different drives
on NSP, excavating a total of 3,900 meters of
tunnel. During her time on NSP, Victoria will
be chewing through predominantly medium
to highly weathered, low to medium strength
Silurian (sandstone/siltstone). Steel-fiberreinforced
precast segments will be placed
behind the machine to provide short- and longterm
ground support. Victoria is expected to be
mining by the fi rst week of June 2008.
The second earth pressure balance machine, a
4-meter-diameter TBM by Herrenkecht, arrived
on-site in May 2008. This 4-meter diameter
machine will be used for two drives on NSP,
which will total 4,735 meters of tunnel. The
third and fi nal TBM will arrive in July 2008.
This machince is a Robbins hard rock TBM with
a cut diameter of 3 meters. The Robbins TBM
will be used to excavate 3,150 meters of basalt on
NSP Stage 2.
Jacobs Associates, along with joint venture
partner Sinclair Knight Merz (SKM), are
providing on-site support to Melbourne Water
and Yarra Valley Water during construction.
Connell Wagner is providing project
management services and John Holland Group
is the contractor for both stages of the project.
The project is expected to be completed in 2012.
Mark's service on the NSP project began with
tunnel design for Stages 1 and 2 in 2006. He now
provides on-site support during shaft and tunnel
construction. Mark co-presented a paper on the
fi nal lining selection for NSP at the May 2008
Australian Tunneling Conference.

heavier ground loads and possible squeezing. In
all types, a reinforced concrete invert—12 inches
thick at the sides and 24 inches thick at the
centerline—is used to prevent invert heave and
provide resistance to bending moments from longterm
groundwater loading.
To date, the tunnel excavation has advanced
approximately 1,350 feet. So far, more Type 1
support has been installed than was anticipated.
Monitoring devices have been installed inside
the tunnel to monitor deformations of the tunnel
sidewalls, and measured convergence has not
exceeded 1.3 inches at monitoring locations.
NEW WIN
Reopening the Cal Park Hill Tunnel
Re-opening the Cal Park Hill Tunnel – a
partially collapsed former railroad tunnel,
measuring some 1,100 feet long – for bicycle,
pedestrian, and passenger rail shared use will
close the gap between San Rafael and Larkspur
in Marin County, Northern California. This
high-profi le project will provide many low-impact
transportation options for the County and
hopefully lessen traffic congestion in the I-580 /
Highway 101 Greenbrae Corridor.
After a difficult decision, the County of Marin
announced Jacobs Associates as the fi nalist fi rm
to provide construction management (CM)
services. This win extends Jacobs Associates’ history
of providing tunnel rehabilitation services
to Marin County. Such past projects include
the Fort Barry-Fort Baker Tunnel, Alto Tunnel,
Porteous Tunnel, and Cal Park Hill Tunnel (in
a design capacity). Jacobs Associates' subcontractors
include EPC Consultants and Inspection
Services Inc.
Construction of this multi-use pathway involves
six main construction elements:
ESCSO
Tunnel rehabilitation – excavation and reconstruction
of the collapsed sections, excavation
of the tunnel invert to accommodate future rail,
as well as replacement of the existing tunnel
support.
Installation of pathway structures, fi nishes,
utilities and systems inside the tunnel.
Permanent excavation support of slope cuts for
the pathway outside the tunnel.
Construction of mechanically stabilized embankments
for the pathway outside the tunnel.
Removal of existing rail bridge and installation
of a new prefabricated pedestrian bridge.
Corridor-wide pathway construction.
In addition to these responsibilities, Jacobs
Associates will advise Marin County during the
pre-bidding and bidding phases.
One of the main construction challenges ahead
is the issue of tunnel support. Excavation of collapsed
areas requires sequential excavation with
pre-support in disturbed ground to minimize
further ground loss. This is risky, specialized
work, and procuring a qualified contractor will
be a key success factor.
The rehabilitation of the Cal Park Hill Tunnel’s
existing tunnel support will occur in an
area with limited ground cover adjacent to the
existing U.S. 101 road cut. This requires timely
and accurate primary ground support to prevent
loss of ground. In addition to U.S. 101, nearby
structures and infrastructure could be adversely
impacted by construction. As the CM prime
and fi rst point of contact for construction activities,
Jacobs Associates will need to assure these
key stakeholders that nearby structures will be
protected from loss of ground.
Estimated to cost around $18.5 million, construction
of the Cal Park Hill Tunnel Rehabilitation
Project should kick off in the summer
of 2008. The construction effort is expected to
take about 18 months. And the rehabilitated
Cal Park Hill Tunnel should open to the public
in late 2009.
To date, a total of 40 feet of Type 3 support
has been installed in two locations: one as a
precautionary measure in a reach of sheared and
clayey ground, and one where the installed Type 1
support displayed visible signs of distress with an
estimated 1 to 2 inches of localized displacement at
the lower sidewall.
Jacobs Associates will continue to provide on-site
engineering support until the completion of
construction, projected for October 2009.
Shawn has lent his geotechnical and design
expertise to the Lenihan project since 2005, and is
now serving as the on-site design engineer. He will
co-present a paper on the design and construction
of the Lenihan Tunnel at the U.S. Rock Mechanics
Symposium (ARMA) later this summer.
