Bay Tunnel Breaks Ground
Subsurface Exploration and Ground Characterization Services
On Friday September 24th, the San Francisco
Public Utilities Commission (SFPUC) officially
broke ground on the Bay Tunnel project,
marked by a ceremony that took place on the
Ravenswood construction site in East Palo Alto
next to the marshlands of San Francisco Bay.
This 5-mile-long (8-km) tunnel is the centerpiece of the SFPUC’s $4.6 billion project to
overhaul the Hetch Hetchy water system. It is
also the first bored tunnel under San Francisco
Bay. Construction of the Bay Tunnel is scheduled for completion in 2015. The new tunnel
will replace the aging pipeline infrastructure
built in the 1920s and 1930s that traverses
the Bay on wooden trestles and will provide
seismic and delivery reliability after a major
earthquake for about 2.5 million customers in

Part II of BIM Series
BIM CAN MAKE A DIFFERENCE
UNDERGROUND
Building Information Modeling (BIM) has
traditionally been the domain of the general
building market because of its early adoption
by owners like the U.S. Government General
Services Administration. Because of BIM’s success, however, owners in other markets are now
starting to request it on their projects, including
those in the underground construction market.
BIM underground has some unique advantages over BIM for buildings. In general, heavy
civil projects have larger economies of scale,
meaning small tweaks to design and approach
early in the process have a greater influence
on a project’s overall cost. This, coupled with
the larger margins associated with the risk to
perform the work, makes the underground
market fertile soil for the predictive characteristics inherent in BIM.
Prior to joining Jacobs Associates I had the
opportunity to implement BIM on a variety of
underground projects as a consultant. Here is
a brief description of two projects where BIM
added value to the design coordination and
construction process:
MILWAUKEE HARBOR SIPHONS
Three-dimensional models were created to
coordinate the layout and fabrication of largediameter piping, both on the surface and underground. Underground the model was also
used to verify survey control and excavated
limits to ensure proper clearances were maintained. On the surface, the model was used to
verify pipe routing and check for interferences
Section through vault area showing
primary support and transitions.

and underground piping shown.

with other structures, including shaft support
of excavation, pipe cradles, thrust blocks,
valve chambers, and pile locations. During
this process multiple pile locations were found
to be in conflict with pipe routes and were
caught before pile driving began. Excavation,
concrete, and backfill quantities were also derived from the model once the final layout was
determined. The value came from assembling
all the components early in the process, which
gave both the designer and contractor time
to address coordination problems prior to the
commitment of field resources.
CLAREMONT TUNNEL SEISMIC UPGRADE
A key to this water supply project was the design
and construction of the vault area. The vault
increases protection as the water supply crosses
the Hayward fault in the San Francisco Bay
area. All the major permanent and temporary
construction features were modeled for this
area for the purpose of design coordination,
constructability review, and sequencing. As
with the Milwaukee Harbor Siphons project, the
model’s primary function was to marry contract
design with contractor means and methods to
simulate the work months in advance of physical construction. The model streamlined the
construction process and reduced the risk of
changes and claims from the contractor.
Despite BIM’s association with the aboveground building market, the tools and approach
can be adopted for use underground. Each
market has unique characteristics that place
different demands on the technology. And yet in
both markets, the value comes from identifying
change when change is inexpensive to make. Or
perhaps better said, “Measure twice, cut once.”

than 10 years of experience with 3D modeling

Too Small to Prime?
It was about five years ago when one of our best
clients told me “Dan, we’d love to give you the
job, but Jacobs Associates doesn’t have deep
enough pockets.” At the time this was good
advice. It reflected our clients’ and our firm’s
general belief about what was needed to deliver
a large project. However, since that time we’ve
worked with firms that have deep pockets as
well as firms with no pockets, delivering some
pretty large projects. Time and again, when
challenges have come up, particularly unanticipated challenges, the ability to solve the
problem has been based on access to talented
staff, not access to a bank account. Because of
this we spend far more time focusing on adding to or training our staff than on financial
performance. Earlier this year, the same client
who told me five years back we’re too small
selected us to prime one of its more complex
projects, choosing Jacobs Associates over two
firms more than 10 and 20 times our size, as
measured by Wall Street. This win confirmed
our belief that while deep pockets are important in finance, depth of and access to talent are
what matters in engineering.

After 27 months of design, a 12 month hiatus,
and 24 months of construction, the San Diego
County Water Authority’s Mission Trails Pipeline
Tunnel and Vent Demolition (MTPT) project is
essentially complete, with the final walk-through
conducted at the end of September. Eventually,
the project will deliver water from the existing
Second San Diego Aqueduct to a future flow
regulatory structure and back into the Second
Aqueduct, thereby protecting the existing aqueduct from potential hydraulic surges.
Located in the Mission Trails Regional Park,
one of America’s largest urban parks, the $28
million MTPT project required construction of
a 92-inch-diameter (2,340-mm) welded steel
pipeline. This involved developing two portals;
two 10-foot-wide (3-m) horseshoe tunnels totaling 4,500 feet (1,372 m); two shafts up to 150
feet (46 m) deep; upstream and downstream
connections to the existing Second Aqueduct;
and demolition of existing pipeline and vent
structures between the shunt connections.

Despite the significant environmental and

was successfully completed ahead of schedule
and under budget. Community issues and complaints that arose were dealt with swiftly and
to the satisfaction of the affected community

Building Information Modeling (BIM) has
traditionally been the domain of the general
building market because of its early adoption
by owners like the U.S. Government General

Prior to joining Jacobs Associates I had the
opportunity to implement BIM on a variety of

a brief description of two projects where BIM
added value to the design coordination and

MILWAUKEE HARBOR SIPHONS
Three-dimensional models were created to

used to verify survey control and excavated

of excavation, pipe cradles, thrust blocks,
valve chambers, and pile locations. During
this process multiple pile locations were found
to be in conflict with pipe routes and were
caught before pile driving began. Excavation,
concrete, and backfill quantities were also derived from the model once the final layout was
determined. The value came from assembling
all the components early in the process, which
gave both the designer and contractor time
to address coordination problems prior to the
commitment of field resources.

A key to this water supply project was the design

increases protection as the water supply crosses
the Hayward fault in the San Francisco Bay
area. All the major permanent and temporary
construction features were modeled for this
area for the purpose of design coordination,
constructability review, and sequencing. As
with the Milwaukee Harbor Siphons project, the
model’s primary function was to marry contract
design with contractor means and methods to
simulate the work months in advance of physical construction. The model streamlined the
construction process and reduced the risk of
changes and claims from the contractor.
Despite BIM’s association with the aboveground building market, the tools and approach
can be adopted for use underground. Each
market has unique characteristics that place
different demands on the technology. And yet in
both markets, the value comes from identifying
change when change is inexpensive to make. Or
perhaps better said, “Measure twice, cut once.”

Too Small to Prime?
It was about five years ago when one of our best
clients told me “Dan, we’d love to give you the
job, but Jacobs Associates doesn’t have deep
enough pockets.” At the time this was good
advice. It reflected our clients’ and our firm’s
general belief about what was needed to deliver
a large project. However, since that time we’ve
worked with firms that have deep pockets as
well as firms with no pockets, delivering some
pretty large projects. Time and again, when
challenges have come up, particularly unanticipated challenges, the ability to solve the
problem has been based on access to talented
staff, not access to a bank account. Because of
this we spend far more time focusing on adding to or training our staff than on financial
performance. Earlier this year, the same client
who told me five years back we’re too small
selected us to prime one of its more complex
projects, choosing Jacobs Associates over two
firms more than 10 and 20 times our size, as
measured by Wall Street. This win confirmed

Cryderman mucking inlet shaft.
After 27 months of design, a 12 month hiatus,
and 24 months of construction, the San Diego
County Water Authority’s Mission Trails Pipeline
Tunnel and Vent Demolition (MTPT) project is
essentially complete, with the final walk-through
conducted at the end of September. Eventually,
the project will deliver water from the existing
Second San Diego Aqueduct to a future flow
regulatory structure and back into the Second
Aqueduct, thereby protecting the existing aqueduct from potential hydraulic surges.
Located in the Mission Trails Regional Park,
one of America’s largest urban parks, the $28
million MTPT project required construction of
a 92-inch-diameter (2,340-mm) welded steel
pipeline. This involved developing two portals;
two 10-foot-wide (3-m) horseshoe tunnels totaling 4,500 feet (1,372 m); two shafts up to 150
feet (46 m) deep; upstream and downstream
connections to the existing Second Aqueduct;
and demolition of existing pipeline and vent
structures between the shunt connections.

was successfully completed ahead of schedule
and under budget. Community issues and complaints that arose were dealt with swiftly and
to the satisfaction of the affected community

JUST ANSWERS by Eric Westergren
Part II of BIM Series
BIM CAN MAKE A DIFFERENCE
UNDERGROUND
Building Information Modeling (BIM) has
traditionally been the domain of the general
building market because of its early adoption
by owners like the U.S. Government General
Services Administration. Because of BIM’s success, however, owners in other markets are now
starting to request it on their projects, including
those in the underground construction market.
BIM underground has some unique advantages over BIM for buildings. In general, heavy
civil projects have larger economies of scale,
meaning small tweaks to design and approach
early in the process have a greater influence
on a project’s overall cost. This, coupled with
the larger margins associated with the risk to
perform the work, makes the underground
market fertile soil for the predictive characteristics inherent in BIM.
Prior to joining Jacobs Associates I had the
opportunity to implement BIM on a variety of
underground projects as a consultant. Here is
a brief description of two projects where BIM
added value to the design coordination and
construction process:
MILWAUKEE HARBOR SIPHONS
Three-dimensional models were created to
coordinate the layout and fabrication of largediameter piping, both on the surface and underground. Underground the model was also
used to verify survey control and excavated
limits to ensure proper clearances were maintained. On the surface, the model was used to
verify pipe routing and check for interferences

with other structures, including shaft support
of excavation, pipe cradles, thrust blocks,
valve chambers, and pile locations. During
this process multiple pile locations were found
to be in conflict with pipe routes and were
caught before pile driving began. Excavation,
concrete, and backfill quantities were also derived from the model once the final layout was
determined. The value came from assembling
all the components early in the process, which
gave both the designer and contractor time
to address coordination problems prior to the
commitment of field resources.
CLAREMONT TUNNEL SEISMIC UPGRADE
A key to this water supply project was the design
and construction of the vault area. The vault
increases protection as the water supply crosses
the Hayward fault in the San Francisco Bay
area. All the major permanent and temporary
construction features were modeled for this
area for the purpose of design coordination,
constructability review, and sequencing. As
with the Milwaukee Harbor Siphons project, the
model’s primary function was to marry contract
design with contractor means and methods to
simulate the work months in advance of physical construction. The model streamlined the
construction process and reduced the risk of
changes and claims from the contractor.
Despite BIM’s association with the aboveground building market, the tools and approach
can be adopted for use underground. Each
market has unique characteristics that place
different demands on the technology. And yet in
both markets, the value comes from identifying
change when change is inexpensive to make. Or
perhaps better said, “Measure twice, cut once.”

than 10 years of experience with 3D modeling
and BIM.

Too Small to Prime?
It was about five years ago when one of our best
clients told me “Dan, we’d love to give you the
job, but Jacobs Associates doesn’t have deep
enough pockets.” At the time this was good
advice. It reflected our clients’ and our firm’s
general belief about what was needed to deliver
a large project. However, since that time we’ve
worked with firms that have deep pockets as
well as firms with no pockets, delivering some
pretty large projects. Time and again, when
challenges have come up, particularly unanticipated challenges, the ability to solve the
problem has been based on access to talented
staff, not access to a bank account. Because of
this we spend far more time focusing on adding to or training our staff than on financial
performance. Earlier this year, the same client
who told me five years back we’re too small
selected us to prime one of its more complex
projects, choosing Jacobs Associates over two
firms more than 10 and 20 times our size, as
measured by Wall Street. This win confirmed
our belief that while deep pockets are important in finance, depth of and access to talent are
what matters in engineering.

Expanding Underground at Lower Baker Dam
Sound Transit Heads North
Alternative Intake Project is Dedicated
The Waterview Connection in Auckland is a
landmark project for the New Zealand Transport Authority (NZTA) as it is the largest single
roading project ever undertaken in the country.
To maximize the efficient and economic use
of hydrologic resources for power generation,
Puget Sound Energy (PSE) is building an additional powerhouse at Lower Baker Dam to
help moderate the dam’s outflows and better
accommodate the needs of fish downstream.
The 285-foot-high (87-m) dam, built in 1927,
is located in northwest Washington State in
the Cascade Mountain Range and forms Lake
Shannon, a reservoir 7 miles (11.2 km) long.
Jacobs Associates has been selected by Sound
Transit to deliver civil engineering and architectural final design services for the North
Link light rail extension. North Link consists
of 4.3 miles (6.9 km) of double-track light rail,
which consists of 3.2 miles (5.2 km) of twin
bored soft-ground tunnels, 1.1 miles (1.7 km)
of retained cut fill, and elevated guideway
structures. It includes two underground transit
stations (Brooklyn and Roosevelt), one elevated
station (Northgate), a portal structure, and
20 cross passages.
Contra Costa Water District’s Alternative Intake
Project was formally dedicated on July 20, 2010,
at the Middle River Intake and Pump Station.
The facility was tested and brought online over
the summer, and has been operating as an integral part of CCWD’s system since late August.
Once constructed, the project, which includes
a large component of tunneling works, will
complete the Western Ring Route (WRR) and
will provide an alternative 48-kilometer (30mile) north-south motorway that does not rely
on the Southern Motorway or the Auckland
Harbour Bridge. The connection will improve
travel times and access between the west and
the south sides of the city and provide a motorway link from the Central Business District to
Auckland Airport.
Design and construction will be procured via
a competitive alliance. Because of the size and
complex nature of the project, the WRR has
been split into several packages, including
2.1-kilometer-long (1.3-mile) twin tunnels
(Avondale Heights Tunnel), a 450-meter-long
(1,476-ft) cut-and-cover tunnel, portal works,
and a motorway-to-motorway interchange
consisting of four viaducts totaling 1.8
kilometers (1.1 miles) in length. The Avondale Heights Tunnel will provide three
lanes of traffic in each direction.
Jacobs Associates has been engaged by
NZTA for the Avondale Heights Tunnel
and will provide technical expertise to
assist with developing the project’s
principal requirements. We will provide
technical guidance to short-listed tender
teams and will also assist with evaluation
of tender proposals.
The NZTA Board has approved up to NZ$2
billion to complete Auckland’s WRR, and
the project stands to create over 1,000
jobs in construction-related activities at
the peak of the project. Completing the
WRR, which is one of the New Zealand
government’s seven Roads of National
Significance Projects, will support and enable
economic growth for the country.
PSE is Washington State’s oldest and largest
energy utility, and serves more than one million
electric customers. Following a 1965 landslide
that significantly damaged some of the existing
facilities, PSE has investigated several ways
to return to maximum generation capacity. To
prevent similar problems and optimize land use
at the site, a new underground powerhouse and
connecting tunnel were selected as the best way
to achieve this.

Preliminary Design Complete for Caltrain Downtown Extension
Jacobs Associates recently completed preliminary design (30%) of the mined tunnel segment
for the Caltrain Downtown Extension (DTX).
The DTX is a 1.3-mile-long (2.1-km) rail extension being constructed by the Transbay Joint
Powers Authority (TJPA), which represents several transportation agencies in San Francisco
and the East Bay. This rail line will extend Caltrain rail service and the future California High
Speed Rail system to downtown San Francisco.
The downtown station will be the new Transbay
Transit Center (TTC), which will be constructed
on Mission Street at First Street. This is the site
of the former Transbay Terminal, which is in
the process of being demolished. The DTX tunnel will be constructed using a combination of
cut-and-cover and mined tunneling methods.
wide, depending on whether the alignment is
on a tangent or horizontal curve. Ground cover
above the tunnel crown will range from 30 to
65 feet (9 to 20 m). The tunnel is being designed
using the New Austrian Tunneling Method
(NATM) approach and will be one of the largest
NATM tunnels constructed in the U.S. when
completed. Current plans call for completing
final design in 2012 and construction by 2018.
The mined tunnel segment of the DTX is about
3,200 feet long (975 m) and runs from Third
and Townsend streets to Second and Folsom
streets. As the alignment transitions from
Townsend Street to Second Street, it passes
beneath 11 existing buildings. The tunnel’s
finished inside dimensions will be about 33
feet (10 m) high and 50 to 55 feet (15 to 17 m)

SH20 Waterview Connection
Expanding Underground at Lower Baker Dam
Sound Transit Heads North
Alternative Intake Project is Dedicated
The Waterview Connection in Auckland is a
landmark project for the New Zealand Transport Authority (NZTA) as it is the largest single
roading project ever undertaken in the country.
To maximize the efficient and economic use
of hydrologic resources for power generation,
Puget Sound Energy (PSE) is building an additional powerhouse at Lower Baker Dam to
help moderate the dam’s outflows and better
accommodate the needs of fish downstream.
The 285-foot-high (87-m) dam, built in 1927,
is located in northwest Washington State in
the Cascade Mountain Range and forms Lake
Shannon, a reservoir 7 miles (11.2 km) long.
Jacobs Associates has been selected by Sound
Transit to deliver civil engineering and architectural final design services for the North
Link light rail extension. North Link consists
of 4.3 miles (6.9 km) of double-track light rail,
which consists of 3.2 miles (5.2 km) of twin
bored soft-ground tunnels, 1.1 miles (1.7 km)
of retained cut fill, and elevated guideway
structures. It includes two underground transit
stations (Brooklyn and Roosevelt), one elevated
station (Northgate), a portal structure, and
20 cross passages.
Contra Costa Water District’s Alternative Intake
Project was formally dedicated on July 20, 2010,
at the Middle River Intake and Pump Station.
The facility was tested and brought online over
the summer, and has been operating as an integral part of CCWD’s system since late August.
Once constructed, the project, which includes
a large component of tunneling works, will
complete the Western Ring Route (WRR) and
will provide an alternative 48-kilometer (30mile) north-south motorway that does not rely
on the Southern Motorway or the Auckland
Harbour Bridge. The connection will improve
travel times and access between the west and
the south sides of the city and provide a motorway link from the Central Business District to
Auckland Airport.
Design and construction will be procured via
a competitive alliance. Because of the size and
complex nature of the project, the WRR has
been split into several packages, including
2.1-kilometer-long (1.3-mile) twin tunnels
(Avondale Heights Tunnel), a 450-meter-long
(1,476-ft) cut-and-cover tunnel, portal works,
and a motorway-to-motorway interchange
consisting of four viaducts totaling 1.8
kilometers (1.1 miles) in length. The Avondale Heights Tunnel will provide three
lanes of traffic in each direction.
Jacobs Associates has been engaged by
NZTA for the Avondale Heights Tunnel
and will provide technical expertise to
assist with developing the project’s
principal requirements. We will provide
technical guidance to short-listed tender
teams and will also assist with evaluation
of tender proposals.
The NZTA Board has approved up to NZ$2
billion to complete Auckland’s WRR, and
the project stands to create over 1,000
jobs in construction-related activities at
the peak of the project. Completing the
WRR, which is one of the New Zealand
government’s seven Roads of National
Significance Projects, will support and enable
economic growth for the country.
PSE is Washington State’s oldest and largest
energy utility, and serves more than one million
electric customers. Following a 1965 landslide
that significantly damaged some of the existing
facilities, PSE has investigated several ways
to return to maximum generation capacity. To
prevent similar problems and optimize land use
at the site, a new underground powerhouse and
connecting tunnel were selected as the best way
to achieve this.
Victor is a principal with more than 18 years
of experience and is providing consulting
services on the Waterview Connection project.

Preliminary Design Complete for Caltrain Downtown Extension
Jacobs Associates recently completed preliminary design (30%) of the mined tunnel segment
for the Caltrain Downtown Extension (DTX).
The DTX is a 1.3-mile-long (2.1-km) rail extension being constructed by the Transbay Joint
Powers Authority (TJPA), which represents several transportation agencies in San Francisco
and the East Bay. This rail line will extend Caltrain rail service and the future California High
Speed Rail system to downtown San Francisco.
The downtown station will be the new Transbay
Transit Center (TTC), which will be constructed
on Mission Street at First Street. This is the site
of the former Transbay Terminal, which is in
the process of being demolished. The DTX tunnel will be constructed using a combination of
cut-and-cover and mined tunneling methods.
wide, depending on whether the alignment is
on a tangent or horizontal curve. Ground cover
above the tunnel crown will range from 30 to
65 feet (9 to 20 m). The tunnel is being designed
using the New Austrian Tunneling Method
(NATM) approach and will be one of the largest
NATM tunnels constructed in the U.S. when
completed. Current plans call for completing
final design in 2012 and construction by 2018.
The mined tunnel segment of the DTX is about
3,200 feet long (975 m) and runs from Third
and Townsend streets to Second and Folsom
streets. As the alignment transitions from
Townsend Street to Second Street, it passes
beneath 11 existing buildings. The tunnel’s
finished inside dimensions will be about 33
feet (10 m) high and 50 to 55 feet (15 to 17 m)
Steve is a principal with more than 30 years
of experience and serves as the tunnel design
manager on the DTX project.

SH20 Waterview Connection
Expanding Underground at Lower Baker Dam
Sound Transit Heads North
Alternative Intake Project is Dedicated
The Waterview Connection in Auckland is a
landmark project for the New Zealand Transport Authority (NZTA) as it is the largest single
roading project ever undertaken in the country.
To maximize the efficient and economic use
of hydrologic resources for power generation,
Puget Sound Energy (PSE) is building an additional powerhouse at Lower Baker Dam to
help moderate the dam’s outflows and better
accommodate the needs of fish downstream.
The 285-foot-high (87-m) dam, built in 1927,
is located in northwest Washington State in
the Cascade Mountain Range and forms Lake
Shannon, a reservoir 7 miles (11.2 km) long.
Jacobs Associates has been selected by Sound
Transit to deliver civil engineering and architectural final design services for the North
Link light rail extension. North Link consists
of 4.3 miles (6.9 km) of double-track light rail,
which consists of 3.2 miles (5.2 km) of twin
bored soft-ground tunnels, 1.1 miles (1.7 km)
of retained cut fill, and elevated guideway
structures. It includes two underground transit
stations (Brooklyn and Roosevelt), one elevated
station (Northgate), a portal structure, and
20 cross passages.
Contra Costa Water District’s Alternative Intake
Project was formally dedicated on July 20, 2010,
at the Middle River Intake and Pump Station.
The facility was tested and brought online over
the summer, and has been operating as an integral part of CCWD’s system since late August.
Once constructed, the project, which includes
a large component of tunneling works, will
complete the Western Ring Route (WRR) and
will provide an alternative 48-kilometer (30mile) north-south motorway that does not rely
on the Southern Motorway or the Auckland
Harbour Bridge. The connection will improve
travel times and access between the west and
the south sides of the city and provide a motorway link from the Central Business District to
Auckland Airport.
Design and construction will be procured via
a competitive alliance. Because of the size and
complex nature of the project, the WRR has
been split into several packages, including
2.1-kilometer-long (1.3-mile) twin tunnels
(Avondale Heights Tunnel), a 450-meter-long
(1,476-ft) cut-and-cover tunnel, portal works,
and a motorway-to-motorway interchange
consisting of four viaducts totaling 1.8
kilometers (1.1 miles) in length. The Avondale Heights Tunnel will provide three
lanes of traffic in each direction.
Jacobs Associates has been engaged by
NZTA for the Avondale Heights Tunnel
and will provide technical expertise to
assist with developing the project’s
principal requirements. We will provide
technical guidance to short-listed tender
teams and will also assist with evaluation
of tender proposals.
The NZTA Board has approved up to NZ$2
billion to complete Auckland’s WRR, and
the project stands to create over 1,000
jobs in construction-related activities at
the peak of the project. Completing the
WRR, which is one of the New Zealand
government’s seven Roads of National
Significance Projects, will support and enable
economic growth for the country.
PSE is Washington State’s oldest and largest
energy utility, and serves more than one million
electric customers. Following a 1965 landslide
that significantly damaged some of the existing
facilities, PSE has investigated several ways
to return to maximum generation capacity. To
prevent similar problems and optimize land use
at the site, a new underground powerhouse and
connecting tunnel were selected as the best way
to achieve this.
Victor is a principal with more than 18 years
of experience and is providing consulting

Preliminary Design Complete for Caltrain Downtown Extension
Jacobs Associates recently completed preliminary design (30%) of the mined tunnel segment
for the Caltrain Downtown Extension (DTX).
The DTX is a 1.3-mile-long (2.1-km) rail extension being constructed by the Transbay Joint
Powers Authority (TJPA), which represents several transportation agencies in San Francisco
and the East Bay. This rail line will extend Caltrain rail service and the future California High
Speed Rail system to downtown San Francisco.
The downtown station will be the new Transbay
Transit Center (TTC), which will be constructed
on Mission Street at First Street. This is the site
of the former Transbay Terminal, which is in
the process of being demolished. The DTX tunnel will be constructed using a combination of
cut-and-cover and mined tunneling methods.

on a tangent or horizontal curve. Ground cover
above the tunnel crown will range from 30 to
65 feet (9 to 20 m). The tunnel is being designed
using the New Austrian Tunneling Method
(NATM) approach and will be one of the largest
NATM tunnels constructed in the U.S. when
completed. Current plans call for completing
final design in 2012 and construction by 2018.
The mined tunnel segment of the DTX is about
3,200 feet long (975 m) and runs from Third
and Townsend streets to Second and Folsom
streets. As the alignment transitions from
Townsend Street to Second Street, it passes
beneath 11 existing buildings. The tunnel’s
finished inside dimensions will be about 33
feet (10 m) high and 50 to 55 feet (15 to 17 m)
Steve is a principal with more than 30 years
of experience and serves as the tunnel design
manager on the DTX project.

JUST ANSWERS by Eric Westergren
Part II of BIM Series
BIM CAN MAKE A DIFFERENCE
UNDERGROUND
Building Information Modeling (BIM) has
traditionally been the domain of the general
building market because of its early adoption
by owners like the U.S. Government General
Services Administration. Because of BIM’s success, however, owners in other markets are now
starting to request it on their projects, including
those in the underground construction market.
BIM underground has some unique advantages over BIM for buildings. In general, heavy
civil projects have larger economies of scale,
meaning small tweaks to design and approach
early in the process have a greater influence
on a project’s overall cost. This, coupled with
the larger margins associated with the risk to
perform the work, makes the underground
market fertile soil for the predictive characteristics inherent in BIM.
Prior to joining Jacobs Associates I had the
opportunity to implement BIM on a variety of
underground projects as a consultant. Here is
a brief description of two projects where BIM
added value to the design coordination and
construction process:
MILWAUKEE HARBOR SIPHONS
Three-dimensional models were created to
coordinate the layout and fabrication of largediameter piping, both on the surface and underground. Underground the model was also
used to verify survey control and excavated
limits to ensure proper clearances were maintained. On the surface, the model was used to
verify pipe routing and check for interferences
Section through vault area showing
primary support and transitions.

and underground piping shown.

with other structures, including shaft support
of excavation, pipe cradles, thrust blocks,
valve chambers, and pile locations. During
this process multiple pile locations were found
to be in conflict with pipe routes and were
caught before pile driving began. Excavation,
concrete, and backfill quantities were also derived from the model once the final layout was
determined. The value came from assembling
all the components early in the process, which
gave both the designer and contractor time
to address coordination problems prior to the
commitment of field resources.
CLAREMONT TUNNEL SEISMIC UPGRADE
A key to this water supply project was the design
and construction of the vault area. The vault
increases protection as the water supply crosses
the Hayward fault in the San Francisco Bay
area. All the major permanent and temporary
construction features were modeled for this
area for the purpose of design coordination,
constructability review, and sequencing. As
with the Milwaukee Harbor Siphons project, the
model’s primary function was to marry contract
design with contractor means and methods to
simulate the work months in advance of physical construction. The model streamlined the
construction process and reduced the risk of
changes and claims from the contractor.
Despite BIM’s association with the aboveground building market, the tools and approach
can be adopted for use underground. Each
market has unique characteristics that place
different demands on the technology. And yet in
both markets, the value comes from identifying
change when change is inexpensive to make. Or
perhaps better said, “Measure twice, cut once.”
Eric is a project engineer and has more
than 10 years of experience with 3D modeling
and BIM.

Mission Trails Pipeline Tunnel & Vent Demolition Project Completed
Too Small to Prime?
It was about five years ago when one of our best
clients told me “Dan, we’d love to give you the
job, but Jacobs Associates doesn’t have deep
enough pockets.” At the time this was good
advice. It reflected our clients’ and our firm’s
general belief about what was needed to deliver
a large project. However, since that time we’ve
worked with firms that have deep pockets as
well as firms with no pockets, delivering some
pretty large projects. Time and again, when
challenges have come up, particularly unanticipated challenges, the ability to solve the
problem has been based on access to talented
staff, not access to a bank account. Because of
this we spend far more time focusing on adding to or training our staff than on financial
performance. Earlier this year, the same client
who told me five years back we’re too small
selected us to prime one of its more complex
projects, choosing Jacobs Associates over two
firms more than 10 and 20 times our size, as
measured by Wall Street. This win confirmed
our belief that while deep pockets are important in finance, depth of and access to talent are
what matters in engineering.

After 27 months of design, a 12 month hiatus,
and 24 months of construction, the San Diego
County Water Authority’s Mission Trails Pipeline
Tunnel and Vent Demolition (MTPT) project is
essentially complete, with the final walk-through
conducted at the end of September. Eventually,
the project will deliver water from the existing
Second San Diego Aqueduct to a future flow
regulatory structure and back into the Second
Aqueduct, thereby protecting the existing aqueduct from potential hydraulic surges.
Located in the Mission Trails Regional Park,
one of America’s largest urban parks, the $28
million MTPT project required construction of
a 92-inch-diameter (2,340-mm) welded steel
pipeline. This involved developing two portals;
two 10-foot-wide (3-m) horseshoe tunnels totaling 4,500 feet (1,372 m); two shafts up to 150
feet (46 m) deep; upstream and downstream
connections to the existing Second Aqueduct;
and demolition of existing pipeline and vent
structures between the shunt connections.

Underground access to the mine is currently provided by two vertical shafts. The
proposed liquid argon cavern, including
permanent operational access, would be
isolated from the existing mine workings
to allow any accidental escape of argon gas to
be ventilated outside and not into the existing
facility. The cavern would be accessed through
two new portals at ground surface. These portals provide two independent means of access
to the cavern and will also provide ventilation.
A third egress point will be through a new
drift connected to the existing 800-foot-level
(244-m) mine workings. This drift will be for
emergency escape.
