Arrowhead Tunnels of the Inland Feeder Program -San Bernardino, California

The Metropolitan Water District (MWD) of Southern California's Inland Feeder consists of three separate tunnels , together totaling 18miles .The Arrowhead Tunnels project , which consistsof two 19-foot excavated-diameter tunnels , is akey segment of the MWD of Southern California's44-mile-long Inland Feeder , created to deliverabout 646 million gallons of emergency water aday to mil lions of residents , MWD employeemagazine People.Interactive explains.

"Tunnel excavation was challenging, with highlyvariable ground conditions. The tunnel alignments cross

active splays of the San Andreas fault in threelocations , encountering sheared rock and raveling andsqueezing ground ," tunnel engineering firm JacobsAssociates says of the Arrowhead Tunnels project.

The project required the use of probe holes to assessground conditions ahead of huge tunnel-boringmachines (TBM), which, combined with the use of straingauges to monitor tunnel pressure, were able to digfaster and with fewer stops and starts.

Following excavation, precast concreteliners, mortar and steel pipes were installed.

According to Jacobs Associates, which playednumerous roles in the project's planning andexecution, "the design incorporates severalunique features."

Ultimately, the tunnel's lining design is

expected to allow it to withstand a magnitude8.0 earthquake.

Central Link's Section 710 - Seattle,Washington

For Sound Transit Central Link's Light Rail, The challenge of Section 710 lay in

building a deep-mined transit station andone mile of twin rapid transit tunnels underBeacon Hill

as part of the region's new light rail systemextending from downtown Seattle to SeaTacAirport.

Advantage

"The tunnel needed to be deep to avoiddisrupting businesses and traffic on thesurface, plus it would involve construction inextremely unstable soils, including stratifiedsilt, sand and clay," according to the AmericanCouncil of Engineering Companies of

Washington (ACEC Washington).

Sequential Excavation Method

The engineering design team used theSequential Excavation Method (SEM)The practice of digging a tunnel in sections,

supporting each segment as you go tocarefully manage the multiple soil challenges."This approach to deep, complex tunneling invery poor soils, at a depth and a diameter closeto twice that previously done, resulted in thelargest soft ground SEM tunnel in NorthAmerica," the ACEC Washington says.


13/30

Earth pressure balance tunnel-boringmachine (EPB-TBM)

This project also required new drilling techniques,including the use of an earth pressure balancetunnel-boring machine (EPB-TBM).

Running tunnels were lined with a single pass,pre-cast concrete liner fitted with gaskets toensure water tightness. Despite the poor soils,

the tunnels were completed with virtually noground settlement or aboveground disruption

Lakeshore EnvironmentalEnhancement and Education Project -

Mequon, Wisconsin Bordering a steep, precarious bluff above thewater

Concordia University Wisconsin's (CUW) campuswas essentially cut off from direct lakefrontaccess .

Extensive erosion of the bluff itself compoundedthis problem.

Bluff = A steep headland, promontory, riverbank,

or cliff.


15/30

Promontary A promontory is a prominent

mass of land that overlookslower lying land or a body of

water (where it may be calleda peninsula or headland ).

Most promontories are either formed from a hard ridge of

rock that has resistedthe erosive forces that haveremoved the softer rock to the

sides of it, or are the highground that remains betweentwo river valleys where they

form a confluence .Throughout historymany forts and castles havebeen built on promontoriesbecause of their inherent

defensibility. The promontory

forts in Ireland are examplesof this.

"The stabilization effort involved removing material fromthe University's steep 2,700-foot long Lake Michiganbluff , stabilizing and seeding the entire site with nativespecies, and constructing major shoreline revetmentand breakwater structures , as well as managing a 34-acre fill site ," the Wisconsin chapter of the AmericanSociety of Landscape Architects (WIASLA) explains.

Interdisciplinary requirements

Bioengineering and aquatic biology were fusedwith landscape architectural practices to "meetthe project's challenging technical requirementsand provide effective interdisciplinary solutionsproviding stabilization, restoration and publicaccess," the WIASLA says.

State Capitol Seismic Base Isolation -Salt Lake City, Utah

When the Utah State Capitol building, locatedseveral hundred feet from an active fault capableof a magnitude 7.3 earthquake, failed seismic

evaluations, state authorities embarked on abase-isolation retrofit to protect the massive andornate building.

Popular Mechanics explains that the foundations

had to be "pulled out without raising or loweringthe 132-million-pound building by more than1/16th of an inch."

20/30

Load transfer scheme According to VSL, a designer and manufacturer

involved with the project, "the designersdeveloped a method of permanently re-

supporting the rotunda of the capitol with aunique circumferential post-tensioned concreteload transfer scheme that necessitated the needfor temporary support of the existing footings,

eliminated the risk of settlement, minimized theneed for demolition and avoided cutting ordamaging the existing footing reinforcement."

Seismic Isolators

Ultimately, contractors strengthened thecapitol using 256 state-of-the-art seismicisolators beneath the building , whilereinforcing the dome and other structuralelements.

Sutong Bridge in Nantong City -Jiangsu Province, China

The Sutong Bridge, The only non-U.S. finalist contending for

ASCE's latest annual OCEA award, lies

between Nantong and Changshu in the east of China's Jiangsu province.

Spanning the Yangtze River, the all-China

project is designed to cut travel times fromShanghai to Nantong from four hours (byferry) to one hour via six-lane expressway.


23/30

longest span cable-stayed bridge

The Sutong Bridge has a span of 1,088 meters(3,570 ft.), setting a world record for thelongest span cable-stayed bridge .

It is also the world's first with a main span thatexceeds 1,000 meters.

The previous record holder, Japan's TataraBridge, has a main span of 890 meters.


24/30

Worlds highest bridge tower

The bridge is supported by soaring steel andconcrete towers that stand over 300 meterstall, making it the world's highest bridgetower, according to World Records Academy .Upon completion, the bridge set other worldrecords: the deepest foundation of any cable-

stayed bridge ( 120 meters ) and the longeststayed cable (577 meters).
