Paper Title |
Authors/Organization |
Description |
| 8:00 AM |
Interceptor
Assessment - Taking the First Look |
Glenn Jones and Mike Stram, City of
Reno |
This paper identifies how the City developed it
condition assessment programs and how the large quantities of
data was collected, compiled and analyzed. Based on our
experience the primary issues will include field data to collect,
QA/QC on data, tracking field data with GIS, assessment criteria,
and program implementation. |
| 8:25 AM |
Milwaukee MSD I/I Reduction Cost-Effectiveness |
Julie McMullin and Andy Lukas, Brown
and Caldwell, and Steve Heinz, Milwaukee Metropolitan Sewerage
District |
This paper looks at the cost-effectiveness of infiltration
and inflow (I/I) rehabilitation using trenchless technology methods,
as seen from the Milwaukee Metropolitan Sewerage District’s recent
I/I Reduction Demonstration Project. |
| 8:50 AM |
Sewer
Rehabilitation: Integral Component of an Infrastructure Rehabilitation
Program in Fort Lauderdale, Florida – Part II (Implementation
and Results) |
Walt Schwarz, P.E., CH2MHill |
This paper discusses development of specific projects,
experiences with projects constructed to date and implications
of flow data obtained following completion of the two Ft Lauderdale
projects. Standard project specifications were developed
to encourage competition and reduce the effort required to get
projects out to bid. Construction costs have been extremely competitive,
with 3-4 bidders submitting for each project. |
| 9:15 AM |
Lesson Learned in Grout Cleaning of Underground
Sewers Using Trenchless Technologies |
Albert Kwan, and Ken Chua, City of Edmonton |
The paper describes lessons learned on several trenchless
methods in cleaning a blocked sewer. |
| 9:40 AM |
Inspection and Evaluation of Pipe Lining Materials |
Eugenia Chusid, City of Santa Monica |
This paper will describe experiences with using
multiple lining methods and materials, 5 – 6 years post installation
condition investigation, methods of investigation and its findings. |
| Track 2 |
Underground
Damage Prevention - Team Leader: Myron Shenkiryk, Moderator:
Brian Tooley |
| Time |
Paper Title |
Authors |
Description |
| 8:00 AM |
Using
the D.I.R.T. Tool for Effective Analysis of Damages |
Brian Tooley, Verizon Business Services
and Arch York, Sprint |
This presentation describes the Damage Information
Reporting Tool (DIRT) developed by the Common Ground Alliance
(CGA) to collect damage information. The primary purpose
in collecting underground facility damage data is to analyze data,
to learn why events occur, and how actions by industry can prevent
them in the future; thereby, ensuring the safety and protection
of people and the infrastructure. |
| 8:25 AM |
Arrayed Signal Processing for Collection
and Depiction of Existing Subsurface Utility Data |
Andrew Lund, Witten Technologies, Inc. |
This paper describes 2 new “arrayed-antennae-based”
utility detection technologies, both of which avoid damage during
construction by providing accurate information (in x, y, and z)
about existing underground infrastructure during design. |
| 8:50 AM |
Utilization of ASCE Standard 38-02
and Subsurface Utility
Engineering
Principals |
Lawrence Arcand, TSH/TBE Subsurface
Utility Engineers JV |
This paper outlines the increased use of Subsurface
Utility Engineering Principals in Ontario. The paper highlights
projects that have been completed and the benefits that have been
obtained. |
| 9:15 AM |
Sewer Laterals and Gas Lines
Make Time Bombs |
Walt Kelly, Walt Kelly Enterprises,
Inc. |
This paper presents a legislative solution to reduce
the incidence of cross-bores of sewer laterals. The papers identifies
states that have taken legislative action to address this issue. |
| 9:40 AM |
Obstacle
Detection Sensor and Tow Tension Monitor for HDD |
Max Kieba, Gas Technology Institute,
and Erez Allouche, Trenchless Technology Center |
This paper describes two technologies being developed
to help prevent damage during HDD installations; an obstacle detection
sensor to detect utilities during pre-bore and a wireless weak-link
that measures the tensile load during pullback. |
| Track 3 |
Microtunneling:
Construction Issues, Team Leader: Glenn Boyce, Moderator:
Bob Ericsson |
| Time |
Paper Title |
Authors |
Description |
| 8:00 AM |
Microtunneling
and HDD Through Alluvium in Chula Vista, CA. |
Craig Camp, Jacobs Associates |
This paper describes HDD and microtunneling design
and construction the same soil conditions. |
| 8:25 AM |
Design & Construction
Issues with SRCSD Tunnel Shafts |
Andrew J. Finney and Steven W. DeCou,
CH2MHill; and, Lysa Voight, Sacramento Regional County Sanitation
District |
This paper presents shaft construction case histories
including: the relative merits of secant-piles and sunken concrete
caissons in hard ground; stabilization of saturated soils during
launch; and potential rebound and settlement of shaft foundation
soils. |
| 8:50 AM |
Post-Construction Evaluation of Trenchless Construction |
Mike Jaeger, PE, Covellow Group; Ray
Post, Michels Pipeline; and Dan Breg, and Mike Cole, EPC Consultants |
This paper describes and evaluates the design and
value engineering changes for microtunneling and directional drilling
on the LNWI project in West Sacramento, California. |
| 9:15 AM |
Comparison of Risk Management Strategies for
Microtunneling |
Ulf G. Gwildis, and Michael B. Gilbert,
Camp Dresser and McKee |
The paper compares two microtunneling projects where
the risk management strategy focus varied depending on the relative
importance of risks associated with successful completion of the
tunnel and those associated with minimizing environmental impacts. |
| 9:40 AM |
Challenging
Geotech and Differing Site Conditions Microtunneling SeattleÕs
Green River Requires Two Different Head Configurations |
Kim Staheli, PhD., P.E., Bennett/Staheli
Engineers |
This paper presents the challenging aspects of crossing
beneath the Green River with microtunneling through wood, cobbles,
and boulders. The Contractor filed a DSC claim prior to
tunnel construction, requiring a unique contracting arrangement
for the microtunnel construction. This paper presents the
lessons learned from tunneling and contract management. |
