Dr. Raymond Henn and
Nathan Soule recently celebrated the publication of their new
book entitled "Ultrafine Cement in Pressure Grouting".
The 94-page book was published by the American Society of Engineers.
Tracy Lyman attended
the North American Society for Trenchless Technology in Chicago,
IL from May 2 through 5, 2010. He presented a paper entitled
"Tunneling in Variable Rock Conditions: Flexibility is
Key". Please contact Lyman Henn for a copy of the
paper or presentation slides.
Tracy Lyman provided
a lecture at the Microtunneling Shortcourse held at the Colorado
School of Mines in February 2010. The lecture was on Microtunnel
Project Design.
Tracy Lyman is serving
as Chair of Qualifications Based Selection (QBS) Committee in
Colorado. Mr. Lyman serves on the committee as a representative
of the American Consulting Engineers Council (ACEC). The
committee has 10 members, who serve as a Board of Directors.
The Directors represent ACEC, AIA, CAGE, PEC in Colorado.
The committee strives to promote the use of QBS for selection
of engineers and architects by informing and educating owners
of built facilities of the advantages of QBS. For a summary
of a recent study detailing the advantages of QBS on the life
cycle cost of construction projects, please contact Lyman Henn.
Lyman Henn provides
engineering services for ASCE Outstanding Civil Engineering
Project Award for 2009. ASCE's newsflash on this prestigious
award follows. 
For its creative, effective solution to water
shortage challenges, the Orange County , Calif. , Groundwater
Replenishment System has been selected as ASCE's Outstanding Civil
Engineering Achievement for 2009. With water demand soaring in
southern California , Orange County needed a solution that was
more cost-effective than importing water or desalination and would
satisfy needs for decades to come. The county's Water and Sanitation
District opted for a process that recycles and purifies wastewater
and returns it to reservoirs and groundwater aquifers – one which
also mitigates the impact of droughts. ASCE President Wayne Klotz
calls the system “an excellent example of how civil engineering
can contribute to a community's economic success, improved residents'
quality of life and protect public safety.” The award was announced
and presented to Orange County water officials at the Society's
OPAL Gala Thursday evening.
Lyman Henn, working as a subconsultant to CDM,
provided trenchless pipeline design services for final design
of the 27 trenchless crossing required for the project. The crossings
included several highways, railroads, canals and utility corridors.
