Stat-X fire suppression systems protect Eurostar trains
Eurostar
trains in Europe were designed with channel tunnel safety in mind and consist of two
independent half-sets, each with its own power car. In line with Eurostar policy,
continuous research is carried out to establish the best means of
protecting both rolling stock and passengers while at the same time complying
with all current safety and environmental issues. This includes the Kyoto
Protocol, which forbids the use of Halon as a fire suppression agent.
On behalf
of Eurostar, and responding to the Kyoto requirement for legally binding
commitments for the reduction of greenhouse gases, Brush Traction engineers researched available fire-extinguishing systems such
as water mist, FM200, Novec 1230, inert gases and condensed aerosol systems as
possible alternatives to the current Halon system installed. Their research concluded that the technical leader was Stat-X.
Stat-X fire suppression systems are distributed
throughout Europe by Nobel Fire Systems, a trained and certified Stat-X
distributor. Over the last two years
Brush, Eurostar, and Nobel have been working together to prove the
effectiveness of the system to the Channel Tunnel Safety Authority (CTSA) and
the Channel Tunnel Intergovernmental
Commission (ICG), including a series of full-scale mockup fire tests at the
French fire systems approvals and testing authority CNPP based in Vernon
France. On successful conclusion and with
final signoff from both the CTSA and the ICG, Eurostar awarded Nobel the
contract in July 2012, due for completion in 2015. Nobel has started the removal of
the Halon and installation of Stat-X systems, and work on the first two of the 28 trains is now
complete.
The Stat-X system, which also includes a
custom interface control panel, is designed to protect the power car, including
transformer, common block, and motor block, using both localized and total flood
protection methods. In the event of an
onboard fire, Stat-X generators can be activated either manually or
automatically via the integrated dash-mounted control panel. On activation, the
generators produce an ultra fine, potassium-based
aerosol.
Unlike gaseous systems, Stat-X aerosol
generators are cost-effective to install and maintain as they do not require
the pressure vessels, piping, or expensive installation costs associated with
other extinguishing systems. Space and weight requirements are minimal and, in
many applications, the compact size of the Stat-X aerosol generators makes them
the only viable option. Stat-X aerosol
generators are virtually maintenance free and have a shelf life of over ten years.
Stat-X fixed systems and
Stat-X First Responders are automatic condensed aerosol fire suppression solutions that are eco-friendly (zero ozone depletion, zero atmospheric life, and insignificant
global warming potential) and non-toxic. They save lives and protect property for facilities,
machinery, vehicles, and industrial sites such as surface and underground mines,
military vehicles, long-haul buses, rolling stock, remote telecom sites, wind
turbines, power substations, electrical cabinets, and various marine and
off-shore settings. They can be manually, thermally, or electrically activated by industry-standard control
panels. Stat-X is manufactured by Fireaway, a company with production facilities in Minnetonka, Minnesota
and Minden, Louisiana. Visit www.statx.com for further information.

Engineering students help design award-winning WPI Sports and Recreation Center
Worcester Polytechnic Institute’s (WPI) new Sports and Recreation Center has garnered accolades, with its natatorium structural design acknowledged with an award by the Precast Concrete Institute (PCI) and the U.S. Green Building Certification Institute awarding LEED (Leadership in Energy & Environmental Design) Gold certification.
PCI named the Sports and Recreation Center its 2013 Best Higher Education Building award winner. The 145,000-square-foot Sports and Recreation Center opened last year. In addition to providing WPI students, faculty, and staff with state-of-the art sports and fitness facilities, the center provides the university space for hosting regional and national robotics competitions as well as other non-sporting events such as admissions open houses, career fairs, and national academic conferences.
Development of the new center was part of WPI's seven-year capital plan. In February 2007 the WPI Board of Trustees adopted a policy calling for all future buildings on campus to be environmentally friendly and designed to meet the U.S. Green Building Council’s LEED certification. The center is WPI’s third LEED-certified building, after the Bartlett Center—home to the Admissions Office and the first LEED-certified building in Worcester—and East Hall, a residence hall built in 2008 that boasts Worcester’s first living green roof and that received LEED Gold certification.
Sustainability is a major focus for the university. Faculty members have incorporated sustainability into many student projects and focused on various aspects of sustainability around the world. In the year 2012 alone, some 51 energy-related projects were completed at WPI. Topics of these projects range from those with a social focus to highly technical investigations. Other recent highlights include the Solar Decathlon China 2013 and the Electric Power Industry Symposium.
During the construction of this the center, WPI also capitalized on the opportunity to provide teaching and learning opportunities for engineering faculty and students. Civil and mechanical engineering students worked with the architects Cannon Design of Boston and the construction managers, Gilbane Building Co. of Providence, to enhance 3D building information modeling (BIM) software, creating a system that integrates all design and construction data. The enhanced system enabled the designers and builders to make changes in HVAC plans and increase the height in the new robotics area, greatly improving its effectiveness and value.
A major feature of the Sports and Recreation Center is the precast concrete natatorium structure housing a 25-meter competition swimming pool with spectator seating. The structure features five-piece precast concrete components spanning 110 feet across the pool. The five pieces include two column pieces, two corner pieces, and one center beam piece. Precast concrete double-tees span between the bents and support the four-court gymnasium above. The steel-frame structure of the third-floor gymnasium is supported on the precast concrete natatorium structure. The natatorium structure is also integrated into other surrounding steel structures.

Plastic Pipes Conference call for papers
An official call for
papers has been announced for Plastic Pipes XVII. This international Plastic
Pipes Conference and exhibition will be hosted in Chicago 22 – 24 September
2014. Organizers have requested authors to submit paper abstracts
in English before 15 November 2013 with final deadline for completed work to be
posted by 16 May 2014.
Whereas key subject areas
will be market issues, pipeline solutions, application areas, material testing, and performance, special consideration will be given to relevant contributions
outside of these criteria. At least 100 individual presentations are scheduled
for this event that continues to provide a major technical and commercial
window and platform for the industry.
Stephen Boros, VP of engineering at Pipeline Plastics and chairman of the PPXVII conference, explains
that Chicago will be one of the most important events for our industry to share
new developments in the field of plastic pipe technology and use. “Low cost,
ease of installation, sustainability, and long-term performance advantages of
plastic pipes continue to propel the industry towards greater global demand in
all application sectors. Worldwide expectations for a six-percent annual growth
in their use over the next few years are now viewed as conservative given the overwhelming
trend for replacement of antiquated competing pipe materials. Increasing demand
in energy sectors such as oil and gas gathering and gas distribution, as well
as replacement of older failing water and sewer systems is driving much of this
growth. This demand is also promoting
further development of plastic-based composite piping systems for very high
pressures, and new materials such as high performance polyethylene compounds
and manufacturing techniques such as bi-oriented PVC technology.”
Conference audiences are
typically drawn from a wide spectrum of industry stakeholders that include pipe
and fitting manufacturers; gas, water, and sewer utility providers; raw material
and additive suppliers; pipeline design engineers; pipeline installers; technical
institutes; and industry associations from all over the world. Plastics Pipes XVII is
organized in collaboration with The Plastics Pipe Institute, TEPPFA, PE100+ Association and PVC4Pipes.
Paper topics, how to
submit an abstract, conference registration, and other information is available from Eva Balassa at eva@congress.hu or by visiting www.ppxvii.org.

FIU to develop technology to fix and build bridges
The U.S. Department of Transportation has awarded Florida International University (FIU) a $1.4 million grant to work on one of the nation’s leading challenges: deteriorating bridges. The Accelerated Bridge Construction University Transportation Center (ABC-UTC) at FIU is the first federally funded entity focused on developing technology and methods to improve and accelerate the construction of bridges. The center, led by bridge engineer Atorod Azizinamini, will tackle an urgent transportation need; most of the nation’s roadway system was designed more than 50 years ago to carry much less traffic. Approximately 25 percent of U.S. bridges are structurally deficient or functionally obsolete and need to be retrofitted or replaced, according to the American Society of Civil Engineers.
The grant, by the DOT’s Research and Innovative Technology Administration, makes FIU one of 20 Tier One University Transportation Centers in the U.S. Funding is eligible to be renewed in 2014. Matching funds could bring the total impact of the project to more than $5.6 million over two years. Earlier this month, FIU won an $11.4 million TIGER grant from DOT to improve connectivity between the university’s west Miami-Dade campus, the neighboring city of Sweetwater and other parts of Greater Miami. The public-private UniversityCity project will include a pedestrian bridge over Southwest Eighth Street and a transportation hub at FIU.
Azizinamini, also chair of FIU's Department of Civil and Environmental Engineering, says the center will focus on faster construction methods that are more cost-effective and result in more durable bridges while minimizing interruptions to traffic. “Our objective is to make accelerated bridge construction the new way of building bridges. To do that, we have to develop new technology, we have to transfer that technology to the profession, and we have to develop the workforce.” Azizinamini is also the principal investigator on another multi-million dollar national project that resulted in the development of the first comprehensive document dedicated to enhance the service life of bridges titled Design Guide for Bridges For Service Life.
The ABC-UTC, which includes researchers from Iowa State University and the University of Nevada, Reno, will hold its first steering committee meeting in December. FIU is also home to the Lehman Center for Transportation Research, which has served South Florida and the nation for 20 years in transportation.

McLaughlin Water Engineers selected for infrastructure development at New Mexico ski area
McLaughlin Water Engineers (MWE), a division of Merrick & Company, was selected as the engineer to provide master planning, design, construction management, and development reviews for the high-mountain village of Taos Ski Valley, NM. The village is home to a large ski resort in the mountains of northern New Mexico with an elevation above 10,000 feet. With an annual average snowfall of over 300 inches, the snow creates optimal conditions for winter sports but presents challenges in providing the necessary infrastructure to support the population, specifically at the height of the ski season.
The original water infrastructure of the village had utilities that leaked, occasionally froze, and required constant maintenance. Given these conditions, the village was recently awarded a $2 million financing program to upgrade its water system from the New Mexico Water Trust Fund. Program elements include a 250,000 gallon underground tank beneath a ski run to protect the base village, seven replacement pressure control stations, approximately 5,000 feet of key pipelines, and a water disinfection/control station. This program is to be completed by the 2013/2014 ski season.
An employee-owned firm, Merrick & Company (www.merrick.com) provides comprehensive civil engineering and surveying services to private and public sector clients. Merrick focuses on civil infrastructure for public works, municipal, district, federal, and private development clients, including services for street and roadway design, drainage engineering, water resources and systems, wastewater systems, land development, and federal base infrastructure.
