Green Building
America’s buildings and residences use 1/3 of its energy and
two-thirds of its electricity. They emit 49% of sulfur dioxide emissions,
25% of nitrous oxide, 10% of particulates, and 35% of carbon dioxide. They
consume masses of natural materials and are 40% of landfill . Unhealthy
indoor air costs 150 million workdays and $15 billion of productivity
annually.
The Green Building movement has become mainstream in
building design and construction. The architect most closely associated
with spearheading the movement is William McDonough, AIA. In 2000,
the U.S. Green Building Council adopted the Leadership in Energy and
Environmental Design (LEED) Certification System of industry benchmarks
and standards that define an environmentally responsible building. Over US
50 projects are LEED certified.
The Chesapeake Bay Foundation's Philip Merrill
Environmental Center, in Annapolis, Maryland, received the first LEED
Platinum Certification. The Foundation spent an extra $1.5 million to make
its $6.3 million headquarters green but will save energy and and water
over its life. It uses 2/3 the energy of a comparably sized office
building. Features include composting toilets, recycled materials,
photovoltaic cells, geothermal heating and cooling, and rainwater
collection. The Center uses less than 100 gallons of water per day and
releases 60 gallons of wastewater. The site uses natural flora and
is low maintenance.

Control System on Chip
A device smaller than a paper clip has revolutionized the
control of all building systems, using a single control network. Echelon
Corporation created a paradigm shift in traditional control system design
and installation with LonWorks, a control network technology platform that
is an open, non-proprietary technology that any vendor may incorporate in
its products. Traditional control systems require multiple trades,
multiple network cabling and conduit systems, and ultimately require that
control software for multiple systems be laboriously programmed to “talk
together” in order to function properly.
The neuron chip is non-proprietary and enables
equipment from different manufacturers to communicate with each other. The
control chip is used to create building automation systems where a single
device control network monitors and controls all building functions,
including lighting, HVAC, security access, backup generators, elevators,
and power management. LonWorks guarantees the interoperability of
thousands of manufacturers’ products across almost every vertical
industry.
The control chip has benefited manufacturers and end
users by creating an open market, simplifying control systems, design,
construction, and installation; and reducing initial, running, and
management costs. LonWorks has countless successful application in
commercial buildings, industrial settings, transportation systems, homes,
and utilities.

Close Range Photogrammetry
Photogrammetry, measuring objects from photographs, has been
used since the late 1800s, most commonly for mapping large areas from
aerial photographs. A recent, innovative development digital Close-Range
Photogrammetry (CRP) accurately measures objects directly from photographs
or digital images captured with a camera at close range. Accurate as-built
3D models of facilities and plant equipment are produced from multiple
overlapping images taken from different perspectives.
BE&K As-Built Services created CRP software and
processes it has widely used in its consulting services. Vexcel developed
and markets FotoG CRP software that is broadly used for exacting
measurements. EOS Systems developed and widely markets PhotoModeler, less
expensive CRP software and hardware for a variety of uses. The James W.
Sewall Company of Old Town, Maine, nominated close range photogrammetry
for the NOVA Award after using it for a dimensional inspection survey of
the Waldo-Hancock Bridge across the Penobscot River in Maine.

NOVA AWARD WINNER
Automatic Rebar Tying Machine
Tying steel reinforcing bars has always been tough, manual labor,
as reinforcing ironworkers spend much of the day hunched over tying rebar.
To address this issue, in 1994 the Bentac Company of Japan introduced the
U-Tier automatic rebar tying machine. This was the first fully automatic
machine to tie rebar. The Japan Automatic Machine Company purchased the
rights to U-Tier and introduced the design refinements and improvements
now in broad use. In an independent, but parallel effort, the MAX Company
of Japan introduced the automatic Re-Bar-Tier.
Both machines are uniquely designed to replace the
manual and backbreaking process of tying rebar. The machines hold the
crossed reinforcing bars, feed the tie wire, then wind, cut, and tie in
one action. The result is a strong, single strand, double wrap tie. The
automatic rebar tying machine can be used in numerous applications
including highways, roads, and bridges; concrete slabs precast/prestressed
concrete; electrical vaults; foundations; cages; and manholes.
Advantages of the rebar tying machine include saving
time through productivity improvements, reduction of on-the-job injuries,
consistent results, and reduction of material costs by decreasing wire
consumption.

NOVA AWARD WINNER Prestressed Carbon
Fiber Reinforced Plastic
Steel reinforcement used in concrete bridge decks and beams
corrodes when exposed to de-icing chemicals and is a major cause for
bridge repair and replacement. The premature failure of reinforced
concrete components on the Bridge Street Bridge prompted the City of
Southfield, Michigan to try something different.
A task force of city, state, and federal officials,
including engineer Hubbell, Roth & Clark, CFRP Material Manufacturers, and
representatives from Lawrence Technological University, and the University
of Windsor was created to develop the concept. Two concrete bridges were
built in parallel. One used conventional steel reinforcing, and the other
was solely reinforced with carbon fiber reinforced polymers (CFRP),
including internal pre-tensioned tendons and external post-tensioned
cables.
CFRP is composed of long fibers woven together and
encased in epoxy. Its light weight, high tensile strength, and corrosion
resistance can increase the potential service life of bridges, which
reduces safety hazards and maintenance costs. This is the only bridge of
this type in the world.

Pavement Quality Indicator
TransTech Systems’ Pavement Quality Indicato (PQI) makes
instantaneous, in-situ measurement of field pavement density. This
contrasts with the traditional destructive and time consuming methods of
measuring asphalt pavement density and the strict licensing requirements
associated with the use of the nuclear densitometer. PQI was developed by
TransTech Systems in 1995 under the New York State Energy Research and
Development Authority Agreement.
The PQI makes innovative use of a constant voltage, low
frequency, electrical impedance approach that measures compaction level or
density by measuring the change of the electrical impedance of the
material matrix through the use of a flat sensing plate.
The density of asphalt pavement is
directly proportional to the measured dielectric constant of the material.
The PQI uses electrical waves to measure the dielectric constant using an
innovative, toroidal electrical sensing field established by the sensing
plate. The electronics in the PQI convert the field signals into material
density readings and display the results. After the PQI is calibrated,
direct density readings can be consistently obtained. The accurate,
immediate in-situ field measurements help achieve better quality and
longer service life pavements.

NOVA AWARD WINNER
Construction Innovation Forum Founding Directors
The Construction Innovation Forum started in 1986 as a
grass-roots effort to tell good news about construction by recognizing and
encouraging construction innovation worldwide. The first Innovation
Celebration Banquet in March 1989 announced the NOVA Award and issued the
first call for nominations, due September 1, 1989.
The first NOVA Awards
were presented in March 1990 to three construction innovations that had
major impact on the world. The CIF and NOVA Award efforts wereled by the
original officers until they stepped down this year after initiating
strategic planning and reorganization of CIF.
Founding Chair Roger W. Lane, with the steady support
of DTE Energy, established a
vision for construction innovation and recruited enthusiasts and funds
that built CIF. Founding NOVA Award Chair and CIF Vice-Chair Dr. Robert I.
Carr, P.E., created the NOVA Award's unique process and with colleagues at
the University of
Michigan established its foundation in research integrity. Founding
Executive Committee Chair David L. Hamilton has been a strong leader in
all activities, particularly in establishing CIF's financial and
professional integrity. Founding Secretary John A. Doherty led wherever
need was great, including Jury formation, public relations, event
direction, fund raising, and sponsor recruiting. |
