a history of training and preparing armed forces for every major U.S. conflict
since World War I. South Dakota’s Army National Guard Camp Rapid Campus in
Rapid City has a legacy of providing innovative tactics and strategic thinking
for those who defend our nation.
CampRapid recently used its cutting-edge thinking to
turn a parking lot into an educational opportunity and environmental benefit. As
part of CampRapid’s
regular maintenance and upkeep, Dale Ludens, engineering supervisor for South
Dakota Department of Military and Veterans Affairs, led a project to construct
a 5,000 square-foot parking lot and driveway from pervious concrete at the
Distinguished Visitor’s Headquarters on CampRapid.
Rooted in the Camp’s spirit of leading innovation and promoting education,
Ludens used the project to create an opportunity for the community and local
university to learn about sustainable design and its economic, environmental
and social impacts.
plan and execute the project at CampRapid, Ludens assembled a
team of eager participants: architects, engineers, ready mixed concrete
suppliers, contractors, users and researchers from the South Dakota School of
Mines and Technology (SDSM&T). A set of specific goals were laid forth to
explore the use of pervious concrete in the construction of the lot and
driveway, determine the viability for future developments, identify local
individuals with LEED, and sustainable design credentials as well as promote
innovation and education among interested students and institutes of higher
concrete brought a number of positive attributes and benefits to the project. Unlike
traditional paving materials that do not allow for stormwater to drain through
the pavement, pervious concrete permits three to eight gallons of water per
minute to pass through each square foot of the material. By allowing rainwater
to seep into the ground, pervious concrete can be instrumental in recharging
groundwater and reducing stormwater runoff. Using pervious pavements reduces
the need for retention ponds, swales, and other costly stormwater management
devices. Pervious pavement integrates hardscape surfaces with stormwater
the same time, the durability, strength, and long life cycle of concrete make
it a cost-effective, long lasting pavement solution.
porous nature of pervious concrete prevents runoff containing harmful
contaminants such as oil, grease and other fluids from automobiles, from
filtering directly through into the groundwater. In fact, pervious concrete
systems can be constructed to actually filter contaminants out, helping to
support a healthy ecosystem and recharge groundwater supplies. By constructing
the project with pervious concrete, there was less disruption to the delicate
balance of the surrounding environment at CampRapid,
which includes nearby Rapid Creek.
team participated in layout, mix design specifications, and full scale
construction in October 2008 using a collaborative design approach. Ludens also
secured funding for participation by Craig Phillips, a graduate student at
SDSM&T, to participate in the project by researching mix proportioning
using local aggregates, recommendation of two mix designs, permeability
testing, in-place compaction results and reporting.
not only developed the project for its sustainable benefits to CampRapid,
but intended for it to be an example of how sustainable design and development
can be something that communities share and learn from. As part of this
commitment to continued education, all information has been made available to
other users, designers, owners and contractors in South Dakota whether they
participated in the project or not.
project test information from SDSM&T and tours of the site are available
upon request. Ludens has also made efforts to provide details of their winter
maintenance to allow users to learn from the true local freeze-thaw data.
Ludens developed a presentation to share information about the project with the
design community and was recently a featured speaker at SDSM&T’s Annual
Concrete Conference with over 75 design individuals in attendance and also
delivered the presentation at the 2009 South Dakota Engineering Society Annual
the spirit of CampRapid’s commitment to innovation and education,
Ludens took the opportunity to bring a new technology to South Dakota and ensure that it was, and
continues to be, a learning experience for anyone who takes part. By employing
the use of concrete for sustainable benefits, the project will benefit the CampRapid
community and surrounding environment for decades to come.
