The City of Fayetteville, Arkansas needed a new
library. Construction for this new multi-story
building began in downtown Fayetteville early in the year 2002. The project was
located in a residential area with the Fayetteville City Hospital less than a
block to the south. Restaurants, homes, health care facilities and other city
administrative offices bordered this project. Residences are located literally
across the street from the construction site.
No rock that could not be excavated
with conventional equipment was anticipated. Crossland Construction out of
Columbus, Kansas was the general contractor in charge of building the new
library. Ground had been broken and the excavation and construction was well
underway when they struck rock.
Hydraulic hammers and ripping equipment
proved to be too slow and costly. A decision had to be made on how to extract
the rock in this sensitive downtown urban safely and cost effectively.
Crossland Construction contacted Dykon Blasting Corp. to do an evaluation of the
possibility of using Precision Controlled Blasting as a means of fragmenting the
rock for excavation.
Blasting Corp. evaluated the job and the decision was made to blast the rock for
this project. Precision Controlled Blasting techniques were used to fragment
the rock for this job while not doing any harm to any of the surrounding
structures that bordered this project. This kind of precision in blasting
involves the accurate calculation of the precise quantity of explosive to
fragment the rock and the precise distribution of the explosive within the rock
to achieve rock fragmentation suitable for excavation by ordinary equipment.
A public meeting was held to inform the
nearby residents of the plan to blast the rock for this project. Concerned
homeowners were told of the decision to blast and were told the measures that
would be taken to protect their property from damage. The homeowners were a joy
to work with.
During the course of this project, we
experienced something that few blasting contractors ever
get the opportunity to enjoy. The blasting started in the center of the project
and worked westward towards the residences on West Avenue. Once we reached the
western perimeter of the blasting, we turned northward and trimmed the remaining
shots off in that direction. When we reached the northern perimeter, we then
turned East, working parallel with the north line of excavation. When we turned
east with the project, the blasting became further from the residents on West
Avenue and started approaching the residents on Mountain Street. One of the
homeowners on West Avenue went to talk to an elderly lady that owned a home on
Mountain Street. She was extremely nervous and worried, but the homeowner from
West Avenue spoke in our behalf and comforted her.
at Dykon Blasting cannot find the words to properly express our gratitude to
homeowners that act on our behalf in this manner. The residents and citizens
that surrounded this project were supremely understanding and cooperative. This
alone was the single greatest factor that helped to make this project a complete
success. The blasting is finished and we have gone on to other projects, but we
will never forget the level of trust and support from the residents we were
blessed with on this project. Our deepest heartfelt thanks goes out to all the
residents, workers, citizens and onsite contractors who worked hand in hand with
us towards the completion of our portion of this project.
We would also like to extend our thanks
to Crossland Construction and the City of Fayetteville, Arkansas. We hope
someday to be able to work with them again in the future.
