When Hartman Concrete saw the plans for the proposed Fulton Bank in Harrisburg, they were intrigued by the use of the pervious asphalt in the parking lot. Having seen several pervious asphalt projects in the past, they knew that pervious asphalt paving in the city would be a maintenance nightmare for the building owner. After discussing the project with Ryan Coudriet, LEED, AP from Pyramid Construction, the general contractor, it was decided to provide a concrete alternate price for not only pervious asphalt, but for all the asphalt paving on the project. Once the bids were received, not only were concrete’s life cycle costs less than those of the asphalt, the initial costs were also found to be below that of the asphalt alternative.
“GreenWorks Development selected pervious concrete not only because it met our sustainability standards for “green” construction, but because it also met our rigorous standards for durability, ease of maintenance and installation cost. ”
The project itself was more of a challenge than normal because of the tight constraints working in the city and dealing with city traffic. With asphalt paving, a tractor trailer would be required to drop off a paving machine, a dump truck would be required to haul the paving material, the paving machine would be required to place it and the tractor trailer would have to make a return trip to pickup the paving machine. All of which adds traffic congestion. Since the pervious concrete, supplied by Pennsy Supply, was placed with wet benches, all that was required was a concrete truck to deposit the material at the site. Placement of the material was facilitated by hand with the use of a roller screed. The pervious concrete was delivered quickly, and with little traffic interruption
Greenworks Development, the owner of the project couldn’t be more pleased with the project. “GreenWorks Development selected pervious concrete not only because it met our sustainability standards for “green” construction, but because it also met our rigorous standards for durability, ease of maintenance and installation cost” Said Bobbie Van Buskirk, Vice President, GreenWorks Development.
