T他的情况

When the executives of 自由 Property Trust decided to build a distribution center on a piece of property that they owned in Lewisberry, Pennsylvania, they knew just who to call—Hanover-based Conewago 企业公司,., who had recently built the 705,000 sq. ft. 建筑下 门. “We have experience in tilt-up design, which is what they wanted for the project,” explains Don Smith, president of the design/build and general 建筑承包商.

The choice of contractor turned out to be a smart decision 自由财产信托. Using four different concrete construction techniques, Conewago was able, not only to construct the distribution center that its client wanted, but also to make use of some valuable land that would have otherwise been unavailable because of water quality restrictions.

“自由 looks for ways to be environmentally friendly whenever we can. The advantages of using pervious were two-fold. 这是 right thing to do from an environmental standpoint, and it helped with the coverage of pervious versus impervious coverage on the site.”
~ Troy Biggs, Director of Leasing and Land Development, 自由 Property Trust

The building itself is a 550-foot by 1450-foot structure that rises about 45 feet at its peak. Work started in the fall of 2005, with Conewago laying the foundations in February 2006. 大楼的地板是 a traditional concrete floor slab, requiring about 17,000 cubic yards of concrete, and the walls were a tilt-up design that used 4,000 cubic yards. ( company brought in its own portable concrete plant to produce all the types of 这项工作需要世界杯押注平台.)

For the parking areas, Conewago suggested that the owner consider roller compacted concrete as an alternative to asphalt. “世界杯押注平台开始 using roller compacted three or four years ago,” 史密斯说. 当自由 Property Trust wanted to expand their truck parking areas but were over the limit on how much land they could cover on the site, Conewago recommended another innovative product - pervious roller compacted concrete. “和以前一样长 pervious, the township would allow them to pave this additional area.”

“自由 looks for ways to be environmentally friendly whenever we can,” adds Troy Briggs, director of leasing and development at 自由.

“The advantages of using pervious were two-fold. 这是 right thing to do from an environmental standpoint, and it helped with the coverage of pervious versus impervious coverage on the site.”

艺术多于科学

Placing pervious roller compacted concrete - or any type of roller compacted concrete - is a very different process than placing a slab, 史密斯说. “Roller compacted concrete has a low slump and we place it with a special machine paver that is similar to a black top paver,” he continues. “然后, we roll it with black top rollers. It doesn’t look anything like normal 世界杯押注平台,当它下降.” Conewago uses an ABG European style paver and Ingersoll Rand rollers for this work.

“We developed our own methods on how to put it down, mostly through trial and error,” he admits. “It has a lot to do with having the right moisture content and the timing has to be just perfect. 如果你有太多 water in the mix, you can’t get on it with a roller; it won’t 运行 through the paver correctly; if it’s too dry, you won’t get the strength. 它更像是一门艺术 而非科学.”

具体正确的选择

Conewago completed the distribution center in September 2006. “Construction went very well, and I certainly think we’ll find a tenant for the building in the very near future,” comments Briggs. “从世界杯押注平台 perspective and what we’re seeing right now, we’re very happy with how the parking lot looks, and if the wear and tear is there, then we’ve hit a home 运行.

“And from a marketing perspective, I think the concrete is 一个很好的工具. If you think about asphalt, it can become soft with a bunch of tractor trailers sitting there under load. And, you have to reseal asphalt to 保持良好的形象. The concrete should hold up longer than asphalt and if it does, there are long term benefits, not only for 自由, but for the customer. It will cut down on operating expenses to maintain the parking lot.”

“For heavy duty pavement sections, concrete is stronger and typically would require less depth,” adds Smith. “因为沥青的价格 today, concrete is less expensive at the same depth, if it’s placed in an economical manner - and that means roller compacted concrete. 这是一个非常 viable product, and the permeable roller compacted concrete has the added benefit of saving storm water and helping to improve water quality.”
