AMP World Headquarters Parking Structure
Project: AMP World Headquarters Parking Structure
Precast Concrete Supplier: Nitterhouse Concrete Products, Inc.
Structural Engineer: Clapp & Holmes
General Contractor: Lobar, Inc.
Location: Harrisburg, PA
Products: DCI® S Corrosion
The Challenge . . .
When AMP Inc. was building a new world headquarters, they needed a parking
garage that had an impressive design and was built to last. Because parking
structures in northern climates get repeated doses of de-icing salts,
and cars laden with road salt drop salt onto parking decks, preventing
corrosion is a prime concern.
The Solution . . .
"Working with the architect, engineer and Grace Construction Products
at the start of the project, we were able to carefully consider the design
and requirements of the structure to develop the appropriate mix", said
Larry Shoemaker, Nitterhouse Concrete Products. DCI S was included for
corrosion protection in all of the precast double-tee deck panels. Daravair,
a liquid air-entraining admixture, was used to provide freeze-thaw resistance,
yield control, and finishability performance across a full range of concrete
mix designs. In addition, Daracem 19 superplasticizer was included to
give the mix workability at a very low water/cement ratio which is ideal
for use in parking decks.
