Careers in the Aggregates, Concrete & Cement Industries
The Pennsylvania Aggregates and Concrete Association (PACA) is the industry’s unified voice, representing more than 200 member companies across the state.
Creating a unified and strong voice for our industry.
PACA monitors and analyzes local, state and federal regulations and advocates for a balanced approach by the regulators.
PACA builds a bridge between our members and our partners at PennDOT, and the Pennsylvania Turnpike Commission along with Pennsylvania’s construction industry to further the use of our materials to the benefit of the commonwealth.
One of the most effective tools in government relations for an industry is a robust advocacy/grassroots strategy.
In the last legislative session, we contributed over $275,000 to our political champions.

PACA offers comprehensive concrete certification programs for ACI, NRMCA, and PennDOT in the central Pennsylvania area.
Membership has its privileges - most of PACA's events are open to PACA members only.
PACA conducts numerous education and training events during the year.
Choose concrete for your next parking lot project.
Streets built with concrete are built to last, consider concrete for your next project.
Concrete's strong, resilient and the choice for your next building or bridge.
PACA works with the National Ready Mixed Concrete Association (NRMCA) to convert your parking lot or building project to concrete without hurting your bottom line.
PACA drives a member-approved strategic plan to increase market share and engages specifiers and owners on the value of concrete in their projects.
This program provides free continuing education to the design and specifying communities. There are currently four courses available, ranging from 30 minutes to 60 minutes focused on the cement, aggregates and concrete industries. You'll receive a certificate of completion once you pass a quiz. The bookmarking feature allows you to leave the course and resume where you left off when you return.
Delaware Valley Concrete
Stief Concrete
Lorne G. Seifert
Gap, PA
Winner of the Pennsylvania Aggregates and Concrete Association 2014 Commercial Project of the Year, this 1 million square foot facility was consists of tilt-up walls and required over 40,000 cubic yards of concrete and incorporated 7 different mix designs for the following applications:
The perimeter casting slabs were laid down first, with the wall contractor following shorty behind. The General Contractor was hesitant to allow one supplier to ship to both concrete sub-contractors, fearing an inability to keep up with demand, however, DVC utilized its Gap, Kennett Square and Pomeroy plants to properly and effectively supply the job. Management had to ensure that enough stone, sand and cement were on hand to accommodate the sub-contractors continuous demands. Quality control was provided at all the concrete plants and on the job site to satisfy the contractors need to achieve high F values. Sales was present to help coordinate traffic patterns.
Lorne Seifert chose to use a 4000 psi 467 concrete mix for the slab and facilitated its placement with a laser screed. Typical slab placement would begin at midnight and the average pour size was 1000 yards. The wall slabs would often overlap slab placements, which resulted in DVC often supplying both concrete subs simultaneously.
This project involved the efforts of every department, including dispatch to ensure the proper scheduling of drivers and drivers and mechanics changing the lift schedules to work at night. It was a group effort and staff often worked nights into days. Proudly, DVC supplied this demanding project ahead of schedule while continuing to meet the needs of their daily customers.
Concrete, It Just Makes Cents!
Built into a hillside, ICF construction met the challenge of this project site.
Unique pattern and color make this pervious concrete pad stand out.
The project featured tilt-up concrete construction as well as pervious and roller compacted concrete pavements.
Pervious concrete was selected because it offered a life-cycle cost advantage over asphalt.
Pervious concrete allowed the addition to be built, while maintaining impervious cover limits.
The building features Insulating Concrete Form (ICF) construction.
RCC placement met pavement load requirements and need for quick construction turn-around.
Concrete was the answer for the severe rutting that the street was experiencing.
Project is one of only eight strong walls in the US, and the only one poured monolithically
The program is delivered in one (1) module and it should take approximately 30 minutes to complete. You will receive a certificate of completion once you pass the quiz. The bookmarking feature will allow you to leave the course and resume where you left off when you return.
