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.

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.
Union Quarries
Macri Concrete
Hartman Concrete
Carlisle, Pennsylvania
At some point in a company’s growth, more space becomes a priority. York Building Products – Bonnybrook Quarry location was no exception! At the time of construction, the office space was approximately 30’ x 50’ and housed the weighmaster, dispatcher, and all administrative and accounting offices.
A future project recommendation would be integrating ICFs for subgrade stub-wall construction. Additionally, during the selection of mechanical subcontractors, we would suggest ample time to educate and review design criteria for each application, as concrete walls do pose a hurdle to these contractors.~ Dan Ridenour, Director of Engineering and Planning – PA Operations, York Building Products

The company opted to be their own general contractor for the project. We stopped by to speak with Dan Ridenour (Director of Engineering and Planning – PA Operations) about the process and their experience.
What went into the decision to build the office with ICFs?All construction types were evaluated. An existing trailer stood in the location of the new office and was first evaluated for rehab to fit our needs for more office space. When it was determined that it was not large enough to accommodate our needs, we evaluated stick, modular, and pole building construction in addition to ICF.
ICF construction proved to be, not only the favorite, but also the most cost-effective solution.
Who designed the building? Did they have prior experience with ICFs?The building was designed in-house and was reviewed by Akens Engineering. While there was no prior experiencewith ICFs, construction and related design knowledge proved beneficial.
Were there any hurdles associated with using ICFs versus conventional framing?It was challenging finding a contractor that was experienced in ICF construction. The construction process is different when utilizing ICFs and how utilities (electric, plumbing, heating) are run must be given consideration. Choosing to use ICF decking (Insuldeck) to construct the roof added to the challenge. We opted to go with a concrete roof in order to accommodate future vertical expansion of the building.
Who was the building contractor, and did they have any prior experience with ICFs?Specific to the ICF install, walls and roof, Macri Concrete was our chosen contractor. This was Macri’s first ICF project.
What is the square footage and how many yards of concrete did the project use?The total office floor space is 2,100 sqft. We used approximately 874 cubic yards of concrete. Recognizingsustainable construction practices, the concrete incorporated slag and Type IL cements.
What contractor did the decorative flatwork concrete?Hartman Concrete performed all decorative concrete construction, including both exterior and polishing andstaining of interior floors.
Please offer any additional comments you wish regarding the project and recommendations for future commercial or residential construction incorporating ICFs.As is common in ICF construction, all exterior walls utilized ICF. Where this build breaks from the norm, is the use of ICFs for interior wall construction and the roof. Over 50% of the interior wall and 100% of the roof construction utilized ICFs.
A future project recommendation would be integrating ICFs for subgrade stub-wall construction. Additionally,during the selection of mechanical subcontractors, we would suggest ample time to educate and review designcriteria for each application, as concrete walls do pose a hurdle to these contractors.
A new space was needed to provide for these functions, but also to include room for training, general meetings and conferencing, quality control and future growth.
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.
