Celebrating CMHA’s First CPI Certified Installer

On July 1, CMHA unveiled its new Concrete Paver Installer (CPI) certification program, a significant milestone in our commitment to enhancing industry standards. This program offers comprehensive competency testing in paver installation methods, equipment, materials, safety, and design. Notably, the CPI program represents our dedication to transitioning all our education certificates into recognized certifications under the International Organization of Standards.

Below is an interview with Terri Childs, owner of Nature’s Way Landscaping and the first certified installer under the new program. In this Q&A, we delve into Terri’s background, his experience as an installer, and his valuable advice for those considering enrollment in the CMHA CPI Certification program.

Q: How did you get into the industry? How long have you been an installer? A: My wife was on maternity leave 32 years ago and I had two part-time jobs. At the time, we thought I could run a part-time business to earn more for the family, so I started Nature’s Way as an Organic Lawn Care company. We slowly grew over the decades and now the company handles landscape and hardscape projects. 

Q: How have you applied what you learned from the CPI course on a job site to solve an issue?
A: 
I have not used specific information from the course, but rather the entire installation process from the course and we rarely run into issues. I have used CPI knowledge to help non-CPI-certified companies with their installation issues. Sometimes I get questions and concerns from clients about other companies and I always use the information from the CPI course and CMHA research to answer their questions and concerns.

Q: What does this certificate mean to you and what made you want to continue to renew with CMHA? A: It shows our clients we follow current Industry Standards and the certification means we have achieved a certain level of expertise. The certification separates us from the non-certified installers in the area. 

Q: What are your thoughts on the transition CMHA is taking with CPI and why is it important to be certified in this industry?
A: 
I am not sure I fully agree with separating the course and the certification, but it is the normal way of doing it with other industry certifications. I benefited when I became a Certified Landscaper, I did not have to take the course, just pass the exam and prove my hours of work in the field, like the way the CPI certification is set up now, I think in the end we will serve many more installers. 

Q: What would you share about the CPI program to encourage others to consider taking the course? A: For such a low price and the ability to provide proven construction methods, why not? Your staff will feel empowered when they take the course and get certified.

Q: What was your experience when applying to the Grandfathered Certification Program?
A: 
It was simple. The staff quickly processed my application, which was a pleasant surprise.

ICPI Releases Tech Spec 24 on Structural Design of Slabs and Planks

ICPI Tech Spec 24 entitled “Structural Design of Segmental Concrete Paving Slab and Plank Pavement Systems” provides the amount of vehicular traffic on a range of slab and plank dimensions.

Base options are compacted aggregate or concrete over an aggregate subbase. Designs specifically address weak soil subgrades and lifetime traffic loads up to 30,000 equivalent singe axle loads. Unlike interlocking concrete pavement, slabs and planks offer little if any interlock to spread loads. Therefore, traffic is limited to occasional use by cars and light trucks. Developed from modeling and full-scale load tests, the design method provides tables from which designers can select paving unit dimensions and soil strength to determine the appropriate traffic level. The easy-to-use bulletin aimed at landscape architects and civil engineers is available for download.

ICPI Presents Design Guidance for Slabs and Planks Subject to Vehicular Traffic

With the increasing number of ICPI members manufacturing and installing concrete paving slabs and planks, a key design question is how much vehicular traffic can they take? While most at-grade applications are for pedestrian use only, designers are pushing slabs and planks into a growing number of vehicular applications unaware of the risks for damage. On March 31, 2022, Bryan Horr, P.E. presented the latest guidance on the limited amount of vehicular traffic slabs and planks can accept. Key points in his presentation included:

  • Differences between slabs and pavers

  • Design elements and applications for slabs and planks

  • Modeling and full-scale load testing outcomes (see below photo)

  • Structural design guidance in the new ICPI Tech Spec 24: Structural Design of Segmental Concrete Paving Slab and Plank Pavement Systems

 The recorded webinar is available to view.

Hardscape Installation Draws a Crowd at the National Collegiate Landscape Competition

From March 16-19, 2022, students from across the United States gathered at the North Carolina State University for the 46th Annual National Collegiate Landscape Competition (NCLC) organized by the National Association of Landscape Professionals (NALP).

The NCLC is the largest national competition and career recruitment event for college students studying horticulture and landscaping, with approximately 530 students from 41 colleges competing each year in 31 events. Students demonstrate their skills in tree climbing, patio building, identifying horticulture specimens, skid steer operation, sales presentations, exterior/interior design, irrigation troubleshooting, wood construction, and more.

On March 16, students attended workshops to sharpen their knowledge and abilities on a wide range of topics related to the landscape industry and completed qualification exams that would allow them to participate in the competitive events. A Career Fair started on March 17 which several ICPI members participated including Belgard, Ewing, Grunder Landscaping Co., Lifescape, Para Space Landscaping, Permaloc, SiteOne, Southview Design, and Weller Brothers Landscaping. In the afternoon competitive event briefings were held to inform the students about the details, procedures, and requirements of the events. On March 18 each student was allowed to participate in up to three events. ICPI staff provided support for the workshop, competition briefing, and hardscape installation event.

In the Hardscape Installation event, 31 teams constructed an 8 ft x 8 ft interlocking concrete pavement patio in a basketweave pattern with a soldier course and L-shaped seat wall. Teams were given 110 minutes to compete the task. All teams did well, and each fought the clock right to the very last second. Afterwards each installation was evaluated by a team of judges and scores were awarded for accuracy, structural soundness, site cleanup, and safety. In the end the following students/schools were named the Top 3.
