The Boulder County Parks Department is located next to a municipal airport making sound suppression the main consideration when ARXX ICFs were selected for this project.  Building with ARXX ICFs allowed the owners to exceed the STC code requirements for this project and they were thrilled when they were able to use their own crew which previously had no experience building with ARXX ICFs.  After taking the 1 day training course, the crew was able to quickly erect the ARXX ICF walls and still complete the project on time.  The result was an ARXX ICF project that won an ICF Builder Award for Best Light Commercial Building.
