• ISG values Helix’s responsive and smooth collaboration from project start to finish.
• Helix® provided engineering support to analyze options for replacing traditional rebar in the slabs with their proactive concrete reinforcement technology. ISG provided slab thickness, rebar layout, and design loading information that Helix® used to develop options for replacing a large section of the facility foundation with Helix® Micro Rebar™.
• ISG used product information provided by Helix® to collaborate with the contractor to ensure the client received a slab that met both performance and cost specifications.
• The design included an impressive employee café with a polished concrete floor that incorporated Helix material rather than a traditional concrete and rebar application.
