UTTR 9 MSM Igloos

The UTTR 9 MSM Igloos project exemplifies excellence in concrete innovation through its precise construction techniques, advanced quality control measures, and sustainable execution. Designed as a highly specialized missile storage facility, the project required meticulous attention to detail to meet stringent military standards. Each magazine featured dedicated mechanical rooms and was staffed by 15 employees divided into three specialized crews, ensuring a structured, sequential workflow. The project also demanded the exact placement of 50 embeds per structure, requiring an exceptionally high level of precision.

A key contributor to the project’s success was Geneva Rock, an NRMCA producer member, which supplied high-quality concrete tailored to meet the project’s demanding specifications. To optimize efficiency and consistency, an on-site batch plant was established, reducing material transport emissions and allowing real-time quality control adjustments. Geneva Rock’s Quality Control team conducted frequent air and slump checks to maintain mix uniformity and performance consistency throughout the project.

The concrete mix achieved a 5,000 PSI standard with a 100% reinforcing tie-in, preventing shifting during placement. Advanced laser-guided screeds ensured precise floor elevations, meeting a floor flatness (FF) of 40 and a levelness (FL) of 35, exceeding industry benchmarks. Total station LIDAR readings and survey technology were used to verify compliance with tight tolerances, ensuring an exceptionally level and durable final product.

To enhance sustainability and efficiency, the project team strategically minimized material waste, achieving a yield variance under 2.5% on more than 2,000 cubic yards of PCCP. A Class B concrete finish was applied, with all tie holes patched to meet owner specifications. No concrete pavement was rejected or subjected to pay deductions, demonstrating the effectiveness of the project’s stringent quality control protocols.

Despite significant schedule adjustments, the team’s proactive coordination with electrical, mechanical, and precast trades ensured a smooth workflow. Each pour followed a pre-pour checklist, signed off by all trades involved, guaranteeing compliance before placement. Geneva Rock’s expertise in mix uniformity and placement precision played a vital role in keeping the project on schedule while maintaining superior quality standards.
