safety and security were driving concerns at the Iowa Army Ammunitions Plant (IAAP).
?A 19,000-acre high-security facility, the IAAP’s function is to load, assemble and package explosive components, detonation devices and other explosive charges, including large caliber munitions. To help safeguard the community as well as the facility, Conti installed 5.7 miles of security fence along the southern boundaries of the site.

Conti also built approximately 10 miles of permanent access roads, a 50’ clear corridor along the entire west perimeter, and installed emergency access gates in the south perimeter fence. Site boundaries were difficult to access due to rough terrain, so three of the south crossings required large diameter box culverts weighing 44,000 pounds and requiring a 100-ton crane during installation.

Conti suspended swing gate structures across the Long Creek in alignment with the fence on both sides. To accomplish this, we worked with designers to engineer crossings for 38 ravines, diverting or rerouting entire rivers, which required erosion controls and careful attention around wetlands and wildlife.

Typically a 6-month approval process, Conti achieved National Environmental Policy Act approval in only 30 days.
