AIA Aaron Twedt

AIA Aaron Twedt serves as a key procurement lead for the City of West Des Moines, overseeing civil infrastructure acquisitions aligned with the municipality’s mission to modernize public utilities and enhance community resilience. In this role, Twedt manages the full lifecycle of contracts for municipal capital improvement projects, with a primary focus on roofing systems integral to public buildings, stormwater infrastructure, and facility maintenance. His procurement activities directly support the city’s long-term infrastructure sustainability goals, ensuring compliance with state and federal standards while prioritizing durability, lifecycle cost efficiency, and code adherence in all awarded contracts. Twedt collaborates with a network of licensed roofing contractors and specialty civil works vendors who possess proven experience in commercial and municipal building envelope systems. While no single contractor dominates his portfolio, he consistently engages firms with demonstrated expertise in single-ply membrane systems, built-up roofing, and waterproofing applications for public facilities. His contracting approach emphasizes performance-based specifications, pre-qualification requirements, and post-award performance monitoring to ensure quality outcomes and lifecycle reliability. Twedt’s procurement strategy reflects a non-set-aside orientation, with 100% of acquisitions conducted under general competition without socioeconomic set-asides such as 8(a), HUBZone, or SDVOSB preferences. This approach prioritizes technical capability and price competitiveness over socioeconomic classifications, consistent with the city’s operational focus on infrastructure performance rather than socioeconomic targeting. His primary procurement focus is centered on NAICS 238160, Roofing Contractors, reflecting deep expertise in building envelope systems, waterproofing technologies, and roofing material specifications for municipal assets. Twedt specializes in procuring commercial-grade roofing installations, repair services, and maintenance contracts for city-owned facilities, including public buildings, recreation centers, and administrative structures. His technical domain expertise lies in material selection, warranty compliance, and energy-efficient roofing solutions that align with municipal sustainability objectives.
