Senior Project Manager - Transportation

PetersenM@AyresAssociates.com
I joined Ayres in 1999 as a transportation engineer and have been a project manager for more than 10 years. My primary responsibilities include project management, urban and rural state highway design, report preparation, utility coordination, and agency coordination. I also work with design software.
I have written several pavement type selection reports, environmental reports, and design study reports and am very familiar with the plans, specifications, and estimate (PS&E) process. I have put together many PS&E packages and am very familiar with the Wisconsin DOT's Facilities Development Manual (FDM) and the AASHTO Roadside Design Guide. I have managed several WisDOT projects and have overseen large construction projects for WisDOT and various counties. I have used my construction experience to improve roadway designs and anticipate potential problems early in the design process.
I'm dedicated to working with local officials and business groups to make sure projects meet their needs in the final layout and during construction.
