Mainline's crew that was assigned to our project were professional throughout the project and assured that the City's expectations were met and exceeded. In spite of numerous project challenges which included confined site conditions, groundwater/creek seepage, dep bore pits, large cobble to bore through and period of extreme cold weather, Mainline Contracting completed the project with quality workmanship, on time and on budget. 
 

Kyle Mathis, PE,

Last summer we had the experience of reconstruction on our street. Fortunately for the city, Mainline Construction and Complete Concrete made it as painless as possible. I hope the city continues to use these two fine companies often. 

Milton & Rhonda Wright,

Mainline Contracting made an outstanding effort to exceed compliance expectations for the installation of the drainage improvements, crossings and box culverts for the Back 9 holes at the Elkhorn Ridge Golf Course. The site compliance record at this time is outstanding and is clearly a result of good team effort. 

Mainline Contracting Inc did an excellent job working with the residents affected by the project and providing the resources required to overcome the harsh weather conditions. They kept a positive attitude and were able to meet the substantial completion date set for the project without sacrificing the quality or workmanship of the construction. 

Hiene Junge,
