Central Corridor Light Rail Transit Civil East in St. Paul, Minn

The Central Corridor Light Rail Transit Civil East in St. Paul, Minn., was completed in November 2012. central_light_railThe more than $2 million project includes 14 stations and was designed by Minneapolis-based architect, AECOM. Adolfson & Peterson, Minneapolis, served as the general contractor, and the Metropolitan Council of St. Paul owns the entire complex. The metal features of the project include 31,248 square feet of Double Lock standing seam roof panels in 16-ounce copper and 31,668 square feet of Soldered Hook seam panels in 20-ounce copper by MG McGrath, Maplewood, Minn. MG McGrath was the metal fabricator, installer, and manufacturer for the project and also installed 55, 792 square feet of Trim and Built in gutters in 20-ounce copper. MG McGrath installed Cambridge, Mass.-based Grace Construction Products' Ice and Water Shield over the plywood substrate for the Double Lock panels.

The project was a challenge due to the expedited schedule and the need to finish certain stations on both ends before work on other stations started. There were 14 different stations along a seven-mile-long track with very limited access. The project used approximately 8,500 pounds of solder. Every hook seam panel that was installed needed to be pretinned on all four sides prior to finishing fabrication to insure a quality solder joint.
