Lunda has built a solid name in the Industry with an uncompromising pledge to achieve the highest standards of Engineering and Excellence, with the Safety of the workforce and traveling public being the highest priority.
Demolition
Lunda Construction was part of the Joint Venture, Marquette Constructors (MC), which was awarded the project to rebuild the Marquette Interchange in downtown Milwaukee, WI. The construction of the new multi-level freeway interchange required complex staged structure demolition and new girder erection above and below existing and new structures while maintaining interstate traffic. The project also required working over active railroad tracks, river canals, We Energies’ Power Plant operations and above ground steam lines.
The Mitchell Interchange is one of WisDOT’s most complex projects in state history. The project is a fast paced complex staging project. Multiple crews, multiple shifts working up to seven days a week were used to meet the aggressive schedule. Lunda’s contribution to this joint venture was completing the retaining wall and bridge structure work on the Mitchell Interchange. Thirteen new bridges will be built during the life of the project including flat slab, steel and steel tub bridges, and prestressed bridges. Retaining walls up to 1,600 feet long have also been completed by the Lunda crews.
Walkways
Project was to demolish 1100 lineal feet of existing boardwalk and build a new boardwalk. The new boardwalk consisted of 1100 lineal feet of new concrete bulkhead, 14,000 square feet of concrete walkways, 4600 square feet of pile-supported composite-decking boardwalk, 1830 square feet of pile-supported composite-decking finger piers and 1820 square feet of structural steel-supported composite-decking boardwalk.
The most complex and highly anticipated structures were the three new tunnels built using specialized drilling techniques. WisDOT specified secant shafts for the tunnels. The shafts vary from 40-65 feet in depth. The area in between the shafts was excavated and prestressed girders were placed on top of the secant cap. The tunnel decks were poured and the roadway sections were completed inside the tunnels. The tunnels have a complex lighting and a fire protection system. Because of staging, all three tunnels had to be built in sections. Once one section of the tunnel roof deck was completed, a new pavement section was placed on top of it and the new traffic pattern soon followed. This opened up the next tunnel section to be constructed.
This project was a 5.5 mile pavement resurfacing and bridge rehabilitation/replacement contract including two twin 18 span deck replacements over the Fox River, two complete structure replacements over local streets, and concrete masonry overlays on 22 bridges.
