Creating Space Underground





Tunneling Success at Denver's Platte to Park Hill Project is a Team Effort

William Gleason, Senior Editor, T&UC

The city of Denver, CO has experienced extreme growth in the past decade, with the population of the city topping more than 700,000 people in 2018. The current storm water drainage system was put in place in the early 1900s and has not been able to keep up with the growth of the city.

When it rains north and east of the city, the runoff goes toward the South Platte River. With the dense population and sometimes severe thunderstorms in the summer, the city has experienced significant flooding that not only endangers lives of residents, but some of the storms have caused millions of dollars of property damage.

Eric Michal, PE in downtown San Francisco continues with taller structures and deeper more complicated basement excavations. Tight urban sites in the city pose several challenges ranging from existing underground utilities, adjoining structures and difficult geotechnical conditions. Brierley Associates teamed with Malcolm Drilling Company to deliver design-build micropile foundations and temporary support of excavation and underpinning systems for the 706 Mission project, a new 480-ft tall, 43-story residential high-rise tower that is currently under construction.
