RANI redesigned the aging stormwater system, provided erosion control and concrete jointing services. The tight corridor along the Lowry Tunnel posed many challenges, including drastic elevation changes, construct-ability issues associated with deep structures and connections to large existing stormwater structures. More than 100 manhole structures were designed with approximately 2 miles of pipe.
RANI provided survey and civil design services to develop a stormwater management plan, erosion control plans, and concrete jointing plans as part of reconstruction of the Hennepin-Lyndale Avenue intersection.
Professional services included:
- Topographic survey of utilities, intersecting roads and 30 feet into adjacent properties
- Stormwater management system design, including storm sewer design calculations and modeling using GEOPAK
- Erosion control plans
- Concrete jointing plans
- Preparing construction plans, profiles and specifications
- Preparing the construction cost estimate
