Structural Engineering
The science and art of putting a roof and/or floor around occupancy -- the backbone of the design concept. Providing a solution that economically addresses a structure’s use, while providing optimal durability and architectural distinction.

Projects:
Lot 76 Parking Ramp, UW-Madison
Madison, WI
A four-level, four-bay, 1,285-space parking structure meeting the University’s need for capacity, security, architectural harmony with surrounding buildings, and functionality within the University’s alternative transportation effort.
Dane County Regional Airport
Madison, WI
The original 1360-car parking ramp was designed in 1995 for future vertical expansion in 2002. Parking demand increased four years earlier than anticipated, so the project team had to act quickly and construct the parking ramp's 480-car, 138,400 sf addition in fewer than 10 months. Efficient scheduling contributed to the success of the project.
Camp Randall Stadium, UW-Madison
Madison, WI
A four-year renovation and addition project with unique engineering challenges and creative solutions. The challenge was to develop a connection that avoided field welding and bolting and used a minimal number of standard pieces. The solution included a pin assembly that allowed each truss to be assembled with a pin and slotted plates. A&O’s employment of the pin assembly for the five different truss connections provided these advantages:
• A clean and simple, yet visually
impressive design
• Multiple connections with a single
solution
• Smooth and efficient continuation of
constructions, since the structural
system contained standard,
domestically-available steel sections
• Labor and materials cost savings,
since the solution maximized steel
shop fabricated work and limited
the amount of field work necessary
for installation
• A new technique – both efficient
and cost effective – for consideration
by other structural engineers
when addressing truss connections
Cherry Street Ramp, Green Bay, WI
A new seven-level, precast concrete parking structure that serves the downtown business in Green Bay, Wisconsin. The ramp has been designed for 801 cars, a drive-thru bank, and approximately 15,400 sf of commercial/retail space to be developed at a later date. Exterior column and panels have a variety of concrete and integral brick finishes. All stairs and elevators are on the exterior walls and have full curtain wall glazing for maximum visibility.
The site was narrow, but the project required accommodations for future commercial space be integrated into the design. This required the use of an aggressive speed ramp. With a potential bottleneck intersection, it was subject to extensive modeling during design to assure adequate performance once constructed.
