Hillsboro Hops Stadium

Project Completed: Estimated Spring 2023

Ron Tonkin Field Improvements

The City of Hillsboro Public Works Department partnered with AKS for its Hops Stadium expansion and new stadium design project. AKS has a long history of teaming with the City of Hillsboro, which helped to foster efficient communication regarding scope needs and timelines on such a technical and time-sensitive project. This project included conventional surveying, terrestrial scanning, drone-collected lidar, and high-resolution imaging.

This unique project came with many challenges, the first of which was scheduling. During the survey work, the stadium and ball fields remained fully operational. Our team worked closely with the facilities coordinator to ensure data was collected during off-hours and not high-traffic times. Thanks to our cutting-edge technology, we met all the project challenges and delivered quality data on an accelerated timeline.

AKS used conventional methods (robotic total station paired with GPS RTK) to establish a permanent control network throughout the site that would be precise, persistent, and unobtrusive to the public. This control network supported boundary work, exterior hard surface mapping, drone data, and scanning.

Terrestrial scanning created point clouds within and around the stadium to provide critical tie-in information for the structural engineering team. The stadium consists of a ground level, a main concourse level, elevated box seating, and intricate overhangs throughout. The point cloud data allowed the structural team to have all the data they needed as they went through their design process.


Since the ball fields are frequently used and must be pristine, our team used drone imagery and lidar to map features in these sensitive areas. Care was taken with public and private locators to use chalk-based marks instead of paint to minimize the impact on the facilities. The high-resolution imagery allowed for aboveground infrastructure to be mapped efficiently and with little impact on the ground.
