Project Details

This project included a 37,000 SF expansion to the existing Adler building. The expansion houses classrooms, a new gymnasium, and fitness center. The construction of six new tennis courts was also included in the project.

After a complete study of Spring Run to determine the location of the 100-year floodplain, stormwater for the project was managed with four Bio Retention areas placed in strategic locations around the perimeter of the building. Also included are two underground pipe detention systems, and a series of infiltration trenches. Managed stormwater is then released directly to Spring Run and the existing stormwater conveyance system.

Project Uniqueness/Challenges:

  • Relocation of all existing utilities, location of private utility service lines, and existing stormwater conveyance pipe provided design constraints.
  • The schedule of construction was dependent upon PSU Altoona’s schedule as the existing building continued operations through most of the construction.


We have teamed with Keller Engineers on several design-build projects for PennDOT. When selecting a designer, the more critical factors are trust and competence, more so than a low price. If your designer makes a mistake in quantities it can cost you a lot of money. We have stayed with Keller Engineers because we trust them to provide competent service at a competitive price.  S.
