Client Context
- 5
- stories, a different plan on every floor
- 24/7
- library, never closed
Clemons Library is named for Harry Clemons, the university’s librarian from 1927 to 1950. The heavily used five-story, pyramid-shaped building is open around the clock, has a different floor plan on every level, and a complicated storm piping system serving the roof and several patio areas.
The storm piping runs above other piping, ductwork and electrical conduit, which makes any failure hard to reach. The last straw came when a 4-inch cast iron pipe burst in the first-floor ceiling during a heavy rain and the flood took out four rows of bookshelves before it could be repaired.

Strategic Approach
- 01
A long campus relationship
Dynamic Drain had inspected and rehabilitated many manhole-to-manhole pipes on the campus between 2010 and 2015.
- 02
Inside the building footprint
Since 2016 the company has lined pipes inside buildings, in walls, ceilings and under slabs, which prepared it for this system.
- 03
Two phases
The work was completed in two phases over two years, on schedule and on budget.

- 01Evaluation studyThe system is mapped, inspected by camera, and every section is condition-graded.
- 02Prioritized findingsGrades are weighted by system risk and turned into a plan, most critical sections first.
- 03RehabilitationTrenchless CIPP lining of the sections that matter most, without full pipe replacement. Access requirements are confirmed during the evaluation.
