Gillmor Science Hall 


The Gillmor Science Hall is the cornerstone of a $10 million massive addition to the Heidelberg College’s existing science facilities and home to the nationally renowned Water Quality research facility. This was a 3-story, 42,000 square foot addition, stone veneer building constructed with 68 – thirty-inch diameter caissons varying in length of 12 to 20 feet. The envelope consists of a structural steel frame, clay tile roof with copper gutters and downspouts and showcase a grand curved wall. The facility houses a student lounge and numerous labs and classrooms including cell molecular, microbiology genetics, field biology, anatomy, biology research, aquatic biology, organic analytical, suspended solids, chemistry, zoology, and botany rooms. Challenges The biggest challenge faced during the preliminary construction phase was re-routing and replacing the college’s main communication line and power service (12,000 volts) to the Science Building. Originally these lines ran overhead through the new building site and had to be kept in service at all times. Dust and noise levels had to be kept to a minimum during certain hours as the adjacent buildings are offices and classrooms that were in use throughout construction.   The budget had been established seven years prior and no additional funds were available.  By working with “hand-selected” quality subcontractors and the Architect, many value engineering ideas were incorporated to meet the rigid budget constraints.   Tuttle Construction was awarded the 2005 Build Ohio Award for New Construction Under $10 million for this project.
