Quiet Contributions to Science

Trumbull-Nelson has Played
a Major Role in the Ongoing
Renovations at one of Dartmouth
College’s key Science Buildings.

The Charles Gilman Life Sciences laboratory at Dartmouth College was built in 1964 to provide a home to the biology department. The building is located near the intersection of College and North Park Streets and connects to the Dana Biomedical Library on the Dartmouth Medical School campus. It was originally right next door to Mary Hitchcock Memorial Hospital, before the hospital outgrew its space and moved to its current location in Lebanon. Since the Gilman building was built, the College’s biology department has grown tremendously.

Today, Gilman contains lab space for 16 professors (along with their technicians, graduate students, post-doctoral fellows, and other employees), computer labs, student common areas, and the Murdough Greenhouses.

Ranging from cellular biologists and geneticists to aquatic ecologists, the diverse labs in Gilman provide space for a wide variety of research interests.
Trumbull-Nelson has been part of ongoing renovations in Gilman for over a decade, and, as such, has played an important role in the biology department’s expansion. As faculty members retire, move away, or give up lab space, the vacated labs are thoroughly renovated to the specs of incoming professors. The process begins with Paul Tougas, Dartmouth’s Project Manager, who works with the incoming professor to determine their needs. He then consults with engineers to design mechanical and electrical specs, and he sends this information to Trumbull-Nelson for an estimate.

According to Tougas, he continues to call on Trumbull-Nelson because they have a lot of experience in the building. “It’s a tricky place to work,” he added. “There are a lot of people and complicated systems at work.

Trumbull-Nelson has shown again and again that they can get the job done well with very little disruption to anyone or anything in the building.”
When Trumbull-Nelson receives the project from Tougas, Cliff Saunders, a Trumbull-Nelson Project Manager with over a decade of experience, enters the picture. Cliff works up the estimate and sends it back to Dartmouth for approval. Once they get the green light, Trumbull-Nelson gets down to work. Cliff explains that the projects “typically start with an asbestos abatement performed by an independent subcontractor, because many buildings that age have asbestos in the concrete panels used in the ceilings.” Trumbull-Nelson typically works with ARC Mechanical and Richard Electric as their primary subcontractors. Both companies know Gilman inside and out from many years of work there.

Meanwhile, Trumbull-Nelson’s millwork shop is busy building the custom cabinets, countertops, fume hoods, and other pieces for the lab. The millwork shop is comprised of five employees who specialize in building custom projects, including cabinets, casework, moldings, and trims.

This capability enables Trumbull-Nelson to be highly efficient. After the individual cabinets are built and finished in the shop, they are transported to the lab and assembled into complete units along with the fire- and chemical-resistant epoxy countertops (which are made by Fisher Scientific). Custom-designed pieces like these are very labor intensive, but the end result is a beautiful, functional space that perfectly matches the occupant’s needs.

Much of Trumbull-Nelson’s role in the Gilman projects is project management. Steve Locke and Tom Beckett oversee Trumbull-Nelson’s operations at Gilman. They manage the various subcontractors as well as the millwork built by Trumbull-Nelson itself. Finally, as the end draws near, final details are ironed out with the incoming professor to ensure that the space meets his or her needs exactly.

The current Gilman project is a renovation of an 1,163-square-foot lab for Ryan Calsbeek, an Assistant Professor just hired by Dartmouth. An ecologist, Professor Calsbeek’s research focuses on the ecological or evolutionary consequences of natural and sexual selection, using lizards as the primary study tool. While the lizards themselves will be housed in the Animal Control Facilities in the basement of Gilman, Professor Calsbeek’s research led him to request specific features in his lab.

“We do a combination of field and bench work, so part of our lab is pure molecular biology—lots of open counters and shelves above the desks. However, the center island workstation has benches on one side with computer stations on the backside. This creates a multi-use area where we can have lab meetings, analyze data, and work away from the ‘wet’ portion of the lab,” Calsbeek explains. Having researched lizards in both the Bahamas and California, Professor Calsbeek and his students will continue to study these lizard populations while also branching out to other areas of interest. Initially, the lab will be occupied by Professor Calsbeek, his technician, and his dog (the “lab Lab”), but the space will quickly fill with grad students and post-docs.

At roughly 1,000 square feet per lab, none of the Gilman projects are especially large, but the various pieces of the puzzle mean that each lab takes approximately four to five months to renovate. With at least eight Gilman labs renovated by Trumbull-Nelson in the last decade, there is almost always a Gilman project in the planning stage or under construction. Using a combination of subcontractors and in-house experts, Trumbull-Nelson’s vast project management experience means that disruption to the building and the biology department in general is kept to a minimum, and incoming faculty can quickly move into their new spaces and begin their careers at Dartmouth.
