111 East Grand, a 66,800-sf, four-story multi-use building, is currently under construction in Des Moines. The building is the largest dowel laminated timber (DLT) project in North America. DLT, manufactured by StructureCraft, will be used for the floor and roof assemblies. The columns and beams will be made from glue laminated timber.

DLT panels are made from stacked softwood lumber boards that are friction-fit together using hardwood dowels. DLT doesn’t contain any glue, VOCs, or metal nails, meaning there is no off-gassing.

The project is a collaborative development between JSC Properties, Rypma Properties, Christensen Development, and Ryan Companies. In addition to working on the project, Ryan Companies will also be one of the building’s first tenants as the firm will move its Des Moines office team into the project. Three additional tenants have secured leases as well: Neumann Monson Architects (the architect of record for the project), St. Kilda Surf + Turf, and West Financial Advisors.

The project is slated for completion in Spring 2019.
