111 East Grand Office
The First DLT Office Building in North America
PROGRESS UPDATE: We have completed the installation of the structure in 3 zones, using DLT panels and Glulam post & beam. See below pictures and stay tuned for more finished pictures!
111 East Grand Office will be the first spec office building in downtown Des Moines in over a decade, with a prominent location next to city hall. We are the design-builders for the timber superstructure, working alongside Neumann Monson architects. The 4-storey mass timber building will have retail at the first level, with 3 levels of commercial office space above. The structural gravity system is DLT (dowel-laminated timber) panels over Glulam post and beam substructure. The lateral system is pre-cast concrete walls and core, making a fully pre-fabricated superstructure which will be installed very quickly.
The project will be the first DLT office building in North America, and the largest DLT project in North America once built.
StructureCraft won the project after submitting a response to request for Design-Build proposals in Fall 2017, joining the team of Ryan Co., Neumann Monson and Raker Rhodes. We were chosen for our extensive engineering and construction experience in large North American mass timber jobs, as well as our turnkey delivery method. Our engineering role is to take the timber superstructure from schematic design to detailed fabrication design, sealing the drawings with our in-house licensed P.E.
This project will display a simple, efficient, yet elegant mass timber design leading to a fast site installation.
Each DLT panel was fabricated with shallower boards at its edges to create chases for housing electrical conduits.
