Carlton Fire Station was two different building types. The apparatus bay was fabricated from a pre-engineered metal building and the administration/kitchen/training was constructed with wood framing. The two buildings were separated with seismic joint so they could act independently during a seismic event. The only engineering we did on the apparatus bay was the foundation and mezzanine in the apparatus bays. Originally it was to be designed as a five bay station, but budget cuts reduced it to a four bay station with only one mezzanine.

The mezzanine was design as a self-supporting structure as well, taking all vertical and lateral loads independent of the metal building structure. The structure was plywood floor sheathing on I-joist framing to 2x wood studs and plywood shear walls. Because it was a wood structure and it was small enough, it tied into the main wood building. Therefore, it shared a shear wall.

It was a fairly conventional wood structure, with press-plate wood trusses in the roof and 2x wood studs with plywood sheathed shear walls. Because of that, the building itself presented very little field construction issues.
