My effort to fill the six new industrial spurs in the congested area geo-north, RR-East, of the Eugene Depot brought me to the spot designated for the BiMart warehouse. As I noted in the first of the posts in this series (https://espeecascades.blogspot.com/2021/08/rr-east-eugene-development-1.html), I consulted multiple sources to identify what industries I would model. Most of the industries appeared on the 1977 SPINS (Southern Pacific Industrial Numbering System) diagrams for Eugene. Given our positive view of BiMart here in Oregon plus a family tale we delight in, BiMart immediately became a winner.
BiMart is a local-to-the-Pacific-Northwest discount retailer, much like Costco. Founded in Yakima, Washington, BiMart quickly became an Oregon institution and soon headquartered in Eugene. I searched the internet for more information and found their current headquarters and distribution warehouse on Google Earth satellite view. The current warehouse is served strictly by truck, but that 1977 SPINS document clearly identified a BiMart warehouse as an SP customer. I suspect BiMart changed warehouse locations to a much larger truck facility as their business grew and transportation shifted to trucks. The current satellite and street views are of a different warehouse.
I chose to model a typical warehouse from the mid-century. Concrete tilt-slab wall construction and bowed roofs were very common. This structural form lends itself well to foam-core model construction as I have done on a number of other structures. The bowed roof added a bit of challenge as I wanted to make a hipped version of such a roof—another common feature. An added challenge for my model was the need for a diagonal cut along the back of my structure to fit it against the wall while having the rail side parallel the spur track.

I built my model in two major sub-assemblies. The walls were my conventional foam-core construction with a cardstock siding laminated to the core structure walls. I simply painted the cardstock a creamy off-white. I captured the BiMart logo from the back side of a receipt and then printed it on one of the painted cardstock sheets. The columns were strips of plastic, painted the same wall color. Both the roll-up freight doors and personnel doors came from my favorite Clever Models steel structure pack. Other bits of styrene from my scrap bin provided the freight docks and personnel stairs.

Roof construction began with finding a suitable form for the roof arch. Fortunately, I had a round metal tray of an appropriate size. I cut a series of roof formers in foam-core. I glued these to a foam-core base—a sub-roof. I used one of the rounded formers and more foam core to duplicate the end geometry. I wanted something to experiment with for the roof ends. I installed longitudinal roof formers between the arches. I also laminated wood beams to the underside of the sub-roof to keep it flat.

I glued a sheet of cardstock to my trial end piece using rubber cement. After this set, I trimmed the cardstock to fit the edges of the end former. I then removed the cardstock from the former to use it as a template for the final roof pieces. The resulting template has a gentle arch to fit the roof arch and side sections that edge outward to meet that gentle arch.

I used the roof end template to layout cut lines on the roof cardstock (chipboard). I left quarter-inch margins outside my template for subsequent trimming. This turned out to be perfect! I cut the gentle arch freehand, as I no longer had a hard device to use for a cutting guide. I accounted for this with my roof former design and my ultimate plan to cover the roof joints with paper strips.
I glued the end roof sections to the roof structure using both carpenter’s glue and gap-filling CA glue. I then placed wood pieces as weights to hold the roof panels in place on the former. I did a small amount of trimming of the end roof sections where they overhung the arch roof former. I then added a second arch roof former inside the end formers to support the center roof panel edges. The center roof section was applied, once again aided by heavy wood pieces on the top and edges to hold everything in place as the glues set. Finally, I cut the roof along the diagonal back roof former.

Several coats of paint were applied to the chipboard roof panels as they soaked up a lot of paint. I was pleasantly surprised to find my guestimates of extra margins around the roof were perfect for my needs. The sub-roof neatly fit into the wall assembly. The freight docks and stairs were built from scrap-box styrene pieces, and painted to match the structure.
