The industrial buildings, surveyed

ARC-4 DUG · ASSEMBLED FROM THE RECORDS THIS WAVE READ

The checklist asks for the town's industrial buildings as a survey; the wave's reads supply four structures across a century, and the survey prints them in order. First, the grain elevator of Howard's 1907 street — "a grain elevator of ample capacity," company-owned — the vertical landmark of the depot village, standing at the crossing of the three railroads whose junction made the town. Second, the Central Cut Glass works of 1910, the survey's best-documented industrial building: two stories, 30 by 200 feet, 12,000 square feet, built of "the best made fire proof cement blocks" — the period's industrial material of choice, cast stone as fireproofing — with a fifty-foot stack, fifty cutting frames, and a plant of boiler, engine, and dynamo itemized in the arts addendum; gutted by fire on February 19, 1919, its bare walls the survey's one ruin, never rebuilt and not standing in any modern record. Third, the Plas/Steel expansion of 1973: a roughly $500,000 plant project in the town's industrial park, financed through revenue bonds, of which the South Bend commission's file is the surviving description — the building's form unrecorded in the sources reached, its cost and purpose on the record. Fourth, the Polygon plant on Industrial Park Drive (103 Industrial Park Drive in the directory record), the survey's living term: a working pultrusion and machining complex whose August 2026 expansion — Swiss CNC, pultrusion, advanced inspection — is the industrial park's current building news. The survey's gaps print with it: the depots' architecture stands for the Sanborn run (DF-W-69, with GAP-W-TRN-4), and the pickle works' and door plant's buildings stand in the businesses record at the strength that leg reached.
