The ability to convert photographs into CAD models made it possible to repair an induction furnace fume collection ductwork system with one shutdown rather than two, preventing several hours of additional down time.
DeChant Consulting Services, Inc., (DCS) is a five-year old company that specializes in close-range photogrammetry to support industrial projects. Clients include process plant owners, construction contractors, consulting engineers, and municipalities. The firm's principals have a combined twenty years of experience with photogrammetric measurement techniques, surveying and conventional measurements. Advances in computer technology, and photogrammetric modeling software in particular led them to found the company and bring these benefits to industry.
Retained by Industra Service Corporation in January 1998, DCS was hired to provide close-range photogrammetric services at a facility owned by American Silicon in Wenatchee, WA. A badly deteriorated system of induction furnace ductwork required replacement to sustain plant operations. The challenge was to minimize the duration of the furnace shutdown while retrofitting it with new ductwork. This could only be accomplished by prefabricating the replacement ductwork and readying the fabrications for an intense construction effort during shutdown of the furnace.
