CORNING | A multi-million dollar project to fully renovate Corning Inc.’s former headquarters, known as C Building, is continuing on schedule.

The most obvious work being done currently is a complete replacement of the Pulteney Street building’s exterior using new materials.

“The final design of the exterior will replicate the previous appearance with new technology,” company spokesman Joseph Dunning told The Leader.

That new technology will include electrochromic glass, a “smart” glass that can change its tint based on conditions, saving on both lighting and climate control expenses.

The exterior revamp is expected to be completed by the end of this year.

Interior renovations will bring the nine-story office building’s layout in line with the company’s modern corporate culture, including new walls, carpet, tile, ceilings, furniture and lighting. The layout is expected to include a combination of traditional walled offices, cubicles, shared collaboration spaces and meeting areas, Dunning said.

It will also include new mechanical, electrical and plumbing systems in keeping with modern practices and current energy, fire and building codes.

Interior demolition work to make that possible will also be extensive, meaning those renovations aren’t expected to be completed until the latter part of 2020.

The Steuben County IDA in late 2018 approved a $2 million sales tax exemption for the project based on an estimated investment of $25 million and the retention of 200 jobs.

Corning Inc. officials have said they are not disclosing the cost of the renovations.

The building now known as C Building was constructed in 1955 as the headquarters of what was then Corning Glass Works.
