Resurface Wraps refinished the elevator car interiors, walls, columns, panels and doors at DHL's office building in Plantation, Florida in a single light oak architectural film, saving $190,000 and 6 to 7 months against replacement, with no closure and no loss of building operation. The full account of how that job was sequenced, what the elevator code required of the cab finish, and where the numbers came from, is in the DHL Plantation case study. That figure is this building's, measured against this building's replacement scope. There is no published independent benchmark comparing elevator cab interior replacement with refinishing, and a genuine comparison for another building has to be scoped rather than scaled from square footage.

An office building has no version of a room out of inventory. A hotel can block ten rooms and sell the rest; a store can work a fixture run overnight. An office has a fixed population that arrives inside the same 45 minutes every weekday and expects the elevators, the corridors and the conference rooms it booked to work. Everything about a corporate program is built around that.
The elevator bank is where it bites first. Taking one car out of a bank of four costs the building a quarter of its handling capacity and lengthens the up peak interval by at least a third. The standard up peak method defines the interval as round trip time divided by the number of cars, and the real degradation is worse than the ratio suggests, because the remaining cars run fuller and slower. A three car bank loses a third of its capacity. That is why cab work is sequenced one car at a time and why the length of the window matters more than the unit price.
The second difference is that a corporate interior is judged on the surface that was left out. A refinished lobby leading to an original elevator cab, or refreshed corridors ending at fifteen year old doors, tells every visitor precisely how far the budget went. Matching one finish across gypsum columns, hollow metal doors, millwork panels and cab walls is five different prep problems producing one appearance, and it is the part of the work that decides whether a program reads as a renovation or a patch.
Elevator car interiors are governed by ASME A17.1 rather than by a general Class A rule. A17.1 requires materials exposed to the car interior to be metal or to have a flame spread rating of 0 to 75 and a smoke development rating of 0 to 450 under ASTM E84, UL 723, NFPA 255 or CAN/ULC-S102.2, a band that spans both Class A and Class B. A given authority having jurisdiction or elevator contractor can still require Class A, so confirm before ordering. Cab floors are governed by a separate flooring test, ASTM E648, and architectural film is not a flooring product, so floors sit outside a film scope.
Interior wall and ceiling finish elsewhere in a Group B office building is a different question with a different answer, set by the building code by location: interior exit stairways and exit passageways, corridors, and rooms and enclosed spaces each carry their own class, and the requirement relaxes where the building is sprinklered. Section numbering has moved between code editions, so the class that applies to a specific corridor is the one in the edition your authority having jurisdiction has adopted. We confirm that with the AHJ, along with the current manufacturer data sheet for the specific product, before anything is specified. Our explanation of what Class A fire rated means under ASTM E84 covers the interior finish side in full.
One thing the codes do not do is authorize film on a labeled fire door by default. A rated opening is covered by a specific listing for a specific door construction under stated conditions, or it does not receive film, which is set out in the Best Western Spokane door program.
