3) Performance Requirements: It is the intention of this specification that elevator equipment be maintained so as to preserve the operating characteristics in line with the original design.

Should designated authority find through his own investigation or that of his representatives that these standards are not being maintain, the Contractor shall be given twenty-four (24) hours’ notice to restore the performance to the required level. Failure by the Contractor to restore the performance to the required level within a forty-eight (48) hour period shall constitute sufficient cause for termination of the contract by reason of default, at the option of BCHA.

The following performance levels of the original design shall be maintained at all times:

a) Contact speed of all elevators, dumbwaiters and escalators shall be maintained, and brake to brake flight times shall be maintained as originally installed.

b) Leveling accuracy of all elevators shall be maintained at all times.

c) Opening and closing times of all hoistway and car doors shall be maintained within limits of ANSI A17.1, ANSI A17.1 - 1981, ANSI A17.1a - 1981, ANSI/ASME A17.1 - 1981 codes, yet assuring minimum standing time at each floor.
