These measured resistance values shall be recorded at the time of installation.

Operational Check The contractor shall develop a checklist and submit for Contracting Officer approval. The checklist shall be partially comprised of all operations/features available with the existing elevator and any new features provided by the new controller. The checklist may be used during the 30 minute period of elevator operation described in Test Period Above.

The contractor shall furnish and install any lamps that may be required ensure all lamps installed are working.

Over-speed Test The testing shall include that test required to verify proper operation of the existing car over-speed sensor (governor). The sensor is set to decelerate the car when the speed of the car reaches between 20% to 40% more of the rated car travel speed. The Government will be responsible for costs associated with any adjustments or repair required should the governor fail the test. The test shall determine the car speed at which the switch contact opens the circuit to de-energize the controller upon overspeed. The test shall demonstrate that the contact does indeed cause de-energization of the hoist motor. The test shall also demonstrate that the force required to “set” the “overspeed brakes” on the elevator car is within acceptable limits with regard to the tensile strength of the rope and working limits of the equipment to which it is connected.

Warranty The Contractor shall provide a warranty for the work described herein. The warranty shall cover the equipment furnished herein and shall provide for all parts and labor required to maintain the system in operation.

Shop Drawings The Point of Contact for shop drawing submittals will be provided after contract award.

The Contractor shall prepare and submit for approval 3 copies of all shop drawings as called for under the various sections of these specifications. These drawings shall be complete and detailed.

With each submittal of shop drawings, the Contractor shall certify that he has reviewed the shop drawings in detail and that they are correct and in strict conformance with the contract drawings and specifications except as otherwise explicitly stated. Upon completion of review by the Contracting Officer, if approved, each copy of the drawings will be identified as having received such approval by being so stamped and dated. The Contractor shall make any corrections required. If the Contractor considers any correction indicated to constitute a change to the contract specifications, notice as required under the contract clause, "Changes" shall be given to the Contracting Officer. Two sets of all shop drawings will be retained by the Contracting Officer and one set will be returned to the Contractor. The approval of the drawings shall not be construed as a complete check, but will indicate only that the general method of construction and detailing is satisfactory. Approval of such drawings will not relieve the Contractor of the responsibility for any error which may exist as the Contractor shall be responsible for the dimensions and design of adequate connections, details, and satisfactory construction of all work.
