Conveyance (Elevator) Licensing Program

Category 5 (CAT5) Witness Testing

Witness testing is performed with a rated load and speed every five years from installation. The test is a requirement per Colorado State Law on a hydraulic elevator if the elevator is equipped with car safeties, a plunger gripper, a governor, an oil buffer, or an over-speed valve.

The Certificate of Operation Process:

* Compliance Month (or as otherwise approved by Greenwood Village)

(Greenwood Village, Colorado Department of Labor & Employment, Oil & Public Safety - Conveyance Program, 01/01/2020. 7 CCR 1101-8)

Certificates of Operation:

Once the inspection invoice has been paid, your Certificate of Operation will be sent to you. The Certificate of Operation will be issued and valid for one year from the date of issue (payment of fees).

Should any correction items be noted on the previously performed inspection report, a 90-day Temporary Certificate of Operation (TCO) will be issued. Once written notification is received that all correction items have been resolved, a new Certificate of Operation will be issued for the remainder of the year.

Without a Valid Certificate of Operation, the state does not consider the elevator compliant and will be locked out of service.

To update your contact information, please send us an email to elevators@greenwoodvillage.com. Be sure to reference the Ownership entity, property manager, and property address.

Conveyance Inspections:

Annual Inspections are conducted by Professional Elevator Inspection (PEI), our 3rd party State-certified city contractor. PEI will contact you directly to schedule the inspection and provide you with an inspection report via email upon completion. If the report indicates correction items, please coordinate the necessary repairs with your elevator maintenance company.

5-Year Witnessed Safety Tests and inspections are the responsibility of the Property Owner/Manager. These must be coordinated with your elevator service company and PEI. The date of the last five-year inspection is listed on the Certificate of Operation for your elevator.

To schedule an inspection, email PEI with your request.

Invoicing:

You will receive an email for each elevator to your owned/managed building contact on record approximately 30 days before the Certificate of Operation for your elevator(s) expires. Should the 5-Year Witnessed Safety Test be required, you will receive an invoice for the year it is due to be performed.

Payment:

Credit/Debit Card Payments may be made by accessing our Online Access Portal

Checks must be made payable to the City of Greenwood Village

Elevator specifications outline the technical and structural requirements for an elevator system's installation, operation, and safety. These specifications ensure the elevator is functional, reliable, safe, and compliant with local codes and regulations. If applicable, the general specifications might include:

Type and Capacity:

• Classification of the elevator (passenger, service, residential, etc.).
• Load capacity (maximum weight capacity).
• Speed (usually in feet per minute or meters per second).

Dimensions:

• Car dimensions (width, depth, and height of the interior).
• Door size and type (e.g., side slide, center opening).
• Hoistway dimensions, including overhead clearance and pit depth.
• Machine room dimensions, if applicable (some modern elevators are machine-room-less).

System Components:

• Type of drive system (hydraulic, traction, machine-room-less, etc.).
• Controller specifications (the electronic system that operates the elevator's movements).
• Details about the motor, including power requirements.
• Safety system components (e.g., brakes, emergency backup systems).

Electrical Requirements:

• Power supply needs (voltage, phase, frequency).
• Information on necessary disconnects, fuses, and wiring.
• Battery backup systems or emergency power options.

Safety Features:

• Emergency communication systems (phones or intercoms).
• Safety sensors (door obstruction sensors, overload sensors, etc.).
• Fire emergency operations like Phase I and Phase II operations as per fire codes.
• Escape hatches and access for emergency personnel.
• Compliance with seismic codes, if applicable.

Interior Finishes and Materials:

• Wall panels, flooring, ceiling materials, and lighting fixtures.
• Handrails, mirrors, control panel materials, and button designs.
• Any ADA (Americans with Disabilities Act) requirements, like Braille on the buttons or audible signals.

Performance Features:

• Ride comfort factors (acceleration, deceleration, vibration, noise, etc.).
• Operating features such as signal fixtures, hall calls, and floor indicators.
• Ventilation or air conditioning systems within the car.
• Codes and Standards Compliance:

Adherence to local building codes.

• Compliance with safety standards governed by the American Society of Mechanical Engineers (ASME) or equivalent.
• Fire safety standards adherence.

Drawings and Diagrams:

• Detailed drawings of the elevator car, hoistway, and machine room (if applicable).
• Electrical diagrams, including connections between components.
• Site preparation and installation details.

The specifications are typically part of a more extensive set of construction documents and must be adhered to during the installation to ensure the safety and functionality of the elevator. During inspection, these documents are also critical to verify that the installation meets the outlined specifications and applicable codes.
