EXHIBIT A – SCOPE OF WORK
SCOPE OF WORK – SNOW REMOVAL SERVICES:
The contractor will provide snow removal services at various City locations, excluding Denver
International Airport.
The contractor shall furnish all labor, equipment, and material as necessary to perform all specified services.
The contractor is required to provide to the General Services Contracts Office a centralized point of delivery for all contract related communication to include but not limited to work order assignments, invoicing, annual insurance renewals, and general contract communication.
For a complete list of snow removal locations, refer to Exhibit A – Attachment A – Snow Removal
Locations. Contractor must prioritize snow removal services at locations identified as “Priority 1” such as police districts and other locations open prior to 7:00 A.M.
1. The Contractor shall provide snow removal, de-icing, and melting/traction agent application services, including all labor, supervision, equipment and all fuel, lubricants, vital fluids, parts, maintenance repairs, and all items of cost needed to provide these services, covered by the resulting agreement which the City may require during the term of the agreement.
2. Snow removal shall consist of pushing all snow off the surfaces of designated areas. Application of melting or traction agents shall involve the even distribution of those agents across the same surfaces being plowed.
3. If snow fall occurs during non-standard work hours (Monday through Friday 5:00 PM to 7:00
AM, weekends, and City holidays), best efforts will be made to remove snow prior to the office opening for the next business day (standard work hours are Monday through Friday 7:00 AM to
5:00 PM) based on total accumulation. The Contractor shall have all areas cleared in time for the
Facility to open on the next regular business day.
a. Several City buildings operate on a 24/7/365 schedule. These buildings require that snow accumulation greater than 1” be removed as soon as possible. These buildings include but are not limited to:
• Police Administration Building
• Police Districts
• Denver Animal Shelter
• Police Academy
• Van-Cise Detention Center and Lindsey Flannigan Justice Center
4. Areas to be cleared may include all parking and sidewalk areas. Contractor is required to respond within two (2) hours of dispatch if one inch (1”) or more of snow accumulates but may be called in before one inch (1”) accumulates. It may be necessary to shovel between cars in lots and use a manual spreader to de-ice tight spaces without damaging vehicles or getting ice melt on cars.
Drift-ins and continuous snowfalls will be serviced as much as possible to keep these areas clear.
In some cases, it may be necessary to wait until it stops snowing before the area can be cleared.
5. In cases of repeated heavy snowfalls, the City may request that snow piles be removed off-site to a City designated location. The removal of the snow piles will be at the request of the City and not required on every plowing occasion.
6. The Contractor will take all possible precautions to protect people from injury and create as little disturbance and inconvenience as possible.
7. Police Precincts – Contractor shall not leave snow drifts in such a manner as to block access for police vehicles to exit parking spaces. Snow drift behind cars must be shoveled out to allow for easy exit.
8. Police Academy Driving Track – Contractor is responsible for coordinating with DPD
OPS Support the dates in which the Contractor will be required to perform snow removal services for the driving track. DPD OPS Support will provide these dates on the first day of each month for the following month.
9. Damage caused to buildings, posts, fences, automobiles or any other such readily visible objects will be repaired as soon as practical at the Contractors expense. In the event repairs are not made within seven (7) business days, the City will have the right to have repairs made or to make repairs and deduct this amount from any invoices due to the Contractor.
10. Regarding the use of deicer products both liquid and solid ice-melting salt and salt sand mixtures: contractor will apply materials evenly and per the application rate recommended by the manufacturer, or per industry best practices. Contractor must avoid waste due to over application, or un-even or careless application resulting in clumps of deicer in some spots, and insufficient deicer in other spots. No deicer salt or chemicals should be applied directly onto metal: avoid application of deicer to the foot of flagpoles, bicycle stands, fire hydrants, parking meters, benches, etc., and anything bolted to pavement- keep a 6-inch-wide space or buffer between metal objects and pavement treated with deicer. Deicer must be applied in a manner that prevents runoff into storm drains.
11. A snow removal plan is required to be submitted annually to the GS Operations Supervisor and/or Facility Superintendent before the snow season and discussed in the annual pre-season meeting. The snow plan shall include detailed information on the following:
a. Site-specific maps for each service location to include snow piling, plow areas, hand shoveling areas.
b. How the contractor plans to service simultaneous service locations listed in “Section 4” to adequately prepare and maintain locations free of snow and ice accumulation.
c. Detailed information on anti-icing and de-icing services and equipment that will be used and stored.
d. Detailed information on the snow removal equipment proposed to be used.
e. Detailed plan on manpower dedicated to snow removal operations to service multiple locations simultaneously and consecutively.
f. The snow plan must be cognizant of the 24/7/365 operation of applicable facilities.
g. Detailed information on how the contractor will conduct quality control during snow or ice events and effectively monitor weather conditions during snow call outs.
h. The snow removal plan shall include the development of a “snow activity” log. Which will include the following minimum information:
i. Location
ii. Condition of site
iii. Actions taken
iv. Equipment and Personnel Requirements
v. Arrival time on site
vi. Departure time
12. Check-ins and Check-outs required for each site along with before and after pictures for each site, including time stamp, must be emailed to the Facilities inbox at
SnowNotifications@denvergov.org. If snow removal overlaps with normal hours and the Facility
Maintenance team starts to clear snow at the site, the contractor must check in with Building
Superintendent/ Multiple Trades Supervisor to confirm if support is still needed.
PROPERTY DAMAGE:
Contractor is required to report all occurrences of property damage and supporting pictures within
72 hours to SnowNotifications@denvergov.org. Contractor is liable for all occurrences of property damage. If contractor cannot address the repair, the City will address the repair and will be reimbursed by the contractor at cost.
LIQUIDATED DAMAGES:
If the contractor fails to deliver the supplies or perform the services within the time specified in their contract, or any extension thereof, the actual damages to the City for the delay may be difficult or impossible to determine. Therefore, in lieu of actual damages, the contractor shall pay to the City as fixed, agreed and liquidated damages for each calendar day of delay, the amount of $100 per day. The City may terminate this contract in whole or in part as provided in the "Default" provision.
In that event, the contractor shall be liable for such liquidated damages accruing until such time as the City may reasonably obtain delivery or performance of similar supplies and services. The contractor shall not be charged with liquidated damages when the delay arises out of causes beyond the control and without the fault or negligence of the contractor.
SPECIAL CONSIDERATIONS:
BACKGROUND CHECKS:
Contractor, at its expense, must conduct a background check for each of its employees, as well as for the employees of its subcontractors, who will provide services to the City. The term
“employee” for the purpose of this requirement, includes anyone who is providing services for the City under this Contract. Background checks are to be conducted through an independent background check vendor and must include the following:
• Social Security Number Trace;
• Federal Criminal Records (includes wants, warrants, arrests, convictions, and incarcerations);
• Colorado Criminal Records (includes wants, warrants, arrests, convictions, and incarcerations);
• Criminal Records from other States if the employee disclosed, or the background check identifies, that the employee lived in another state in the last seven years
(includes wants, warrants, arrests, convictions, and incarcerations); and
• National Sexual Offender Registry Search.
mailto:SnowNotifications@denvergov.org mailto:SnowNotifications@denvergov.org
The background check shall include all convictions for the last seven years and may include additional convictions beyond seven years when permitted and/or required by law.
Because of the sensitive nature of the work locations proposed within this solicitation, the
City shall automatically disqualify from employment under this contract persons with felony convictions. Alternatively, the City may require that a fidelity bond, or such other assurance in such amount as deemed appropriate, be provided to the City as a condition precedent to grant permission where an employee’s prior conviction would otherwise preclude their participation under the contract.
All Contractor employees are required to self-disclose to the Contractor any criminal charges and convictions and nolo contendere pleas (not contest pleas) that occur while providing services to the City within three business days of the conviction, charge, or plea. Contractor is required to inform the City of any criminal charges or convictions or nolo contendere pleas
(no contest pleas) that arise while an employee is on assignment with the City. Contractor must inform the City within one business day of the Contractor having knowledge of the charge, conviction, or plea. The City will determine, in its sole discretion, whether the employee will remain on a
City assignment.
The background check(s) must be conducted successfully prior to initial access and/or involvement by employees. Employees who separate from the Contractor’s employment must undergo another background check prior to renewed access and/or involvement in providing services to the City. The City also has the ability to audit the Contractor’s background check process, to ensure compliance with City standards, at any time.
In addition to the foregoing background check, certain City locations require employees to pass a Federal CJIS background check. These background checks will be administered by
CBI – Colorado Bureau of Information. Vendors will need to be part of the CBI Vendor
Management Program. Contractors will be provided entrance cards for each facility.
Contractors are not allowed to share cards to provide services.
The following locations require Federal CJIS background checks:
• All Police Facilities
• All DSD Facilities
• Police Academy
• Denver Animal Shelter
• Traffic Operations
• DPD Police Precincts
• Denver Human Services
All work to be completed under this on-call contract will require that each person working on- site at a Denver Police Facility, City Attorney, Denver 911, Denver DA, and all other secure facilities within the City and County of Denver that has CJIS information, including all sub- contractors, to have completed CJIS Security Awareness Training. The CJIS Security
Policy written and maintained by the Federal Bureau of Investigation is the standard by which all criminal justice agencies nationwide must protect the sensitive data they possess and share with authorized entities. The policy outlines requirements such as personnel security, training, encryption, physical security, media protection, access control, construction, and more. The CBI CJIS Vendor Management Program is designed to help vendors and criminal justice agencies achieve and maintain compliance more easily by providing an easier fingerprinting/vetting process, assisting with the required training, sharing audit findings, and offering resources for questions about CJIS security.
All Denver law enforcement is now requiring that the Federal CJIS background check be completed to work at any site connected to law enforcement for the City and County of
Denver.
The CJIS background check can be completed through the CBI – Vendor Management Program as a
CJIS Support
