DEPARTMENT OF PUBLIC WORKS: STAGGERED COLLECTION SHIFTS

12-A
DEPARTMENT OF PUBLIC WORKS: STAGGERED COLLECTION SHIFTS
Problem Identification:
Presently, all City collection yards begin collection activities at the same time. This schedule results in a huge volume of full collection vehicles arriving at BRESCO for disposal at essentially the same time. Self’generated truck lines result in inefficiencies, delays, and unnecessary overtime by the department.

Recommended Action:
Stagger starting schedules to “smooth out” the arrival times of City collection crews at BRESCO thereby increasing collection efficiencies by minimizing wait times.

Classification:
Cost Savings

Functional/Operational Area:
Bureau of Solid Waste

Estimated Annual Impact:
$150,000

Estimated Implementation Costs:
None

Barriers to Implementation:
Resistance to changes in shift start times by collection personnel and concern about reduced overtime earnings can be expected. Also, there appears to be existing labor contact terms that may prevent implementation of this recommendation.

Projected Implementation:
60 – 90 days

Next Steps:
Perform a time study of each collection yard to determine the time required for an average collection route to perform one complete cycle from the collection yard through the route and finally to BRESCO. Develop a model that optimizes the start time for each yard and results in minimal predictable truck traffic impact at BRESCO. Meet with collection supervision and implement the change in start times after holding informational meetings with all impacted employees.

Analysis:
Under current practices, the City’s collection crews embark on their daily routes at approximately the same time, leading to concentrated arrivals of collection crews at BRESCO. The inability of collection crews to rapidly enter and exit BRESCO contributes to the high level of overtime costs incurred by collection crews. The estimated financial impact of $150,000 is based on achieving a modest 10 percent reduction in overtime costs.
