Dvirka and Bartilucci Consulting Engineers (D&B) provides its clients with collection analyses and contracting services for residential and commercial refuse, recyclables and compostable materials. D&B staff have carried out numerous assignments to provide collection economics analyses, routing efficiency, equipment alternatives, billing methods, bidding, contracting and privatization assessments.

D&B has developed a Collection Cost Model as part of its comprehensive Solid Waste Management Planning Decision Model. The Collection Cost Model is capable of evaluating the economics of current practices in comparison with alternatives. The parameters accounted for in the model include the number and density of collection locations; vehicle capacities and compaction cycle times; time per stop; off-route time; fleet size; crew size; and labor costs.

D&B has evaluated the efficiency of collection equipment based upon capacities, labor requirements, automated loading options, multiple compartments (refuse, recyclables) and on-board compaction of recyclables. The firm conducts equipment demonstrations, recommends equipment, prepares specifications and conducts procurement bidding.

Our clients have asked us to advise them on the benefits of private versus public collection. In these assignments, D&B staff have prepared economic models of private and public collection alternatives, using key parameters, such as crew size, labor rates, equipment capacities, routing and profit margins, to estimate the costs of the options.

D&B has also drafted collection ordinances and regulations establishing set-out requirements for refuse, recyclables and landscaping wastes; weight and content restrictions; and collection districts within municipal boundaries.
