Green Streets Northeast Package (Phase I)

The Philadelphia Water Department (PWD) employed green stormwater techniques to reduce runoff volume in order to reduce combined sewer overflow (CSO) discharges. These projects are related to the city-wide GreenWorks Philadelphia plan proposed in 2009. As part of these efforts, R2T assisted CH2M Hill with the following tasks related to multiple stormwater trenches within PWD’s “Green Street” efforts: Multi-Stage project design development, AutoCAD drawings preparation,  preparation of Class 4 Construction Cost Estimates (CCE), as defined by the Association for the Advancement of Cost Engineering Practice No. 18R-97,  and utility location and data entry for the PWD’s Guaranteed Pavement Information System (GPIS). R2T also assisted with design deliverables as well as the preparation of design drawings in AutoCAD.

The CCE was performed utilizing conceptual plans from which R2T identified all line items and forming construction costs. Example line items included associated piping, excavation, saw cutting, asphalt paving, concrete curbs, sidewalks, inlets, fill material, tree planting, debris disposal, traffic control, PVC cleanouts and associated stormwater fittings. Furthermore, R2T assisted with design development, line item estimation, data entry, and estimation reporting.
