Durham Public Works Mission

Public Works provides a wide range of services, including street maintenance, engineering design, development review and stormwater quality and infrastructure maintenance.

The Department ensures that the street infrastructure is safe and well maintained, which supports the quality of life and serves as a foundation of a healthy economy. As guided by the City’s Strategic Plan, Public Works serves as a steward of the City’s physical assets and ensures that residents live in a safe, secure and thriving community.

Durham Public Works Goals and Objectives

• Communicate clearly to citizens

• Evaluate projects against mission: – Effectiveness

– Efficiency

– Equitable provision of services

• Visualize commitment to each City district – Expenditure

– Progress of work

Integration Goals

• Accurate schedule and cost information – Timely

– Aggregated across geographic areas

• Inform citizens of work in advance

• UI efficiency – Enable fine-grained project control

– Eliminate duplicate entry

– Avoid the “See Attached Spreadsheet” problem

• Do more with less

How we did it: Software Systems

• Fine-grained progress reporting: “Primavera Daily Report Extender” (PDRX) web-based workflow tool – Actual dates of work

– Unit quantities vs. contract for every GIS location

• Progress payments: Primavera Contract Manager

• Planned & actual schedules: Primavera P6

• City accounting: MUNIS

• GIS, citizen communications: ArcGIS

How we did it: Integration Technologies

• Contract Manager: via XML API – .NET wrapper layer to facilitate programmability

– PDRX: Subsidiary (detail) ledger to PCM

– PCM data is aggregated across GIS locations

• P6: via P6 Web Services – Conventions for relationship between WBS and

GIS activities

• ArcGIS: via database access – Updates to well-defined layer data

Futures

• Predictive model for repaving costs

– Use GIS attributes with project history

• Feedback loops for estimating process

– Use historical bid prices and project actuals

• Geographic optimization of dissimilar work

Bid price distribution

Lessons Learned

• Multiple constituencies = Divergent needs

– Contractors: Task and location focus; UI efficiency

– Inspectors: WIP and outstanding tasks

– PMs: Schedule and cost controls

– Citizens: Just tell me when you’ll be done

• Integrated systems let us serve each constituency well

Lessons Learned

• Data cleansing is essential

– Common database of bid items

– Common keys

– Avoid text matching if you can

• PCM XML API quirks

– Pleased to see PCM WS API

• Define usage and data models before integrating
