HRSD, as part of their wet weather Consent Decree, is going to execute a $1 billion program to reduce infiltration and inflow (I/I) in the collection system. This pilot was developed to test the design-build approach to deliver rehabilitation work aimed at getting I/I out of the system. This project produced important lessons learned in terms of RFP requirements, payment structure, technical specifications, negotiations and addressing challenges during construction.
