Croton Water Treatment Plant


This $2 billion project is a 290 mgd facility to treat New York City’s Croton water supply. The treatment process consists of dissolved air flotation; ozonation; and high-rate deep-bed monomedium filtration.

PMA developed schedules for three alternative sites: Mosholu, Eastview, and Harlem River. PMA reviewed all project documentation, including design drawings, specifications, estimates and preliminary schedules, environmental-impact statements, the consent decree, and other miscellaneous documents.

PMA met with the project team and collaboratively determined duration and schedule logic. PMA configured Primavera P3 activity and project codes to allow summarization of the schedule to various levels while still showing the interfaces between several contracts on the project site.
