The project was a NYSDOT contract to perform drainage improvement and highway reconstruction on Veterans Memorial Highway between Lincoln Avenue and Grundy Avenue in the Town of Islip, NY. The project included the installation of 85 new drainage structures and 6,600 LF of drainage piping. The project scope also included the installation of new watermain. The existing pavement along the curblines and median was reconstructed with new pavement, concrete curbs and sidewalk to faciltate the utility construction. The existing recharge basin was also regraded and planted to accommodate the drainage improvements.
WHAT MADE THIS JOB COMPLEX
As part of this project, in parallel to Posillico performing drainage and highway reconstruction, local public utility companies, including National Grid, Long Island Power Authority, and Verizon, were to perform simultaneous relocations and replacements of their respective infrastructure with their own forces, marrying Posillico’s schedule with that of the utility companies. There was no contractual relationship between Posillico and the utility companies, however there were dependencies between Posillico’s schedule and the utility company schedules, where certain utility work required completion in order to progress Posillico’s project. This, along with seasonal utility work moratoriums, directly impacted and complicated the project schedule.
HOW POSILLICO SOLVED IT
In order to develop and maintain the project schedule, test pitting was performed early on in the schedule, and all conflicts and inconsistencies in the plan were identified. Posillico worked intimately with the NYSDOT and the local utility companies to develop plans and redesigns to address and mitigate the conflicts and inconsistencies. Posillico also re-sequenced the project schedule in order to facilitate the various utility company schedules and performance issues.
