The aim of this program was to improve project delivery and reduce costs by streamlining projects using the Design-Build project delivery system. Posillico teamed with Greenman-Pedersen, Inc. to carry out the project design work and L.K. McLean Associates, P.C. to perform professional engineering inspection on the project. By utilizing the Design-Build project delivery system, the design, construction, and inspection work was performed under a contract with one entity. This allowed design and construction to progress together reducing the overall timeframe as compared to conventional Design-Bid-Build delivery methods.


The owner NYSDOT required that this project be completed in a very short time frame. Coupled with the fact that this was the first Design-Build project that NYSDOT had ever let in the Long Island region, Posillico had many challenges to face in order to complete the project on time. By procuring the project as a Design-Build, Posillico took on not only building the project, but also guiding the design to meet the demands of the project. Furthermore, the logistics of the project were also elaborate due to the distance between each of the project structures, which spanned from the NYC border to the middle of Suffolk County.


Posillico solved these problems by carefully preparing and project CPM that included both design and construction activities. The CPM was then successfully executed through continuous communication with all project team members including NYSDOT and their QA design consultant. This included weekly design review meetings, the use of collaborative file sharing software, and weekly construction coordination meetings. Project resources also had to be carefully planned out to ensure project completion in a timely manner.
