Project Description

Helping to Build the LaGuardia East End Substation

Port Authority

The Challenge

The Port Authority of New York and New Jersey is a self-supported interstate organization between the states of New York and New Jersey that oversees most of the regional transportation infrastructure for the New York City metro area. The Port Authority was invested in establishing a BIM-based construction process for their East End Substation project, one of the two major subprojects comprising their LaGuardia Airport Redevelopment Program. T. Moriarty & Son, the acting general contractor for the project, engaged Microdesk to leverage their expertise to help fulfill the BIM requirements set out by the Port Authority. The goal was to implement a full BIM and Virtual Design and Construction (VDC) based process that would include design, MEP coordination, laser scanning, 4D scheduling, visualization, cost loading, and as-built modeling. The overall objective was to develop fully integrated, data rich building models that could later be leveraged for facility asset management.

Solution

Microdesk’s first step was to create a BIM execution plan that outlined how communication and project delivery processes would be facilitated by the owner, contractors, and subcontractors. Microdesk assumed responsibility for the model-based coordination process with the MEP subcontractors, which was to be performed entirely within Revit to LOD 400. Throughout the duration of the project, Microdesk also maintained a 4D Navisworks model tied to the latest cost-loaded Primavera schedule, which provided a visual representation of project construction progress. Upon completion of construction, Microdesk updated the BIM models to represent as-built conditions from laser-generated 3D point clouds. The models also incorporated construction and asset data for future migration into the Port Authority’s asset management system.

Aside from managing the BIM process, Microdesk created custom training classes for contractors to ensure that all parties involved were technically aligned on the project in order to maintain efficiency. This further enabled teams to gain proficiency with BIM technologies, which not only reduced costs for this project, but will enable efficiencies on future projects as well.

Results

By helping The Port Authority and their contractors to attain a better understanding of BIM tools and processes, they were able to significantly reduce the project delivery time for the East End Substation project, as well as implement a more cohesive process that will be applicable for future projects and modeling initiatives. After construction, the Port Authority possessed an accurate, data-rich model for inclusion into the asset management system, and with it the capability to use the model for future design and facilities management projects.
