World Trade Center Tower One - Port Authority of New York & New Jersey

New York, NY

Ellana provided cost estimating and project cost control services for the 2.6 million-sf, 105-story LEED® Silver certified tower. Services include assisting the project program manager with independent estimate preparation for trade bid packages; bid reviews; estimate preparation for bulletins, addenda, and change orders; and tracking and updating budget costs.

There were challenges for everyone involved in the reconstruction of the WTC site. The inherent sensitive nature of the site, the complexity of multiple buildings and structures, private and public stakeholders and budget constraints, extremely complicated level of coordination, presented an unprecedented, but ultimately successful, challenge for our team in preparing myriad estimates, pricing an enormous amount of design options, putting bid packages together based upon the specific requirements of each individual scope, verifying estimates at each design milestone, leveling contractors’ bids, and finally preparing change order estimates as well as negotiating them with the contractors on behalf of our clients.
