IPD project saves client $1.5MM

Providing engineering & design as part of the Integrated Project Delivery team for global financial client

TAI provided the mechanical, electrical and structural engineering design for the complete renovation of building 1 and 2 which combined was approximately 220,000 SF in total. Between the two buildings, the following tasks were executed:

• 16 air handling units where replaced with eight new efficiency units: four 90-ton high efficiency, two 105-ton high efficiency, and two 70-ton efficiency units.
• Approximately 380 new fan-powered terminal units were replaced with careful coordination to ensure spaces were quiet.

For Building 1, TAI provided design for the following so there was minimal downtime during the renovation:

• 9-ton of cooling (N+1) for critical rooms and A/V closets utilizing modular air-cooled chillers.
• Critical loads included a Network Distribution Center with approximately 30-racks, a Network Lab, and 9 IDF rooms.
• Computer room air conditioning units with hot aisle / cold aisle separations were utilized for IDF rooms.
• Specially designed credenzas were used for cooling A/V equipment with fan-coil units.

For Building 2, an operations center required 24/7 operation, and the air handling units were designed so that smaller unit could operate at part load. Nine IDF rooms and A/V closets were provided with chilled water fan-coil units utilizing chilled water from the adjacent building. This project obtained LEED Silver.The project team utilized the highly collaborative Integrated Project Delivery (IPD) method which was very successful and saved nearly $1.5 M in project costs. TAI was one of the seven prime level members of the IPD project.
